📖 I’m 10% done reading Economy, Society, and Public Policy by CORE Team

Finished chapter one. I like that this text has so many linked resources, but some of the links to the sister texts make me think I’d be getting a deeper and more technical understanding by reading them instead of this more introductory text. Still, this has some tremendous value even as a refresher.

Government bodies also tend to be more limited in their capacity to expand if successful, and are usually protected from failure if they perform poorly.

They can expand in different ways however. Think about the expansion of empires of Egypt, Rome, and the Mongols in the 12th Century. What caused them to cease growing and decrease? What allowed them to keep increasing?

Capitalism is an economic system that can combine centralization with decentralization.

How can we analogize this with the decentralization of the web and its economy?

Market competition provides a mechanism for weeding out those who underperform.

Note how this has failed in the current guilded age of the United States where it is possible for things to be “too big to fail”.

First, because capital goods do not fall from the sky: all countries that have successfully moved from poverty to affluence have done so, of necessity, by accumulating large amounts of capital. We will also see that a crucial feature of capitalism is who owns and controls the capital goods in an economy.

Yet some things that we value are not private property—for example, the air we breathe and most of the knowledge we use cannot be owned, bought, or sold.

We should be sceptical when anyone claims that something complex (capitalism) ‘causes’ something else (increased living standards, technological improvement, a networked world, or environmental challenges), just because we can see there is a correlation.

Figure 1.16 Graph with y-axis that jumps around in scale

Note the dramatic inconsistency of the scale on the left hand side. What is going on here?

Firms should not be owned and managed by people who survive because of their connections to government or their privileged birth: Capitalism is dynamic when owners or managers succeed because they are good at delivering high-quality goods and services at a competitive price. This is more likely to be a failure when the other two factors above are not working well.

Here is where we’re likely to fail in the United States by following the example of Donald Trump, who ostensibly has survived solely off the wealth of his father’s dwindling empire. With that empire gone, he’s now turning to creating wealth by associating with the government. We should carefully follow where this potentially leads the country.

In some, their spending on goods and services as well as on transfers like unemployment benefits and pensions, accounts for more than half of GDP.

What is the Government’s proportion of the US GDP presently?

Read sections 1.0-1.3. I’m loving the graphs, charts, videos, and supplementary interactive material they’re including in the book. It’s completely fascinating and quite a different reading experience on a computer versus either paper or e-reader.

Having immediate access to data like this make for a more interesting Economics experience.

But some have taller skyscrapers at the back, meaning a greater disparity between the top 10% and the rest of the population, whereas others have a less steep profile.

It might be more interesting if the top decile in each country were broken into tenths to show the even more severe disparities. I suspect that some of the height differences would be even more drastic if we could see the top 1% or even the top 0.1% on these graphs.

A thousand years ago, the world was flat, economically speaking.

I don’t think we have to go back even this far. If I recall correctly, even 150 years ago the vast majority of the world’s population were subsistence farmers. It’s only been since the 20th century and the increasing spread of the industrial revolution that the situation has changed:

Even England remained primarily an agrarian country like all tributary societies for the previous 4,000 years, with ca. 50 percent of its population employed in agriculture as late as 1759.

If you have never seen an ice-hockey stick (or experienced ice hockey) this shape is why we call these figures ‘hockey-stick curves’.

I’m glad they’ve included an image of a hockey stick to provide the context here, but I’ve always thought of it rotated so that the blade was on the ground and the sharp angle of the handle itself indicated the exponential growth curve!

Read How to Calculate and Use Purchasing Power Parity – PPP: Why Does a Big Mac Cost a Lot Less in China? (The Balance)
Purchasing power parity is a theory that says prices of goods between countries should equalize over time. Formula, how to use, and examples.

After the war, the Swedish economist Gustav Cassel suggested multiplying each currency’s pre-war value by its inflation rate to get the new parity. That formed the basis for today’s PPP.

Why We Don’t Live in a PPP World
PPP depends on the law of one price. That states that once the difference in exchange rates is accounted for, then everything would cost the same.
That’s not true in the real world for four reasons. First, there are differences in transportation costs, taxes, and tariffs. These costs will raise prices in a country. Countries with many trade agreements will have lower prices because they have fewer tariffs. Socialist countries will have higher costs because they have more taxes. 
A second reason is that some things, like real estate and haircuts, can’t be shipped. Only ultra-wealthy global travelers can compare the prices of homes in New York to those in London. 
A third reason is that not everyone has the same access to international trade. For example, someone in rural China can’t compare the prices of oxen sold throughout the world. But Amazon and other online retailers are providing more real purchasing power parity to even rural dwellers.
A fourth reason is that import costs are subject to exchange rate fluctuations. For example, when the U.S. dollar weakens, then Americans pay more for imports.
