Can Gambling Increase Savings? Empirical Evidence on Prize-Linked Savings Accounts
By: Shawn A. Cole, Benjamin Iverson and Peter Tufano
This paper studies the adoption and impact of prize-linked savings (PLS) accounts, which offer lottery-like payouts to individual account holders in lieu of interest. Using microlevel data from a bank in South Africa, we show that PLS is attractive to a broad group of...

Which Markets (Don't) Drive Pharmaceutical Innovation? Evidence From U.S. Medicaid Expansions
By: Craig Garthwaite, Rebecca Sachs and Ariel Dora Stern
Pharmaceutical innovation policy involves managing a tradeoff between high prices for new products in the short-term and stronger incentives to develop products for the future. Prior research has documented a causal relationship between market size and pharmaceutical...

Do Police Reduce Crime? Estimates Using the Allocation of Police Forces after a Terrorist Attack
By: Rafael Di Tella and Ernesto Schargrodsky
An important challenge in the crime literature is to isolate causal effects of police on crime. Following a terrorist attack on the main Jewish center in Buenos Aires, Argentina, in July 1994, all Jewish institutions received police protection. Thus, this hideous event...

Learning Down to Train Up: Mentors Are More Effective When They Value Insights from Below
By: Ting Zhang, Dan Wang and Adam D. Galinsky
Although mentorship is vital for individual success, potential mentors often view it as a costly burden. To understand what motivates mentors to overcome this barrier and more fully engage with their mentees, we introduce a new construct, learning direction, which...

Designs for Estimating the Treatment Effect in Networks with Interference
By: Ravi Jagadeesan, Natesh S. Pillai and Alexander Volfovsky
In this paper, we introduce new, easily implementable designs for drawing causal inference from randomized experiments on networks with interference. Inspired by the idea of matching in observational studies, we introduce the notion of considering a treatment...

Leaders: Stop Confusing Correlation with Causation
By: Michael Luca
We’ve all been told that correlation does not imply causation. Yet many business leaders, elected officials, and media outlets still make causal claims based on misleading correlations. These claims are too often unscrutinized, amplified, and mistakenly used to guide...

Handgun Waiting Periods Reduce Gun Deaths
By: Michael Luca, Deepak Malhotra and Christopher Poliquin
Handgun waiting periods are laws that impose a delay between the initiation of a purchase and final acquisition of a firearm. We show that waiting periods, which create a “cooling off” period among buyers, significantly reduce the incidence of gun violence. We estimate...

How Much Should We Trust Staggered Difference-In-Differences Estimates?
By: Andrew C. Baker, David F. Larcker and Charles C.Y. Wang
We explain when and how staggered difference-in-differences regression estimators, commonly applied to assess the impact of policy changes, are biased. These biases are likely to be relevant for a large portion of research settings in finance, accounting, and law that...

Poverty and Crime: Evidence from Rainfall and Trade Shocks in India

Does poverty lead to crime? We shed light on this question using two independent and exogenous shocks to household income in rural India: the dramatic reduction in import tariffs in the early 1990s and rainfall variations. We find that trade shocks, previously shown to...

Buying Time Promotes Happiness
By: A.V. Whillans, Elizabeth W. Dunn, Paul Smeets, Rene Bekkers and Michael I. Norton
Around the world, increases in wealth have produced an unintended consequence: a rising sense of time scarcity. We provide evidence that using money to buy time can provide a buffer against this time famine, thereby promoting happiness. Using large, diverse samples...

When Democracy Breaks: Studies in Democratic Erosion and Collapse, from Ancient Athens to the Present Day
By: Archon Fung, David Moss and Odd Arne Westad
Democracy is often described in two opposite ways, as either wonderfully resilient or dangerously fragile. Curiously, both characterizations can be correct, depending on the context. When Democracy Breaks aims to deepen our understanding of what separates democratic...
