We solve a model with incomplete markets and heterogeneous agents that generates a large equity premium, while simultaneously matching stock market participation and individual asset holdings. The high risk premium is driven by incomplete risk sharing among stockholders, which results from the...

We use a general equilibrium life-cycle model with incomplete markets and heterogeneous agents to evaluate the macroeconomic and welfare implications of Defined Benefit (DB) versus Defined Contribution (DC) systems, and to investigate the effects of incremental reform within a particular system....

Motivated by the success of internal habit formation preferences in explaining asset-pricing puzzles, we introduce these preferences in a life-cycle model of consumption and portfolio choice with liquidity constraints, undiversifiable labour income risk and stock-market participation costs. In...

We solve and estimate a life-cycle model with earnings risk and liquidity constraints in the presence of tax-deferred retirement accounts (TDAs). We explicitly consider two very different types of households (with TDAs): direct and indirect stockholders. The latter hold stocks only through TDAs...

Motivated by the success of internal habit formation preferences in explaining asset pricing puzzles, we introduce these preferences in a life-cycle model of consumption and portfolio choice with liquidity constraints, undiversifiable labor income risk and stock-market participation costs. In...

Financing retirement benefits is probably the most significant fiscal challenge that governments in industrial economies will be facing in the next few decades. Social security reform has therefore become an important public policy issue for many countries and various reform proposals have been...

We develop a model with incomplete markets and heterogeneous agents that generates a large equity premium, while simultaneously matching stock market participation and individual asset holdings. The high risk-premium is driven by incomplete risk sharing among stockholders, which results from the...

We utilize an overlapping generations model with endogenous production and incomplete markets to quantify the distortionary costs associated with financing the increase in government expenditures directed to investments in the private sector in 2008 and 2009 (also known as ‘the bailout’),...
