Business cycles in the equilibrium model of labor market search and self-insurance
The author introduces risk-averse preferences, labor-leisure choice, capital, individual productivity shocks, and market incompleteness to the standard Mortensen-Pissarides model of search and matching and explore the model's cyclical properties. There are four main findings. First and foremost, the baseline model can generate the observed large volatility of unemployment and vacancies with a realistic replacement ratio of the unemployment insurance benefits of 64 percent. Second, labor-leisure choice plays a crucial role in generating the large volatilities; additional utility from leisure ...

The redistributive consequences of monetary policy
Monetary policy is not intended to benefit one segment of the population at the expense of another by redistributing income and wealth. But as Makoto Nakajima explains, it is probably impossible to avoid such redistributive consequences.

Monetary Policy with Racial Inequality
I develop a heterogeneous-agent New-Keynesian model featuring racial inequality in income and wealth, and studies interactions between racial inequality and monetary policy. Black and Hispanic workers gain more from accommodative monetary policy than White workers mainly due to higher labor market risks. Their gains are larger also because of a larger proportion of them are hand-to-mouth, while wealthy White workers gain more from asset price appreciation. Monetary and fiscal policies are substitutes in providing insurance against cyclical labor market risks. Racial minorities gain even more ...

Taxing The 1 Percent
Raising taxes on top earners is often seen as a straightforward way to stem inequality. The trick is preserving efficient revenue generation and work incentives for the economy?s most productive contributors.

Reverse mortgage loans: a quantitative analysis
Reverse mortgage loans (RMLs) allow older homeowners to borrow against housing wealth without moving. In spite of growth in this market, only 2.1% of eligible homeowners had RMLs in 2011. In this paper, we analyze reverse mortgages in a life-cycle model of retirement, calibrated to age-asset profiles. The ex-ante welfare gain from RMLs is sizable at $1,000 per household; ex-post, low-income, low-wealth and poor-health households use them. Bequest motives, nursing-home moving risk, house price risk, and interest and insurance costs all contribute to the low take-up rate. The model predicts ...

Capital Income Taxation with Housing
This paper quantitatively investigates capital income taxation in the general-equilibrium overlap-ping generations model with household heterogeneity and housing. Housing tax policy is found to affect how capital income should be taxed, due to substitution between housing and non-housing capital. Given the existing U.S. preferential tax treatment for owner-occupied housing, the optimal capital income tax rate is close to zero (1%), contrary to the high optimal capital income tax rate found with overlapping generations models without housing. A low capital income tax rate improves welfare by ...

Health-care reform or labor market reform? A quantitative analysis of the affordable care act
An equilibrium model with firm and worker heterogeneity is constructed to analyze labor market and welfare implications of the Patient Protection and Affordable Care Act, commonly called the Affordable Care Act (ACA). The authors? model implies a significant reduction in the uninsured rate from 22.6 percent to 5.6 percent. The model predicts a moderate positive welfare gain from the ACA because of the redistribution of income through health insurance subsidies at the exchange as well as the Medicaid expansion. About 2.1 million more part-time jobs are created under the ACA at the expense of ...

A quantitative theory of unsecured consumer credit with risk of default
The authors study, theoretically and quantitatively, the general equilibrium of an economy in which households smooth consumption by means of both a riskless asset and unsecured loans with the option to default. The default option resembles a bankruptcy filing under Chapter 7 of the U.S. Bankruptcy Code. Competitive financial intermediaries offer a menu of loan sizes and interest rates wherein each loan makes zero profits. They prove the existence of a steady-state equilibrium and characterize the circumstances under which a household defaults on its loans. They show that their model accounts ...

A quantitative analysis of unemployment benefit extensions
This paper measures the effect of extensions of unemployment insurance (UI) benefits on the unemployment rate using a calibrated structural model that features job search and consumption-saving decision, skill depreciation, UI eligibility, and UI benefit extensions that capture what has happened during the current downturn. The author finds that the extensions of UI benefits contributed to an increase in the unemployment rate by 1.2 percentage points, which is about a quarter of an observed increase during the current downturn (a 5.1 percentage point increase from 4.8 percent at the end of ...
