The Mexican economy underwent a process of growth and transformation in the twentieth century, which was confirmed by the indexes and figures that economists use to chart the rate of growth, even allowing for possible inaccuracies in these figures. This volume of six essays makes readily available to English-speaking readers a selection of significant contributions by outstanding Mexican economists dealing with the mid-twentieth-century growth of the Mexican economy. Enrique Pérez López provides an overview of the development of the gross national product in the economy and the structural changes that were imperative if basic social goals were to be implemented and the optimal adjustments to changing world conditions effected. Ernesto Fernández Hurtado discusses the process of accommodation and cooperation between the public and the private sectors that has contributed significantly to economic growth, stressing particularly the role of agriculture. Mario Ramón Beteta describes central bank policy and the functioning of the Central Bank, showing how control over credit and the banking system assures stability and accelerating growth through its credit rationing. Alfredo Navarrete R. traces the sources of domestic savings that have provided 90 percent of the capital employed in the economy since the Revolution, and Ifigenia M. de Navarrete demonstrates that rapid economic growth has not resulted in a more equitable distribution of income. Victor Urquidi stresses the balanced growth, achieved by allocating public capital formation to basic infrastructure, that has helped develop agriculture as well as industry, and indicates the nature of the structural change that must occur if the economy is to expand rapidly. In his introduction Tom E. Davis compares growth in Mexico with developments during the same period in Chile and Argentina. The country reached its midcentury standard of living after fifty years of drastic social and political changes under a constitution that altered the system and the concept of private property and the role of the state. These new concepts brought about changes in the structure of production and social relationships, together with a rise to new cultural, technical, and moral levels. These changes, in turn, placed Mexico in a new position with new problems. A question that must be answered is whether the economic goals of the future require a reappraisal of social relationships and of the ways of administering and utilizing the country’s resources and potential productivity.
