there are two firms A and B. Suppose A wants to produce more. In order to judge whether this decision of increasing production is gainful or not A has to conjecture how B will react to this decision. This is conjectural variation. The nature of the equilibrium changes with change in conjectural variation pattern. In oligopoly firms have several decision variables. It can decide on quantity‚ price‚ quality of product‚ advertisement‚ investments‚ timing of entry in the market etc. Existence of so many

(Rock paper scissors‚ matching pennies to name a couple) Does this mean that we have no solution concept for these types of games? Not by a long shot! () Mixed Strategy Nash Equilibrium May 22‚ 2012

Once some products are formed the reverse reaction can take place to reform the reactants. In a closed system the concentrations of all the reactants and products will eventually become constant. Such a system is said to be in a state of dynamic equilibrium. The forward and reverse reactions continue to occur‚ but at equilibrium the

Market Equilibration Process Paper Market equilibrium is the point in which industry offers goods at the price consumers will consume without creating a shortage or a surplus of goods. Shortages drive up the cost of goods while surpluses drive the cost of goods down‚ finding the balance in the process is market equilibrium. The concept is derived from combining equilibrium price and equilibrium quantity to yield the equilibrium of a specific market. Changes in the determinants of demand

Problem: For the reaction H2(g) + I2(g) ↔ 2 HI(g) At equilibrium‚ the concentrations are found to be [H2] = 0.106 M [I2] = 0.035 M [HI] = 1.29 M What is the equilibrium constant of this reaction? Solution The equilibrium constant (K) for the chemical equation aA + bB ↔ cC + dD can be expressed by the concentrations of A‚B‚C and D at equilibrium by the equation K = [C]c[D]d/[A]a[B]b For this equation‚ there is no dD so it is left out of the equation. K = [C]c/[A]a[B]b
