In this paper, we focus on the issue of water loss caused by leakage from obsolete water mains. We develop in this theoretical paper, a cost minimization problem of a water utility that faces leakage from water mains. Our framework enables us to determine the optimal water main quality index...

This paper formulates a demand model for residential water in Sri Lanka using the Stone-Geary functional form. This functional form has two main advantages when compared with Cobb-Douglas: non-constant price elasticities and; it considers water consumption as two components – a fixed and a...

We examine how scarcity pricing can be used to assist with urban water demand management in Sydney in low rainfall periods using an estimated aggregate daily water demand function. Modelling shows that current water supplies and water prices are inadequate to prevent Sydney reaching critically...

William Forster Lloyd's 1833 sketch about poor cattle on the commons and the well-fed animals on the adjacent enclosures published in his 'Two lectures on the checks to population' has hitherto been assessed as one starting point of the economics of renewable resources. In the 20th century the...

This paper investigates whether changes in climatic conditions significantly contribute to incidence of poverty in the Philippines. Due to the lack of sufficient regional estimates of poverty, this study utilized food cpi data to proxy for poverty level. The relationship between poverty level...

Classical household theory predicts that adolescents facing a developed labour market should invest in formal education. In contrast, it is obvious that adolescents in subsistence economies should choose learning-by-doing approaches to working on the family farm. However, it is unclear what...

The paper develops a model that shares common features with the computable general equilibrium (CGE) models. It is used to address two questions. First, what are the future prospects of a green gross domestic product (GDP), should we be concerned for resource degradation or not, and to what...

This study assesses the potential cost-effectiveness of incentive payment programs relative to traditional top-down regulatory programs for biological conservation. We develop site-level estimates of the opportunity cost and the nonmonetized biological benefits of protecting biodiversity...
