| Exchange rates have long been thought to have an important impact on the export and import of goods and services, and, thus, exchange rates are expected to influence the price of those products that are traded. At the same time, energy impacts commodity production in some very important ways. The use of chemical and petroleum derived inputs has increased in agriculture over time; the prices of these critical inputs, then, would be expected to alter supply, and, therefore, the prices of commodities using these inputs. Also, agricultural commodities have been increasingly used to produce energy, thereby leading to an expectation of a linkage between energy and commodity markets. In this paper, we examine the price relationship through time of the primary... |

| Crude oil price speculation during 2000s could have increased installed capacity in corn ethanol plants beyond what was warranted by the market factors. We use Muth’s commodity pricing model and Flood and Garber’s tests to test for speculative investment in US corn ethanol industry. The ethanol price expectations are derived using a system of supply-demand-inventory describing US ethanol markets under rational expectations (perfect foresight). These price expectations can help differentiate the installed capacity into two: capacity supported by the market fundamentals and the probable capacity that is installed based on speculation. Econometric estimation procedures and functional form approximations are discussed. |

| Este estudio es una exploración cuantitativa del impacto de la actividad minero-metálica en los hogares de la sierra peruana, en el que hemos empleado métodos estándares de evaluación de impactos. Sobre la base de datos de la ENAHO 2003/04, realizamos un análisis separado por hogares rurales y urbanos. Encontramos una asociación positiva entre la minería y los ingresos y gastos de las familias urbanas, pero no de las familias rurales. En este último caso, sin embargo, sí encontramos evidencia de una menor tasa de pobreza relacionada con la presencia minera. Además, hallamos correlaciones negativas entre minería y acceso a servicios de agua y desagüe y una mayor incidencia potencial de enfermedades crónicas y agudas, especialmente en los hogares urbanos.... |
