of good 1 is better off trading whenever the exchange ratio,[lambda], is greater than or equal to the individual's fixedmarginal rate of technical substitution, i.e., [lambda] [greater than][f'.sub.2]/[f'.sub.1]. When exchange costs vary with thevolume of trade, however, the marginal condition for trade becomes[lambda] [greater than] (1 +[alpha][f'.sub.1])([f'.sub.2]/[f'.sub.1]). [3] The effect of marginal exchange costs is illustrated in Figure 5.The point marked C is the same as that in Figure 4; namely, it is theoptimal point assuming that the exchange costs are fixed. D denotes theoptimum when exchange costs vary with the volume of trade. The effect ofvariable trade costs is to reduce the effective exchange rate for agiven exchange ratio, [lambda]. The gains from trade are smaller thanwhen exchange costs are fixed and there is a corresponding reduction inthe volume of trade. [4] All other things being the same, the volume oftrade falls from [T.sub.2] to [T.sub.3]. The trade optimum, for a given[lambda], is pushed closer to the autarkic no-trade optimum, which againis denoted by A. If the exchange costs are sufficiently high, theautarkic optimum will dominate the trade optimum for a given [lambda] . Costly trade not only reduces the gains from trade, but moreimportantly, Nike Free 5.0+ Mens Hyper Blue Black Tint Volt it increases the minimum exchange ratio that is requiredfor the individual to benefit from trade. Define the reservationexchange ratio, rer, to be the minimum exchange ratio required for anindividual to acquire the same level of utility that would be acquiredunder autarky. If exchange is costless, rer is simply anindividual's marginal rate of technical substitution. Figure 6shows rer for three assumptions about exchange costs: There is no costof exchange, i.e., [alpha] = 0, and two cases where exchange costs arepositive, [alpha] = [beta] Nike Free 5.0+ Womens Bright Citrus Violet Force Barely Orange [greater than] 0 and [alpha] = [beta]',[beta]' [greater than] [beta]. Figure 6 illustrates that the higherthe exchange cost, the larger is rer, i.e., the more of good 2 that anindividual who specializes in the production of good 1 must get tocompensate for the cost of trade. Trade is advantageous only when theterms of trade are sufficiently favorable adj.1. Advantageous; helpful: favorable winds.2. Encouraging; propitious: a favorable diagnosis.3. , i.e., [lambda] issufficiently large t o compensate for the cost of trade. All of the above conclusions were predicated on the assumption thatthe particular person concentrates on your generation involving very good 1.
