THE basic question to which this paper is addressed is "What is the importance of distance in determining the pattern of Western European trade?"The importance of distance in the pattern of trade has, of course, always been recognized.The assumption of "no transport costs," which has always been necessary in expositions of theories of international trade, is a recognition of the fact that transport costs, that is, the costs of covering distance, exist and are significant; so that abstraction from them has to be made quite explicitly in order to analyze other elements such as factor endowments.' 0 0 t 0 0 0 "inCq 0 e oo HO ~, "d0 80 8 00 0 * .. 99"o 'A-.

rFHIS paper is a summary account of pros ductivity trends since the turn of the century in the American economy, by major segments and industries. Different rates of productivity change in the various industries have significantly altered relative unit costs and prices of products, rates of output, and the distribution of resources by industry. At the national level, productivity growth has been of paramount importance in raising levels of living, in strengthening potential national security, and in the provision for future economic growth. Differences among nations in levels and rates of change in productivity are fundamental measures of comparative economic performance and play a crucial role in the competition among nations and groups of nations. The more we can learn of economic growth generally, and of productivity changes in particular, the better equipped we are to survive the competition and to enjoy continued advances in our planes of living.

R ECENT discussion of future farm output requirements ' have stressed heavily the important role which technological progress is expected to play in meeting the projected output requirements. This is as true of the studies which have emphasized the transitory nature of present food surpluses 2 as of the studies which point to continuation of the present pressure of food supplies on population. I In spite of this emphasis on the importance of technological change, these studies have generally failed to make explicit the relationship between technological progress and changes in factor input requirements other than labor inputs. This failure seems to stem from use of an analytical scheme which fails to distinguish between technological change and change in labor productivity, thus confusing the contributions to farm output made by technological change and increased nonlabor inputs.4 In this paper, I shall attempt (a) to outline an analytical scheme which distinguishes between the contributions of technological change and increased nonlabor inputs, (b) to present a set of alternative technological change and factor input models for American agriculture which will illustrate the possible consequences of alternative rates of technological change on certain aggregate input categories during the next quarter century, and (c) to discuss some questions of agricultural policy stemming from the close relationship between technological change and input requirements.
