This study examines the impact of European Central Bank (ECB) monetary policy surprises on economic uncertainty and investor risk aversion. We identify four factors using a high-frequency event-study approach. These factors measure surprises regarding the current setting of policy rates (Target), the bank’s future policy path (Forward Guidance), and quantitative easing (QE). The fourth factor reflects unexpected news about future macroeconomic conditions. Our main finding is that quantitative tightening surprises, proxied by positive QE surprises, increase economic uncertainty and investor risk aversion. Additionally, we document the significant response of key macroeconomic variables to these surprises.

Using a large sample of U.S. firms sponsoring defined benefit (DB) plans, we examine the impact of pension risk on firms’ cash management decisions. We document a positive curvilinear relationship between pension risk and cash holdings, finding that cash holdings by firms with high pension risk dramatically increase as their pension risk increases. However, this relationship appears only in the case of financially unconstrained firms, which suggests that the incentives to hedge against pension risk are only relevant when such risk is manageable. These results hold across different specifications, as well as when using several tests to address the potential endogeneity issue. We conduct multiple tests to examine alternative explanations of the findings, and we find that our results are mainly explained by the hedging incentives against pension risk and that the excess cash held by firms with higher pension risk is realized in a higher marginal value of cash.

I investigate the importance of local demand shocks on excess comovements and return predictability for 4560 twin-pairs of Exchange-Traded Funds (ETFs) from 15 country-pairs. The returns on ETFs traded in the same country comove excessively with one another. These comovements are stronger for funds with greater liquidity and more competitors in the local market. In contrast, comovements are not materially different among ETFs that are attractive to fundamental (factor) investors. A local measure of mispricing, based on price-deviations between ETFs and their foreign peers, strongly predicts ETF return reversals. Betting against local mispricing yields significant abnormal returns of up to 20 percent per year after trading costs.

Traditional stock option grant is the most common form of incentive pay in executive compensation. Applying a principal-agent analysis, we find this common practice suboptimal and firms are better off linking incentive pay to average stock prices. Among other benefits, averaging reduces volatility by about 42%, making the incentive pay more attractive to risk-averse executives. Holding the cost of the option grant to the firm constant, Asian stock options are more cost effective than traditional stock options and provide stronger incentives to increase stock price. More importantly, the improvement is achieved with little impact on the option grant’s risk incentives (after adjusting for option cost). Finally, averaging also improves the value and incentive effects of indexed stock options.

This paper studies the cross-currency and temporal variations in the random walk behavior in exchange rates. We characterize currencies with relatively large investment flows as investment intensive and conjecture that the more investment intensive a currency is, the closer its exchange rate adheres to random walk. Using 29 floating bilateral USD exchange rates, we find that the higher the investment intensity, the less likely it is to reject random walk and the smaller the deviation from random walk is. However, the effect of investment intensity is non-monotonic. Application of threshold models shows that after investment intensity reaches the estimated thresholds, the level of investment intensity has no further effect on the deviation from random walk. These findings help reconcile the previous conflicting results on the random walk in exchange rates by focusing on the effect of cross-currency and temporal variations in investment intensity.

Using a utility-maximization framework, I show that the incentive to increase stock price does not always increase as more options are granted. Keeping the total cost of his compensation fixed, granting more options creates greater incentives to increase stock price only if option wealth does not exceed a certain fraction of total wealth. Beyond this critical level, granting more options actually reduces incentive effects and becomes counterproductive. In addition, stock options also create incentive to reduce (increase) idiosyncratic (systematic) risk. These incentive effects are sensitive to the choice of exercise price.

This paper draws several important lessons from the Tequila Crisis of 1994 and 1995. The overriding lesson is that the dynamics of financial crises in emerging market countries differ from those in industrialized countries because institutional features of their debt markets differ. Several policy lessons for emerging market countries also emerge from the analysis: (1) pegged exchange-rate regimes are extremely dangerous, (2) strong prudential supervision of the banking system is critical for prevention of financial crises, (3) financial liberalization must be managed extremely carefully and (4) different policies are needed to promote recovery in emerging market countries than those that are applicable to industrialized countries.
