Financial aggregation of risks for MSMEs in developing economies: a conceptual framework of financial aggregation and microinsurance effects

Business vulnerability is a function of the extent of risks faced and the ability of the business to adapt to adverse changes in circumstances. Financial Aggregation arises out of the link between economic interactions at the micro level and their macro based risks Microbusinesses in developing countries are often highly vulnerable to a range of risks including natural disasters, corruption, poor weather conditions and illness. This vulnerability creates a need for insurance but ability to take out appropriate insurance is frequently limited by financial resources, availability of insurance policies and information on these policies and financial education levels. On the supply side, microinsurers are faced with high marketing and administrative costs and the microinsurance market is further distorted by information asymmetries, adverse selection and moral hazards. This limits interest in the microinsurance market from commercial providers, with microinsurance frequently being available through non-profit agents. This paper investigates the relationship between vulnerability, risk appetite of microbusinesses and their propensity to insure. In building a conceptual framework, we explore the factors that impact financial aggregation and the uptake of microinsurance. We observe additionally that improved financial education and more effective information may help to increase the extent and quality of microinsurance

Using non-participant observation to uncover mechanisms: insights from a realist evaluation

This article outlines how a realist evaluation of dementia care in hospitals used non-participant observation to support the refinement and testing of mechanisms likely to lead to the use of person-centred care. We found that comments and explanations of their actions from hospital staff during observation periods provided insights into the reasoning that generated their actions for care in real time. This informed subsequent data collection and analysis. Two worked examples of mechanisms first identified during non-participant observation demonstrate (1) how they were uncovered, and (2) how this informed research activities for theory refinement. Early, iterative engagement with the analytic process, primarily involving reflection and debate with the research team, maximised the potential of observation data to support surfacing underlying mechanisms, linking them to specific contexts and outcomes.Peer reviewedFinal Accepted Versio

Constraining recent lead pollution sources in the North Pacific using ice core stable lead isotopes

Trends and sources of lead (Pb) aerosol pollution in the North Pacific rim of North America from 1850 to 2001 are investigated using a high-resolution (subannual to annual) ice core record recovered from Eclipse Icefield (3017 masl; St. Elias Mountains, Canada). Beginning in the early 1940s, increasing Pb concentration at Eclipse Icefield occurs coevally with anthropogenic Pb deposition in central Greenland, suggesting that North American Pb pollution may have been in part or wholly responsible in both regions. Isotopic ratios (208Pb/207Pb and 206Pb/207Pb) from 1970 to 2001 confirm that a portion of the Pb deposited at Eclipse Icefield is anthropogenic, and that it represents a variable mixture of East Asian (Chinese and Japanese) emissions transported eastward across the Pacific Ocean and a North American component resulting from transient meridional atmospheric flow. Based on comparison with source material Pb isotope ratios, Chinese and North American coal combustion have likely been the primary sources of Eclipse Icefield Pb over the 1970–2001 time period. The Eclipse Icefield Pb isotope composition also implies that the North Pacific mid-troposphere is not directly impacted by transpolar atmospheric flow from Europe. Annually averaged Pb concentrations in the Eclipse Icefield ice core record show no long-term trend during 1970–2001; however, increasing 208Pb/207Pb and decreasing 206Pb/207Pb ratios reflect the progressive East Asian industrialization and increase in Asian pollutant outflow. The post-1970 decrease in North American Pb emissions is likely necessary to explain the Eclipse Icefield Pb concentration time series. When compared with low (lichen) and high (Mt. Logan ice core) elevation Pb data, the Eclipse ice core record suggests a gradual increase in pollutant deposition and stronger trans-Pacific Asian contribution with rising elevation in the mountains of the North Pacific rim
