{"title":"Introduction to the symposium on reproducibility and replicability in economics: Part II","authors":"Farasat A. S. Bokhari, Abel Brodeur, Michalis Drouvelis","doi":"10.1111/ecin.70026","DOIUrl":"https://doi.org/10.1111/ecin.70026","url":null,"abstract":"<p>The second part of the symposium on reproducibility and replicability in economics is a direct continuation of the first part, featuring further reproductions and replications of influential studies in the economics literature. This emphasis aims to rigorously scrutinize established findings within the economic literature and ultimately highlights the progress and the systemic challenges that persist in reproduction and replication efforts. The second part of the symposium includes 11 studies which span a diverse array of economic inquiries—including immigration and innovation, cultural evolution, trade and language, opioid policy, investor sentiment, public goods cooperation, technological inequality, criminal justice policy, commodity price forecasting, and historical climate-economy relationship—and at the same time, demonstrates how replication deepens our understanding of both micro- and macro-level phenomena while reinforcing the empirical foundations of economics as a self-correcting science. We provide a short summary of each article below.</p><p>The first article, “Replication of ‘How Much Does Immigration Boost Innovation?’,” examines the impact of skilled immigration on innovation in the United States, measured by patenting activity. A concern in this line of work is the endogenous location choice of skilled immigrants, which is typically addressed using shift–share instruments Recent research has raised questions about the validity of such instruments—specifically, that the identifying variation comes from historical shares rather than from shifts in inflows—and has developed diagnostic tools to identify which groups drive the identification. Using reconstructed data and modern shift–share instrumental variable techniques, the author confirms that skilled immigrants significantly boost innovation. However, the analysis also shows that the identifying variation in the instrument is concentrated among a few origin countries, raising potential concerns about exogeneity. Despite this nuance, the positive relationship between skilled immigration and innovation remains robust across multiple econometric specifications.</p><p>In the second article, “Understanding Cultural Persistence and Change: A Replication of Giuliano and Nunn (2021),” the authors revisit the link between ancestral climatic variability and individual-level cultural traits. The reproduction carefully examines the alignment between the paper's stated methods and its implementation, identifying several discrepancies in how samples were constructed and variables coded. After applying corrections to better reflect the original methodological descriptions, many of the main effects become weaker or statistically insignificant.</p><p>The article titled “Trade and Ethnolinguistic Differences: A Replication and Extension” revisits the hypothesis that historical inter-ethnic trade opportunities influence linguistic similarities between neighboring ethnolinguistic groups.
