8 D+C Vol.42.2015:2 The World Bank is backing away from standard economic orthodoxy. Its re- cent flagship report points out that policymakers must take into account sociological and psychological argu- ments. Economics is a social science strug- gling with self-doubt. Even leading international institutions are increasingly questioning orthodox views they held for many years. The obvious reason is the scale of the global financial crisis that be- gan in 2008, when Lehman Brothers, the investment bank, collapsed. The International Monetary Fund (IMF), for instance, has begun to admit that austerity is not working as expected. The Organisation for Economic Coopera- tion and Development (OECD) is increas- ingly focussing on how to tackle inequal­ ity, backing away from the old trickle-down paradigm according to which economic growth “lifts all boats”. Now the World Bank has abandoned standard economic reasoning. Its World Development Report 2015, which was published in late 2014, relies heavily on psychological and sociological arguments. It admits that “homo economicus”, the concept of the rational, utility-optimising individual on which most economic mod- elling is based, is wrong in three funda- mental ways: Human beings do not rationally ponder every single decision, but rather often decide “automatically”. The main reason is that people mostly have more relevant information than they can process. Human beings are social beings who are interested in cooperation. They appreci- ate the common good because it consti- tutes an important part of their personal well-being. In line with the first two arguments, hu- man beings rely on habits, generally held convictions and social norms. Vari- ous kinds of mental models and social beliefs form individual decisions. The World Bank team states that these things matter in development affairs and must be taken into account for policies to work out. For example, it is not enough to tell people about the economic benefits of saving money. Microfinance institutions should also design their schemes in ways that match their clients’ cultural values and daily habits. In a similar sense, it is not enough to inform smallholder farmers about the merits of fertiliser. Development agencies should also ensure that fertiliser is sold right after the harvest, when farm- ers have money, and not only shortly be- fore they re-sow in the lean season, when they normally lack cash. The World Bank experts emphasise the relevance of how expectations mark soci­ eties. It is very hard to fight corruption, for instance, once it has become entrenched in a collective mind set. If the paying and taking of bribes is considered normal, de- viation from the pattern is difficult – both for payers and takers of bribes. Changing destructive social attitudes is a huge chal- lenge, the report warns, and simple incen- tives plus rational reasoning will not do the job. In separate chapters, the report assess- es issues such as fighting poverty, child- hood development, health or climate change. One chapter discusses how group think and flawed theorising distort the work of development agencies. The World Bank wants them to “implement proce- dures” to mitigate such problems. The au- thors write that developmental interven- tions should be tested and fine-tuned in repeated trials before being scaled up. This is the way, they argue, to ensure that meas- ures prove most effective. In this regard, the report echos authors such as Abhijit Banerjee and Esther Duflo (2011), Ben Ra- malingam (2013) or David Booth (2014). After largely ignoring sociological and psychological arguments for dec- ades, the World Bank now pretends to be responding to recent research. In truth, it has been understood for a long time that the poor in particular depend on commu- nity support in times of crisis and thus resemble the homo-economicus model even less than the rich. The stance of the World Development Report thus suits technocrats who are defending a position of power. The shift in thinking is welcome nonetheless: better late than never.
