The World’s Most Famous Case of Deflation (Part 1 of 2)
The Great Depression was the most severe economic depression ever experienced by the Western world.
It was during this troubled time that the world’s most famous case of deflation also happened. The resulting aftermath was so bad that economic policy since has been chiefly designed to prevent deflation at all costs.
Setting the Stage
The transition from wartime to peacetime created a bumpy economic road after World War I.
Growth has hard to come by in the first years after the war, and by 1920-21 the economy fell into a brief deflationary depression. Prices dropped -18%, and unemployment jumped up to 11.7% in 1921.
However, the troubles wouldn’t last. During the “Roaring Twenties”, economic growth picked up as the new technologies like the automobile, household appliances, and other mass-produced products led to a vibrant consumer culture and growth in the economy.
More than half of the automobiles in the nation were sold on credit by the end of the 1920s. Consumer debt more than doubled during the decade.
While GDP growth during this period was extremely strong, the Roaring Twenties also had a dark side. Income inequality during this era was the highest in American history. By 1929, the income of the top 1% had increased by 75%. Income for the rest of people (99%) increased by only 9%.
The Roaring Twenties ended with a bang. On Black Thursday (Oct 24, 1929), the Dow Jones Industrial Average plunged 11% at the open in very heavy volume, precipitating the Wall Street crash of 1929 and the subsequent Great Depression of the 1930s.
The Cause of the Great Depression
Economists continue to debate to this day on the cause of the Great Depression. Here’s perspectives from three different economic schools:
John Maynard Keynes saw the causes of the Great Depression hinge upon a lack of aggregate demand. This later became the subject of his most influential work, The General Theory of Employment, Interest, and Money, which was published in 1936.
Keynes argued that the solution was to stimulate the economy through some combination of two approaches:
1. A reduction in interest rates (monetary policy), and
2. Government investment in infrastructure (fiscal policy).
“The difficulty lies not so much in developing new ideas as in escaping from old ones.” – John Maynard Keynes
Monetarists such as Milton Friedman viewed the cause of the Great Depression as a fall in the money supply.
Friedman and Schwartz argue that people wanted to hold more money than the Federal Reserve was supplying. As a result, people hoarded money by consuming less. This caused a contraction in employment and production since prices were not flexible enough to immediately fall.
“The Great Depression, like most other periods of severe unemployment, was produced by government mismanagement rather than by any inherent instability of the private economy.” ― Milton Friedman
Austrian economists argue that the Great Depression was the inevitable outcome of the monetary policies of the Federal Reserve during the 1920s.
In their opinion, the central bank’s policy was an “easy credit policy” which led to an unsustainable credit-driven boom.
“Any increase in the relative size of government in the economy, therefore, shifts the societal consumption-investment ratio in favor of consumption, and prolongs the depression.” – Murray Rothbard
The Great Depression and Deflation
Between 1929 and 1932, worldwide GDP fell by an estimated 15%.
Personal income, tax revenue, profits and prices plunged. International trade fell by more than 50%. Unemployment in the U.S. rose to 25% and in some countries rose as high as 33%.
These statistics were only the tip of the iceberg. Learn about the full effects, the stories, and the recovery from the Great Depression in Part 2.
About the Money Project
The Money Project aims to use intuitive visualizations to explore ideas around the very concept of money itself. Founded in 2015 by Visual Capitalist and Texas Precious Metals, the Money Project will look at the evolving nature of money, and will try to answer the difficult questions that prevent us from truly understanding the role that money plays in finance, investments, and accumulating wealth.
The World’s Biggest Real Estate Bubbles in 2021
According to UBS, there are nine real estate markets that are in bubble territory with prices rising to unsustainable levels.
Ranked: The World’s Biggest Real Estate Bubbles in 2021
Identifying real estate bubbles is a tricky business. After all, even though many of us “know a bubble when we see it”, we don’t have tangible proof of a bubble until it actually bursts.
And by then, it’s too late.
The map above, based on data from the Real Estate Bubble Index by UBS, serves as an early warning system, evaluating 25 global cities and scoring them based on their bubble risk.
Reading the Signs
Bubbles are hard to distinguish in real-time as investors must judge whether a market’s pricing accurately reflects what will happen in the future. Even so, there are some signs to watch out for.
As one example, a decoupling of prices from local incomes and rents is a common red flag. As well, imbalances in the real economy, such as excessive construction activity and lending can signal a bubble in the making.
With this in mind, which global markets are exhibiting the most bubble risk?
The Geography of Real Estate Bubbles
Europe is home to a number of cities that have extreme bubble risk, with Frankfurt topping the list this year. Germany’s financial hub has seen real home prices rise by 10% per year on average since 2016—the highest rate of all cities evaluated.
Two Canadian cities also find themselves in bubble territory: Toronto and Vancouver. In the former, nearly 30% of purchases in 2021 went to buyers with multiple properties, showing that real estate investment is alive and well. Despite efforts to cool down these hot urban markets, Canadian markets have rebounded and continued their march upward. In fact, over the past three decades, residential home prices in Canada grew at the fastest rates in the G7.
Despite civil unrest and unease over new policies, Hong Kong still has the second highest score in this index. Meanwhile, Dubai is listed as “undervalued” and is the only city in the index with a negative score. Residential prices have trended down for the past six years and are now down nearly 40% from 2014 levels.
Note: The Real Estate Bubble Index does not currently include cities in Mainland China.
Trending Ever Upward
Overheated markets are nothing new, though the COVID-19 pandemic has changed the dynamic of real estate markets.
For years, house price appreciation in city centers was all but guaranteed as construction boomed and people were eager to live an urban lifestyle. Remote work options and office downsizing is changing the value equation for many, and as a result, housing prices in non-urban areas increased faster than in cities for the first time since the 1990s.
Even so, these changing priorities haven’t deflated the real estate market in the world’s global cities. Below are growth rates for 2021 so far, and how that compares to the last five years.
Overall, prices have been trending upward almost everywhere. All but four of the cities above—Milan, Paris, New York, and San Francisco—have had positive growth year-on-year.
Even as real estate bubbles continue to grow, there is an element of uncertainty. Debt-to-income ratios continue to rise, and lending standards, which were relaxed during the pandemic, are tightening once again. Add in the societal shifts occurring right now, and predicting the future of these markets becomes more difficult.
In the short term, we may see what UBS calls “the era of urban outperformance” come to an end.
Mapped: Distribution of Global GDP by Region
Where does the world’s economic activity take place? This cartogram shows the $94 trillion global economy divided into 1,000 hexagons.
Mapped: The Distribution of Global GDP by Region
Gross domestic product (GDP) measures the value of goods and services that an economy produces in a given year, but in a global context, it is typically shown using country-level data.
As a result, we don’t often get to see the nuances of the global economy, such as how much specific regions and metro areas contribute to global GDP.
In these cartograms, global GDP has been normalized to a base number of 1,000 in order to show a more regional breakdown of economic activity. Created by Reddit user /BerryBlue_Blueberry, the two maps show the distribution in different ways: by nominal GDP and by GDP adjusted for purchasing power parity (PPP).
Before diving in, let us give you some context on how these maps were designed. Each hexagon on the two maps represents 0.1% of the world’s overall GDP.
The number below each region, country or metropolitan area represents the number of hexagons covered by that entity. So in the nominal GDP map, the state of New York represents 20 hexagons (i.e. 2.0% of global GDP), while Munich’s metro area is 3 hexagons (0.3%).
Countries are further broken down based on size. Countries that make up more than 0.95% of global GDP are broken down into subdivisions, while countries that are smaller than 0.1% of GDP are grouped together. Metro areas that account for over 0.25% of global GDP are featured.
Finally, it should be noted that to account for some outdated subdivision participation data, the map creator calculated 2021 estimates for this using the formula: national GDP (2021) x % of subdivision participation (2017-2020).
Nominal vs. PPP
The above map is using nominal data, while the below map accounts for differences in purchasing power (PPP).
Adjusting for PPP takes into account the relative value of currencies and purchasing power in countries around the world. For example, $100 (or its exchange equivalent in Indian rupees) is generally going to be able to buy more in India than it is in the United States.
This is because goods and services are cheaper in India, meaning you can actually purchase more there for the same amount of money.
Anomalies in Global GDP Distribution
Breaking down global GDP distribution into cartograms highlights some interesting anomalies worth considering:
- North America, Europe, and East Asia, with a combined GDP of nearly $75 trillion, make up 80% of the world’s GDP in nominal terms.
- The U.S. State of California accounts for 3.7% of the world’s GDP by itself, which ranks higher than the United Kingdom’s total contribution of 3.3%.
- Canada as a country accounts for 2% of the world’s GDP, which is comparable to the GDP contribution of the Greater Tokyo Area at 2.2%.
- With a GDP of $3 trillion, India’s contribution overshadows the GDP of the whole African continent ($2.6 trillion).
- This visualization highlights the economic might of cities better than a conventional map. One standout example of this is in Ontario, Canada. The Greater Toronto Area completely eclipses the economy of the rest of the province.
Inequality of GDP Distribution
The fact that certain countries generate most of the world’s economic output is reflected in the above cartograms, which resize countries or regions accordingly.
Compared to wealthier nations, emerging economies still account for just a tiny sliver of the pie.
India, for example, accounts for 3.2% of global GDP in nominal terms, even though it contains 17.8% of the world’s population.
That’s why on the nominal map, India is about the same size as France, the United Kingdom, or Japan’s two largest metro areas (Tokyo and Osaka-Kobe)—but of course, these wealthier places have a far higher GDP per capita.
