Gambling for redemption and self-fulfilling debt crises
We develop a model for analyzing the sovereign debt crises of 2010?2012 in the Eurozone. The government sets its expenditure-debt policy optimally. The need to sell large quantities of bonds every period leaves the government vulnerable to self-fulfilling crises in which investors, anticipating a crisis, are unwilling to buy the bonds, thereby provoking the crisis. In this situation, the optimal policy of the government is to reduce its debt to a level where crises are not possible. If, however, the economy is in a recession where there is a positive probability of recovery in fiscal ...

A primer on social security systems and reforms
This article reviews the characteristics of different social security systems. Many configurations arise depending on the nature of a system?s funding and determination of benefits. Many reforms propose changing the U.S. Social Security system. The authors focus their analysis of the transition from a pay-as-you-go to a fully funded system. They argue that the key component of any reform is the treatment of the implicit liabilities of a country?s social security system. The welfare gains accruing to some cohorts as a result of such reforms usually stem from either a partial or complete ...

Modeling great depressions: the depression in Finland in the 1990s
This paper is a primer on the great depressions methodology developed by Cole and Ohanian (1999, 2007) and Kehoe and Prescott (2002, 2007). We use growth accounting and simple dynamic general equilibrium models to study the depression that occurred in Finland in the early 1990s. We find that the sharp drop in real GDP over the period 1990?93 was driven by a combination of a drop in total factor productivity (TFP) during 1990?92 and of increases in taxes on labor and consumption and increases in government consumption during 1989?94, which drove down hours worked in Finland. We attempt to ...

Implications of Increasing College Attainment for Aging in General Equilibrium
We develop and calibrate an overlapping generations general equilibrium model of the U.S. economy with heterogeneous consumers who face idiosyncratic earnings and health risk to study the implications of exogenous trends in increasing college attainment, decreasing fertility, and increasing longevity between 2005 and 2100. While all three trends contribute to a higher old age dependency ratio, increasing college attainment has different macroeconomic implications because it increases labor productivity. Decreasing fertility and increasing longevity require the government to increase the ...

Generational policy and the macroeconomic measurement of tax incidence
In this paper we show that the generational accounting framework used in macroeconomics to measure tax incidence can, in some cases, yield inaccurate measurements of the tax burden across age cohorts. This result is very important for policy evaluation, because it shows that the selection of tax policies designed to change generational imbalances could be misleading. We illustrate this problem in the context of a Social Security reform where we show how fiscal policy can affect the intergenerational gap across cohorts without impacting the distribution of welfare. We provide a more accurate ...

Chronic sovereign debt crises in the Eurozone, 2010-2012
Two years after the rescue package for Greece provided by the European Union and the International Monetary Fund in May 2010, sovereign debt crises continue to threaten a growing number of countries in the eurozone. We develop a theory for analyzing these crises based on the research of Cole and Kehoe (1996, 2000) and Conesa and Kehoe (2012). In this theory, the need to frequently sell large quantities of bonds leaves a country vulnerable to sovereign debt crisis. This vulnerability provides a strong incentive to the country?s government to run surpluses to pay down its debt to a level where ...

Is It Too Late to Bail Out the Troubled Countries in the Eurozone?
In January 1995, U.S. President Bill Clinton organized a bailout for Mexico that imposed penalty interest rates and induced the Mexican government to reduce its debt, ending the debt crisis. Can the Troika (European Commission, European Central Bank, and International Monetary Fund) organize similar bailouts for the troubled countries in the Eurozone? Our analysis suggests that debt levels are so high that bailouts with penalty interest rates could induce the Eurozone governments to default rather than reduce their debt. A resumption of economic growth is one of the few ways that the Eurozone ...

Optimal fiscal policy in the design of Social Security reforms
The quantitative macroeconomics literature has documented that in the basic Overlapping Generations model a privatization of the social security system, going from a Pay-As-You-Go to a Fully Funded system, generates large long run welfare gains at the cost of substantial welfare losses for initial generations. We propose an alternative to previous literature. In this paper we maximize over the entire policy space, following the optimal fiscal policy approach, rather than comparing alternative policy paths one to one. That is, policies are chosen as part of the optimal design of a social ...

Productivity, Taxes, and Hours Worked in Spain: 1970-2015
In the early 1970s, hours worked per working-age person in Spain were higher than in the United States. Starting in 1975, however, hours worked in Spain fell by 40 percent. We find that 80 percent of the decline in hours worked can be accounted for by the evolution of taxes in an otherwise standard neoclassical growth model. Although taxes play a crucial role, we cannot argue that taxes drive all of the movements in hours worked. In particular, the model underpredicts the large decrease in hours in 1975?1986 and the large increase in hours in 1994?2007. The lack of productivity growth in ...

Optimal response to a transitory demographic shock in Social Security financing
The authors consider a transitory demographic shock that affects negatively the financing of retirement pensions-that is, workers either would have to pay more or retirees would receive less. In contrast to the existing literature, the authors endogenously determine optimal policies rather than explore the implications of exogenous parametric responses. Their approach identifies optimal strategies of the Social Security Administration to guarantee the financial sustainability of existing retirement pensions in a Pareto-improving way. Hence, no cohort will pay the cost of the demographic ...
