Development of a Network-location-model for the Economic Optimization of Local Heating Systems in Urban Chile

Cogeneration of heat and electricity is an important pillar of energy and climate policy. To plan the production and distribution system of combined heat and power (CHP) systems for residential heating, suitable methods for decision support are needed. For a comprehensive feasibility analysis, the integration of the location and capacity planning of the power plants, the choice of customers, and the network planning of the heating network into one optimization model are necessary. Thus, we develop an optimization model for electricity generation and heat supply. This mixed integer linear program (MILP) is based on graph theory for network flow problems. We apply the network location model for the optimization of district heating systems in the City of Osorno in Chile, which exhibits the “checkerboard layout” typically found in many South American cities. The network location model can support the strategic planning of investments in renewable energy projects because it permits the analysis of changing energy prices, calculation of break-even prices for heat and electricity, and estimation of greenhouse gas emission savings.     

Do financial conglomerates create or destroy economic value?

This paper investigates whether functional diversification is value-enhancing or value-destroying in the financial services sector, broadly defined. Based on a U.S. dataset comprising approximately 4060 observations covering the period 1985–2004, we report a substantial and persistent conglomerate discount among financial intermediaries. Our results suggest that it is diversification that causes the discount, and not that troubled firms diversify into other more promising areas. In addition, the discount applies to all financial services activity-areas with the exception of investment banking and is stable over different combinations of financial activity-areas with the exception of commercial banking units combined with insurance companies and/or investment banking activities.     

Co-determination and working time accounts in the German finance industry

This article examines the workings of co-determination in the German finance industry through two case studies examining the introduction of working time accounts. It is shown that the accounts posed important new challenges for employees and works councillors that represented variants of long-existing negotiations around working time issues. The problems were clear and similar in both cases, giving rise to complaints to councillors, though not to managers. Councillors’ responses differed in the two companies. In one, they successfully re-negotiated the agreement under which the accounts had been introduced. In the other, they did not succeed in doing so. The differences between the two representative bodies are analysed to reflect on a theory of employee representative influence.     

Do corporate codes of ethics reflect issues of societal transformation? Western German and Slovak companies compared

Can differences in corporate codes of ethics arise from the specific situation of transformation in Slovakia in contrast to the stable context of the firms in Western Germany? This paper compares codes of ethics of large‐scale enterprises in both countries in terms of ethical issues addressed. It demonstrates that codes of ethics of the Slovak companies mirror the specific transformational circumstances in the country. Compared with Western Germany the codes of these firms include multiple ethical issues, meaning that they experience a broader range of relevant ethical problems. Furthermore, their codes are internally oriented, in terms of the ethical issues raised most often; they put more emphasis on committing employees, managers and shareholders/owners to the firm. Based on the differences discovered, it is proposed that negative experiences within the past process of transformation and in part the socialist heritage are the main reasons for differences between the two samples.     

The new EEC Merger Control System

On September 21st, 1990 the EEC Merger Control System became effective. The author discusses three problems that have arisen in the European debate on establishing a supra-national merger control:

Competition policy in the EEC

Article 2 of the Treaty of Rome describes the task of the European Community as to encourage stability and growth “by establishing a Common Market and by progressively approximating the economic policies of Member States”.     

Environmental policy and development

This study promotes the understanding of the link between development, environment and international economic relations. It suggests that the growth effects of environmental management may tend to serve as an equalizer, helping to redress the imbalance in real income levels between developed and developing economies.     

Efforts to fill the information gap

Businessmen all over Europe as well as in North America and in other countries have to be Increasingly concerned with international taxation. Therefore the International Bureau of Fiscal Documentation is gaining In importance.     

Individual choice or collective action? Exploring consumer motives for participating in alternative food networks

Alternative food networks (AFNs) are growing in number and relevance in Germany. Those networks include new models of production and distribution, such as food cooperatives (FoodCoops), self‐harvest gardens or community‐supported agriculture (CSA) schemes. AFNs, as an alternative to conventional food supply systems, are characterized by a close producer‐consumer interaction. They are typically located within urban or peri‐urban areas. The study aims to identify the rationale and motivation of urban residents in participating in AFNs and developing a consumer typology. We also assess whether AFNs potentially lead to collective action with societal impact. Therefore, we conducted a qualitative content analysis based on 18 interviews with members of existing AFN projects in three German metropolitan regions. Our results revealed that the willingness of urban consumers to participate in AFNs is driven by a broad range of motives. They include personal desire for high‐quality food (in terms of taste or freshness) and health reasons, but also political or environmental motives (opposition to conventional agriculture or short transport distances). Furthermore, consumers often want to support a certain farmer and his/her philosophy or they appreciate the community‐building aspect. Three different consumer types were derived from the motive combinations. Many consumers communicated a sense of belonging to a societal movement, however, our study revealed a lack of organization and collective action. Although AFNs can influence the consumption patterns of individuals, their potential to induce social change and to challenge traditional models of consumption in the near future does not appear to be high.
