NOTES ON COVID:

ETFs earnt more than everyone then Active management (which for a while has not been earning
this much and certainly not more than Quant firms) Quant firms lost instead because they did not
take into account the possibility of a pandemic because they did not have data to take into account
about such an event.

Economic degrowth + recession but this not due to financial crisis  not a Minsky moment.



VIDEOS 1 ON MINSKY

Unit has assets and liabilities (=cash flows over each year)

 assets generate profits allocated in different ways according to the liability’s structure

Liability structure = a prior commitment of expected future incomes

- If unit can cover both interest + principal debt payments (= can fully validate its debts out of
current income with a margin of safety) = “hedge unit”

When economy dominated by hedge financing  you get an interest rate pattern: where short term
interest rates = substantially lower than long term interest rates

Keynes  pointed out there was a constitutional bias = lenders prefer to lend short while buyers
prefer to borrow long.

 payments includes both payment of interest + of principal
It is possible to roll over (=borrow again) the debts to keep financing the project you want to
invest in

Secrets for a well ordered financial system:  if your profit flows are good + they are expected to
remain good  you have no trouble rolling over debt (sometimes its formalized)

Rolling over finance = speculative

- In a long term hedge contract = you know the interest payments and you know the
refinancing problem
- In a speculative one = interest payments may go up or down on you as the market changes
+ you may find that liquidity preferences of the lender has affected how they are willing to
deal with you from time to time
- Ponzi finance = when you borrow to pay interest (Mexico, Brazil) = debt growing in a very
inefficient way  you are not getting investment nor consumer goods = you are just getting
closer to the next crisis

Ponzi financing = will occur when a debt burden (=short term debt mainly) is confronted with a drop
in profits or huge rise in interest rate

Ponzi finance = leads to cutting off areas from being externally financed + weakens the financing
ability of institutions because: it decreases the institutions’ profits and available funds

US economy consists of: (1) a system of borrowing and lending + (2) a basis of margins of safety.

2 margins of safety:

, - One is = cash flow margin
- Other = equity margin

When stock market collapses  equity margin of organizations can disappear, even though the cash
flow margin remains  the class or quality of borrowers disappears.

The market valuation of a company is important  because it is = the excess of their total value of
assets over their debts (as the market values it)

 so: a booming stock market is = increasing perceived margins of safety

 a collapsing stock market = diminishes it

Financial Instability Hypothesis = in normal functioning of an economy when: economy is doing well
+ liability’s structure predominantly hedge  the interest rate structure = is such that it is cheaper
to finance short-term than long-term + those who can make the arrangements for financing + re-
financing will shift their liability structure  and this continues until the margins is eaten up = means
higher short rates relative to long rates (long-rate being the market determined rate really).

 and then if you have rising interest rates + short term finance  you form good expectation
about the economy + develop financial structures where any drop in income or rise in interest rates
will transform some firms to Ponzi financing.

 when there are: firms become Ponzi  bankruptcy will occur affecting the liquidity preferences
of lenders + borrowers  leading to collapse

SO: = endogenous process based upon how financial markets behave + how profit seeking portfolio
managers + bankers + businesses behave.

There are agents operating for profits + agents who manage portfolios that need risk + uncertainty
valuation which are unfortunately miopic with regards to the past + imperfect with regards to the
future  therefore a capitalist economy = is subject to booms +busts.

VIDEO 2 ON MINSKY

Minsky moment = when a market fails or falls into crisis after an extended period of market
speculation r unsustainable growth.

A Minsky moment = is based on the idea that periods of speculation if they last long enough will
eventually lead to crises; the longer speculation occurs  the worse the crisis will be.

In order to have a Minsky moment = there needs to be excessive speculation = fueled by over
borrowing + over-spending  prices are (bid up like this) so high because people are able to borrow
money.

Graph of credit market debt (as percentage of GDP) has expanded over the course  huge growth in
credit both in Great Depression + in financial crisis in 2008  in both cases = investors + speculators
= realize that prices cannot keep rising indefinitely  so they begin to sell

Everyone was so over leveraged when they began to sell  prices began to decline (asset prices
deflation) = people started to go bankrupt

Everyone was using credit + speculating  pushing prices up BUT the amount of debt was getting
bigger and bigger until people realized that this amount of debt + levels of prices = was not
