The ability to insure against idiosyncratic endowment risk depends on the organization of markets and the availability of consumption insurance. When all agents are identical ex ante and there are complete contingent claims, then full insurance can be achieved. Simple frictions, such as...

The q-theory explanations of asset pricing anomalies are quantitatively important. We perform a new asset pricing test by using GMM to minimize the difference between average stock returns in the data and average investment returns constructed from observable firm characteristics. Under various...

Evidence of stock return predictability by financial ratios is still controversial, as documented by inconsistent results for in-sample and out-of-sample regressions and by substantial parameter instability. This paper shows that these seemingly incompatible results can be reconciled if the...

Empirical methods in corporate finance for some time focused on the short-term market reaction to corporate announcements. The associated theories rely heavily on market imperfections such as taxes, transaction costs, information issues and contracting problems to obtain short-term market...

This paper develops a simple competitive model of CEO pay. It appears to explain much of the rise in CEO compensation in the US economy, without assuming managerial entrenchment, mishandling of options, or theft. CEOs have observable managerial talent and are matched to assets in a competitive...

This paper exhibits dynamic features of insurance contracts in the empirical analysis of moral hazard. We first show that experience rating implies negative occurrence dependence under moral hazard: individual claim intensities decrease with the number of past claims. We then show that dynamic...

This paper contributes to the literature comparing the relative performance of financial intermediaries and markets by studying an environment in which a trade-off between risk sharing and growth arises endogenously. Financial intermediaries provide insurance to households against a liquidity...
