Multiple Inference and Market Integration: An Application to Swedish Fish Markets

This paper, in contrast to earlier studies, tests market integration using a methodology that accounts for the multiplicity problem inherent in testing several time series. This method minimises the risk of finding spurious evidence of market integration. We examine market integration among 12 fish species in Sweden by applying cointegration tests, which identify market integration for two separate clusters of species. Furthermore, we find that the Law of One Price holds for 6 of the 12 species considered.     

湖南省江湖鱼类资源及其保护研究

湖南省江湖水面广阔,鱼类栖息条件优越,鱼类资源丰富,全省共有鱼类 170 种和亚种,分属于 10 目 24 科 93 属,其中以鲤形目鲤科占绝对优势,鲶目的鲍科次之。全省江湖主要经济鱼类多达 40 余种,淡水鱼业生产在全国占有重要地位。近几十年来,湖南江湖鱼类资源由于捕捞过度、水质污染、水面缩小等原因而急剧衰退,亟待加强保护。

Product Differentiation with Credence Attributes and Private Labels: The Case of Whitefish in UK Supermarkets

The retail market for seafood is dynamic with substantial competition both amongst retailers and between private labels and national brands. New product attributes are added in attempts to differentiate products and to attract consumers. Credence attributes, in particular those related to eco‐labels and fishing method, have become more common. But little is known about how these and other credence attributes are valued in the retail market. In addition, little is known about price differences between private labels. To estimate the value of these attributes, weekly in‐store observations of selected frozen whitefish products were conducted in seven UK retail chains in the city of Glasgow. An estimated hedonic model shows a substantial price premium for fishing method (line‐caught), a premium for both home (Scottish) and non‐home country of origin (Icelandic) and a premium for the Marine Stewardship Council eco‐label. An uncertified eco‐label owned by a large seafood manufacturer leads to reduced price. The study also reveals substantial price differences between private labels for whitefish. The results contribute new insights regarding opportunities for differentiation by credence attributes which may lead to more sustainable and effective resource use along the value chain for frozen whitefish.     

Wholesale Demand for Fish in Greece

Inverse demand systems explain price variations as functions of quantity variations. This article presents a dynamic inverse almost ideal demand system (AIDS) model based on recent developments on cointegration techniques and error correction model. The case of fish landed at Greek seaports appears to suit this model well. The results indicate that the underlying distance function is homothetic whereas the own-quantity flexibilities suggest that the responses of price to own-quantity changes are inelastic. Finally, the results of cross-quantity uncompensated flexibilities suggest that the substitution possibilities among fish grades are rather limited. The Allais interaction intensities verified the substitutability among fish grades as well.

Explaining the Role of Perceived Risk,Knowledge, Price,and Cost in Dry Fish Consumption Within the Theory of Planned Behavior

ABSTRACT

The general purpose of this study is to explore the influence of perceived risk, knowledge, price, and cost of dry fish consumption in Bangladesh using the general framework from the theory of planned behavior (TPB). The field experiments were performed in Bangladesh with a convenience sample of 558 respondents. Multiple regression analysis was used to investigate the relationship among perceived risk, knowledge, price, and cost and TPB constructs. The findings showed that attitude, norms, and procedural knowledge emerge as the key determinants of intention, whereas intention, attitude, norms, and perceived risk have effects on the dry fish consumption frequency. Perceived behavioral control, price, and cost had no significant effect on intention and consumption behavior. The proposed TPB and the extended model both fit the data well and proved the expectations of this study in a promising way. The study found that people are more concerned about potential long-term risk to their family and others. Therefore, management attention should focus on reducing risks which consumers may face through producing safe and hazard-free dry fish.
