Efficiency of alternative property right allocations when farmers produce multiple environmental goods under the condition of economies of scope

The efficiency implications of different property right allocations when two environmental goods can be produced under the condition of economies of scope are analysed. It is assumed that an environmental agency – acting on behalf of the community – employs an auction-based mechanism to buy biodiversity services from farmers. However, farmers' production of biodiversity produces a second good as a by-product (e.g., mitigation of a river pollutant) that is valued by point-source emitters who are engaged in a pollution trading market. The efficiency implications of allocating the property right of the good, mitigation, to either the agency or farmers are analysed. If the agency owns the mitigation then the agency can sell mitigation to point-source emitters, offsetting the cost of biodiversity. If farmers own mitigation, then they sell it directly to point-source emitters. Assuming similar transaction costs associated with each property-right allocation, allocating the property right to farmers improves efficiency, as farmers take account of their private information to make profit-maximising decisions about the supply of biodiversity and mitigation; the agency would have trouble accessing this private information.     

Moving up the Ladder or Stuck on the Bottom Rung? Homeownership as a Solution to Poverty in Urban South Africa

In the global South, policies providing property titles to low-income households are increasingly implemented as a solution to poverty. Integrating poor households into the capitalist economy using state-subsidized homeownership is intended to provide poor people with an asset that can be used in a productive manner. In this article the South African "housing subsidy system" is assessed using quantitative and qualitative data from in-depth research in a state-subsidized housing settlement in the city of Cape Town. The findings show that while state-subsidized property ownership provides long-term shelter and tenure security to low-income households, houses have mixed value as a financial asset. Although state-subsidized houses in South Africa are a financially tradable asset, transaction values are too low for low-income vendors to reach the next rung on the housing ladder, the township market. Furthermore, low-income homeowners are reticent to use their (typically primary) asset as collateral security for credit, and thus property ownership is not providing the financial returns that titling theories assume.     

Is sexy better than funny? Disentangling the persuasive effects of pleasure and arousal across sex and humour appeals

Although it is well known that sex and humour can help sell products, hardly any research has examined whether there is something particular about sexual advertisements that makes them more persuasive than other appeals. The present research proposed an empirically robust way to test the persuasiveness of different emotional appeals (sex, humour, control) by matching them on pleasure and arousal levels. Two experiments (N = 162; N = 301) examined the combined persuasive effects of different levels of pleasure (moderate, high) and arousal (moderate, high) for sexual and nonsexual appeals. Study 1 used a 3 (appeal: sexual, humorous, control) × 2 (pleasure level: moderate, high) between-subjects design. Study 2 employed a 2 (appeal: sexual, control) × 2 (arousal level: moderate, high) × 2 (pleasure level: moderate, high) design. The main dependent measures were attitudes towards the ad, attitudes towards the brand, and purchase intentions. The results showed that highly pleasant ads increased persuasion regardless of arousal and content, and that sexual appeals outperformed nonsexual appeals only under conditions of moderate pleasure and high arousal.     

An ecological niche theory approach to the measurement of brand competition

Marketers have long advocated the use of ecological theory to study markets, but the abstract definitions of key constructs have hampered empirical applications. We take a first step in applying ecological theory to product markets by quantifying concepts such as niches, niche breadth, and niche overlap. We propose a new approach for measuring competitive intensity and identifying competitive submarkets. This measure defines competition between brands as the extent to which brands compete for the same customers. The approach is suitable for both durable and nondurable goods, for markets with many brands, and it can be used to assess competition between existing and hypothetical brands. We illustrate our approach using data on the magazine market and offer suggestions for future research.     

“We Learnt that Being Together Would Give us a Voice”: Gender Perspectives on the East African Improved-Cookstove Value Chain

ABSTRACT

Improved cookstoves (ICS) have been promoted for several decades, with little success. Advocates looking to drive uptake encourage greater involvement of women in ICS enterprises, on the largely unproven premise that women’s participation in the value chain will enhance their financial bottom line while giving a boost to ICS sales. This paper tests the validity of that premise, using qualitative evidence from East Africa. The analysis shows gender-differentiated outcomes for enterprises across the value chain. Women-led enterprises are significantly underrepresented at higher levels of the chain, where sales volumes are highest. Value-chain positioning also influences access to key inputs like finance, potentially reinforcing the gender divide in enterprise performance. The findings challenge the dominant narrative in the ICS field about the inevitability of the link between market participation and economic empowerment for women and indicate a need to look beyond conventional market models to enhance financial outcomes for women.     

Cereal production,undernourishment, and food insecurity in South Asia

South Asia remains one of the major strongholds of hunger in the world, despite the fact that, following the Green Revolution, cereal production in the countries of this region tripled during the second half of the 20th century. This study examines the role played by this increase in cereal production in improving the region’s nutrition and food security situation. We study the association between the different aspects of food security and cereal production in South Asia that have prevailed over the past 25 years. We find a beneficial role of the production and yield of cereals in lowering the extent of undernourishment. A 1% increase in cereal production and yield is associated with up to 0.84% decrease in the prevalence of undernourishment. The impact is significant over a period of 3 years. The positive effect is particularly evident in the case of rice and maize production. An improvement is seen in the aspects of availability, stability, and utilization of food security but not in the aspect of access. These findings are robust to alternative specifications and techniques. The results explain, in part, the means by which South Asian nations have managed to stall relative increases in extreme hunger and food insecurity.     

The disciplinary dilemma of tourism studies

Though tourism is a complex phenomenon crossing many disciplines, researchers tend to approach tourism studies from within the specific boundaries of the main discipline in which they have been trained. Existing tourism theory is thus fragmented and weak. This paper looks at the potential for developing more holistic and integrated theories than currently exist, and for tourism studies evolving into a distinct discipline. The current state of debate in this area is introduced, and several disciplines impacting on tourism studies are examined. Insights are drawn from two distinct philosophy of science perspectives, T.S. Kuhn and R.J. Bernstein. Suggestions are made for advancing the evolution and integration of tourism studies.
