The book "Amartya Sen's Capability Approach" by Wiebke Kuklys offers an in-depth analysis of Amartya Sen's approach to welfare measurement, particularly regarding poverty and inequality in affluent societies like the United Kingdom. Kuklys argues that an individual's well-being should be measured not just by income, but by the actual opportunities available to them. The first two chapters describe the Capability Approach from a standard welfare economics perspective and provide a comprehensive literature review of empirical applications in this research area. The subsequent chapters employ novel econometric techniques to operationalize the concepts of functionalities and capabilities, examining inequality and poverty in the context of capabilities. The findings indicate that measuring capabilities is a valuable addition to traditional monetary analysis, especially for capability-disadvantaged individuals with disabilities.
