The paper studies the degree of international price dispersion for 300 individual goods and services between cities of three country groups over 1999 and 2013, focusing on the role of oil prices in generating deviations from the law of one price. We find that while oil prices did not contribute to the trend in cross-country price dispersion, it does account for within-country price dispersion. Once the oil price effect is subtracted out, the remaining price dispersion between U.S. cities no longer exhibits a noticeable upward trend. If oil prices increase transportation costs, they should increase the deviations from the law of one price, raising price dispersion. Our findings indicate that this effect is more pronounced within a country, while factors such as elasticity of substitution and other trade barriers are likely to matter more in price dispersion across borders. We view our results as complementary to those that emphasize the role of time-varying factors in accounting for price dispersion.

This article studied on price dispersion of food market in Kwangju. Both item and market basket price dispersion were surveyed, and this price dispersion was compared with the perceptive price dispersion. This survey was conducted from April. 8.1992 to 22. On findings, price dispersion is very big in item and market basket. Most Consumers' perception was inaccurate and typically underestimated. This findings suggest that consumers are victims of contributors to informally imperfect markets.

Infomediary, playing an important role in e-commerce, provides refined a product information and the price dispersion of product. This paper use the elaboration likelihood model to explain how level of involvement with a product moderates the impact of price dispersion and product information quality on product attitude. The study produces three major findings : (1) the quality of product information produced by infomediary has a positive effect on consumers' product attitude, (2) For low-involvement consumer, price dispersion of product positively affect consumers' product attitude. For high-involvement consumer, negatively affect, (3) low-involvement consumer are affected by the price dispersion rather than the quality of product information, but high-involvement consumer are affect by price dispersion mainly when the quality of product is low. These finding have implications for on-line infomediaries in terms of how to manage their users.

The purpose of this study is to research the effects of the same brand item sold online at different prices. To that end, the exploratory study is focused on four factors that influence price dispersion online is suggested. First, the products are divided into utilitarian products and hedonic products in line with the product concept, and laptops, washing machines are included in the utility concept products. Also the backpacks and sneakers are included in the hedonic concept products. A total of 400 effective objectives were selected and analyzed for each concept products, 200 objectives. The research analysis revealed that the price dispersion is significant relationship with an average price, the highest price, the lowest price, the year of release, the number of retailers, and the number of reviews in case of the utility concept product. On the contrary, in case of hedonic concept products, average price, highest price, lowest price, year of release, retailer, and reviews and ratings is found to be positively related to price dispersion. Based on these results, theoretical and practical implications are discussed about the influence price dispersion on marketing.

According to the returns of Housing and business cycle over the period 1992 to 2007, it is a measure of the total volatility faced by investors in Housing properties. First, it isn't a distinct difference from business cycle contrary to U.S. Second, the rise of purchase price in total apartments moves up the consumer price index. According to the cross-sectional dispersion of returns and growth in net operating income (NOI) of apartments, industrial, retail and office properties using panel data for U.S. metropolitan areas over the period 1986 to 2002, it is a measure of the total volatility faced by investors in commercial real estate. To the extent that most of that volatility is difficult to diversify, cross-sectional dispersion may be an appropriate measure of risk.

Consumer information influences purchasing behavior; however, less is known about the relationship in the credit market. Credit markets offer consumers a complex array of different products when choosing mortgages. The current study examines whether borrowers search for the very best terms when making major decisions about borrowing money or obtaining credit as well as explores the relation between consumer information seeking and the cost of credit. This study demonstrates the existence of price dispersion between those who made an extensive information seeking and those who did not. When controlling for the proxies of creditworthiness and demographics of the respondents, it is found that those who made a great deal of information seeking tend to have lower mortgage rates than those who made almost no information seeking. This study offers financial educators and policy makers suggestions on how to help consumers make better financial decisions.

The wide range of price found in food market allows consumer reduce the cost of food purchases through comparison shopping into one more stores. Littles known however about how much can be saved by comapring price for a whole market basket of food items. This paper present evidence relating to the comparison shopping through the theories on price is dispersion and show validity constructing methods of food market basket. It is found that the savings of comparison shopping to consumers are likely to be gains in food Markets and three market basket on foods suggest in study found to be validity.

This paper studies the long-run behavior of relative price dispersion among cities in Korea with a special emphasis on heterogeneous transitional patterns of price level dynamics. Formal statistical tests indicate considerable evidence for rejecting the null of relative price level convergence among the majority of cities over the sample period of 1985-2015. The analysis of gravity model suggests that the effect of transportation costs on intercity price level differentials is limited, while other socioeconomic factors, such as income, input factor prices, demographic structure, and housing price growth, play key roles in accounting for persistent regional price level disparities. Individual price levels are found to be better explained by a multiple-component model, and the deviations from PPP may be attributed to distinct stochastic common trends that are characterized by income and demographic structure.

This study attempts to explore urban married women's needs for consumer information contents. In addition, the causality of the needs for consummer information contents and related variables is investigated. Major findings are the following: (1) Respondents' need for information on“the product selection”and “the use and management”of the washing maching or hair dryer is high, while the in need for the information on“the existing brands”is very low. (2) Among several relevent characteristics, respondents' product involvement is strongly related to the needs for consumer information contents. (3) The results of the analysis of casual model from washing maching showed that respondents' age, purchasing experience, perception of the price dispersion and quality difference, self confidence in the product evaluation affect on the need for consumer information contents directly. While respondents' income and education level show a indirect effect. (4) The results of the analysis of causal model from hair dryer showed that respondents' perception of the price dispersion, quality difference and product complexity affect on the need for consumer information contents directly. While respondents' age, purchasing experience, self-confidence in the product evaluation show a indirect effects.
