3. Consider two countries, Australia (A) and Indonesia (I), producing two goods, beef (B) and clothing (C). One unit of labour in Australia is capable of producing 4 units either of clothing or 8 units of beef, while the corresponding productivity coefficients per labour unit in Indonesia are 2 units of clothing and 2 units of beef. a) Determine absolute and comparative advantages and the autarky price ratios, defined as the relative price of ( ). b) Determine autarky real wages in both countries. c) Suppose that the price ratio in free trade becomes = 1.5. Determine real wages in free trade in both countries and show that they are higher in autarky. Compute the limits of the ratio of the Australian wage to the Indonesian wage in free trade
