In this paper, I estimate the fiscal impact of immigrants on the German pension insurance (PI) and unemployment insurance (UI) systems when return migration is an endogenous choice. For this purpose, I develop a dynamic stochastic model of joint return migration and saving decisions that...

This paper examines how immigrants' migration duration and saving decisions in the host country respond to the purchasing power parity (ppp) and the wage ratio between the host and source countries. It is shown that in theory immigrants may stay longer in the host country as a result of an...

This paper investigates the determinants of migrants' financial transfers to their home country using German data. A double-hurdle model is applied to analyze the determinants of the propensity to send transfers abroad and the amount of transfers. The findings reveal that return intentions...

This paper analyzes savings and asset holdings of immigrants in relation to their return plans. We argue that savings and asset accumulation may be affected by return plans of immigrants. Further, the way savings and assets are held in the home- and host country may also be related to future...

This paper comprehensively studies the health effects of Daylight Saving Time (DST) regulation. Relying on up to 3.4 million BRFSS respondents from the US and the universe of 160 million hospital admissions from Germany over one decade, we do not find much evidence that population health...

In the Covid-19 crisis, most OECD countries use short-time work schemes (subsidized working time reductions) to preserve employment relationships. This paper studies whether short-time work can save jobs through stabilizing aggregate demand in recessions. We build a New Keynesian model with...

This paper investigates the relationship between wealth, ageing and saving behaviour of private households by using pooled cross sections of German consumption survey data. Different components of wealth are distinguished, as their impact on the savings rate is not homogeneous. On average, the...

How does saving behavior of immigrants respond to changes in purchasing power parity between the source and host countries? We examine this question by building a theoretical model of joint return-migration and saving decisions of temporary migrants and then test its implications by using data...

In May 2001, Germany adopted a fundamental pension reform cutting back public pensions and introducing personal pension accounts. The paper critically reviews the reform decisions and evaluates their long-term viability. It is shown that the adjustment of the Public Pension Scheme misses the...

Western governments are currently contemplating how to adapt their Pay-As-You-Go pension systems so that these remain financially sustainable, even with an aged population. To the extent that policy-makers haven't already adapted their old age social security schemes, an ageing population thus...
