No. 16,

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.

Returning to East Germany: Labour Market Success Reduces Re-migration Potential

Wirtschaft im Wandel,
No. 9,
2009
Abstract
In the public debate, the brain drain from East Germany is supposed to be the most critical trend regarding the development and catching-up of the New Länder. Therefore, potential for in- and re-migration has attracted much attention at least in the political context. Our contribution analyses the re-migration potential on the basis of data from a DFG research project focusing on the re-migration intentions of people formerly emigrated from Saxony-Anhalt. The analysis concentrates on two aspects: firstly on the effect of job market success after emigration; secondly on the impact of social ties in the origin and the host region on the re-migration potential. The econometric results confirm the expected effects: On the one hand, an individual’s job market success in the target region reduces the re-migration potential. Likewise, the re-migration potential increases for people whose former expectations were disappointed. On the other hand, the analysis shows the relevance of social ties to the region of origin for re-migration potential.

Demographic Change and Labour Markets: Why are Older Employees less Mobile?
Lutz Schneider
Wirtschaft im Wandel,
No. 10,
2008
Abstract
Since older workers are less disposed to change jobs workforce ageing will affect labour mobility in Germany. On the basis of the IAB-Employment Sample (IABS) the contribution analyzes the effect of age on job and occupational mobility. The study focuses on the question whether older workers are less mobile due to the optimal matching quality of their current job which cannot be improved by job switches or whether other factors have to be considered for explaining the age related mobility decline.
Econometric results firstly confirm the significance of expected wage growth for mobility decision across all age groups. Secondly, older workers seem to benefit from wage increase due to a job change less frequently than younger workers. However, this factor explains only a part of the mobility lag. Even after controlling for the wage effect younger workers change jobs more often than older ones.
For this reason the opinion that ageing will impede the labour market adjustments cannot be disabled. If older workers only slightly react on wage signals and do not respond to attractive offers growing firms might face problems to recruit appropriate staff – a trend which could have negative consequences for technological and sectoral changes of the entire economy.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West
Johannes Stephan, Wolfgang Steffen
Eastern European Economics,
No. 6,
2008
Abstract
This paper assess determinants of productivity gaps between firms in the European transition countries and regions and firms in West Germany. The analysis is conducted at the firm level by use of a unique database constructed by field work. The determinants tested in a simple econometric regression model are focussed upon the issue of human capital and modern market-oriented management. The results are novel in as much as a solution was established for the puzzling results in related research with respect to a comparison of formal qualification between East and West. Furthermore, the analysis was able to establish that the kind of human capital and expertise mostly needed in the post-socialist firms are related to the particular requirements of a competitive market-based economic environment. Finally, the analysis also finds empirical support for the role of capital deepening in productivity catch-up, as well as the case that the gaps in labour productivity are most importantly rooted in a more labour-intense production, which does not give rise to a competitive disadvantage.

A Simple Representation of the Bera-Jarque-Lee Test for Probit Models
Joachim Wilde
IWH Discussion Papers,
No. 13,
2007
Abstract
The inference in probit models relies on the assumption of normality. However, tests of this assumption are not implemented in standard econometric software. Therefore, the paper presents a simple representation of the Bera-Jarque-Lee test, that does not require any matrix algebra. Furthermore, the representation is used to compare the Bera-Jarque- Lee test with the RESET-type test proposed by Papke and Wooldridge (1996).

Determinants of Female Migration – The Case of German NUTS 3 Regions
Alexander Kubis, Lutz Schneider
IWH Discussion Papers,
No. 12,
2007
Abstract
Our study examines the regional patterns and determinants of migration flows of young women. At the NUTS-3 regional level, i.e. the district level (Kreise), the German internal migration flows of the year 2005 are explored. From descriptive statistics it can be seen that peripheral regions in East Germany face the strongest migration deficit with respect to young women, whereas agglomerations in West Germany but also in the East benefit from an intense migration surplus within this group. An econometric analysis of determinants of regional migration flows gives evidence of the importance of labour market, family-related and educational migration motives. Generally speaking, young women tend to choose regions with good income and job opportunities, in addition they seem to be attracted by regions enabling an appropriate balance between family and career. Furthermore the existence of excellent educational facilities is a significant influence for young women’s migration. This educationally motivated type of migration generates a long lasting effect on the regional migration balance, especially when the educational opportunities in the destination region are associated with adequate career perspectives for high qualified female graduates. In view of considerable losses due to migration, the study shows various options for action. An important course of action is to incorporate policy measures improving regional employment and income opportunities. Secondly, extending vocational and academic offers addressed to women seems to be a suitable way to stimulate women’s immigration. Moreover, enhancing the social infrastructure, which contributes to a satisfactory work life balance, might attract young women or at least reduce the number of them leaving a region.

The Role of Credit Ratings in Banking Regulations. Credit Ratings Are Insufficiently Anticipating the Risk for Currency Crises.
Tobias Knedlik, Johannes Ströbel

No. 10,
2007
Abstract
This contribution analyses whether the behaviour of rating agencies has changed since their failure to predict the Asian crisis. The paper finds no robust econometric evidence that rating agencies have started to take micro-mismatches into account when assigning sovereign ratings. Thus, given the current approach of credit rating agencies, we have reservations concerning the effectiveness of Basel II to prevent the transmission from currency crises to banking crises for potential future crises.

„Where Have All the Young Girls Gone …?” Regional Analysis of Young Women’s Migration Behavior
Alexander Kubis, Lutz Schneider
Wirtschaft im Wandel,
No. 8,
2007
Abstract
The study examines the patterns and determinants of migration flows of young women at the age between 18 and 30 years. At the NUTS-3 regional level, i.e. the district level (Kreise), the German internal migration flows of the year 2005 are explored. From descriptive statistics it can be seen that peripheral regions in East Germany face the strongest migration deficit with respect to young women, whereas agglomerations in West Germany but also in the East benefit from an intense migration surplus within this group. The econometric analysis of determinants of regional migration flows emphasizes the importance of economic, family-related and educational migration motives. Generally speaking, young women tend to choose regions with good income and job opportunities. In addition, they seem to be attracted by regions enabling an appropriate balance between family and career. Furthermore, the existence of excellent educational facilities is a significant pull factor regarding young female migration. This educationally motivated type of migration generates an enduring effect on the regional balance of migration, which is especially true if the educational opportunities in the target region are associated with adequate career perspectives for highly qualified female graduates. In terms of recommendations for action, the study underlines the importance of policy measures improving the regional job and income opportunities. Secondly, the upgrading of fields of study mainly chosen by women seems to be a suitable way to stimulate female immigration. Moreover, the enhancement of the social infrastructure, which promotes a satisfactory work life balance, might attract young women or at least reduce the number of them leaving the region.

The East German Cement Cartel: Cartel Efficiency and Policy after Economic Transformation
Ulrich Blum
Eastern Economic Review,
2007
Abstract
In 2003 the German Antitrust Commission (GAC) proved the existence of a cartel in the German cement industry. The German cement producers involved in the case were fined € 661 million for having established quotas to extract additional rents. One of the main centers of this cartel was East Germany, where the East German Cement Combine with its giant facilities had been sold, in the early 1990s, to four large producers by Treuhand in the process of privatizing the economy. Only in respect to in this market did all defendants concede having had a part in forming a cartel.
In this paper, we challenge the argument of excess revenue that the GAC puts forward for the East German market. We argue that legal evidence does not necessarily translate into economic evidence. We show that demand for cement is realized in geographical and, to a more limited extent, in product space. Thus, in the absence of cartels we would expect monopolistic competition to prevail. We argue that any transition in the market regime, from the cartel to the post cartel period, must be traceable in the individual firm’s demand function which differs from the clients’ demand function because of costs for spatial and product differentiation. Within the framework of an econometric model, we cannot identify any structural changes in demand. Most likely, imports from Poland and the Czech Republic were dumped into the East German market and some medium sized producers were responsible for the cartel never working.
Finally the paper shows how difficult it is to generate competition in certain industries even under the umbrella of a well-established market economy, i.e. that of West Germany, and that the openness of the economy, i.e. trans-border shipments, are decisive.
