Pro-Cyclical Unemployment Benefits? Optimal Policy in an Equilibrium Business Cycle Model

We study the optimal provision of unemployment insurance (UI) over the business cycle. We consider an equilibrium Mortensen-Pissarides search and matching model with risk-averse workers and aggregate shocks to labor productivity. Both the vacancy creation decisions of firms and the search effort decisions of workers respond endogenously to aggregate shocks as well as to changes in UI policy. We characterize the optimal history-dependent UI policy. We find that, all else equal, the optimal benefit is decreasing in current productivity and decreasing in current unemployment. Optimal benefits are therefore lowest when current productivity is high and current unemployment is high. The optimal path of benefits reacts non-monotonically to a productivity shock. Following a drop in productivity, benefits initially rise in order to provide short-run relief to the unemployed and stabilize wages, but then fall significantly below their pre-recession level, in order to speed up the subsequent recovery. Under the optimal policy, the path of benefits is pro-cyclical overall. As compared to the existing US UI system, the optimal history-dependent benefits smooth cyclical fluctuations in unemployment and deliver non-negligible welfare gains.Unemployment Insurance, Business Cycles, Optimal Policy, Search and Matching

Pro-cyclical Unemployment Benefits? Optimal Policy in an Equilibrium Business Cycle Model

We study the optimal provision of unemployment insurance (UI) over the business cycle. We use an equilibrium search and matching model with aggregate shocks to labor productivity, incorporating risk-averse workers, endogenous worker search effort decisions, and unemployment benefit expiration. We characterize the optimal UI policy, allowing both the benefit level and benefit duration to depend on the history of past aggregate shocks. We find that the optimal benefit is decreasing in current productivity and decreasing in current unemployment. Following a drop in productivity, benefits initially rise in order to provide short-run relief to the unemployed and stabilize wages, but then fall significantly below their pre-recession level, in order to speed up the subsequent recovery. Under the optimal policy, the path of benefits is pro-cyclical overall. As compared to the existing US UI system, the optimal history-dependent benefits smooth cyclical fluctuations in unemployment and deliver substantial welfare gains.Unemployment Insurance, Business Cycles, Optimal Policy, Search and Matching

Macroeconomic Effects of Bankruptcy & Foreclosure Policies

Bankruptcy laws govern consumer default on unsecured credit. Foreclosure laws regulate default on secured mortgage debt. I investigate to what extent differences in foreclosure and bankruptcy laws can jointly explain variation in default rates across states. I construct a general equilibrium model where heterogeneous infinitely-lived households have access to unsecured borrowing and can finance housing purchases with mortgages. Households can default separately on both types of debt. The model is calibrated to match national foreclosure and bankruptcy rates and aggregate statistics related to household net worth and debt. The model can account for 83% of the variation in bankruptcy rates due to differences in bankruptcy and foreclosure law. I find that more generous homestead exemptions raise the cost of unsecured borrowing. Households in states with high exemptions therefore hold less unsecured and more mortgage debt compared to low exemption states, which leads to lower bankruptcy rates but higher foreclosure rates. The model also predicts recourse results in higher bankruptcy rates and a higher coincidence of foreclosure and bankruptcy. I use the model to evaluate how proposed and implemented changes to bankruptcy policy affect default rates and welfare. The 2005 Bankruptcy Abuse Prevention and Consumer Protection Act yields large welfare gains (1% consumption equivalent variation) but results in increases in both foreclosure and bankruptcy rates. I find that implementing the optimal joint foreclosure and bankruptcy policy, which is characterized by no-recourse mortgages and a homestead exemption equal to one quarter of median income, yields modest welfare gains (0.3% consumption equivalent variation).Bankruptcy, Foreclosure, Housing, Default Risk, Household Debt

Case Study of Unemployment Insurance Reform in North Carolina

In July 1, 2013 unemployed workers in North Carolina lost access to all federally ?nanced unemployment bene?t extensions. In this document, the authors collect and describe available evidence on the performance of the labor market in North Carolina following this reform

Housing and the Macroeconomy: The Role of Bailout Guarantees for Government Sponsored Enterprises

This paper evaluates the macroeconomic and distributional effects of government bailout guarantees for Government Sponsored Enterprises (such as Fannie Mae and Freddy Mac) in the mortgage market. In order to do so we construct a model with heterogeneous, infinitely lived households and competitive housing and mortgage markets. Households have the option to default on their mortgages, with the consequence of having their homes foreclosed. We model the bailout guarantee as a government provided and tax-financed mortgage interest rate subsidy. We find that eliminating this subsidy leads to substantially lower equilibrium mortgage origination and increases aggregate welfare, but has little effect on foreclosure rates and housing investment. The interest rate subsidy is a regressive policy: eliminating it benefits low-income and low-asset households who did not own homes or had small mortgages, while lowering the welfare of high-income, high-asset households.

Competitive Advantage for Multiple-Memory Strategies in an Artificial Market

We consider a simple binary market model containing $N$ competitive agents. The novel feature of our model is that it incorporates the tendency shown by traders to look for patterns in past price movements over multiple time scales, i.e. {\em multiple memory-lengths}. In the regime where these memory-lengths are all small, the average winnings per agent exceed those obtained for either (1) a pure population where all agents have equal memory-length, or (2) a mixed population comprising sub-populations of equal-memory agents with each sub-population having a different memory-length. Agents who consistently play strategies of a given memory-length, are found to win more on average -- switching between strategies with different memory lengths incurs an effective penalty, while switching between strategies of equal memory does not. Agents employing short-memory strategies can outperform agents using long-memory strategies, even in the regime where an equal-memory system would have favored the use of long-memory strategies. Using the many-body `Crowd-Anticrowd' theory, we obtain analytic expressions which are in good agreement with the observed numerical results. In the context of financial markets, our results suggest that multiple-memory agents have a better chance of identifying price patterns of unknown length and hence will typically have higher winnings.Comment: Talk to be given at the SPIE conference on Econophysics and Finance, in the International Symposium 'Fluctuations and Noise', 23-26 May 2005 in Austin, Texa

Reducing the duration of unemployment benefits as arecession progresses can speed economic recovery

In the aftermath of the Great Recession, millions of Americans received extensions to their unemployment benefits – in some cases extending them to 99 weeks. At the end of 2013, these extended benefits expired, leading many to call on Congress to reauthorize their extension. But does extending unemployment benefits make sound economic sense? In new research, Stanislav Rabinovich and Kurt Mitman argue that the government was correct to rein in the duration of benefits. They write that reducing the duration of benefits helps the unemployed to find jobs faster, and leads to much less volatile unemployment
