Business strategy can be defined as a firm's plan to generate economic profits based on lower cost, better quality, or new products. The analysis of business strategy is thus at the intersection of market competition and a firm's efforts to secure persistently superior performance via...

We introduce a new, market-based and forward looking measure of political risk derived from the yield spread between a country's U.S. dollar debt and an equivalent U.S. Treasury bond. We explain the variation in these sovereign spreads with four factors: global economic conditions,...

We find that active mutual funds perform better after trading more. This time-series relation between a fund’s turnover and its subsequent benchmark-adjusted return is especially strong for small, high-fee funds. These results are consistent with high-fee funds having greater skill to identify...

This paper analyzes a class of competitive economies with production, incomplete financial markets, and agency frictions. Firms take their production, financing, and contractual decisions so as to maximize their value under rational conjectures. We show that competitive equilibria exist and that...

In a sample of 110 countries over the period 1960-2009, we document a positive relation between the volatility and skewness of growth in the cross-section. The relation holds regardless of initial level of economic development and of subsequent long-run growth rate. We argue that this novel...

Parameter learning strongly amplifies the impact of macro shocks on marginal utility when the representative agent has a preference for early resolution of uncertainty. This occurs as rational belief updating generates subjective long-run consumption risks. We consider general equilibrium models...

During the past few decades, the fraction of the equity market owned directly by individuals declined significantly. The same period witnessed investment trends that include the growth of indexing as well as shifts by active managers toward lower fees and more index-like investing. I develop an...

We empirically analyze the nature of returns to scale in active mutual fund management. We find strong evidence of decreasing returns at the industry level: As the size of the active mutual fund industry increases, a fund's ability to outperform passive benchmarks declines. At the fund level,...

We find support for two key predictions of an agency theory of unproductive corporate social responsibility. First, increasing managerial ownership decreases measures of firm goodness. We use the 2003 Dividend Tax Cut to increase after-tax insider ownership. Firms with moderate levels of insider...

This paper describes our construction of the Global Financial Development Database and uses the data to compare financial systems around the world. The database provides information on financial systems in 205 economies over the period from 1960 to 2010 and includes measures of (1) size of...
