Suppose the government reduces the corporate income tax rate. This will increase the return to firms for investing, which should $\boxed{investment \ and \ cause \ an \ increase \ in \ capital \ in \ the \ long \ run.}$ As a result of the corporate tax cut, the long-run aggregate supply curve will $\boxed{shift \ to \ the \ right}$. The new long-run equilibrium will be A. anywhere along the aggregate demand curve. B. where the aggregate demand curve intersects the original long-run aggregate supply curve. C. where the aggregate demand curve intersects the new long-run aggregate supply curve. D. anywhere along the original long-run aggregate supply curve. The long-run impact of a reduction in corporate tax rates would be A. an increase in long-run potential output while creating additional upward movements in prices. B. a decrease in long-run potential output while actually reducing inflation. C. an decrease in long-run potential output while creating additional upward movements in prices. D. an increase in long-run potential output while actually reducing inflation.

Choose all that are true. ? Individualism and collectivism are not mutually exclusive; that is, they can coexist within a person of any culture. ? Individualistic societies seek solutions where there are clear-cut winners and losers. ? The most relevant feature of individualism, as defined in the majority of the studies, is valuing personal independence. ? Individualism is linked to a sense of duty to group, interdependence, harmony, and working with the group.
