We analyse the impact of micro-founded political institutions on environmental policy and economic growth. We model an overlapping-generations economy, where individuals differ in preferences over the environment (as well as in age). Labour taxation and capital taxation is used to finance a...

A 'folk theorem' originating, among others, in the work of Stiglitz maintains that competitive equilibria are always or 'generically' inefficient (unless contracts directly specify consumption levels as in Prescott and Townsend, thus bypassing trading in anonymous markets). This paper critically...

Local network externalities are present when the utility of buying from a firm not only depends on the number of other customers (global network externalities), but also on their identity and/or characteristics. We explore the consequences of local network externalities within a framework where...

We investigate the effects of fiscal policy surprises for US data, using vector autoregressions. We overcome the difficulties that changes in fiscal policy may manifest themselves in variables other than fiscal variables first and that fiscal variables may respond ‘automatically’ to business...

In a seminal contribution, Romer and Romer (2010) introduce a new dataset of exogenous tax changes and estimate a tax multiplier at 3 years of about -3. These results have been criticized as implausibly large. In this paper, I argue that on theoretical grounds the discretionary component of...

After the Global Financial Crisis a controversial rush to fiscal austerity followed in many countries. Yet research on the effects of austerity on macroeconomic aggregates was and still is unsettled, mired by the difficulty of identifying multipliers from observational data. This paper...

How much additional tax revenue can the government generate by increasing labor income taxes? In this paper we provide a quantitative answer to this question, and study the importance of the progressivity of the tax schedule for the ability of the government to generate tax revenues. We develop...

Cross-country evidence on inflation and inequality suggests that they are positively correlated. I explore the hypothesis that this correlation is the outcome of a distributional conflict underlying the determination of fiscal policy.

Long-run trends in Africa’s well-being are provided on the basis of a new index of human development, alternative to the UNDP’s HDI. A sustained improvement in African human development is found that falls, nonetheless, short of those experienced in other developing regions. Within Africa,...
