Institutional transition, social capital mix and local ties – Does Communist legacy explain low labour mobility?

Abstract
This paper empirically analyses the question why East Germans facing weak regional labour markets show rather limited spatial mobility. Using data from the German Socio-Economic Panel, our estimation of a simultaneous three equation ordered probit model shows that informal social capital reduces regional mobility while formal social capital supports it. Furthermore, we find that East Germans acculturated in a communist system are more invested in locally bounded informal social capital than in the mobility supporting formal social capital. Low spatial mobility of East Germans, we conclude, is to an important part attributable to a system specific social capital mix.

Innovation and Skills from a Sectoral Perspective: A Linked Employer-Employee Analysis
Lutz Schneider, Jutta Günther, Bianca Brandenburg
Economics of Innovation and New Technology,
2010
Abstract
Science and engineering skills as well as management and leadership skills are often referred to as sources of innovative activities within companies. Broken down into sectoral innovation patterns, this article examines the role of formal education, actual occupation and work experience in the innovation performance in manufacturing firms within a probit model. It uses unique micro data for Germany (LIAB) that contain information about corporate innovation activities and the qualification of employees in terms of formal education, actual professional status and work experience. We find clear differences in the human capital endowment between sectors according to the Pavitt classification. Sectors with a high share of highly skilled employees engage in above average product innovation (specialized suppliers and science-based industries). However, according to our estimation results, across as well as within these sectors a large share of highly skilled employees does not substantially increase the probability of a firm being innovative.

Margins of international banking: Is there a productivity pecking order in banking, too?
Claudia M. Buch
Bundesbank Discussion Paper 12/2009,
2009
Abstract
Modern trade theory emphasizes firm-level productivity differentials to explain
the cross-border activities of non-financial firms. This study tests whether a
productivity pecking order also determines international banking activities. Using
a novel dataset that contains all German banks’ international activities, we
estimate the ordered probability of a presence abroad (extensive margin) and the
volume of international assets (intensive margin). Methodologically, we enrich the
conventional Heckman selection model to account for the self-selection of banks
into different modes of foreign activities using an ordered probit. Four main
findings emerge. First, similar to results for non-financial firms, a productivity
pecking order drives bank internationalization. Second, only a few non-financial
firms engage in international trade, but many banks hold international assets, and
only a few large banks engage in foreign direct investment. Third, in addition to
productivity, risk factors matter for international banking. Fourth, gravity-type
variables have an important impact on international banking activities.

Forecasting Currency Crises: Which Methods signaled the South African Crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
South African Journal of Economics,
2008
Abstract
In this paper we test the ability of three of the most popular methods to forecast South African currency crises with a special emphasis on their out-of-sample performance. We choose the latest crisis of June 2006 to conduct an out-of-sample experiment. The results show that the signals approach was not able to forecast the out-of-sample crisis correctly; the probit approach was able
to predict the crisis but only with models, that were based on raw data. The Markov-regime- switching approach predicts the out-of-sample crisis well. However, the results are not straightforward. In-sample, the probit models performed remarkably well and were also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. The recommendation is to not restrict the forecasting to only one approach.

A note on GMM-estimation of probit models with endogenous regressors
Joachim Wilde
Statistical Papers,
No. 3,
2008
Abstract
Dagenais (1999) and Lucchetti (2002) have demonstrated that the naive GMM estimator of Grogger (1990) for the probit model with an endogenous regressor is not consistent. This paper completes their discussion by explaining the reason for the inconsistency and presenting a natural solution. Furthermore, the resulting GMM estimator is analyzed in a Monte-Carlo simulation and compared with alternative estimators.

Does Temporary Employment Affect the Work-related Training of Low-skilled Employees?
Eva Reinowski, Jan Sauermann
Zeitschrift für Arbeitsmarktforschung,
No. 4,
2008
Abstract
Using the German Mikrozensus 2004, this paper analyses the effect of temporary contracts on work-related training for low-skilled workers. To take systematic differences between temporary and permanent employees into account, we estimate a bivariate probit model for whether fixed-term employment affects participation in work-related training. We conclude that holding a temporary contract does not have systematic disadvantages in access to further training.

Does temporary employment influence the workrelated training of low-skilled employees?
Eva Reinowski, Jan Sauermann
IWH Discussion Papers,
No. 2,
2008
Abstract
Fixed-term contracts are considerd as one of the most popular instruments of labour market flexibility. Although they provide new labour market options for employer and employees, it is argued that they may lead to decreasing investments in human capital. From the theoretical point of view it is not clear wheter a fixed-term contract is a drawback for the participation in work-related training. The paper deals with the influence of fixed-term contracts on work-related training especially for low-skilled workers. Based on the Micro Census data of 2004, we estimate a bivariate probit model for the probability of fixed-term employment and participating in work-related training. This model enables us to control for selection effects that may arise from unobservable factors. From the estimation results we can conclude that holding a fixed-term contract does not mean a systematical disadvantage for the training probability of low-skilled employees.

Three methods of forecasting currency crises: Which made the run in signaling the South African currency crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
IWH Discussion Papers,
No. 17,
2007
Abstract
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.

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).
