How much does political uncertainty matter? The case of Louisiana under Huey Long

We study the effect of political uncertainty on economic outcomes using the case of Huey Long's tenure as governor and senator of Louisiana during the Great Depression. Based on primary sources, we construct two well-established measures of uncertainty specifically for Louisiana: stock price volatility and newspaper mentions of terms related to “uncertainty” and the economy. Combining these uncertainty measures with employment data from the Census of Manufactures, we attempt to identify the effects of political uncertainty using the state of Mississippi as a control group. We find little support for a negative effect from political uncertainty in Huey Long's Louisiana.
