The relationship between exchange rates and inflation targeting revisited
For decades, the exchange rate was at the center of macroeconomic policy debates in emerging markets. Many countries used the nominal exchange rate to bring down inflation, –others—mostly in Latin America—used the exchange rate to implicitly tax the export sector. Currency crises were common and usually ...
Commodity prices and macroeconomic policy: and overview
World commodity prices and their macroeconomic impact especially on emerging economies have long been a main concern in economic research. Decades ago the Prebisch-Singer hypothesis of secularly deteriorating terms of trade (Prebisch 1950 Singer 1950) was the subject of intense debate and became a ...
Indexation, inflationary inertia, and the sacrifice coeficient
When inflation is chronic, firms develop indexation practices that automatically tie the growth of prices, wages, and other contracts to the performance of some comprehensive price index. The microeconomic advantages of indexation are evident and derive from the immunization of the relative price ...
Endogenous exchange-rate pass-through and self-validating exchange rate regimes
A long-standing question in open macroeconomics concerns the choice of currency denomination of nominal prices and contracts. A firm serving the export market may choose to set prices in its domestic currency in the currency of the market of destination or in a vehicle currency possibly indexing these ...
Corporate saving in global rebalancing
The increase in global imbalances in the last decade posed a theoretical challenge for international macroeconomics. Why did some less developed countries with a higher need for capital like China lend to richer countries? The inconsistency of standard dynamic open-economy models with actual global ...
Optimal inflation stabilization in a medium-scale macroeconomic model
What is the optimal monetary policy, and how can the central bank implement it? Both questions have been extensively studied, but always in the context of simple theoretical structures, which by design are limited in their ability to account for actual observed business cycle fluctuations. This article ...
Fiscal policy and macroeconomic performance: an overview
After two decades of relative neglect fiscal policy is back at the center of the economics research agenda. The fiscal developments around the global financial crisis of 2007–09 are undoubtedly a major factor behind that comeback. The large fiscal stimulus packages adopted by many countries in the ...
General equilibrium dynamics of external shocks and policy changes in Chile
This paper explores Chile’s macroeconomic dynamics with the help of a general equilibrium model parameterized for the Chilean economy. The model is based on microanalytic foundations, and its basic relations are derived from intertemporal optimization by a group of forward-looking agents endowed with ...
A toolkit for analyzing alternative policies in the chilean economy
As noted by Leeper (1995) “the business pages of leading newspapers give the impression that the effects of alternative monetary policies on the macroeconomy are well understood and predictable.” They tend “to write with great certainty that when the monetary authority raises interest rates it slows ...
The effects of business cycles on growth
This paper explores the links between business cycles and long-run growth. Although it is clear from a theoretical point of view that both of these phenomena are driven by the same macroeconomic variables, the interaction between economic fluctuations and growth has been largely ignored in the academic ...
