There is a large body of literature in economics examining the US meat market, but few studies have focused on the US goat meat market. This study, as a catch-up effort, provides an estimate of the demand for goat meat and assesses the impact of driving factors in the US goat meat market. The data for this study were collected in 11 southern states and specifically elicit the demand and consumer preferences in this non-conventional market. Four econometric models are fitted to examine the multiple layers of the demand, including the current, the potential, the latent, and the seasonal demand. Findings indicate a substantial demand for goat meat with great growth potential, driven by demographic factors and food safety concerns. Ethnic groups and the aged comprise the current niches for goat meat, and the preferences for healthy and safe meat will define the market in the future. 展开更多

In the 1980s, China’s auto market saw three dramatic fluctuations. Since the beginning of the 1990s, the market, as a whole, has become calm and stable without any major changes, though it has never evaded occasional rises and fails. The pattern of demand on the market has been generally set and clear, and has begun to grow steadily. In view of the present situation, two major categories of vehicles—office-use and business or service use cars and trucks—have long been in demand on the market, almost dominat- 展开更多

This paper calls attention to the demand resource market in Korea which opened in 2008 to reduce customers' consumption at critical times and, at the same time, secure the load that can be shut down. In Korea, the demand resource market is operated by either forward market or spot market. The discussion here is limited to the operations of the demand resource spot market. As the demand response program has matured in the smart grid environment, KPX (Korea Power Exchange) will shortly complete the development of the real-time demand resource trading system, taking into account an integrated dispatch system. 展开更多

Consumers and developers are the market transaction subjects which drive the development of building energy efficiency market. High energy prices, unreasonable heating system, information asymmetry of building energy suppress demand of energy efficiency construction; high technical risk and construction cost, nonstandard market restrict the supply of energy efficiency construction. To promote the development of building energy efficiency, we must set up effective incentive policies for both sides of the market transaction, improve the supervisory system, promote the technological progress, build the information sharing platform, so as to achieve the purpose of cultivating and improving the building energy efficiency market system, regulating the behavior of supply and demand subject, building the mutually beneficial and cooperative partnership, and realizing the balance of interests. 展开更多

Despite the significant annual consumption of honey in Saudi Arabia, information gaps remain with regard to the marketing and market structure of honey along the value chain. This study analyzed the major factors that influenced the consumption, expenditure patterns, and demand of honey in Saudi Arabia. This study forecasted the near-future expected market demands for honey in Saudi Arabia by collecting and analyzing the primary data using questionnaires. A total of 331 respondents from representative regions and large cities were randomly selected and interviewed. The data were analyzed using qualitative and quantitative methods as well as appropriate econometric models. Respondents characterized honey quality using organoleptic words, and these characterizations varied based on the relative significance of perception parameters. Taste, aroma, physical state, and color had aggregated average scores of 4.58, 4.44, 3.54, and 3.28, respectively. In addition to the above parameters, honey source, brand name, and confidence in the producers influenced its perceived quality. The major outlets for honey in Saudi Arabia included producers, specialized honey stores, and auction markets in major cities during the harvesting seasons. Medication, food, and sweetening were the major motivations for buying honey in the Saudi market, with aggregate scores of 4.52, 3.71, and 1.52, respectively. Significant honey price variations were observed within and among different honeys and packaging volumes;this finding might be due to factors such as botanical and geographical origins, package volume size economics (i.e., bulk purchases), honey variety blending, brand names, and producer policies. The average price of locally produced honey was approximately $73 per kg, which is 10 times more than the average price of honey in the US and the EU. The estimated consumption/income elasticity was 0.27. These results suggest that honey is a basic commodity in Saudi Arabia. Based on econometric model forecasts, the Saudi market demand for honey is expected to reach approximately 29,784 tons in 2025. 展开更多
