We study a fundamental reform of the public Disability Insurance (DI) system in Germany. Effective 2001, cohorts born after 1960 are no longer eligible for "occupational DI." Occupational DI (ODI) implies benefit eligibility when health shocks prevent employees from working in their previous...

This chapter provides an overview of the German long-term care insurance. We document care needs and wellbeing of the elderly population. Moreover, we provide a detailed description of the German long-term care institutions (sources of finance and types of benefits), the professional care work...

This paper studies the effectiveness of forward guidance when central banks have imperfect credibility. Exploiting unique survey-based measures of expected inflation, output growth, and interest rates, we estimate a small-scale New Keynesian model for the United States and other G7 countries...

This paper shows empirically that the non-employment effects of unemployment insurance (UI) for older workers depend in a first-order way on the structure of retirement policies. Using German data, we first present reduced-form evidence of these interactions, documenting large bunching in UI...

We document a housing portfolio channel of quantitative easing (QE) transmission exploiting variation in German household data in a difference-in-differences setting around QE adoption in 2015. We find that QE encourages households with larger initial bond positions to rebalance more toward...

Using transaction-level data from two German banks, we study the effects of smartphones on investor behavior. Comparing trades by the same investor in the same month across different platforms, we find that smartphones increase purchasing of riskier and lottery-type assets and chasing past...

We dissect the impact of a large and sudden exchange rate appreciation on Swiss border import prices, retail prices, and consumer expenditures on domestic and imported non-durable goods, following the removal of the EUR/CHF floor in January 2015. Cross-sectional variation in border price changes...

Job loss comes with large present value earnings losses which elude workhorse models of unemployment and labor market policy. I propose a parsimonious model of a frictional labor market in which jobs differ in terms of unemployment risk and workers search off- and on-the-job. This gives rise to...

Virtually all theories of economic growth predict a positive relationship between population size and productivity. In this paper I study a particular historical episode to provide direct evidence for the empirical relevance of such scale effects. In the aftermath of the Second World War about...
