The 1929 stock market crash and subsequent depression saw classical economic thinking gradually give way to Keynesian central planning. The onset of stagflation in the 1970s ushered in neoliberalism and the advent of market deregulation. The 2008 financial crisis and ongoing recessionary fallout in most advanced economies would appear, on the face of it, to represent a similar historical turning point. Each of these crises called into question the credibility of conventional economics. Economists have never enjoyed a good reputation and 2008 marked a new nadir for the profession. However, we have yet to witness a radical transformation in economics of the sort that accompanied past upheavals. The policy options being debated today are largely an extension of past arguments that occurred in 1929 and 1970. Whether fiscal austerity versus growth or supply-side reforms versus demand stimulus measures, the positions of the leading players are entirely predictable and rest on established political allegiances. The opportunity for radical policy change is gradually fading. A crisis is going to waste. While public policy debates make little explicit reference to economic theory, Keynes’s comment that ‘practical men, who believe themselves exempt from any intellectual influence, are generally the slaves of some defunct economist’, is as true as ever. The rational choice models and general equilibrium theory that were developed in the 25 years after the second world war fed into the neoliberal policymaking of the quarter century that followed. These approaches remain the dominant academic paradigm, especially in finance theory and macroeconomics. They describe a world in which economic agents are rational, informed and make optimal decisions, and markets are either in, or geared towards, a state of equilibrium. Governments should, it is suggested, design economic policy on this basis. Differences between left and right turn on the narrow issue of the extent of ‘market failure’, a narrowly defined categorisation of legitimate reasons for policy intervention. The chief assumptions behind economic policymaking on the left and right are largely the same. The simplifying assumptions of an abstract theory are treated as universal truths about the real world. 1 But there are many alternative insights into economic phenomena. New economic thinking provides us with a far richer account of the economy, taking into account real-world human behaviour and the complex micro-level interactions that make up economic activity. Complexity, evolutionary and network economics are emerging fields of inquiry that offer a robust critique of neoclassical theory. They reject the latter’s deference to static equilibrium and perfect rationality, ignorance of innovation, downplaying of institutions, and assumption of zero-sum market transactions. They depict instead an economy made up of millions of overlapping activities, in which individuals, businesses and other institutions are highly connected and constantly interact, where preferences change and markets shift in unpredictable ways. It is a description that is immediately more recognisable in reality. While nods in the direction of behavioural economics have become fashionable, these ideas have received scant attention in policy circles. The market failure doctrine remains the required framework of microeconomic debate. Macroeconomic forecasting and analysis in the Treasury, the Bank of England and the Office for Budget Responsibility still draws on dynamic stochastic general equilibrium (DSGE) models and other staples of conventional economics. The majority of government economists and policymakers responsible for providing solutions to the most important economic challenges of the day – how financial instability might be tamed, how regional development can be boosted, and how the carbon emissions and other environmental side effects of economic growth can be reduced – are heavily influenced by the old neoclassical order. This must change. This book – which is the culmination of a two-year programme of work led by IPPR entitled New Era Economics, on whose advisory panel I have been a member – is the first serious attempt to bring insights from new economic thinking to policymakers. It draws together contributions from a group of respected economists and academics, which discuss what these new heterodox economic theories might mean for policy. In so doing, it is an attempt to kick-start a much-needed debate about how economic policymaking can be improved for the better. Changing the nature of mainstream economics will be no straightforward task. Yet if we do not take advantage of the current crisis to rethink the way we make economic policy, the opportunity will be missed. We need a far more eclectic approach to economic policy and economic debate. Thankfully, there is a solution and it lies in new economic thinking. This book sketches out the contours of a new approach to economic policymaking centred on this thinking. For that reason, it deserves a wide readership. 2 IPPR | Complex new world: Translating new economic thinking into public policy ABOUT The AUThOrs Pauline Anderson is a research fellow at the Centre for Research in Lifelong Learning, Glasgow Caledonian University.
