摘要:This article studies estimation of a conditional moment restriction model with the seminonparametric maximum likelihood approach proposed by Gallant and Nychka (Econometrica 55 (March 1987), 363-90). Under some sufficient conditions, we show that the estimator of the finite dimensional parameter theta is asymptotically normally distributed and attains the semiparametric efficiency bound and that the estimator of the density function is consistent under L-2 norm. Some results on the convergence...

摘要:We construct a model of the housing market in which agents differ in their flow values while searching. Agents enter the market relaxed (with high flow values) but move to a desperate state (low flow values) at a Poisson rate if they have not already transacted. We characterize the equilibrium steady-state matching pattern and the joint distribution of price and time to sale (for sellers). The expected price conditional on time to sale falls with time spent on the market, whereas the condition...

摘要:American students study harder in college than in high school, whereas East Asian students study harder in high school than in college. This article proposes a signaling explanation. Signaling may occur over time both in high school and in college, and societies may differ in the timing of signaling. Students work harder in the signaling stage determined by the society as a whole. A testable implication is that high ability workers in East Asia are more concentrated among a few colleges than t...

摘要:A particularly challenging use of decision-theoretic models in economics is to forecast the impact of large changes in the environment. The problem we explore in this article is how to gain confidence in a model's ability to predict the impact of such large changes. We show that an approach to validation and model selection that includes the choice of a '' nonrandom holdout sample,'' a sample that differs significantly from the estimation sample along the policy dimension that the model is mea...

摘要:I present nonparametric methods to identify and estimate the biases associated with response errors. When applied to survey data, these methods can be used to analyze how observable and unobservable characteristics of the respondent, and characteristics of the design of the survey, affect errors in the responses. This provides a method to correct the biases that those errors generate, by using the estimated response errors to '' undo '' those biases. The results are useful also to design bette...

摘要:This article shows that state control of some industries may have contributed to the increase in European unemployment from the 1970s to the early 1990s. We develop a simple two-sector model, one privately run and one publicly run, that has risk-averse workers directing their search into one of the sectors. Assuming that the privately run sector is less able to insure its employees against uncertainty, we show that aggregate unemployment in this economy increases in response to an increase in ...

摘要:Continuous time models in the theory of real options give explicit formulas for optimal exercise strategies when options are simple and the price of an underlying asset follows a geometric Brownian motion. This article suggests a general, computationally simple approach to real options in discrete time. Explicit formulas are derived even for embedded options. Discrete time processes reflect the scarcity of observations in the data, and may account for fat tails and skewness of probability dist...

摘要:This article extends the pairwise difference estimators for various semilinear limited dependent variable models proposed by Honore and Powell (Identification and Inference in Econometric Models. Essays in Honor of Thomas Rothenberg Cambridge: Cambridge University Press, 2005) to permit the regressor appearing in the nonparametric component to itself depend upon a conditional expectation that is nonparametrically estimated. This permits the estimation approach to be applied to nonlinear models...

摘要:Current methods of estimating the random coefficients logit model employ simulations of the distribution of the taste parameters through pseudo-random sequences. These methods suffer from difficulties in estimating correlations between parameters and computational limitations such as the curse of dimensionality. This article provides a solution to these problems by approximating the integral expression of the expected choice probability using a multivariate extension of the Laplace approximati...

摘要:We develop a consumer-level model of vehicle choice to shed light on the erosion of the U.S. automobile manufacturers' market share during the past decade. We examine the influence of vehicle attributes, brand loyalty, product line characteristics, and dealerships. We find that nearly all of the loss in market share for U.S. manufacturers can be explained by changes in basic vehicle attributes, namely: price, size, power, operating cost, transmission type, reliability, and body type. U.S. manu...
