July 2020The Microeconomics of Cryptocurrencies
with Guillaume Haeringer, Joshua S. Gans, Neil Gandal: w27477
Since its launch in 2009 much has been written about Bitcoin, cryptocurrencies and blockchains. While the discussions initially took place mostly on blogs and other popular media, we now are witnessing the emergence of a growing body of rigorous academic research on these topics. By the nature of the phenomenon analyzed, this research spans many academic disciplines including macroeconomics, law and economics and computer science. This survey focuses on the microeconomics of cryptocurrencies themselves. What drives their supply, demand, trading price and competition amongst them. This literature has been emerging over the past decade and the purpose of this paper is to summarize its main findings so as to establish a base upon which future research can be conducted.
February 2020Were Jews in Interwar Poland More Educated?
with Ran Abramitzky: w26763
In the context of interwar Poland, we find that Jews tended to be more literate than non Jews, but show that this finding is driven by a composition effect. In particular, most Jews lived in cities and most non-Jews lived in rural areas, and people in cities were more educated than people in villages regardless of their religion. The case of interwar Poland illustrates that the Jewish relative education advantage depends on the historical and institutional contexts.
April 2015Some Economics of Private Digital Currency
with Joshua S. Gans
in Economic Analysis of the Digital Economy, Avi Goldfarb, Shane M. Greenstein, and Catherine E. Tucker, editors
This paper reviews some recent developments in digital currency, focusing on platform-sponsored currencies such as Facebook Credits. We develop a model of platform management in which platform currency offers "enhancements" to users who spend time on the platform. Users allocate time between earning money outside of the platform and using the platform. The platform can equip its currency in different attributes and limitations, with the goal of maximizing profit. We show that limiting functionality of currency (e.g., prohibiting transferability) may increase usage on the platform. But depending on the source of the revenue, different attributes of the currency are optimal. We also find that it will not likely be profitable for such currencies to expand to become fully functional competitor...
