In this paper we empirically investigate to what extent three competing asset pricing models price an individual firm's stock differently in an internationally integrated world: (i) the multifactor ICAPM of Solnik-Sercu including both the global market portfolio and exchange rate risk premiums, (ii) the single factor ICAPM with only the global market portfolio, and (iii) the single factor domestic CAPM. We generalize the pricing error expressions of Stulz (1995b) for the domestic CAPM against the single factor ICAPM to the multifactor model with exchange rate factors included. Furthermore, we derive formal statistical tests for the existence of a pricing error of the domestic CAPM versus both the single factor ICAPM and the multifactor ICAPM. We test for the significance of these pricing errors in a sample of 2,483 firms from 10 industrialized countries using monthly data from 1980 to 1995. We find that the single factor ICAPM without exchange rate factors induces mispricing for more than 60% of all firms. The domestic CAPM leads to a substantial and statistically significant pricing error for approximately 7% of all firms.
