Monopoly Welfare Losses in the Long Run

Irrespective of the merit of any previous approaches to assess the deadweight loss due to monopoly they are all static in character and disregard the long term effects of monopoly power. Taking into account the long run consequences of monopoly power within the framework of the new growth theory yields startling new insights. In contrast to the Schumpeterian view that there is a tradeoff between static inefficiency and dynamic progressiveness monopoly power is shown to entail not only static welfare losses but also to exert an adverse influence on economic growth. Once this is granted the long run welfare loss due to monopoly can be shown to dwarf the static losses so far treated in the economics literature.     

INPUT–OUTPUT ANALYSIS: THE NEXT 25 YEARS

This year marks the 25th anniversary of the International Input–Output Association and the 25th volume of Economic Systems Research. To celebrate this anniversary, a group of eight experts provide their views on the future of input–output. Looking forward, they foresee progress in terms of data collections, methods, theory testing, and focus and scope.     

EFFECTS OF SECTOR AGGREGATION ON CO2 MULTIPLIERS IN MULTIREGIONAL INPUT–OUTPUT ANALYSES

The past few years have seen the emergence of several global multiregional input–output (MRIO) databases. Due to the cost and complexity of developing such extensive tables, industry sectors are generally represented at a rather aggregate level. Currently, one of the most important applications of input–output analysis is environmental assessments, for which highly aggregate sectors may not be sufficient to yield accurate results. We experiment with four of the most important global MRIO systems available, analyzing the sensitivity of a set of aggregate CO₂ multipliers to aggregations in the MRIO tables used to calculate them. Across databases, we find (a) significant sensitivity to background system detail and (b) that sub-sectors contained within the same aggregate MRIO sector may exhibit highly different carbon multipliers. We conclude that the additional information provided by the extra sector detail may warrant the additional costs of compilation, due to the heterogeneous nature of economic sectors in terms of their environmental characteristics.     

Marketingerfolg richtig messen: Optimale Kennzahlensysteme

Zusammenfassung  Wie kann man zuverl?ssige Methoden entwickeln, um die Erfolgswirkungen von Marketingma?nahmen auf den Unternehmenswert zu messen? Am Anfang steht dabei die Frage, was Marketingerfolg eigentlich ist. Eine reine Fokussierung auf die Stakeholdergruppe der Kunden reicht hier nicht aus. Andere, durch Marketing ebenfalls erreichte Interessensgruppen wie z.B. Investoren oder Mitarbeiter müssen auch betrachtet werden. Und das alles vor dem Hintergrund moderierender Kontextfaktoren wie etwa der Unternehmensstrategie oder der Branche. Dipl.-Kfm.

Financing Constraints and the Timing of Innovations in the German Services Sector

Using newly available data at the firm level, this study provides convincing evidence of the importance of financial constraints in explainingthe timing of innovations in the German services sector. Based on a dynamic model of firms' optimalR & D behavior under financial constraints, we estimate various versions of aneconometric specification of the model with dichotomous innovation data by using a univariateordered probit model. Additionally, a new estimation technique is applied to account forthe scaling of the regressor variables. Our results are consistent with the theoretical view that,because of capital market imperfections, internal finance should be an important determinant ofinnovative activities by private firms not only in the manufacturing sector but as well as inthe services sector.

Two concepts of monotonicity in two-person bargaining theory

Monotonicity has been suggested as a principle of fairness and a principle of bargaining. It has been proposed as a substitute to the “independence of irrelevant alternatives” axiom in bargaining solutions and thus applied to the determination of wages and employment. In this paper we will discuss the Kalai-Smorodinsky solution and show that it does not correspond to the monotonicity notion which follows from the “principle of bargaining” idea.
