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.

OPEN ECONOMY

An economy that engages in international trade, especially one that exports goods and services to, and imports goods and services from, other economies that make up its foreign sector. It is "open" in the sense that goods and services flow into and out of the country. The alternative to an open economy is a closed economy, one that does not engage in international trade.

"Motivation is everything. You can do the work of two people, but you can't be two people. Instead, you have to inspire the next guy down the line and get him to inspire his people."
