Survival of the Fittest: The Impact of the Minimum Wage on Firm Exit

Survival of the Fittest: The Impact of the Minimum Wage on Firm Exit. Michael Luca, April 11, 2017, Paper, “We study the impact of the minimum wage on firm exit in the restaurant industry, exploiting recent changes in the minimum wage at the city level. The evidence suggests that higher minimum wages increase overall exit rates for restaurants. However, lower quality restaurants, which are already closer to the margin of exit, are disproportionately impacted by increases to the minimum wage. Our point estimates suggest that a one dollar increase in the minimum wage leads to a 14 percent increase in the likelihood of exit for a 3.5-star restaurant (which is the median rating), but has no discernible impact for a 5-star restaurant (on a 1 to 5 star scale).Link

Fixing Discrimination in Online Marketplaces

Fixing Discrimination in Online Marketplaces. Michael Luca, December 2016, Paper, “In the late 1980s, law professors Ian Ayres and Peter Siegelman set out to learn whether blacks and women got the same deals as white men when buying a new car. They trained 38 people—some white and some black, some male and some female—to negotiate a purchase using a fixed script, and uncovered disturbing differences: Across 153 dealerships, black and female buyers paid more for the same cars than white men did, with black women paying the most—on average, nearly $900 more than white men. Although the findings weren’t a surprise to most people, least of all to blacks and women, they were a compelling demonstration of just how discriminatory markets can be.Link

Productivity and Selection of Human Capital with Machine Learning

Productivity and Selection of Human Capital with Machine Learning. Michael Luca, Sendhil Mullainathan, 2016, Paper. “Economists have become increasingly interested in studying the nature of production functions in social policy applications, Y = f(L, K), with the goal of improving productivity. For example what is the effect on student learning from hiring an additional teacher, ∂Y/∂L, in theory (Lazear, 2001) or in practice (Krueger, 2003)? What is the effect of hiring one more police officer (Levitt, 1997)?Link

Racial Discrimination in the Sharing Economy: Evidence from a Field Experiment

Racial Discrimination in the Sharing Economy: Evidence from a Field Experiment. Benjamin Edelman, Michael Luca, December 9, 2015, “Online marketplaces increasingly choose to reduce the anonymity of buyers and sellers in order to facilitate trust. We demonstrate that this common market design choice results in an important unintended consequence: racial discrimination. In a field experiment on Airbnb, we find that requests from guests with distinctively African-American names are roughly 16% less likely to be accepted than identical guests with distinctively White names. The difference persists…Link

The Behavioural Economics of Voluntary Disclosure

The Behavioural Economics of Voluntary Disclosure. Michael Luca, July 22, 2015, Paper. “Theories of voluntary disclosure suggest that even when disclosure is voluntary, market forces can drive firms to completely reveal information about their quality. This column investigates these predictions in an experimental setting. Laboratory results suggest widespread failures of the theoretical predictions – senders do not fully disclose, and receivers are not fully sceptical about non-disclosure. This suggests a role for policymakers to help customers understand the sound of silence…Link
