War, Inflation, and Social Capital
利用俄罗斯79个地区的周度数据，通过互联网搜索强度衡量亲社会行为，发现通货膨胀冲击降低社会资本，而乌克兰冲突强度则提升社会资本。
We use weekly data from 79 Russian regions to measure the impact of economic shocks and proximity to war in Ukraine on social capital in Russian regions. We proxy social capital by the relative intensity of internet searches for the most salient dimensions of pro-social behavior such as “donate blood”, “charity”, “adopt a child” etc. This measure of social capital is correlated with a survey-based measure of generalized social trust. Our search-based measure of social capital responds negatively to the spikes of inflation and positively to the intensity of the conflict in Ukraine (controlling for region and week fixed effects).
