Market Structure in the Residential Real Estate Brokerage Market

This study provides empirical evidence regarding brokerage firm concentration in a local market multiple listing service setting over the year 1992-1995. To evaluate the level of brokerage firm concentration in this market, Gini Coefficients, Herfindahl-Hirschman Indices and Concentration Ratios for each year of the study period are calculated. Our results indicate that for firms responsible for listing properties, firm concentration has not varied substantially over the four-year study period. However, for those firms that were responsible for actually selling properties, firm concentration has decreased over the study period. This finding tends to indicate that the MLS now provides greater exposure to a wide variety of sales firms, therefore leading to a higher level of competition with a lower level of concentration for selling firms in this local market.

An Input-output Model of the North Central Region of Texas

The primary objective was to estimate the structural interrelationships of the North Central Texas Economy in 1967. This region is a thirty-one county area with a 1970 population of 3,064,560. Economic interdependencies were estimated by Input-Output analysis. The regional Input-Output Model consists of transactions, input coefficients, and interdependence coefficients tables. Monetary values of transactions among 108 processing sectors, of sales to final demand (including regional household consumption and exports), and of purchases in addition to local interindustry transactions (including household payments and imports) are estimated in the transactions table from primary and secondary data. Input coefficients estimate the value of inputs required from each processing sector to produce one dollar of output for a sector. Interdependence coefficients show the total required expansion of output in all regional processing sectors as a result of a dollar of output for a sector
