We provide new insights regarding the finding that Medicaid increased emergency department (ED) use from the Oregon experiment. We find meaningful heterogeneous impacts of Medicaid on ED use using causal machine learning methods. The treatment effect distribution is widely dispersed, and the...

We investigate the effect of education Conditional Cash Transfer programs (CCTs) on teenage pregnancy. Our main concern is with how the size and sign of the effect may depend on the design of the program. Using a simple model we show that an education CCT that conditions renewal on school...

Using specific panel data of German welfare benefit recipients, we investigate the nonpecuniary life satisfaction effects of in-work benefits. Our empirical strategy combines difference-in-difference designs with synthetic control groups to analyze transitions of workers between unemployment,...

Private information is at the heart of many economic activities. For decades, economists have assumed that individuals are willing to misreport private information if this maximizes their material payoff. We combine data from 72 experimental studies in economics, psychology and sociology, and...

We theoretically analyse the effects of sick pay and employees' health on collective bargaining, assuming that individuals determine absence optimally. If sick pay is set by the government and not paid for by firms, it induces the trade union to lower wages. This mitigates the positive impact on...

Many competitive health insurance markets adjust payments to participating health plans according to their enrollees' risk - including based on diagnostic information. We investigate responses of German health plans to the introduction of morbidity-based risk adjustment in the Statutory Health...

This paper investigates the impact of the Affordable Care Act’s (ACA’s) dependent coverage mandate on health insurance coverage rates and health care utilization among young adults. Using data from the Medical Panel Expenditure Survey, I exploit the discontinuity in health insurance coverage...

Employer-provided health insurance may restrict job mobility, resulting in “job lock.” Previous research on job lock finds mixed results using several methodologies. We take a new approach to examine job-lock by exploiting the discontinuity created at age 65 through the qualification for...

The paper derives the optimal carbon tax in closed-form from an integrated assessment of climate change. The formula shows how carbon, temperature, and economic dynamics quantify the optimal mitigation effort. The model's descriptive power is comparable to numeric models used in policy advising....

This paper investigates the relationship between health insurance coverage and risky health behaviors among young adults using the confidential version of the National Longitudinal Survey of Youth, 1997 Cohort (NLSY97). Before the Affordable Care Act required all employers to provide health...
