HEDONIC MODELING OF HOUSING PURCHASE/SALE DENSITY WITH URBAN CHANGE FACTORS

Due to the industrialization in the cities, land needs have appeared in the increasing urban population. These needs have created houses with the accumulate of collective living spaces in the city. It is necessary to determine the supply-demand relationship and value of these real estates with economic importance for smart urban management systems and decision support systems in the market. The value of real estate varies according to the country in which it is located, but in general, it is affected by many factors such as spatial attributes, demographic factors, building factors, economic conditions. Depending on these factors, values and purchase-sale densities of housing also change.In this study, for prediction of housing purchase-sale density, hedonic modeling was realized with 15 features from urban change factors. Urban change factors that affect the purchase/sale of housing such as land use, demographic factors, population density and structural factors have been examined through Geographic Information System (GIS). The hedonic regression method was used for predicting the density of housing purchase/sale. As a result of the modeling, it was found as R2 = 0,85.

The Development and Promotion of Sweet Potato Yoghurt in Ghana: Implications for Sustainable Production and Consumption Policies

This paper analyzes how a newly developed food product (potagurt) with nutritional and health benefits can be promoted in Ghana. We employ the hedonic modeling and contingent valuation methods to estimate monetary values attached to the product’s attributes using 400 consumers in the Ashanti, Eastern, and Greater Accra regions of Ghana. The findings reveal that consumers have positive perceptions on the health and nutritional benefits of the product. Buyers place a higher value on potagurt relative to normal yogurt. The high value attached to potagurt is mainly linked to the health, nutritional, food safety, and quality attributes of the product, as well as perception. Consumers’ socioeconomic factors such as income, educational, and awareness levels also play a significant role in explaining their choice of the product. The practical implication is that the development and promotion of potagurt could stimulate sustainable economic development through better consumer health and improvement in the livelihoods of many players in the sweet potato value chain, especially the producers of potagurt and sweet potato farmers. We conclude that the promotion of the innovative food product could contribute to sustainable production and consumption of sweet potatoes.

International Real Estate Review

This paper considers the information content of Multiple Listing Service (MLS) descriptions and employs a significantly larger data set than previous studies. The analysis first catalogs the most frequently used terms by real estate agents in MLS descriptions. Using hedonic modeling, we estimate the effect of this qualitative information on transaction price and days on the market. Finally, we extend earlier empirical work by utilizing our larger MLS data set to forecast the probability that a house will sell after it is listed. This last contribution further sheds light on the role of qualitative information to infer property condition or circumstances that surround the sale of the property.
