摘要：The act of choosing can have particular relevance in maximizing behavior for at least two distinct reasons: (1) process significance (preferences may be sensitive to the choice process, including the identity of the chooser), and (2) decisional inescapability (choices may have to be made whether or not the judgemental process has been completed). The general approach of maximizing behavior can - appropriately formulated - accommodate both concerns, but the regularities of choice behavior assum...

摘要：This paper presents a procedure for analyzing a model in which the parameter vector has two parts: a finite-dimensional component theta and a nonparametric component lambda. The procedure does not require parametric modeling of lambda but assumes that the true density of the data satisfies an index restriction. The idea is to construct a parametric model passing through the true model and to estimate theta by setting the score for the parametric model to zero. The score is estimated nonparamet...

摘要：This paper develops a search-theoretic model of technological change that accounts for some puzzling trends in industrial research, patenting, and productivity growth. In the model, researchers sample from probability distributions of potential new production techniques. Past research generates a technological frontier representing the best techniques for producing each good in the economy. Technological breakthroughs, resulting in patents, become increasingly hard to find as the technological...

摘要：The concept of adaptively rational equilibrium (A.R.E.) is introduced. Agents adapt their beliefs over time by choosing from a finite set of different predictor or expectations functions. Each predictor is a function of past observations and has a performance or fitness measure which is publicly available. Agents make a rational choice concerning the predictors based upon their past performance. This results in a dynamics across predictor choice which is coupled to the equilibrium dynamics of ...

摘要：We consider the problem of estimation in a panel data sample selection model, where both the selection and the regression equation of interest contain unobservable individual-specific effects. We propose a two-step estimation procedure, which ''differences out'' both the sample selection effect and the unobservable individual effect from the equation of interest. In the first step, the unknown coefficients of the ''selection'' equation are consistently estimated. The estimates are then used to...
