This paper employs an Overlapping Generations Model to quantify the impacts of Korea's demographic transition toward an older population on the total output growth rate. The model incorporates the projected population through 2060 according by Statistics Korea. The effects of the low fertility...

We quantify the effects of population aging on the U.S. healthcare system. Our analysis is based on a stochastic general equilibrium overlapping generations model of endogenous health accumulation calibrated to match pre-2010 U.S. data. We find that population aging not only leads to large...

This paper utilizes a life-cycle overlapping-generations model to quantify the welfare effects of plans to postpone the depletion of the National Pension Fund. In order for the model to incorporate the rapidly changing demographic structure of Korea fully, we build and calibrate a model in...

Many countries consider rising fertility through pro-family policies as a solution to the fiscal pressure stemming from longevity. However, an increased number of births implies immediate private costs and only delayed public benefits of younger and larger population. We propose using an...

The theoretical literature presumes generational risk is large enough to merit study and that such risk can be meaningfully shared via appropriate government policies. This paper assesses these propositions. It develops a computational technique to overcome the curse of dimensionality and...

We explicitly solve for the aggregate asset prices in a discrete-time general-equilibrium endowment economy with two agents who differ with respect to their preferences for risk aversion and sensitivity to habit, either internal or external. We compute equilibrium quantities -- equity premium,...

In this study, we quantify the macroeconomic and welfare effects of alternative fiscal consolidation plans in the context of a small open economy. Using a computable overlapping generations model tailored to the Australian economy, we examine immediate and gradual eliminations of the existing...

The paper presents a computationally efficient method to solve overlapping generations models with asset choice. The method is used to study an OLG economy with many cohorts, up to 3 different assets, stochastic volatility, short-sale constraints, and subject to rather large technology shocks.On...

Previous writers have attempted to resolve the equity premium puzzle by employing a utility function that depends on current consumption minus (or relative to) past habit consumption. This paper points out that an individual's current utility may also depend upon how well off in the recent past...

We construct a dynamic stochastic general equilibrium model with overlapping generations in order to analyze the optimality of means-testing pension benefits in the UK. While previous studies only consider the long-run welfare effects of alternative policy reforms, we compute the full transition...
