Última IDENTIFYING IMPLICIT COLLUSION UNDER DECLINING OUTPUT DEMAND AgEcon Weliwita, Ananda; Azzam, Azzeddine M.. The "trigger price" oligopoly model is used to develop a test for oligopolistic as well as oligopsonistic conduct by observing how an industry responds to unexpected declines in output demand. The hypothesis that U.S. beef packers maintain cooperative pricing strategies is rejected. Tipo: Journal Article Palavras-chave: Demand and Price Analysis. Ano: 1996 URL: http://purl.umn.edu/31029 COMPETITIVE BEHAVIOR IN THE FOOD RETAILING INDUSTRY AgEcon Park, Timothy A.; Weliwita, Ananda. We develop a flexible model to examine competitive conditions in the food retailing industry based on the Box-Cox transformation of the demand and industry equilibrium conditions. The impact of key technological and market developments on shifts in the competitive index is examined. Adoption of optical scanning technology was positively related to the market power index but the index was stable and consistent with competitive conditions over the 1982-1992 period.

Ano: 1996 URL: http://purl.umn.edu/16680 SUPPLY RESPONSE IN THE NORTHEASTERN FRESH TOMATO MARKET: COINTEGRATION AND ERROR CORRECTION ANALYSIS AgEcon Weliwita, Ananda; Govindasamy, Ramu. This paper reexamines supply response in the Northeastern fresh tomato market during the 1949-94 period by employing cointegration and error correction technique. It tests whether there has been a long-run equilibrium relationship between Northeastern production and a set of price and nonprice factors that influence it. Findings suggest that wage rate, imports from competing regions, and urban pressure have had significant negative impacts on regional production. The negative relationship between price and production may have resulted from the strong negative effects exerted by the nonprice factors.
