Pricing models for American call and put options on futures contracts are derived herein. These models are used to investigate the efficiency of the market for options on Standard & Poor 500 and German Mark futures. The evidence presented here indicates that market prices for these options deviate substantially from their corresponding model prices. In addition, it is shown that a hedging strategy originated at prices that indicate a deviation of market from model is successful in translating the observed mispricing into excess profits after transactions costs. However, these net profits are eliminated if the origination of the strategy is delayed by one trade, or if bid-ask spreads are accounted for.

This paper investigates the efficiency of the market for foreign currency options with the help of a modified version of the Black-Scholes model. The evidence in the ex post tests is inconsistent with this hypothesis since we find a large number of opportunities for abnormal profits. A second set of tests is conducted on an ex ante basis to determine whether these profit opportunities exist even if the execution of the strategy is delayed by one day. The evidence from these tests provides more support for the hypothesis of market efficiency.

We analyze the impact of institutional and cultural differences on success in global venture capital (VC) investing. In both developed and emerging economies, superior legal rights (and enforcement) and better developed stock markets significantly enhance VC performance. Remarkably, cultural distance between countries of the portfolio company and its lead investor positively affects VC success. Further analysis reveals that cultural differences create incentives for rigorous ex ante screening, improving VC performance. Finally, local VC participation enhances success and mitigates foreign VCs’ “liability of foreignness,” albeit only in developed economies. Our findings follow from analyzing VC investments in nearly 10,000 companies across 30 countries.

We provide a new test of the informational efficiency of trading in stock options in the context of stock split announcements. These announcements tend to be associated with positive abnormal returns. Our traditional event study results show abnormal returns that are significantly lower for optioned than non-optioned stocks, whether traded on the NYSE, Amex, or Nasdaq. After controlling for market returns, capitalization, book-to-market ratio, and trading volume, we find that the abnormal returns are significantly lower for NYSE/Amex optioned than non-optioned stocks. Although the results for Nasdaq stocks are not as clear, the overall effects tend to be lower after optioning. These findings are consistent with the hypothesis that the prices of optioned stocks embody more information, diminishing the impact of the stock split announcement. They provide new evidence of the beneficial effects of options on their underlying stocks.
