Increased consumption of vegetables may reduce obesity and the prevalence of cardiac diseases and cancer. Norwegians consume less vegetables than nutrition experts recommend and the per capita consumption is lower than in most European countries. To investigate the causes of low consumption, a...

The high and rapidly rising adult obesity rates in the United States, United Kingdom, Australia and New Zealand are associated with major health risks, including cardiovascular disease, diabetes, stroke, and some forms of cancer; large health care costs; and premature deaths annually. For...

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...

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...

We use panel data from two experiments conducted five months a part to investigatethe stability of individual preferences and aggregate demand for five types of fish. Even though the bids in the two experiments are positively correlated, they clearly suggest that the individual preferences are...

Bulgaria's transition to a market economy has coincided with a large increase in wage inequality. Given the emphasis on wage leveling in pre-transition Bulgaria, the rise in wage inequality may be due to managers rewarding more productive workers; or it may be the result of rewarding...

CONTEXT: The prevalence of overweight (OW) among children in the United States has increased during the last three decades, but prevalence measures fail to reveal the extent to which OW children exceed the OW threshold. OBJECTIVE: To measure the amount by which OW children exceed the OW...

This paper considers alternate measures of overweight in the U.S. that are sensitive to changes in the body-mass index (BMI) distribution, more robust to measurement error and continuous in the body-mass index (BMI) at the overweight threshold. The measures suggest that standard prevalence rates...

Essentially all empirical questions that are addressed with sample data require estimates of sampling variance. The econometrics and statistics literatures show that these estimates depend critically on the design of the sample. The sample for the U.S. Current Population Survey (CPS), which...
