This article reviews and summarizes current reproduction and replication practices in political science. We first provide definitions for reproducibility and replicability. We then review data availability policies for 28 leading political science journals and present the results from a survey...

We propose a framework for evaluating reproducibility and replicability in economics. Reproducibility is defined as testing if the results of an original study can be reproduced using the same data and replicability is defined as testing if the results of an original study hold in new data. We...

A typical empirical study involves choosing a sample, a research design, and an analysis path. Variation in such choices across studies leads to heterogeneity in results that introduce an additional layer of uncertainty not accounted for in reported standard errors and confi dence intervals. We...

This study pushes our understanding of research reliability by reproducing and replicating claims from 110 papers in leading economic and political science journals. The analysis involves computational reproducibility checks and robustness assessments. It reveals several patterns. First, we...

In this paper, we use a sample of almost 30,000 Swedish mono- and dizygotic twins to study the heritability of financial risk-taking. Following a major pension reform in the year 2000, virtually all Swedish adults had to simultaneously make a financial decision affecting post-retirement wealth....

A striking fact about entrepreneurship is that the number of male entrepreneurs greatly exceed the number of female entrepreneurs. We use detailed survey data from Sweden to study to what extent this gender gap can be explained by gender differences in personality. We show that women have...

We test whether generosity is related to political preferences and partisanship in Canada, Sweden, the United Kingdom and the United States using incentivized dictator games. The total sample consists of more than 5,000 respondents. We document that support for social spending and redistribution...

Twins-based estimates of the return to schooling feature prominently in the labor economics literature. The validity of such estimates hinges critically on the assumption that within-pair variation in schooling is explained by factors which are unrelated to wage earning ability. This paper...

Guilt averse individuals experience a utility loss if they believe they let someone down. In particular, generosity depends on what the donor believes that the recipient expects to receive. In experimental work, several authors have identified a positive correlation between such second-order...
