摘要：In this paper we study high-dimensional time series that have the generalized dynamic factor structure. We develop a test of the null of k(0) factors against the alternative that the number of factors is larger than k(0) but no larger than k(1) > k(0) Our test statistic equals max(h0<= h) (gamma(k) - gamma(h+1))/(gamma(h+1) - gamma(h+2)), where gamma, is the ith largest eigen-value of the smoothed periodogram estimate of the spectral density matrix of data at a prespecified frequency. We descr...

摘要：This paper develops asymptotic optimality theory for statistical treatment rides in smooth parametric and semiparametric models Manski (2000, 2002, 2004) and Dehejia (2005) have argued that the problem of choosing treatments to maximize social welfare is distinct from the point estimation and hypothesis testing problems usually considered in the treatment effects literature, and advocate formal analysis of, decision procedures that map empirical data into treatment choices We develop large-sam...

摘要：A norm of 50-50 division appears to have considerable force in a wide range of economic environments. both In the real world and in the laboratory. Even in settings where one party unilaterally determines the allocation of a prize (the dictator game). many subjects voluntarily cede exactly half to another individual The hypothesis that people care about fairness does not by itself account for key experimental patterns. We consider :in alternative explanation, which adds the hypothesis that peo...

摘要：This paper uses control variables to identify and estimate models with nonseparable, multidimensional disturbances Triangular simultaneous equations models are considered, with instruments and disturbances that arc independent and it reduced form that is strictly monotonic in it scalar disturbance. Here it is shown that the conditional cumulative distribution function of the endogenous variable given the instruments is a control variable Also, for any control variable, identification results a...

摘要：This paper develops a method for inference in dynamic discrete choice models with serially correlated unobserved state variables. Estimation of these models involves computing high-dimensional integrals that are present in the solution to the dynamic program and in the likelihood function. First, the paper proposes it Bayesian Markov chain Monte Carlo estimation procedure that can handle the problem of multidimensional integration in the likelihood function. Second, the paper presents an effic...

摘要：We use a controlled experiment to explore whether there are gender differences in selecting into competitive environments across two distinct societies: the Maasai in Tanzania and the Khasi in India One Unique aspect Of these Societies is that the Maasai represent a textbook example of a patriarchal society, whereas the Khasi Lire matrilineal Similar to the extant evidence drawn front experiments executed in Western Cultures, Maasai men opt to compete at roughly twice the rate as Maasai women....
