It is argued that a PAYGO system may have useful allocative functions in that it serves as an insurance against not having children and as an enforcement device for 'rotten kids' who are unwilling to pay their parents a pension. It is true that the system has a moral hazard effect in terms of...

This paper argues that increased factor mobility incurs the risk of dismantling the welfare state, even though this state may have useful allocative functions. It will be difficult to finance the welfare state with taxes on capital and it may even be necessary to subsidize this factor in the...

We build a two-sector dynamic general equilibrium model with one-sided substitutability between fossil carbon and biocarbon. One shock only, the discovery of the technology to use fossil fuels, leads to a transition from an initial pre-industrial phase to three following phases: a pure fossil...

This note generalizes the Solow-Stiglitz efficiency condition for natural resources to the problem of fossil fuel extraction with a greenhouse effect. The generalized optimality condition suggests that the greenhouse effect implies overextraction in the sense of leaving future generations a...

Richard Musgrave was one of the around 200 academic economists who emigrated from Germany when Fascism came to dominate the country. This memorial lecture traces the German and European roots of Richard Musgrave's oeuvre, trying to shed light on his family background as well as on the political...

The emergence of the Asian tiger countries and the participation of the ex-communist countries in world trade has reduced the equilibrium price of labor in western Europe and elsewhere. However, the actual price of labor hardly reacts, because the welfare state's minimum replacement incomes are...

It is not surprising that the U.S. has been by far the world's largest shock producer in this crisis. The big shock absorbers on the other hand were Japan, Russia and Germany, whose exports shrank more than their imports

A political miracle occurred when Germany was reunited, and at first glance an economic miracle has followed. Real incomes in the east have now reached the western level, and investment per capita has been much higher than in the west. However, every third deutschmark spent in the east has been...

This paper studies alternative methods of privatizing a formerly communist firm in the presence of imperfect risk markets. The methods include cash sales, a give-away scheme, and a participation contract where the government retains a sleeping fractional ownership in the firm. It is shown that,...

The paper argues that Lucas overestimates the Friedman-Bailey type of welfare cost of inflation and neglects other important welfare effects. With an alternative interpretation of the non-observability of low interest rates than the one Lucas gave and the introduction of taxes that reduce the...
