'Money illusion has been a non-starter among academic economists for a long time. It has been thoroughly banned from the economists’ research agenda with the advent of the rational expectations revolution in the 1970s. Back then, it was a matter of principle to account for all economic phenomena, including macroeconomic ones, by assuming that all agents are fully rational and that all agents know that everyone else is fully rational. Fortunately, those days are over in most quarters of the profession. With the emergence of behavioral and experimental economics as a field in the last two or three decades, economists have started to rediscover their fascination with the topic and have started asking systematically when money illusion matters, and if so, why.Helena Chytilova’s timely book recounts the remarkable academic journey of the concept of money illusion and she contributes to a currently hot topic in research by taking stock of the relevant literature in this emerging field. Importantly, she provides new experimental evidence suggesting that money illusion matters for nominal inertia even if the decision makers involved are economically literate, i.e. have undergone solid training in economics. This finding is intriguing as it seems to imply that economic training alone will not necessarily be a safeguard against the economic harm potentially caused by money illusion.' — Jean-Robert Tyran, Professor of Economics, University of Vienna, Austria
