The removal of transaction costs associated with exchanging currency has another effect. Intra-European investment flows would likely increase. This means that companies across the Euro zone would benefit from increased investment from other Euro zone countries.
Ultimately a Single European Currency goes one big step further to the completion of the Single European Market, by opening up the markets of each member and linking them with one currency. Labour markets are also linked and the economies of the Euro zone can become more synchronized, lending themselves to full-on integration. The completion of a Single European Market has one major advantage - there will finally be a major competitor to the U.S.A. in the global economy. Economists predict that the U.S.A. and Euro zone Europe will become the two major players with Japan as a junior partner in the world economy. This has particular relevance now, since many economies at the moment, particularly our own, hinge on the US economy. If it slows down, like it is about to, then those other countries are likely to do the same. With another competitor to the US, the global economy can become much more balanced and with it bring possibly more stability.
Obviously a key factor in Britain's decision to join the Euro would be whether or not it would help reduce unemployment. Unemployment is currently falling within the Euro zone. Unemployment within the Euro zone is currently higher than that within Britain. However, if the downward trend continues then it should be at UK levels within a couple of years.
In theory, once at these levels, unemployment should stay low since there will be a far wider labour market where workers can seek employment. Also, demand should increase due to the competition created by lower transaction costs, so output will be higher:
Arguments Against the Euro
The arguments against the UK's membership in the Euro zone are also split into political and economic arguments.
Political arguments include the loss of Britain's individuality as a separate country, as well as the loss of nearly all control over the UK economy. Furthermore, adopting the Euro more or less ties Britain into any future plans of a Federal Europe. It would be hard to back out of such plans with so much integration already set in motion. This, of course, would mean the loss of political sovereignty for Britain.
It is the economic arguments against the Euro that are the most important and in many ways the most compelling.
Economic theory states that the macro objectives for a government are as follows:
• Low unemployment
• Low inflation
• Economic growth
• Balance of Pay Equilibrium
In order to succeed in these objectives, governments use policies to control various aspects of the economy:
• Monetary Policy
• Fiscal Policy
• Supply-side Policies
• Exchange Rate Policies
In the analysis that follows, it will be shown that three of these policies would be rendered unusable to control the UK economy:
1. Monetary Policy
Monetary policy involves the raising and lowering of the base rate to control aggregate demand. For example, if aggregate demand is rising too quickly and raising prices (demand-pull inflation):
In this situation, the government could increase the base rate. This would have the effect of lowering consumer expenditure since there would be a higher incentive to save and a higher cost of borrowing.
The introduction of the Euro in the UK would make this policy unusable because interest rates for Euro zone members are set by the European Central Bank (ECB) and is the same for all member countries. Of course, the ECB is able to operate Monetary Policy over the whole Euro zone, but an increase or decrease in aggregate demand might have a positive effect on one economy but a negative one on another. Economists argue whether the economies of the Euro zone are suitably synchronized to allow policies such as this to be used universally.
2. Fiscal Policy
Fiscal policy is closely linked to monetary policy and is also used to control aggregate demand. However, it does so by controlling the amount of government spending and taxation. Increasing government spending will increase aggregate demand.
Increasing taxation means that incomes are lowered, which causes consumer expenditure to go down which means that aggregate demand, goes down (see above). Of course, both can be applied vice versa as well.
Fiscal policy becomes more or less useless with the adoption of the Euro, since one of the convergence criteria for joining the Euro zone is a low government debt. This means that the government cannot increase government spending to increase aggregate demand.
3. Exchange Rate Policy
Exchange Rate Policy is the devaluation and revaluation of a currency in order to deal with a balance of payments deficit. Little needs to be said here, since obviously with membership of the single currency this will be out of the control of the British government and in the hands of the ECB.
This leaves only Supply-Side Policies, which are rather limited in their applications. They involve deregulation to lower costs of production for businesses, and increasing labour productivity to increase growth rate (by promoting competition, privatisation, reducing strikes, etc.)
The main reason behind setting the Euro in the first place is to promote economic growth within Euro zone countries.
Gordon Brown's Five Economic Tests
Gordon Brown, the current Chancellor of the Exchequer, has put forward five economic tests that he thinks the UK should meet before it can join the Euro. They are:
1. Whether the UK has achieved sustainable economic convergence
2. Whether there is sufficient flexibility in the economy
3. Whether joining would create better conditions for long-term decision making
4. The impact of the Euro on financial services
5. Whether joining would be good for employment
If the UK economy passes all 5 of these tests then it is likely that the government will hold a referendum to decide whether or not to join.
Conclusion
Having analysed both the pros and cons of membership in the Euro zone, I conclude that at this time it probably is not beneficial to join. This is for two main reasons.
Firstly, the UK economy is at its strongest at the moment and has still has prospects despite opting-out of the Euro for the moment. Capital inflow is likely to continue even if we stay out of the single currency and the UK still has attractive supply-side factors in both product and labour markets for foreign investors. Particularly, the UK will remain attractive for Far Eastern countries such as Japan and other Asian economies.
Secondly, I think that currently the risks outweigh the advantages that would be gained. As mentioned before, the UK economy is at its peak and is doing considerably better than other Euro zone members. If the UK joined the Euro then it is highly possible that the less fortunate countries will drag the UK down with them. Furthermore, the ECB will likely have to take relatively drastic action to keep some of the poorer economies in the Euro zone in check. This could have adverse effects on the otherwise sound economy of Britain. The problem is that the economies of the Euro zone are not suitably synchronised to allow economic control to be universal over all of them. Universal measures are the only option with a single currency. If Britain opts-out for the time being until the single currency has had a chance to both synchronise and improve the economies of the Euro zone, then it might be in a better position to offer advantages that outweigh the risks. On the other hand, if the Euro fails miserably and its economies go into recession, then we will be suitably distant from it to avoid unnecessary damage to our own economy.
