Slovakia’s fundamental tax reform of 2004 considerably improved the simplicity and efficiency of the tax system by eliminating exemptions and special regimes and setting the rates for the personal income tax (PIT), the corporate income tax (CIT) and the value added tax (VAT) all equal to 19%....

Mexico has a relatively large informal sector by OECD standards. While this is in part a symptom of limited development and low productivity, it can also be to some extent its cause, as informal firms stay small to hide their activities and have limited access to productivity-enhancing...

Social insurance for the elderly is judged responsible for the widely observed trend towards early retirement. In a world of laissez-faire or in a first-best setting, there would be no such trend. However, when first-best instruments are not available, because health and productivity are not...

During the period from 1880 to 1950 publicly managed retirement security programs became an important part of the social fabric in most advanced economies. In this paper we study the social, demographic and economic origins of social security. We describe a model economy in which demographics,...

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the Diamond (1965) OLG model, we find that intergenerational transfers arise in the absence of...

In many countries pension systems involve some form of earnings test; i.e., an individual’s benefits are reduced if he has labour income. This paper examines whether or not such earning tests emerge when pension system and income tax are optimally designed. We use a simple model with...

This paper studies the determination through majority voting of a pension scheme when society consists of far-sighted and myopic individuals. All individuals have the same basic preferences but myopics tend to adopt a short term view (instant gratification) when dealing with retirement saving....

In this Paper, we study the role of subsidies to fertility in ensuring the political viability of unfunded social security (SS). In our model, agents are heterogeneous in age and income. Young generations confront promises made previously by older generations, and in turn choose current levels...

This paper studies the design of retirement and disability policies. It illustrates the often observed exit from the labour force of healthy workers through disability insurance schemes. Two types of individuals, disabled and leisure-prone ones, have the same disutility for labour and cannot be...

Brazil’s public pension expenditure is about 9 per cent of GDP, above the OECD average. Given that OECD countries are generally not only wealthier, but also significantly older, Brazil’s pension expenditures are clearly excessive, draining resources away from other areas, such as much needed...
