We develop a macroeconomic model with physical and human capital, human capital risk, and limited contract enforcement. We show analytically that young (high-return) households are the most exposed to human capital risk and are also the least insured. We document this risk-insurance pattern in...

We use data from the Survey of Consumer Finance and Survey of Income Program Participation to show that young households with children are under-insured against the risk that an adult member of the household dies. We develop a tractable macroeconomic model with human capital risk, age-dependent...

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, component representing measurement error or transitory income shocks and an...

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...

In der vorliegenden Studie werden die Möglichkeiten zur öffentlichen Finanzierung zusätzlicher Klimainvestitionen erörtert. Dabei liegt der Fokus auf zwei Finanzierungsoptionen, die kurzfristig eine Kreditfinanzierung ohne Änderung der verfassungsrechtlich verankerten Schuldenbremse...

This paper considers a class of growth models with idiosyncratic human capital risk and private information about individual effort choices (moral hazard). Households are infinitely-lived and have preferences that allow for a time-additive expected utility representation with a one-period...

Die Dekarbonisierung der deutschen Wirtschaft erfordert bis 2045 einen massiven Aus- und Umbau der Stromnetzinfrastruktur, um unter anderem die Elektrifizierung von Verkehr, Industrie und Gebäuden zu bewältigen. Dies betrifft sowohl die überregionalen Übertragungs-, als auch die regionalen...
