Intellectual Property Rights Policy, Competition and Innovation

Journal of the European Economic Association,
No. 1,

Abstract
To what extent and in what form should the intellectual property rights (IPR) of innovators be protected? Should a company with a large technology lead over its rivals receive the same IPR protection as a company with a more limited advantage? In this paper, we develop a dynamic framework for the study of the interactions between IPR and competition, in particular to understand the impact of such policies on future incentives. The economy consists of many industries and firms engaged in cumulative (step-by-step) innovation. IPR policy regulates whether followers in an industry can copy the technology of the leader. We prove the existence of a steady-state equilibrium and characterize some of its properties. We then quantitatively investigate the implications of different types of IPR policy on the equilibrium growth rate and welfare. The most important result from this exercise is that full patent protection is not optimal; instead, optimal policy involves state-dependent IPR protection, providing greater protection to technology leaders that are further ahead than those that are close to their followers. This is because of a trickle-down effect: providing greater protection to firms that are further ahead of their followers than a certain threshold increases the R&D incentives also for all technology leaders that are less advanced than this threshold.

Political Institutionalisation and Governance of the German Metropolitan Regions: A Comparative Study
Peter Franz
Wirtschaft im Wandel,
No. 11,
2011
Abstract
In Germany, some cities and districts try to react to the challenges of global location competition by the constitution of metropolitan regions. Thus new forms of intermunicipal co-operation on a regional scale emerge. Within the context of a national policy for spatial development eleven such metropolitan regions have been defined in Germany, and local activities supporting their constitution were encouraged. In spite of differing results and success in the eleven regions this process of political institutionalisation has led to partially similar institutional forms. This study compares the institutionalisaton process in the German metropolitan regions with the help of an idealtype model of institutionalisation steps. In addition, the design of the comparative study also allows testing potential effects of intervening factors as the regions’ monocentricity / polycentricity and the existence of Laender borders in a region on cooperative success. The study comes to the result that so far only few metropolitan regions have reached the stage of advanced institutionalisation and co-operation. The diversity of the institutionalisation paths prevents a „best practice“ recommendation at the present state of knowledge. As the constitution process in the regions still proceeds in a highly dynamic way, this study should be repeated within a five years’ period.

Labor Demand During the Crisis: What Happened in Germany?
Claudia M. Buch
IZA. Discussion Paper No. 6074,
2011
Abstract
In Germany, the employment response to the post-2007 crisis has been muted compared to other industrialized countries. Despite a large drop in output, employment has hardly changed. In this paper, we analyze the determinants of German firms’ labor demand during the crisis using a firm-level panel dataset. Our analysis proceeds in two steps. First, we estimate a dynamic labor demand function for the years 2000-2009 accounting for the degree of working time flexibility and the presence of works councils. Second, on the basis of these
estimates, we use the difference between predicted and actual employment as a measure of labor hoarding as the dependent variable in a cross-sectional regression for 2009. Apart from total labor hoarding, we also look at the determinants of subsidized labor hoarding through short-time work. The structural characteristics of firms using these channels of adjustment differ. Product market competition has a negative impact on total labor hoarding but a positive effect on the use of short-time work. Firm covered by collective agreements hoard less labor overall; firms without financial frictions use short-time work less intensively.

Government Interventions in Banking Crises: Effects of Alternative Schemes on Bank Lending and Risk-taking
Diemo Dietrich, Achim Hauck
Scottish Journal of Political Economy,
No. 2,
2012
Abstract
We analyse the effects of policy measures to stop the fall in loan supply following a banking crisis. We apply a dynamic framework in which a debt overhang induces banks to curtail lending or to choose a fragile capital structure. Government assistance conditional on new banking activities, like on new lending or on debt and equity issues, allows banks to influence the scale of the assistance and to externalise risks, implying overinvestment or excessive risk taking or both. Assistance without reference to new activities, like granting lump sum transfers or establishing bad banks, does not generate adverse incentives but may have higher fiscal costs.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
North American Journal of Economics and Finance,
No. 3,
2011
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts based on a number of forecasting techniques from the literature using a panel of ten industrialized countries during the period of 1988 to 2007. To capture expected inflation, we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

Knowledge Sharing Through Informal Networking: An Overview and Agenda
Michael Schwartz, Christoph Hornych
International Journal of Knowledge-Based Development,
No. 3,
2011
Abstract
Informal inter-organizational networks provide manifold opportunities to organize the transfer of information, knowledge and technology between actors. The importance of informal networks as a channel of knowledge transfer is widely acknowledged by academics and practitioners. However, there is a significant lack of discussion on their theoretical foundations and systematic empirical research on the origins, dynamics and effects of informal networking. The objective of this paper is threefold. First, we review the fragmented academic discussion of the notion of informal networking, thereby focusing on how these relationships emerge initially and what conditions (presumably) are required to make them a mutually fruitful and sustainable channel of the transfer of information and knowledge. Second, we give an up-to-date overview over most important and recent studies trying to disentangle the mechanisms of inter-organizational informal networking. Finally, we outline an agenda of future research directions which we encourage researchers to pursue in future empirical studies. Overall, six important research gaps are identified.

German Economy Recovers Surprisingly Quickly from Last Year’s Recession
Wirtschaft im Wandel,
No. 9,
2010
Abstract
The German economy recovers surprisingly quickly from last year’s recession. For this year, we expect GDP to grow by 3.5%. Next year, when GDP growth should reach a rate of 2%, the general government deficit is likely to fall below the 3% mark of the Stability and Growth pact – if the government indeed realizes the stabilization program it decided on this summer. Unemployment will continue to decline.
We see three main causes for this favorable development: first, the German economy benefits strongly from the high growth dynamics in emerging markets, since German firms are well positioned for producing investment goods that are particularly sought-after in these countries. Second, growing demand for labor in Germany means that employment and labor income is on the rise. Partly, this is the reward for a long time of low wage rises that have made labor in Germany competitive again. Third, the expansive monetary policy in the euro area is particularly stimulating since here debt levels of private households and firms are moderate and therefore do not dampen the stimulating effects of low interest rates, as they do in many euro area partner countries with highly indebted private and public agents.

International Bank Portfolios: Short- and Long-Run Responses to Macroeconomic Conditions
S. Blank, Claudia M. Buch
Review of International Economics,
No. 2,
2010
Abstract
International bank portfolios constitute a large component of international country portfolios. Yet, banks’ response to international macroeconomic conditions remains largely unexplored.We use a novel dataset on banks’ international portfolios to answer three questions. First, what are the long-run determinants of banks’ international portfolios? Second, how do banks’ international portfolios adjust to short-run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration?We find that, in the long-run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short-run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity-type variables.
