Regression Diagnostics: Identifying Influential Data and Sources of Collinearity

Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

Estimation and Inference in Econometrics

Indigenous groups offer alternative knowledge and perspectives based on their own locally developed practices of resource use. We surveyed the international literature to focus on the role of Traditional Ecological Knowledge in monitoring, responding to, and managing ecosystem processes and functions, with special attention to ecological resilience. Case studies revealed that there exists a diversity of local or traditional practices for ecosystem management. These include multiple species management, resource rotation, succession management, landscape patchiness management, and other ways of responding to and managing pulses and ecological surprises. Social mechanisms behind these traditional practices include a number of adaptations for the generation, accumulation, and transmission of knowledge; the use of local institutions to provide leaders/stewards and rules for social regulation; mechanisms for cultural internalization of traditional practices; and the development of appropriate world views and cultural values. Some traditional knowledge and management systems were characterized by the use of local ecological knowledge to interpret and respond to feedbacks from the environment to guide the direction of resource management. These traditional systems had certain similarities to adaptive management with its emphasis on feedback learning, and its treatment of uncertainty and unpredictability intrinsic to all ecosystems.

Dryland areas occur in both the highlands and the lowlands of Ethiopia and cover over 60 % of the country’s land mass. They support pastoralist, agro-pastoralist and hunter-gatherer communities, and their long-standing institutions to manage local resources on a fairly equitable basis. However, this autonomy has been significantly eroded by successive governments’ policy of agricultural expansion and modernization, driven by the growing global demand for food and fuel. By reviewing historical trends and current statuses, this study attempts to identify the driving forces behind this fast-changing land use and its impacts on communities and resources. The review shows that government’s generous land leases to national and global investors, encroachment by smallholder farmers from the highlands, state-initiated settlements of poor households, and individualization of the commons by some community members themselves have further undermined the already weakening customary tenure arrangements (which were never as clearly defined in the lowlands as in the highlands). The problem, however, needs to be seen against the constitutional rights of all citizens who want to be farmers to get land anywhere in the country. Unless these issues are addressed, indigenous communities will continue to be exposed to expropriation and unable to assert their rights in the face of more powerful actors. The chapter concludes by stressing the need to formulate and enact policies and legal frameworks to ensure the livelihoods of dry lowland communities in light of the mounting interests of multiple actors and of other stakeholders’ rights and responsibilities as stipulated in the Ethiopian Constitution.
