Vertical Fiscal Externalities and Federal Tax-Transfers under Variable Factor Supplies

Within a model of variable supply of capital due to international mobility and variable labor supply due to endogenous labor-leisure choice, we revisit the issues of vertical fiscal externalities, and of federal tax-transfers. Capital and labor taxes by federal and state governments finance the provision of federal and of state public consumption goods. When capital and labor are substitutes in production, we show that (i) the state’s optimal policy calls for capital and labor taxes, (ii) the vertical fiscal externality can be reversed from negative, implying inefficiently high noncooperative capital taxes, to positive, implying inefficiently low noncooperative capital taxes, and (iii) under centralized leadership the federal government replicates the second best optimum with a capital tax, and possibly, top-down transfers.

GENERAL EQUILIBRIUM FEEDBACK REGARDING THE EMPLOYMENT EFFECTS OF LABOR TAXES

A higher labor tax rate increases the equilibrium real interest rate and reduces the equilibrium wage in a heterogeneous-agent model with endogenous savings and indivisible labor supply decisions. I show that these general equilibrium (GE) adjustments, in particular of the real interest rate, reinforce the negative employment impact of higher labor taxes. However, the representative-agent version of the model, which generates similar aggregate employment responses to labor tax changes, implies that GE feedback is neutral. The cross-country panel data reveal that the negative association between labor tax rates and the extensive margin labor supply is significantly and robustly weaker in small open economies where the interest rate is less tightly linked to domestic circumstances. This empirical evidence supports the transmission mechanism of labor tax changes for employment in the heterogeneous-agent model.

The Taxing Deed of Globalization

This paper examines the effects of globalization on the distribution of worker-specific labor taxes using a unique set of tax calculators. We find a differential effect of higher trade and factor mobility on relative tax burdens in 1980–1993 versus 1994–2007 in the OECD. Prior to 1994, greater openness meant that higher income earners were taxed progressively more. However, after 1994, we document a globalization-induced rise in the labor income tax burden of the middle class, while the top 1 percent of workers and employees faced a reduction in their tax burden of 0.59–1.45 percentage points.

ON THE EFFECTIVENESS OF FISCAL DEVALUATIONS IN A MONETARY UNION

This paper examines the effects of fiscal devaluations in a model of a monetary union characterized by national fiscal policies and supranational monetary policy. We show that a revenue-neutral permanent tax shift in one country, which raises its consumption tax to finance a cut to labor taxes, increases welfare of the monetary union in the long run. The distribution of gains among countries depends on their degree of financial integration. We also document that price rigidities result in short-run welfare costs.

CAPITAL TAXES, LABOR TAXES AND THE HOUSEHOLD

We study the impact of capital and labor taxation in an economy where couples bargain over the intrahousehold allocation under limited commitment. In this framework more wealth improves commitment and gives rise to insurance gains within the household. Our theory motivates these gains by the empirical observation that wealth, in contrast to labor income, is a commonly held resource within households. Based on this observation we study whether eliminating capital taxes from the economy, and raising labor taxes to balance the government’s budget, may generate welfare gains to married households. We illustrate that the quantitative effects from this reform are rather small. We attribute the small effects to the life cycle pattern of wealth accumulation and to the impact of labor income taxes on household risk sharing: In particular, we show that higher labor taxes may make the limited commitment friction more severe, even though they may make the distribution of labor income more equitable within the household.
