Der Intra-Extra-Media-Vergleich — ein wenig genutztes Analyseinstrument und seine methodischen Anforderungen

The article addresses the methodological demands which allow drawing conclusion about a potential change in news selection from a comparison of content analysis data and extra-media statistics. Based on arguments by Karl Erik Rosengren, the design and admissibility of such studies is discussed. Then the demands for the events to be analyzed, for the content analysis data and for the extra-media statistics are dealt with. The application of the standards developed and some problems in empirical procedures are illustrated with a small study. It asks whether news selection has changed over the past fifty years in a way that accidents and damage have drawn more attention to themselves in news coverage. With respect to some relevant events, data from a content analysis of three German national newspapers are related to external statistics. The analyses show that news selection in the papers studied has temporarily changed for the events under consideration, but that no long-term trend — primarily no trend towards increasing negativism — could be made out.     

What does “clean” really mean? The implicit framing of decontextualized experiments

It is standard in experimental economics to use decontextualized designs where payoff structures are presented using neutral language. Here we show that cooperation in such a neutrally framed Prisoner’s Dilemma is equivalent to a PD framed as contributing to a cooperative endeavour. Conversely, there is substantially less cooperation in a PD framed as a competition. We conclude that in a decontextualized context, our participants by default project a cooperative frame onto the payoff structure.     

The analysis of unbalanced linear models with variance components

Statistical inference for fixed effects, random effects and components of variance in an unbalanced linear model with variance components will be discussed. Variance components will be estimated by Restricted Maximum Likelihood. Iterative procedures for computing the estimates, such as Fisher scoring and the EM-algorithm, are described.     

Community–Industry Contracting over Natural Resource use in a Context of Weak Property Rights: The Case of Indonesia

Decentralization in Indonesia has resulted in an increased influence of local communities over the terms of logging agreements with timber companies. The outcomes of such community–company negotiations vary significantly across communities. What are the conditions that cause this variation, and how can the outcomes be more effectively and efficiently influenced by third-party actors such as the local government or NGOs? This paper addresses these questions by developing a game-theoretic model to illustrate the strategic interactions between communities and companies. The model allows for endogeneity of de facto property rights and bargaining positions. We show that third-party actions to improve the community’s bargaining position by raising its reservation utility may result in an increase in the area logged and thereby harm the environment. Our results indicate that the strategy of intervention matters. In particular, strategies that raise the sensitivity of interventions to local logging threats are likely to be more cost-effective in supporting communities and reducing forest degradation than more indiscriminatory strategies. The model will be relevant to other situations where communities negotiate contracts over natural resource use with outside actors in a context of weak property rights, a situation increasingly observed in other developing countries.     

Monetary Policy in the Open Economy Revisited: Price Setting and Exchange-Rate Flexibility

This paper develops a welfare-based model of monetary policy in an open economy. We examine the optimal monetary policy under commitment, focusing on the nature of price adjustment in determining policy. We investigate the implications of these policies for exchange-rate flexibility. The traditional approach maintains that exchange-rate flexibility is desirable in the presence of real country-specific shocks that require adjustment in relative prices. However, in the light of empirical evidence on nominal price response to exchange-rate changes—specifically, that there appears to be a large degree of local-currency pricing (LCP) in industrialized countries—the expenditure-switching role played by nominal exchange rates may be exaggerated in the traditional literature. In the presence of LCP, we find that the optimal monetary policy leads to a fixed exchange rate, even in the presence of country-specific shocks. This is true whether monetary policy is chosen cooperatively or non-cooperatively among countries.     

The front end of innovation in an era of industry convergence: evidence from nutraceuticals and functional foods

Industry convergence, defined as a 'blurring' of boundaries between industries, induced by converging value propositions, technologies and markets, appears to be a pervasive phenomenon leading to the emergence of inter-industry segments. A current example of convergence can be witnessed in the nutraceuticals and functional foods sector, emerging at the boundary between the food and pharmaceutical industries. Not only technologies blur, but there is also a convergence of demand structures: consumers try to satisfy different needs in one transaction. In this context, this paper explores how actors from different industry-specific resource backgrounds can engage in an innovative activity requiring new technological and marketing competences. Given that absorptive capacity is limited by existing competences, this paper asks how organizations with different R&D competences are able to seize opportunities for innovation emerging from convergence. Empirical findings based on primary data collected from 54 R&D projects of a nutraceutical cluster show that there are different approaches of front end decision making: while some firms follow existing processes for front end decision making, others leave existing paths and need partners to fill in gaps already identified at the front end of innovation.
