Economics is dominated by model building, therefore a comprehension of how such models work is vital to understanding the discipline. This book provides a critical analysis of the economist's favourite tool, and as such will be an enlightening read for some, and an intriguing one for others.

Numbers dominate global politics and, as a result, our everyday lives. Credit ratings steer financial markets and can make or break the future of entire nations. GDP drives our economies. Stock market indices flood our media and national debates. Statistical calculations define how we deal with climate change, poverty and sustainability. But what is behind these numbers? In How Numbers Rule the World, Lorenzo Fioramonti reveals the hidden agendas underpinning the use of statistics and those who control them. Most worryingly, he shows how numbers have been used as a means to reinforce the grip of markets on our social and political life, curtailing public participation and rational debate. An innovative and timely exposé of the politics, power and contestation of numbers.

Concern about the role and the limits of modeling has heightened after repeated questions were raised regarding the dependability and suitability of the models that were used in the run-up to the 2008 financial crash. In this book, Lawrence Boland provides an overview of the practices of and the problems faced by model builders to explain the nature of models, the modeling process, and the possibility for and nature of their testing. In a reflective manner, the author raises serious questions about the assumptions and judgments that model builders make in constructing models. In making his case, he examines the traditional microeconomics-macroeconomics separation with regard to how theoretical models are built and used and how they interact, paying particular attention to the use of equilibrium concepts in macroeconomic models and game theory and to the challenges involved in building empirical models, testing models, and using models to test theoretical explanations.

This book explains and assesses the ways in which micro, welfare and benefit-cost economists view the world of public policy. In general terms, microeconomic concepts and models can be seen to appear regularly in the work of political scientists, sociologists and psychologists. As a consequence, these and related concepts and models have now had sufficient time to influence strongly and to extend the range of policy options available to government departments. The central focus of this book is the 'cross-over' from economic modelling to policy implementation, which remains obscure and uncertain. The author outlines the importance of a wider knowledge of microeconomics for improving the effects and orientation of public policy. He also provides a critique of some basic economic assumptions, notably the 'consumer sovereignty principle'. Within this context the reader is in a better position to understand the 'marvellous insights and troubling blindnesses' of economists where often what is controversial politically is not so controversial among economists.

A comprehensive and up-to-date introduction to the mathematics that all economics students need to know Probability theory is the quantitative language used to handle uncertainty and is the foundation of modern statistics. Probability and Statistics for Economists provides graduate and PhD students with an essential introduction to mathematical probability and statistical theory, which are the basis of the methods used in econometrics. This incisive textbook teaches fundamental concepts, emphasizes modern, real-world applications, and gives students an intuitive understanding of the mathematics that every economist needs to know. Covers probability and statistics with mathematical rigor while emphasizing intuitive explanations that are accessible to economics students of all backgrounds Discusses random variables, parametric and multivariate distributions, sampling, the law of large numbers, central limit theory, maximum likelihood estimation, numerical optimization, hypothesis testing, and more Features hundreds of exercises that enable students to learn by doing Includes an in-depth appendix summarizing important mathematical results as well as a wealth of real-world examples Can serve as a core textbook for a first-semester PhD course in econometrics and as a companion book to Bruce E. Hansen’s Econometrics Also an invaluable reference for researchers and practitioners
