I provide new evidence on the failure of the Q-theory. The Q-theory implies the state-by-state equivalence of stock and investment returns|a important implication of many asset pricing models. Using aggregate US data, I find there exists a realistic parameterization of the aggregate production...

Empirically, the conditional volatility of aggregate consumption growth varies over time. While many papers test the consumption CAPM based on realized consumption growth, little is known about how the time-variation of consumption growth volatility affects asset prices. We show that in a model...

A firm seeks to raise capital in credit markets to fund risky operating activities. The firm has private information about the future cash flows from such activities. Firm owners delegate operating decisions to a manager who privately learns further information about the distribution of those...

While aggregate earnings should affect aggregate stock returns, standard portfolio theory predicts that the cross-sectional dispersion in firm-level earnings would not affect aggregate stock returns. Nonetheless, this paper demonstrates a surprisingly robust relation between cross-sectional...

The question we ask is: within the set of a three-period-lived OLG economies with a stochastic endowment process, a stochastic dividend process, and sequentially incomplete complete markets, under what set of conditions may a set of government transfers dynamically Pareto dominate the laissez...

Piracy has been a major problem for perpetually licensed software. Usage-based licensing architecture such as pay-per-use or software-as-a-service can offer technology-based protection against piracy. We provide an analytical framework to examine the economic implications of pay-per-use versus...

Advances in information technology increasingly allow firms to identify expensive, high-cost customers, who are not only individually less profitable for firms but also raise the average marginal cost incurred by firms and thus impose a negative externality on inexpensive customers. Should...

In the macroeconomic literature, the implications of a context with household heterogeneity and incomplete financial markets have been mostly studied under the assumption that households own the physical capital and undertake the intertemporal investment decision. Further, firms rent capital and...

We study the quantitative properties of constrained efficient allocations in an environment where risk sharing is limited by the presence of private information. We consider a life cycle version of a standard Mirrlees economy where shocks to labor productivity have a component that is public...

Several factors suggest that meaningful network neutrality rules will not be enshrined in near-term U.S. telecommunications policy. These include disagreements over the need for such rules as well as their definition, efficacy and enforceability. However, as van Schewick (2005)1 has demonstrated...
