Working Paper
Optimal Fiscal Policies under Market Failures

The aggregate capital stock in a nation can be overaccumulated for many different reasons. This paper studies which policy or policy mix is more effective in achieving the socially optimal (modified golden rule) level of aggregate capital stock in an infinite-horizon heterogeneous-agents incomplete-markets economy where capital may be over-accumulated for two distinct reasons: (i) precautionary savings and (ii) production externalities. By solving the Ramsey problem analytically along the entire transitional path, we show that public debt and capital taxation play very distinct roles in ...

Frictional Intermediation in Over-the-Counter Markets

We extend Duffie, G?arleanu, and Pedersen?s (2005) search theoretic model of over-the-counter (OTC) asset markets, allowing for a decentralized inter-dealer market with arbitrary heterogeneity in dealers? valuations or inventory costs. We develop a solution technique that makes the model fully tractable and allows us to derive, in closed form, theoretical formulas for key statistics analyzed in empirical studies of the intermediation process in OTC markets. A calibration to the market for municipal securities reveals that the model can generate trading patterns and prices that are ...

A tale of two commitments: equilibrium default and temptation

I construct the life-cycle model with equilibrium default and preferences featuring temptation and self-control. The model provides quantitatively similar answers to positive questions such as the causes of the observed rise in debt and bankruptcies and macroeconomic implications of the 2005 bankruptcy reform, as the standard model without temptation. However, the temptation model provides contrasting welfare implications, because of overborrowing when the borrowing constraint is relaxed. Specifically, the 2005 bankruptcy reform has an overall negative welfare effect, according to the ...

Estimating Aggregate Fiscal Multipliers from Local Data

Variations among regions in their responses to economic policies can be used to estimate the effects of those policies at the national level while minimizing or eliminating issues of reverse causation. Recent research has employed county-level data to look at the effects of federal government spending ? in particular, the 2009?12 stimulus ? on aggregate consumption.

Assessing Bankruptcy Reform in a Model with Temptation and Equilibrium Default

A life-cycle model with equilibrium default in which agents with and without temptation coexist is constructed to evaluate the 2005 bankruptcy law reform. The calibrated model indicates that the 2005 reform reduces bankruptcies, as seen in the data, and improves welfare, as lower default premia allows better consumption smoothing. A counterfactual reform of changing income garnishment rate is also investigated. Interesting contrasting welfare effects between two types of agents emerge. Agents with temptation prefer a lower garnishment rate as tighter borrowing constraint prevents them from ...

Watering a lemon tree: heterogeneous risk taking and monetary policy transmission

We build a general equilibrium model with financial frictions that impede monetary policy transmission. Agents with heterogeneous productivity can increase investment by levering up, which increases liquidity risk due to maturity transformation. In equilibrium, more productive agents choose higher leverage than less productive agents, which exposes the more productive agents to greater liquidity risk and makes their investment less responsive to interest rate changes. When monetary policy reduces interest rates, aggregate investment quality deteriorates, which blunts the monetary stimulus and ...

Working Paper
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 ...

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 ...

The Heterogeneous Effects of Government Spending : It’s All About Taxes

This paper investigates how government spending multipliers depend on the distribution of taxes across households. We exploit historical variations in the financing of spending in the U.S. since 1913 to show that multipliers are positive only when financed with more progressive taxes, and zero otherwise. We rationalize this finding within a heterogeneous-household model with indivisible labor supply. The model results in a lower labor responsiveness to tax changes for higher-income earners. In turn, spending financed with more progressive taxes induces a smaller crowding-out, and thus larger ...

Optimal Public Debt with Life Cycle Motives

Public debt can be optimal in standard incomplete market models with infinitely lived agents, since the associated capital crowd-out induces a higher interest rate. The higher interest rate encourages individuals to save and, hence, better self-insure against idiosyncratic labor earnings risk. Even though individual savings behavior is a crucial determinant of the optimality of public debt, this class of economies abstracts from empirically observed life cycle savings patterns. Thus, this paper studies how incorporating a life cycle affects optimal public debt. We find that while the ...
