Firm-Specific Determinants of Productivity Gaps between East and West German Industrial Branches
Johannes Stephan, Karin Szalai
IWH Discussion Papers,
Nr. 183,
2003
Abstract
Industrial productivity levels of formerly socialist economies in Central East Europe (including East Germany) are considerably lower than in the more mature Western economies. This research aims at assessing the reasons for lower productivities at the firm level: what are the firm-specific determinants of productivity gaps. To assess this, we have conducted an extensive field study and focussed on a selection of two important manufacturing industries, namely machinery manufacturers and furniture manufacturers, and on the construction industry. Using the data generated in field work, we test a set of determinant-candidates which were derived from theory and prior research in that topic. Our analysis uses the simplest version of the matched-pair approach, in which first hypothesis about relevant productivity level-determinants are tested. In a second step, positively tested hypothesis are further assessed in terms of whether they also constitute firm-specific determinants of the apparent gaps between the firms in our Eastern and such in our Western panels. Our results suggest that the quality of human capital plays an important role in all three industrial branches assessed. Amongst manufacturing firms, networking activities and the use of modern technologies for communication are important reasons for the lower levels of labour productivity in the East. The intensity of long-term strategic planning on behalf of the management turned out to be relevant only for machinery manufacturers. Product and process innovations unexpectedly exhibit an ambiguous picture, as did the extent of specialisation on a small number of products in the firms’ portfolio and the intensity of competition.

Does Transparency of Central Banks Produce Multiple Equilibria on Currency Markets?
Axel Lindner
IWH Discussion Papers,
Nr. 178,
2003
Abstract
A recent strand of literature (see Morris and Shin 2001) shows that multiple equilibria in models of markets for pegged currencies vanish if there is slightly diverse information between traders. It is known that this approach works only if there is not too precise common knowledge in the market. This has led to the conclusion that central banks should try to avoid making their information common knowledge. We present a model in which more transparency of the central bank means better private information, because each trader utilizes public information according to her own private information. Thus, transparency makes multiple equilibria less likely.

Environmental policy under product differentiation and asymmetric costs - Does Leapfrogging occur and is it worth it?
Jacqueline Rothfels
IWH Discussion Papers,
Nr. 124,
2000
Abstract
This paper studies the influence of environmental policies on environmental quality, domestic firms, and welfare. Point of departure is Porter’s hypothesis that unilateral environmental regulation may enhance the competitiveness of domestic firms. This hypothesis has recently received considerable support in theoretical analyses, especially if imperfectly competitive markets with strategic behavior on behalf of the agents are taken into account. Our work contributes to this literature by explicitely investigating the implications of asymmetric cost structures between a domestic and a foreign firm sector. We use a partial-equilibrium model of vertical product differentiation, where the consumption of a product causes environmental harm. Allowing for differentiated products, the domestic industry can either assume the market leader position or lag behind in terms of the environmental quality of the produced product. Assuming as a benchmark case that the domestic industry lags behind, we investigate the possibility of the government to induce leapfrogging of the domestic firm, i.e. a higher quality produced by the domestic firm after regulation than that of the competitor prior to regulation. It is shown that in the case of a cost advantage for the domestic firm in the production process the imposition of a binding minimum quality standard can serve as a tool to induce leapfrogging. In case of a cost disadvantage the same result can be achieved through an adequate subsidization of quality dependend production costs. Thus, careful regulation enables the domestic firm in both scenarios to better its competitive position against foreign competitors and to earn larger profits. Additionally, environmental quality and welfare can be enhanced.

Uncovered Workers in Plants Covered by Collective Bargaining: Who Are They and How Do They Fare?
Boris Hirsch, Philipp Lentge, Claus Schnabel
Abstract
In Germany, employers used to pay union members and non-members in a plant the same union wage in order to prevent workers from joining unions. Using recent administrative data, we investigate which workers in firms covered by collective bargaining agreements still individually benefit from these union agreements, which workers are not covered anymore, and what this means for their wages. We show that about 9 percent of workers in plants with collective agreements do not enjoy individual coverage (and thus the union wage) anymore. Econometric analyses with unconditional quantile regressions and firm-fixed-effects estimations demonstrate that not being individually covered by a collective agreement has serious wage implications for most workers. Low-wage non-union workers and those at low hierarchy levels particularly suffer since employers abstain from extending union wages to them in order to pay lower wages. This jeopardizes unions' goal of protecting all disadvantaged workers.
