This paper discusses different empirical tests of public sector solvency and applies them to a sample of 18 OCED countries. Provided that the government solvency constraint need to be imposed, these tests develop from the idea of verifying whether the intertemporal budget constraint of the...

This paper analyses the effects of fiscal policies on rates of interest and wealth in the world economy. Uncertainty concerning the length of life yields an equilibrium in which private and social rates of discount differ and budget deficits exert real effects. It is shown that a current budget...

This paper analyzes optimal spending, tax and financial policies in models of endogenous growth where public spending is productive. We extend previous work in four directions. First, we analyze optimal policies when the government is allowed to borrow and lend, rather than being restricted to...

This paper develops and estimates a dynamic optimizing model of the current account. The model focuses, on real factors that determine the evolution of saving and investment, and hence the external balance. Three types of shocks are at the center of the analysis: productivity shocks, shocks to...

In this paper, we try to interpret several important trends in the size of governments and government deficits in the OECD economies : the rapid increase in the public spending to GDP ratio in the 1970s; the sharp rise in budget deficits and in debt-GNP ratios after 1973; and the early signs of a...

The propagation of macroeconomic shocks through input-output and geographic networks can be a powerful driver of macroeconomic fluctuations. We first exposit that in the presence of Cobb-Douglas production functions and consumer preferences, there is a specific pattern of economic transmission...

The paper analyzes the effect of the generosity of the welfare state on the skill composition of immigrants. We develop a parsimonious model in which the effect of an increase in the generosity (and taxes) of the welfare state on the skill composition of immigrants under free migration is...

Several recent theories emphasize the negative effects of an aging population on economic growth, either because of the lower labor force participation and productivity of older workers or because aging will create an excess of savings over desired investment, leading to secular stagnation. We...

This paper tests the differential effects of the generosity of the welfare state under free migration and under policy-controlled migration, distinguishing between source developing and developed countries. We utilize free-movement within the EU to examine the free migration regime and compare...
