Is Charitable Giving Political? New Evidence from Wealth and Income Tax Returns

What are the determinants of philanthropic and political giving? Are donations to charities and parties driven by the same incentives? In this article, we use new administrative household panel data to quantify empirically the motivations for giving, depending on donors' characteristics and tax incentives. Our dataset includes all the households filling their income tax and/or their wealth tax returns in France between 2006 and 2019. In France, both charitable and political donations benefit from income tax deductions, but only the charitable ones are eligible to the wealth tax credit. We exploit the 2018 wealth tax reform a change in the taxable base that led to a drop by two third in the number of liable households to estimate the cross-price elasticity of charitable and political giving at different levels of the income and wealth distributions. We provide new evidence of substituability between charitable and political donations: according to our estimates, a one-percent increase in the price of charitable giving leads to a 19 to 25 increase in political donations. The magnitude of this effect is particularly strong among the the top 20 of the wealth taxpayers.
