In the following article, Joseph Stiglitz argues that power rather than competition is a better starting point for analysing the working of capitalism. People’s rewards depend less on their marginal product than on their power over labour or capital (or lack of it).
As inequality has widened and concerns about it have grown, the competitive school, viewing individual returns in terms of marginal product, has become increasingly unable to explain how the economy works.
Thus the huge bonuses, often of millions of pounds per year, paid to many CEOs and other senior executives, are more a reflection of their power to set their bonuses, rather than of their contribution to their firms’ profitability. And these excessive rewards are not competed away.
Stiglitz examines how changes in technology and economic structure have led to the increase in power. Firms are more able to erect barriers to entry; network economies give advantages to incumbents; many firms, such as banks, are able to lobby governments to protect their market position; and many governments allow powerful vested interests to remain unchecked in the mistaken belief that market forces will provide the brakes on the accumulation and abuse of power. Monopoly profits persist and there is too little competition to erode them. Inequality deepens.
According to Stiglitz, the rationale for laissez-faire disappears if markets are based on entrenched power and exploitation.

Growing inequality of income and wealth is a common pattern throughout the world. In the boom years up to 2008, the rich got a lot richer, but at least those on low incomes generally saw modest rises in their incomes. Since 2008, however, the continually widening gap between rich and poor has seen the poor and many on middle incomes getting absolutely poorer.
The problem is particularly acute in the USA. Indeed, in his 2012 State of the Union address, President Obama said that it was the ‘defining issue of our time.’
No challenge is more urgent. No debate is more important. We can either settle for a country where a shrinking number of people do really well, while a growing number of Americans barely get by. Or we can restore an economy where everyone gets a fair shot, everyone does their fair share, and everyone plays by the same set of rules.
The good news for the poor in the USA is that at last their incomes have stopped falling, thanks to stronger economic growth. But their share of the growth in GDP is tiny.
As The Economist article states:
The main message is a grim one. Most of the growth is going to an extraordinarily small share of the population: 95% of the gains from the recovery have gone to the richest 1% of people, whose share of overall income is once again close to its highest level in a century. The most unequal country in the rich world is thus becoming even more so.
Apart from the ethical question of whether it is desirable for a society, already highly unequal, to become even more so, there is the question of whether this growth in inequality threatens economic recovery. Joseph Stiglitz argues that the rich have a low marginal propensity to consume and that this is threatening recovery.
Then there is the question of investment. Because most Americans have not seen any significant rise in incomes, it is easy for them to believe that the country cannot afford to invest more. And certainly it is difficult to persuade people that higher taxes are warranted to fund education, infrastructure or research.
The following articles consider the problem and its implications and look at various policy alternatives.

Happiness and unhappiness are central to economists’ analysis of consumer behaviour. If we define ‘utility’ as perceived happiness, standard consumer theory assumes that rational people will seek to maximise the excess of happiness over the costs of achieving it: i.e. will seek to maximise consumer surplus. In fact, this analysis can be traced back to the work of the utilitarians, Jeremy Bentham and John Stuart Mill. Bentham reffered to it as hedonic or felicific calculus (see also and also).
Now, of course, whether people actually behave in this way is an empirical question: one that behavioural and experimental economists have been investigating over a number of years. Nevertheless, it remains central to neoclassical analysis of ‘rational behaviour’.
But if happiness is central to a large part of economic analysis, how is happiness to be measured? At a micro level, this has proved problematic as it is virtually impossible to have inter-personal comparisons of utility. As a result, consumer theory uses indifference analysis, characteristics analysis, revealed preference and other approaches to analyse consumer demand.
But what about at the macro level? How is a nation’s happiness or well-being to be measured? There is general acceptance that GDP is a relatively poor proxy for national well-being and is more a measure of production. There have been various indices developed over the years (see, for example, Box 14.7 on ISEW in Economics, 7th edition) as alternatives to GDP. None has been adopted by governments, however, with the exception of a Gross National Happiness index in Bhutan.
Recently, however, there has been renewed interest in developing an index of well-being. In France, President Sarkozy commissioned two Nobel economists, Joseph Stiglitz and Amartya Sen, to examine the issues in developing such a measure. In the light of the Stiglitz/Sen report, David Cameron has asked the Office of National Statistics to measure the UK’s general well-being. The articles below look at the difficulties that could arise in producing an index of well-being, of meauring the elements and in using it for policy.

Until the credit crunch and crash of 2008/9, there appeared to be a degree of consensus amongst economists about how economies worked. Agents were generally assumed to be rational and markets generally worked to balance demand and supply at both a micro and a macro level. Although economies were subject to fluctuations associated with the business cycle, these had become relatively mild given the role of central banks in targeting inflation and the general belief that we had seen the end of boom and bust.
True, markets were not perfect. There were problems of monopoly power and externalities. Also information was not perfect. But asymmetries of information were generally felt to be relatively unimportant in the information age with easy access to market data through the internet.
Then it all went wrong. With the exception of a few economists, people were caught unawares by the credit crunch. There was too little understanding of the complexities of securitisation and the leveraged risk in these pyramids of debt built on small foundations. And there was too little regard paid to the potentially destructive power of speculation and herd behaviour.
So how should economists model what has been happening over the past three years? Do we simply need to go back to Keynesian economics, which emphasised the importance of aggregate demand and the ability of economies to settle at a high unemployment equilibrium? Can the persistence of high unemployment in the USA and elsewhere be put down to a lack of demand or is the explanation to be found in hysteresis: the persistence of a problem after the initial cause has disappeared? Can failures of markets be incorporated into standard microeconomics?
Or do we need a new paradigm: one that emphasises the behaviour of economic agents and examines how people act when there are information asymmetries? These are the questions that are examined in the podcast below. It is an interview with Nobel Prize winning economist, Joseph Stiglitz.
