Error in Economics $45.58 What is the correct concept behind measures of inflation? Does money cause business activity or is it the other way around? Shall we stimulate growth by raising aggregate demand or rather by lowering taxes and thereby providing incentives to produce? Policy-relevant questions such as these are of immediate and obvious importance to the welfare of societies. The standard approach in dealing with them is to build a model, based on economic theory, answer the question for the model world and then apply the results to economic phenomena outside. Data come in, if at all, only in testing a limited number of the model’s consequences. Despite some critical voices, economic methodology too has by and large subscribed to a "theory first" approach to applied economics. Error in Economics systematically develops an alternative to the theory-based orthodoxy. It places the methodical study of evidence at the centre of the scientific enterprise and thus provides a foundation for a methodology of evidence-based economics. But the book does not stop at the truism that claims should be based on the best available evidence. Rather, detailed studies in the areas of measurement, causal inference and policy analysis show what it means for a claim to be evidence-based in the context of a concrete case. The examples discussed concern topics as diverse as consumer price indices, radio spectrum auctions, the transmission mechanism, natural experiments on minimum wages and the evaluation of counterfactuals for policy. Error in Economics is essential reading for economic methodologists, philosophers of science and anyone interested in how claims about socio-economic matters are validated. |

Generalized Gaussian Error Calculus $172.99 The proposed book Generalized Gaussian Error Calculus addresses for the first time since 200 years a rigorous, complete and self-consistent revision of the Gaussian error calculus. Since experimentalists realized that measurements in general are burdened by unknown systematic errors, the classical, widespread used evaluation procedures scrutinizing the consequences of random errors alone turned out to be obsolete. As a matter of course, the error calculus to-be, treating random and unknown systematic errors side by side, should ensure the consistency and traceability of physical units, physical constants and physical quantities at large. The generalized Gaussian error calculus considers unknown systematic errors to spawn biased estimators. What’s more, random errors are asked to conform to the idea of what the author calls well-defined measuring conditions. This approach features the properties of a building kit: any overall uncertainty turns out to be the sum of a contribution due to random errors, to be taken from a confidence interval as put down by Student, and a contribution due to unknown systematic errors, as expressed by an appropriate worst case estimation. |

Befriend the Unknown $24.02 We live in a world where Mother Nature does not disclose her secrets readily, and man’s drive to comprehend and control the unseen forces is one of the great themes of human history. Where did we come from? What is our purpose? In Befriend the Unknown, author Ken Foo investigates a number of provocative and inspiring thoughts, ideas, phenomena, and entities from the beguiling realm of the unknown. Gathering research from the beliefs of reputable sages and great thinkers of all eras, Foo discusses a wide range of subjects that reflect unknown forces, such as Atlantis and riddles of the past, destiny, karma, mysticism, war and peace, the many faces of religion, the beauty of nature, reincarnation, free will, dharma, and more. Befriend the Unknown seeks to quench our thirst for answers to the unknown. Learn to come to grips that it is nature’s law that your present stay here is only temporary but likely to return again as another person or else there will be no such words as "soul," "karma" or "reincarnation." This is the basis of duality – the combination of the physical and spiritual self. |
