The government of Laos has made significant efforts to halt deforestation and promote forest conservation in the Northern Uplands of Laos. However, there is no comprehensive assessment of the initiatives and factors that influence youth involvement in forest resource conservation. Therefore, the objective of this study was to identify sustainable f...

In this study, we investigated the influence of climatic factors on rice yields across different growth stages and predicted future rice yields in different regions of South Korea. The results revealed that although climatic factors had limited effects during the vegetative growth stage, significant correlations were observed during the reproductiv...

The government of Laos has made significant efforts to halt deforestation and promote forest conservation in the Northern Uplands of Laos. However, there is no comprehensive assessment of the initiatives and factors that influence youth involvement in forest resource conservation. Our goal was to find sustainable forest management practices and und...

There has been a steady increase in the consumption of Korean beef in recent years, with the per capita consumption of beef reaching a record high in 2022. The domestic beef market provides consumers with more choices, so traditional methods of demand analysis that rely on whole beef products are likely to become less useful. Employing the multiple...

This study examined income mobility of farm household and investigated the determinants of the income mobility in Korea. For the analysis this study used Farm Household Economy Survey (2003-2020), which is surveyed by Statistics Korea, and employed transition matrix and probit specification. According to empirical results, the income mobility of fa...

Consumer demand for meat is constantly growing and changing in Korea, and a number of studies have examined the determinants of meat demand, especially hanwoo beef. In addition to domestic Korean beef, consumers encounter various alternatives such as the U.S. and Australian beef in the beef market, and purchase them in consideration of their prefer...

Commercial and regional brewers are increasingly introducing fruit flavoured beers to meet consumers’ preferences. This article uses data collected from online survey targeting a national sample of women aged 20~30s who have been recognized as the primary consumers to elicit preferences for multiple attributes related in fruit flavored beer. We use...

This study estimates consumers’ willingness to pay for several eggs attributes, with primary focus on animal welfare. A nationwide online survey of 1,000 consumers was conducted to determine consumers’ preferences for animal welfare certification and identify perceptions of animal welfare claims and certifications factors affecting consumers’ willi...

This study analyzed factors affecting profit efficiency of rice farms in wet-season lowlands in the Champhone District of Savannakhet Province in the Lao People’s Democratic Republic based on a farmer’s decision to maximize profits. The profit efficiency approach has an advantage in that it provides insights into both inputs and outputs. To analyze...

Bang Kachao, the largest green area in the Bangkok metropolitan area, delivers significant ecosystem services to sustain society free of charge. It is therefore difficult to achieve socially optimal services because of inefficient allocation of resources, over-consumption, and negative externalities resulting from market failures. This study’s purp...

Demand for seafood is continuously growing, while fish resources have been progressively exploited. Many countries treat technological development as a catalyst to improve the productivity of aquaculture and sustainable development of capture fisheries and they support fisheries technological development through government R&D expenditures. This st...

Feeding operations are substantial on livestock farms, besides being potentially expensive. Feeding efficiency has been considered a major influence on profits in the livestock industry. Indeed, feed costs are shown to be the largest single item of production cost in Korea. To promote production and use of domestic forage, the Korean government has...

The paper examines US citizens’ preferences about the notion of multifunctional agriculture using survey data collected by the Ipsos-Observer in 2008. The survey presented a box of information about multifunctional roles of US agriculture to respondents and sought to measure their attitudes and perceptions about various components of multifunctiona...

Given that soy foods possess health-promoting attributes that offer the promise of reducing heart-related chronic diseases, this article employs choice experiments to estimate marginal willingness to pay (WTP) for soy attributes including taste, contents of soy protein, and health claim. Random parameter logit (RPL) models were estimated in conside...

This paper analyzes price differentials among conventional, cage-free, organic, and Omega-3 eggs using retail scanner data from two regional markets and the United States as a whole. Results reveal significant premiums attributable to cage-free (a 57% premium on average) and organic (an 85% premium on average). However, significant variation exists...

For over the last thirty years the multinomial logit model has been the standard in choice modeling. Development in econometrics and computational algorithms has led to the increasing tendency to opt for more flexible models able to depict more realistically choice behavior. This study compares three discrete choice models, the standard multinomial...

Although experimental studies have reported a wide array of other-regarding behavior, the pervasiveness of such behavior in the field is an open question. Using a stated-preference experiment, we first estimate people’s preferences, when purchasing food products, for the distribution of benefits accruing to participants in the food supply chain. Al...

We compare the ability of three preference elicitation methods (hypothetical choices, nonhypothetical choices, and nonhypothetical rankings) and three discrete-choice econometric models (the multinomial logit [MNL], the independent availability logit [IAL], and the random parameter logit [RPL]) to predict actual retail shopping behavior in three di...

Recent findings from behavioral economics suggest people are concerned about the fairness and inequality in simple distribution experiments. This study sought to determine whether such considerations also carry over to food choice. A conjoint-type experiment was developed and administered to a random sample of the U.S. population via mail survey to...

We compare the ability of three preference elicitation methods (hypothetical choices, non-hypothetical choices, and non-hypothetical rankings) and three discrete-choice econometric models (the multinomial logit, the independent availability logit, and the random parameter logit) to predict actual retail shopping behavior in three different product...
