3by Lee, Sokbae Published in Journal of econometrics (2007)“...This paper considers a linear triangular simultaneous equations model with conditional quantile restrictions. The paper adjusts for endogeneity by adopting a...”

4“...Multivalued treatment models have typically been studied under restrictive assumptions: ordered choice, and more recently, unordered monotonicity. We show how...”

5“...We develop a practical and novel method for inference on intersection bounds, namely bounds defined by either the infimum or supremum of a parametric or...”

6“...This paper presents new evidence that increases in college enrollment lead to a decline in the average quality of college graduates between 1960 and 2000,...”

8“...Data sets that are terabytes in size are increasingly common, but computer bottlenecks often frustrate a complete analysis of the data, and diminishing returns...”

9“...This paper studies inference of preference parameters in semiparametric discrete choice models when these parameters are not point-identified and the...”

10“...Economic theory often provides shape restrictions on functions of interest in applications, such as monotonicity, convexity, non-increasing (non-decreasing)...”

11“...We consider a variable selection problem for the prediction of binary outcomes. We study the best subset selection procedure by which the covariates are chosen...”

12“...We analyse cross‐country trends in several aspects of technological progress during 1980–2011 by examining the US patent citations data. Our estimation results...”

13“...This paper is concerned with developing uniform confidence bands for functions estimated nonparametrically with instrumental variables. We show that a sieve...”

15“...This paper extends the method of local instrumental variables developed by Heckman and Vytlacil [Heckman, J., Vytlacil E., 2005. Structural equations,...”
