Disciples of Keynes, who focus on aggregate demand, view any increase in household wealth as raising employment because they say it adds to consumer demand.

I'm old enough to remember in the 1930s and the 1940s when thrift, frugality, was considered an important virtue.

Statistical studies are all over the lot about the pluses and minuses of raising the minimum wage.

Unemployment determination in a modern economy was the main subject area of my research from the mid-1960s to the end of the 1970s and again from the mid-1980s to the early 1990s.

The level of dynamism is a matter of how fertile the country is in coming up with innovative ideas having prospects of profitability, how adept it is at identifying and nourishing the ideas with the best prospects, and how prepared it is in evaluating and trying out the new products and methods that are launched onto the market.

I started to think about what drives innovation and what its social significance might be. The next step was to think innovators are taking a leap into the unknown. That led me to the thought that it is also a source of fun and employee engagement.

After a major loss of dynamism in the 1960s, productivity growth rates began dropping in most countries, falling by half in the U.S. in the 1970s and more or less ceasing altogether in France, Germany and Britain in the late 1990s.

A nation's economy is more than its markets, tastes, technologies and property rights.

Well into the 20th century, scholars viewed economic advances as resulting from commercial innovations enabled by the discoveries of scientists - discoveries that come from outside the economy and out of the blue.
