In their 1996 article in the British Journal of Politic Science, Robert Jackman and Karin Volpert examine the conditions favoring parties of the extreme right in western Europe. They report strong evidence that unemployment, electoral thresholds and multi-partism affect the electoral success of extreme right parties. As a result, they conclude that support for the extreme right is sensitive to factors that can be modified through policy instruments. Although the article makes important contributions by emphasizing the role of electoral institutions and the methodological problems associated with selection bias, a reanalysis shows that a number of their inferences are open to question. I successfully replicate their original analysis, critique their interpretation of the causal effects, and question their model’s theoretical justification.
