Si América del Norte es un área económica única, las variables deberían converger espontáneamente y, de acuerdo con la teoría del comercio internacional, dado que las tres economías intercambian bienes bajo patrones intraindustriales, la productividad factorial debería ser similar. Este trabajo explora las diferencias en la productividad en los tres países empleando indicadores básicos y el concepto de &#8220;sector verticalmente integrado&#8221;. Los resultados indican que los sectores son crecientemente interdependientes y que la productividad sigue sendas independientes.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Business cycles in the North American countries have converged, while per capita income gaps remain; thus, factoral remunerations must be di&#64256;erent. If North America were a single economic area the relevant variables ought to converge and, according to the pure theory of international trade, factoral productivity should also be similar; particularly when trade between those counties maintain intraindustry patterns. This paper explores the di&#64256;erences in productivity in North America by means of basic indicators and the concept of the &#8220;vertically integrated sector&#8221;. Results indicate that industries are increasingly interdependent and that productivity in each country follows independent paths.]]></p></abstract>
