We estimate the causal effect of having full health insurance on health care expenditures. We take advantage of a unique quasi-experimental setup in which deductibles and co-payments were zero in a managed care plan, and non-zero in regular insurance, until a policy change forced all individuals...

We estimate the impact of external financial support on the labor supply of students during their tertiary education. Using a dynamic labor supply model and accounting for the endogeneity of income from private transfers, we find a significantly lower likelihood of being employed for transfer...

There is an ongoing discussion especially among political scientists and economists whether and how climate variability affects civil conflicts and wars in developing countries. Given the predicted climatic changes, several studies argue that increasing temperatures or decreasing precipitation...

We estimate the causal effect of having full health insurance on health care expenditures. We take advantage of a unique quasi-experimental setup in which deductibles and co- payments were zero in a managed care plan, and non-zero in regular insurance, until a policy change forced all...

As previously argued, the correlation between included and omitted regressors generally causes inconsistency of standard estimators for count data models. Using a specific residual function and suitable instruments, a consistent generalized method of moments estimator can be obtained under...

We discuss regression models for ordered responses, such as ratings of bonds, schooling attainment, or measures of subjective well-being. Commonly used models in this context are the ordered logit and ordered probit regression models. They are based on an underlying latent model with single...

This paper investigates the relationship between income satisfaction of adult children and their relative economic status, using data from the German Socio-Economic Panel and income rank as an indicator of status. The results show that children appear to compare their actual economic status with...
