Working Paper
Consumer Bankruptcy, Mortgage Default and Labor Supply
Li, Wenli; Meghir, Costas; Oswald, Florian (2022-08-30)
We specify and estimate a lifecycle model of consumption, housing demand and labor supply in an environment where individuals may file for bankruptcy or default on their mortgage. Uncertainty in the model is driven by house price shocks, education specific productivity shocks, and catastrophic consumption events, while bankruptcy is governed by the basic institutional framework in the U.S. as implied by Chapter 7 and Chapter 13. The model is estimated using micro data on credit reports and mortgages combined with data from the American Community Survey. We use the model to understand the ...

Closing Small and "Sufficiently" Large Open Economies with Different Asset Structures
Restrepo-Echavarria, Paulina (2024-12-06)
There are two important dimensions that matter when we write down a model economy of a country that is open to international financial markets. The first one is its size, and the second one is its asset market structure. Small open economies are price takers so the analysis happens in partial equilibrium, while countries that are “sufficiently" large can affect international prices and the analysis happens in general equilibrium. The second important dimension is the asset market structure. If markets are complete there is full risk sharing, while if markets are incomplete there is not. In ...

A Comment on 'Wealth Inequality and Endogenous Growth' by Byoungchan Lee
Gu, Shijun; Jia, Chengcheng (2022-10-17)
How does wealth inequality affect economic growth? Byoungchan Lee answers this question by developing a heterogeneous-agent model and augmenting it with endogenous firm innovation. The novel channel is that rising wealth concentration reduces aggregate demand, which gives firms a disincentive to spend on R&D and therefore leads to slower productivity growth. In this discussion, we first explain the difference in calibration strategy between Lee’s approach and the common approach in the literature, and then discuss its quantitative implications for the effect of rising inequality on ...

Income Differences and Health Disparities: Roles of Preventive vs. Curative Medicine
Ozkan, Serdar (2024-08-28)
Using data from the Medical Expenditure Panel Survey (MEPS) I find that early in life the rich spend significantly more on health care, whereas from middle to very old age the poor outspend the rich by 25% in the US. Furthermore, while low-income individuals are less likely to incur medical expenses, they are more prone to experiencing extreme expenses when they do seek care. To account for these facts, I develop and estimate a life-cycle model of two types of health capital: physical and preventive. Physical health capital determines survival probabilities, whereas preventive health capital ...

Optimal Time-Consistent Taxation with Default
Karantounias, Anastasios G. (2017-11-01)
We study optimal time-consistent distortionary taxation when the repayment of government debt is not enforceable. The government taxes labor income or issues noncontingent debt in order to finance an exogenous stream of stochastic government expenditures. The government can repudiate its debt subject to some default costs, thereby introducing some state-contingency to debt. We are motivated by the fact that domestic sovereign default is an empirically relevant phenomenon, as Reinhart and Rogoff (2011) demonstrated. Optimal policy is characterized by two opposing incentives: an incentive to ...

Idiosyncratic Investment Risk and Business Cycles
Goldberg, Jonathan (2014-01-10)
I show that, due to imperfect risk sharing, aggregate shocks to uncertainty about idiosyncratic return on investment generate economic contractions with elevated risk premia and a decrease in the risk-free rate. I present a tractable real business cycle model in which firms experience idiosyncratic shocks, to which managers are at least partially exposed; the distribution of these shocks is time-varying and stochastic. I show that the path for aggregate quantities, the price of physical capital, and the equity premium are the same as in a model without idiosyncratic risk, but with ...

The Piketty Transition
Carroll, Daniel R.; Young, Eric R. (2014-12-03)
We study the effects on inequality of a "Piketty transition" to zero growth. In a model with a worker-capitalist dichotomy, we show first that the relationship between inequality (measured as a ratio of incomes for the two types) and growth is complicated; zero growth can raise or lower inequality, depending on parameters. Extending our model to include idiosyncratic wage risk we show that growth has quantitatively negligible effects on inequality, and the effect is negative. Finally, following Piketty?s thought experiment, we study how the transition might occur without declining returns; ...

How Important Is Health Inequality for Lifetime Earnings Inequality?
Hosseini, Roozbeh; Kopecky, Karen A.; Zhao, Kai (2021-01-04)
Using a dynamic panel approach, we provide empirical evidence that negative health shocks reduce earnings. The effect is primarily driven by the participation margin and is concentrated in less educated individuals and those with poor health. We build a dynamic, general equilibrium, life cycle model that is consistent with these findings. In the model, individuals whose health is risky and heterogeneous choose to either work, or not work and apply for social security disability insurance (SSDI). Health affects individuals’ productivity, SSDI access, disutility from work, mortality, and ...

Discrete Choice, Complete Markets, and Equilibrium
Mongey, Simon; Waugh, Michael E. (2024-02-07)
This paper characterizes the allocations that emerge in general equilibrium economies populated by households with preferences of the additive random utility type that make discrete consumption, employment or spatial decisions. We start with a complete markets economy where households can trade claims contingent upon the realizations of their preference shocks. We (i) establish a first and second welfare theorem, (ii) illustrate that in the absence of ex-ante trade, discrete choice economies are generically inefficient, (iii) show that complete markets are not necessary and a much smaller set ...
