  • Mexican Taxes, and in Particular the Unusual Taxes on the Mining Industry
    EFFECT OF TAXATION ON THE BASE METALS INDUSTRY IN MEXICO by LI BRAR"% Donald Hughes Shaw B.S., Butler University (1953) SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE at the MASSACHUSETTS INSTITUTE OF TECHNOLOGY 1960 Signature of Author Department of Geology & Gephy May 21, 1960 Certified by Thesis Supervisor Accepted by Chairman, Departmental Committee / on Graduate Students April 11, 1960 Professor Philip Franklin Secretary of the Faculty Massachusetts Institute of Technology Cambridge 39, Massachusetts Dear Professor Franklin: In accordance with the requirements for graduation, I herewith submit a thesis entitled "Effect of Taxation on the Base Metals Industry in Mexico". I should like to express my appreciation for the time and assistance granted me by officials from American Smelting and Refining Campany, Anaconda Copper Company, and American Metals Climax Company. I should also like to thank Professor Roland Parks, Associate Professor of Mineral Industries, M.I.T., and Professor Victor Andrews, Assistant Professor of Finance, M.I.T., for their suggestions and assistance, both in research and in pre- paring the final draft of this thesis. Sincerely yours, Donald H. Shaw Effect of Taxation on the Base Metals Industry in Mexico by Donald Hughes Shaw Submitted to the School of Industrial Management on April 11, 1960, in partial fulfillment of the requirements for the degree of Master of Science. ABSTRACT The hypothesis of this thesis is that high taxation on the base metals mining and smelting industry is likely to cause a decline in that industry in the near future, and such a decline would seriously affect the nation's economy.

  • Initial Determinants of Mexican Mass Migration
    Initial Determinants of Mexican Mass Migration David Escamilla-Guerrero [email protected] London School of Economics November 8, 2018 Abstract The paper addresses the determinants of the Mexican-US migration flow in its begin- nings (1884-1910). Exploiting an original data set based on individual border crossings from 1906 to 1908, I present for the first time, the spatial distribution of the flow at the local level. The micro data reveal that Mexican and American historiography misrepresented the composition of the flow regarding the immigrant’s locations of birth and last residence. Contrary to previous literature, most immigrants came from the border states rather than from the central plateau of Mexico. In addition, internal migration was not the main mechanism to cross the border since 60 percent of the flow was characterized by direct emigration to the United States. The quantitative assessment reveals that market potentials and Mexican immigrant networks in the US were the main pull factors rather than the US-Mexico wage gap. On the other hand, differences in living standards across Mexico were the main push factor. Despite their importance for the Mexican economy, railways had a limited effect on the migration flow during the Age of Mass Migration. Keywords: labor migration, railways, institutions, Mexico JEL Classification Numbers: N36, N76, F22, J61 Acknowledgments: I am especially grateful to my PhD supervisors Eric Schneider and Joan Rosés for their guidance and invaluable comments. I thank Chris Minns, Zachary Ward, Neil Cummins, Alfonso Cabreros-Zurita, León Fernández-Bujanda and Mattia Bertazzini for their extensive feedback; and Daniela Gutiérrez and Marco Villeda for their assistance on the data transcription.

One of the keys to position the country as a global trade leader over the coming decade is the development of an international logistics capability that joins production, cost, quality and customer service to provide an integrated supply chain, indispensable to new business and trade practices. Mexico has positioned itself as an attractive location for productive investment, something that has favored the recent increase in advanced manufacturing industries based in the country, such as aerospace, automotive, electronics, medical and food processing, among others. That has further encouraged investment in multi- modal transport corridors comprising inland ports, industrial parks and free trade zones in order to develop Mexico as a logistics platform and link it to world markets. In most recent years, Mexico prepared a very ambitious infrastructure program in history, building and modernizing a 133,000 kilometer network of highways, 76 airports (64 with international flights), and 27,000 kilometers of railroad and 117 maritime ports – of which 68 are containers ports.
