- Consider an economy of four sectors, Agriculture, Energy, Manufacturing, and Transportation. Agriculture sector sells 12% of its output to Energy, 35% to Manufacturing, 25% to Transportation and retains the rest. Energy sector sells 30% of its output to Agriculture, 30% to Manufacturing, 15% to Transportation and retains the rest. Manufacturing sector sells 30% of its output to Agriculture, 27% to Energy, and retains the rest. Transportation sector sells 20% of its output to Agriculture, 10% to Energy, 30% to Manufacturing and retains the rest. a. Construct the exchange table for this economy. b. Write down the system of linear equation that leads to prices at which each sector’s income matches its expenses, and solve these equations by Gaussian method to find these prices.You have been tasked with developing a research report based on an economy of your choice anywhere in the world.

A. as workers produce, their wages will rise and they will have more disposable income for consumption, leading to a rise in GDP per Capita. B.The amount a worker can produce and that worker's income are exactly equal so that these numbers stay the same. C.The amount a worker can pproduce and that workers's income are not always exactly equal, so these numbers may differ. D. An aggregate production function describes the input of an entire economy based on various outputs such as capital, labor and technology.
