In this paper, we discuss the effect of refunding environmental charges.

This paper compares consumer preferences for immunocastration versus surgical castration and no castration using willingness- to-pay estimates from a choice experiment.

Results suggest that consumers place a higher value on pork from immunocastrated pigs than pork from surgically castrated pigs. In contrast, consumers reveal negative valuations of pork from intact boars as compared to pork from surgical castrates. We also show how a binary heteroskedastic logit model can be used to accommodate a larger variance for later choice sets within a choice experiment.

An optimal first-best road charge should not only be differentiated with respect to factors that affect the direct external environmental and time costs from the road-user himself.

Indirect effects, such as the fact that others’ cars will be more polluting when congestion increases, should also be taken into account.

The choice of domestic fuel is a matter of great concern for households and policy makers in India. This paper investigates the demand for domestic fuels when households face four choices: Fuelwood, Coal, Kerosene and LPG.

We use firm-level data to study the adoption of Environmental Management Practices
(EMPs) in the most polluting industrial sectors in Bulgaria, Hungary, Lithuania, Poland,
Romania, and Slovakia during the 1990 – 1998 period when these countries were in a
transition away from a centrally planned economy.

In two experiments on the choice of consumer goods, the estimated marginal willingness to pay for food is found to be lower in the survey version with cheap talk.

Our test can be seen as a test of hypothetical bias. This implies that we cannot reject the hypothesis of a hypothetical bias for marginal WTP in choice experiments.

Community forest plantations are a common intervention in developing countries. We use household and remote sensing data from Orissa, India, to estimate welfare effects of community forest plantations, in terms of the value of decreased collection times plantations afford users.

The proportion of money sent, which is typically assumed to reflect trust, decreased significantly as the stake
size was increased in a trust game conducted in rural Bangladesh.

Nevertheless, even with very large stakes, most senders and receivers sent substantial fractions.

The most important Namibian linefish species, the silver
kob Argyrosomus inodorus, is currently heavily
exploited, and in order to ensure its survival catch
restrictions are being introduced. However, kob are
exploited both by recreational anglers and by commercial
vessels, and it is important to examine the economics
of these fisheries in order to determine where catch
restrictions will do the least harm to the economy.

This paper reports the results of a stated preference survey in the highlands of Ethiopia where the farmers are given a choice between an agricultural extension package and a local public - representing two major developing strategies. The study finds that a majority of people prefers the public good.
