Subsidized Vocational Training: Stepping Stone or Trap? An Evaluation Study for East Germany
Eva Dettmann, Jutta Günther
IWH Discussion Papers,
No. 21,
2009
Abstract
The aim of this paper is to analyze whether the formally equal qualifications acquired during a subsidized vocational education induce equal employment opportunities compared to regular vocational training. Using replacement matching on the basis of a statistical distance function, we are able to control for selection effects resulting from different personal and profession-related characteristics, and thus, to identify an unbiased effect of the public support. Besides the ‘total effect’ of support, it is of special interest if the effect is stronger for subsidized youths in external training compared to persons in workplace-related training. The analysis is based on unique and very detailed data, the Youth Panel of the Halle Centre for Social Research (zsh).
The results show that young people who successfully completed a subsidized vocational education are disadvantaged regarding their employment opportunities even when controlling for personal and profession-related influences on the employment prospects. Besides a quantitative effect, the analysis shows that the graduates of subsidized training work in slightly worse (underqualified) and worse paid jobs than the adolescents in the reference group. The comparison of both types of subsidized vocational training, however, does not confirm the expected stronger effect for youths in external vocational education compared to workplace-related training.

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.

Technology Clubs, R&D and Growth Patterns: Evidence from EU Manufacturing
Claire Economidou, J. W. B. Bos, Michael Koetter
European Economic Review,
No. 1,
2010
Abstract
This paper investigates the forces driving output change in a panel of EU manufacturing industries. A flexible modeling strategy is adopted that accounts for: (i) inefficient use of resources and (ii) differences in the production technology across industries. With our model we are able to identify technical, efficiency, and input growth for endogenously determined technology clubs. Technology club membership is modeled as a function of R&D intensity. This framework allows us to explore the components of output growth in each club, technology spillovers and catch-up issues across industries and countries.

A Panel Data Analysis on China's Intra-Industry Trade in the Capital Goods Sector
Yiping Zhu
IWH Discussion Papers,
No. 18,
2009
Abstract
Diese Studie verwendet die Methode der Hausman-Taylor-2SLS Fehler-Komponenten zur Schätzung der Determinanten von Chinas Intraindustriellem
Handel (IIT) im Investitionsgütersektor mit seinen 26 Partnerländern. Sie disaggregiert IIT in horizontalen IIT (HIIT) und vertikalen IIT (VIIT). Investitionsgüter, Endprodukte und Halbfertigwaren werden separat geschätzt, um die Unterschiede des Handels zu interpretieren. Es zeigt sich, dass die wirtschaftliche Ähnlichkeit mit IIT-Halbfertigwaren signifikant negativ korreliert ist, aber bei IIT-Endprodukten keine Signifikanz besteht. Der Faktor Ausstattung weist keine Signifikanz bei der Bestimmung von IIT-Halbfertigwaren auf, obwohl er mit IIT-Endprodukten signifikant positiv korreliert ist. Wirtschaftsgröße ist sowohl mit IIT-Endprodukten als auch mit IIT-Halbfertigwaren signifikant negativ korreliert. Entfernung wirkt sich auf das Niveau von IIT-Endprodukten aus, hat aber einen geringeren Einfluss auf IIT-Halbfertigwaren. China hat im Bereich Halbfertigwaren relativ wenig intraindustriellen Handel mit ASEAN-Staaten. Da jedoch VIIT einen dominierenden Einfluss auf TIIT ausübt, bestehen keine bedeutenden Unterschiede zwischen den Schätzungsergebnissen von TIIT und VIIT.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
IWH Discussion Papers,
No. 16,
2009
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts
based on a number of forecasting techniques from the literature using a panel of
ten industrialized countries during the period of 1988 to 2007. To capture expected
inflation we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

Low Skill but High Volatility?
Claudia M. Buch
CESifo Working Paper No. 2665,
2009
Abstract
Globalization may impose a double-burden on low-skilled workers. On the one hand, the relative supply of low-skilled labor increases. This suppresses wages of low-skilled workers and/or increases their unemployment rates. On the other hand, low-skilled workers typically face more limited access to financial markets than high-skilled workers. This limits their ability to smooth shocks to income intertemporally and to share risks across borders. Using cross-country, industry-level data for the years 1970 - 2004, we document how the volatility of hours worked and of wages of workers at different skill levels has changed over time. We develop a stylized theoretical model that is consistent with the empirical evidence, and we test the predictions of the model. Our results show that greater financial globalization and development increases the volatility of employment, and this effect is strongest for low-skilled workers. A higher share of low-skilled employment has a dampening impact.

Shadow Budgets, Fiscal Illusion and Municipal Spending: The Case of Germany
Peter Haug
IWH Discussion Papers,
No. 9,
2009
Abstract
The paper investigates the existence of fiscal illusion in German municipalities with special focus on the revenues from local public enterprises. These shadow budgets tend to increase the misperception of municipal tax prices and seem to have been neglected in the literature. Therefore, an aggregated expenditure function has been estimated for all German independent cities applying an “integrated budget” approach, which means
that revenues and expenditures of the core budget and the local public enterprises are combined to one single municipal budget. The estimation results suggest that a higher relative share of local public enterprise revenues might increase total per capita spending as well as spending for non-obligatory municipal goods and services. Empirical evidence for other sources of fiscal illusion is mixed but some indications for debt illusion, renter illusion or the flypaper effect could be found.

Is the European Monetary Union an Endogenous Currency Area? The Example of the Labor Markets
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
No. 7,
2009
Abstract
Our study tries to find out whether wage dynamics between Euro member countries became more synchronized through the adoption of the common currency. We calculate bivarate correlation coefficients of wage and wage cost dynamics and run a model of endogenously induced changes of coefficients, which are explained by other variables being also endogenous: trade intensity, sectoral specialization, financial integration. We used a panel data structure to allow for cross-section weights for country-pair observations. We use instrumental variable regressions in order to disentangle exogenous from endogenous influences. We applied these techniques to real and nominal wage dynamics and to dynamics of unit labor costs. We found evidence for persistent asymmetries in nominal wage formation despite a single currency and monetary policy, responsible for diverging unit labor costs and for emerging trade imbalances among the EMU member countries.
