The belief that immigrants would ruin the employment market is unfounded, says economics professor Li Jingkui. With bold and ambitious entrepreneurial spirits, immigrants are more likely to be “job creators”, rather than “job takers”, while the resulting increase in demand for goods and services even supports economic growth.

Despite a record number of graduates entering the job market this year, China is seeing a shortage of skilled tradesmen, especially for the manufacturing industry. Chinese economics professor Li Jingkui believes that the main reason for the talent demand gap is China’s education system, which is driven by remnants of the backward ideology of the ancient feudal society.

Over the past three decades, China has implemented and revised its labour regulations in an effort to progress its market economy. Despite the strengthening of labour protection, young migrant workers have fallen through the cracks. Chinese economics professor Li Jingkui believes that the labour reforms have led to the social phenomenon of “Sanhe legends” — youths who are caught in an employment cycle characterised by poor working conditions, low wages and a lack of stability.

One may be tempted to assume that monogamy is the ideal that humans aspire to, but this is not the case, says Chinese economics professor Li Jingkui. He explains why different marriage systems were devised to maximise economic benefits.

Li Jingkui explains that having children is very much an economic decision with hard choices involved, particularly for women. Research has shown that women’s chances of gaining employment after bearing their first child fall by 6.6%, and by another 9.3% after the second child. The government believes that an extended maternity leave policy will aid women and increase the nation’s fertility rate, but the reality may be much to the contrary.

While some businessmen have good intentions in offering goods and services at lower prices, they could also be “spoiling the market” and making it harder for others to make a living. Such actions may invite backlash, whether in village scuffles, or writ large, protests and anti-dumping measures between countries. China, the world’s factory, has borne the brunt of such pushback. Industries in other countries are affected, as capital moves freely between borders but labour stays in place. Those who feel they are losing out may hold grudges and end up dealing a big blow to society.

Perhaps the theory of the survival of the fittest can help to explain the opposite gender imbalance in rural-urban China. Aspirant males and females head to cities in search of better prospects; the latter, with the added aim of better marriage prospects, invariably outnumber the men. Of the males that stay or return, there is the heavy bride price to pay to win the hand of a lady among the smaller pool of women left in the rural areas. This modern malaise is something no provincial policy can easily solve, says economist Li Jingkui.

A family stroll down a food alley has Chinese economist Li Jingkui teaching the Coase theorem while holding his breath and fleeing a luosifen stall and its pungent smells. If rights of stallholders are defined and transaction costs are low, then the optimal value of resources in society will be realised. That is, either the luosifen moves away under some compensation from his neighbour or it stays put and his neighbours cope with the negative externalities this presents.

The Big Mac index as an informal gauge of the economic standards and consumption capacities of countries is well known. But actually, there’s also the pickle index, the lipstick index, and the ultimate indicator from everyday life — the regional food flavours index. What do the saltier, bold-flavoured food in regions like Hunan, Jiangxi and Shandong, and the clean, light flavours of Jiangsu say about the relative states of their regional economies?
