This paper examines the stock market reactions to US biotech firms’ innovation news announcements during 1983-1993. Besides the positive abnormal returns observed during the announcement period, the paper identifies a medium-horizon negative drift in the stock price subsequent to firms’ innovative events. The observed negative drift is robust to the benchmarks and procedures used in calculating...

In its complexity and its vulnerability to market volatility, the CPDO might be viewed as the poster child for the excesses of financial engineering in the credit market. This paper examines the CPDO as a case study in model risk in the rating of complex structured products. We demonstrate that the models used by S&P and Moody’s would have assigned very low probability to the spread levels real...

To inform theory and to investigate the practical application of prediction markets in a setting where the distribution of information across agents is critical, we conducted markets designed to forecast post-IPO valuations before a particularly unique IPO: Google. Because prediction markets allow us to infer the distribution of information before the IPO, the combination of results from our ma...

The venture capital industry is characterized by strong inter-organizational networks that have been shown to affect VC firm performance and the competitive supply of capital for entrepreneurs. We examine how VC firms’ observable resources are related to tie formation, and thus how networks facilitate the distribution and combination of resources across organizations. Unlike the social networks...

This result suggests that (1) ...

We identify causal effects by exploiting the effect of sovereign downgrades on corporate ratings that is due to sovereign ceiling policies followed by rating agencies. We find that sovereign downgrades lead to greater decreases in investment and leverage of firms that are at the sovereign rating b...

We analyze a model where investors (e.g., hedge funds) need to borrow from lenders with heterogeneous risk-exposures and risk-management motives. Investors may obtain advantageous terms of borrowing by disclosing their investment strategy, thereby revealing its correlation to the lender’s existing risk exposure. Investors risk being ‘‘front-run’’ by their lender if they disclose, however. We sh...
