Income Differentials and Migrations

  • R. Cortés Conde

Abstract

Those who distrust historical statistics are right in doing so, but they would be wrong in rejecting them. In fact, any understanding of statistical information is founded on distrust, and the classical problem of statistics is that of making valid inferences from observations that are known to be poor. To abandon the scraps of quantitative insight into the past merely on the grounds of general suspicion would be as foolish as to regard them as wholly accurate.1

    The problem of the international comparison of purchasing power has been discussed in several works. See, for example, C. Clark, The Conditions of Economic Progress (London: Macmillan, 1940); the study undertaken by ECLA (Economic Commission for Latin America) in 1960–2, and those done for ECIEL (Joint Studies of Latinamerican Economic Integration) carried out by J. Grunwald and J. Carrillo in ‘Integration Económica y Comparaciones de Precios y Valores en la América Latina’ in Estudios Eciel, pp. 65–134, and M.

    P. Nelson, ibid., postulates a positive relationship between migratory flows and past migrations. He states that these are a function of the variables determining the settlement of migrants in the past. He attributes this to information provided by friends and relatives, information that increases the propensity to emigrate.Google Scholar
