This note contends that crop mixtures are employed by farmers primarily as risk precautions and that the immediate objective of farmers is not only one of profit maximisation but also of stability of income. The results of an income stability model employed to verify this hypothesis seem to agree relatively well with existing information in parts of Northern Nigeria. 相似文献

The recent establishment of fourth-tier system as a distinct, but coordinating level of government in Imo State came with the expectation that it would facilitate community development. However, the underdevelopment situation of most communities dashed this expectation. Thus, this recent study adopted theory of postcolonial state as our analytical framework to interrogate the development utility of the fourth-tier system using mixed research methods for evidence gathering and analysis. The analysis revealed that the system grossly underperformed its development functions resulting from lack of stakeholders’ supports, which should be the basis for determination and implementation of fourth-tier system in Imo State. 相似文献

We compare several risk preference elicitation methods – including incentivised, non-incentivised, and framed methods as well as a traditional Likert survey question – in a developing country and empirically test how well consequent measures of risk attitudes predict risk taking behaviour. We find that Likert scale and non-incentivised framed survey questions are not sufficient substitutes for costlier incentivised methods in rural Niger. Instead, the incentivised framed question works best while a simplified incentivised lottery question works almost as well. More risk and ambiguity averse farmers are less likely to adopt fertiliser microdosing indicating the importance of insurance and strategies to promote learning. 相似文献

Surely there is a profound difference between inciting to arson by the use of words and inciting to revolution by the use of words. We do not have a ready word for the distinction, yet it is a deep and obvious one.—Harry Kalven, Jr. 相似文献

This paper reflects upon the gross discrepancies between the reassurances given in 2010 by the 2010-2015 UK Coalition Government that their budget and welfare cuts would fall ‘fairly’ across the income spectrum, and the reality of what had happened by the end of that government. It asks how the ‘distributional impact assessment’ provided with the 2010 Comprehensive Spending Review could have been so wrong. In seeking to answer this question, types of systematic bias are considered along with a discussion of ‘marginality’ in assessments of impact. Drawing upon the role of ‘power’ in impact assessment, it traces the ways in which methodological assumptions can eclipse the real life effects of policies behind ‘the average’ as well as by the unfair selection of the ‘unit-of-analysis’. 相似文献

In recent years, Azerbaijan–Israel relations have come to the foreground of politics in the Middle East and Caucasus region. Ties between Baku and Tel Aviv have been directly interlinked with their relations with Iran. The nature of the Azerbaijan–Israel partnership must be analysed in order to comprehend the balance of powers and energy security in the region. Even though there have been a number of works analysing the relationship by focusing on its role in regional military security, there is a gap in the discourse in terms of understanding the economic drivers of relations and the implications of the ties for regional energy security. Particular attention will be given to discussing Azerbaijan’s emerging role as a major energy producer that has already made a profound impact on the region as an ‘alternative’ to Iran in the aftermath of the recently imposed sanctions on Tehran's energy exports. It will be argued that the Azerbaijan–Israel relationship is built on solid economic grounds and it would be reasonable to expect the strength of the ties to be further intensified in the future. The article will also demonstrate that new developments in the energy security of the wider Middle Eastern region will affect the evolution of Azerbaijan–Israel ties and their rivalry with Iran in the next decade. 相似文献
