Second-best tax policy and natural resource management in growing economies

This paper investigates the exploitation of natural resources in a growing economy within a second-best fiscal policy framework. Agents derive utility from two types of consumption goods—one which relies on a natural resource input and one which does not—as well as from leisure and from natural resource amenity values. We connect second best policy to essential components of utility by considering the elasticity of substitution among each of the four utility arguments. The results illustrate potentially important relationships between amenity values and leisure. When amenity values are complementary with leisure, for instance when natural resources are used for recreation, optimal taxes on goods produced with natural resources generally increase over time. On the other hand, optimal taxes on goods produced from natural resources generally decrease over time when leisure and amenity values are substitutes. Under some parameterizations, complex dynamics leading to non-monotonic time paths can emerge.     

Wealth Accounting,Exhaustible Resources and Social Welfare

The empirical literature on natural resource accounting uses methods which implicitly or explicitly entail measuring changes in total resource asset value when an exhaustible resource is depleted. In contrast, the growth theoretic literature on saving, social welfare and sustainable development is built upon a central finding, that the change in real wealth (as measured by net or ‘genuine’ saving) is proportional to the change in social welfare. We show that the change in total wealth exceeds the change in real wealth in optimal and non-optimal models of resource-extracting economies. This suggests that the change in social welfare is over-estimated when the change in total resource asset value is used as the measure of depletion. A simple empirical exercise, using World Bank data on ‘adjusted net saving’, reinforces the results from theory.     

Shedding “light” on marriage: The influence of skin shade on marriage for black females

The inter-racial marriage gap that opened in the past 50 years is generally attributed to a decline in the availability of young black marriageable men. We contend that the associated shortage of desirable men in the marriage market provides those black men who are sought after with the opportunity to attain a high status spouse, which has placed a premium on black women with lighter skin. We provide evidence, based on data drawn from the Multi City Study of Urban Inequality, consistent with this hypothesis. Our theoretical analysis of the marriage market reveals that marriage promotion policies to increase the desire to marry on the part of young black women will serve to exacerbate the importance attached to skin shade.     

The Heterogeneity of Socially Responsible Investment

Many writers have commented on the heterogeneity of the socially responsible investment (SRI) movement. However, few have actually tried to understand and explain it, and even fewer have discussed whether the opposite – standardisation – is possible and desirable. In this article, we take a broader perspective on the issue of the heterogeneity of SRI. We distinguish between four levels on which heterogeneity can be found: the terminological, definitional, strategic and practical. Whilst there is much talk about the definitional ambiguities of SRI, we suggest that there is actually some agreement on the definitional level. There are at least three explanations which we suggest can account for the heterogeneity on the other levels: cultural and ideological differences between different regions, differences in values, norms and ideology between various SRI stakeholders, and the market setting of SRI. Discussing the implications of the three explanations for the SRI market, we suggest that there is reason to be sceptical about the possibilities of standardisation if not standardisation is imposed top-down. Whether this kind of standardisation is desirable or not, we argue, depends on what the motives for it would be. To the extent that standardisation may facilitate the mainstreaming of SRI, it could be a good thing – but we entertain doubts about whether mainstreaming really requires standardisation.
