Offer curve 1. A curve showing, for a two-good model, the quantity of one good that a country will export (or "offer") for each quantity of the other that it imports. Also called a reciprocal demand curve, it is convenient for showing exports and imports in the same curve and can be used for analyzing tariffs and other changes. [Origin]
2. Offer curves are also used to represent the supplies and demands of individual consumers in a barter economy and to illustrate equilibrium and its properties in that context.

2. For a country, this usually means the combination of different goods (and services) that it can produce that is worth the most at world prices, perhaps adjusted for any externalities.
Optimal tariff The level of a tariff that maximizes a country's welfare. In a nondistorted small open economy, the optimal tariff is zero. In a large country it is positive, due to its effect on the terms of trade.
Optimal tariff argument An argument in favor of levying a tariff in order to improve the terms of trade. The argument is valid only in a large country, and then only if other countries do not retaliate by raising tariffs themselves. Even then, this is a beggar thy neighbor policy, since it lowers welfare abroad. See Johnson (1953/54).
Optimal tax 1. Given a constraint of a minimum amount of revenue that a taxation must raise, a system of optimal taxes will minimize the distortion that they cause.
2. In the presence of an externality, the optimal tax (or subsidy) is that which will internalize its effects so that optimal decisions will be made.
Optimum 1. The best. Usually refers to a most preferred choice by consumers subject to a budget constraint, a profit maximizing choice by firms or industry subject to a technological constraint, or in general equilibrium, a complete allocation of factors and goods that in some sense maximizes welfare.

Original sin In the context of financial problems of developing and emerging economies, this refers to their difficulty in borrowing abroad in their own currencies.
