I argue that the lumpiness of firm investment behavior matters for asset prices, in both the time-series and cross-section. I propose a production-based asset pricing model which reproduces nearly 100\% of both the observed equity premium and its volatility through large volatility in marginal utility. Incorporating the habit reversal behavior into the positive habit formation in the Campbell-Cochrane preferences is essential to generate this volatile marginal utility. In the cross-section, small and non-adjusting firms earn larger equity premiums than big and adjusting firms when the capital adjustment costs are shaped to respect the evidence on lumpy distribution of firm investment.
