We derive the efficiency loss from using grouped data to estimate coefficients of variables that vary across groups but not individuals within a group (e.g., state unemployment rates) when micro data are unavailable on the dependent variable. We present an empirical example of our theoretical...

Using spectral regression and exact maximum likelihood methods, we test for long memory dynamics in the traded goods prices for the G7 countries, as measured in their import and export price indices. Significant and robust evidence of fractional dynamics with long memory features is found in...

This paper provides an explicit welfare basis for evaluating economic mobility. Our social welfare function can be seen as a natural dynamic extension of the static social welfare function presented in Atkinson and Bourguignon (1982). Unlike Atkinson and Bourguignon, we use social preferences a...

This paper analyzes a model with many homogeneous agents, whose effort can be allocated to two tasks. One task produces a public good that is an important input for the production of the final output. The other task only affects the agent's own output. We show that, when the public input and the...

Wage cuts are often presumed to reflect an adverse change in economic constraints. However, several theoretical models have shown they can be a form of investment in future wage growth. This paper provides empirical evidence of the latter by explicitly modeling the worker's job choice when the...

We construct an agency model in which the planner (agent) makes project starting and termination decisions on behalf of the state (principal) to reflect the practice of socialist economies. The model shows that asymmetric information between the state and the planner regarding the quality of...
