In two posts recently, we considered the pessimistic views of Robert Peston about the prospects for the global economy (see Cloudy skies ahead? and The end of growth in the West?). In this post we consider the views of Christine Lagarde, Managing Director of the International Monetary Fund, and Lord Adair Turner, the former head of the Financial Services Authority (FSA) (which was replaced in 2013 by the Financial Conduct Authority and the Prudential Regulation Authority).
Christine Lagarde was addressing an audience at Georgetown University in Washington DC. The first four links below are to webcasts of the full speech and subsequent interviews about the speech. 
She gives a more gloomy assessment of the global economy than six months ago, especially the eurozone economy and several emerging economies, such as China. There are short- to medium-term dangers for the world economy from political conflicts, such as that between Russia and the West over Ukraine. But there are long-term dangers too. These come from the effects of subdued private investment and low infrastructure spending by governments.
Her views are backed up by the six-monthly World Economic Outlook, published by the IMF on 7 October. There are links below to two webcasts from the IMF discussing the report and the accompanying datasets.
In the final webcast link below, Lord Turner argues that there is a “real danger of a simultaneous slowdown producing a big setback to growth expectations.” He is particularly worried about China, which is experiencing an asset price bubble and slowing economic growth. Other emerging economies too are suffering from slowing growth. This poses real problems for developed countries, such as Germany, which are heavily reliant on their export sector.

At least once a year The Economist publishes its ‘hamburger standard’ exchange rates for currencies. It is a light-hearted attempt to see if currencies are exchanging at their purchasing-power parity rates. The test is the price at which a ‘Big Mac’ McDonald’s hamburger sells in different countries!
According to this simplified version of the purchasing-power parity theory, exchange rates should adjust so that a Big Mac costs the same in dollars everywhere (see Economics 8th edition Box 25.4).
These Big Mac exchange rates can be used to compare various prices and incomes between countries. The article linked below from The Guardian compares minimum wages between European countries in Big Mac terms.
There are 25 countries across Europe which have minimum wages. A clear pattern of minimum wage rates can be seen: although actual exchange rates understate the purchasing power of incomes in poorer European countries compared to richer ones, minimum wages, even in purchasing-power standard terms, are still higher in the richer countries.
Luxembourg’s minimum wage buys you just about three Big Macs in an hour, while most of northern Europe (and France) between 2–2.5 Big Macs. Moving south, the minimum wage nets about one Big Mac an hour. As we progress east, it begins to cost more than an hour of work on the minimum wage in order to afford a Big Mac.
Of course, there are other factors determining the dollar price of a Big Mac other than the failure of exchange rates to reflect purchasing-power parities. Nevertheless, using the Big Mac index in this way does give a useful preliminary snap shot of differences in what minimum wages can buy in different countries.

The French economy is flatlining. It has just recorded the second quarter of zero economic growth, with growth averaging just 0.02% over the past 12 months. What is more, the budget deficit is rising, not falling. In April this year, the French finance minister said that the deficit would fall from 4.3% in 2013 to 3.8% in 2014 and to the eurozone ceiling of 3% in 2015. He is now predicting that it will rise this year to 4.4% and not reach the 3% target until 2017.
The deficit is rising because a flatlining economy is not generating sufficient tax revenues. What is more, expenditure on unemployment benefits and other social protection is rising as unemployment has risen, now standing at a record 10.3%.
And it is not just the current economic situation that is poor; the outlook is poor too. The confidence of French companies is low and falling, and investment plans are muted. President Hollande has pledged to cut payroll taxes to help firms, but so far this has not encouraged firms to invest more.
So what can the French government do? And what can the EU as a whole do to help revive not just the French economy but most of the rest of the eurozone, which is also suffering from zero, or near zero, growth?
There are two quite different sets of remedies being proposed.
The first comes from the German government and increasingly from the French government too. This is to stick to the austerity plans: to get the deficit down; to reduce the size of government in order to prevent crowding out; and to institute market-orientated supply-side policies that are business friendly, such as reducing business regulation. Business leaders in France, who generally back this approach, have called for reducing the number of public holidays and scrapping the maximum 35-hour working week. They are also seeking reduced business taxes, financed by reducing various benefits.
Increasingly President Hollande is moving towards a more business-friendly set of policies. Under his government’s ‘Responsibility Pact’, a €40 billion package of tax breaks for business will be financed through €50 billion of cuts in public spending. To carry through these policies he has appointed an ex-investment banker, Emmanuel Macron, as economy minister. He replaces Arnaud Montebourg, who roundly criticised government austerity policy and called for policies to boost aggregate demand.
This brings us to the alternative set of remedies. These focus on stimulating aggregate demand through greater infrastructure investment and cutting taxes more generally (not just for business). The central argument is that growth must come first and that this will then generate the tax revenues and reductions in unemployment that will then allow the deficit to be brought down. Only when economic growth is firmly established should measures be taken to cut government expenditure in an attempt to reduce the structural deficit.
There are also compromise policies being proposed from the centre. These include measures to stimulate aggregate demand, mainly through tax cuts, accompanied by supply-side policies, whether market orientated or interventionist.
As Europe continues to struggle to achieve recovery, so the debate is getting harsher. Monetary policy alone may not be sufficient to bring recovery. Although the ECB has taken a number of measures to stimulate demand, so far they have been to little avail. As long as business confidence remains low, making increased liquidity available to banks at interest rates close to zero will not make banks more willing to lend to business, or businesses more willing to borrow. Calls for an end, or at least a temporary halt, to austerity are thus getting louder. At the same time, calls for sticking to austerity and tackling excessive government spending are also getting louder.

Commodity prices have been falling for the past three years and have reached a four-year low. Since early 2011, the IMF overall commodity price index (based on 2005 prices) has fallen by 16.5%: from 210.1 in April 2011 to 175.4 in August 2014. The last time it was this low was December 2010.
Some commodity prices have fallen by greater percentages, and in other cases the fall has been only slight. But in the past few months the falls have been more pronounced across most commodities. The chart below illustrates these falls in the case of three commodity groups: (a) food and beverages, (b) agricultural raw materials and (c) metals, ores and minerals. (Click here for a PowerPoint of the chart.)
Commodity prices are determined by demand and supply, and factors on both the demand and supply sides have contributed to the falls.
With growth slowing in China and with zero growth in the eurozone, demand for commodities has shown little growth and in some cases has fallen as stockpiles have been reduced.
On the supply side, investment in mining has boosted the supply of minerals and good harvests in various parts of the world have boosted the supply of many agricultural commodities.
But in historical terms, prices are still relatively high. There was a huge surge in commodity prices in the period up to the financial crisis of 2008 and then another surge as the world economy began to recover from 2009–11. Nevertheless, taking a longer-term perspective still, commodity prices have risen in real terms since the 1960s, but with considerable fluctuations around this trend, reflecting demand and supply at the time.

Economic journalists, commentators and politicians have been examining the possible economic effects of a Yes vote in the Scottish independence referendum on 18 September. For an economist, there are two main categories of difficulty in examining the consequences. The first is the positive question of what precisely will be the consequences. The second is 
the normative question of whether the likely effects will be desirable or undesirable and how much so.
The first question is largely one of ‘known unknowns’. This rather strange term was used in 2002 by Donald Rumsfeld, US Secretary of Defense, in the context of intelligence about Iraq. The problem is a general one about forecasting the future. We may know the types of thing that are likely happen, but the magnitude of the outcome cannot be precisely known because there are so many unknowable things that can influence it.
Here are some known issues of Scottish independence, but with unknown consequences (at least in precisely quantifiable terms). The list is certainly not exhaustive and you could probably add more questions yourself to the list.
|
|
| • |
Will independence result in lower or higher economic growth in the short and long term? |
| • |
Will there be a currency union, with Scotland and the rest of the UK sharing the pound and a central bank? Or will Scotland merely use the pound outside a currency union? Would it prefer to have its own currency or join the euro over the longer term? |
| • |
What will happen to the sterling exchange rate with the dollar, the euro and various other countries? |
| • |
How will businesses react? Will independence encourage greater inward investment in Scotland or will there be a net capital outflow? And either way, what will be the magnitude of the effect? |
| • |
How will assets, such as oil, be shared between Scotland and the rest of the UK? And how will national debt be apportioned? |
| • |
How big will the transition costs be of moving to an independent Scotland? |
| • |
How will independence impact on Scottish trade (a) with countries outside the UK and (b) with the rest of the UK? |
| • |
What will happen about Scotland’s membership of the EU? Will other EU countries, such as Spain (because of its concerns about independence movements in Catalonia and the Basque country), attempt to block Scotland remaining in or rejoining the EU? |
| • |
What will happen to tax rates in Scotland, with the new Scottish government free to set its own tax rates? |
| • |
What will be the consequences for Scottish pensions and the Scottish pensions industry? |
| • |
What will happen to the distribution of income in Scotland? How might Scottish governments behave in terms of income redistribution and what will be its consequences on output and growth? |
Of course, just because the effects cannot be known with certainty, attempts are constantly being made to quantify the outcomes in the light of the best information available at the time. These are refined as circumstances change and newer data become available.
But forecasts also depend on the assumptions made about the post-referendum decisions of politicians in Scotland, the rest of the UK and in major trading partner countries. It also depends on assumptions about the reactions of businesses. Not surprisingly, both sides of the debate make assumptions favourable to their own case.
Then there is the second category of question. Even if you could quantify the effects, just how desirable would they be? The issue here is one of the weightings given to the various costs and benefits. How would you weight distributional consequences, given that some people will gain or lose more than others? What social discount rate would you apply to future costs and benefits?
Then there are the normative and largely unquantifiable costs and benefits. How would you assess the desirability of political consequences, such as greater independence in decision-making or the break-up of a union dating back over 300 years? But these questions about nationhood are crucial issues for many of the voters.

Questions
- What is a currency union? What implications would there be for Scotland being in a currency union with the rest of the UK?
- If you could measure the effects of independence over the next ten years, would you treat £1m of benefits or costs occurring in ten years’ time the same as £1m of benefits and costs occurring next year? Explain.
- Is it inevitable that events occurring in the future will at best be known unknowns?
- If you make a statement that something will occur in the future and you turn out to be wrong, was your statement a positive one or a normative one?
- What would be the likely effects of Scottish independence on the current account of the balance of payments (a) for Scotland; (b) for the rest if the UK?
- How does inequality in Scotland compare with that in the rest of the UK and in other countries? Why might Scottish independence lead to a reduction in inequality? (See the chapter on inequality in the book above edited by David Bell, David Eiser and Klaus B Beckmann.)
- One of the problems in assessing the arguments for a Yes vote is uncertainty over what would happen if there was a majority voting No. What might happen in terms of further devolution in the case of a No vote?
- Why is there uncertainty over the amount of national debt that would exist in Scotland if it became independent?
