- If the
equilibrium quantity of semiconductorsdemanded is - Explain how international trade could make it possible for even a small economy to take full advantage of economies of scale, while also benefiting from competition and the variety offered by several producers.

We R' Write currently purchases the wood used to make their pencils, the rubber used to make erasers for their pencils, and the lead for the pencils from other firms. However, We R' Write is considering purchasing these firms so they can personally produce all the components used for making pencils.
As an economist, what would you call the current way We R' Write is acquiring the products needed to make their pencils (purchasing from other firms)?
What benefits and problems could We R' Write have with the current way of doing business?
As an economist, what would you call We R' Write's proposal to purchase the firms that make the pencil components?
What benefits and problems could We R' Write have concerning the purchase of these other firms?
1) The joint cost (in thousands of euros) for two products X and Y can be given by the following formula: C(x, y) = 40 + y^2 + 3x + 2xy + (x^2) y + y^3
where x represents the quantity of product X that is produced and y represents the quantity of product Y produced.
• If 12 units of product X and 20 units of product Y are produced, what are the marginal costs?
• What product line should be expanded in the current level of production?
2) A firm can produce up to 500 units each week. If its average cost function is C(x) = 500/x + 1500 and its total revenue function is given by: R(x) = 1600x − x^2
• What production maximizes profit? What is the maximum profit for that production level?
• What production makes the profit equal to zero? (that point is called the break-even point)
Consider two neighboring island countries called Contente and Dolorium. They each have 4 million labor hours available per week that they can use to produce jeans, corn, or a combination of both. The following table shows the amount of jeans or corn that can be produced using 1 hour of labor.

- Suppose that initially Denali uses 1 million hours of labor per week to produce pistachios and 3 million hours per week to produce chinos, while Sequoia uses 3 million hours of labor per week to produce pistachios and 1 million hours per week to produce chinos. As a result, Sequoia produces 24 million pounds of pistachios and 32 million pairs of chinos, and Denali produces 12 million pounds of pistachios and 72 million pairs of chinos. Assume there are no other countries willing to engage in trade, so, in the absence of trade between these two countries, each country consumes the amount of pistachios and chinos it produces. Sequoia's opportunity cost of producing 1 pound of pistachios is4 pairs of chinos, and Denali's opportunity cost of producing 1 pound of pistachios is2 pairs of chinos. Therefore,Sequoia has a comparative advantage in the production of pistachios, andDenali has a comparative advantage in the production of chinos.

Group of answer choices Intra-industry trade brings competition and diverse products to markets where economies of scale would otherwise promote fewer firms and fewer product options Intra-industry trade reduces competition and product variety in markets where economies of scale would otherwise promote competition and diverse products. As average total cost increases, intra-industry trade increases As average total cost decreases, intra-industry trade decreases.arrow_forwardMost firms in the apparel and footwear industries choose to outsource production to countries where labor is abundant (primarily, Southeast Asia and the Caribbean)long dash—but those firms do not integrate with their suppliers there.
