Demand conditions in the market change. So, now the equation system describing (in inverse form) demand and supply in this competitive market is: p = 52 - 0.5 q, p = 2 + 0.1 q. Determine this market's equilibrium quantity q* (in units of the commodity).
S6. Consider a simplified model in which everyone gets electricity either from solar power or from fossil fuels, which are both in relatively inelastic supply. (Ín the case of solar power, think of the required equipment as being in inelastic supply.) The upfront costs of using solar energy are high, so when the price of fossil fuels is low (that is, when few people are using fossil fuels and there is a high demand for solar equipment), the cost of solar can be prohibitive. In contrast, when many individuals are using fossil fuels, the demand for them (and thus the price) is high, whereas the demand (and thus the price) for solar energy is relatively lower. Assume the payoff table for the two types of energy consumers to be as follows: COLUMN Solar Fossil fuels Solar 2,2 3,4 ROW Fossil fuels 4,3 2,2 (a) Describe all possible ESSS of this game in terms of s, the proportion of solar users, and explain why each is either stable or unstable. (b) Suppose there are important economies of…
a) Derive the goods market demand curve in terms of the output (Y) and the exogenousvariables:c0,c1,b0,b1,g0,g1andT. Show your work for full credit. b)Draw the Goods Market Equilibrium. Be sure to label all curves, label the equilibrium point, and label the slope of each curve. c)Solve for the equilibrium output (Y) in terms of the exogenous variables:c0,c1,b0,b1,g0,g1andT. Show your work for full credit. d)Supposeg1increases, but stillc1+b1+g1<1. Using a graph of the goods market, show how we would represent an increase in the value ofg1on equilibrium output y. Be sure to label all axes, curves, and equilibrium points. e)Suppose instead,c1+b1+g1= 0. Is the equilibrium in the goods market still possible? If so, what is the equilibrium output? You must explain your answer to receive full credit.
Walmart can be viewed as a first mover. Now suppose both Walmart and HEB are considering whether and how to enter a potential market. Market demand is given by the inverse demand function p= 900−q1−q2, where p is the market price margin, q1 is the quantity sold by Walmart and q2is the quantity sold by HEB. To enter the market, a retailer must build a store. Two types of stores can be built: Small and Large. A Small pantry store requires an investment of $50,000, and it allows the retailer to sell as many as 100 units of the goods at zero marginal cost. Alternatively, the retailer can pay $175,000 to construct a Large full-service supermarket that will allow it to sell any number of units at zero marginal cost. *Assume Walmart has built a Large full-service supermarket (i.e.Walmart chooses to build a large full-service supermarket L1 at the first stage). Calculate Walmart's profit for the following cases: a.) HEB chooses not to enter N at the second stage after viewing Walmart’s…
Assume the aggregate demand and supply of a good are given by: Qd(p)=16−p & Qs(p)=3p−4 a.) Where p equals the price of the good. If there are no taxes imposed on the consumption or production of the good, what will be the competitive equilibrium quantity?
a) Suppose demand for good X is given by QD = 900- p/2 where p is the price and QD the quantity demanded. Supply is given by QS = p/4. Suppose 60 TL tax is imposed on each unit ofX that is purchased. What is the burden of the tax? Explain the key factors that determine the incidence of the tax. b) Describe the main differences between partial and general equilibrium analysis in the context of examining tax incidence.

Multiple choice question. As opposed to general equilibrium analysis, partial equilibrium analysis looksa) at an equilibrium and changes to it in a single, isolated market.b) at how changes in all other markets effect a particular market.c) at how equilibrium is determined in all markets simultaneously.d) at either price or quantity movements.
