Does the lack of international copyrights benefit or harm developing countries? I examine the effects of U.S. copyright piracy during a period when the U.S. was itself a developing country. U.S. statutes since 1790 protected the copyrights of American citizens, but until 1891 deemed the works of...

We show that a short-term (31 day) reading program, designed to provide age-appropriate reading material, to train teachers in their use, and to support teachers' initial efforts for about a month improves students' reading skills by 0.13 standard deviations. The effect is still present three...

We use book translations as a new measure of international idea flows and study the effects of Communism's collapse in Eastern Europe on these flows. Using novel data on 800,000 translations and difference-in-differences approaches, we show that while translations between Communist languages...

Choices are frequently made from lists where there is by necessity some ordering of options. In such situations individuals can exhibit both primacy bias towards the first option and recency bias towards the last option. We examine this phenomenon in a particularly interesting context: consumer...

This paper examines the effect of the Internet on markets in which match-quality is important, including an analysis of the market for used books. A model in which sellers of unusual objects wait for high-value buyers to arrive brings out match quality and competition effects through which...

We examine the effect of consumer reviews on relative sales of books on Amazon.com and BarnesandNoble.com. We find that 1) reviews are overwhelmingly positive at both sites, but there are more reviews and longer reviews at Amazon.com, 2) an improvement in a book's reviews leads to an increase in...

This paper provides a data-driven overview of the different online platforms that consumers use to search for books and booksellers, and documents how the use of these platforms is shifting over time. Our data suggest that, as a result of digitization, consumers are increasingly conducting...

The Catholic Church has been making saints for centuries, typically in a two-stage process featuring beatification and canonization. We analyze determinants of rates of beatification and canonization (for non-martyrs) over time and across six world regions. The research uses a recently assembled...

Trends in BMI values are estimated by centiles of the US adult population by birth cohorts 1886-1986 stratified by ethnicity. The highest centile increased by some 18 to 22 units in the course of the century while the lowest ones increased by merely 1 to 3 units. Hence, the BMI distribution...

The introduction of the direct reduction (fully-amortized) loan contract to the U.S. residential mortgage market is an important instance of financial innovation. We describe the adoption of this contract within the building and loan (B&L) industry beginning in the 1880s and culminating in the...
