The present paper constructs possible baseline economies with an aging population to analyze Social Security reform plans, using an overlapping generations (OLG) model with heterogeneous households. In this model, households receive idiosyncratic working ability shocks and mortality shocks....

This paper provides general equilibrium estimates of the steady-state welfare gains of lowering inflation from a low level to close to price stability, using an overlapping-generations growth model. Money demand is modeled on the basis that real money balances are a factor of production....

We propose a framework for understanding recurrent historical episodes of vigorous economic expansion accompanied by extreme asset valuations, as exhibited by the U.S. in the 1990s. We interpret this phenomenon as a high-valuation equilibrium with a low effective cost of capital based on...

In the standard neoclassical model with a representative agent, a benevolent planner who can commit to future policies will, if feasible, levy a single confiscatory tax on capital in the initial period and commit never to set positive taxes thereafter. We show that this policy, which allows for...

In the debate over federal budget deficits, several politicians have proposed to change the formulas that determine benefit levels for Social Security and other government programs as well as income tax brackets. Switching to a relatively new formula, the Chained CPI, would help the federal...

At moderate levels, debt improves welfare and enhances growth. But high levels can be damaging. When does debt go from good to bad? We address this question using a new dataset that includes the level of government, non-financial corporate and household debt in 18 OECD countries from 1980 to...

This paper sheds new light on the growth implications of public debt introducing a dynamic panel threshold model by accounting for regime dependent intercepts and focusing on 12 Euro zone economies over the 1980-2012 period. The threshold estimates for debt are estimated by using multiple...

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...
