Accounting for Cross-Country Differences in Intergenerational Earnings Persistence: The Impact of Taxation and Public Education Expenditure

I document a strong negative cross-country correlation between intergenerational earnings persistence and tax progressivity, and between intergenerational earnings persistence and public expenditure on tertiary education. To explain these correlations I then develop an intergenerational life-cycle model of human capital accumulation and earnings, which features, progressive taxation, public education expenditure, and borrowing constraints among the determinants of earnings persistence. I calibrate the model to US data and use it to decompose the contributions to earnings persistence from different model elements and to quantify how earnings persistence in the US changes as I introduce tax- and eduction expenditure policies from other countries. I find that individual investments in human capital accounts for 62% of the estimated intergenerational earnings persistence in the US. Taxation, through its impact on investments in human capital, can explain 25% of the difference between the US and 10 other countries, whereas borrowing constraints have a limited impact on earnings persistence.

Fiscal Multipliers in the 21st century

The recent experience of a Great Recession has brought the effectiveness of fiscal policy back into focus. Fiscal multipliers do, however, vary greatly over time and place. Running VARs for a large number of countries, we document a strong correlation between wealth inequality and the magnitude of fiscal multipliers. To explain this finding, we develop a life-cycle, overlapping generations economy with uninsurable labor market risk. We calibrate our model to match key characteristics of a number of OECD economies, including the distribution of wages and wealth, social security, taxes and debt and study the effects of changing policies and various forms of inequality on the fiscal multiplier. We find that the fiscal multiplier is highly sensitive to the fraction of the population who face binding credit constraints and also negatively related to the average wealth level in the economy. This explains the correlation between wealth inequality and fiscal multipliers.

How Does Tax Progressivity and Household Heterogeneity Affect Laffer Curves

How much additional tax revenue can the government generate by increasing labor income taxes? In this paper we provide a quantitative answer to this question, and study the importance of the progressivity of the tax schedule for the ability of the government to generate tax revenues. We develop a rich overlapping generations model featuring an explicit family structure, extensive and intensive margins of labor supply, endogenous accumulation of labor market experience as well as standard intertemporal consumption-savings choices in the presence of uninsurable idiosyncratic labor productivity risk. We calibrate the model to US macro, micro and tax data and characterize the labor income tax Laffer curve under the current choice of the progressivity of the labor income tax code as well as when varying progressivity. We find that more progressive labor income taxes significantly reduce tax revenues. For the US, converting to a flat tax code raises the peak of the Laffer curve by 6%, whereas converting to a tax system with progressivity similar to Denmark would lower the peak by 7%. We also show that, relative to a representative agent economy tax revenues are less sensitive to the progressivity of the tax code in our economy. This finding is due to the fact that labor supply of two earner households is less elastic (along the intensive margin) and the endogenous accumulation of labor market experience makes labor supply of females less elastic (around the extensive margin) to changes in tax progressivity.

Fiscal Consolidation Programs and Income Inequality

Following the Great Recession, many European countries implemented fiscal consolidation policies aimed at reducing government debt. Using three independent data sources and three different empirical approaches, we document a strong positive relationship between higher income inequality and stronger recessive impacts of fiscal consolidation programs across time and place. To explain this finding, we develop a life-cycle, overlapping generations economy with uninsurable labor market risk. We calibrate our model to match key characteristics of a number of European economies, including the distribution of wages and wealth, social security, taxes and debt, and study the effects of fiscal consolidation programs. We find that higher income risk induces precautionary savings behavior, which decreases the proportion of credit-constrained agents in the economy. Credit-constrained agents have less elastic labor supply responses to fiscal consolidation achieved through either tax hikes or public spending cuts, and this explains the relationship between income inequality and the impact of fiscal consolidation programs. Our model produces a cross-country correlation between inequality and the fiscal consolidation multipliers, which is quite similar to that in the data.

The Real Effects of Financial (Dis)Integration: A Spatial Equilibrium Analysis of Europe

Using data from 15 European Union economies, we quantify the real effects of supply-side frictions due to the financial disintegration of European countries since the 2008 financial crisis. We develop a multi-country general equilibrium model with heterogeneous countries and destination-specific financial frictions. Financial institutions allocate capital endogenously across countries, determining the cost of capital to firms and the wealth of nations. The cost of financial disintegration is reduced access to capital for firms which results in lower output. Financial disintegration leads to a 0.54% fall in output in Europe since the crisis. We also estimate benefits of further financial integration.
