Microeconomic theory develops demand and supply curves to determine the market equilibrium for commodity exchange. The demand and supply functions are the result of consumers utilities and producers production functions for different product combinations. The interaction is a game-theoretic approach to determine the quantity and prices with which goods and services are traded. Economic theory w...

We consider Cournot models of competition, where market participants choose the quantities they demand or supply. We study the loss of aggregate surplus due to the exercise of market power in Cournot competition, for both oligopsony and oligopoly models. We observe that efficiency loss is generally arbitrarily high in Cournot games, but also prove bounds on efficiency loss in several cases of i...

the main purpose of this study is to determine welfare impacts of trade liberalization on maize market. for this purpose, we used from time series data for the period 1961/2009 and estimated domestic supply, domestic demand and import demand for maize. results of estimation showed that price elasticity of supply and demand is 0.32 and -0.25, respectively. then, by means of these elasticities, w...

To investigate the dynamics of tissue oxygen demand and supply during brain functions, we simultaneously recorded Po(2) and local cerebral blood flow (LCBF) with an oxygen microelectrode and laser Doppler flowmetry, respectively, in rat somatosensory cortex. Electrical hindlimb stimuli were applied for 1, 2, and 5 s to vary the duration of evoked cerebral metabolic rate of oxygen (CMR(O(2))). T...
