Danger! Danger! Devaluation!

Right now, Brexiters keep claiming that devaluation is good for the economy. They're almost certainly wrong.

Intuitively, a fall in the pound is a bad thing: anything we buy from overseas goes up in price and since a high proportion of what we buy comes from overseas, our cost of living will go up.

But then Brexiters jump in and say "Devaluation is great, because it means more exports and that will make the economy grow." As a general rule, because Brexiters often distort the truth, you should be skeptical. So, are they wrong here too?

It's a good question. Recently I was at my Dad's house and we were watching a TV show called "Factory Wars" on the Yesterday channel. I was surprised to find a bloke from The Institute of Economic Affairs. Why was an economist from a lobbying organisation with secretive funding (hint, Big tobacco and the climate denying US groups like the Heartland Institute) on a history show?

Basically he was using it to push free market ideology. He claimed that the UK escaped the recession in the 1930s because it implemented austerity unlike the US which implemented a Keynesian New Deal. This was completely different to how I'd understood these economies in the 1930s: on the basis that austerity empirically doesn't work; its easy to explain why, and it was the Keynesian New Deal that empowered the US to manufacture the armaments that helped the allies overcome the Nazis.

It's not coincidence that the IEA offered a completely different explanation than what is normally understood: they're based at 55, Tufton Street where Vote Leave was also based. So, again we have another ideologue whose views we should suspect.

So, I checked out what really happened in the UK's economy in the 1930s? Economics Help is really useful. Basically, the crash of 1929 caused a lot of hardship in the UK, but in the mid to late 1930s we dropped the gold standard; which lead to a deflation of the pound and this lead to a mild economic recovery in the south, but the North still had it tough.

So, it looks like Brexiters might be a bit right, and the IEA were misleading as normal. But is it?

Devaluation Model

Actually we can work this out ourselves, because it's easy to model. In our model (for a business, but it can apply at a larger scale) we consider just three variables:

  1. Profits
  2. Internal costs (labour minus rises in the cost of living due to buying overseas goods, maintenance of equipment etc). We assume this is a constant.
  3. Imports (including the increases in the cost of living for employees from overseas goods).

Case A

In the first scenario, we consider a company with reasonably high import costs (50%), a profit margin of 30% and the rest is internal costs (20%). If the pound deflates by 25%, then imports go up to 50*1.25 = 62.5%. So, now our profits are 30-12.5 = 17.5% profits. This means that the company needs to sell 30/17.5 = 71% more goods, but the domestic market will buy less, and the overseas market will only find its products are 25% cheaper (due to devaluation).

So, the question is: is it like overseas customers will buy 71% more, if it's 25% cheaper? This seems unlikely to me.

Case B

Let's consider the second case: profits are 70%, internal costs 20% and imports are 10%. Imports increase by 25% => 12.5%, so we now need to sell: 70/(70-2.5) = 3.7% more. OK, so in this case our product is 25% cheaper, and we only need to sell 3.7% more for us to make more profit, this seems plausible.

So, we have to ask ourselves, what kinds of businesses are like this? Mass market manufacturing (cars, aircraft, smoke alarms) will rely a lot on imports and will make a relatively small profit. Apple, for example has margins between 20% to 30%. Dyson is also about 21%. DELL has an operating profit of just 1.1%. Companies producing consumer items such as smoke alarms have fairly low margins which explains why they would move to cheaper EU countries.

What companies are like case B? Services and financial companies are like that. However, financial companies are likely to move out of the UK due to Brexit, so this means service companies would benefit.

However, to some people, UK manufacturing companies can look good: namely, if you hold a lot of offshore wealth, then UK manufacturing companies struggling under devaluation look like a good buy. In other words, disaster capitalists with offshore accounts, such as people like Jacob Rees Mogg and a large proportion of Conservative party members and MPs.

Epilogue

Brexiters are wrong: it's just a front for their disaster capitalist mission. We can summarise our model and convey why in a simple table:



So, why did the UK not crash due to a double-whammy of austerity and devaluation in the 1930s? That's pretty simple, being the biggest power bloc at the time meant that although most of its food (91%?) was imported along with a significant proportion of goods, a great deal of this was essentially an internal market, with the added advantage that many resources, particularly coal were internal.

dark web links

These days, we are all too familiar with the advantages of dark web links. They are not a new thing at all, as they have been around for quite some time now. In fact, any person who is familiar with online marketing will already be aware of them, because links on the dark side of the net are nothing new. But what many people do not realize is that they can be very useful tools when it comes to getting traffic to your website. Although this particular type of link building service has been around since the early nineties, people do not do very much with them any more due to the rise of search engines. But before you dismiss them altogether, let us examine how useful they can be in this day and age.
