Income Mobility and Welfare
This paper develops a framework for the quantitative analysis of individual income dynamics, mobility and welfare. Individual income is assumed to follow a stochastic process with two (unobserved) components, an i.i.d. component representing measurement error or transitory income shocks and an AR(1) component representing persistent changes in income. We use a tractable consumption-saving model with labor income risk and incomplete markets to relate income dynamics to consumption and welfare, and derive analytical expressions for income mobility and welfare as a function of the various parameters of the underlying income process. The empirical application of our framework using data on indiv...
Macroeconomic Evaluation of Labor Market Reform in Germany
In 2005 the German government implemented the so-called Hartz IV reform, which amounted to a complete overhaul of the German unemployment insurance system and resulted in a significant reduction in unemployment benefits for the long-term unemployed. In this paper, we use an incomplete-market model with search unemployment to evaluate the macro-economic and welfare effects of the Hartz IV reform. We calibrate the model economy to German data before the reform and then use the calibrated model economy to simulate the effects of Hartz IV. In our baseline calibration, we find that the reform has reduced the long-run (noncyclical) unemployment rate in Germany by 1.4 percentage points. We also find that the welfare of employed households increases, but the welfare of unemployed households decreases even with moderate degree of risk aversion.
Labor Market Institutions and the Cost of Recessions
This paper studies the effect of two labor market institutions, unemployment insurance (UI) and job search assistance (JSA), on the output cost and welfare cost of recessions. The paper develops a tractable incomplete-market model with search unemployment, skill depreciation during unemployment, and idiosyncratic as well as aggregate labor market risk. The theoretical analysis shows that an increase in JSA and a reduction in UI reduce the output cost of recessions by making the labor market more fluid along the job finding margin and thus making the economy more resilient to macroeconomic shocks. In contarst, the effect of JSA and UI on the welfare cost of recessions is in general ambiguous. The paper also provides a quantitative appliation to the German labor market reforms of 2003-2005, the so-called Hartz reforms, which improved JSA (Hartz III reform) and reduced UI (Hartz IV reform). According to the baseline calibration, the two labor market reforms led to a substantial reduction in the output cost of recessions and a moderate reduction in the welfare cost of recessions in Germany.
The Economics of Growth
A comprehensive, rigorous, and up-to-date introduction to growth economics that presents all the major growth paradigms and shows how they can be used to analyze the growth process and growth policy design. This comprehensive introduction to economic growth presents the main facts and puzzles about growth, proposes simple methods and models needed to explain these facts, acquaints the reader with the most recent theoretical and empirical developments, and provides tools with which to analyze policy design. The treatment of growth theory is fully accessible to students with a background no more advanced than elementary calculus and probability theory; the reader need not master all the subtle...
Trade Policy, Income Risk and Welfare
"This paper studies empirically the relationship between trade policy and individual income risk faced by workers, and uses the estimates of this empirical analysis to evaluate the welfare effect of trade reform. The analysis proceeds in three steps. First, longitudinal data on workers are used to estimate time-varying individual income risk parameters in various manufacturing sectors. Second, the estimated income risk parameters and data on trade barriers are used to analyze the relationship between trade policy and income risk. Finally, a simple dynamic incomplete-market model is used to assess the corresponding welfare costs. In the implementation of this methodology using Mexican data, we find that trade policy changes have a significant short run effect on income risk. Further, while the tariff level has an insignificant mean effect, it nevertheless changes the degree to which macroeconomic shocks affect income risk"--NBER website
The Great Reset
This timely and insightful collection of essays written by economists from a range of academic and policy institutes explores the subject of public investment through two avenues. The first examines public investment trends and needs in Europe, addressing the initiatives taken by European governments to tackle the COVID-19 recession and to rebuild their economies. The second identifies key domains where European public investment is needed to build a more sustainable Europe, from climate change to human capital formation. Building on the 2020 edition, The Great Reset demonstrates the value of public capital both within European countries and as a European public good, shedding light on the i...
