MARGINAL PROPENSITY TO INVEST: The proportion of each additional dollar of national income that is used for investment expenditures. Or alternatively, this is the change in investment expenditures due to a change in national income. Abbreviated MPI, the marginal propensity to invest is the slope of the investment line used in the analysis of Keynesian economics. As such, it also plays a role in the slope of the aggregate expenditure line and the multiplier effect.

PROTECTIONISM

The view that the domestic sector of an economy, its consumers, and its producers should be protected from imports by imposing barriers to foreign trade. This is based on the notion that imports are detrimental to the economy and to its citizens. Protectionism is intended to secure domestic jobs, increase domestic wages, promote domestic production, and create a balance of trade surplus. It usually takes the form of tariffs, import quotas, and assorted non-tariff regulatory barriers.
