Estimation of panel data regression models with two-sided censoring or truncation
This paper constructs estimators for panel data regression models with individual specific heterogeneity and two-sided censoring and truncation. Following Powell (1986) the estimation strategy is based on moment conditions constructed from re-censored or re-truncated residuals. While these moment conditions do not identify the parameter of interest, they can be used to motivate objective functions that do. We apply one of the estimators to study the effect of a Danish tax reform on household portfolio choice. The idea behind the estimators can also be used in a cross sectional setting.

Explaining the decline in the U.S. labor force participation rate
The authors conclude that just under half of the post-1999 decline in the U.S. labor force participation rate, or LFPR (the proportion of the working-age population that is employed or unemployed and seeking work), can be explained by long-running demographic patterns, such as the retirement of baby boomers. These patterns are expected to continue, offsetting LFPR improvements due to economic recovery.

Credit Score Doctors
We study how the existence of cutoffs in credit scores affects the behavior of homebuyers. Borrowers are more likely to purchase houses after their credit scores cross over a cutoff to qualify them for a higher credit score bin. However, the credit accounts of these individuals (crossover group) are more likely to become delinquent within four years following home purchases than the accounts of those who had stayed in the same bin (non-crossover group). The effect is not only concentrated in subprime bins, but in other bins as well. It is neither limited to pre-crisis period nor curtailed by ...

Simultaneity in Binary Outcome Models with an Application to Employment for Couples
Two of Peter Schmidt’s many contributions to econometrics have been to introduce a simultaneous logit model for bivariate binary outcomes and to study estimation of dynamic linear fixed effects panel data models using short panels. In this paper, we study a dynamic panel data version of the bivariate model introduced in Schmidt and Strauss (1975) that allows for lagged dependent variables and fixed effects as in Ahn and Schmidt (1995). We combine a conditional likelihood approach with a method of moments approach to obtain an estimation strategy for the resulting model. We apply this ...

Sample Selection Models Without Exclusion Restrictions: Parameter Heterogeneity and Partial Identification
This paper studies semiparametric versions of the classical sample selection model (Heckman (1976, 1979)) without exclusion restrictions. We extend the analysis in Honoré and Hu (2020) by allowing for parameter heterogeneity and derive implications of this model. We also consider models that allow for heteroskedasticity and briefly discuss other extensions. The key ideas are illustrated in a simple wage regression for females. We find that the derived implications of a semiparametric version of Heckman's classical sample selection model are consistent with the data for women with no college ...

How much of the decline in unemployment is due to the exhaustion of unemployment benefits?
Prior studies have examined the impact of extended unemployment insurance (UI) benefits on the rise in the unemployment rate in this recession and early recovery. We use real-time microdata from the Bureau of Labor Statistics? Current Population Survey (CPS) to examine whether there has been a reverse effect recently as benefits have been exhausted. We find that if UI benefits had lasted indefinitely, the unemployment rate would have been cumulatively about 0.1 to 0.3 percentage points higher between October 2009 and January 2011, which represents about 10% to 25% of the decline in the actual ...

Easy Bootstrap-Like Estimation of Asymptotic Variances
The bootstrap is a convenient tool for calculating standard errors of the parameter estimates of complicated econometric models. Unfortunately, the bootstrap can be very time-consuming. In a recent paper, Honor and Hu (2017), we propose a ?Poor (Wo)man's Bootstrap? based on one-dimensional estimators. In this paper, we propose a modified, simpler method and illustrate its potential for estimating asymptotic variances.

Simpler Bootstrap Estimation of the Asymptotic Variance of U-statistic Based Estimators
The bootstrap is a popular and useful tool for estimating the asymptotic variance of complicated estimators. Ironically, the fact that the estimators are complicated can make the standard bootstrap computationally burdensome because it requires repeated re-calculation of the estimator. In Honor and Hu (2015), we propose a computationally simpler bootstrap procedure based on repeated re-calculation of one-dimensional estimators. The applicability of that approach is quite general. In this paper, we propose an alternative method which is specific to extremum estimators based on U-statistics. ...

Changing Labor Force Composition and the Natural Rate of Unemployment
This article discusses why changes in the composition of the labor force may have lowered the natural (or trend) rate of unemployment?the unemployment rate that would prevail in an economy making full use of its productive resources?to 5 percent or less. A lower natural rate may help explain why wage inflation and price inflation remain low despite actual unemployment recently reaching 5.5 percent?a figure only slightly above prominent estimates of the natural rate, such as that of the Congressional Budget Office (CBO). Demographic and other changes should continue to lower the natural rate ...

Do labor market activities help predict inflation?
The authors conduct an empirical analysis of the role of labor market activities in inflation and conclude that wage growth is not very informative for predicting price inflation. But price inflation does seem to help predict wage growth.
