"One of the recurring themes in the sustainability literature has been the legitimacy of using an economic framework to account for natural resources. This paper examines the potential for substituting between different inputs in the generation of income, where the inputs include natural resources such as land and energy resources. A nested constant elasticity of substitution (CES) production function is used to allow flexibility in the estimated elasticities of substitution. Also, with this specification, natural resources and other inputs are combined in different levels of the function, thus allowing for different levels of substitutability. Institutional and economic indicators are also incorporated in the production function estimated. Results show that the elasticities derived from functions involving land resources were generally around one or greater, implying a fairly high degree of substitutability. Furthermore, changes in trade openness and private sector investment have a statistically significant and direct relationship with income generation. No statistically significant relationship between income and any of the institutional indicators was found. "--World Bank web site.

Hoe grondig de beheersing van de spraakkunst, zinsbouw en spelling van een vreemde taal ook is, dit is nog geen garantie voor een voldoende kennis van de taal in kwestie. De buitenlander zal tot de ontdekking komen dat hij in de praktijk onvoldoende kennis heeft van bepaalde zegswijzen en uitdrukkingen om zich vlot te kunnen uitdrukken. De opzet van dit boek is aan dit euvel te verhelpen. Een grondige studie van het idiomaticum zal leiden tot een rijkere taalbeheersing en een vlotter uitdrukkingsvermogen.
