Quite basic towards the start, but really insightful towards the end. I don't know much at all about economics and would recommend it to 'beginners'. Portes' other books are probably better for those more in the know. Some of my notes:
Workers have historically received about two thirds of the total value created by the economy (the 'labour share'). Since about 2008 however, this has decreased in many countries - we don't know whether this is temporary.
Monopolies don't foster innovation or decent prices because of the lack of competition. But too much competition can have a similar effect - the lack of profit most firms make can stymie innovation (as it requires upfront investment) and therefore prevent longer term reductions in costs to consumers.
On data and internet: "if you're not paying for the product, you are the product"
'The invisible hand' - this refers to the idea that, if markets work, then individuals rationally pursuing self-interest should maximise the value of what society produces. This is because of the price mechanism (supply and demand). But the counter to this is that markets don't work at all without government intervention (to establish property rights and enforced contracts).
companies limit risk: 'while capitalism may be all about taking risks, one of the key inventions that made modern capitalism possible does so by limiting risk.'
A 'bubble' is an episode where the market prices systematically deviate from those implied by publicly available information.
Burton Malkiel: "a blindfolded monkey throwing darts at a newspaper's financial pages could select a portfolio that would do just as well as one carefully selected by experts"
It's not so much the amount of debt that matters but its distribution - who owes what to whom.
There is no evidence to suggest that the financial crisis was caused or worsened by high levels of government debt, except in the case of Greece. The exceptionally low interest rates mean financing government borrowing has never been easier in UK. Most economists think it makes obvious sense for governments to borrow more to increase public investment and boost demand, but public and political fear of increasing public debt has so far blocked this route.
A major contradiction between capitalism and democracy is the former's principle that money determines access to power and resources while the latter's principle is one person one vote. In the US elected officials spend half their time fundraising and 9/10 winning candidates had the most money of those standing. A study found that the preferences of the average American have "a miniscule, near-zero, statistically non-significant effect" on political outcomes
Nationalisation became popular after WW2. The planning was essential to reconstruction. But the idea that nationalised industries, free from the whims of markets, could invest for the long term forgot the fact that they were instead subject to the whims of politicians who are also short term minded.
An early example of globalisation was 'triangular trade' - guns, gold and jewellery was shipped to Africa from Britain, slaves were shipped from Africa to the Caribbean, and cotton and tobacco went from the Caribbean to Britain.
The addition of hundreds of millions of lowpaid workers from China and other countries to the global economy (combined with lower communication and transport costs) has led to a sharp fall in global inequality alongside significant rises in inequality within countries - as poor countries' manual labourers get higher wages but developed countries' have wages pushed down
Unemployment is usually (these days) seen as the combination of factors:
there is always some frictional unemployment as jobs are destroyed and those workers search for a new job
There is also structural unemployment resulting from how markets function (or fail to do so). This can be the result of over-generous benefits, but there's little evidence of that in most countries. More likely it's due to workers not having the skills they need, or discrimination, or hiring and firing rules making it risky for employers to take on new staff
"As long as we live in a predominantly capitalist economy, culture will be shaped by the market." Examples being Beyonce, star wars
There is little evidence that immigrants push down wages for native workers - several UK studies have failed to find any significant impact. Even large influxes like refugees to Israel in 1990s or recently to Turkey have had only a small effect.
Immigration *is* associated with higher Innovation, international trade and knowledge transfer (especially in high-tech industries)
Technological change.is happening faster now - it took 40 years for landlines to reach half of Americans, bit only 10 for mobile.
Global warming is the biggest example of the economic problem, an 'externality'. This is where someone uses a free resource in a way that imposes a cost on others. A carbon tax or similar would mean we use less and entrepreneurs would have an incentive to come up with alternatives.
