| Ronald Coase, who has died aged 102, won the Nobel prize for economic sciences in 1991 for his work in discovering and clarifying the importance of transaction costs in the functioning of the economy. His substantial contribution to economics spanned eight decades. Coase challenged the idea that "externality problems" – in which the costs of an action are felt by those who are not party to it – necessitated government intervention in the form of taxes or regulation. | Ronald Coase, who has died aged 102, won the Nobel prize for economic sciences in 1991 for his work in discovering and clarifying the importance of transaction costs in the functioning of the economy.

| Well-defined property rights and low transaction costs could allow individuals to resolve problems themselves through voluntary exchange in a free market. If you do not like the fact that your neighbour plays his music too loudly, or allows his dogs to roam around your garden, perhaps you should pay him to stop. Or, if your neighbour strongly desires to continue to act in this way, perhaps he should pay you to allow him to do so. State intervention to solve these disputes – in the form of taxes, regulations and prohibitions – should not be wholly ruled out, but neither should they be considered the constant default option. | Well-defined property rights and low transaction costs could allow individuals to resolve problems themselves through voluntary exchange in a free market.

| Coase was born in Willesden, northwest London. His father worked for the post office, as had his mother before their marriage. After attending Kilburn grammar school on a scholarship, he studied at the London School of Economics, receiving a bachelor of commerce degree and joining its staff in 1935. In 1937, he married Marion Hartung, from Chicago. | Coase was born in Willesden, northwest London. His father worked for the post office, as had his mother before their marriage.

| In the same year, Coase published his influential essay The Nature of the Firm. Coase understood that the institutional and legal framework of a society was vital to appreciating how economic activity would be conducted. In the entirely theoretical world of a perfectly functioning market, with no transaction costs and everyone in possession of correct information, we would all be self-employed and continually entering into new contracts with one another, seeing our salaries fall and rise with every passing minute depending on our productivity. | In the same year, Coase published his influential essay The Nature of the Firm.

| In the real world, of course, companies face the prohibitive costs of continually working out with whom to do business and which goods and services they need to obtain (transaction costs). Coase posited the theory that the amount businesses could grow by depended on how they coped with internalising these costs and how they minimised entrepreneurial errors. He correctly predicted that tech nological developments, including cheaper, faster transport and more cost-effective communication, would lead to companies expanding in size. | In the real world, of course, companies face the prohibitive costs of continually working out with whom to do business and which goods and services they need to obtain (transaction costs).

| After moving to the US in 1951, Coase worked at the University of Buffalo and the University of Virginia. In 1964 he took a position at the University of Chicago, where he became editor of the Journal of Law and Economics. It was in this publication in 1960 that Coase published his most famous piece of work, The Problem of Social Cost, which gave rise to the "Coase theorem", as his friend and colleague George Stigler dubbed it. He used the example of two farmers facing a situation in which one man's cattle strays on to his neighbour's field of crops. If the cost of restraining the cattle, ie the rancher paying to erect a fence, is less than the cost of the damage to the crops, this will be achieved irrespective of whether this is paid for by the arable farmer or the cattle rancher. Who picks up the bill will simply be determined by the allocation of property rights. The Coase theorem had practical applicability in the debate about the rights over the radio spectrum in 1960s America. | After moving to the US in 1951, Coase worked at the University of Buffalo and the University of Virginia.

| His work in this area continues to have relevance today. In the debate over climate change, Coase's work provides the intellectual basis for favouring a trading scheme of carbon credits, rather than the state imposition of anti-emissions regulations. Similarly, his work informs the approach to auctioning the airwaves for mobile telecommunications – just as it did for radio half a century ago. | His work in this area continues to have relevance today.

| Throughout his career, Coase believed that economists were too prone to theorising about what might occur in an abstract and imaginary world. Indeed, he worried about the practical application of the Coase theorem itself. He is rightly considered to be the father of institutional economics, and the academic field of "law and economics" would not exist without him. | Throughout his career, Coase believed that economists were too prone to theorising about what might occur in an abstract and imaginary world.

| In the last years of his life, Coase turned his attention to the emergence of capitalism in China. His final great work in 2012, co-authored with Ning Wang, was How China Became Capitalist. Asked by a friend and colleague whether he thought the Chinese would be particularly receptive to his economic ideas, Coase quipped: "Not necessarily, but there are a lot of them." | In the last years of his life, Coase turned his attention to the emergence of capitalism in China.

| Coase and Wang argued that China's move towards capitalism had essentially been an accidental byproduct of an attempt to bring about perfect socialism and sounded a warning that a continuing desire for economic and political control on the part of the Chinese authorities could derail the country's long-term potential for growth. | Coase and Wang argued that China's move towards capitalism had essentially been an accidental byproduct of an attempt to bring about perfect socialism and sounded a warning that a continuing desire for economic and political control on the part of the Chinese authorities could derail the country's long-term potential for growth. |
| Considered by his friends to be a generous and modest man despite his enormous academic achievements, Coase conceded that he had originally expected it to take a century or more for China to become capitalist. Asked why an economic legend such as himself could be so wrong about a matter of such global significance, Coase replied: "I've been wrong so often, I don't find it extraordinary at all." | Considered by his friends to be a generous and modest man despite his enormous academic achievements, Coase conceded that he had originally expected it to take a century or more for China to become capitalist.

| He will, however, be remembered across a wide range of academic disciplines as a brilliantly insightful man who managed to get so many things right and who could explain real world economic behaviour with incision and clarity. | He will, however, be remembered across a wide range of academic disciplines as a brilliantly insightful man who managed to get so many things right and who could explain real world economic behaviour with incision and clarity. |
