In this paper we study the social, demographic and economic origins of social security. The data for the U.S. and for a cross section of countries make it clear that urbanization and industrialization are strongly associated with the rise of social insurance. We describe a model economy in which...

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...

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...

The present paper reviews key issues in pension design and pension reform encountered all across the world. The paper heavily refers to the recent U.S. Social Security reform debate in general and to the Personal Retirement Accounts proposal in particular. A particular emphasis is put on...

We examine the interactions between public and private sector wages per employee in OECD countries. The growth of public sector wages and of public sector employment positively affects the growth of private sector wages. Moreover, total factor productivity, the unemployment rate and the degree...

This paper estimates the size of the informal economy for 32 mainly Latin American and Caribbean countries in the early 2000s. Using a structural equation modeling approach, we find that a stringent tax system and regulatory environment, higher inflation, and dominance of the agriculture sector...

The paper develops a general equilibrium framework to examine the economic implications of population aging in Japan. Particular attention is paid to aggregate saving behavior which is modeled on the basis of empirical age-earnings profiles using a life-cycle approach. The paper's objectives are...

This paper uses an overlapping generations model with international labor mobility and a politically responsive fiscal policy to examine aging in developed and developing regions. Migrant workers change the political structure composed of young and elderly voters in both labor-receiving and...

Sweden represents an archetypal welfare state economy, with extensive government safety nets. Some scholars have attributed a decline in its per capita income ranking since 1970 to "eurosclerosis" or sluggish growth caused by distortionary policies. This paper argues rather, that the permanent...

We use the IMF's Global Fiscal Model to evaluate recent proposals to reform social security and the tax system in the United States. Introducing personal retirement accounts is unlikely to yield significant macroeconomic benefits unless it spurs additional fiscal consolidation to prevent a large...
