Gridlock: Ethnic Diversity in Government and the Provision of Public Goods
利用加州城市议会选举数据，发现议会种族多样性增加会减少公共品支出，尤其在高度隔离和经济不平等城市，且连任得票率下降，表明内部分歧导致支出降低。
How does ethnic diversity in government impact public good provision? We construct a novel dataset linking the ethnicity of California city council candidates to election outcomes and expenditure decisions. Using a regression discontinuity approach, we find that increased diversity on the council leads to less spending on public goods. This is especially true in cities with high segregation and economic inequality. Those serving on councils that experience an increase in diversity also receive fewer votes when they run for reelection. These results point towards disagreement within the council generating lower spending.
