The means-testing of age pension programs allows governments to control the receipt of pension benefits (extensive margin) and the benefit level (intensive margin). We investigate how the presence of the extensive margin influences the trade-off between protecting the poorer elderly and the...

This paper proposes and assesses consistent multi-factor dynamic ane mortality models for longevity risk applications. The dynamics of the model produce closed-form expressions for survival curves. The framework includes an arbitrage free model specication. Importantly, the mortality model...

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...

There are substantial cross-country differences in labor supply late in the life cycle (age 50+). A theory of labor supply and retirement decisions is developed to quantitatively assess the role of social security, disability insurance, and taxation for understanding differences in labor supply...

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...

The United States is bankrupt, flat broke. Thanks to accounting that would make Enron blush, America’s insolvency goes far beyond what our leaders are disclosing. The United States is a fiscal basket case, in worse shape than the notoriously bailed-out countries of Greece, Ireland, and...

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...
