Insurance and Inequality with Persistent Private Information

This paper studies the implications of optimal insurance provision for long-run welfare and inequality in economies with persistent private information. We consider a model in which a principal insures an agent whose privately observed endowment follows an ergodic, finite Markov chain. The optimal contract always induces immiseration: the agent’s consumption and utility decrease without bound. Under positive serial correlation, the optimal contract also features backloaded high-powered incentives: the sensitivity of the agent’s utility with respect to his report increases without bound. ...

Fiscal Dominance

Who prevails when fiscal and monetary authorities disagree about the value of public expenditure and how much to discount the future? When the fiscal authority sets debt as its main policy instrument it achieves fiscal dominance, rendering the preferences of the central bank, and thus its independence, irrelevant. When the central bank sets the nominal interest rate it renders fiscal impatience (its debt bias) irrelevant, but still faces its expenditure bias. I find that the expenditure bias has a major impact on welfare through higher public spending, while the effect on other policies is ...

Pandemic Lockdown: The Role of Government Commitment

This paper studies lockdown policy in a dynamic economy without government commitment. Lockdown imposes a cap on labor supply, which improves health prospects at the cost of economic output and consumption. A government would like to commit to the extent of future lockdowns in order to guarantee an economic outlook that supports efficient levels of investment into intermediate inputs. However, such a commitment is not credible, since investments are sunk at the time when the government chooses a lockdown. As a result, lockdown under lack of commitment deviates from the optimal policy. Rules ...

Optimal monetary and fiscal policy at the zero lower bound in a small open economy

We investigate open economy dimensions of optimal monetary and fiscal policy at the zero lower bound (ZLB) in a small open economy model. At positive interest rates, the trade elasticity has negligible effects on optimal policy. In contrast, at the ZLB, the trade elasticity plays a key role in optimal policy prescriptions. The way in which the trade elasticity shapes policy depends on the government's ability to commit. Under discretion, the increase in government spending at the ZLB depends critically on the trade elasticity. Under commitment, the difference between future and current ...

An investigation of the gains from commitment in monetary policy

This paper proposes a simple framework for analyzing a continuum of monetary policy rules characterized by differing degrees of credibility, in which commitment and discretion become special cases of what we call quasi commitment. The monetary policy authority is assumed to formulate optimal commitment plans, to be tempted to renege on them, and to succumb to this temptation with a constant exogenous probability known to the private sector. By interpreting this probability as a continuous measure of the (lack of) credibility of the monetary policy authority, we investigate the welfare effect ...

A Quantitative Theory of Time-Consistent Unemployment Insurance

During recessions, the U.S. government substantially increases the duration of unemployment insurance (UI) benefits through multiple extensions. This paper seeks to understand the incentives driving these increases. Because of the trade-off between insurance and job search incentives, the classic time-inconsistency problem arises. During recessions, the U.S. government substantially increases the duration of unemployment insurance (UI) benefits through multiple extensions. This paper seeks to understand the incentives driving these extensions. Because of the trade-off between insurance and ...

Optimal Unemployment Insurance Requirements

In the US, unemployed workers must satisfy two requirements to receive unemployment insurance (UI): a tenure requirement that stipulates the minimum qualifying work spell and a monetary requirement that determines a past minimum wage. This paper develops a heterogeneous agents model with history-dependent UI benefits in order to quantitatively obtain an optimal UI program design. We first conduct an empirical analysis using the discontinuity of UI rules at state borders and find that both the monetary and the tenure requirement reduce unemployment. The monetary requirement decreases the ...

Is optimal monetary policy always optimal?

No. And not only for the reason you think. In a world with multiple inefficiencies the single policy tool the central bank has control over will not undo all inefficiencies; this is well understood. We argue that the world is better characterized by multiple ine?ciencies and multiple policy makers with various objectives. Asking the policy question only in terms of optimal monetary policy effectively turns the central bank into the residual claimant of all policy and gives the other policymakers a free hand in pursuing their own goals. This further worsens the tradeoffs faced by the central ...

Decentralization and Overborrowing in a Fiscal Federation

We build an infinite horizon equilibrium model of fiscal federation, where anticipation of transfers from the central government creates incentives for local governments to overborrow. Absent commitment, the central government over-transfers, which distorts the central-local distribution of resources. Applying the model to fiscal decentralization, we find when decentralization widens local governments? fiscal gap, borrowings by both local and central governments rise. Quantitatively, fiscal decentralization accounts for from 19 percent to 40 percent of changes in general government debt in ...

Preventive vs. Curative Medicine: A Macroeconomic Analysis of Health Care over the Life Cycle

This paper studies differences in health care usage and health outcomes between low- and high-income individuals. 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 medical spending of the poor surpasses that of the rich by 25%. In addition, low-income individuals are less likely to incur any medical expenditures in a given year, yet, when they do, their expenses are more likely to be extreme. To account for these facts, I develop and estimate a life-cycle model of two ...
