Reforming the US Long-Term Care Insurance Market
Nursing home risk is significant and costly. Yet, most Americans pay for long-term care (LTC) expenses out-of-pocket. This chapter examines reforms to both public and private LTCI provision using a structural model of the US LTCI market. Three policies are considered: universal public LTCI, no public LTCI coverage, and a policy that exempts asset holdings from the public insurance asset test on a dollar-for-dollar basis with private LTCI coverage. We find that this third reform enhances social welfare and creates a vibrant private LTCI market while preserving the safety net provided by public ...

Saving and interest rates in Japan: why they have fallen and why they will remain low
This paper quantifies the role of alternative shocks in accounting for the recent declines in Japanese saving rates and interest rates and provides some projections about their future course. We consider three distinct sources of variation in saving rates and real interest rates: changes in fertility rates, changes in survival rates, and changes in technology. The empirical relevance of these factors is explored using a computable dynamic OLG model. We find that the combined effects of demographics and slower total factor productivity growth successfully explain both the levels and the ...

Old, sick, alone, and poor: a welfare analysis of old-age social insurance programs
Poor health, large acute and long-term care medical expenses, and spousal death are significant drivers of impoverishment among retirees. We document these facts and build a rich, overlapping generations model that reproduces them. We use the model to assess the incentive and welfare effects of Social Security and means-tested social insurance programs such as Medicaid and food stamp programs, for the aged. We find that U.S. means-tested social insurance programs for retirees provide significant welfare benefits for all newborn. Moreover, when means-tested social insurance benefits are of the ...

Seasonal Solow residuals and Christmas: a case for labor hoarding and increasing returns
In aggregate unadjusted data, measured Solow residuals exhibit large seasonal variations. Total Factor Productivity grows rapidly in the fourth quarter at an annual rate of 16 percent and regresses sharply in the first quarter at an annual rate of ?24 percent. This paper considers two potential explanations for the measured seasonal variation in the Solow residual: labor hoarding and increasing returns to scale. Using a specification that allows for no exogenous seasonal variation in technology and a single seasonal demand shift in the fourth quarter, we ask the following question: How much ...

Uninsured risk, stagnation, and fiscal policy
Japan is in the midst of a protracted spell of depressed economic activity. Japan's economic stagnation has occurred against a background of rising earnings risk. Occupational stability is falling as routine occupations disappear and implicit lifetime employment guarantees are gradually disappearing. At the same time, earnings in some high-skilled occupations have continued to grow. The resulting polarization in earnings has also been accompanied by an increase in wealth inequality. We develop a framework that relates these observations. In our model, an increase in uninsured earnings risk ...

The role of damage-contingent contracts in allocating the risks of natural catastrophes
The distinguishing feature of natural-catastrophe risk is claimed to be aggregate risk. Because such risk is encompassed in the general competitive model, it seems to pose no new theoretical challenge. However, that model has markets contingent on exogenous events, while the actual economy seems to be developing mainly markets contingent on the level of total damage. In the context of a model with aggregate risk and endogenous total damage, a notion of competitive markets contingent on total damage is formulated. That notion implies that such markets achieve the same (efficient) risk sharing ...

Aging, Deflation, and Secular Stagnation
Prior to the COVID pandemic, industrialized countries experienced a sustained episode of low inflation, low real interest rates, and low per capita gross domestic product (GDP) growth. As the logistical and other disruptions created by the COVID pandemic fade, will industrialized economies once again face downward pressure on prices, real interest rates, and output growth? We present evidence that the aging of the population was depressing the inflation rate, as well as real interest rates and GDP growth, prior to the COVID pandemic. Aging is ongoing in industrialized countries, and it will ...

Transaction services, inflation, and welfare
This paper is motivated by empirical observations on the comovements of currency velocity, inflation, and the relative size of the credit services sector. We document these comovements and incorporate into a monetary growth model a credit services sector that provides services that help people economize on money. Our model makes two new contributions. First, we show that direct evidence on the appropriately defined credit service sector for the United States is consistent with the welfare cost measured using an estimated money demand schedule. Second, we provide welfare cost of inflation ...

Making the case for a low intertemporal elasticity of substitution
We provide two ways to reconcile small values of the intertemporal elasticity of substitution (IES) that range between 0.35 and 0.5 with empirical evidence that the IES is large. We do this reconciliation using a model in which all agents have identical preferences and the same access to asset markets. We also conduct an encompassing test, which indicates that specifications of the model with small values of the IES are more plausible than specifications with a large IES.
