Panel Seasonal Unit Root Test With An Application for Unemployment Data
Christian Dreger, Hans-Eggert Reimers
IWH Discussion Papers,
No. 191,
2004
Abstract
In this paper the seasonal unit root test of Hylleberg et al. (1990) is generalized to cover a heterogenous panel. The procedure follows the work of Im, Pesaran and Shin (2002). Test statistics are proposed and critical values are obtained by simulations. Moreover, the properties of the tests are analyzed for di®erent deterministic and dynamic specications. Evidence is presented that for a small time dimension the power is slow even for increasing cross section dimension. Therefore, it seems necessary to have a higher time dimension than cross section dimension. The new test is applied for unemployment behaviour in
industrialized countries. In some cases seasonal unit roots are detected. However, the null hypotheses of panel seasonal unit roots are rejected. The null hypothesis of a unit root at the zero frequency is not rejected, thereby supporting the presence of hysteresis effects.

Promotion of investment in East Germany - Results of an empirical study of effectiveness
Harald Lehmann, Andreas Stierwald
Wirtschaft im Wandel,
No. 5,
2004
Abstract
In Germany considerable amounts of public funds are being spent on business development programs. In order to do so economic reasoning is needed. In particular the programs for supporting investment lack microeconometric empirical evaluation. To close this gap the special program „Gemeinschaftsaufgabe zur Verbesserung der regionalen Wirtschaftsstruktur“ (GA) is exemplarily analyzed. This program is intended to strengthen the capital stock of the East German economy, so firms of the East German manufacturing industries will be studied. A comparison of the two fundamental methods for microeconometric evaluation shall demonstrate the general problems in analyzing the effectiveness of development programs. The matching estimator provides more stable results then a sample selectivity model. The results suggest that the GA generates considerable extra investment activities.

Exporting Financial Institutions Management via Foreign Direct Investment Mergers and Acquisitions
Allen N. Berger, Claudia M. Buch, G. DeLong
Journal of International Money and Finance,
No. 3,
2004
Abstract
We test the relevance of the new trade theory and the traditional theory of comparative advantage for explaining the geographic patterns of international M&As of financial institutions between 1985 and 2000. The data provide statistically significant support for both theories. We also find evidence that the U.S. has idiosyncratic comparative advantages at both exporting and importing financial institutions management.

Innovation cooperation: experiences from East and West Germany
Jutta Günther
Science and Public Policy,
2004
Abstract
This paper deals with innovation cooperation as a means to support the ongoing catch-up process of the East German economy. Against prevalent beliefs, it can be shown that East German enterprises are more often involved in innovation co-operation than West German firms, and differences in cooperation partner priorities only reflect the given structural differences between the two regions. While cooperating enterprises in East and West Germany are clearly more innovative than their non-cooperating counterparts, a productivity advantage of these firms is (so far) only observable in West Germany. Reasons for this surprising finding are discussed.

“Law on loyalty to collectively agreed standards“ - no means for adjusting competitive conditions in construction industry
Andrea Besenthal
Wirtschaft im Wandel,
No. 2,
2004
Abstract
Due to the increasing competition from abroad which is able to offer services for lower prices because of lower wage standards the stress of competition intensifies in Germany. With regard to West Germany the East German companies - paying lower wages – represent an immediate business competition. The supporter of the Tariftreuegesetze (laws concerning the construction industry which restrict public contracts only to contractors who pay union wages) see the laws` advantage in eliminating the existing differences in competitive conditions, which emerge from differences on the wage level. The IWH study concludes that the named wage laws do not seem necessary from an economic point of view.

East German Construction Industry December 2003: Favorable weather conditions support building business
Brigitte Loose
Wirtschaft im Wandel,
No. 1,
2004
Abstract
Laut Umfrage des IWH unter 300 ostdeutschen Bauunternehmen wurde die Geschäftslage zum Jahresende 2003 – wie zu dieser Jahreszeit üblich – nicht mehr ganz so gut beurteilt wie noch im Herbst. Etwas mehr als die Hälfte der Unternehmen stufte das aktuelle Baugeschäft aber immer noch mit „gut“ oder „eher gut“ ein. Maßgeblich hierfür waren die vergleichsweise milden Temperaturen, die im Dezember kaum zu witterungsbedingten Ausfällen geführt haben. Darüber hinaus bewirken verschiedene temporäre Impulse, dass das Geschäftsklima am Bau nun bereits seit Frühjahr 2003 das jeweils vergleichbare Vorjahresniveau überschreitet.

IWH Economic Outlook 2004: No longer waiting for the economic upturn
Wirtschaft im Wandel,
No. 1,
2004
Abstract
The Economic Outlook 2004 updates the IWH forecast for 2004 and gives a first outlook on 2005. The world recovery is mainly driven by the strong economic impulses from the USA. Whereas the upturn in the US is domestically driven, the impetus in the euro area is coming from external trade. Nonetheless in Germany corporate investment activity still is slow. Although the tax reductions in 2004 will support private consumption, its overall economic impulse will be weak. German GDP in 2004 will increase 1.6% and 1.8% in 2005. At the labour market no clear improvement can be expected till the second half of 2004; on a yearly average employment will decrease by 100 000 persons in 2004. Albeit the partly broad forward third instalment of the tax reform, fiscal policy will have a restrictive aim. Monetary policy on the other hand will continue to be highly expansive, but as the output gap shrinks the ECB can be expected to increase interest rates moderately.

Effects of the promotion of investment in East Germany
Joachim Ragnitz
IWH Discussion Papers,
No. 186,
2003
Abstract
Investment in East Germany is heavily subsidized. Econometric estimates based on a treatment approach show that the level of investment is significantly higher in firms being supported by state aid. Nevertheless, capital productivity is lower in East Germany, indicating a misallocation of capital. Additionally, there are negative effects in West Germany due to negative crowding-out effects. Therefore state aid in East Germany should be reduced in the medium run.

Germany 2004: Only a transitory economic stimulus from moving tax cuts forward
Wirtschaft im Wandel,
No. 9,
2003
Abstract
In summer 2003 the German economy once again did not overcome the stagnation, which by now lasted three years. Only by the end of this year the German economy will begin to receive stronger support from a then further improved world economy. In the past months both US and European monetary policy have provided sufficient liquidity by lowering interest rates. In the USA, additional support is provided by fiscal policy; tax reductions and rebates increase domestic demand. Overall, Gross Domestic Product in the US will increase by 2.1% this year; in the euro area GDP will merely expand by a modest 0.8%. For Germany one of its key sectors will not be able to lift the economy as usual and GDP, when compared to last year, will only stagnate. Provided by the brought forward tax reform 2000 the coming year will begin with a stimulus to the German economy. The tax reductions, though, will have limited effect on aggregate production, as the increased consumption will not be able to stimulate investment. Accounting for calendar effects GDP in Germany will increase by at least 1% in 2004 compared with this year, but due to several additional working days in 2004, the unadjusted rate of expansion will be 1.7%. No substantial improvements are expected for the job market.
