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
Ulrich Blum
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.

Abstract
The monthly calculation of the Consumer Price Index is based on a sample survey in different municipalities. This study intends to evaluate and improve the representativity of the municipalities within the sample in Saxony-Anhalt with respect to their number and type applying multivariate analysis. The analysis uses variables representing both demand and supply conditions in the municipalities that determine market outcomes. It also considers the importance of a municipality for the neighbouring area.

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.

Wie effektiv sind Technologie- und Gründerzentren in den Neuen Bundesländern?
Michael Schwartz
List Forum für Wirtschafts- und Finanzpolitik,
2008
Abstract
In Eastern Germany, since the beginning of the 1990s technology centers and business incubators are established by cities and municipalities to provide a favorable business environment for young and newly founded innovative firms. Right from the beginning, the effectiveness of these support facilities has been the subject of intense academic and policy discussions, but empirical evidence on the actual effectiveness of these centers is limited so far. Taking into account that the choice of the appropriate criteria for evaluations of the effectiveness of technology centers and business incubators is far from clear cut, this article focuses on three core indicators that are generally accepted as measures for effectiveness (incubation time, share of newly founded firms in the tenant portfolio and technological level of the supported firms), and analyses for five business incubators in East Germany whether they can be characterized as being effective policy instruments. A positive assessment of the five incubators’ effectiveness can be made with regard to average incubation time of tenant companies, as well as insofar the share of newly founded firms on all supported companies is concerned. However, deficiencies are found regarding the technological level of the incubator firms.

Real Options of Private House Owners in the East German Housing Market – How Demolition Subsidies Affect Investment Prospects for Private House Owners
Dominik Weiß
Wirtschaft im Wandel,
No. 6,
2008
Abstract
The subsidies of the German urban renewal program “Stadtumbau Ost” are claimed mainly by communal and cooperative housing companies. The instruments do not fit very well for private proprietors that hold a great part of the older housing stock in central locations, for example in Wilhelminian style districts. Interim evaluation reports concerning the implementation of the “Stadtumbau” program show good results for big housing blocks, but constantly high vacancy rates in the inner city quarters. It becomes obvious that the political targets have not been achieved completely so far and that market forces limit the extensive restoration of historic buildings.
The opportunities, economic incentives and the decisions of landlords and house owners will be analyzed with a real option approach. A detailed view considers the different available forms of subsidies, examining its power to affect real estate values and to initiate politically desired urban transformations. It can be shown that the current forms of subsidies fail to promote investment of private house owners because of rising value expectations. Downgrading the building zones to lower density might reduce unrealistic expectations that were identified as a hurdle to invest. As a consequence from this consideration, municipalities should implement alternative urban development concepts and adjust the subsidy policy.

Forecasting the CO2 certificate price risk
Henry Dannenberg, Wilfried Ehrenfeld
IWH Discussion Papers,
No. 5,
2008
Abstract
Modeling the price risk of CO2 certificates is one important aspect of integral corporate risk management related to emissions trading. The paper presents a risk model which may be the basis for evaluating the risk of emission certificate prices. We assume that the certificate price is determined by the expected marginal CO2 abatement costs prevailing at the current trade period and stochastically fluctuates around the respective level as returned from the mean reversion process. Due to uncertainties about future environmental states we suppose that within one trade period, erratic changes in the expected marginal abatement costs may occur leading to shifts in the price level. The aim of the work is to model the erratic changes of the expected reversion level and to estimate the parameters of the mean reversion process.
