MoNK: Mortgages in a New-Keynesian Model
We propose a tractable framework for monetary policy analysis in which both short- and long-term debt affect equilibrium outcomes. This objective is motivated by observations from two literatures suggesting that monetary policy contains a dimension affecting expected future interest rates and thus the costs of long-term financing. In New-Keynesian models, however, long-term loans are redundant assets. We use the model to address three questions: what are the effects of statement vs. action policy shocks; how important are standard New- Keynesian vs. cash flow effects in their transmission; ...

International business cycles: theory vs. evidence
This article reviews recent work comparing properties of international business cycles with those of dynamic general equilibrium models. Two discrepancies between theory and data are described. One concerns the correlation across countries of fluctuations in consumption, output, and productivity: in the data, the output correlation is generally the largest; in theoretical economies, however, for a wide range of parameter values, the consumption correlation is the largest. The other discrepancy concerns relative price movements: the standard deviation of the terms of trade is considerably ...

On the record: putting people into economic policy: a conversation with Finn Kydland
Finn Kydland, a Dallas Fed consultant since 1994, shared the 2004 Nobel Prize in economics with Edward C. Prescott for their groundbreaking work incorporating decisionmaking by individuals, households and firms into economic models.

Is the business cycle of Argentina "different?"
Despite the relative success of Real Business Cycle (RBC) models to replicate key moments of the business cycles of the United States and several European countries, economic research in Latin America tends to take the more traditional view that monetary factors play a predominant role in the economic fluctuations of countries in that part of the world. The different theoretical approach is often justified on the grounds that business cycles in Latin America are "different." However, few comparative studies have analyzed the relevant difference between the business cycles of Latin America ...

International real business cycles
We ask whether a two-country real business cycle model can account simultaneously for domestic and international aspects of business cycles. With this question in mind, we document a number of discrepancies between theory and data. The most striking discrepancy concerns the correlations of consumption and output across countries. In the data, outputs are generally more highly correlated across countries than consumptions. In the model we see the opposite.

Argentina's capital gap puzzle
Argentinas GDP per working age person in 2003 was about the same as it was twenty years earlier and around fifteen percent below trend. By international standards that has been a dismal performance whose ultimate sources are important to uncover to eventually reverse that countrys seemingly secular decline. The purpose of this paper is precisely to take a first step towards that understanding. To that effect, we examine Argentinas recent growth experience, which includes two deep recessions and a recovery, with the lens of a neoclassical growth model that takes total factor productivity as ...

Home production meets time-to-build
An innovation in this paper is to introduce a time-to-build technology for the production of market capital into a model with home production. The paper?s main finding is that the two anomalies that have plagued all household production models?the positive correlation between business and household investment, and household investment leading business investment over the business cycle?are resolved when time-to-build is added.

Monetary policy, taxes and the business cycle
This paper analyzes the interaction of inflation with the tax code and its contribution to aggregate fluctuations. We find significant effects operating through the tax on realized nominal capital gains. A tax on nominal bond income magnifies these effects. Our innovation is to combine monetary policy shocks with non-indexed taxes in a model where the central bank implements policy using an interest rate rule. Monetary policy had important effects on the behavior of the business cycle before 1980 because policymakers did not exert effective control over inflation. Monetary policy reform ...

Relative price movements in dynamic general equilibrium models of international trade
We examine the behavior of international relative prices from the perspective of dynamic general equilibrium theory, with particular emphasis on the variability of the terms of trade and the relation between the terms of trade and net exports. We highlight aspects of the theory that are critical in determining these properties, contrast our perspective with those associated with the Marshall-Lerner condition and the Harberger-Laursen-Metzler effect, and point out features of the data that have proved difficult to explain within existing dynamic general equilibrium models.
