Procurement of logistics services and sustainable development in Europe: Fields of activity and empirical results

This paper strives to answer the general question; how far purchasers of logistics services take into account aspects of sustainable development. Modeled on the German Sustainable Development Strategy, which is based on the EU Sustainable Development plan, five fields of activity are defined: the reduction of transport intensity and emission, the reduction of land use, the choice of carrier under consideration of sustainable aspects, the permanent improvement of working conditions, and the enhancement of qualified employment. Then, propositions for purchasing companies of logistics services are developed, which contribute to safeguard ecological as well as social sustainability. In order to conduct an explorative study, a questionnaire was sent to 750 purchase and logistics managers. It was found that purchasing companies place high value on ecological and social aspects. But the perceived importance is not associated with purchasing companies' own contributions to logistics service providers' sustainable activities. Additionally, it was seen that purchasing companies exert only a minor influence on logistics service providers regarding ecologically and socially sustainable actions. A fundamental precondition for a sustainably oriented procurement of logistics services can be seen in the purchasing companies' awareness of the need for integrating sustainable aspects in economic decisions.     

Taxpayer resistance,guarantee uncertainty,and housing finance subsidies

In the absence of external guarantees, a private firm's debt trades in the market at rates reflective of its private default risk. Not all firms go it alone, however. There are entities, government-sponsored enterprises (GSEs), whose debt obligations enjoy federal guarantees. Federal guarantees affect housing finance indirectly in that they tend to enhance the creditworthiness of the debt obligations of the housing intermediary which lessens the debtholder's exposure to default. The market investor then becomes a willing buyer of GSE debt at a lower (subsidized) rate as a result of the government guarantee.Due to the fact that the subsidy rests on the presumption that the GSE debt will be bailed out by the government it can be seen that the subsidy in turn rests upon the presumption by the GSE debtholder that the taxpayers will honor the guarantee in the event of a GSE default. Hence, government subsidies to the housing intermediaries rest not on ongoing government outlays but rather on the confidence that the taxpayers will be willing, if called upon, to cover GSE losses, i.e., the confidence of a bailout.This article analyzes the effects on the GSE subsidy and on the taxpayer, if the debt markets charge for bailout risk. Bailout risk pricing is an economic event. When debtholders seek to protect themselves by pricing for bailout risk, this increases GSE borrowing costs and cuts into both GSE borrowers' subsidies and stockholder earnings. Higher borrowing costs leave the GSE in a weakened condition and increase the ex ante bailout cost to the taxpayer. When bailout risk premiums become priced by the market, it substantially lessens the government's ability to subsidize housing finance or other GSE activities.     

Non-existence of equilibrium in Vickrey, second-price, and English auctions

A simple example shows that equilibria can fail to exist in second price (Vickrey) and English auctions when there are both common and private components to bidders’ valuations and private information is held on both dimensions. The example shows that equilibrium only exists in the extremes of pure private and pure common values, and that existence in standard models is not robust to a slight perturbation.     

The effects of air quality regulations on the location decisions of pollution-intensive manufacturing plants

This research examines the effects of the 1977 Clean Air Act Amendments (CAAA) on the location decisions of pollution-intensive manufacturing plants. We develop a panel data set to analyze plant births of polluting manufacturers over time as a function county-level attainment status of the federal standard for ozone pollution. We find that more stringent county-level environmental regulations impact pollution-intensive capital flows through deterring new plant births. We also find that the impact of stricter regulations varies by pollution-intensity of manufacturers, with results suggesting that federal guidelines have a greater impact on high pollution intensive manufacturers than more moderate polluters.      

The hydroelectricity consumption and economic growth in Asian countries - evidence using an asymmetric cointegration approach

ABSTRACT

This study examines the four commonly tested hypotheses in hydroelectricity consumption – economic growth literature for 12 Asian countries. Our results from a recently developed hidden cointegration technique uncover rich and significant relationships between negative and positive components of the variables under consideration. In particular, we find evidence to support the neutrality hypothesis in five countries (Bangladesh, Indonesia, Pakistan, Philippines, and Thailand), the growth hypothesis in four countries (India, Japan, South Korea and Taiwan), and both growth and conservation hypotheses in three countries (China, Malaysia, and New Zealand). These findings suggest that appropriate economic policies should be elaborated on the basis of the country’s specific hydroelectricity consumption–growth nexus. Finally, our new evidence suggests that the lack of stable relationship between hydroelectricity consumption and economic growth documented in previous studies for some of these countries could be due to the failure to properly account for the nonlinearity property in the data.     

Distinguishing market segments to assess price responsiveness

Economists and marketers have developed theoretical constructs which suggest that effective market segmentation can be used to identify differences in price sensitivity among market theory in the industrial marketing literature by using marketing research to distinguish market segments that are useful in industrial pricing decisions. Both macrosegmentation, using characteristics of customers (that is, end-use and usage level), as well as microsegmentation (using behavioral variables) were utilized in a survey of natural gas customers to determine if segments of the industrial market differ in price sensitivity.     

Economies of scale and trade policy: The median voter model revisited

Why do some political economy models perform so poorly in predicting actual trade policy? Do scale economies provide the missing puzzle to our understanding of the anti-trade bias? By integrating economies of scale in production, this paper theoretically reinstates the median voter model as in Mayer [Mayer, W. (1984). Endogenous tariff formation. The American Economic Review, 74, 970–985] as a suitable political economy model in predicting trade policy. The modified model generates the scope for the anti-trade bias and predicts that sometimes economic, rather than political, considerations may lead to restrictive trade.     

REINVENTING THE WHEEL? AFRICAN COOPERATIVES IN A LIBERALIZED ECONOMIC ENVIRONMENT

ABSTRACT ** :  Cooperative development in Africa can be said to have traversed two main eras: the era of state control and that of liberalization. The first era lasted up to the early 1990s and saw the origin and substantial growth of cooperatives on the continent. During that period, different models of cooperative development were introduced on the continent. We distinguish a unified cooperative model, a social economy model, a social movement model, a producers' model and an indigenous model. But in all cases, cooperatives were engulfed into state politics. However, little is known about the impact of liberalization measures on these models. Our research in 11 African countries reveals that cooperatives in Africa have survived the market forces and continued to grow in number and membership. We see a slow but sure erosion of the unified model and the adoption of a social economy model. Cooperatives in Africa are re-examining their organizational forms and diversifying their activities in response to members' interests and needs.
