Optimum Currency Areas in Emerging Market Regions: Evidence Based on the Symmetry of Economic Shocks
Stefan Eichler, Alexander Karmann
Open Economies Review,
No. 5,
2011
Abstract
This paper examines which emerging market regions form optimum currency areas (OCAs) by assessing the symmetry of macroeconomic shocks. We extend the output-prices-VAR framework by adding net exports and the real effective exchange rate as endogenous variables. Based on theoretical considerations, we derive which shocks affect these variables in the long run: shocks to labor productivity, foreign trade, labor supply, and money supply. The considered economies of Central and Eastern Europe, the Commonwealth of Independent States, East and Southeast Asia, and South Asia, exhibit large enough shock symmetry to form a currency union; the economies of Africa, Latin America, and the Middle East do not.

Can Korea Learn from German Unification?
Ulrich Blum
IWH Discussion Papers,
No. 3,
2011
Abstract
We first analyze pre-unification similarities and differences between the two Germanys and the two Koreas in terms of demographic, social, political and economic status. An important issue is the degree of international openness. “Stone-age” type communism of North Korea and the seclusion of the population prevented inner-Korean contacts and contacts with rest of the world. This may create enormous adjustment costs if institutions, especially informal institutions, change. We go on by showing how transition and integration interact in a potential unification process based on the World Bank Revised Minimum Standard Model (RMSM) and on the Salter-Swan-Meade model. In doing so, we relate the macro and external impacts on an open economy to its macro-sectoral structural dynamics. The findings suggest that it is of utmost importance to relate microeconomic policies to the macroeconomic ties and side conditions for both parts of the country. Evidence from Germany suggests that the biggest general error in unification was neglecting these limits, especially limitations to policy instruments. Econometric analysis supports these findings. In the empirical part, we consider unification as an “investment” and track down the (by-and-large immediate to medium-term) costs and the (by-and-large long-term) benefits of retooling a retarded communist economy. We conclude that, from a South-Korean
perspective, the Korean unification will become relatively much more expensive than the German unification and, thus, not only economic, but to a much larger degree political considerations must include the tying of neighboring countries into the convergence process. We finally provide, 62 years after Germany’s division and 20 years after unification, an outlook on the strength of economic inertia in order to show that it may take much more than a generation to compensate the damage inflicted by the communist system.

Möglichkeiten für Vollbeschäftigungspolitik im Rahmen des Europäischen Makroökonomischen Dialogs
Toralf Pusch, A. Heise
K. Busch (Hrsg.), Wirtschaftliche und Soziale Integration in der Europäischen Union,
2010
Abstract
A decade after its introduction the European Monetary Union is no more undisputed. While a successful record regarding price stability cannot be doubted, the EMU still suffers from high unemployment – not only related to the Financial Crisis. In this contribution we want to cast light on the question how this might be related to a dismal mix of wage policy and monetary policy. Taking a consideration of the European Macroeconomic Dialogue as a starting point, we develop a game theoretic model which can explain different macroeconomic alternatives. As a result we present a reputation equilibrium which would make full employment and price stability compatible and does not rest on overriding the actors’ independence.

Arbeitskosteneffekte des Vorleistungsbezugs der Industrie an Dienstleistungen in Deutschland im Vergleich mit Frankreich und den Niederlanden – Eine Untersuchung mit der Input-Output-Methode. Gutachten im Auftrag des Instituts für Makroökonomie und Konjunkturforschung (IMK)
Udo Ludwig, Hans-Ulrich Brautzsch

Abstract
As part of the outsourcing, industrial enterprises receive services in the production of their products which they used to provide on their own. As a result of the wage differentials between industry and service sector there is a shift in the burden labour costs have on industrial products. The study addresses the question of how significant this effect is. For this purpose the open static input-output model is used to analyse the degree of integration of the industry with its suppliers, the employment intensity of production and the labour cost differentials between the areas of production in Germany and in comparison with France and the Netherlands. The result of the labour cost analysis of industrial production shows - from a macroeconomic point of view - that the industry products have a smaller burden due to labour costs in Germany, France and the Netherlands, than the sectoral levels in the industry indicate. The difference in Germany is quantitative particularly strong pronounced. This saving in wage costs has increased somewhat after 2000. Crucial is that this discharge effect is achieved on the immediate wholesale inputs, that means in the first integration stage of industrial production.

Testing for Structural Breaks at Unknown Time: A Steeplechase
Makram El-Shagi, Sebastian Giesen
Abstract
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown, Durbin, and Evans (1975) and Zeileis (2004), Nyblom (1989) and Hansen (1992), and Andrews, Lee, and Ploberger (1996). Power and size properties are derived using Monte Carlo simulations. Results emphasize that mostly the CUSUM type tests are affected by the presence of heteroscedasticity, whereas the individual parameter Nyblom test and AvgLM test are proved to be highly robust. However, each test is significantly affected by leptokurtosis. Contrarily to other tests, where skewness is far more problematic than kurtosis, it has no additional effect for any of the endogenous break tests we analyze. Concerning overall robustness the Nyblom test performs best, while being almost on par to more recently developed tests in terms of power.

Transmission of Nominal Exchange Rate Changes to Export Prices and Trade Flows and Implications for Exchange Rate Policy
Mathias Hoffmann, Oliver Holtemöller
Scandinavian Journal of Economics,
2010
Abstract
We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these two parameters for which flexible and fixed exchange rates are superior with respect to welfare as measured by a representative household's utility level. We estimate the two parameters for six non-EMU European countries (Czech Republic, Hungary, Poland, Slovakia, Sweden, and the UK) using a heterogeneous dynamic panel approach.

Macroeconomic Shocks and Banks' Foreign Assets
Claudia M. Buch, K. Carstensen, A. Schertler
Journal of Money, Credit and Banking,
No. 1,
2010
Abstract
Recent developments in international financial markets have highlighted the role of banks in the transmission of shocks across borders. We employ dynamic panel methods for a sample of OECD countries to analyze whether banks' foreign assets react to macroeconomic shocks at home and abroad. We find that banks reduce their foreign assets in response to a relative increase in domestic interest rates, and they increase their foreign assets when the growth rate of world energy prices rises. The responses are characterized by a temporal overshooting and a dynamic adjustment process that extends over several quarters.

A Simple Macro Model of Original Sin based on Optimal Price Setting under Incomplete Information
Axel Lindner
International Economics and Economic Policy,
2009
Abstract
This paper analyses the consequences of “original sin“ (the fact that the currency of an emerging market economy usually cannot be used to borrow abroad) for macroeconomic stability. The approach is based on third-generation models of currency crises, but differs from alternative versions by explicitly modeling the price setting behavior of firms if prices are sticky and there is incomplete information about the future exchange rate. It is shown that a small depreciation is beneficial, but a large one is detrimental.
