This paper develops the adaptive elastic net GMM estimator in large dimensional models with many possibly invalid moment conditions, where both the number of structural parameters and the number of moment conditions may increase with the sample size. The basic idea is to conduct the standard GMM...

This policy brief contains a formal consideration of ideas discussed during a presentation to the 2012 Syracuse Seminar on Aging. Like most briefs, it will appeal to policy makers and academics craving detailed demographic, fiscal and policy data. This brief focuses on limitations faced by...

In this brief we argue that welfare participation is more sensitive to economic conditions than previously believed. Why? Prior research focused on short-term economic fluctuations and ignored differences between high- and low-skilled workers. As welfare is long-term (i.e., permanent) it makes...

In this brief we take a closer look at the mechanisms used to distribute resources across public schools. We first present what we know about the current distribution of educational resources within New York City and other large city districts. Then we discuss current efforts to promote greater...

This paper presents initial findings on the economic impact of the Earned Income Tax Credit (EITC) based on a sample of Chicago area households that filed tax returns in the spring of 1998. Respondents reported on their detailed use of the funds to pay bills, purchase new items, or save. Asset...

This paper processes copula-based tests for testing cross-sectional independence of panel models.

Our paper utilizes variation across the 50 U.S. states to examine the relationship between public expenditures on children and child outcomes. We find that public expenditures on children are related to better child outcomes across a wide range of indicators, including measures of child...

This paper makes two contributions to the empirical literature on agglomeration economies. First, the paper uses a unique and rich database in conjunction with mapping software to measure the geographic extent of agglomerative externalities. Previous papers have been forced to assume that...

This paper develops a novel asymptotic theory for panel models with common shocks. We assume that contemporaneous correlation can be generated by both the presence of common regressors among units and weak spatial dependence among the error terms. Several characteristics of the panel are...

This paper investigates the effect of entrepreneurs' pesonal income tax situations on the growth rate of their enterprises. We analyze the personal income tax returns of a large number of sole proprietors before and after the Tax Reform Act of 1986 and determine how the substantial reductions in...
