The Nobel prize goes to Jean Tirole

Oct 13th 2014, 12:45 by C.R. | LONDON

AFTER last year's three-way split, this year's Sveriges Riksbank prize in

economic sciences in memory of Alfred Nobel goes to a single receipient, Jean

Tirole of Toulouse University in France (pictured). He has been awarded the

prize for his microeconomic research investigating how large firms should be

regulated in order to prevent consumers being damaged by their monopolistic

behaviour.

As the Royal Swedish Academy of Sciences notes on its website:

Jean Tirole is one of the most influential economists of our time. He has made

important theoretical research contributions in a number of areas, but most of

all he has clarified how to understand and regulate industries with a few

powerful firms.

Many industries are dominated by a small number of large firms or a single

monopoly. Left unregulated, such markets often produce socially undesirable

results prices higher than those motivated by costs, or unproductive firms that

survive by blocking the entry of new and more productive ones.

From the mid-1980s and onwards, Jean Tirole has breathed new life into research

on such market failures. His analysis of firms with market power provides a

unified theory with a strong bearing on central policy questions: how should

the government deal with mergers or cartels, and how should it regulate

monopolies?

Before Tirole, researchers and policymakers sought general principles for all

industries. They advocated simple policy rules, such as capping prices for

monopolists and prohibiting cooperation between competitors, while permitting

cooperation between firms with different positions in the value chain. Tirole

showed theoretically that such rules may work well in certain conditions, but

do more harm than good in others. Price caps can provide dominant firms with

strong motives to reduce costs a good thing for society but may also permit

excessive profits a bad thing for society. Cooperation on price setting within

a market is usually harmful, but cooperation regarding patent pools can benefit

everyone. The merger of a firm and its supplier may encourage innovation, but

may also distort competition.

The best regulation or competition policy should therefore be carefully adapted

to every industry's specific conditions. In a series of articles and books,

Jean Tirole has presented a general framework for designing such policies and

applied it to a number of industries, ranging from telecommunications to

banking. Drawing on these new insights, governments can better encourage

powerful firms to become more productive and, at the same time, prevent them

from harming competitors and customers.

Unlike some previous recipients, such as Robert Engle and Clive Granger in 2003

or Lars Peter Hansen in 2013, who won the prize for developing new econometric

methods few laymen can easily understand, Mr Tirole's research has direct

relevance to current policy issues. Most notably, his ideas of how to regulate

industries dominated by a single large firm are helping to produce strategies

for how to prevent Google from using its vast market share in the

internet-search business to behave as a monopoly. And as we argued back in

March, Mr Tirole's theories can also help us understand the impact on markets

of disruptive forces such as Uber, a taxi app that matches customers and

drivers. For those readers who want to read more about Jean Tirole's research
