Other things equal, a decrease in the cost of capital would be associated with an upward shift of the investment function and, hence, with a rise in aggregate expenditures

Falling output, in the short run, could be due to:

A. an increase in short-run aggregate supply. B. a reduction in aggregate demand. C. an increase in long-run aggregate supply. D. an increase in aggregate demand.

Recall the Application about determining the optimal level of methane abatement to answer the following question(s).Recall the Application. The EPA has estimated the cost of methane recovery at different recovery levels. Given those costs, the efficient level of methane recovery:

A. depends on the estimate of the marginal benefit of methane recovery. B. is zero because the costs exceed the benefits. C. will increase if scientists determine that methane is not as harmful as it is currently thought to be. D. will include only recovery from landfills and coal mines, but not from natural gas distribution.
