Changes in demographic and socioeconomic characteristics have contributed to an increase away-from-home food consumption. Although consumers are increasingly demanding higher quality food, unbalanced nutrition intakes health issues such as obesity remain prominent predicaments. This paper investigates the relationship between frequency of having Food Away From Home (FAFH), balanced dietary intakes, (controlling for covariates) among Korean adults aged 19 64. Whether there exists a linear...
The fluctuation of vegetable prices in recent years underscores the need to identify contributing factors and develop effective policies. In order examine affecting prices, this paper uses a structural model constructed by demand, supply, import, export functions decompose price variance, also performs numerical simulation generalize results. We studied Korean market, selected cabbage, radish, dried red pepper, garlic, onion as research objects. results indicates that variability domestic...
As income is rising and urbanization progressing, the consumption of meat dairy products increasing, especially in developing countries. However, increasing livestock production leads to challenges that need be addressed, such as yielding environmental pollution causing climate change. Due these circumstances, importance sustainable farming has been highlighted order effectively utilize natural resources protect environment. We analyzed consumers’ preference willingness pay for milk, one...
This paper investigates the asymmetry of price transmission in marketing chain shipping points and terminal markets for fresh fruits western United States. To preserve distinct patterns related to product perishability, we use data constructed at a fine time scale representing vertical linked with shipments. Using decade weekly data, estimate autoregressive distributed lag model derive dynamic multiplier effects responses. Our results indicate that adjustments are closely characteristics,...
Coupled with green house effects, the urban heat island is occurring more frequently, and thus becoming a serious social problem. In order to elicit policy implications, current study assesses economic values on island-mitigating functions of forest through choice experiments. The analytical results suggest that metropolitan city residents’ utility can be increased by raising size life zone forests which comprised street trees, parks in residential regions, small school zones. derived...
This paper elicits consumers' preferences associated with attributes of a very popular food product in Asia: red ginseng concentrate. The results choice experiment suggest that an asymmetric information problem can cause and valuation for concentrate to be significantly influenced by objective about the product's attributes. imply while result differential changes different attributes, it increase willingness pay also discuss important policy marketing implications from study.
Abstract The vegetable market experiences significant price fluctuations due to the complex interplay of trend, cyclical, seasonal, and irregular factors. This study takes Korean green onions as an example employs Christiano–Fitzgerald filter CensusX‐13 seasonal adjustment methods decompose its into four components: fluctuations. To estimate volatility forecast future prices, we apply ARMA‐GARCH model use various statistical measures assess prediction accuracy. empirical results demonstrate...
Abstract This article uses an equilibrium displacement model (EDM) to assess the impact of a change in trade policy Korean infant formula market that is assumed be oligopolistic. Domestic oligopolists compete for homogenous good with importing firms who enjoy same level power as domestic producers. Within EDM framework, we investigate how adjusts new response external shock improves access foreign goods. Our empirical work consists two steps. We first econometrically estimate demand...
This study contributes to the empirical industrial organization literature by deriving and estimating equation containing parameter for bargaining power an indicator of competition between suppliers. We specify a reduced form price equation, which is composed minimum specified in milk marketing orders upper bound regional raw markets United States. Estimation results indicate that relative dairy cooperatives setting prices small compared bottlers. find differential has contributed raise bargained
Purpose – The purpose of this paper is to assess the effects Economic Cooperation Framework Agreement (ECFA) on grouper fish markets in Taiwan and mainland China. Design/methodology/approach A stochastic simulation model developed such a way that oligopoly or monopoly power exporters plays role for having different impacts ECFA. Findings Taiwan's sector benefits considerably from implementation ECFA tariff reductions. Export Taiwanese China overall gross revenue farmers are simulated...
Abstract We investigate revealed political market power reflected in the pattern of price discrimination by end use that is hallmark U.S. milk marketing orders. show prices would maximize producer profits, if producers operated a cartel with monopoly regional market, far above actual government‐set differentials between used for fluid products and manufactured products. The consistent welfare weights relative to consumers are small compared yield maximum profits.
