Abstract
In the light of favourable business conditions during the previous years, business organizations have repeatedly cautioned about a skilled labour shortage that could constrain future development of enterprises. While shortages may be typical of phases of economic expansion, the skilled labour shortage might turn into a permanent phenomenon if one takes into account the shrinking of the working-age population. The demographic transition occurs at an especially rapid pace in Eastern Germany. At the same time, this region still exhibits high rates of chronic unemployment, which renders the possibility of a skilled labour shortage questionable.
We focus on the federal state of Thuringia and investigate two questions. Firstly, we evaluate to what extent occupation-specific bottlenecks exist both in Germany and in Thuringia, using a set of criteria based on official labour market statistics. We find evidence of high utilization of labour supply in technical and metalworking professions in Germany. In the majority of these occupations, the same is true for Thuringia. Hence, a high level of unemployment and skilled labour shortage may coexist, at least in a transition phase. Secondly, we investigate whether companies in Thuringia already expect problems when searching for skilled personnel in the near future. For this purpose, the IWH has conducted a survey among approximately 1 000 companies. It turns out that 61% of the interviewed companies anticipate such problems, with statistically significant differences with respect to the companies’ characteristics. In addition, we discuss selected policies that companies plan to implement in the field of human resource management when anticipating problems.

Professor Qualities and Student Achievement
Florian Hoffmann, Philip Oreopoulos
Review of Economics and Statistics,
No. 1,
2009
Abstract
This paper analyzes the importance of teacher quality at the college level. Instructors are matched to objective and subjective characteristics of teacher quality to estimate the impact of rank, salary, and perceived effectiveness on student performance and subject interest. Student and course fixed effects, time of day and week controls, and students' lack of knowledge about first-year instructors help minimize selection biases. Subjective teacher evaluations perform well in measuring instructor influences on students, while objective characteristics such as rank and salary do not. Overall, the importance of college instructor differences is small, but important outliers exist.

A Novel Approach to Incubator Evaluations: The PROMETHEE Outranking Procedures
Michael Schwartz, Maximilian Göthner
IWH Discussion Papers,
No. 1,
2009
Abstract
Considerable public resources are devoted to the establishment and operation of business incubators (BIs), which are seen as catalysts for the promotion of entrepreneurship, innovation activities and regional development. Despite the vast amount of research that has focused on the outcomes or effectiveness of incubator initiatives and how to measure incubator performance, there is still little understanding of how to determine incubators that are more effective than others. Based on data from 410 graduate firms, this paper applies the multi-criteria outranking technique PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) and compares the long-term effectiveness of five technology-oriented BIs in Germany. This is the first time that outranking procedures are used in incubator evaluations. In particular, we investigate whether PROMETHEE is a well-suited methodological approach for the evaluation and comparisons in the specific context of business incubation.

No. 1,
2009
Abstract
This article deals with the macroeconomic effects of different economic stimulus packages. It evaluates several measures including direct tax cuts, a reduction of the contribution payment to social security, an increase in government spending and a temporary cut of the value added tax rate. Further, the measures of the latest economic stimulus packages are assessed and it is found that their effects on production and employment are only of moderate size.

Public Housing and the Fear of Private Equity – Assessing Social Impacts
Dominik Weiß
Wirtschaft im Wandel,
No. 12,
2008
Abstract
This contribution examines the consequences of sales of municipal flats to private investors, which have been criticised strongly for social reasons. An evaluation of the German Socio-Economic Panel Study (SOEP) from 1999 to 2006 reveals no serious consequences of the privatisation of municipal flats on the affected households. It cannot produce empirical evidence to foster arguments for the public criticism of the public housing sales. The essential results from this sample point to moderate rent increases and above-average investment activity after the privatisation. However, the analysis of the household´s sentiment whether the total expense load for the flat is adequate shows that tenants in privatised flats found their flat increasingly expensive. A possible reason for this development might be the lower mobility of the residents of municipal flats.

Economic Effects of the Halle Institute for Economic Research

Wirtschaft im Wandel,
No. 10,
2008
Abstract
The most important approach to assess the scholarly performance of an institute is to evaluate its academic output. Economic research institutes such as the Halle Institute for Economic Research (IWH) furthermore are targeted at providing policy advice to public authorities. This adds an additional criterion, the ability to impact policy discussions in Germany and beyond.
A rarely discussed issue is the effect of an institute on the local economy. The IWH is located in a region of East Germany that is still catching up economically. Transformation problems are still very visible. In such an economic environment, the expenditures of an institute play an important role in stabilizing local demand. The analysis shows, by using input-output-methods, that the most important factor for the local economy is the demand stemming from wages earned by the employees of the institute. Especially the local area, where most of the staff lives, heavily benefits from this effect. Expenditures of about 4.6 million Euros which include the salaries of the staff of about 70 persons generates sufficient demand in the area to guarantee employment for another 35 persons. In addition, as crowding out of activities by additional demand is presently not an issue in East Germany, the taxes generated account for a considerable part of the budget.

Evaluating the German (New Keynesian) Phillips Curve
Rolf Scheufele
IWH Discussion Papers,
No. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.

Evaluating communication strategies for public agencies: transparency, opacity, and secrecy
Axel Lindner
IWH Discussion Papers,
No. 8,
2008
Abstract
This paper analyses in a simple global games framework welfare effects stemming
from different communication strategies of public agencies if strategies of agents are complementary to each other: communication can either be fully transparent, or the agency opaquely publishes only its overall assessment of the economy, or it keeps information completely secret. It is shown that private agents put more weight to their private information in the transparent case than in case of opacity. Thus, in many cases, the appropriate measure against overreliance on public information is giving more details to the public instead of denying access to public information.

Long-term Effects of Business Incubators: What Happens to Incubated Firms after they Have Graduated from the BIs?
Michael Schwartz
Wirtschaft im Wandel,
No. 8,
2008
Abstract
Many cities and municipalities devote considerable public resources to the establishment and operation of business incubators (BIs) to promote the survivability and the positive development of newly founded firms. In the context of incubator evaluations, survival is one of the most important performance indicators, and survival rates of incubated firms are frequently communicated to the public by local authorities to demonstrate the success of those policy initiatives. However, in most cases, these data refers to the initial incubation period. Little is known about survival or exit dynamics of incubated firms after they have graduated from the BIs. On the basis of a comprehensive research project concerned with the development of graduate firms from incubators in Dresden, Halle (Saale), Jena, Neubrandenburg and Rostock, this article not only investigates how many firms survive after leaving the incubator facilities, but also investigates if graduation causes an immediate negative effect on subsequent survivability. The results show that about one third of all graduate firms fail after leaving the incubator. Furthermore, it can be found that graduate firms from the BIs in Halle (Saale) and Neubrandenburg face a relatively high risk of business closure especially in the first years after the completion of the incubation period.
