- the question is attached as photo and answer typed below. please help me show the calculations used to support my answer. the answer Bayesian Nash equilibrium has been refined in this way (BNE). An equilibrium idea relevant to dynamic games with partial knowledge is known as the "Perfect Bayesian Equilibrium" or "PBE" (sequential Bayesian games). The strategies and beliefs that make up a perfect Bayesian equilibrium are as follows: Depending on the information available, a player's strategy will dictate what actions he will do based on that data (on actions taken previously in the game). In some ways, it's like playing through a series of levels in a video game.Players' beliefs in a given information set influence what node in that information set they think the game has reached. Probabilities of the nodes in the data set and the other players' types are often used to calculate the belief's probabilities. From an a priori perspective, every node in the game has a possibility of 1.…Find the concentration ratio of the market whereby the top 4 firms share percentage is as :- 30, 28 , 21 ans 15(Use for questions 1 - 3): Two soap producers, the Fortnum Company and the Maison Company, can stress either newspapers or magazines in their forthcoming advertising campaigns The payoff matrix (profit in millions of dollars) is as follows: Maison Company Stress Magazines Stress Newspapers M, $8M F, S7M M, $9M F, $8M Stress Newspapers Fortnum Company М, $8M F, $9M М, $7M F, $8M Stress Magazines Is there a dominant strategy for each firm?

- The two major scooter companies in India, ABC and XYZ, are competing for a fixed market. If both manufacturers make major model changes in a year, then their percentage market share not change. Also, if they both do not make major model changes, their percentage market share remains constant. If ABC makes a major model change and XYZ does not, then ABC is able to take away a% of the market away from XYZ, and if XYZ makes a major model change ABC does not, XYZ is able to take away b% of the market away from ABC. Express this as a 2 x 2 game and solve for the optimal strategy for each of the companies.(b) Two hotels, Hotel Sandy and Hotel Magda, are competing for a limited number of tourists. The hotels have approval to either expand hotel operations, or add recreational water sports to their offerings. No one hotel has approval do both of these changes. A research company has determined that the following outcomes are likely: If Hotel Sandy expands, and Hotel Magda adds water sports, Hotel Sandy will increase its market share by 1%, and Hotel Magda will increase its market share by 3%. If Hotel Sandy adds water sports, and Hotel Magda expands, Hotel Sandy will decrease its market share by 5%, and Hotel Magda will increase its market share by 2%. If both hotels add water sports, Hotel Sandy will increase its market share by 4%, and Hotel Magda will increase its market share by 5%. If both hotels expand, Hotel Sandy will increase its market share by 2%, and Hotel Magda will decrease its market share by 5%. Given that both hotels employ game theory, what course of action would each…1) Explain in detail the main features of ARCH/GARCH approach and their differences.

- A wholesaler (upstream firm) sells a product to a retailer (downstream firm). Both the wholesaler and the retailer are monopolists. The wholesaler faces a constant marginal cost of $2 and charges the retailer a wholesale price te: The retailer resells the product to final consumers at price P and the wholesale price to is its only cost. The demand for the good is P-12-Q. For your calculations below, assume that both the P and ware measured in dollars per unit. Hint.

Which basic game does it resemble? 0,0 100,300A large company in the communication and publishing industry hs quantified the relationship between the price of one of its products and the demand for this product as Price = 160 -0.01 xDemand for an annual printing of this particular product. The foxed costs per year (ie. per printing) = $4T 000 and the variable cost per unit = $35. What is the maximum profit that can be achieved? What is the unit price at this point of optimal demand? Demand is not expected to be more than 7,000 units per year. The maximum profit that can be achieved is S. (Round to the nearest dolar.) The unit price at the point of optimal demand is S per unit (Round to the nearest cent)
