People are heterogenous in the skills by which they turn eort into output. A central question in normative public economics is how to redistribute resources from more- to less-skilled individuals eciently. In addition to income taxation, this paper considers another policy tool of redistribution...

This paper documents the variation in economic characteristics across voyages during the trans-Atlantic slave trade. Dispersion in output, measured as slaves disembarked, is highest across Portuguese voyages, lower across French voyages, and lowest across British voyages. We use a structural...

We construct a structural model that allows us to jointly estimate the demand for smartphones and paid apps using a Bayesian approach. Our data comes from more than 500 college students in Hong Kong and Shanghai. We find that the moral cost rather than the monetary cost of jailbreaking...

Music piracy is a double-edged sword for the music industry. On the one hand, it hurts record sales. On the other hand, it increases sales of its complements. To quantify the effect of music piracy, I construct a unique survey data set and use a Bayesian method to estimate the demand for music...

Hollywood blockbusters are usually released in the U.S. before other foreign markets. The release gaps have declined significantly over time and varied greatly across countries. While movie piracy has been suggested as an important determinant for the release gap decision of distributors, theory...

Polygyny rates are higher in western Africa than in eastern Africa. The African slave trades help explain this difference. More male slaves were exported in the transatlantic slave trades from western Africa, while more female slaves were exported in the Indian Ocean slave trades from eastern...

Do homeowners prefer living in an area with a more equal distribution of income? We answer this question by estimating a semi-parametric hedonic pricing model for about 90,000 housing units transacted in Hong Kong between 2005 and 2006. We first identify a hedonic price function by locally...

Using a unique conjoint data set drawn from 281 college students in Hong Kong, I estimate a random-coefficient discrete choice demand system for Microsoft Office from legal and various illegal sources. Counterfactual results show two things. First, most students would switch to Internet piracy...

Software piracy remains rampant despite the successful measures the Hong Kong government has taken to eradicate street piracy. This is because most people prefer substituting a counterfeit copy of a software CD (street piracy) with an illegal download of the software (Internet piracy). To...
