Income inequality among minority farmers in China: Does social capital have a role?

We used recently available household panel data collected by China's National Bureau of Statistics to examine the effects of natural, human, material, and social capital on income inequality among minority farmers in China's Xinjiang Province between 2011 and 2012. Results obtained from panel quantile regression and correlated random effects’ models show that income inequality and the poverty of ethnic farmers have been decreasing to some extent. Results also indicated that human capital exacerbates income inequality among the minorities, whereas the effect of natural capital on income inequality is not evident. Social and material capital reduce income inequality among ethnic minorities. Results from the decomposition of the Gini coefficient indicate that material and social capital contribute to a substantial majority of the income inequality in the region.     

How much would low- and middle-income countries benefit from addressing the key risk factors of road traffic injuries?

Abstract

Despite strong advocacy, the UN Decade of Action for Road Safety (2011–2020) is ending with most low- and middle-income countries (LMICs) no closer to the Sustainable Development Goals target of reducing traffic mortality by half. In contrast, most high-income countries (HICs) have seen large benefits in recent decades from large-scale safety interventions. We aimed to assess how much LMICs would benefit from interventions that address six key risk factors related to helmet use, seatbelt use, speed control, drink driving, and vehicle design for safety of occupants and pedestrians. We use a comparative risk assessment framework to estimate mortality and health loss (disability adjusted life years lost, DALYs) that would be averted if these risks were reduced through intervention. We estimate effects for six countries that span all developing regions: China, Colombia, Ethiopia, India, Iran, and Russia. We find relatively large benefits (27% reductions in road traffic deaths and DALYs) from speed control in all countries, and about 5%-20% reductions due to other interventions depending on who is at risk in each country. To achieve larger gains, LMICs would need to move beyond simply learning from HICs and undertake new research to address risk factors particularly relevant to their context.     

Communication and Promotion Decisions in Retailing: A Review and Directions for Future Research

Communication and promotion decisions are a fundamental part of retailer customer experience management strategy. In this review paper, we address two key questions from a retailer's perspective: (1) what have we learned from prior research about promotion, advertising, and other forms of communication and (2) what major issues should future research in this area address. In addressing these questions, we propose and follow a framework that captures the interrelationships among manufacturer and retailer communication and promotion decisions and retailer performance. We examine these questions under four major topics: determination and allocation of promotion budget, trade promotions, consumer promotions and communication and promotion through the new media. Our review offers several useful insights and identifies many fruitful topics and questions for future research.     

Medical travellers’ perspectives in selecting in-patient services at selected private hospitals in Sri Lanka

The Sri Lankan government has clear plans to develop medical tourism as an industry. Availability of high-quality medical professionals and accredited hospitals has encouraged medical travellers to come to Sri Lanka and to expand the medical tourism industry in the country. The purpose of this cross-sectional study was to describe medical travellers’ perspectives in seeking in-patient services at selected four private hospitals in Sri Lanka. Foreign national in-patients (n?=?252) were interviewed using an interviewer-administered questionnaire. The response rate was 93.25%. The majority (68.1%) were Maldivians followed by Indians (20.4%) and 51.1% sought surgical care. Availability of high-quality medical professionals (94.2%) and accredited hospitals (81.3%), easy visa (90.2%) were top reasons to select Sri Lanka. Medical travellers faced difficulties in communication (37.4%), transport (31.9%), accommodation (57%) and finding quality food (41.7%). The study recommends improvement of infrastructure and support services for medical travellers and that private hospitals obtain international accreditation to improve medical tourism potentials.     

Apparent Gains,Hidden Costs: Examining Adoption Drivers,Yield, and Profitability Outcomes of Rotavator Tillage in Wheat Systems in Nepal

The ‘high speed’ rotavator is used for shallow tillage to create a fine tilth and incorporate crop residues, often with a single tractor pass. Rotavator tillage has spread quickly in many parts of South Asia, despite short-term experimental trials suggesting deteriorating soil quality and crop yield penalties. Evidence of rotavator impacts on farmer fields across soil gradients and time is largely absent. From a farm household survey conducted among wheat farmers in Nepal, we estimate wheat yield and profitability outcomes for rotavator adopters and non-adopters using propensity score matching. We find that rotavator adoption leads to inferior outcomes, despite significant cost savings for land preparation (US$ 11–15 per hectare). With rotavator adoption, farmers lose about 284–309 kg of wheat grain and about US$ 93–101 of profits on average per hectare per season, and these penalties increase with longer-term use of the technology. Adoption of rotavator appears to be driven by the cost and time savings for land preparation. Against this backdrop, new policy and extension efforts are required that discourage rotavator use and favour more sustainable tillage technologies.     

Hybrid Choice Models: Progress and Challenges

We discuss the development of predictive choice models that go beyond the random utility model in its narrowest formulation. Such approaches incorporate several elements of cognitive process that have been identified as important to the choice process, including strong dependence on history and context, perception formation, and latent constraints. A flexible and practical hybrid choice model is presented that integrates many types of discrete choice modeling methods, draws on different types of data, and allows for flexible disturbances and explicit modeling of latent psychological explanatory variables, heterogeneity, and latent segmentation. Both progress and challenges related to the development of the hybrid choice model are presented.     

Geo-Logics of Power: Disaster Capitalism,Himalayan Materialities,and the Geopolitical Economy of Reconstruction in Post-Earthquake Nepal

ABSTRACT

The 2015 earthquakes in Nepal killed more than 9,000 people, displaced millions of people and deeply affected the economy. The earthquakes and reconstructions processes also transformed Nepal into a complex terrain of geoeconomic accumulation and geopolitical manoeuvring, including major international capital flows, the promulgation of a new constitution, an economic blockade by India and the expansion of trade corridors with China. Building on critiques of ‘disaster capitalism’, we propose and mobilize the concept of ‘geo-logics of power’ to draw further attention to the materialities of geopolitical and geoeconomic processes shaping reconstruction in post-earthquake Nepal. Focusing on two trans-Himalayan corridors connecting Nepal and China, we argue that the Nepal experienced a particular form of disaster capitalism: one in which the geo-logics of power – including trans-Himalayan discourses, practices, and materialities – came to shape political and economic transformations of a country long portrayed as a ‘buffer’ state between Indian and China. More broadly, we suggest that geo-logics of power result from a combination of geopolitical and geoeconomic power dynamics informed by geological formations and associated socio-natural processes.     

Injury care in low- and middle-income countries: identifying potential for change

The epidemiologic, demographic, and socio-political transitions underway in many low- and middle-income countries (LMIC) are associated with a substantial burden of disease due to injuries. LMIC have devoted relatively little attention to the injury problem. This paper argues that whereas prevention remains paramount, improving health care services for injuries will also contribute to reducing the burden. It examines the reasons for the relative inaction in LMIC to date, and contrasts this to high-income countries (HIC) which have seen substantial falls in mortality from improved trauma care systems. Mortality data, although readily available, are the tip of the clinical iceberg and there is a need for better-quality hospital data that can be used to monitor any future improvements. Models of trauma care from HIC are reviewed. It is suggested that the greatest potential for improvement can be achieved if entire trauma systems are improved, including pre-hospital, hospital and rehabilitation care. LMIC may not be able to afford the whole system and improving the most sensitive components of the system may be a better option. Models of trauma care developed in HIC need careful consideration to determine their effectiveness, appropriateness, affordability and equity implications for LMIC. Imports of blueprints from elsewhere are likely to fail; context sensitive and appropriate policies need to be developed locally through a consultative process. Effective working needs to be across disciplines, involving consultation with stakeholders, and requires investment in education, training and equipment. The evidence base for trauma services in LMIC is almost non-existent, highlighting the urgent need for research in these settings.     

Real wages,real interest rates,and the Phillips curve

This article argues that any analysis of a Phillips curve should include the real interest rate in addition to inflation and real wages as any changes in the interest rate changes the labour–capital input mix in the production process leading to a change in the level of employment in the economy. To justify this argument a Phillips curve model is developed, which includes the real interest rate in addition to inflation and real wages. After the diagnosis of the time series properties of the data, an error correction model is developed and estimated using a set of US annual data from 1948 to 1996. The estimated parameters of the model do suggest that one should really take into consideration of the real interest rate while analysing the Phillips curve. A non-nested test (F-test) also suggests that the Phillips curve model with real interest rate as an additional variable performs better than the conventional method that does not include the real interest rate.     

Carbon Subsidies,Taxes and Optimal Forest Management

We consider the effect of carbon credit payment schemes on forest owners’ land use and harvest decisions. We study two possible credit allocation regimes: one where credits are allocated according to the actual amount of carbon sequestered by the trees on a piece of land and another where credits are allocated according to the long-run potential to sequester carbon on the land. Using a real options model with uncertain future timber prices, we examine the effect on the timing of harvests and the replanting-abandonment decision. We show that both schemes discourage deforestation. Compensating growers for actual carbon sequestration leads to longer rotation periods between harvests, while basing compensation only on the long-run potential level of sequestration induces shorter rotation periods. The former scheme leads to greater benefits of carbon sequestration at lower cost than the latter scheme. Although inducing moderate levels of sequestration is expensive under both schemes, the cost falls dramatically when the level of payments climbs above some threshold. Indeed, providing the payments are sufficiently generous, carbon credit payment schemes offer an effective means of increasing carbon sequestration.
