Assessing bankruptcy reform in a model with temptation and equilibrium default
A life-cycle model with equilibrium default in which consumers with and without temptation coexist is constructed to evaluate the 2005 bankruptcy law reform and other counterfactual reforms. The calibrated model indicates that the 2005 bankruptcy reform achieves its goal of reducing the number of bankruptcy filings, as seen in the data, but at the cost of loss in social welfare. The creditor-friendly reform provides borrowers with a stronger commitment to repay and thus yields lower default premia and better consumption smoothing. However, those who borrow and default due to temptation or ...

Optimal capital income taxation with housing
This paper quantitatively investigates the optimal capital income taxation in the general equilibrium overlapping generations model, which incorporates characteristics of housing and the U.S. preferential tax treatment for owner-occupied housing. Housing tax policy is found to have a substantial effect on how capital income should be taxed. Given the U.S. preferential tax treatment for owner-occupied housing, the optimal capital income tax rate is close to zero, contrary to the high optimal capital income tax rate implied by models without housing. A lower capital income tax rate implies a ...

Understanding house-price dynamics
For most homeowners, housing is the single most important component of their nonpension wealth. Therefore, a change in house prices greatly affects the total wealth of many households. Furthermore, movements in house prices can affect people?s lives indirectly. For example, the surge in the number of mortgage defaults and foreclosures during the recent recession was triggered in part by a drop in house prices, and this surge damaged the health of the financial institutions that either directly or indirectly owned mortgage loans. In turn, the deteriorating health of the financial sector was ...

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 ...

Reverse mortgage loans: a quantitative analysis
Supersedes Working Paper 13-27. Reverse mortgage loans (RMLs) allow older homeowners to borrow against housing wealth without moving. Despite growth in this market, only 2.1% of eligible homeowners had RMLs in 2011. In this paper, the authors analyze reverse mortgages in a calibrated life-cycle model of retirement. The average welfare gain from RMLs is $885 per homeowner. The authors? model implies that low-income, low-wealth, and poor-health households benefit the most, consistent with empirical evidence. Bequest motives, nursing-home-move risk, house price risk, and loan costs all ...

Doves for the Rich, Hawks for the Poor? Distributional Consequences of Monetary Policy
We build a New Keynesian business-cycle model with rich household heterogeneity. A central feature is that matching frictions render labor-market risk countercyclical and endogenous to monetary policy. Our main result is that a majority of households prefer substantial stabilization of unemployment even if this means deviations from price stability. A monetary policy focused on unemployment stabilization helps Main Street" by providing consumption insurance. It hurts Wall Street" by reducing precautionary saving and, thus, asset prices. On the aggregate level, household heterogeneity ...

Credit, bankruptcy, and aggregate fluctuations
We ask two questions related to how access to credit affects the nature of business cycles. First, does the standard theory of unsecured credit account for the high volatility and procyclicality of credit and the high volatility and countercyclicality of bankruptcy filings found in U.S. data? Yes, it does, but only if we explicitly model recessions as displaying countercyclical earnings risk (i.e., rather than having all households fare slightly worse than normal during recessions, we ensure that more households than normal fare very poorly). Second, does access to credit smooth aggregate ...

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 ...

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.

Worker flows and job flows: a quantitative investigation
This paper studies quantitative properties of a multiple-worker firm search/matching model and investigates how worker transition rates and job flow rates are interrelated. We show that allowing for job-to-job transitions in the model is essential to simultaneously account for the cyclical features of worker transition rates and job flow rates. Important to this result are the distinctions between the job creation rate and the hiring rate and between the job destruction rate and the layoff rate. In the model without job-to-job transitions, these distinctions essentially disappear, thus making ...
