지방선거와 선거 당일 날씨 효과: 사전투표제 도입 이후를 중심으로 [Election Day Weather Effects in Local Elections in the Period with the Early Votin

This paper analyzes the election day weather effects in South Korean local elections. Analyzing the election day precipitation and temperature data estimated at the town level, along with the results of the 7th and 8th provincial council proportional representation elections, we found that for every 1sd (3.1mm) increase in election day precipitation, the vote share of progressive parties increases by 1.8%, while that of conservative parties decreases by about 2.7%. Unlike in national assembly elections, despite the introduction of the early voting system, election day weather still influences election results. Furthermore, compared to the precipitation effects observed in national assembly election results before the introduction of the early voting system, the effect of election day weather in local elections appears to be larger.
