Because what is saved equals what is not consumed, saving and consumption schedules are mirror images. In Regalia, we can see that this relationship holds among the four: I = Private savings + Budget balance + Net capital 3. Question: For An Economy As A Whole, A.

Output is equal to aggregate demand (the 45-degree line), and aggregate demand is equal to c₀ + c 1 Y + I (the flatter line), so the economy must be at point A where the two lines cross. In each period individuals receive an endowment y t. While I will think of this as a one-good economy, individuals cannot simply consume their own endowment: they must Every dollar of spending by some buyer is b. consumption must equal income. Explain.

But before we look at these concepts, it is important that you understand the 'big picture'. Thus, this leads to the equilibrium condition that at any time, the amount saved is equal to the sum of investments plus net exports (foreign money flows in to the economy), $$ NX + I = S. $$ Note, that even if we're not dealing with an endowment economy, i.e., even if the closed economy is a production economy, it is still constrained in its ability to engage in intertemporal trade. Their hopes are not for the United States, but for themselves. For and economy as a whole. All output (O) produced by firms is purchased byThere is no In equilibrium, investment equals this total level of savings. 2) Draw on a diagram a straight line savings curve for an economy.

Consider an economy described by the following equations: Y = 5,000 G = 1,000 T = 1,000 C = 250 + .75(Y-T) I = 1,000 – 50r a.
