On economic and social policy

The end of busing of primary and secondary school students has been a major setback for integration of public schools in the USA. The purpose of this paper is not to offer an alternative to busing; regrettably, no obvious alternative stands out. Rather, it is to offer some social, legal and economic background to help the reader consider, and perhaps propose, realistic alternatives that would reduce both racial and economic segregation in our schools and society. The paper is divided into three sections. The first offers background information useful for better understanding and evaluating the end of busing and school resegregation. The second section focuses on an important parallel between racial and economic discrimination. The closing section introduces considerations important for anticipating reactions to, and the costs and benefits of, alternatives to busing for reintegrating schools, as well as several recommendations to which those considerations can be applied.

The effects of entrepreneurial orientation and marketing information on the performance of SMEs

In this study, we investigate the effects of entrepreneurial orientation and marketing information on the performance of small and medium-sized enterprises. We build and test a causal model using data obtained from Singaporean entrepreneurs and find support for most of our hypotheses. The results indicate that entrepreneurial orientation plays an influential role on the acquisition and utilization of marketing information, and also has a direct effect on firm performance. The utilization of information regarding marketing mix decisions (particularly the Promotion and Place elements) positively affects firm performance, and it partially mediates the relationship between entrepreneurial orientation and firm performance. The implications and future research directions are discussed.     

Auditor selection and corporate social responsibility

This study examines the association between the selection of an industry‐specialist auditor and corporate social responsibility (CSR). We find that firms with higher CSR ratings are more likely to hire industry‐specialist auditors (national‐level industry leaders, city‐level industry leaders or joint city‐national industry leaders). Moreover, firms with better CSR performance related to product quality and the environment in controversial industries are found to select non‐specialized auditors. The results suggest that such firms may overinvest in CSR activities associated with the environment and product issues to disguise the sin nature of their manufactured goods, and simultaneously engage low quality auditors perhaps to avoid full disclosure of potential environmental and legal liabilities. Overall, we conclude that CSR is associated with the non‐controversial firms ensuring high quality financial reporting in response to societal expectations, and thus CSR firms in such industries have strong incentives to engage industry‐specialist auditors.     

Antidumping Regulations: Anti‐Competitive and Anti‐Export

In a Bertrand duopoly model, it is shown that an antidumping regulation can be strategically exploited by the home firm to reduce the degree of competition in the home market. The home firm commits not to export to the foreign market which gives the foreign firm a monopoly in its own market. As a result the foreign firm will increase its price allowing the home firm to increase its price and its profits. If the products are sufficiently close substitutes then the higher profits in the home market are large enough to compensate for the loss of profits on exports.     

Energieeffizienznetzwerke – beschleunigte Emissionsminderungen in der mittelständischen Wirtschaft

The reduction of energy-related CO₂ emissions by more efficient enery use in medium sized companies is one of the most profitable options. However, these opportunities are scarcely realised because of many obstacles and market failures. High transaction cost and decision routines play an important role for decision making and procurement of the companies. A network concept being developed in Switzerland and covering an initial consulting of each participating company, targets for the network, regular and moderated meetings of the energy managers for mutual exchange of experiences and a yearly monitoring alleviates many of these obstacles. It doubles the energy efficiency progress relative to the average progress of industry. This network concept can be fully realised by industry itself. Average energy savings per site and year are 100,000 € and average CO₂ emission reduction about 500 t CO₂ per year and site. Assuming a maximum potential of 700 Networks, additional emission reductions of some 10 Mio. t CO₂ seem to be possible in Germany by 2020. A network management system for consulting engineers and moderators allows a minimum performance standard of how to start and operate those efficiency networks.

The effect of the Canada‐US Free Trade Agreement on Canadian multilateral trade liberalization

In this paper show that the Canada‐US Free Trade Agreement (CUSFTA) tariff preferences have triggered a decline in Canadian external tariffs, explaining a two percentage point reduction in the average tariff between 1989 and 1998. Next, we found that industries that generate the least export rent to the US firms experienced deeper tariff cuts in Canada; this result provides evidence of cooperation in trade policies between the US and Canada. Finally, we estimate the effect of the CUSFTA on the intensity of industrial lobbying for trade policy in Canada and find no relationship between preferential trade liberalization and lobbying activity.
