When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations. We derive the equilibrium dynamics in closed form and show that joint presence of both...

We ask whether a pay-as-you-go financed social security system is welfare improving in an economy with idiosyncratic productivity and aggregate business cycle risk. We show analytically that the whole welfare benefit from joint insurance against both risks is greater than the sum of benefits...

This paper studies the effects of public infrastructure investment policies. A dynamic general equilibrium model where the effective stock of public infrastructure is an input in production is used to analyze the consequences of changing the share of GDP devoted to public investment....

Motivated by the highly-unionized public sectors, the high public shares in total em- ployment, and the public sector wage premia observed in Europe, this paper examines the importance of public sector unions for macroeconomic theory. The model gen- erates cyclical behavior in hours and wages...

We quantify marginal excess burden, defined as the change in deadweight loss for an additional dollar of tax revenue, for different taxes. We use a dynamic general equilibrium, overlapping generations model featured with heterogeneous agents and a realistic structure of corporate finance and...

This paper aims to assess tax policy reforms that can sustain universal basic income programs and foster long-term growth and welfare in a currency union that faces fiscal rule constraints and inequality. To address this ongoing government and economics' debate, we developed a Dynamic Stochastic...

The accession negotiations of Belarus to the WTO are unusual since, due to its obligations in the Eurasian Economic Union, WTO accession is not expected to impact its tariffs or formerly substantial trade distorting agricultural subsidies. Nonetheless, we estimate that WTO accession will...

This paper characterizes the out-of-equilibrium dynamics of a symmetric, pure exchange economy with two goods and N agents with uniformly distributed preferences and identical endowments. Relaxing the auctioneer assumption, but maintaining a global price rule, sequentially random pairwise...
