Can Good Products Drive Out Bad? A Randomized Intervention in the Antimalarial Medicine Market in Uganda

Martina Björkman Nyqvist, Jakob Svensson, 
David Yanagizawa-Drott


How can quality be improved in markets in developing countries, which are known to be plagued by substandard and counterfeit (“fake”, in short) products? We study the market for antimalarial drugs in Uganda, where we randomly assign entry of a retailer (NGO) providing a superior product - an authentic drug priced below the market - and investigate how incumbent firms and consumers respond. We find that the presence of the NGO had economically important effects. Approximately one year after the new market actor entered, the share of incumbent firms selling fake drugs dropped by more than 50% in the intervention villages, with higher quality drugs sold at significantly lower prices.

Can Simple Psychological Interventions Increase Preventive Health Investment?

Anett John
 and Kate Orkin


Behavioral constraints may explain part of low demand for preventive health products. We test the effects of two light-touch psychological interventions on water chlorination and related health and economic outcomes using a randomized controlled trial among 3750 women in rural Kenya. One intervention encourages participants to visualize alternative realizations of the future; one builds participants’ ability to make concrete plans. After 12 weeks, visualization increases objectively measured chlorination, reduces diarrhea episodes among children, and increases savings. Effects on chlorination and savings persist after almost three years.

Climate Change, Inequality, and Human Migration

Michał Burzyński, Christoph Deuster, Frederic Docquier, Jaime de Melo

This paper investigates the long-term implications of climate change on global migration and inequality. Accounting for the effects of changing temperatures, sea levels, and the frequency and intensity of natural disasters, we model the impact of climate change on productivity and utility in a dynamic general equilibrium framework. By endogenizing people’s migration decisions across millions of 5 x 5 km spatial cells, our approach sheds light on the magnitude and dyadic, education- specific structure of human migration induced by global warming.

Organizing Competition for the Market

Elisabetta Iossa, 
Patrick Rey, 
Michael Waterson

We study competition for the market in a setting where incumbents (and, to a lesser extent, neighbouring incumbents) benefit from a cost or information advantage. We first compare the outcome of staggered and synchronous tenders, before drawing the implications for market design. We find the timing of tenders interrelates with the likelihood of monopolisation.

The Adjustment of Labor Markets to Robots

Wolfgang Dauth, Sebastian Findeisen, Jens Suedekum, Nicole Woessner

We use detailed administrative data to study the adjustment of local labor markets to industrial robots in Germany. Robot exposure, as predicted by a shift-share variable, is associated with displacement effects in manufacturing, but those are fully offset by new jobs in services.

The Impact of the First Professional Police Forces on Crime

Anna Bindler, Randi Hjalmarsson

This paper evaluates the effect on crime of creating a fundamental modern-day institution: centralized professional police forces tasked with preventing crime. We study the 1829 formation of the London Metropolitan Police – the first professional force worldwide.
