We investigate the speed at which clusters of invention for a technology migrate spatially following breakthrough inventions. We identify breakthrough inventions as the top one percent of US inventions for a technology during 1975-1984 in terms of subsequent citations. Patenting growth is...

This paper aims to provide a swift tour of the economic issues presented by vouchers and thus to fill an apparent gap in the literature for a basic survey of the subject. Among the issues it considers are: factors determining a voucher's cash-equivalence; reasons (such as paternalism,...

This paper reports on the current status of the microeconomic research on labor supply behavior. The purpose is to direct attention to microeconomic research that may be helpful in the continuing evaluation of aggregate models designed to explain the dynamic behavior of wages, employment and...

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...

This chapter provides a selective review of some contemporary approaches to program evaluation. One motivation for our review is the recent emergence and increasing use of a particular kind of "program" in applied microeconomic research, the so-called Regression Discontinuity (RD) Design of...

A number of market failures have been associated with R&D investments and significant amounts of public money have been spent on programs to stimulate innovative activities. In this paper, we review some recent microeconomic studies evaluating effects of government sponsored commercial R&D. We...

Inattention is a central, unifying theme for much of behavioral economics. It permeates such disparate fields as microeconomics, macroeconomics, finance, public economics, and industrial organization. It enables us to think in a rather consistent way about behavioral biases, speculate about...

An emerging consensus on the future of macroeconomics views the incorporation of a role for financial intermediation, labor market frictions, and household heterogeneity in the presence of uninsurable unemployment risk as key needed extensions to the benchmark macro framework. I argue that this...

We identify three separate stages in the post-World War II history of applied microeconomic research: A generally non-mathematical period; a period of consensus (from the 1960s through the early 1990s) characterized by the use of mathematical models, optimization and equilibrium to generate and...
