Instrumental variables (IV) estimation of a demand equation using time series data is shown to produce a weighted average derivative of heterogeneous potential demand functions. This result adapts recent work on the causal interpretation of two-stage least squares estimates to the simultaneous...

"The Fulton Fish Market started out in 1822 as a general food market like others in the city because it was located in a residential neighborhood.

Fish play a major role in the Bangladesh food system. Fish production, processing and marketing are major source of incomes for many households, and fish consumption accounts for a significant share of protein consumption in the Bangladeshi diet. Moreover, fish production and consumption are...

This article develops and implements a Real Option approach to value renewable natural resources in the case of Marine Fisheries. The model includes two sources of uncertainty: the resource biomass and the price of fish, and it can be used by fisheries to optimally adapt their harvesting...

This study aims to give brief information about exporting activities in Oman, where it tend to present the available information in simple methods depending on the diagrams to illustrate the information, and to investigate the main problem behind the improper managing of the exporting system,...

Fish farming has been carried out for centuries and is essentially fairly simple. It becomes a challenge when it is used for commerce. This brochure highlights the major complications associated with intensive and cost-efficient fish farming. In Armenia, there are a number of pro and cons to its...

The importance of fish size for price per kilo is studied using an inverse demand approach. Prices per kilo in different size categories of the same species differ significantly. This means that the average price for a species may change due to e.g., high-grading, growth overfishing or a...
