This paper investigates the forecasting accuracy of bankruptcy hazard rate models for U.S. companies over the time period 1962–1999 using both yearly and monthly observation intervals. The contribution of this paper is multiple-fold. One, using an expanded bankruptcy database we validate the superior forecasting performance of Shumway's (2001) model as opposed to Altman (1968) and Zmijewski (1984). Two, we demonstrate the importance of including industry effects in hazard rate estimation. Industry groupings are shown to significantly affect both the intercept and slope coefficients in the forecasting equations. Three, we extend the hazard rate model to apply to financial firms and monthly observation intervals. Due to data limitations, most of the existing literature employs only yearly observations. We show that bankruptcy prediction is markedly improved using monthly observation intervals. Fourth, consistent with the notion of market efficiency with respect to publicly available information, we demonstrate that accounting variables add little predictive power when market variables are already included in the bankruptcy model.

Mergers and acquisitions improve market efficiency by capturing synergies between firms. But takeovers also impose externalities (both positive and negative) on the remaining firms in the industry. This paper describes a new equilibrium concept designed to explain and predict takeovers in this setting. We experimentally compare the new equilibrium concept to that of competing con-cepts in situations without and with externalities. Moreover, we examine the predicted dynamics of takeovers and outcome implications of those dynamics. Our experimental results support the predictions of the new equilibrium concept and provide implications for further empirical tests. 1.

The paper analyses the relationship between deposit insurance, debt-holder monitoring, and risk taking. In a stylised banking model we show that deposit insurance may reduce moral hazard, if deposit insurance credibly leaves out non-deposit creditors. Testing the model using EU bank level data yields evidence consistent with the model, suggesting that explicit deposit insurance may serve as a commitment device to limit the safety net and permit monitoring by uninsured subordinated debt holders. We further find that credible limits to the safety net reduce risk taking of smaller banks with low charter values and sizeable subordinated debt shares only. However, we also find that the introduction of explicit deposit insurance tends to increase the share of insured deposits in banks' liabilities.

Participants in 401(k) retirement plans violate the basic principle of diversification by investing significant fractions of their savings in their employers' equity. This paper characterizes investors' active changes to their company stock investment over time by analyzing new inflows and transfers. The average investor seems to base active changes on salient information, paying attention to past returns, volatility, and business performance. Past returns, over a three-year horizon, predict higher inflow allocations and transfers, whereas volatility and business performance only have a weak effect. The sensitivity to past returns is asymmetric, with investors reacting more strongly to positive and above-S&P500 returns.

I conduct a time-series analysis of corporate payout policies that accounts for the dynamic nature of these decisions and for the interaction among investment decisions and payout policies. The estimation is done with a VAR model of investments, earnings, total payout, and the split of the total payout between dividends and share repurchases. I control for changes in the legal treatment of share repurchases in 1982 and for changes in the relative taxation of dividends and capital gains. I find that: (i) an increase in the taxation of capital gains relative to dividends shifts the split of total payout away from share repurchase and toward dividends; (ii) corporate investment decisions lead payout policies and not the other way around; (iii) increases in corporate total payout are associated with long-term subsequent increases in earnings; (iv) changes in the composition of corporate payout away from share repurchases and toward dividends are associated with subsequent increases in earnings.

We examine a set of equity index-linked bonds that provide the same payoff as an investment in an equity index, but are relatively illiquid. We demonstrate that these securities sell at a discount relative to their underlying value and hence have higher expected returns. We show that this apparent mispricing can be attributed to the illiquidity of the bonds. Trading costs for equity-linked bonds, as measured by bid-ask spreads, are free of any asymmetric information or inventory holding cost component; hence the only illiquidity component left is clearing costs. This study shows that, even in the absence of asymmetric information and inventory holding costs, illiquidity depresses asset prices and therefore increases expected security returns. Using an ex ante measure of the expected return premium due to illiquidity, we link the time-series variation in the illiquidity premium to security-specific attributes related to their marketability. We show that liquidity risk has a systematic component, and relate this market-wide factor to a number of macroeconomic variables that have previously been shown to be related to illiquidity.

We study opening prices set simultaneously for German and French stocks in Frankfurt and Paris. In our model investors and traders based in the same country as the firm have better information on its value than foreign traders. Our theory implies that prices set on the domestic market differ from (and are more informationally efficient than) prices set on the foreign market. Empirically, we find significant price discrepancies between home and foreign prices, consistent with lack of integration of international financial markets. For German stocks, home prices are found to be informationally more efficient than foreign prices. The informational efficiency of French stock prices is comparable in the two markets when Frankfurt traders can observe Paris preopening prices before the opening.

We analyze the empirical predictions of ambiguity aversion in intertemporal heterogenous agents economies. We examine equilibria for two tract able wealth–homothetic settings of ambiguity aversion in continuous time. Each setting is motivated by a different robust control optimization problem. We show that ambiguity aversion affects optimal portfolios in a way that is similar to an increase in risk aversion. A distinct property of our second setting of ambiguity aversion is that this increase is state dependent, highly pronounced at moderate portfolio exposures and reduces equity-market participation. In general equilibrium, ambiguity aversion raises the equity premium and lowers interest rates. A distinct feature of our second setting of ambiguity aversion is that the equity premium part due to ambiguity aversion dominates when volatility is low.
