Energy demand in the transportation sector of Mexico

This paper report results of an analysis of the demand for energy in the Mexican transport sectors, focusing on the railroad, air transport and motor vehicle modes. The approach is an econometric one with emphasis placed on the structure for each mode. For two of the modes a two-stage approach is employed where in the first stage demands for services from the particular mode are modeled, and in the second stage demand is treated as a derived demand from these transport services. For the motor vehicle mode, gasoline demand is considered as the product of gasoline consumption per vehicle times the total number of vehicles, and then these components are related to economic and structural variables. Diesel demand of motor vehicles is modeled in a more reduced from approach. The principal finding is that changes in income play a more important role in affecting energy demand than do changes in energy prices, especially in the railroad and air transport sectors. For the gasoline and diesel fuel demand in the monitor vehicle sector, however, price is of substantial importance.

How should we write the history of twentieth-century economics?

The modern economist looks at a textbook history of nineteenth-centuryeconomics and wonders what, for the twentieth century, willcorrespond to the chapter titles of 'Malthus', 'Ricardo', 'TheMills', 'Marx', and 'The Rise of Marginalism'. Will monetarismsurvive editing? Will game theory rate its own section? WillKeynes be a hero or a goat? Economists look to the historianand wonders how the historian decides what is important, andhow we go about deciding what will go into a future historybook. Eschewing narratives of progress, this paper surveys alternativehistoriographies for constructing a history of twentieth-centuryeconomics, and suggests that the new discipline of science andtechnology studies provides a number of useful frameworks fortelling the story.
