DETECTING DIFFUSION PROPERTIES OF SECTORS IN THE MEXICAN ECONOMY, 2012
There are several different methods to identify key sectors of an economy using input-output data. From direct and total linkages to network centrality measures, one may choose one or the other according to the research question at hand. In this paper we identify the strategic sectors according to their role in diffusing the effects of shocks. We use input-output data to compute global centralities and propose a diffusion measure. Results for the Mexican economy show that there are a few sectors that generate a high aggregate effect and that diffuse this effect to a wider part of the economy. These sectors are highly central and are connected to central sectors that help diffuse the effect. The diffusion measure we propose, together with the aggregate effect, and centralities of sectors, allows us to identify those strategic sectors. This is useful for designing an economic policy that aims at maximizing the reach of a stimulus.

La medida de difusion, el efecto agregado y las medidas de centralidad permitieron identificar estos sectores estrategicos, lo cual es util para disenar politicas economicas que tengan como objetivo maximizar el alcance de un estimulo.
期刊介绍:
It is a specialized journal, bilingual (Spanish and English), plural and critical, which accepts and publishes scientific research articles in national and international economy. It is considered a public good that belongs to the University and society. Its vocation is to analyze the evolution of the theoretical and practical economics. In its pages the paradigms of economics, history of economic thought, the theories and debates about economic policy and its consequences, the diagnosis of the Mexican economy, the economic development of Latin America and the problems spread the world economy in general. It is a journal that does not discriminate plural none paradigm; theoretical orientation is unorthodox for epistemological reasons, not ideological preferences.
