Almost unknown in 1960, the value added tax (VAT) is now found in more than 130 countries, raises around 20 percent of the world’s tax revenue, and has been the centerpiece of tax reform in many developing countries. This paper explores the causes and consequences of the remarkable rise of the...

Increasing marginal tax rates and making payments to the poor reduce inequality and introduce savings dis-incentives. Using a heterogeneous agent model with incomplete markets, we show that higher taxes (and transfers) decrease consumption inequality but also mean savings and mean consumption....

This paper provides an analysis relating economic growth, human capital composition, income distribution and public education policies.

This article explains how changing many structural parameters by discrete amounts affect many variables of interest when we have no explicit expressions for the variables of interest in terms of the structural parameters. Although the matrix multiplying a vector of discrete changes in parameters...

We estimate the multiplier by relying on differences in spending in infrastructure across Italian provinces and an instrument identifying investment changes that are large and exogenous to local cyclical conditions. We derive our instrument from the an Italia law mandating the interruption of...

We study the dynamic Ramsey problem of finding optimal public debt and linear taxes on capital and labor income within a tractable infinite horizon model with incomplete markets. With zero public expenditure and debt, it is optimal to tax the risky labor income and subsidize capital, while a...

We consider an economy where individuals face uninsurable risks to their human capital accumulation, and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

While politically attractive in order to generate tax revenues, the effects of a financial transaction tax (FTT) are scientifically disputed, not the least because seemingly small details of its implementation may matter a lot. In this paper, we provide experimental evidence on the different...

This paper investigates the relationship between fiscal consolidation, business plans and firm investment. Based on a detailed narrative of tax changes in Germany covering 40 years of fiscal adjustments, we define and exploit the exogenous variation of tax bills to quantify the effect of tax...

The global financial crisis of 2008–09 has sent public debt on sharply higher trajectories. With the economic recovery gradually taking hold, the focus is now shifting to fiscal “exit” strategies. Medium-term consolidation efforts are likely to include not only tax increases but also...
