This paper develops and implements semiparametric methods for estimating binary response (binary choice) models with continuous endogenous regressors. It extends existing results on semiparametric estimation in single-index binary response models to the case of endogenous regressors. It develops a control function approach to account for endogeneity in triangular and fully simultaneous binary response models. The proposed estimation method is applied to estimate the income effect in a labour market participation problem using a large micro data-set from the British Family Expenditure Survey. The semiparametric estimator is found to perform well, detecting a significant attenuation bias. The proposed estimator is contrasted to the corresponding probit and linear probability specifications.

The local Whittle (or Gaussian semiparametric) estimator of long range dependence, proposed by Künsch (1987) and analyzed by Robinson (1995a), has a relatively slow rate of convergence and a finite sample bias that can be large. In this paper, we generalize the local Whittle estimator to circumvent these problems. Instead of approximating the short-run component of the spectrum, ϕ(λ) , by a constant in a shrinking neighborhood of frequency zero, we approximate its logarithm by a polynomial. This leads to a "local polynomial Whittle" (LPW) estimator. We specify a data-dependent adaptive procedure that adjusts the degree of the polynomial to the smoothness of ϕ(λ) at zero and selects the bandwidth. The resulting "adaptive LPW" estimator is shown to achieve the optimal rate of convergence, which depends on the smoothness of ϕ(λ) at zero, up to a logarithmic factor.

Using detailed Japanese credit data, we test for the existence of a credit market hierarchy. Empirical tests indicate that firms with information problems are more likely to carry higher proportions of relationship loans from main banks than non-main banks, holding constant risk and control factors. We further examine credit specialization on the part of lenders by testing the relationship between client firms' information and risk characteristics and the concentration of loans obtained from depository institutions versus other financial institutions. However, no significant differences in information superiority between these two types of financial institutions are found. We conclude that our evidence supports the credit market hierarchy hypothesis for Japanese main banks in particular but not depository institutions in general.

We develop three empirical models to identify the impact of Community Reinvestment Act (CRA) agreements on the mortgage lending behavior of small banking institutions during the period 1990–1997. CRA agreements are pledges banking institutions make to extend levels of credit to targeted populations and are often used by institutions to reaffirm their commitment to the goals of the CRA. We hypothesize that CRA agreements increase the level of competition for mortgage loans in the targeted area, which in turn causes a reduction in the quantity of mortgage credit to be supplied by community banks. Consistent with the quantity hypothesis, the results show that CRA agreements are associated with less mortgage lending, including lending in lower-income communities (CRA lending) and in minority communities (minority lending), by small community lenders. Evidence does not support a second hypothesis – that community banks respond to the increased competition by providing credit to riskier individuals.

The returns to hedge funds and other alternative investments are often highly serially correlated. In this paper, we explore several sources of such serial correlation and show that the most likely explanation is illiquidity exposure and smoothed returns. We propose an econometric model of return smoothing and develop estimators for the smoothing profile as well as a smoothing-adjusted Sharpe ratio. For a sample of 908 hedge funds drawn from the TASS database, we show that our estimated smoothing coefficients vary considerably across hedge-fund style categories and may be a useful proxy for quantifying illiquidity exposure.

Abstract The actions of the federal government can have a profound impact on financial markets. As prominent participants in the government decision making process, U.S. Senators are likely to have knowledge of forthcoming government actions before the information becomes public. This could provide them with an informational advantage over other investors. We test for abnormal returns from the common stock investments of members of the U.S. Senate during the period 1993–1998. We document that a portfolio that mimics the purchases of U.S. Senators beats the market by 85 basis points per month, while a portfolio that mimics the sales of Senators lags the market by 12 basis points per month. The large difference in the returns of stocks bought and sold (nearly one percentage point per month) is economically large and reliably positive.

This paper measures the impact of an outbreak of pediatric leukemia on local housing values. A model of location choice is used to describe conditions under which the gradient of the hedonic price function with respect to pediatric leukemia risk is equal to household marginal willingness to pay to avoid risk. This equalizing differential is estimated using property-level sales records from a county in Nevada where residents recently experienced a severe increase in pediatric leukemia. Housing prices are compared before and after the increase with a nearby county acting as a control group. The variation in health risk over time makes it possible to control for unobserved differences across locations. In addition, because many houses were sold repeatedly during the sample period it is possible to control for property-specific heterogeneity. The results indicate that housing values decreased 15.6 percent during the period of maximum risk. Results are similar for different measures of risk and across houses of different sizes. Using lifetime estimates of risk derived from a Bayesian learning process the results imply that the statistical value of pediatric leukemia is $5.6 million. These estimates provide some of the first market-based estimates of the value of health for children.

We study the long-run sustainability of reputations in games with imperfect public monitoring. It is impossible to maintain a permanent reputation for playing a strategy that does not play an equilibrium of the game without uncertainty about types. Thus, a player cannot indefinitely sustain a reputation for noncredible behavior in the presence of imperfect monitoring.

Abstract We investigate the pricing of 4,989 equity IPOs with offer dates between 1981 and 2000. Approximately three-fourths of these IPOs have integer offer prices. Average initial returns for IPOs with integer offer prices are significantly higher (24.5%) than those priced on the fraction of the dollar (8.1%). This result is robust through time and after conditioning for other effects known to influence initial returns. We hypothesize that integer vs. fractional dollar IPOs are the result of negotiations between the issuing firm and underwriter. Under this negotiation hypothesis, the frequency of integer pricing should be an increasing function of the offer price and the degree of uncertainty surrounding the value of the firm. Empirical evidence, supportive of the negotiation hypothesis, is presented.
