We propose a canonical model of optimal nonlinear redistributive taxation with matching unemployment. In our model, agents are endowed with different skill levels and labor markets are perfectly segmented by skill. The government only observes negotiated wages. More progressive taxation leads to wage moderation that boosts labor demand. We design the optimal nonlinear redistributive tax schedule in the absence of welfare benefits and extensive labor supply margin. Compared to their efficient values, at the optimum gross wages and unemployment are lower. Average tax rates are moreover increasing in wages. The robustness of these properties is also discussed.

AbstractThe distributive justice literature has recently formulated several tax proposals, with limitarians or property-owning democrats proposing new or higher taxes on wealth or capital income intended to decrease the growing wealth gap. This essay joins this debate on inequality and redistributive taxation through the lens of the "benefit principle for public policy." This principle says that specific rules and institutions are acceptable to the extent that they create benefits for all individuals in society, or at least don't make anyone worse off. This benefit principle opposes wealth accumulation to the extent that wealth was generated through rent-seeking—that is, income unrelated to economic productivity, which is not embedded in mutually beneficial exchanges. I maintain, however, that ruling out rent-seeking requires not ex post taxation, but primarily a more "predistributive corrective policy," that is, reconfiguration of market institutions to prevent wealth accumulation through rent-seeking in the first place. The alternative response is, thus, not to tackle inequality as such but to reform the market to promote the occurrence of mutually beneficial exchange.

The rise in foreign direct investment and the increasing activity of multinational firms expose national corporate tax bases to cross-country profit shifting, but also lead to rising profitability of the corporate sector. We incorporate these two effects of economic integration into a simple political economy model where the median voter decides on a redistributive income tax rate. In this setting economic integration may raise or lower the equilibrium tax rate, depending on whether the higher excess burden of the tax or the larger redistributive gains from the perspective of the representative worker are the dominant effect. Our simple model holds several implications for future empirical work on the relationship between globalization and the effective rate of capital taxation.

This paper characterizes the optimal redistributive tax schedule in a matching unemployment framework where (voluntary) nonparticipation and (involuntary) unemployment are endogenous. The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the global response of the employment rate, which depends not only on the participation (labor supply) responses, but also on the vacancy posting (labor demand) responses and on the product of these two responses. For plausible values of the parameters, our matching environment induces much lower employment tax rates than the usual competitive model with endogenous participation only.
