Topic: Measuring Changes in Corruption Over Time
Abstract: Although the most commonly used quantitative measures of corruption are highly correlated, we find that these measures do not accurately track changes in corruption within a given country over time. Many causal inference research designs, such as difference-in-difference designs and dynamic panel instrumental variable models, rely on such within-country changes to identify causal relationships. As a result, we argue that findings based on changes in corruption within countries should be interpreted with caution. We show that factor scores extracting the common signal from multiple measures should be preferred to any single measure of corruption when studying changes within a country over time.
