Breeding can result in more output per unit of inputs as well as improved quality of outputs. A genetic-based technical change component is introduced into the Malmquist index, and productivity growth due to genetic and nongenetic factors is estimated for Icelandic dairy farms with quality...

Fishers in quota-regulated fisheries find it to their advantage to discard less valuable fish at sea to increase the value of their catch. A theoretical model describing the high-grading behavior of fishers is presented, and an empirical model is derived as well as a testing strategy to test for...

Increasing public concerns about health risks associated with dietary intakes of cholesterol are expected to have significant impacts on the demand for foods with high fat content. This paper investigates how information about cholesterol, as measured by two newly constructed indices based on...

The price of a product depends on its characteristics and will vary in dynamic markets. The model describes a processing firm that bids in an auction for a heterogeneous and perishable input. The reduced form of this model is estimated as an expanded random parameter model that combines a...

This article is concerned with efficient estimation of characteristics demand. We derive and estimate an inverse input demand system for quality characteristics by using 172,946 observations over 881 trading days in the Icelandic fish auctions. An improved estimation method based on an expanded...

A model with nonlinear discarding costs is developed for a fishery with an individual transferable quota (ITQ) program. The model shows that limited hold capacity and ITQs provide incentives to discard fish. The model is applied to the Icelandic ITQ-regulated cod fishery to test for highgrading...

A theoretical model with nonlinear discarding costs is constructed to describe highgrading in a fishery with an Individual Transferable Quota (ITQ) program. The model shows that ITQs provide incentives to discard fish when the hold capacity of the vessel is nonbinding. An empirical model is...
