Assessing Time-Varying Oligopoly and Oligopsony Power in the U.S. Paper Industry AgEcon
Mei, Bin; Sun, Changyou.
The U.S. paper industry has become increasingly concentrated and therefore been suspected of imperfect competition. In this study, the new empirical industrial organization approach is employed to measure the degree of oligopoly and oligopsony power in the U.S. paper industry simultaneously. The model is estimated by iterative three-stage least squares using annual data from 1955 to 2003. The results reveal that there has been significant oligopoly and oligopsony power in the U.S. paper industry, and the oligopoly power has been consistently lower than the oligopsony power.

Dynamic Assessment of Bertrand Oligopsony in the U.S. Cattle Procurement Market AgEcon
Ji, In Bae; Chung, Chanjin.
The new empirical industrial organization approach with the Bertrand model is employed to measure the oligopsony market power in the U.S. cattle procurement market. The assumption of price competition (Bertrand model) based on the nature of cattle production such as cattle cycle and seasonality is used and compared to quantity competition (Cournot model). The empirical results show that the oligopsony market power exists in the U.S. cattle procurement market. The cattle cycle and seasonality affect the oligopsony market power and the cattle cycle causes the change of market power. However, concentration has a negative effect on the oligopsony market power.

Dynamic Assessment of Oligopoly, Oligopsony Power, and Cost Efficiency using the New Empirical Industrial Organization in the U.S. Beef Packing Industry AgEcon
Ji, In Bae; Chung, Chanjin.
In this paper, the new empirical industrial organization approach with a dynamic model is simultaneously employed to measure the degree of oligopoly, oligopsony power, and cost efficiency in the U.S. beef packing industry. The oligopsony power is estimated with two effects: cash cattle procurement market power and captive supply market power. The model is estimated by the Generalized Method of Moments using monthly data from 1990 to 2006. The empirical results reveal the presence of market power in both the beef retail market and the cattle procurement market in the sample period. The captive supply is a source of oligopsony market power, but the effect is considerably small. The oligopsony market power is greater and less stable than oligopoly market...

Is There Market Power in the French Comte Cheese Market? AgEcon
Merel, Pierre R..
An NEIO approach is used to measure seller market power in the French Comté cheese market, characterised by government-approved supply control. The estimation is performed on quarterly data at the wholesale stage over the period 1985-2005. Three different elasticity shifters are included in the demand specification, and the supply equation accounts for the existence of the European dairy quota policy. The market power estimate is small and statistically insignificant. Monopoly is rejected, as well as weak forms of Cournot oligopoly. Results appear to be robust to the choice of functional form, and suggest little effect of the supply control scheme on consumer prices.
Tipo: Conference Paper or Presentation Palavras-chave: Supply control; NEIO; Protected designation of origin; Marketing.
