Macroeconomic Fluctuations in Sub-Saharan Africa

The sources of macroeconomic fluctuations in sub-Saharan Africa are examined by comparing the CFA franc countries with the non--CFA franc countries. External shocks, especially terms of trade shocks, appear to have a greater influence on fluctuations of output and the real exchange rate in CFA franc countries. This result does not appear to be associated with differences in the economic structure but may reflect the fixed exchange rate regime, which does not (partially) buffer these countries from external shocks. Macroeconomic fluctuations in non--CFA franc countries are similar to those in other developing countries, particularly in Latin America.

Are Business Cycles Different in Asia and Latin America

This paper compares business cycles in Asia and in Latin America using structural vector autoregression analysis with panel data. The evidence for countries in these regions suggests that (i) the main source of output fluctuations is supply shocks, even in the short run; (ii) the real exchange rate is driven mostly by fiscal shocks; and (iii) terms of trade shocks are important for trade balance fluctuations but not for output or real exchange rate fluctuations. However, in Latin America, as opposed to Asia, output is affected more by external and domestic demand shocks.

The Sources of Macroeconomic Fluctuations in Developing Countries: Brazil and Korea

This paper studies the sources of macroeconomic fluctuations in developing countries using a structural VAR approach. Identification of the sources is achieved using long-run restrictions derived from a theoretical model of a small open economy encompassing a large number of macroeconomic paradigms; the short-run dynamics are unrestricted. This framework is applied to Brazil and Korea. The results confirm that supply shocks are the main source of GDP fluctuations, even in the short run. Aggregate demand shocks are shown to be important in the short run in Brazil, but not in Korea. External shocks explain a small fraction of the variance of output, whereas the real exchange rate is driven mainly by fiscal shocks. Nominal shocks appear to have little impact on output and the real exchange rate.

Disintermediation and Monetary Transmission in Canada

This paper studies changes in Canadas monetary policy transmission, associated with the important changes in financial structure experienced in the 1990s, using two methodologies. First, VAR models show a clear break in monetary transmission beginning in 1988, after changes in financial regulation initiated the process of financial disintermediation. Second, estimates of the interest rate elasticity of aggregate demand in IS equations increase in the 1990s, suggesting that the systematic component of monetary policy has become more relevant. The ratio of direct to indirect finance, a measure of disintermediation, contributes to explain changes in the interest rate elasticity, suggesting an increased effectiveness of monetary policy associated with a larger use of market-based sources of finance.

Potential Output Growth in Emerging Market Countries: The Case of Chile

This paper estimates potential output and the sources of growth in Chile during 1970-96. Actual output is cointegrated with the quality-adjusted measures of capital and labor, and constant returns to scale cannot be rejected. The estimates of potential output show a positive output gap in the years when the Chilean economy was deemed to be overheated. In 1986-90, the quality-adjusted labor variable explains close to 60 percent of the growth rate of GDP, while during 1991-95 capital formation plays a dominant role. The contribution of TFP growth in Chile is relatively small, but, based on a comparison with European and East Asian experiences, it is expected to increase in the medium term.

Monetary and Macroprudential Policies to Manage Capital Flows

We study interactions between monetary and macroprudential policies in a model with nominal and financial frictions. The latter derive from a financial sector that provides credit and liquidity services that lead to a financial accelerator-cum-fire-sales amplification mechanism. In response to fluctuations in world interest rates, inflation targeting dominates standard Taylor rules, but leads to increased volatility in credit and asset prices. The use of a countercyclical macroprudential instrument in addition to the policy rate improves welfare and has important implications for the conduct of monetary policy. “Leaning against the wind” or augmenting a standard Taylor rule with an argument on credit growth may not be an effective policy response.

On gradual disinflation, the real exchange rate, and the current account

Abstract We study the effects of a credible, gradual exchange-rate-based disinflation program in a two sector economy. After an initial exchange rate depreciation, the reductions in the rate of devaluation reduce the monetary wedge generated by the cash-in-advance constraint, leading to a gradual increase in absorption that yields progressive real exchange rate appreciations and current account deficits. An initial boom in economic activity is not followed by a later contraction, as labour supply expands during the whole length of the program. Many of the models predictions are in accordance with the stylized facts on disinflation in chronic-inflation countries, in particular those of the Mexican program of 1988–1992.

Yield Curve Dynamics and Spillovers in Central and Eastern European Countries

This paper applies the models used to study yield curve dynamics and spillovers in the U.S. and other countries to Central and Eastern European countries (CEE countries). Using the Diebold, Rudebusch, and Aruoba (2006) dynamic version of the Nelson-Siegel representation of the yield curve, the paper finds that the two-way relationship between macroeconomic and financial variables in the CEE countries is similar to the one in mature economies. However, inflation shocks have very little persistence in the CEE countries, owing to the strong convergence trends in these countries-which tend to re-anchor expectations faster. Increased convergence in policies and market integration over time are associated with a stronger correlation between the levels of the yield curves, while the curves slopes are more driven by idiosyncratic factors. Shifts in the euro yield curve are transmitted both to interest rates and inflation expectations in the CEE countries-and transmission is stronger after 2004.

Pension Reform and Macroeconomic Stability in Latin America

This paper reviews macroeconomic aspects of pension reforms in Latin America, focusing on financial market stability and fiscal sustainability. Concentration of pension fund portfolios in government bonds remains high, and the lack of new investment alternatives has distorted asset prices. Countries have gradually liberalized investments abroad, but remain wary of the impact on foreign currency markets. The fiscal costs of the transition to funded systems have been higher than expected, and have contributed to high debt levels. The paper highlights the importance of coordinating changes in portfolio limits with debt management policies and measures to develop securities markets.

The Role of Credit Markets in a Transition Economy with Incomplete Public Information

In this paper we explore some of the informational problems that constrain the development of credit markets in transition economies. We characterize investment patterns under uncertainty and high costs of entry, when agents learn about the ultimate value of enterprises through production in a Bayesian way. Inefficiencies due to the lack of public information reduce the average return to capital. Under asymmetric information, credit would go to activities that can provide enough co-finance. Credit markets may fail to develop for a while if there is not enough individual wealth to complement credit. Once they operate, credit markets may magnify distortions in equity markets, such as those due to spontaneous privatization. An argument for the sequencing of capital market liberalization is provided.
