The paper analyses the interaction between economic incentives and work norms in the context of social insurance. If the work norm is endogenous in the sense that it is weaker when the population share of beneficiaries is higher, then voters will choose less generous benefits than otherwise. We...

This paper discusses how ICT and emerging electronic commerce in consumer products influence the relative efficiency in production of households and firms, resulting in changes in the division of tasks between these two types of agents. Increased information and competence of households, in...

The paper examines the determinants of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organization away from the traditional functional departments and toward multi-tasking and job rotation. Whereas the existing literature on the division...

This paper addresses various attempts by so-called new Keynesians, writing mainly in the 1980s and 1990s, to strengthen the analytical basis, in particular the microeconomic foundations, of these assertions. What, exactly, have then the new Keynesians accomplished, and how should their...

Can income equality be combined with high economic efficiency and rapid economic growth? Fortunately, we need not to answer such a general question. Indeed, the question is poorly phrased. The relationship between income and wealth distribution, on one hand, and efficiency/growth, on the other,...

This paper applies a systems-oriented, “holistic” approach to China’s radical economic reforms during the last quarter of a century. It characterizes China’s economic reforms in terms of a multidimensional classification of economic systems. When looking at the economic consequences of...

The publication of János Kornai’s memoirs, By Force of Thought, provides an excellent opportunity to remind ourselves of Kornai’s great contributions to economic research. This paper discusses both his basic research strategy and some of his main research results. Kornai has usually dealt...

In this paper we treat an individual’s health as a continuous variable, in contrast to the traditional literature on income insurance, where it is regularly treated as a binary variable. This is not a minor technical matter; in fact, a continuous treatment of an individual’s health sheds new...

The expansion of welfare-state arrangements is seen as the result of dynamic interaction between market behaviour and political behaviour, often with considerable time lags, sometimes generating either virtuous or vicious circles. Such interaction may also involve induced (endogenous) changes in...

We characterize pension systems along three dimensions: 1) actuarial vs. non-actuarial, 2) funded vs. pay-as-you-go, 3) defined-contribution vs. defined-benefit. Increasing the degree of actuarial fairness, by strengthening the linkage between contributions and benefits, reduces labor market...
