Focusing on the interaction between national brands and private labels, this paper has two main empirical contributions: i) a simultaneous system of demand (share), price and expenditure equations is estimated, and ii) differences in the structure of the local geographic market are incorporated...

Prices for nearly all basic commodity rose at unprecedented rates throughout early 2008, only to fall nearly as fast as financial markets and global economies began to collapse. Rising food prices in 2008 led to concerns that commodity price spikes would lead to more general food inflation, but...

This dissertation empirically studies demand complementarities in automobile purchases using newly collected Japanese household-level panel data, Keio Household Panel Survey. It is motivated by the observation that approximately one third of Japanese households own more than one automobile and...

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...
