Within the penalized model selection (PMS) approach the selected model is defined by minimization of penalized empirical risk. Such procedures enjoy nice algorithmic properties especially if both the empirical risk and the penalty function are convex functions of the parameter. A number of ``...

Aggregation of information provided by experts is usually conceived as independent from the decision maker's preferences. We argue that this entails a substantial loss, insofar as it precludes the possibility to take into account simultaneously the decision maker's attitude towards disensus among...

Maternal deaths accounted for over 15% of all deaths of women in prime age years until the mid-1930s in the U.S. Starting in 1936, the maternal mortality rate dropped dramatically, reaching modern levels by the early 1950s. The female-male differential in life expectancy at age twenty rose from one...

We propose a continuous time infinite horizon equilibrium model of financial markets in which arbitrageurs have multiple valuable investment opportunities but face financial constraints. The investment opportunities, heterogeneous along different dimensions, are provided by pairs of similar assets...

This paper analyzes the impacts of bioenergy trade on greenhouse gas emissions using a two-good, three-factor model. Bioenergy is an intermediate good produced by the agricultural sector and used by the industry as a substitute for fossil fuels. Countries impose Pigovian taxes on pollution emitted...

We develop a methodology to collect and analyze time diaries of top executives. Our idea -sketched out in a simple theoretical set-up -is that CEO time is a scarce resource and that its allocation can help us identify the firm's priorities as well as the presence of governance issues. We record the...

We develop a theory of imperfect competition with loss-averse consumers. All consumers are fully informed about match value and price at the time they make their purchasing decision. However, a share of consumers is initially uncertain about their tastes and forms a reference point consisting of an...

Using panel data on Chinese provinces over 27 years, we show that local public policy to a large extent is determined by the background of provincial leader, i.e., provincial party secretary. Provinces under the leadership of party secretaries who built their careers within the province have higher...

This paper studies the unique risk characteristics of organization capital. Using a stock measure of organization capital based on readily available accounting data, we find that firms with more organization capital relative to their industry peers outperform firms with less organization capital by...
