This question can be answered qualitatively keeping in mind what we learned in GDP growth accounting (assuming an aggregate Cobb-Douglas production function). The Inflation Reduction Act (IRA) is a legislation enacted in August 2022 by the U.S. Congress. One of the goals of IRA was to use government subsidies to stimulate private investment in clean energy and consequently increase future national productive capacity. a) Suppose that IRA succeeds. Then, holding employment and total factor productivity constant, explain how an increase in gross private investment in the present (in period t) affects i. the capital stock in the future (at the beginning of period t+1), ii. the growth rate in capital (between t and t + 1), iii. real GDP in the future (over t+1), and iv. the growth rate in real GDP (between t and t+1)
