Technology management in the company of the future

This paper develops new conceptual ideas on the role of technology management in future companies. It draws consequences for their operatins, and it suggests new perspectives that arise from current trends in company development. It argues that technology management needs to address, in a differentiated manner, the problems which airse during the development process of companies and markets. Particular emphasis is placed on the demand of systems producers on technology management.     

A monetary economy with counterfeiting

We apply a search-theoretic model of fiat money to study the equilibria in which counterfeit money is accepted. Circulation of counterfeit money presupposes that the agents are impatient and that the punishment for holding it is not too severe. When the stock of genuine money is small counterfeit money may improve the efficiency of the economy. We establish that a monetary economy can be created with private provision of (counterfeit) money as long as the ruler has control over punishments. Totally noncooperative provision will fail as the economy will become flooded with money.     

Optimal macroeconomic policies in a financial and economic crisis: a case study for Slovenia

In this paper, we study different and, in particular, “optimal” reactions of fiscal (and to some extent monetary) policies to the financial and economic crisis of 2007–2009 in Slovenia, a small open economy that is part of the Economic and Monetary Union (EMU). Using an econometric model of the Slovenian economy, we simulate the effects of the global crisis under the assumption of no-policy reactions, i.e. assuming that macroeconomic policies are conducted without attempting to deal with the effects of the crisis. Next, we study the possibilities of fiscal policy reducing or even annihilating the effects of the crisis. We also investigate the optimal reaction of fiscal policies based on the assumption that Slovenian policy-makers behave as though they were optimizing an objective function. We show that optimal policies call for only a very modestly active countercyclical role of fiscal policies. There are strong trade-offs between countercyclical fiscal policies and the requirements of fiscal solvency.     

The short and long-run interdependencies between the Eurozone and the USA

We estimate quarterly cointegrating vector autoregressive models for the Eurozone and the USA based on long-run restrictions derived from a dynamic open economy model. Three long-run relations between the Eurozone and the USA emerge: relative purchasing power parity, international interest parity and a stationary output gap between the two economies. Generalized impulse response functions show differences in the dynamic adjustment of the two economies. Due to the I(1)-characteristic of both output series and the stability conditions imposed by the long-run equilibrium relationships, shocks to the model produce level effects only, while growth rates converge to their long-run averages.

Spatial growth and industry age

Between 1970 and 2000 employment growth across U.S. counties exhibited very different patterns in manufacturing and services. Whereas manufacturing employment growth was negatively related to initial manufacturing employment across the entire distribution of counties, service employment growth was positively related to initial service employment for intermediate sized counties. This paper presents a theory to rationalize these facts. Local sectoral growth is driven by technological diffusion across space and depends on the age of the sector. The theory correctly predicts the relation between county employment growth and initial county employment in manufacturing at the turn of the 20th century.     

Corrigendum to “Stable matchings and preferences of couples” [J. Econ. Theory 121 (1) (2005) 75–106]

We correct an omission in the definition of the domain of weakly responsive preferences introduced in [B. Klaus, F. Klijn, Stable matchings and preferences of couples, J. Econ. Theory 121 (2005) 75–106] or KK05 for short. The proof of the existence of stable matchings [KK05, Theorem 3.3] and a maximal domain result [KK05, Theorem 3.5] are adjusted accordingly.     

Voluntary Environmental Agreements vs. Emission Taxes in Strategic Trade Models

The purpose of the paper is to narrow the gap between the widespread use of voluntary agreements and research on the rationale of such approaches. A topical example are voluntary agreements of many industries to reduce carbon dioxide emissions because of global warming. If the industry anticipates that taxes and fees will be introduced in the coming years, it seems rational to act in advance in order to mitigate the tax levels.The conventional approach in strategic trade and tax models was to look at a two-stage game where governments set taxes first and then firms react. In such a policy regime the government is concerned about the international competitiveness of its firms and sets taxes below marginal damages. In this paper, we consider a policy regime with a reversed timing. Firms commit themselves in the face of emission taxes to abatement efforts and to lower levels of the environmentally intensive output. Then the government introduces the tax. Under this timing of strategies the tax is equal to marginal damage. Firms waive profit and reduce output in order to use less of the polluting input. The reward for this behavior will be a less strict use of policy instruments and hence lower abatement costs in the near future.
