Abstract
Real costs of freight transportation have strong increased in Russia particularly during the period of price liberalization 1992–93. This paper investigates possible connections between rising transport costs and the evolution of the size structure of the system of cities in the Russian Federation and its federal subjects. Empirical findings suggest that under conditions of a closed system agglomeration processes according to the predictions of the model of Tabuchi et al. (2005) would have taken place especially in the periphere regions of the North and Far East.

Does Qualification Drive Innovation? A Microeconometric Analysis Using Linked-employer-employee Data
Bianca Brandenburg, Jutta Günther, Lutz Schneider
IWH Discussion Papers,
No. 10,
2007
Abstract
Degree-level science and engineering skills as well as management and leadership skills are often referred to as a source of innovative activities within companies. Broken down by sectoral innovation patterns, this article examines the role of formal education and actual occupation for product innovation performance in manufacturing firms within a probit model. It uses unique micro data for Germany (LIAB) that contain detailed information about innovative activities and the qualification of employees. We find significant differences of the human capital endowment between sectors differentiated according to the Pavitt classification. Sectors with a high share of highly skilled employees engage in product innovation above average (specialized suppliers and science based industries). According to our hitherto estimation results, within these sectors the share of highly skilled employees does not, however, substantially increase the probability to be an innovative firm.

The Euro and Cross-Border Banking: Evidence from Bilateral Data
S. Blank, Claudia M. Buch
Comparative Economic Studies,
No. 3,
2007
Abstract
Has the introduction of the Euro fostered financial integration in Europe? We answer this question using a data set of banks’ bilateral foreign assets and liabilities provided by the Bank for International Settlements. The data cover the pre-Euro period (1995–1998) and the post-Euro period (1999–2005). We use information from 10 OECD reporting countries and all OECD recipient countries. Gravity regressions show a positive and significant impact of the Euro on bilateral financial linkages. This effect is stronger and more robust for banks’ foreign assets than for their foreign liabilities.

FDI and Domestic Investment: An Industry-level View
Claudia M. Buch
CEPR. Discussion Paper No. 6464,
2007
Abstract
Previous empirical work on the link between domestic and foreign investment provides mixed results which partly depend on the level of aggregation of the data. We argue that the aggregated home country implications of foreign direct investment (FDI) cannot be gauged using firm-level data. Aggregated data, in turn, miss channels through which domestic and foreign activities interact. Instead, industry-level data provide useful information on the link between domestic and foreign investment. We theoretically show that the effects of FDI on the domestic capital stock depend on the structure of industries and the relative importance of domestic and multinational firms. Our model allows distinguishing intra-sector competition from inter-sector linkage effects. We test the model using data on German FDI. Using panel cointegration methods, we find evidence for a positive long-run impact of FDI on the domestic capital stock and on the stock of inward FDI. Effects of FDI on the domestic capital stock are driven mainly by intra-sector effects. For inward FDI, inter-sector linkages matter as well.

Spillover Effects of Spatial Growth Poles - a Reconciliation of Conflicting Policy Targets?
Alexander Kubis, Mirko Titze, Joachim Ragnitz
IWH Discussion Papers,
No. 8,
2007
Abstract
Regional economic policy faces the challenge of two competing policy goals - reducing regional economic disparities vs. promoting economic growth. The allocation of public funds has to weigh these goals particularly under the restriction of scarce financial re- sources. If, however, some region turns out to be a regional growth pole with positive spillovers to its disadvantaged periphery, regional policies could be designed to recon- cile the conflicting targets. In this case, peripheral regions could indirectly participate in the economic development of their growing cores. We start our investigation by defining and identifying such growth poles among German regions on the NUTS 3 administrative level based on spatial and sectoral effects. Using cluster analysis, we determine significant characteristics for the general identification of growth poles. Patterns in the sectoral change are identified by means of the change in the employment. Finally, we analyze whether and to what extent these growth poles ex- ert spatial spillover effects on neighbouring regions and thus mitigate contradictory in- terests in regional public policy. For this purpose, we apply a Spatial-Cross-Regressive- Model (SCR-Model) including the change in the secondary sector which allows to con- sider functional economic relations on the administrative level chosen (NUTS 3).

Broadband Investment and the Threat of Regulation: Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
Review of Network Economics,
2007
Abstract
Recently, investments in new generation networks in Germany have been curtailed, since potential investors required this new network be unregulated. To develop a regulator's strategy that allows investments to occur but prevents monopolistic prices, we model an investor's decision problem under a threat of regulation. We show that the mere threat of a regulator's intervention may prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both the investment decision and the investor's price via her signals on regulation probability and price.

Aid and Economic Freedom: An Empirical Investigation Using the Heritage Index
Tobias Knedlik, Franz Kronthaler
Journal of Development Perspectives,
No. 3,
2007
Abstract
The paper explores the relationships between economic freedom on the one side and development aid and IMF credit as approximation for conditional aid on the other side. After a short review of current literature, the paper develops a simple panel regression model to evaluate the relationships. In contrast to previous research, our results allow the rejection of the hypothesis that IMF credit increases economic freedom and that development aid is not contributing to economic freedom. It could not be shown that countries can be pushed towards economic freedom by aid conditions. The paper discusses explanations of the empirical findings.

The East German Cement Cartel: Cartel Efficiency and Policy after Economic Transformation
Ulrich Blum
Eastern Economic Review,
2007
Abstract
In 2003 the German Antitrust Commission (GAC) proved the existence of a cartel in the German cement industry. The German cement producers involved in the case were fined € 661 million for having established quotas to extract additional rents. One of the main centers of this cartel was East Germany, where the East German Cement Combine with its giant facilities had been sold, in the early 1990s, to four large producers by Treuhand in the process of privatizing the economy. Only in respect to in this market did all defendants concede having had a part in forming a cartel.
In this paper, we challenge the argument of excess revenue that the GAC puts forward for the East German market. We argue that legal evidence does not necessarily translate into economic evidence. We show that demand for cement is realized in geographical and, to a more limited extent, in product space. Thus, in the absence of cartels we would expect monopolistic competition to prevail. We argue that any transition in the market regime, from the cartel to the post cartel period, must be traceable in the individual firm’s demand function which differs from the clients’ demand function because of costs for spatial and product differentiation. Within the framework of an econometric model, we cannot identify any structural changes in demand. Most likely, imports from Poland and the Czech Republic were dumped into the East German market and some medium sized producers were responsible for the cartel never working.
Finally the paper shows how difficult it is to generate competition in certain industries even under the umbrella of a well-established market economy, i.e. that of West Germany, and that the openness of the economy, i.e. trans-border shipments, are decisive.
