This paper investigates spatial variations in product prices using an exhaustive micro dataset on fish transactions. The data record all transactions between vessels and wholesalers that occur on local fish markets in France during the year 2007. Spatial disparities in fish prices are sizable,...

Hedonic price regressions have become a standard tool to study how prices of commodity goods are related to quality attributes. In this paper, we extend the traditional price specification by incorporating three sources of unobserved heterogeneity related to sellers, buyers, and matches between...

Many small island states have developed economies that are strongly dependent on tuna fisheries. Consequently, they are vulnerable to the socio-economic effects of climate change and variability, processes that are known to impact upon tuna fisheries distribution and productivity. The aim of...

This paper evaluates the degree of integration between the world market and the major European marketplaces of frozen and canned tuna through both vertical and horizontal price relationships. Spatial linkages are investigated horizontally in order to estimate the connection between the European...

Depuis Aristote et Saint Thomas d'Aquin jusqu'aux économistes classiques et contemporains, l'homme n'a cessé de s'interroger sur la notion de "juste prix". Les premiers auteurs l'associaient à une égalité dans l'échange, une réciprocité de services, davantage qu'à un rapport marchand....

The article analyses risk perception in shellfish farming as well as farmers' willingness to rely on coverage mechanisms. Factor and econometric analyses (logit and ordered multinomial logit models) have shown that a number of socio-economic factors specific to farmers and their businesses...

La tempête Xynthia a marqué les esprits par sa violence et par l'ampleur des dégâts et des pertes humaines occasionnés. Dans cet article, nous nous intéressons à l'impact de la tempête Xynthia sur la conchyliculture. Après avoir dressé le bilan des conséquences économiques sur cette...

The firm's management in production is a critical, but unobserved input. Within a panel data framework, the firm's management and firm effects have to date been conflated. Exploiting variability in the managerial dimension, this paper identifies the firm's management from firm and time effects...

We consider a production economy where commodities are partitioned into irreproducible factors and reproducible goods, and the production technologies have constant returns to scale. We examine the geometry of the efficient frontier of the global production set and derive theorems of...

We propose a multivariate extension of a well-known characterization by S. Kusuoka of regular and coherent risk measures as maximal correlation functionals. This involves an extension of the notion of comonotonicity to random vectors through generalized quantile functions. Moreover, we propose...
