The Income-Achievement Gap and Adult Outcome Inequality
This paper discusses various methods for assessing group differences in academic achievement using only the ordinal content of achievement test scores. Researchers and policymakers frequently draw conclusions about achievement differences between various populations using methods that rely on the cardinal comparability of test scores. This paper shows that such methods can lead to erroneous conclusions in an important application: measuring changes over time in the achievement gap between youth from high- and low-income households. Commonly-employed, cardinal methods suggest that this ...

A Dummy Test of Identification in Models with Bunching
We propose a simple test of the main identification assumption in models where the treatment variable takes multiple values and has bunching. The test consists of adding an indicator of the bunching point to the estimation model and testing whether the coefficient of this indicator is zero. Although similar in spirit to the test in Caetano (2015), the dummy test has important practical advantages: it is more powerful at detecting endogeneity, and it also detects violations of the functional form assumption. The test does not require exclusion restrictions and can be implemented in many ...

How Do Children Spend Their Time? Time Use and Skill Development in the PSID
As income and wealth inequality have grown in the United States in recent decades, the large and growing differences in household expenditures on children from advantaged versus disadvantaged backgrounds have increasingly become a matter of public concern. High socioeconomic status (SES) households (those with high incomes and/or high levels of parental education) increasingly spend more money on physical goods (books, tuition, computers, etc.) and more time on "enrichment" activities such as homework, tutoring, reading, and extracurricular activities that are thought to directly foster ...

Should Children Do More Enrichment Activities? Leveraging Bunching to Correct for Endogeneity
We study the effects of enrichment activities such as reading, homework, and extracurricular lessons on children's cognitive and non-cognitive skills. We take into consideration that children forgo alternative activities, such as play and socializing, in order to spend time on enrichment. Our study controls for selection on unobservables using a novel approach which leverages the fact that many children spend zero hours per week on enrichment activities. At zero enrichment, confounders vary but enrichment does not, which gives us direct information about the effect of confounders on skills. ...

Measuring Aggregate Housing Wealth : New Insights from an Automated Valuation Model
We construct a new measure of aggregate U.S. housing wealth based on Zillow's Automated Valuation Model (AVM). AVMs offer advantages over other methods because they are based on recent market transaction prices, utilize large datasets which include property characteristics and local geographic variables, and are updated frequently with little lag. However, using Zillow's AVM to measure aggregate housing wealth requires overcoming several challenges related to the representativeness of the Zillow sample. We propose methods that address these challenges and generate a new estimate of aggregate ...
