“…Traditional thinking on TFP also fails to adequately capture fluctuations in relative natural-resource wealth, which may be affected by the ore grade or the status of ecological systems. For example, changes in copper ore grade can have significant impacts on mining productivity; and the deterioration or recovery of ecological systems and externalities can impact the trend of GDP (see Sotelsek and Laborda, 2010). For this reason, for several years, the Central Bank of Chile has been making estimates that separate out mining or natural resources, which undoubtedly is very useful for understanding the domestic macroeconomic situation.…”

This article reviews the trend of investment in Chile and its relationship with economic growth since the 1973 coup d'état; and it documents how investment remains the main growth driver. Notwithstanding that fact, innovation helps to mitigate diminishing returns from natural resources, while technology-intensive investment, such as broadband infrastructure, helps to diversify the production matrix. The article shows how a persistent increase in the investment ratio in 1990-1998 supported GDP growth of 7.1% per year; but since 1999 investment has wavered, and average growth dropped to below 4%. The article examines the macroeconomic environment and its real instability since 1999, along with investment in infrastructure, the quality of natural resources and environmental services; and it identifies challenges for boosting both investment and innovation, diversifying the production matrix and its agents, and moving towards inclusive growth.

Resumen: Este trabajo de investigación presenta un análisis de la eficiencia técnica de las empresas del sector carbón y sus derivados en Colombia, durante el periodo 2011-2014. Como fundamentación teórica se utilizaron los conceptos de análisis envolvente de datos (DEA), específicamente el modelo CCR-O, enfocado en salidas y en la técnica multivariada de análisis discriminante. Para el desarrollo de la investigación se realizó un estudio empírico racional, con un enfoque evaluativo, que permitió establecer una estructura DEA para valorar las eficiencias. Para esta investigación se trabajó con 14 grandes empresas del sector minero en Colombia; como fuente de información primaria se tomó la reportada por la Superintendencia de Sociedades en los respectivos años. Con base en la estructura DEA, se valoraron las eficiencias de las empresas y se establecieron aquellas que se constituyeron en referentes de evaluación de las empresas ineficientes; seguidamente, se calcularon las proyecciones de las variables de salida que permiten que las empresas ineficientes alcancen las eficiencias de acuerdo con el modelo CCR-O enfocado en salidas. Por último, se utilizó la técnica análisis discriminante, que permitió validar la pertenencia de una empresa del sector a ser eficiente o no. La eficiencia promedio de las empresas bajo el modelo DEA en el periodo de estudio alcanzó un nivel alto, de 84,5 % y la técnica análisis discriminante indicó una validación del 80,3 %. Este trabajo aporta criterios a los responsables de la toma de decisiones para mejorar la eficiencia en el sector.

This paper assessed the impact of climate change on farm-level productivity and technical efficiency in the Punjab province of Pakistan. The stochastic production frontier model was employed at the farm household level for 3 yr of panel data (n = 537) covering 3 cropping systems (rice-wheat, cotton-wheat, and mixed wheat) from 3 different agro-ecologies and 17 of 36 districts of Punjab. Though the use of inputs was found to have a positive impact on farm production, results highlight the strong negative impacts of the increase in the long-run temperature normals and fluctuating precipitation across the crop production seasons. Weather shocks and socioeconomic factors of the farm family significantly contributed to the farm’s technical efficiency. A mean technical efficiency score of 0.82 suggests that with the use of climate-smart technologies and improving farm management involving better use of production inputs, there is potential for improvements in farm-level technical efficiency. The declining trend in the mean technical efficiency due to weather shocks necessitates the adoption of climate-smart agricultural practices. However, this requires that farmers should be supported with targeted coping options for expected weather shocks differentiated by crop production zones. A well-coordinated climate and extension service can support the adoption of climate-smart agriculture for sustainable crop production.
