Self-Fulfilling Debt Crises, Revisited: The Art of the Desperate Deal
We revisit self-fulfilling rollover crises by introducing an alternative equilibrium selection that involves bond auctions at depressed but strictly positive equilibrium prices, a scenario in line with observed sovereign debt crises. We refer to these auctions as ?desperate deals?, the defining feature of which is a price schedule that makes the government indifferent to default or repayment. The government randomizes at the time of repayment, which we show can be implemented in pure strategies by introducing stochastic political payoffs or external bailouts. Quantitatively, auctions at ...

What about Japan?
As a result of the BoJ's large-scale asset purchases, the consolidated Japanese government borrows mostly at the floating rate from households and invests in longer-duration risky assets to earn an extra 3% of GDP. We quantify the impact of Japan's low-rate policies on its government and households. Because of the duration mismatch on the government balance sheet, the government's fiscal space expands when real rates decline, allowing the government to keep its promises to older Japanese households. A typical younger Japanese household does not have enough duration in its portfolio to ...

The Great Depression in the United States from a neoclassical perspective
Can neoclassical theory account for the Great Depression in the United States?both the downturn in output between 1929 and 1933 and the recovery between 1934 and 1939? Yes and no. Given the large real and monetary shocks to the U.S. economy during 1929?33, neoclassical theory does predict a long, deep downturn. However, theory predicts a much different recovery from this downturn than actually occurred. Given the period?s sharp increases in total factor productivity and the money supply and the elimination of deflation and bank failures, theory predicts an extremely rapid recovery that ...

The macroeconomic effects of world trade in financial assets
This article analyzes some of the potential effects of increased international financial integration within a simple two-country model. In the model, the article considers a switch in the menu of internationally traded financial securities from bonds to complete contingent claims and examines the impact of this switch on the stochastic properties, including the cross-country correlations, of standard macroeconomic aggregates like output, consumption, and labor effort, as well as the trade balance.

Incorporating concern for relative wealth into economic models
This article develops a simple model that captures a concern for relative standing, or status. This concern is instrumental, in the sense that individuals do not get utility directly from their relative standing, but, rather, the concern is induced because their relative standing affects their consumption of standard commodities. The article investigates the consequences of a concern for relative wealth in models in which individuals are making labor/leisure decisions. The analysis shows how individuals' decisions are affected by the aggregate income distribution and how the concern for ...

Why doesn’t technology flow from rich to poor countries?
What is the role of a country?s financial system in determining technology adoption? To examine this, a dynamic contract model is embedded into a general equilibrium setting with competitive intermediation. The terms of finance are dictated by an intermediary?s ability to monitor and control a firm?s cash flow, in conjunction with the structure of the technology that the firm adopts. It is not always profitable to finance promising technologies. A quantitative illustration is presented where financial frictions induce entrepreneurs in India and Mexico to adopt less-promising ventures than in ...

Direct investment: a doubtful alternative to international debt
The paper considers a model in which private foreign investors make direct long-lived capital investments in a small developing country that is subject to stochastic shocks to production. Depending upon the preferences of the host country, we find that expropriation can occur because of either desperation or opportunism. We show that under reasonable assumptions, increased investment makes expropriation less likely to occur and that the level of investment chosen by atomistic foreign investors may be nonoptimal.

Implications of heterogeneity in preferences, beliefs and asset trading technologies for the macroeconomy
This paper analyzes and computes the equilibria of economies with large numbers of heterogeneous agents who have different asset trading technologies, preferences, and beliefs. We illustrate the value of our method by using it to evaluate the implications of these heterogeneities through several quantitative exercises.

Aggregate returns to scale: why measurement is imprecise
The extent to which there are aggregate returns to scale at the level of aggregate production has important implications both for the types of shocks generating business cycles and for optimal policy. However, prior attempts to measure the extent of these returns using instrumental variable techniques have yielded quite imprecise estimates. In this article, we show that the production shocks implied by a range of returns to scale that encompasses both large increasing returns and large decreasing returns are almost identical. This makes clear that there is a fundamental reason for the ...

Zero nominal interest rates: why they're good and how to get them
This study shows that in a standard one-sector neoclassical growth model, in which money is introduced with a cash-in-advance constraint, zero nominal interest rates are optimal. Milton Friedman argued in 1969 that zero nominal rates are necessary for efficient resource allocation. This study shows that they are not only necessary but sufficient. The study also characterizes the monetary policies that will implement zero rates. The set of such policies is quite large. The only restriction these policies must satisfy is that asymptotically money shrinks at a rate no greater than the rate of ...
