7-15 Free exchange / Nice work if you can get out



Free exchange / Nice work if you can get out

Discussion points
How do you evaluate your “substitution effect” ?
Do you think of your work as “exploit” ?

The author is talking about the change of the relationship between money and leisure by contrasting 19th century’s situation and today’s one. In the 19th century, as a British drama “Downtown abbey” showed, rich people enjoyed their leisure time almost every day while poor people worked hard and enjoyed less leisure. In today’s advanced economy however, several surveys show that overall working hours of the rich have been longer than the poor.

There are several explanations to this shift. First one is what some economists call the “substitution effect”. Higher wages makes leisure more expensive: if people take time off they give up more money. Furthermore, the “winner-takes-all” nature of modern economies may amplify the substitution effect. In the globalised market where good ideas and innovations are highly valuable, the more skilled workers could get more money.

Secondly, the author points out that the status of work and leisure in rich world has changed today so rich people tends to concentrate on their work even if they are paid enough. Work in advanced economies has become more knowledge-incentive and intellectual, whereas most jobs in 19th century were really dull ones. The writer of this column uses Veblen’s theory as an explanation. Thorstein Veblen, an American economist in 19th century argued that leisure class people who do not engaged in industry were not idle. Instead of working in industry, leisure class people engaged in what he called “exploit”: challenging and creative activities such as writhing, philanthropy and debating. The columnist states that in rich society, more people than ever can enjoy “exploit” at their office so the people can get pleasure from their work instead of leisure time in which they used to seek their satisfaction.

Lastly, the author picks up the situation of less educated workers. As low-skill and manual jobs are shrinking and as information technology are opening up a vast world of high quality and cheap home entertainment, they do not need to work as long to enjoy a reasonably satisfying leisure.

For these reasons, the columnist points out that rich people now have less leisure than the poor.

7-12 Rise of the robots


Rise of the robots
Prepare for a robot invasion. It will challenge the way people think about technology.  
from March 29th 2014 Leaders

How will robots change the way people think about technology?
Technological development can make robots not just as workers and partners but also actors that can collect information and make their decisions autonomy. When our society accepts such robots, there should be problems we have to discuss. If an accident in which robots (driverless cars for example) take part happens, who is responsible for it? If programming is fault, programmers should be blamed but what if the accident happens by the result of robot’s own decision? We have to rethink our law and regulation to be suitable for robots society where robots can be law entities. 

Summary of the article
Robots came into the world as a literacy device in science fictions and movies. But since moving from the page and screen to real life, robots have been a mild disappointment. They do some things humans cannot do themselves but still unreliable and pretty stupid.

That seems about to change given by the exponential growth in the power of silicon chips, digital sensors and high bandwidth communications. And there are other three factors (R&D, investment and imagination) into play.

R&D: New shared standard and accumulated know-how makes R&D easier.
Investment: Tech giants and venture capitalists put their money in robotic startups.
Imagination: Clever robotics application can be found in some sectors.

As consumers and citizens, people will benefit greatly from the rise of the robots. Almost all the manufacturing and services might be done by robots, so whether humanity will find new ways of using its labor or it will be forced to have leisure is worried debate among economists.


Robots can do their jobs animatedly and they also can be inhabited alongside humans, fulfilling all sorts of needs. They provoke questions such as war and drones, emotions caused by a machine and the value of labor. Robots can serve not just as workers and partners but also providers of new perspective.
