Economics is about choice – and choices occur in all parts of our lives. One area is personal relationships. Are we making the best of our relationships with family, friends and sexual partners? Increasingly economists are examining human behaviour in such contexts and asking what factors determine our decisions and whether such decisions are rational.
A recent book looks at the economics of marriage and goes under the title of ‘Spousonomics‘. Its authors, Paula Szuchman and Jenny Anderson, use economics “to master love, marriage and dirty dishes”. As they say:
Every marriage is its own little economy, a business of two with a finite number of resources that need to be allocated efficiently.
They look at ways in which such resources can be allocated efficiently. They also look at apparently irrational behaviour and seek to explain it in terms of various ‘failures’ (akin to market failures). They also examine how these failures can be rectified to improve relationships.
So is this economics stepping on the toes of relationship counsellors and psychologists? Or is this the legitimate domain of economists seeking to understand how to optimise in the context of scarce resources – including time and patience?

GDP (or Gross Domestic Product) measures the value of output produced within a country over a 12-month period. It is this figure which we use to see how much the economy is growing (or shrinking). We can also look at how much different sectors contribute towards this figure. Over the past few decades, there has been a significant change in the output of different sectors, as a percentage of GDP, within the UK economy. In particular, the contribution of manufacturing has diminished, while services have grown rapidly.
However, there is one specific area that is making a growing contribution towards UK GDP and is expected to see acceleration in its growth rate by some 10% annually over the next few years: the internet. Although the internet is not an economic sector, the Boston Consulting Group (BCG) said that if it was, it would be the UK’s fifth largest sector and according to a report by Google, it is worth approximately £100 billion per year to the UK economy. Furthermore, it is an area in which the UK is one of the leading exporters. The emergence of the internet has transformed industries and individual businesses and the trend looks set to continue. The report by Google found that some 31 million adults bought goods and services online over the past year, spending some £50 billion.
What are the benefits for businesses of internet shopping and does it have an impact on the retail outlets on Britain’s highstreets? The answer is undoubtedly yes, but is it good or bad? What does the emergence of this new ‘sector’ mean for the UK economy?
