Economies of scope occur when a firm can gain efficiencies from producing a wider variety of products. These efficiencies can involve lower average costs. It can also involve increased revenue from being able to increase sales in new, related markets. It is similar to concept of economies of scale – where higher output leads to …

Liquidity explained

liquidity-trap-ms-demand-for-money

Liquidity refers to the ease at which assets can be converted into cash.

  • An asset is said to be liquid if it is easy to buy and sell; for example, short-date government gilts are a highly liquid market because it is easy to sell on the bond markets.
  • As asset is said to be illiquid if it is difficult to buy and sell. For example, a house is a very illiquid asset because to sell a house requires considerable time and expense. By the time you have found a buyer, the price of a house may have changed considerably – especially during boom and busts.

The importance of liquidity

An investor may need both liquid and illiquid assets. You need liquid assets to deal with any unexpected short-term crisis. But, illiquid assets may offer a greater chance for capital gains and higher yield.

For example, if you put money in a current account, you have instantaneous access, but interest rates tend to be low. If you put money in a time deposit account, you have to give the bank a seven day or 30-day advance warning you need the money. This makes your savings more illiquid, but the bank compensates by paying a higher interest rate.

Liquidity ratio

A liquidity ratio refers to the number of liquid assets to overall assets. If a firm is highly liquid – it has a high proportion of assets that can easily be converted to cash to pay off any obligations.

A low liquidity ratio means a firm has a shortage of liquid assets and may struggle to meet short-term debt obligations.

Cash reserve ratio

A bank may be required to keep a certain percentage of its assets in the form of liquid assets. It is the fraction of customer deposits held in cash reserves.

Cash reserves are not profitable. If a bank lends deposits to other customers, it can charge interest and make more profit. But bank loans are highly illiquid because the bank cannot immediately ask for the loan back.

Bank Liquidity measured by Bank of England
Bank Liquidity fell to a record low in 2005.

A problem of the credit crisis is that banks had a very low cash-reserve ratio. This led to a liquidity crisis when banks couldn’t raise sufficient funds on short-term money markets.

What happened to the Spanish Gold from the Incas?

gold

I’m currently reading A History of the World by Andrew Marr (it’s a good read so far). There’s an interesting chapter about the consequence of Spain gaining a large quantity of gold and silver from the Incas during the Sixteenth Century. Almost overnight, Spain became very rich taking home unprecedented quantities of gold and silver. These were stolen from the Incas and the mines that the Spanish came to control.

The gold was used by the Spanish monarchy to pay off its debts and also to fund its ‘religious’ wars. Therefore, gold started to trickle out to other European countries who benefited from the Spanish wealth.

The Spanish also were able to purchase an unprecedented quantity of imported goods from around the world – including Europe and China.

Impact of inflow of Gold on Spanish economy

For me, the most interesting thing is the theory that the sudden influx of gold actually contributed to Spain’s relative decline and low living standards in future centuries. How could an influx of gold cause this?

One theory suggests that – because the Spanish had so much gold, they could easily buy commodities from other countries without producing them itself. Because consumer goods could easily be bought, there was little incentive to produce goods and undertake the necessary investment and develop the technology to produce goods. Therefore, it is argued this ‘easy wealth’ was a factor in limiting economic development.

In macro terms, we could see Sixteenth-Century Spain has a country with a very large trade deficit – financed by capital inflows (stolen gold). But, this is an unbalanced economy – consumption enables high current living standards, but when the gold dried up, Spanish business and industry had been left behind other European nations. Nations without a windfall of gold had a much greater drive to create wealth rather than just consume it.

Therefore, the sudden inflow of gold was not good for the long-term development of the Spanish economy. But, partly explains why the Spanish economy came to lag behind the rest of Europe until the post-war period.

Great Britain, by contrast, arguably, gained just about the right amount of gold. National hero Francis Drake was really just a pirate. He attacked Spanish ships and took some of the gold. (It is estimated about 10% of Spanish gold was lost to piracy). Francis Drake gave a good portion of his stolen gold to Queen Elizabeth I – who used this windfall to pay off the UK national debt. (so, I suppose piracy is one way to deal with a national debt).

However, Great Britain never gained enough of the Latin American gold to become just a nation of consumers. The prospect of gold actually motivated a rapid expansion in naval technology. It was around this time, that Britain’s navy and shipbuilding capacity increased rapidly. This sowed the seeds of Britain’s future Empire. But, it was an Empire which was at least partly based on industry and production. We may have exploited natural resources in countries like India, but we also had the incentive to manufacture goods – and this motivation contributed to the industrial revolution.

It is an irony of history that had Great Britain received a huge windfall of gold, the industrial revolution may not have started in Great Britain – because the incentive for business to take risks and develop industry would not have been as strong. Therefore, be careful what you wish for!
