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 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...

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...

I discuss the role of economic theory in empirical work in development economics with special emphasis on general equilibrium and political economy considerations. I argue that economic theory plays (should play) a central role in formulating models, estimates of which can be used for...

In this paper, I develop a model to analyze how skill premia differ over time and across countries, and use this model to study the impact of international trade on wage inequality. Skill premia are determined by technology and the relative supply of skills. An increase in the relative supply of...
