Amazon Mechanical Turk is a very widely-used tool in business and economics research, but how trustworthy are results from well-published studies that use it? Analyzing the universe of hypotheses tested on the platform and published in leading journals between 2010 and 2020 we find evidence of...

Randomized controlled trials (RCTs) are increasingly prominent in economics, with pre-registration and pre-analysis plans (PAPs) promoted as important in ensuring the credibility of findings. We investigate whether these tools reduce the extent of p-hacking and publication bias by collecting and...

The economics 'credibility revolution' has promoted the identification of causal relationships using difference-in-differences (DID), instrumental variables (IV), randomized control trials (RCT) and regression discontinuity design (RDD) methods. The extent to which a reader should trust claims...

In this paper, we examine the relationship between p-hacking and data-sharing policies for published articles. We collect 38,876 test statistics from 1,106 articles published in leading economic journals between 2002 2020. While a data-sharing policy increases the provision of research data to...

In response to COVID-19, dramatic safer-at-home policies were implemented. The understanding of their impacts on social distancing, travel and pollution is in its infancy. We pair a differences-in-differences framework and synthetic control methods with rich cellular tracking and high frequency...

This paper examines the impact of terrorism on voting behavior in the United States. We rely on an exhaustive list of terror attacks over the period 1970-2016 and exploit the inherent randomness of the success or failure of terror attacks to identify the political impacts of terrorism. We first...

In New York City (NYC), it has been a common complaint that it is difficult to find a taxi in the rain. Using all Uber rides in NYC from April to September 2014 and January to June 2015, we show that the number of Uber rides is significantly correlated with whether it rained. The number of Uber...

This paper analyzes the determinants behind the spatial distribution of the LGBT population in the U.S. We relate the size of the present-day LGBT population to the discovery of gold mines during the 19th century gold rushes. Comparing the surroundings of these gold mines to other current and...

In this paper, we investigate the effect of a change in childcare subsidies on parental subjective well-being. Starting in 1997, the Canadian province of Québec implemented a generous program providing $5-a-day childcare to children under the age of 5. By 2007, the percentage of children...
