Abstract:
This paper presents new evidence on the distribution of risk attitudes in the population, using a novel set of survey questions and a representative sample of roughly 22,000 individuals living in Germany. Using a question that asks about willingness to take risks in general, on an 11-point scale, we find evidence of heterogeneity across individuals, and show that willingness to take risks is negatively related to age and being female, and positively related to height and parental education. We test the behavioral relevance of this survey measure by conducting a complementary field experiment, based on a representative sample of 450 subjects, and find that the general risk question is a good predictor of actual risk-taking behavior. We then use a more standard lottery question to measure risk preferences in our sample of 22,000, and find similar results regarding heterogeneity and determinants of risk preferences, compared to the general risk question. The lottery question also makes it possible to estimate the coefficient of relative risk aversion for each individual in the sample. Using five questions about willingness to take risks in specific domains - car driving, financial matters, sports and leisure, career, and health - the paper also studies the impact of context on risk attitudes, finding a strong but imperfect correlation across contexts. Using data on a collection of risky behaviors from different contexts, including traffic offences, portfolio choice, smoking, occupational choice, participation in sports, and migration, the paper compares the predictive power of all of the risk measures. Strikingly, the general risk question predicts all behaviors whereas the standard lottery measure does not. The best predictor for any specific behavior is typically the corresponding context-specific measure.

Abstract:
This paper attempts to add to the understanding of the causes for the differing recent developments in inequality in OECD countries. The similarity of shocks and technological changes affecting these countries suggests that interactions of these shocks and country-specific institutions are responsible for the diverging inequality patterns. The paper suggests a channel complementary to those investigated in recent contributions, focusing on the impact of education. A microfoundation of human capital formation is proposed, emphasizing heterogeneity of individuals and multidimensionality of human capital. The reactions in individual behavior triggered by technological change are crucially affected by the education system and are shown to be responsible for the divergent developments in inequality.

Abstract:
This paper presents a microfounded theory of long-term development. We model the interplay between economic variables, namely the process of human capital formation and technological progress, and the biological constraint of finite lifetime expectancy. All these processes affect each other and are endogenously determined. The model is analytically solved and simulated for illustrative purposes. The resulting dynamics reproduce a long period of stagnant growth as well as an endogenous and rapid transition to a situation characterized by permanent growth. This transition can be interpreted as industrial revolution. Historical and empirical evidence is discussed and shown to be in line with the predictions of the model.

Abstract:
We analyze the endogenous evolution of economic and political institutions and the interdependencies with the process of economic development. Favorable economic institutions ensure the appropriability of rents in form of a state of law. We study the conditions under which a state of law can be implemented under oligarchy, and when democratization is necessary. Inequality in endowments and incomes prolongs the absence of good institutions and delays democratization. Conversely, institutions shape the income distribution. Simulations illustrate how inequality affects the development process and may lead to overtaking and divergence. The implications are in line with historical and empirical evidence.

Abstract:
This paper tests two hypotheses from the theory of elimination tournaments: (i) that uneven tournaments, where the contestants are ex ante heterogeneous, entail lower effort exertion; this is a prediction from agency theory that has not been tested empirically before; and (ii) whether incentives set through prizes matter for effort exertion; this assumption underlies any agency theory about elimination tournaments, and has been empirically tested in other contexts. The evidence obtained with data from professional tennis tournaments supports both the assumption that incentives matter, as well as the theoretical implications concerning uneven tournaments among heterogeneous contestants.

Abstract:
Recent theoretical contributions depart from the usual practice of treating individual attitude endowments as a black box, by assuming that these are shaped by the attitudes of parents and other role models. Attitudes include fundamental preferences such as risk preference, and crucial beliefs about the world, such as trust. This paper provides evidence on the three main mechanisms for attitude transmission highlighted in the theoretical literature: (1) transmission of attitudes from parents to children; (2) positive assortative mating of parents, which tends to reinforce the impact of parents on the child; (3) an impact of prevailing attitudes in the local environment. Investigating these mechanisms is important because they are crucial assumptions underlying a large literature. It also sheds light on the basic question of where individual attitude endowments come from, and the factors that determine these drivers of economic behavior. The findings are supportive of attitude transmission models, and indicate that all three mechanisms play a role in shaping economically relevant attitudes.

Abstract:
Is the way that people make risky choices, or tradeoffs over time, related to cognitive ability? This paper investigates whether there is a link between cognitive ability, risk aversion, and impatience, using a representative sample of the population and incentive compatible measures. We conduct choice experiments measuring risk aversion, and impatience over an annual time horizon, for a randomly drawn sample of roughly 1,000 German adults. Subjects also take part in two different tests of cognitive ability, which correspond to sub-modules of one of the most widely used IQ tests. Interviews are conducted in subjects' own homes. We find that lower cognitive ability is associated with greater risk aversion, and more pronounced impatience. These relationships are significant, and robust to controlling for personal characteristics, educational attainment, income, and measures of credit constraints. We perform a series of additional robustness checks, which help rule out other possible confounds.

Abstract:
Prominent economic theories have emphasized the role of commonly held perceptions and expectations for determining macroeconomic outcomes. A key empirical question is how such collectively held beliefs are formed. We use the FIFA World Cup 2006 as a natural experiment. We provide direct evidence that seemingly irrelevant events (the outcomes of soccer matches) can systematically affect individual perceptions about economic prospects, both on a personal and economy-wide level.

Abstract:
This paper provides a unified theory of the economic and demographic transition. Individuals make optimal decisions about fertility, education of their children and the type and intensity of the investments in their own education. These decisions are affected by different dimensions of mortality and technological progress which change endogenously during the process of development. The model generates an endogenous transition from a regime characterized by limited human capital formation, little longevity, high child mortality, large fertility and a sluggish income and productivity growth to a modern growth regime in which lower net fertility is associated with the acquisition of human capital and improved living standards. Unlike previous models, the framework emphasizes the education composition of the population in terms of the equilibrium share of educated individuals, and differential fertility related to education. The framework explores the roles of different dimensions of mortality, wages and schooling in triggering the transition. The dynamics of the model are consistent with empirical observations and stylized facts that have been difficult to reconcile so far. For illustration we simulate the model and discuss the novel predictions using historical and cross-country data.

Abstract:
This paper offers a rationale for limiting the delegation of (real) authority, which neither relies on insurance arguments nor depends on ownership structure. We analyse a repeated hidden action model in which the actions of a risk neutral agent determine his future outside option. Consequently, the agent can improve his future bargaining position, which gives the principal an incentive to retain sufficient control over the agent's actions. Using respective one-period contracts, the principal can implement the efficient outcome while "selling the shop" to the agent is sub-optimal. This provides an argument for integration if the boundary of the firm is defined by control rights rather than the entitlement to revenues.

Abstract:
We study the process of endogenous democratization from inefficient oligarchic systems in an economy where heterogeneous individuals can get involved in predation activities. The features of democracies are shown to be crucially related to the conditions under which democratization initially takes place. The political regime and the extent of redistribution implemented under it depend on the allocation of de facto political power across the different social groups. The cost of public enforcement of property rights depends on the extent of predation activities in the economy. The theory highlights the importance of inequality in natural resources and availability of human capital for endogenous democratic transitions. Multiple politico-economic equilibria can be sustained conditional on expectations about property rights enforcement. This generates history dependence. Democratic transitions supported by a large consensus serve as coordination device and lead to better protection of property and more stable political systems than democratic transitions imposed in conflictual environments. We test the novel predictions using available cross-country data. The link between the type of democratic transition and the outcomes under democracy is also investigated using novel data on constitutional principles. The findings support the theoretical predictions.

Abstract:
Experimental evidence has convincingly shown the existence of reciprocal inclinations, i.e., a tendency for people to respond in-kind to hostile or kind actions. Little is known, however, about: (i) the prevalence of reciprocity in the population, (ii) individual determinants of reciprocity, (iii) the correlation between positive and negative inclinations within person, and (iv) consequences of reciprocal inclinations for wages, subjective well-being, friendships and other economic and social outcomes. Answering these questions requires moving out of the lab and using a large and representative subject pool, which combines information about subjects' reciprocal inclinations with extensive socioeconomic background information. In this paper we measure the reciprocal inclinations of 21,000 individuals. We show that most people state reciprocal inclinations, in particular in terms of positive reciprocity. However, there is substantial heterogeneity in the degree of reciprocity, and quite surprisingly, only a weak correlation between positive and negative reciprocity for an individual. In terms of determinants, being female, and increasing age, lead to greater positive and less negatively reciprocal tendencies. Taller people are more positively reciprocal, but height has no impact on negative reciprocity. The asymmetric impact of these determinants provides further indication that positive and negative reciprocity are fundamentally different traits, rather than the outcome of a single underlying tendency. In terms of economic implications, we provide the first evidence using a large representative survey that corroborates an important hypothesis arising from laboratory experiments: Positively reciprocal workers are in fact paid more, and exert greater effort, on the job. Moreover, positively reciprocal people are more likely to be employed, report having more close friends, and have a higher overall level of life satisfaction. In this sense, Homo Reciprocans - in the positive domain - is in fact more successful than his or her non-reciprocal fellows.

Abstract:
This paper investigates whether risk aversion and impatience are correlated with cognitive ability. We conduct incentive compatible choice experiments measuring risk aversion, and impatience over an annual time horizon, for a representative sample of roughly 1,000 German adults. A measure of cognitive ability is provided by two submodules of one of the most widely used IQ tests. Interviews are conducted in subjects' own homes. We find that lower cognitive ability is associated with greater risk aversion, and more pronounced impatience. These relationships are statistically and economically significant, and robust to controlling for personal characteristics, educational attainment, income, and measures of liquidity constraints. We perform a series of additional robustness checks, which help rule out other possible confounds.

Abstract:
Using cross-country data, we find evidence for a significant negative interaction effect between democracy and inequality in determining the quality of growth-promoting institutions like rule of law. Democracy is associated with institutions of higher quality when inequality is lower.

Abstract:
This paper investigates spatial correlation in the matching process of vacant jobs and job seekers. The importance of the interactions of regional labor markets in West Germany is highlighted in several dimensions. We test for spatial autocorrelation in regional hires, unemployment and vacancy levels, we examine the patterns of new matches in regions, identify clusters of regions of particularly intense interregional matching, and examine the effects of German re-unification. After setting-out a simple model of endogenous regional mobility and endogenous on-the-job search, we analyze the composition of new hires with respect to regional origin and previous employment status, the determinants of this composition, and the interaction of these characteristics. The results shed new light on the puzzle raised in the literature, which finds a large variation in unemployment rates, combined with little inter-regional migration. We find evidence in favor of labor market determined migration and against the "internal migration puzzle" found for other European countries and partly for the United States.

Abstract:
This paper makes two contributions to the empirical matching literature. First, a recent study by Anderson and Burgess (2000) testing for endogenous competition among job seekers in a matching frame-work, is replicated with a richer and more accurate data set for Germany. Their results are confirmed and found to be surprisingly robust. Second, the matching framework is augmented by endogenous strategic hiring behavior on the side of vacancy-posting firms. Neglecting job competition, the relevance of strategic hiring is shown using the same empirical strategy. At the same time, the test is shown to be invalid if both types of endogenous behavior are present.

Abstract:
This paper deals with empirical matching functions. The paper is innovative in several ways. First, unlike in most of the existing literature, matching functions are estimated not only on aggregate, but also on disaggregate levels which is unusual due to the scarcity of appropriate data. Moreover, the unique data set used allows to distinguish inflows into jobs by sources. Results for different measures of flows found in the literature can therefore be replicated using a single data set. Labor markets can be disaggregated by occupations, rather than by industries or regions. Furthermore, disaggregation is possible for age and educational groups. The paper allows detailed insights into the pattern of frictions in labor markets, on mismatch and labor market tightness, and therefore provides valuable information necessary for the conduct of labor market policies.

Standard search theory assumes that individuals know, with certainty, how they compare to competing searchers in terms of ability. In contrast, we hypothesize that searchers are uncertain about relative ability, with important implications for search behavior. We test our hypotheses in a laboratory experiment. The first main finding is that people are substantially uncertain about whether they are a type with a high or low probability of success, determined by being above or below the median in terms of ability. Self-confidence, defined as an individual's self-assessed probability of being a high type, is too high (above zero) for many low types, and too low (below 1) for many high types. Second, people update beliefs based on search outcomes. Self-confidence increases or decreases in the right direction, but is less sensitive to new information than predicted by Bayes' rule. Third, updating affects future search decisions: people are less likely to search as confidence about being a high type falls. Fourth, some search too little, and others search too much, due to wrong beliefs. Fifth, at the end of the experiment a substantial fraction turn down the chance to learn their exact rank. These are overwhelmingly those with low ability, suggesting an aversion to learning that one is one of the worst performers. Given that people are uncertain even in the simple setting of our experiment, our evidence strongly suggests that uncertainty about ability is relevant in more complex, real-world search settings, including search for a job or search for a mate. Focusing on the case of job search, we discuss how our findings can provide a new explanation for various important stylized facts from field evidence.

Abstract:
By applying a stochastic production frontier approach to the matching process of unemployed and vacancies, this paper provides novel detailed insights into the process of job creation. For different labor markets as defined by occupation and region, the methodology produces estimates of the relative importance of demand and supply factors for the creation of new jobs, and of the overall efficiency of job creation. Some crucial determinants of the overall matching efficiency are identified and analyzed. This allows to make differentiated statements about the appropriateness of labor market policies, and therefore provides policy makers with novel relevant information.

Abstract:
Starting in January 2003, Germany implemented the first two so-called Hartz reforms, followed by the third and fourth packages of Hartz reforms in January 2004 and January 2005, respectively. The aim of these reforms was to accelerate labor market flows and reduce unemployment duration. Without attempting to evaluate the specific components of these Hartz reforms, this paper provides a first attempt to evaluate the overall effectiveness of the first two reform waves, Hartz I/II and III, in speeding up the matching process between unemployed and vacant jobs. The analysis is conceptually rooted in the flow-based view underlying the reforms, estimating the structural features of the matching process. The results indicate that the reforms indeed had an impact in making the labor market more dynamic and accelerating the matching process.

Abstract:
Geographic mobility is important for the functioning of labor markets because it brings labor resources to where they can be most efficiently used. It has long been hypothesized that individuals' migration propensities depend on their attitudes towards risk, but the empirical evidence, to the extent that it exists, has been indirect. In this paper, we use newly available data from the German Socio-Economic Panel to measure directly the relationship between migration propensities and attitudes towards risk. We find that individuals who are more willing to take risks are more likely to migrate between labor markets in Germany. This result is robust to stratifying by age, sex, education, national origin, and a variety of other demographic characteristics, as well as to the level of aggregation used to define geographic mobility. The effect is substantial relative to the unconditional migration propensity and compared to the conventional determinants of migration. We also find that being more willing to take risks is more important for the extensive than for the intensive margin of migration.

Abstract:
This paper investigates the efficiency of the matching process between job seekers and vacancy posting firms in West-Germany, using variation across labor market regions and across time. The results of a stochastic frontier analysis shed new light on extent and regional differences of search frictions, on potential determinants of frictional inefficiencies and on the consequences of German reunification for the matching process. The paper also presents novel evidence on the complex interactions between spatial contingencies among regional labor markets: matching efficiency decreases with spatial autocorrelation in hiring, implying indirect evidence for crowding externalities.

Abstract:
The paper examines real and nominal wage rigidities. We estimate a switching regime model, in which the observed distribution of individual wage changes, computed from West German register data for 1976-1997, is generated by simultaneous processes of real, nominal or no wage rigidity, and measurement error. The fraction of workers facing wage increases that are due to nominal, but mostly real wage rigidity is substantial. The extent of real rigidity rises with inflation, whereas the opposite holds for nominal rigidity. Overall, the incidence of wage rigidity, which accelerates unemployment growth, is most likely minimized in an environment with moderate inflation.

Abstract:
In this paper we investigate the causal effect of life expectancy on economic growth by explicitly accounting for the role of the demographic transition. In addition to focusing on issues of empirical identification, this paper emphasizes the role of the econometric specification. We present a simple theory of the economic and demographic transition where individuals' education and fertility decisions depend on their life expectancy. The theory predicts that before the demographic transition improvements in life expectancy primarily increase population. Improvements in life expectancy do, however, reduce population growth and foster human capital accumulation after the onset of the demographic transition. This implies that the effect of life expectancy on population, human capital and income per capita is not the same before and after the demographic transition. Moreover, a sufficiently high life expectancy is ultimately the trigger of the transition to sustained income growth. We provide evidence supporting these predictions using data on exogenous mortality reductions in the context of the epidemiological revolution.

Abstract:
This paper investigates whether risk preferences explain how individuals are sorted into occupations with different earnings variability. We exploit data from the German Socio-Economic Panel, which contains a subjective assessment of willingness to take risks whose behavioral relevance has been validated in previous work. As a measure of earnings risk, we use the cross-sectional variation in earnings that is left unexplained by human capital in Mincerian wage regressions. By relating earnings risk to the measure of individual risk preference, our evidence shows that individuals with low willingness to take risks are more likely to be sorted into occupations with low earnings risk. This pattern is found regardless of the level of occupation categories, region, gender and labor market experience. We also find that risk preferences are significant determinant of wages in a Mincer regression, illustrating the importance of preferences and attitudes in addition to more standard regressors.

Abstract:
This paper develops a model of equilibrium unemployment with (unobservable) endogenous on-the-job search and (partly unobservable) endogenous search behavior by firms. The model allows to analyze crowding-out of unemployed job seekers by endogenous on-the-job search of employees, and the interaction of job search behavior and vacancy posting policies of firms. Moreover, it is shown that the neglect of endogenous but not observable behavior in the empirical literature on labor matching leads to systematically biased estimates of the matching elasticities, posing a caveat on the results of previous studies testing for constant returns of the matching function. The theoretical model presented allows to predict the direction of the bias. We propose a correction for the estimates of empirical matching functions that leads to unbiased estimates of the matching elasticities. The empirical implications of the theoretical model are tested and confirmed using German administrative data, and unbiased estimates of matching elasticities are presented.

Abstract:
This paper presents a model of the labor market in which unemployed workers are uncertain about their relative ability to find a job. Unsuccessful search induces individuals to revise their beliefs downwards. Once self-confidence is sufficiently low, workers become discouraged and give up on search. This non-stationarity gives rise to structural flows from unemployment to non-participation in equilibrium. In contrast, existing models typically maintain stationarity and appeal to exogenous stochastic shocks to generate transitions from unemployment to non-participation. Our model is based on relaxing a single assumption in a standard matching framework - workers are uncertain about their job finding probability - and yet the model generates a variety of important implications. Our alternative assumption is supported by experimental evidence. The first implication of the model is a declining hazard from unemployment to employment, arising due to erosion of self-confidence in search. Second, because search outcomes are only a noisy signal about ability, some individuals can become overly discouraged and stop search too early due to wrong beliefs. Finally, workers with greater unemployment duration are less confident, and thus have a worse threat point in wage bargaining. Consequentially, they earn lower starting wages even if they are identical in terms of objective productivity. We discuss how the model provides a new, unifying explanation for a variety of important facts from field evidence.

Abstract:
Wage rigidity the observation that wages cannot be adjusted downwards has important implications for labor markets and macroeconomic performance. Empirical evidence on the extent, causes and consequences of wage rigidity on the individual level is relatively scant, however. This Feature presents articles that apply a new methodology to estimate the incidence and extent of nominal and real wage rigidity among the employed in three major European countries (Germany, Italy and Great Britain). The results document the pervasiveness of nominal and, particularly, real wage rigidity in different institutional and economic environments, and a recent decline in real wage rigidity.

Abstract:
Prominent economic theories have emphasized the role of commonly held perceptions and expectations for determining macroeconomic outcomes. A key empirical question is how such collectively held beliefs are formed. We use the FIFA World Cup 2006 as a natural experiment. We provide direct evidence that seemingly irrelevant events (the outcomes of soccer matches) can systematically affect individual perceptions about economic prospects, both on a personal and economy-wide level.

Abstract:
Many economic decisions involve a substantial amount of uncertainty, and therefore crucially depend on how individuals process probabilistic information. In this paper, we investigate the capability for probability judgment in a representative sample of the German population. Our results show that almost a third of the respondents exhibits systematically biased perceptions of probability. The findings also indicate that the observed biases are related to individual economic outcomes, which suggests potential policy relevance of our findings.

Abstract:
In this paper we discuss the complementarity of laboratory and field data. Experiments offer highly controlled environments that allow precise testing and causal inferences. Survey and field data on the other hand provide information on large and representative samples of people interacting in their natural environment. We discuss several concrete examples how to combine lab and field data and how to exploit potential complementarities. One example describes an experiment, which is run with a representative sample to guarantee control and representativeness. The second example is based on the idea to experimentally validate survey instruments to ensure behavioral validity of instruments that can be used in existing panel data sets. The third example describes the possibility to use the lab to identify causal effects, which are tested in large data sets. Topics discussed in this paper comprise the relation of cognitive skills (IQ) and risk and time preferences, determinants, prevalence and economic consequences of risk attitudes, selection into incentive schemes and the impact of unfair pay on stress.

Abstract:
Experimental evidence has convincingly shown the existence of reciprocal inclinations, i.e., a tendency for people to respond in-kind to hostile or kind actions. Little is known, however, about: (i) the prevalence of reciprocity in the population, (ii) individual determinants of reciprocity, (iii) the correlation between positive and negative inclinations within person, and (iv) consequences of reciprocal inclinations for wages, subjective well-being, friendships and other economic and social outcomes. Answering these questions requires moving out of the lab and using a large and representative subject pool, which combines information about subjects' reciprocal inclinations with extensive socioeconomic background information. In this paper we measure the reciprocal inclinations of 21,000 individuals. We show that most people state reciprocal inclinations, in particular in terms of positive reciprocity. However, there is substantial heterogeneity in the degree of reciprocity, and quite surprisingly, only a weak correlation between positive and negative reciprocity for an individual. In terms of determinants, being female, and increasing age, lead to greater positive and less negatively reciprocal tendencies. Taller people are more positively reciprocal, but height has no impact on negative reciprocity. The asymmetric impact of these determinants provides further indication that positive and negative reciprocity are fundamentally different traits, rather than the outcome of a single underlying tendency. In terms of economic implications, we provide the first evidence using a large representative survey that corroborates an important hypothesis arising from laboratory experiments: Positively reciprocal workers are in fact paid more, and exert greater effort, on the job. Moreover, positively reciprocal people are more likely to be employed, report having more close friends, and have a higher overall level of life satisfaction. In this sense, Homo Reciprocans - in the positive domain - is in fact more successful than his or her non-reciprocal fellows.

Abstract:
We present a theory of the economic and demographic transition where adult longevity, child mortality, fertility and the education composition of the population are jointly determined. The model allows for an investigation of the determinants of underdevelopment traps as well as of the mechanism that leads to an endogenous exit out of the trap. We also study the different roles of exogenous reductions in mortality and of permanent differences in extrinsic mortality for comparative development. The theory delivers a series of novel predictions which are illustrated with a simple dynamic simulation of the model. These predictions are shown to be consistent with evidence using both time series data and cross-country panel data.

Abstract:
This article examines real and nominal wage rigidities in West Germany. Using regionally disaggregated register data for 1975-2001, we estimate the extent of both types of wage rigidities from the observed distribution of individual wage changes, taking into account possible measurement error. The fraction of workers facing wage increases that are caused by nominal and particularly real wage rigidity is substantial. The extent of real rigidity rises with inflation and falls with regional unemployment, whereas the opposite holds for nominal rigidity. Overall, the incidence of wage rigidity, which accelerates unemployment growth, is most likely minimized in a moderate inflation environment.

Abstract:
This paper shows that conventional empirical estimates of matching functions are systematically biased, because unobservable and endogenous search behaviour, such as on-the-job search by workers or the use of different search channels by firms, is neglected. I propose an approach for recovering unbiased elasticities under different scenarios of competition for workers and jobs without the need for constructing proxies for unobserved stocks of searchers and vacancies. Using German administrative data, I estimate the biases affecting conventional studies and derive bias-corrected estimates of the matching elasticities under different scenarios.

Abstract:
This paper provides evidence about the determinants of trust and reciprocal inclinations, that is, a tendency for people to respond in kind to hostile or kind actions, in a representative setting. We investigate the prevalence of reciprocity in the population, the correlation between trust and positive and negative reciprocal inclinations within person, the individual determinants of reciprocity, and the relationship with psychological measures of personality. We find that most people state reciprocal inclinations, in particular in terms of positive reciprocity, as well as substantial heterogeneity in the degree of trust and reciprocity. Trust and positive reciprocity are only weakly correlated, while trust and negative reciprocity exhibit a negative correlation. In terms of determinants, being female and increasing age are associated with stronger positive and weaker negative reciprocal tendencies. Taller people are more positively reciprocal, but height has no impact on negative reciprocity. Psychological traits also affect trust and reciprocity. (JEL D63, J3, J6)

Abstract:
This article complements the experimental literature that has shown the importance of reciprocity for behaviour in stylised labour markets or other decision settings. We use individual measures of reciprocal inclinations in a large, representative survey and relate reciprocity to real world labour market behaviour and life outcomes. We find that reciprocity matters and that the way in which it matters is very much in line with the experimental evidence. In particular, positive reciprocity is associated with receiving higher wages and working harder. Negatively reciprocal inclinations tend to reduce effort. Negative reciprocity increases the likelihood of being unemployed.

Abstract:
This article studies the endogenous evolution of economic and political institutions and the interdependencies with the process of economic development. Favourable economic institutions in the form of a state of law and absence of societal conflict arise in equilibrium. Democracies are neither necessary nor sufficient to implement a state of law, even if they may be instrumental. Efficient oligarchies can emerge and persist supported by the consensus of all groups. A taxonomy of politico-economic equilibria shows the endogenous evolution of institutions depending on economic inequality and natural resource abundance, implying a non-monotonic relationship between inequality and institutional quality.

Abstract:
Recent theoretical contributions depart from the usual practice of treating individual attitude endowments as a black box, by assuming that these are shaped by the attitudes of parents and other role models. Attitudes include fundamental preferences such as risk preference, and crucial beliefs about the world, such as trust. This paper provides evidence on the three main mechanisms for attitude transmission highlighted in the theoretical literature: (1) transmission of attitudes from parents to children; (2) positive assortative mating of parents, which tends to reinforce the impact of parents on the child; (3) an impact of prevailing attitudes in the local environment. Investigating these mechanisms is important because they are crucial assumptions underlying a large literature. It also sheds light on the basic question of where individual attitude endowments come from, and the factors that determine these drivers of economic behaviour. The findings are supportive of attitude transmission models, and indicate that all three mechanisms play a role in shaping economically relevant attitudes.

Abstract:
This paper investigates the endogenous emergence of democracy and rule of law in an economy where heterogeneous individuals can get involved in predation activities. Decisions about public policies concern the extent of fiscal redistribution and property rights, whose costs depend on the extent of predation in the population. We characterize the dynamic evolution of the economy in which both the political regimes and public policies are endogenously determined. The theory delivers several novel results. Multiple politico-economic equilibria involving different public policies can be sustained conditional on beliefs about property rights enforcement. Democratization is endogenous, but the features of democracies are shown to be crucially related to the conditions under which democratization initially takes place. Democratic transitions supported by a large consensus serve as coordination device and lead to better protection of property and more stable political systems than democratic transitions imposed under conflictual environments. Conflictual transitions lead to failed democracies with potentially worse property rights protection than oligarchies. The novel predictions are in line with existing evidence and with results from newly collected data on constitutional principles.
