Openness and Income Disparities: Does Trade Explain The 'Mezzogiorno' Effect?
Claudia M. Buch, P. Monti
Review of World Economics,
No. 4,
2010
Abstract
We use Italian regional data to answer the question whether trade affects within-country income differentials. In Italy, the more affluent Northern regions trade more with the rest of the world than the poorer ones in the Southern “Mezzogiorno” regions. Prima facie, there is a positive correlation between external trade and per capita income. Studying this relationship empirically requires taking into account the endogenous component of trade. We argue that panel cointegration models can complement instrumental variables techniques to account for the endogeneity of trade in a panel context. Both methods show a positive link between trade openness and the level of income per capita.

Germany’s Production of Export Goods: Human Capital Content Slightly Exceeds that of Imports
Hans-Ulrich Brautzsch, Udo Ludwig
Wirtschaft im Wandel,
No. 11,
2009
Abstract
In the decade before the present, world financial crisis exports out of Germany expanded enormously. This was caused by the growing world demand as well as the internationalization of the national production processes and favoured by the improving price competitiveness. At the same time, against the background of the tertiarisation of the economy, the qualification of employees has increased considerably. In our study, we investigate the changes of labour quality in the production of export goods using the standard open input-output model. Hereby, labour input is measured in terms of different formal qualification levels of the employees. The results are compared with the labour input for imported goods. We find out that the input of high qualified labour per unit of produced export goods exceeds only marginally the comparable input value of the imports. It should be mentioned that the comparison is strongly influenced by the assumption of identical production functions for both Germany and its trading partners.

East German Exports: Remarkable Catch-up, but Still Lagging Behind
Götz Zeddies
Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
German reunification entailed severe adjustment processes in East German export industries. With political and economic transition in Eastern Europe, at that time the main export market for East German producers, export demand initially collapsed in the early 1990s. Additionally, the introduction of the Deutschmark in Eastern Germany amounted to a massive revaluation, and international competitiveness of East German producers deteriorated. However, manufacturers in the New Federal States opened up new markets, especially in Western Europe and the Americas. As a consequence, after the downturn of construction activity and investment in the mid-1990s, international trade became the driving force of GDP-growth in Eastern Germany. Although since then, goods exports of the New Federal States grew twice as much as those of Western Germany, export ratio (goods exports as a percentage of GDP) only amounts to 22 per cent in Eastern Germany, compared to 42 per cent in the western part of the country. Even in comparison to Eastern European countries in transition, openness to trade of the New Federal States is still comparatively low. As an empirical analysis shows, this must be largely traced back to smaller firm sizes in the New Federal States as well as to the lower importance of manufacturing industries, which are traditionally more export-oriented. Moreover, East German manufacturers largely specialized on intermediate inputs, which are supplied to final assembly lines in Western Germany, but are not recorded as exports. Thereby, East German export performance is considerably underestimated.

Openness and Growth: The Long Shadow of the Berlin Wall
Claudia M. Buch, Farid Toubal
Journal of Macroeconomics,
No. 3,
2009
Abstract
The question whether international openness causes higher domestic growth has been subject to intense discussions in the empirical growth literature. This paper addresses the issue in the context of the fall of the Berlin Wall in 1989. We analyze whether the slow convergence in per capita incomes between East and West Germany and the lower international openness of East Germany are linked. We address the endogeneity of openness by adapting the methodology proposed by Frankel and Romer (1999) to a panel framework. We instrument openness with time-invariant exogenous geographic variables and time-varying exogenous policy variables. We also distinguish the impact of different channels of integration. Our paper has three main findings. First, geographic variables have a significant impact on regional openness. Second, controlling for geography, East German states are less integrated into international markets along all dimensions of integration considered. Third, the degree of openness for trade has a positive impact on regional income per capita.

Currency Appreciation and Exports: Empirical Evidence for Germany
Götz Zeddies
Wirtschaft im Wandel,
No. 6,
2009
Abstract
In the first decade after its introduction, the Euro didn’t just hold up well, but compared to important currencies even appreciated considerably. Of course, exchange rate risks were noticeably lowered by introducing the single currency, since the bulk of EMU Member States’ exports are conducted within the currency union. Nevertheless, a strong Euro is unfavourable especially for open economies like Germany.
The article investigates the effects of exchange rate movements on German exports over time. The analyses reveal a downward impact of nominal effective exchange rates, not only for total, but also for exports to countries outside the currency union. Although an increasing pass-through of exchange rate changes to export prices is apparently at hand, further reasons for the dwindling effect of nominal exchange rates on exports are likely to exist.
In this context, it is shown that exports are less sensitive not only with respect to nominal, but also with respect to real effective exchange rate changes, suggesting a declining price elasticity of demand. Instead, exports are increasingly determined by economic activity in trading partner countries. In consequence of its geographic proximity, Germany did particularly benefit from the economic upswing in Eastern Europe, overlaying the appreciation of the Euro. Additionally, the latter could hardly impair German export industries due to their specialization on capital and high-quality consumer goods less vulnerable to exchange rate fluctuations.

Does Export Openness Increase Firm-level Output Volatility?
Claudia M. Buch, Jörg Döpke, H. Strotmann
World Economy,
No. 4,
2009
Abstract
There is a widespread concern that increased trade may lead to increased instability and thus risk at the firm level. Greater export openness can indeed affect firm-level volatility by changing the exposure and the reaction of firms to macroeconomic developments. The net effect is ambiguous from a theoretical point of view. This paper provides firm-level evidence on the link between openness and volatility. Using comprehensive data on more than 21,000 German manufacturing firms for the period 1980–2001, we analyse the evolution of firm-level output volatility and the link between volatility and export openness. Our paper has three main findings. First, firm-level output volatility is significantly higher than the level of aggregate volatility, but it displays similar patterns. Second, increased export openness lowers firm-level output volatility. This effect is primarily driven by variations along the extensive margin, i.e. by the distinction between exporters and non-exporters. Variations along the intensive margin, i.e. the volume of exports, tend to have a dampening impact on volatility as well. Third, small firms are more volatile than large firms.

Trade's Impact on the Labor Share: Evidence from German and Italian Regions
Claudia M. Buch
IAW Discussion Paper No. 46,
2008
Abstract
Has the labor share declined? And what is the impact of international trade? These
questions are not only relevant in an international context they also matter for
understanding the regional distribution of incomes in a given country. In this
paper, we study two regions with trade exposures that differ from the rest of the
country, and which display distinct changes in the labor share. East German and
Southern Italian regions have a degree of international openness which is below
the countries’ averages. At the same time, there has been a more pronounced
decline in the labor share in East Germany than in West Germany. In Southern
Italy, the labor share has increased in recent years. We show that increased trade
openness is not the main culprit behind changing labor shares.

The Great Risk Shift? Income Volatility in an International Perspective
Claudia M. Buch
CESifo Working Paper No. 2465,
2008
Abstract
Weakening bargaining power of unions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This paper documents and explains changes in income volatility. Using a theoretical framework which builds distribution risk into a real business cycle model, hypotheses on the determinants of the relative volatility of capital and labor are derived. The model is tested using industry-level data. The data cover 11 industrialized countries, 22 manufacturing and services industries, and a maximum of 35 years. The paper has four main findings. First, the unconditional volatility of labor and capital incomes has declined, reflecting the decline in macroeconomic volatility. Second, the idiosyncratic component of income volatility has hardly changed over time. Third, crosssectional heterogeneity in the evolution of relative income volatilities is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile in relative terms. Fourth, income volatility is related to variables measuring the bargaining power of workers. Trade openness has no significant impact.

Regional origins of employment volatility: evidence from German states
Claudia M. Buch
CES IFO Working Paper No. 2296,
2008
Abstract
Greater openness for trade can have positive welfare effects in terms of higher growth. But increased openness may also increase uncertainty through a higher volatility of employment. We use regional data from Germany to test whether openness for trade has an impact on volatility. We find a downward trend in the unconditional volatility of employment, paralleling patterns for output volatility. The conditional volatility of employment, measuring idiosyncratic developments across states, in contrast, has remained fairly unchanged. In contrast to evidence for the US, we do not find a significant link between employment volatility and trade openness.

Revenue Implications of Trade Liberalization
L. Ebrill, Reint E. Gropp, J. Stotsky
IMF Occasional Papers, No. 180,
No. 180,
1999
Abstract
In recent decades many countries have dismantled trade barriers and opened their economies to international competition. Trade liberalization is seen to promote economic efficiency, international competitiveness, and an expansion of trade, perhaps especially in imperfectly competitive markets. Yet despite this progress in trade liberalization, as evidenced by the conclusion of the Uruguay Round in 1994 and the establishment of the World Trade Organization (WTO) in 1995, trade barriers are still widespread. Some economies and some sectors (e.g., agriculture in many industrial countries) remain relatively insulated from the global economy by a variety of nontariff and tariff barriers, even as import substitution continues to lose ground as a strategy for economic development.
