Assume that there are two countries, Argentina and Brazil, each producing wheat and wine from capital and labor. Suppose that Argentina has abundant capital and scarce labor when compared to Brazil; that wheat is capital intensive relative to wine; and that the other factor-proportion assumptions apply. a. Using production possibility frontiers, and indifference curves for Argentina and Brazil, illustrate and explain the movement of both countries to the free-trade equilibrium pattern of production, consumption, trade and the gains from trade for the two countries. That is, explain the sequence of the argument as to how mutually beneficial trade between the two countries is possible. b. Given the above trade between the two countries, explain the trade effects on product prices, factor prices, and factor incomes. Why do these effects occur

Net income and owner's equity for four businesses four different proprietorships, jupiter, mars, saturn, and venus, show the same balance sheet data at the beginning and end of a year. these data, exclusive of the amount of owner's equity, are summarized as follows: total assets total liabilities beginning of the year $550,000 $215,000 end of the year 844,000 320,000 on the basis of the preceding data and the following additional information for the year, determine the net income (or loss) of each company for the year. (hint: first determine the amount of increase or decrease in owner's equity during the year.) jupiter: the owner had made no additional investments in the business and had made no withdrawals from the business. mars: the owner had made no additional investments in the business but had withdrawn $36,000. saturn: the owner had made an additional investment of $60,000 but had made no withdrawals. venus: the owner had made an additional investment of $60,000 and had withdrawn $36,000. jupiter net income $ mars net income $ saturn net income $ venus net income $
