Economics in Action

In the third of a series of interviews from the Royal Economic Society annual conference 2007, Romesh Vaitilingam talks to Stephen Drinkwater about self-employment among Britain’s Asian community.

The typical Asian working age male is now younger, better educated and more likely to be UK-born than his parents generation were. According to research by Ken Clark and Stephen Drinkwater, each of these factors contributes to lower rates of self-employment, particularly among men of Indian and Chinese ethnicity. This suggests greater assimilation of these groups into the UK labour market and education system.

But the study, presented to the Royal Economic Society’s 2007 annual conference at the University of Warwick, also finds relatively stable rates of self-employment among Pakistani and Bangladeshi men. It seems likely that discrimination in paid employment against these groups is keeping them in self-employment, working long hours in relatively poorly rewarded sectors such as catering and taxi-driving

Britain’s national minimum wage has not only raised the pay of low-paid employees. It has also led to a reduction in the rate of these employees absence through sickness  and hence improved their productivity. That is the finding of new research by Marco Ercolani and Martin Robson, presented at the Royal Economic Society Conference 2007. This effect might help to explain why the introduction of the minimum wage was greeted with apparent equanimity by many employers.

Employee sickness absence is widely recognised as a major problem for the economy. In recent years, for example, it has been calculated that the direct costs of sickness absence in terms of the value of lost output amount to over £11 billion per annum; around 1% of the country’ annual GDP.

On top of this, there are the indirect costs such as the loss of employee morale among those required to cover for absent colleagues. While many instances of employee sickness absence represent genuine cases of ill health, a significant proportion almost certainly does not. (more…)

Wages tend to rise in British firms taken over by US multinationals: on average, in the two years after an acquisition, skilled workers see their earnings increase by 8% while unskilled workers pay goes up by 13%. But there are no such effects for takeovers by multinationals from continental European Union countries.

These are the findings of new research by Holger GÃrg and Sourafel Girma, which explores whether acquisitions of British companies by foreign multinationals are a threat to domestic labour.

Their study, presented at the Royal Economic Society’s 2006 Annual Conference at the University of Nottingham, looks at one aspect of this topical question: whether wages change in firms after they have been taken over by foreign firms.

There is a strong link between the earnings of fathers and sons, according to new research by Professor Robin Naylor and colleagues. What’s more, the likelihood of a son having earnings similar to his father’s is greater for those born into particularly rich or poor backgrounds. And especially in the UK and the United States, the sons of earners in the top 20% are very unlikely to end up in the bottom 20% of earners.

The study, presented at the Royal Economic Society’s 2006 Annual Conference at the University of Nottingham, examines how intergenerational mobility compares between the UK, the United States and the Nordic countries of Norway, Denmark, Sweden and Finland. The main results are that:

Despite the commonly-perceived view of the US as an open society with ready opportunities for individuals to rise from poverty to affluence (from rags to riches), the evidence shows that the opposite is true. On average, a son’s earnings are more closely related to his father’s earnings in the United States than in any of the other countries.

In the UK, the connection between sons earnings and fathers earnings is weaker than in the United States, but stronger than in the Nordic countries. There is substantial earnings persistence across the generations in all countries.

This is the title of a research paper by economists Lena Edlund and Evelyn Korn, in which they consider the relative appeal of marriage and prostitution for women, and (closely linked) the relative appeal of wives and prostitutes for men.

Michael Noer in Forbes magazine shows wittily that the economic perspective on marriage is bleakly unromantic, but admits the point of the research is not to illuminate romantic feelings (for which we already have a culture’s worth of art and poetry) but to answer a specific question, namely, “Why do prostitutes earn so much money?” Is it compensation for the violence and disease which they are exposed to, or compensation for the fact that no-one wants to marry a prostitute?

Found via the book Economics Uncut: A Complete Guide to Life, Death and Misadventure, edited by Simon Bowmaker, which has many examples of economic research into topics like drugs, crime, abortion and gambling and includes Edlund and Korn’s original paper.

The Economist devotes 15 pages to the coming battle for talented employees. Many firms have gone as far as they can with automation and streamlining, so further improvements in productivity have to come on the human side, meaning their ability to recruit and keep bright, talented staff. While manual workers are increasingly replaced by automation, knowledge workers who can manage people and resources creatively and profitably will be increasingly in demand. As the workforce ages and jobs become more complex, competition for the best individuals will heat up.

You might be reading this as a young adult, considering how you will be earning money in the first half of the 21st Century. You might conclude that it is important to develop and prove your own abilities with a degree, especially in a course that involves numeracy and problem-solving. Far be it from WhyStudyEconomics to suggest a subject…
