Many seemingly discordant results are reconciled if firm-specific return volatility is characterized as the intensity with which firm-specific events occur. A functionally efficient stock market allocates capital to its highest value uses, which often amounts to financing Schumpeterian creative...

We examine the role of patents as signals used to reduce information asymmetries in entrepreneurial finance. A theoretical model gives conditions for a unique separating equilibrium in which startup founders file for patents to signal invention quality to investors, as well as appropriating...

Countries that cannot attract foreigners to invest in their local currency bonds run the risk of currency mismatches that can result in painful crises. We analyze foreign participation in the bond markets of over 40 countries. Bond markets in less developed countries have returns characterized...

We present a framework for the study of risk and return of household enterprise in developing economies. We make predictions from two polar benchmarks: (1) an economy with Pareto optimal allocations under full risk sharing, and (2) an economy in which each autarky household absorbs risk in...

We measure heterogeneity in risk aversion among households in Thai villages using a full risk-sharing model and complement the results with a measure based on optimal portfolio choice. Among households with relatives living in the same village, full insurance cannot be rejected, suggesting that...

We organize both literatures around three basic questions: (a) how to measure illiquidity, (b) how illiquidity relates to underlying market imperfections and other asset characteristics, and (c) how illiquidity...

Berkshire Hathaway has realized a Sharpe ratio of 0.76, higher than any other stock or mutual fund with a history of more than 30 years, and Berkshire has a significant alpha to traditional risk factors. However, we find that the alpha becomes insignificant when controlling for exposures to...

Stocks with large increases in call implied volatilities over the previous month tend to have high future returns while stocks with large increases in put implied volatilities over the previous month tend to have low future returns. Sorting stocks ranked into decile portfolios by past call...
