Need for cognitive closure and information search strategy

The authors investigated whether need for cognitive closure (NFCC) affected one's style of information search (attribute‐based search vs. alternative‐based search) in consumer choice. There has been growing interest in NFCC in marketing and its relationship to consumer information processing. However, no study to date has examined the different information search strategies that consumers employ when they (1) possess different levels of NFCC or (2) are exposed to situations that evoke more or less NFCC. Across two studies where Study 1 measured NFCC while Study 2 manipulated NFCC, the authors commonly found that higher NFCC compared to lower NFCC resulted in (1) a greater preference for the attribute‐based search over the alternative‐based search and (2) a consideration of a smaller amount of information to make a final choice. Implications for consumer information processing and sales strategies are discussed along with future research directions. © 2008 Wiley Periodicals, Inc.     

Radiological findings of human fascioliasis

Fasciola hepatica is a trematode of herbivorous mammals. Humans are accidentally infected by the ingestion of water or raw aquatic vegetables contaminated with the metacercaria. Radiological findings of six patients with fascioliasis (five hepatic fascioliasis, one biliary fascioliasis) were analyzed. The diagnosis was based on serologic testing and/or histopathologic findings of eosinophilic abscess in five patients and identification of the adult worm in one patient. The characteristic radiological features of hepatic fascioliasis were (1) cluster of microabscesses arranged in tract-like fashion (burrow tract), (2) subcapsular location of the hepatic lesions, and (3) very slow evolution of the lesion on follow-up examinations. In biliary fascioliasis, there were multiple conglomerated filling defects in the common bile duct. The authors believe that the demonstration of these features, together with peripheral eosinophilia or eosinophilic aspirate from the hepatic lesion, is very helpful in making the correct diagnosis.     

Are Exports of China,Japan and Korea Diverted in the Major Regional Trading Blocs?

In recent years China, Japan and Korea, the three major economies in East Asia, have been gearing up their efforts to sign free trade agreements with many different regions and countries. One of the main reasons for this is that they fear that with a regionalism movement rising in every corner of the world, their exports are discriminated against and diverted in the trading blocs of other nations. The main purpose of this paper is to investigate whether this is a real fear. We utilise the gravity equation augmented with dummy variables for regional trading blocs in three different specifications. One is the static, standard gravity model to examine the effect of regional blocs on the ‘level’ of exports from these three countries in 2003; the second is the fixed effects and random effects panel models for the period 1993–2003; and the third is the dynamic, partial‐adjustment model to examine the effect of blocs on the ‘changes’ in exports between 1993 and 2003. The results show that trade diversion is observed only for China's exports in EU, EFTA and EAEC, but no diversion effect is observed for Japan's and Korea's exports in any of the major trading blocs. On the other hand, trade creation is observed for exports from China in ASEAN, for exports from Japan in ASEAN, CACM, CARICOM, EAEC, EU and NAFTA, and for exports from Korea in ASEAN, CACM, EAEC and MERCOSUR. Thus, Japan's and Korea's fear of discrimination and trade diversion is ungrounded, while China's fear is grounded only to a limited extent.     

Substitution between U.S. and Canadian Wheat by Class

The imports of hard red winter and durum wheat from Canada has been a source of contention among U.S. wheat growers, due to the likeness between domestic and imported Canadian wheat. This has also been investigated as a source of material injury to the U.S. market. We examine the relative substitution between U.S. and Canadian wheat, by class, by treating wheat as an input in flour production. We find that while U.S. hard red spring wheat and U.S. hard red winter wheat are economic substitutes, there is limited price substitution between U.S. and Canadian durum and U.S. and Canadian hard red spring wheat. Quality differences from the millers’ perspective may be the reason driving the import demand for hard red spring and durum wheat from Canada. Les importations de blé de force rouge d'hiver et de blé dur en provenance du Canada sont une source de conflit chez les producteurs de blé des États‐Unis, en raison de la ressemblance entre le blé produit aux États‐Unis et le blé importé du Canada. Ce point, jugé comme une source de préjudice important au marchéétatsunien, a également fait l'objet d'une enquête. Nous avons examiné la substitution relative du bléétatsunien et canadien, selon la classe, en traitant le blé comme un intrant dans la production de farine. Nos résultats ont indiqué que, bien que le blé de force roux de printemps et le blé de force rouge d'hiver soient des substituts économiques, la substitution en raison du prix demeure limitée entre le blé dur étatsunien et canadien et entre le blé de force roux de printemps étatsunien et canadien. Les différences de qualité perçues par les meuniers pourraient être la raison qui stimule la demande d'importation de blé de force roux du printemps et de blé dur en provenance du Canada.     

Impacts of regulating greenhouse gas emissions on livestock trade flows

Policies regulating greenhouse gas (GHG) emissions are expected to create a significant burden on emitting industries as well as final consumers, which can lead to a strong influence on international trade flows of commodities. This study examines whether the regulation of GHG emissions affects livestock trade flows. A commodity‐specific gravity model approach is employed to estimate and test the impact of regulating GHG emissions on livestock trade flows. The results show that regulation of GHG emissions has a negative effect on livestock trade flows from countries restricting GHG emissions to countries without GHG restriction, from restricting countries to restricting countries, and unrestricting countries to restricting countries.     

Role of International Trade in Chinese Economic Development

This study examines the interdependency between Chinese agricultural and industrial sectors. A dual economic model was developed to investigate the relationship between the two sectors and factors affecting Chinese economic development. The study reveals that inputs, such as labor, are important to Chinese economic development. Capital investment contributed to the growth of the Chinese industrial sector. The results also suggest that foreign trade has made a significant contribution to economic development. Growth of the Chinese agricultural sector seems to depend on industrial growth, but growth of the industrial sector does not rely on agricultural growth.     

Dynamic Effects of Patent Policy on Sequential Innovation

When one patented innovation enables another, endogenous delay of the latter has important implications for the economics of patent life and scope, if licensing is negotiated ex post. Optimal patent life may be finite under competition, even if the royalty imposes no deadweight loss and there is no competitive dissipation of rent. Reduced scope of the first patent eliminates delay of costly enabled innovations, whether monopolized or competitive, and a combination of limited scope and infinite life can be optimal. If the second innovation is negotiated ex ante, its patentability can increase or decrease the first innovator's profit, depending on cost and market structure of the second innovation, and patent life.     

Investigation of the effect of secondary market on the diffusion of innovation

In the high-tech product market, the number of hungry adopters, a new type of early adopters who buy new products and sell them soon in the on- or off-line secondary market to seek for the other new products, has been increasing due to the short product life cycle of high-tech products and the low transaction cost on the Internet. This new phenomenon means that it is inappropriate to consider customers only in the primary market as total adopters in innovation diffusion modeling, since purchasers in the secondary market also have a word-of-mouth effect on the remaining non-adopters. To explain this new phenomenon, we modify the basic Bass diffusion model by incorporating the effect of the secondary market and conduct an empirical analysis. As a result, we conclude that the basic Bass model is likely to overestimate sales volume and tends to forecast lagged peak time when there is an effect from the secondary market. This means that applying a diffusion model to high-tech products without considering the secondary market effect would provide an inaccurate market forecast.     

IMPORTER LOYALTY IN THE INTERNATIONAL WHEAT MARKET

Important political and institutional relationships exist between most grain-trading partners. In many cases the purpose of these relationships is to enhance importer loyalty to a particular exporter. This paper tests for loyalty in the world wheat market. Loyalty is measured by repeat purchases. An application of the Markov model is used to analyse loyalty and to explain international trade flows in wheat. Results show that in general the United States has relatively strong import loyalty compared to the other exporters such as Canada and the European Community.     

A generalized Armington trade model: Respecification

Even if the original version of the Armington model is simple and plausible in estimation, the single CES and homotheticity assumptions are too restrictive for practical application and give biased price elasticities. This paper develops a generalized Armington model, which relaxes the single CES and homotheticity restrictions, and includes the Armington model as a special case. The Armington and generalized Armington trade models are applied to the Japanese meat import demand to demonstrate their performance. The empirical results rejected the two assumptions imposed on the Armington model. The generalized Armington model provides an alternative to the restrictive but indispensable Armington model.
