TRADE DEFICIT: Formally termed a balance of trade deficit, a condition in which a nation's imports are greater than exports. In other words, a country is buying more stuff for foreigners than foreigners are buying from domestic producers. A trade deficit is usually thought to be bad for a country. For this reason, some countries seek to reduce their trade deficit by(1) establishing trade barriers on imports, (2) reducing the exchange rate (termed devaluation) such that exports are less expensive and imports more expensive, or (3) invading foreign countries with sizable armies.

TOTAL COST AND MARGINAL COST: A mathematical connection between marginal cost and total cost stating that marginal cost IS the slope of the total cost curve. This relation between total cost and marginal cost is also seen with total variable cost. The slope of the total variable cost curve is marginal cost, as well. The relation between total cost and marginal cost is but another in the long line of applications of the totalmarginal relation. Total Cost and Marginal Cost 

  The slope of the total cost curve (and total variable cost curve) is marginal cost. As such, if the total cost curve has a positive slope (that is, is upward sloping), then marginal cost is positive. Moreover, if the total cost curve has a positive and increasingly steeper slope, then the marginal cost is positive and rising. If the total cost curve has a positive and increasingly flatter slope, then the marginal cost is positive but falling. This particular totalmarginal relation applies to both total cost and total variable cost. Because not only is marginal cost the slope of the total cost curve, it is also the slope of the total variable cost curve. The reason is that any changes in total cost resulting from changing output is matched by changes in total variable cost. This occurs because total fixed cost is FIXED. This twopaneled graph for the production of Wacky Willy Stuffed Amigos (those cute and cuddly armadillos and rattlesnakes) visually illustrates the connection between total cost and marginal cost. For the first few quantities of output (Stuffed Amigos), total cost in the top panel is positive AND the slope of the total cost curve decreasesit becomes flatter. This corresponds with a positive and decreasing marginal cost in the bottom panel up to 4 Stuffed Amigos. For the next several quantities of Stuffed Amigos output, the slope of the total cost curve becomes increasingly steeper. This corresponds to an increasing marginal cost in the bottom panel. The prime conclusion is the key role played by the law of diminishing marginal returns in the slope of both the marginal cost curve and the total cost curve.  The Ushape of the marginal cost curve is a direct reflection of first increasing marginal returns, as marginal cost falls to a minimum, then decreasing marginal returns and the onset of the law of diminishing marginal returns as marginal cost rises.
 However, because the marginal cost curve is a plot of the slope of the total cost curve, then the shape of the total cost curve also reflects the law of diminishing marginal returns. The flattening slope of the total cost curve for small quantities of output is due to increasing marginal returns. Then the onset of the law of diminishing marginal returns causes the total cost curve to become increasingly steeper.
While this diagram relates marginal cost and total cost, the same story applies to the relation between marginal cost and total variable cost. Marginal cost is also the slope of the total variable cost curve. As such, the shape of the total variable cost curve is also a reflection of increasing, then decreasing marginal returns.
