This insightful Modern Guide offers a broad coverage of questions and controversies encountered by contemporary economists. A refreshing approach to philosophy of economics, chapters comprise a range of methodological and theoretical perspectives, from lab and field experiments to macroeconomics and applied policy work, written using a familiar, accessible language for economists. Highlighting key areas of methodological controversy, the Modern Guide looks at estimating utility functions in choice data, causal modelling, and ethics in randomised control trials. Chapters further explore topical issues, including: economists’ attitudes to other disciplines; gender bias in economic research; methods of modelling social influence in economics; behavioural welfare economics; anti-poverty policy controversies; and inflexible reliance on DSGE models in macroeconomics. Furthermore, it explores the implications of the last financial crisis for macroeconomic confidence, and ways to adapt abstract theory to everyday policy advice. Avoiding philosophical jargon, and with the majority of chapters written by economists, this Modern Guide will challenge economists and scholars of philosophy of economics to engage with different approaches to the topic. This will also be a useful tool for policy makers administering nudges, development initiatives, macro-forecasting and monetary policy.
