Since WWII, the British economy can be characterised as being prone to inflation and having a structural trade account deficit. It looks like the UK is reverting to type. Inflation is high compared with other developed nations and the trade account is stubbornly negative. Why does the UK suffer from these twin problems? I’ve seen no research or comment on this, so I’ll attempt an explanation as I think the two are linked.
It seems logical to argue that countries that have structural trade account deficits should suffer from structurally weak currencies. The counterpart to a trade deficit is that trading partners accumulate currency and liabilities from the deficit countries. The liabilities in the deficit currency increase relative to the quantity of goods that the country produces and the assets that it has available for sale. Hence, other things being equal, this should produce inflation (the value of money declines relative to goods and assets) and weaken the currency, intensifying inflationary pressures.
If I had access to all the data providers that I had when I was working, I’m sure that I would be able to prove this statistically. However, if we think anecdotally, the UK fits into this pattern. The trade account has been generally negative and the currency weak since WWII.
The US is also an interesting case. It is suffering from lower than average inflation despite a chronic trade account deficit. However, inflation is systematically under-reported in the US because of its use of hedonic adjustments and judicious changes in the mix of components. Over the past 20-30 years inflation in the US has been higher than in Japan or Germany, two nations with structural trade surpluses.
The eurozone is also an interesting example. Within the eurozone, the deficit countries suggest that even without currency devaluation, this interaction of external liabilities and internal goods and assets produces inflationary pressures.
If we think of Spain, a trade deficit with Germany means that Germany is accumulating claims on Spain. Spain does not produce enough tradable goods to redeem those claims, so the scarcity of Spanish tradable goods may lead to some inflation in those goods. However, because of competition in the tradable goods sector this is likely to be a minor effect. More likely is that some of those claims will be redeemed against real estate in Spain. Indeed, this seems to be the more likely avenue of inflationary pressure.
It is this imbalance between the supply of liabilities and the production of goods (and assets) that is at the heart of the linkage between structural trade deficits and higher inflation. This is another reason to believe that the eurozone has some fatal structural flaws that doom it to failure.
We can also think of this in terms of final demand in an economy. By definition, economies that have structural trade deficits have domestic demand in excess of domestic supply. Other things being equal, this ought to produce upward pressures on inflation. This may be disguised if the price of tradable goods is weak. This has been the case over the past 15 years as China has ramped up production and increases in productivity has outweighed increases in input prices. Recent events seem to suggest that this process is coming to and end.
What about China? It has a massive trade surplus, but is suffering from rising inflation. It could be argued that China would be suffering even greater inflation if it weren’t for the trade surplus. Indeed, if it weren’t manipulating its currency, then inflation would be much lower. As emerging economies tend to have higher inflation, it is plausible to argue that the trade surplus has pushed down inflation by suppressing domestic demand.
Returning to the UK, the structural trade deficit has been indicative of excess domestic demand (recently fuelled by an increase in borrowing) producing inflationary pressures. This has been compounded by sterling weakness. Indeed, it is interesting to note that the decline in the exchange rate has been cited as one of the main drivers of higher than expected inflation by the Bank of England. If domestic production is unable to take advantage of rising import costs through substitution, then inflation must emerge.
Looking back over history, it is easy to see that the decline in the sterling exchange rate in the 1970s caused inflationary pressures. The strength of sterling in part of the 1980s as a consequence of North Sea oil helped to push inflationary pressures down. The stability of sterling in the late 1990s and early 2000s ameliorated inflationary pressures. However, now that North Sea oil production is declining, downward pressure on sterling has resumed and with it, inflationary pressures have surprisingly strong.
Unless this structural problem in the UK is addressed, the UK is doomed to a weak exchange rate and higher than average inflation. Recent trade statistics suggest that without a change in economic policy, the UK will not achieve the desired rebalancing of its economy.
The first issue the UK faces is that its economy is relatively open and large enough that it is one of the first economies that other countries want to export to. It has very efficient retail distribution. For instance, if an exporter wants to access UK supermarkets, it only needs to deal with four companies to gain access to the vast majority of consumers. In clothing, a handful of companies account for the vast majority of sales. The UK economy is also large and diverse enough that it can be attractive for high value, niche products as well.
One policy option might be to try to raise trade barriers in some way. However, this would be extremely difficult with the UK’s membership of the EU and WTO. It would also be inflationary as low unit cost imports would be replaced by high unit cost domestic production. So this appears to be a non-starter as a policy option.
A better policy would be to in some way incentivise export production. Another common feature of countries with a structural trade deficit appears to be underinvestment, particularly in areas that would produce export earnings. The UK has been plagued by under-investment since the 1950s.
It would not be enough to just encourage investment. Some deficit countries have higher investment rates but investment has been directed towards real estate, which has little or no use as an export good. Investment incentives would have to be directed towards productive capacity and not leak to the real estate sector.
In essence, the UK has to rediscover a mercantilist policy mix without excessively distorting the whole economy. Incentives to invest in productive capacity and for overseas companies to relocate productive capacity to the UK should be a major plank of policy.
However, the real trick would be to grow productive capacity in high valued added areas. A broad brushed investment incentive would favour high capital intensity, low value added investment. This would leave the UK vulnerable to swings in the exchange rate. Obviously, if the trade deficit disappeared due to investment incentives, then sterling would suffer less structural weakness and might even rise. A rising exchange rate would be problematic for high capital intensity, low value added industries and any policy that favoured these would be self defeating.
So what to do? My suggestion would be to improve the attractiveness of the UK as a place to do business. Unfortunately, recent public policy has tended to be the opposite. The government needs to sit down with industry leaders and work out how it can make Britain more attractive as a place to do business.
The second area it needs to address is education and skill shortages. In education, there needs to be more focus on the skills that are vital to a knowledge and high value added economy. I would focus on the basics such as maths, science and literacy, but I would also encourage design and creative subjects. Additionally, I would have some training in economic, how to run a business and personal finance.
The third thing I would do is to encourage areas where the UK appears to have a competitive advantage. For instance, pharmaceuticals, aerospace, instrumentation and electronics appear to be areas where the UK has successful companies. Ask companies in these areas what they need to be even more successful. Some modest tax incentives might be appropriate, but many would probably say better support from governmental bodies and export finance.
Fourthly, I would make it easier to access finance for start up and for small and medium sized businesses. However, any government support would need to be focussed on industries which might help our trade balance. Too many enterprise schemes have been used as tax dodges in real estate and the consumer sector. Ensuring backing for the right type of company would not be easy. Carte blanche cheque writing is not the answer. The Department of Trade and Industry would need to have some re-staffing with some venture capital types.
Let’s hope our leaders won’t let a good crisis go to waste. Unfortunately, I think policy is getting sidetracked by ridiculous ideas like extended paternity leave, which only makes the UK less competitive.
