We study how marital property laws shape household saving and investment decisions, exploiting regional variation in statutory defaults across Spain. Using this variation as an instrument, we find that Separate Property reduces household saving but has no significant average effect on stock market participation. This null effect, however, masks sharply opposing responses: Separate Property increases participation by 8.9 percentage points when the wife is the financial head (the spouse most knowledgeable about household finances) and decreases it by 10.7 percentage points when the husband is, independently of spouses’ relative earnings. To explain these findings, we develop a dynamic collective life-cycle model with limited commitment, endogenous divorce, and portfolio choice. The model highlights two distinct channels: financial management shapes how property regimes affect stock market participation costs, while spouses’ ownership claims upon divorce influence saving and marital stability through endogenous asset titling. In a counterfactual that extends Separate Property to the rest of Spain, the model predicts lower divorce rates and a redistribution of welfare from husbands to wives. Our findings show that marital property laws shape household financial behavior not only through ownership rights, but also through the organization of financial decision-making within marriage.

This paper studies the impact of inheritance taxation on intragenerational wealth mobility. To do so, I exploit rich variation in tax rates across Spanish regions resulting from the decentralization of this tax to regional governments. Using household panel data from the Spanish Survey of Household Finances, I document that higher inheritance taxes significantly and persistently reduce heirs’ wealth mobility at the lower part of the net wealth distribution. These wealth mobility responses to higher taxes are explained by less wealthy heirs decreasing their financial wealth and increasing their personal credit debt. Liquidity constraints and some particularities of the tax enforcement help rationalize the rise in personal credit debt at the time of the tax payment. Illiquidity of inheritances helps explain the lasting negative effects of taxes on bottom-wealth mobility, as delays in selling inherited real estate amplify the negative effects of taxes on personal credit debt and financial wealth of less wealthy heirs.
