We conducted a randomized controlled trial involving nearly 700 customer-service representatives (CSRs) in a Canadian government service agency to study whether providing CSRs with performance feedback with or without peer comparison affected their subsequent organ donor registration rates....

A political miracle occurred when Germany was reunited, and at first glance an economic miracle has followed. Real incomes in the east have now reached the western level, and investment per capita has been much higher than in the west. However, every third deutschmark spent in the east has been...

We use a detailed micro dataset on product availability to construct a direct high-frequency measure of consumer product shortages during the 2020-2021 pandemic. We document a widespread multi-fold rise in shortages in nearly all sectors early in the pandemic. Over time, the composition of...

We evaluate the impact of government mandated proof of vaccination requirements for access to public venues and non-essential businesses on COVID-19 vaccine uptake. We find that the announcement of a mandate is associated with a rapid and significant surge in new vaccinations (more than 60\%...

It has often been asserted that imposition of environmental regulations in the 1970's may be a partial explanation for the productivity growth slowdowns experienced by most industrialized countries during that decade.The contention is that expenses incurred to satisfy these regulations, such as...

This paper assesses the quantitative effects of a shift to monetary restraint in the United States on the DM-$ exchange rate and the German economy. The results indicate that such effects are large. If Germany keeps its money growth unchanged, it will tend to experience a sharp and sustained...

Many households hold little wealth, especially liquid wealth. In precautionary savings models, absent preference heterogeneity, these households should display not only higher marginal propensities to consume (MPCs), but also lower average propensities to consume (APCs) and higher future...

This paper provides evidence on child penalties in female and male earnings in different countries. The estimates are based on event studies around the birth of the first child, using the specification proposed by Kleven et al. (2018). The analysis reveals some striking similarities in the...

We estimate the effects of a mandate allocating a third of corporate board seats to workers (shared governance). We study a reform in Germany that abruptly abolished this mandate for certain firms incorporated after August 1994 but locked it in for the older cohorts. In sharp contrast to the...

This note lays out the basic Susceptible-Infected-Recovered (SIR) epidemiological model of contagion, with a target audience of economists who want a framework for understanding the effects of social distancing and containment policies on the evolution of contagion and interactions with the...
