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.     

Why and How Combining Strong and Weak Ties within a Single Interorganizational R&D Collaboration Outperforms Other Collaboration Structures

The purpose of this paper is to demonstrate why and how an ambidextrous interorganizational R&D collaboration outperforms other collaboration structures in the creation of innovation. This research effort contributes to a growing stream of research in social network theory suggesting that the contradictory theories of the strength of weak ties and weak network structures on the one hand and the theory of strong ties and closed network structures on the other have a mutually reinforcing effect on innovation outcomes if combined rather than considered separately. An in‐depth exploratory single case study approach within an innovatively organized national R&D collaboration allowed giving further evidence for such a superior innovation performance and for this research to contribute to theory by demonstrating why and how such a combination may lead to higher innovation output and how this effect can be actively reinforced. It is suggested that the combination of strong and weak ties should occur at the individual rather than at the project or firm level. The authors distinguish between the additive effects of the respective innovation benefits of strong and weak ties, a positive interaction effect in the portfolio of dyadic ties of an individual and a second multilevel interaction effect of weak ties embedded in the ambidextrous network structure. Referring to previous empirical findings, intellectual property regulation and structural interdependency between network members showed a higher impact than trust with regard to leveraging weak ties and are important sources for achieving the multilevel interaction effect. Managerial implications of this research are that a large network will outperform several smaller, independent networks given that the right structure and processes are in place. Direct implications for the architecture of an ambidextrous R&D collaboration are discussed, and a framework for a new form of technology R&D collaboration called “semi‐open organization” is presented, which places itself between the extremes of traditional R&D in closed organizations and completely “open innovation” approaches.     

The Dodd‐Frank Wall Street Reform and Consumer Protection Act: Accomplishments and Limitations*

The Dodd‐Frank Wall Street Reform and Consumer Protection Act of 2010 is widely described as the most ambitious and far‐reaching overhaul of financial regulation in the United States since the 1930s. Together with other regulatory reforms introduced by regulatory agencies globally, the Act aims to put an end to the too‐big‐to‐fail problem and is expected to alter the structure of financial markets in profound ways. This article provides an overall assessment of the Act in three different ways: first, in light of first economic principles, or how theory suggests we should regulate the financial sector, given the systemic risk externality each financial firm imposes on other firms and the rest of the economy; second, from a comparative perspective that views the proposed reforms in relation to those undertaken in the 1930s following the Great Depression; and, finally, in the form of an assessment of how the proposed reforms would have fared in preventing and dealing with the crisis of 2007–2009 had they been in place at the time. The article also highlights key areas that are left wholly or partly unaddressed by the Dodd‐Frank Act—notably, the pricing of explicit and implicit government guarantees; dealing with inevitable opportunities for the financial sector to engage in regulatory arbitrage; and containing the systemic risk arising from collections of small institutions and markets such as money market funds and repo contracts.     

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.     

Chinese competition: intra-industry and intra-firm adaptation

Review of World Economics - This paper quantifies how a small and open economy adapts and thereby shapes to what extent it is exposed to competition from China on the world market. Starting from...
