Using Korean data, this study investigates whether son-favoring ideas or the preference for sons affect fertility decisions. Son-favoring fertility behavior in Korea is of interest because the sex ratio at birth has recovered to a natural level after having been very skewed. To isolate the effects of the preference for sons from the effects of the surrounding environment, we compare the fertility behavior of individuals living in the same region but who were born in different regions or years. E

Mulligan and Rubinstein (2008) (MR) argued that changing selection of working females on unobservable characteristics, from negative in the 1970s to positive in the 1990s, accounted for nearly the entire closing of the gender wage gap. We argue that their female wage equation estimates are inconsistent. Correcting this error substantially weakens the role of the rising selection bias (39 % versus 78 %) and strengthens the contribution of declining discrimination (42 % versus 7 %). Our findings r

This paper develops a method that accounts for non-ignorable sample attrition in the presence of population attrition for use with a non-representative panel sample. The method is applied to obtain attrition-correcting weights for the native and immigrant samples in the matched Current Population Survey (CPS). Of the two samples, the immigrant sample suffers from sample attrition due to changes in residence as well as population attrition caused by selective return migration. When there is popul

This paper provides a human capital theory‐based explanation for the presence of a permanent component in earnings levels as well as individual heterogeneity in earnings slopes. We incorporate uncertainty about the future rental rates of human capital into a life‐cycle human capital investment model and obtain an earnings equation implied by the solution to the worker's optimal investment decision. While heterogeneous growth stems from individual heterogeneity in the ability of human capital pro

Abstract This paper presents new evidence on whether foreign-born workers assimilate. While the existing literature focuses on the convergence/divergence of average wages, this study extends the analysis to the distribution of wages by looking at wage mobility. We measure the foreign-native gap in year-to-year transition probabilities from one decile group to another of a wage distribution, where the deciles are determined by native samples. Our results, based on the Current Population Survey fo

Previous papers on testing for statistical discrimination and employer learning require variables that employers do not observe directly, but are observed by researchers or data on employer-provided performance measures. This paper develops a test that does not rely on these speci…c variables. The proposed test can be performed with individual-level cross-section data on employment status, experience, and some variables on which discrimination is based, such as race, gender, and education. This

This paper presents a new test for the family investment hypothesis (FIH). We show that a simple two-period labor supply model produces testable implications on the work hours and occupational choices for married women. In credit-constrained households, married women …nancially support their families by working in dead-end jobs that do not necessarily require much skill. The support decreases as their families overcome credit-constraints. We analyze the occupation choices for married women using

This paper investigates the effects of supplementary education during high school years, such as private tutoring and studying alone, on post-school labor market performance. Using a representative longitudinal sample of Korean high school seniors in 2004, we find that studying alone has a positive effect on wages after controlling for college entrance exam scores, but private tutoring does not. This implies that private tutoring does not directly affect earning potential, although it may do so

Tests of statistical discrimination require evaluation records provided by employers or variables that employers do not observe directly but are observed by researchers. As such variables are difficult to obtain, this paper develops a strategy that uses variables available in usual data sets. This paper derives testable implications for statistical discrimination by exploiting the heterogeneity in employer learning processes. Evidence from analysis using the March Current Population Survey for 1

The output of one industry can influence other industries beyond its immediate supply chains. When regional employment expands, local demand for goods and services rises, stimulating additional production and job creation. Because services are locally oriented, growth in manufacturing employment can boost regional service employment. This study empirically analyzes data at the si and gun levels using the Survey on Establishments’ Labor Conditions from the Korean Statistical Information Service.

본고는 소수집단 우대정책이 작동하는 원리에 대해 Fryer and Loury(2005)의 내용을 바탕으로 우리나라 상황을 포함하여 객관적이고 분석적인 정보를 제공한다. 소수집단 우대정책은 의도한 목표를 달성하기도 하지만, 목표를 달성하는 데 효과적이지 않을 수 있으며, 심지어 의도하지 않은 부정적 결과를 초래하기도 한다. 기회균등만으로 차별없는 사회에 도달하는 것이 쉽지 않다면 우대정책을 고려할 수 있을 것이다. 그러나 급진적인 할당제의 도입은생산성 격차를 고착시키는 등 부작용이 클 수 있으므로 긴 시간을 두고 점진적으로 시행하여야 한다. 또한 우대정책을 고용 단계에 시행하면 비용을 타인에게 전가시킬 가능성이 있으므로 가급적 교육 단계에서 시행하여야 한다. 한편, 집단중립적 정책이나 목표제는 통상적인소수집단 우대정책과 다르지 않으며, 우대정책의 결과 다수집단이 입는 피해는 생각보다 크지 않을 수 있고, 우대의 대상인 소수집단도 피해자가 될 수 있다

Abstract This article investigates the time to first birth, treating coresidence with hus-band’s parents and labor supply as endogenous and using representative data on Taiwanese married women born during 1933–1968. We use a full-information maximum likelihood estimator for a duration model with endogenous binary variables. Results controlling for endogeneity suggest that both coresidence and working are associated with a delay in childbearing, reversing the effect of coresidence on the timing o
