10.2 10.2. SINGLE MARKET. Suppose that two countries, initially in autarchy, decide to cre-ate a single market. For simplicity, assume that, in both economies, there is only oneproduct. Demand for this product is given by D₁ = Si (a-pi), (i=1,2), where S, is ameasure of country i's size. Upon the creation of a single market, total demand is givenby the horizontal sum of the two initial demands.Assuming there is free entry and that firms compete a la Cournot, determine theequilibrium number of firms in autarchy and after the completion of the single market.Interpret the results.10.3. CALIFORNIA AND MONTANA. The number of imported automobiles in California isfour times higher than in Montana, in per capita terms. The population of Californianis mainly urban, whereas the population of Montana is mainly rural. How do demo-graphic differences and the model presented in Section 10.1 explain the differences inconsumption patterns?2¹10.4. MARKET SIZE AND MARKET STRUCTURE. In some industries, the number of firmsincreases as market size increases. In other industries, the number of firms seemsremarkably stable despite changes in market size. Discuss.10.5. RETAIL IN SWITZERLAND. Retail in Switzerland is mostly dominated by highlyprofitable cartels. The Swiss authorities anticipate the gradual collapse of these cartelsas the country becomes better integrated with the rest of Europe. OECD, by contrast,hold a more sceptical view, claiming that the collapse of cartels does not necessarilylead to more competitive markets; rather, they add, cartel breakdowns are frequentlyassociated with an increase in concentration. Which prediction seems more reasonable?

The Cournot model is an economic model used to study the behavior of firms in an oligopoly market.…

10.61 The per-store daily customer count (i.e., the mean number of customers in a store in one day) for a nationwide convenience store chain that operates nearly 10,000 stores has been steady, at 900, for some time. To increase the customer count, the chain is considering cutting prices for coffee beverages. The question to be determined is how much to cut prices to increase the daily customer count without reducing the gross margin on coffee sales too much. You decide to carry out an experiment in a sample of 24 stores where customer counts have been running almost exactly at the national average of 900. In 6 of the stores, the price of a small coffee will now be $0.59, in 6 stores the price of a small coffee will now be $0.69, in 6 stores, the price of a small coffee will now be $0.79, and in 6 stores, the price of a small coffee will now be $0.89. After four weeks of selling the coffee at the new price, the daily customer count in the stores was recorded and stored in . At the 0.05…

A company sells three types of products for $20, $15, and $10 per unit. In 1 year, the total revenue for the three products was $2090, which corresponds to the sale of 153 units. The company sold half as many units of the $20 product as units of the $15 product. How many units of each product were sold? How much revenue came from the $20 unit The number of twenty dollar units sold was .The number of fifteen dollar units sold was .The number of ten dollar units sold was .The revenue from the $20 units was
