We develop a dynamic stochastic general equilibrium model to study bank risk and sovereign risk interdependence in the Euro Area. We find that an increase in capital investment risk shock, results in a considerably deeper recession when sovereign risk is also present. This result has three...

Can public insurance through redistributive income taxation improve the allocation of risk in an economy in which private risk sharing is limited? The answer depends crucially on the fundamental friction that limits private risk sharing in the first place. If risk sharing is incomplete because...

This paper studies an overlapping generations model with stochastic production and incomplete markets to assess whether the introduction of an unfunded social security system leads to a Pareto improvement. When returns to capital and wages are imperfectly correlated a system that endows retired...

Between 2007 and 2009, government expenditures increased rapidly across the OECD countries. While economic research on the impact of government purchases has flourished, in the data, about three quarters of the increase in expenditures in the United States (and more in other countries) was in...

Our aim is to provide insights into some basic facts of US government debt management by introducing simple financial frictions in a Ramsey model of fiscal policy. We find that the share of short bonds in total U.S. debt is large, persistent, and highly correlated with total debt. A well known...

This paper develops an analytical framework to study consumption and labour supply in a rich class of heterogeneous-agent economies with partial insurance. The environment allows for trade in non-contingent and state-contingent bonds, for permanent and transitory idiosyncratic productivity...

When is it optimal for a government to default on its legal repayment obligations? We answer this question for a small open economy with domestic production risk in which the government optimally fi…nances itself by issuing non-contingent debt. We show that Ramsey optimal policies occasionally...

An incomplete markets life-cycle model with indivisible labour makes career lengths and human capital accumulation respond to labour tax rates and government supplied non-employment benefits. We compare aggregate and individual outcomes in this individualistic incomplete markets model with those...

This paper offers a theory of development which links the degree of market incompleteness to capital accumulation and growth. At early stages of development, the presence of indivisible projects limits the degree of risk-spreading (diversification) that the economy can achieve. The desire to...

Financial markets are incomplete, thus for many households borrowing is possible only by accepting a financial contract that specifies a fixed repayment. However, the future income that will repay this debt is uncertain, so risk can be inefficiently distributed. This paper argues that a monetary...
