Most countries have automatic rules in their tax-and-transfer systems that are partly intended to stabilize economic fluctuations. This paper measures how effective they are. We put forward a model that merges the standard incomplete-markets model of consumption and inequality with the new...

The 2008 financial crisis is the worst economic crisis since the Great Depression of 1929. It has been characterised by a housing bubble in a context of rapid credit expansion, high risk-taking and exacerbated financial leverage, leading to deleveraging and credit crunch when the bubble burst....

In this Paper, we study the role of subsidies to fertility in ensuring the political viability of unfunded social security (SS). In our model, agents are heterogeneous in age and income. Young generations confront promises made previously by older generations, and in turn choose current levels...

What are the cyclical properties of US state and local government fiscal policy? The budget surplus of local and, in particular, state governments is procyclical, smoothing disposable income and consumption of state residents. This happens over both short- and medium-term horizons. Procyclical...

In thinking about policy, academic economists alternate between theoretical models in which governments can design finely-tuned optimal interventions and practical considerations which usually assume the government to be incompetent and hostage to special interests. I argue in this paper that...

Before the transition governments had strong distributional objectives, which they pursued mainly by direct controls over state enterprise wage rates and hiring decisions, yielding a highly compressed wage distribution. During the reform they maintained similar controls over state enterprises,...

Taxation is only sustainable if the general public complies with it. This observation is uncontroversial with tax practitioners but has been ignored by the public finance tradition, which has interpreted tax constitutions as binding contracts by which the power to tax is irretrievably conferred...

This paper assesses the effects of applying VAT or a sales tax on (intermediate or final) sales of the financial sector. It uses a CGE Model calibrated for a small open economy. It highlights the differentiated sectoral and redistributional effects of these taxes and shows the importance of the...

In this paper we use a simple climate model with endogenous environmental technical change in order to analyse the effects on equity and efficiency of different degrees of restrictions on trade in the market for pollution permits. The model is obtained by incorporating in Nordhaus and Yang...

This Paper considers the optimal design of public pension provision for the retired and income support for those of working age. We consider social security systems that differ in terms of the level of benefits, degree of means testing and the nature of contributions. We aim to find which system...
