Managerial Stock Ownership and the Maturity Structure of Corporate Debt

This study documents that managerial stock ownership plays an important role in determining corporate debt maturity. Controlling for previously identified determinants of debt maturity and modeling leverage and debt maturity as jointly endogenous, we document a significant and robust inverse relation between managerial stock ownership and corporate debt maturity. We also show that managerial stock ownership influences the relation between credit quality and debt maturity and between growth opportunities and debt maturity.     

The effect of unfunded accumulated and projected pension obligations on governmental borrowing costs*

Abstract. Available evidence suggests that state and local government pension plans may be substantially underfunded. The capitalization of these unfunded obligations in borrowing costs is an important public policy issue, since noncapitalization may lead to the misallocation of credit and stimulate the provision of an inefficiently high level of current services. Prior research has relied largely on pension ratios as surrogates for unfunded liabilities and also appears to have made no attempt to distinguish between projected benefits and accumulated benefits. The Governmental Accounting Standards Board requires the disclosure of projected benefits and asserts that accumulated benefits severely understate the obligations of a governmental unit. The empirical evidence reported in this study suggests that, for state governments, unfunded projected liabilities provide no incremental information to the bond market over and above that already provided by unfunded accumulated liabilities. Résumé. Les données existantes laissent supposer que la capitalisation des régimes publics de pensions à l'échelle de l'État et à l'échelle locale pourrait être largement insuffisante. Le financement des obligations non capitalisées à même les coûts d'emprunt est une question de politique importante, puisque la non-capitalisation risque d'entraîner une mauvaise répartition des crédits et la fourniture d'un niveau de services actuel trop élevé. Dans les travaux de recherche précédents, l'on s'est appuyé en grande partie sur les ratios de retraite comme substituts dans le cas des dettes non capitalisées et l'on semble également n'avoir d'aucune façon tenté d'établir une distinction entre les prestations projetées et les prestations constituées. Le Governmental Accounting Standards Board exige la présentation des prestations prévues et affirme que le chiffre des prestations constituées sous-évalue de beaucoup les obligations gouvernementales. Les résultats concrets de la présente étude donnent à penser que pour les États, la communication des dettes prévues non capitalisées ne fournit au marché obligataire aucune information supplémentaire à la communication des dettes constituées non capitalisées.     

Systemic Risk and International Portfolio Choice

Returns on international equities are characterized by jumps; moreover, these jumps tend to occur at the same time across countries leading to systemic risk. We capture these stylized facts using a multivariate system of jump‐diffusion processes where the arrival of jumps is simultaneous across assets. We then determine an investor's optimal portfolio for this model of returns. Systemic risk has two effects: One, it reduces the gains from diversification and two, it penalizes investors for holding levered positions. We find that the loss resulting from diminished diversification is small, while that from holding very highly levered positions is large.     

An Examination of Uncovered Interest Rate Parity in Segmented International Commodity Markets

We examine the effect of segmented commodity markets on the relation between forward and future spot exchange rates in a dynamic economy. We calculate the slope coefficient in our theoretical economy from regressing exchange rate changes on forward premia. With reasonable parameter values, the slope coefficient is less than unity. However, even for extreme parameters the slope is not less than zero, as found in the data. A negative slope coefficient in a nominal version of the model requires the covariance between monetary shocks and relative output shocks to be significantly negative, in contrast to the covariance in the data.     

Equilibrium Portfolio Strategies in the Presence of Sentiment Risk and Excess Volatility

Our objective is to identify the trading strategy that would allow an investor to take advantage of "excessive" stock price volatility and "sentiment" fluctuations. We construct a general equilibrium "difference-of-opinion" model of sentiment in which there are two classes of agents, one of which is overconfident about a public signal, while still optimizing intertemporally. Overconfident investors overreact to the signal and introduce an additional risk factor causing stock prices to be excessively volatile. Consequently, rational investors choose a conservative portfolio; moreover, this portfolio depends not just on the current price divergence but also on their prediction about future sentiment and the speed of price convergence.     

ESTIMATING INCUMBENCY EFFECTS IN U.S. STATE LEGISLATURES: A QUASI‐EXPERIMENTAL STUDY

This paper estimates the incumbency effects in elections to the House of Representatives of 45 states in the United States using a quasi‐experimental research method, regression discontinuity design (RDD). This design isolates the causal effect of incumbency from other contemporaneous factors, such as candidate quality, by comparing incumbents and non‐incumbents in close contests. I find that incumbents in state legislative elections have a significant advantage, and this advantage serves as a strong barrier to re‐entry of challengers who had previously been defeated. However, the incumbency advantage estimated using the RDD is much smaller than are the estimates using existing methods, implying a significant selection bias in the latter.     

The Behavior of Option Price Around Large Block Transactions in the Underlying Security

This paper investigates the behavior of stock and option prices around block trades in stocks. The results indicate that for both up tick and downtick block trades the stock prices adjust within a fifteen minute period after the block trade. Moreover, for uptick blocks there is no evidence of any stock price reaction before the block trade. However, the adjustment of stock price for downtick blocks begins about fifteen minutes before the block trade. We also find that option price behavior differs considerably from stock price behavior. Specifically, our results suggest that options exhibit abnormal price behavior starting thirty minutes before the block and ending one hour after the block. The pattern is more pronounced for downtick blocks and for put options. We interpret this abnormal price behavior of options before the block trade as consistent with intermarket frontrunning.     

A General Equilibrium Model of International Portfolio Choice

We investigate, in a two-country general equilibrium model, whether a bias in consumption towards domestic goods will necessarily lead to a preference for domestic securities. We develop a model where investors are constrained to consume only from their domestic capital stock and where it is costly to transfer capital across countries. In this model, investors less risk averse than an investor with log utility bias their portfolios towards domestic assets. Investors more risk averse than log, however, prefer foreign assets. Thus, this model suggests that it is unlikely that the portfolios observed empirically can be explained by the high proportion of domestic goods in total consumption.     

The Exchange Rate in the Presence of Transaction Costs: Implications for Tests of Purchasing Power Parity

With transaction costs for trading goods, the nominal exchange rate moves within a band around the nominal purchasing power parity (PPP) value. We model the behavior of the band and of the exchange rate within the band. The model explains why there are below-unity slope coefficients in regression tests of PPP, and why these increase toward unity under hyperinflation or with low-frequency data. Our results are independent of the presence of nontraded goods in the economy.
