LONG-RUN MARGINAL COST: The change in the long-run total cost of producing a good or service resulting from a change in the quantity of output produced. Like all marginals, long-run marginal cost is the increment in the corresponding total. What's most notable about long-run marginal cost, however, is that we are operating in the long run. Unlike the short run, in which at least one input is fixed, there are no fixed inputs in the long run. As such, there is only variable cost. This means that long-run marginal cost is the result of changes in the cost of all inputs.

NET-EXPORT EFFECT

A change in aggregate expenditures on real production, especially net exports from the foreign sector, that results because a change in the price level alters the relative prices of exports and imports. The net-export effect, also termed the international-substitution effect, is one of three effects underlying the negative slope of the aggregate demand curve associated with a movement along the aggregate demand curve and a change in aggregate expenditures. The other two are real-balance effect and interest-rate effect. The net-export effect is somewhat analogous to the substitution effect underlying the negative slope of the market demand curve.
