The change was publicized as a way to increase the ability for missionaries to serve. At the time, missionaries paid for all their expenses in their country of service. The recession during the Carter presidency pushed inflation higher and the exchange rate lower. This sudden increase in costs together with already high costs of living in Europe and other industrialized nations resulted in a steady decline in the number of missionaries able to pay for two full years of service. The shortening of the required service time from 24 to 18 months cut off this decline in numbers, leveling out in the period following the reinstatement. For those in foreign missions, this was barely enough time to learn a more difficult language and difficulty with language was reported.
