Abstract:
During Apartheid, there was little need for redistributional policies or to borrow for public works since the vast majority of the population was underserved. With the arrival of a representative democracy in 1994, however, South Africa faced a unique problem-- providing new and improved public services for the majority of its citizens while at the same time ensuring that filling this void would not undermine macroeconomic stability. Over the past fifteen years, policy makers have achieved macrostability, but progress on social needs has been below expectations and South Africa continues to lag behind its peers. This paper reviews the progress made so far and examines the challenges ahead for the upcoming administration. Our analysis suggest an increase in skill formation as a possible solution to the policy dilemma of fullfilling the outsized social demands while maintaining macrostability.

Abstract:
This paper builds a model of two types of Chinese exports, those processed and assembled laregely from imported inputs ("processed" exports) and "non- processed" exports. Based on this model, the sensitivity of Chinese exports to exchange rate changes is empirically examined. Unlike previous work, the estimation period includes the net real appreciation of the renminbi that has occurredoverthepastthreeyears. Theresultsshowthatgreaterexchangerate appreciation dampens export growth, both for non-processed and processed ex- ports, with the estimated cumulative price elasticity being substantially greater thanunity. WhenthesourceoftheincreaseintheChineserealexchangerateis appreciations against the currencies of other emerging Asian trading partners, the e§ect on processing exports is positive but insignÖcant, while the e§ect on non-processing exports is signiÖcantly negative. By contrast, when the source of the increase in the Chinese real exchange rate is appreciation against Chinaís advanced-economy trading partners, the e§ects on both types of exports are negative. These results are consistent with the predictions of the theoretical model. Counterfactualsimulationsbasedontheestimatedmodelstronglysug- gest that if the trade-weighted real renminbi had appreciated at an annual rate of 10 percent per quarter since mid-2005, Chinese real exports would have been roughly 30 percent lower today. Thus greater exchange rate áexibility could contribute to lowering Chinaís huge trade surplus through restraining growth of exports.

43. Labor Market Search in Emerging Economies

Abstract:
This paper shows that labor markets of emerging economies are characterized by large fluctuations in wages while employment fluctuations are subdued. We find that a real business cycle model of a small open economy that embeds a Mortensen-Pissarides type of search-matching frictions can account for these aforementioned regularities. Moreover, the joint interaction of countercyclical interest rates and search-matching frictions can go a long way in accounting for higher consumption variability relative to output and countercyclical current account observed in emerging markets. Extending this baseline model to incorporate procyclical variations in the technical efficiency at which matches are generated, the model can match the unemployment variability observed in the data.

44. International Competition and Inflation: A New Keynesian Perspective

Author:
Luca Guerrieri, Christopher Gust, and David López-Salido

Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
We develop and estimate an open economy New Keynesian Phillips curve (NKPC) in which variable demand elasticities give rise to changes in desired markups in response to changes in competitive pressure from abroad. A parametric restriction on our specification yields the standard NKPC, in which the elasticity is constant, and there is no role for foreign competition to influence domestic inflation. By comparing the unrestricted and restricted specifications, we provide evidence that foreign competition plays an important role in accounting for the behavior of inflation in the traded goods sector. Our estimates suggest that foreign competition has lowered domestic goods inflation about 1 percentage point over the 2000-2006 period. Our results also provide evidence against demand curves with a constant elasticity in the context of models of monopolistic competition.

45. Measuring U.S. International Relative Prices: A WARP View of the World

Author:
Charles P. Thomas, Jaime Marquez, and Sean Fahle

Abstract:
In this paper we construct a new measure of U.S. prices relative to those of its trading partners and use it to reexamine the behavior of U.S. net exports. Our measure differs from existing measures of the dollar's real effective exchange rate (REER) in that it explicitly incorporates both the difference in price levels between the United States and developing economies and the growing importance of these developing economies in world trade. Unlike existing REERs, our measure shows that relative U.S. prices have increased significantly over the past 15 years. In terms of simple correlations, the relationship between our measure of relative prices and U.S. net exports is much more coherent than that between existing REERs and net exports. To explore this relationship further, we use our measure to construct an index of foreign prices relevant for U.S. export volumes and reexamine several export equations. We find that export equations with the new index dominate those with previous measures in terms of in-sample fit, outof- sample fit, and parameter constancy. In addition, we find that with the new index of foreign prices the estimated elasticity of U.S. exports with respect to foreign income is a good bit higher than the unitary elasticity found in previous studies using other price measures. This has implications for U.S. current account adjustment.

46. Political Disagreement, Lack of Commitment and the Level of Debt

Author:

Board of Governors of the Federal Reserve System
Abstract:
We analyze how public debt evolves when successive policymakers have different policy goals and cannot make credible commitments about their future policies. We consider several cases to be able to disentangle and quantify the respective effects of imperfect commitment and political disagreement. Absent political turnover, imperfect commitment drives the long-run level of debt to zero. With political disagreement, debt is a sizeable fraction of GDP and increasing in the degree of polarization among parties, no matter the degree of commitment. The frequency of political turnover does not produce quantitatively relevant effects. These results are consistent with much of the existing empirical evidence. Finally, we find that in the presence of political disagreement the welfare gains of building commitment are lower.

47. Optimal Fiscal and Monetary Policy in Customer Markets

Author:
David M. Arseneau and Sanjay K. Chugh

Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
A growing body of evidence suggests that ongoing relationships between consumers and firms may be important for understanding price dynamics. We investigate whether the existence of such customer relationships has important consequences for the conduct of both long-run and short-run policy. Our central result is that when consumers and firms are engaged in long-term relationships, the optimal rate of price inflation volatility is very low even though all prices are completely flexible. This finding is in contrast to those obtained in first-generation Ramsey models of optimal fiscal and monetary policy, which are based on Walrasian markets. Echoing the basic intuition of models based on sticky prices, unanticipated inflation in our environment causes a type of relative price distortion across markets. Such distortions stem from fundamental trading frictions that give rise to long-lived customer relationships and makes pursuing inflation stability optimal.

48. On the Application of Automatic Differentiation to the Likelihood Function for Dynamic General Equilibrium Models

Abstract:
A key application of automatic differentiation (AD) is to facilitate numerical optimization problems. Such problems are at the core of many estimation techniques, including maximum likelihood. As one of the first applications of AD in the field of economics, we used Tapenade to construct derivatives for the likelihood function of any linear or linearized general equilibrium model solved under the assumption of rational expectations. We view our main contribution as providing an important check on finite-difference (FD) numerical derivatives. We also construct Monte Carlo experiments to compare maximum-likelihood estimates obtained with and without the aid of automatic derivatives. We find that the convergence rate of our optimization algorithm can increase substantially when we use AD derivatives.

Abstract:
Were the U.S. to persistently earn substantially more on its foreign investments ("U.S. claims") than foreigners earn on their U.S. investments ("U.S. liabilities"), the likelihood that the current environment of sizeable global imbalances will evolve in a benign manner increases. However, using a monthly dataset on the foreign equity and bond portfolios of U.S. investors and the U.S. equity and bond portfolios of foreign investors, we find that the returns differential for portfolio securities is near zero, far smaller than previously reported. Examining all U.S. claims and liabilities (portfolio securities as well as direct investment and banking), we find that previous estimates of large differentials are biased upward. The bias owes to computing implied returns from an internally inconsistent dataset of revised data; original data produce a much smaller differential. We also attempt to reconcile our finding of a near zero returns differential with observed patterns of cumulated current account deficits, the net international investment position, and the net income balance. Overall, we find no evidence that the U.S. can count on earning substantially more on its claims than it pays on its liabilities.

50. Cross-border Bank Acquisitions: Is there a Performance Effect?

Author:
Ricardo Correa
Publication Date:

Content Type:
Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
This paper uses a unique database that includes deal and bank balance sheet information for 220 cross-border acquisitions between 1994 and 2003 to analyze the characteristics and performance effects of international takeovers on target banks. A discrete choice estimation shows that banks are more likely to get acquired in a cross-border deal if they are large, bad performers, in a small country, and when the banking sector is concentrated. Post-acquisition performance for target banks does not improve in the first two years relative to domestically-owned financial institutions. This result is explained by a decrease in the banks' net interest margin in developed countries and an increase in overhead costs in emerging economies.
