2. This chapter argues that saving and spending behavior depend in part on wealth, but our model does not incorporate this. Consider following model of a very simple economy: 10 + 0.75Y + 0.04W C I100 W 1000 = (a) What are the equilibrium levels of GDP, consumption, and saving? (b) Suppose wealth increases 50% to 1500, Recalculate the equilibrium levels of Y,C, and S (c) What impact does wealth accumulation have on GDP?

This chapter argues that saving and spending behavior depend in part on wealth (accumulated savings and inheritance), but our simple model does not incorporate this effect. Consider the following model of a simple economy: C = 50 + 0.8Y + 0.1W I= 200 W=500 Y= C + I S = Y−C When wealth = 500, what is GDP When wealth = 500, what is consumption When wealth = 500, what is savings
