We estimate the effects of unobserved skills on labor market outcomes by investigating a change in the distribution of unobserved skills. Among people with the same levels of observed skills such as education and work experience, there are still disparities in labor market outcomes. since...

We examine the effect of unobserved skills on labor market outcomes using a unique quasiexperiment generated by the 2012 education quota in Iran. By selecting different individuals for university programs, this policy changed the skill distribution of high school graduates entering the labor...

This paper presents a linear-city model where firms compete on price and levels of advertising, which affects the perceived utility of products. More cost efficient firms extend their advantage with more advertising, which leads to higher profits, if advertising is sufficiently effective. We...

Pre-averaging is a popular strategy for mitigating microstructure in high frequency financial data. As the term suggests, transaction or quote data are averaged over short time periods ranging from 30 seconds to five minutes, and the resulting averages approximate the efficient price process...

In this paper, we derive a new algebraic property of two scales estimation in high frequency data, under which the effect of sampling times is cancelled to high order. This is a particular robustness property of the two scales construction. In general, irregular, asynchronous, or endogenous...
