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...

We provide a model for analyzing effects of the tax system and spending programs on the determination of government spending and taxpayer welfare and show that tax system or spending program which is suboptimal from a Ramsey point of view can improve taxpayer welfare because the system creates...

This paper demonstrates that there is a robust empirical association between the extent to which an economy is exposed to trade and the size of its government sector. This association holds for a large cross-section of countries, in low- as well as high-income samples, and is robust to the...

One possible explanation for the difficulty in controlling the budget is that a major component of spending --tax expenditures--receives privileged status. It is treated as tax cuts rather than spending. This paper explores the implications of that classification and illustrates how it can lead...

This paper investigates the causal effect of job training on wage rates in the presence of firm heterogeneity. When training affects worker sorting to firms, sample selection is no longer binary but is "multilayered". This paper extends the canonical Heckman (1979) sample selection model - which...

We use a data set of federal corruption convictions in the U.S. to investigate the causes and consequences of corruption. More educated states, and to a less degree richer states, have less corruption. This relationship holds even when we use historical factors like education in 1928 or...

This paper shows that smaller countries have larger public sectors as a share of GDP, and are also more open to trade. These empirical observations are consistent with recent theoretical models explaining country formation and break up
