We investigate whether estimates of the effect of aid on growth are influenced by authors' careers. We collect data on the careers of 190 authors and apply meta-regression analysis to investigate the impact of authors' age and tenure status on the reported magnitude of aid effectiveness, and on...

Over the past several decades, meta-analysis has emerged as a widely accepted tool to understand economics research. Meta-analyses often challenge the established conventional wisdom of their respective fields. We systematically review a wide range of influential meta-analyses in economics and...

This paper provides concise, nontechnical, step-by-step guidelines on how to conduct a modern meta-analysis, especially in social sciences. We treat publication bias, p-hacking, and heterogeneity as phenomena meta-analysts must always confront. To this end, we provide concrete methodological...

We demonstrate that all meta-analyses of partial correlations are biased, and yet hundreds of meta-analyses of partial correlation coefficients (PCC) are conducted each year widely across economics, business, education, psychology, and medical research. To address these biases, we offer a new...

Conventional meta-analyses of correlations are biased due to the correlation between the estimated correlation and its standard error, Simulations that are closely calibrated to match actual research conditions widely seen across correlational studies in psychology corroborate these biases and...

In this paper we investigate whether the effects of terrorism in one country spillover to affect trade in neighboring nations. Using a sample of more than 160 countries from 1976 to 2014, we report robust evidence that terrorist attacks in a nation's contiguous neighbors significantly reduce...
