This paper explores both theoretically and empirically whether or not the willingness to pay (WTP) for pollution control varies with income. Our model indicates that the income elasticity of the marginal WTP for pollution reduction is only constant under very restrictive conditions, which are not necessary for an environmental Kuznets curve relationship between pollution and income. Our empiric...

The aim of this paper is to calculate the effects of air travel demand determinants in Middle Income Countries (MICs). Through static and dynamic panel data models from 32 countries during the period from 2002 to 2008, we found that the income elasticity is the most important determinant and that it is slightly higher than one. Income growth multiplied by income elasticity accounts for 75 perce...

This paper investigates the effects of bequest taxes and the income of children on the lifetime charitable contributions of parents. Using matched income tax records for parents and children, the results show a positive elasticity of 0.6 for contributions with respect to the tax price of bequests. The paper also finds that the income of children affects the amount that parents contribute to cha...

Estimates of the value of a statistical life (VSL) establish the price government agencies use to value fatality risks. Transferring these valuations to other populations often utilizes the income elasticity of the VSL, which typically draw on estimates from meta-analyses. Using a data set consisting of 101 estimates of the income elasticity of VSL from 14 previously reported meta-analyses, we ...

This paper investigates why children work by studying the wage elasticity of child labour supply. It is argued that a negative wage elasticity favours the hypothesis that poverty compels work whereas a positive wage elasticity would favour the alternative view that children work because the relative returns to school are low. Using data for 2400 households in rural Pakistan, we estimate structu...

 International trade causes that markets to become more competitive and small-medium sized enterprises (SMEs) learn to compete effectively within this increasingly competitive global market place. SMEs are able to take advantage of increased opportunities in domestic markets that follow from international trade. It is indeed a way for internationalization of SMEs. This paper analyzes income and...
