Productivity Trends in Europe: Implications for Real Exchange Rates, Real Interest Rates, and Inflation 总被引:1,自引:0,他引:1
Matthew Canzoneri Robert Cumby Behzad Diba & Gwen Eudey 《Review of International Economics》2002,10(3):497-516
The paper examines a long–run (neoclassical) framework in which differences in productivity growth across sectors and countries lead to inflation differentials. In a currency union, these inflation differentials imply cross–country differentials in real interest rates. The authors estimate the likely size of these differentials for European Union countries, discuss the potential costs of persistent inflation differentials, and comment on the conflicts they may cause within Economic and Monetary Union (EMU). The analytical framework is a variant of the Balassa–Samuelson "productivity hypotheisis," which relates sectoral productivity trends to trends in the relative price of home goods. 相似文献

Models that assume bonds denominated in different currencies are perfect substitutes can not explain certain empirical puzzles: the exchange rate volatility puzzle is that these models can not explain the observed volatility in real and nominal exchange rates; the Backus-Smith puzzle is that these models can not explain the observed low correlation between real exchange rates and the ratio of home to foreign consumption; the Backus-Kehoe-Kydland puzzle is that these models can not explain the observed low correlation between home and foreign consumption; and finally, the uncovered interest parity puzzle is that these models can not explain the observed deviations from that parity. These long standing puzzles make the models harder to defend. In this paper, we present a symmetric two country portfolio balance model in which home and foreign bonds are imperfect substitutes for money in each country’s transactions technology; this of course makes home and foreign bonds imperfect substitutes for each other. Our calibrated model is capable of addressing the Backus-Smith puzzle and the Backus-Kehoe-Kydland puzzle. It does not fully resolve the exchange rate volatility puzzle, but it makes some headway. And finally it generates deviations from uncovered interest parity, though by some estimates these deviations are not large enough to be consistent with the data. 相似文献

Euler equations and money market interest rates: A challenge for monetary policy models 总被引:1,自引:0,他引:1

Standard macroeconomic models equate the money market rate targeted by the central bank with the interest rate implied by a consumption Euler equation. We use U.S. data to calculate the interest rates implied by Euler equations derived from a number of specifications of household preferences. Correlations between these Euler equation rates and the Federal Funds rate are generally negative. Regression results and impulse response functions imply that the spreads between the Euler equation rates and the Federal Funds rate are systematically linked to the stance of monetary policy. Our findings pose a fundamental challenge for models that equate the two. 相似文献

Devaluations and fiscal retrenchments coming from developed countries are buffeting less developed countries. Many emerging market countries have adopted inflation targeting as “best practice,” but now they are being advised to enhance their inflation targeting regimes with foreign exchange intervention. Here we use a DSGE model to tell some cautionary tales about this advice. A Taylor rule guides interest rate setting, while foreign exchange interventions are used as a second tool of monetary policy. These interventions are effective in our model since domestic and key currency bonds are imperfect substitutes. We derive optimal (Ramsey) intervention policies in response to foreign devaluations and fiscal retrenchments, and find that they are rather complex. So, we compare the optimal responses to policies that simply smooth real or nominal exchange rate movements. Our results suggest that discretion may be the better part of valor: pure inflation targeting may come closer to the optimal policy than exchange rate smoothing. A secondary result may also be of some interest: foreign exchange interventions have a stronger impact on inflation and output in an inflation targeting regime than do sterilized interventions; the Taylor rule augments the effects of a given intervention. 相似文献

What determines the cyclical behavior of aggregate inflation and regional inflation differentials? The answer has strong implications for monetary policy and in Europe for the Stability and Growth Pact. In the United States, inflation rates move pro-cyclically, and across the Euro Area, inflation differentials are positively correlated with growth differentials. This suggests that demand shocks are the primary determinants of the cyclical behavior of aggregate inflation and regional inflation differentials. In this paper, we discuss New Keynesian explanations of these correlations, and we argue that demand shocks are either missing or inadequately modeled in the in typical New Keynesian model. 相似文献

The paper develops a two-step estimator for use in rational-expectations models with autocorrelated residuals and predetermined, but not strictly exogenous, instruments. The estimator extends the applicability of McCallum's (1976) error-in-variablesapproach to estimating such models, and is asymptotically efficient in a class of intrumental-variables estimators. As an application we use instrumental-variables techniques to estimate Taylor's (1979) rational-expectations macroeconomic model of the United States. 相似文献

This paper finds that the introduction of dual exchange rates gives the monetary authority greater independence from external constraints than it would otherwise enjoy. The monetary authority is able to influence the level of aggregate demand in the short run and to sterilize the effects of temporary foreign disturbances. In addition, the paper finds that dual rates insulate the domestic economy fully from foreign interest rate changes but do not provide insulation from speculative disturbances. 相似文献

Fiscal Discipline and Exchange Rate Systems 总被引:1,自引:0,他引:1
Matthew B. Canzoneri Robert E. Cumby & Behzad T. Diba 《Economic journal (London, England)》2001,111(474):667-690
A new 'fiscal' theory of price determination has implications for exchange rate systems and common currency areas. We show that deeper monetary integration requires the discipline of a Ricardian regime ; that is, the government must guarantee fiscal solvency for any sequence of prices or exchange rates. Particularly striking results are that a currency peg is not credible without the discipline of a Ricardian regime, and a common currency area is not viable if fiscal policy in two (or more) of the countries in the union is Non-Ricardian. Interestingly, constraints written into the Maastricht Treaty are sufficient for a Ricardian regime. 相似文献
