Bertrand Competition with an Asymmetric No-discrimination Constraint

Journal of Industrial Economics,
No. 1,
2013
Abstract
Regulators and competition authorities often prevent firms with significant market power, or dominant firms, from practicing price discrimination. The goal of such an asymmetric no-discrimination constraint is to encourage entry and serve consumers' interests. This constraint prohibits the firm with significant market power from practicing both behaviour-based price discrimination within the competitive segment and third-degree price discrimination across the monopolistic and competitive segments. We find that this constraint hinders entry and reduces welfare when the monopolistic segment is small.

Regional Origins of Employment Volatility: Evidence from German States
Claudia M. Buch, M. Schlotter
Empirica,
No. 1,
2013
Abstract
Greater openness for trade can have positive welfare effects in terms of higher growth. But increased openness may also increase uncertainty through a higher volatility of employment. We use regional data from Germany to test whether openness for trade has an impact on volatility. We find a downward trend in the unconditional volatility of employment, paralleling patterns for output volatility. The conditional volatility of employment, measuring idiosyncratic developments across states, in contrast, has remained fairly unchanged. In contrast to evidence for the US, we do not find a significant link between employment volatility and trade openness.

Effects of Entrepreneurship Education at Universities
S. Laspita, H. Patzelt, Viktor Slavtchev
Jena Economic Research Papers,
No. 25,
2012
Abstract
This study analyzes the impact of entrepreneurship education at universities on the intentions of students to become entrepreneurs or self-employed in the short-term (immediately after graduation) and in the long-term (five years after graduation). A difference-in-differences approach is applied that relates changes in entrepreneurial intentions to changes in the attendance of entrepreneurship classes in the same period. To account for a potential bias due to self-selection into entrepreneurship classes, only individuals having no prior entrepreneurial intentions are analyzed. Our results indicate a stimulating effect of entrepreneurship education on students’ intentions to become entrepreneurs or self-employed in the long-term but a discouraging effect on their intentions in the short-term. These results support the conjecture that entrepreneurship education provides more realistic perspectives on what it takes to be an entrepreneur, resulting in ‘sorting’. Overall, the results indicate that entrepreneurship education may improve the quality of labor market matches, the allocation of resources and talent, and increase social welfare. Not distinguishing between short- and long-term intentions may lead to misleading conclusions regarding the economic and social impact of entrepreneurship education.

Enhancing Market Power by Reducing Switching Costs
Jan Bouckaert, Hans Degryse, Thomas Provoost

Abstract
A proportional decrease in switching costs increases competition and social welfare. However, a lump-sum decrease in switching costs softens competition and does not invariably increase social welfare.

Intellectual Property Rights Policy, Competition and Innovation
Daron Acemoglu, Ufuk Akcigit
Journal of the European Economic Association,
No. 1,
2012
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.

The Political Setting of Social Security Contributions in Europe in the Business Cycle
Toralf Pusch, Ingmar Kumpmann
IWH Discussion Papers,
No. 4,
2011
Abstract
Social security revenues are influenced by business cycle movements. In order to
support the working of automatic stabilizers it would be necessary to calculate social insurance contribution rates independently from the state of the business cycle. This paper investigates whether European countries set social contribution rates according to such a rule. By means of VAR estimations, country-specific effects can be analyzed – in contrast to earlier studies which used a panel design. As a result, some countries under investigation seem to vary their social contribution rates in a procyclical way.

Is East Germany Catching Up? A Time Series Perspective
Bernd Aumann, Rolf Scheufele
Post-Communist Economies,
2010
Abstract
This article assesses whether the economy of East Germany is catching up with the West German region in terms of welfare. While the primary measure for convergence and catching up is per capita output, we also look at other macroeconomic indicators such as unemployment rates, wage rates and production levels in the manufacturing sector. In contrast to existing studies of convergence between regions of the reunified Germany, our approach is based purely upon the time series dimension and is thus directly focused on the catching up process in East Germany as a region. Our testing set-up includes standard ADF unit root tests as well as unit root tests that endogenously allow for a break in the deterministic component of the process. We find evidence of catching up for East Germany for most of the indicators. However, the convergence speed is slow, and thus it can be expected that the catching up process will take further decades until the regional gap is closed.

Interactive Dynamic Capabilities and Regenerating the East German Innovation System
N. von Tunzelmann, Jutta Günther, Katja Wilde, Björn Jindra
Contributions to Political Economy,
2010
Abstract
The paper sets out a specification of capabilities and competencies derived from Sen’s work on consumer capabilities and welfare economics. This approach is one that proves remarkably easy to generalise, first to producer and supplier capabilities, and thence to interactive and dynamic capabilities. The approach is then applied via the consequential perspectives of regional systems of innovation and network alignment to the case of the efforts to regenerate the innovation system in East Germany since reunification. It is seen that this process can be divided into three periods, of which the most recent appears to meet some of the theoretical requirements for effective interactive capabilities. It is less clear that the criteria for dynamic capabilities—which involve considerations of speed-up and flexibility, to meet the market requirements in real time—have yet been taken sufficiently seriously.

Transmission of Nominal Exchange Rate Changes to Export Prices and Trade Flows and Implications for Exchange Rate Policy
Mathias Hoffmann, Oliver Holtemöller
Scandinavian Journal of Economics,
2010
Abstract
We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these two parameters for which flexible and fixed exchange rates are superior with respect to welfare as measured by a representative household's utility level. We estimate the two parameters for six non-EMU European countries (Czech Republic, Hungary, Poland, Slovakia, Sweden, and the UK) using a heterogeneous dynamic panel approach.

Growth, Employment, Poverty Alleviation and Institutional Development – Lessons from Country Cases – An Introduction
Tobias Knedlik, Karl Wohlmuth
African Development Perspectives Yearbook, No. 14,
2009
Abstract
Economic growth is a central concept in judging the progress of economic development. Since the early years of economic sciences, economists aim to explain the differences in the production of goods and services among economies. Economic policy focuses on economic growth as the basis for the well-being of nations. The simple idea is that the extension of the productive capacity and finally the increase of consumption possibilities in an economy is the basis of all policies aiming to increase a nation’s welfare. It is therefore not surprising that aims of development policy are often linked to specific economic growth targets. So the United Nation’s Millennium Development Goals are assumed only to be achieved if a certain level of economic growth can be reached.
