Question #497

Fiscal rules such as are embodied in the Stability and Growth Pact of the EMU will continually create conditions of slower growth because they deprive the government of fiscal flexibility to support aggregate demand when necessary.

Answer #2904

Answer: False

Explanation

The answer is False.

The fiscal policy rules that were agreed in the Maastricht Treaty - budget deficits should not exceed 3 per cent of GDP and public debt should not exceed 60 per cent of GDP - clearly constrain EMU governments during periods when private spending (or net exports) are draining aggregate demand.

In those circumstances, if the private spending withdrawal is sufficiently severe, the automatic stabilisers alone will drive the budget deficit above the required limits. Pressure then is immediately placed on the national governments to introduce discretionary fiscal contractions to get the fiscal balance back within the limits.

Further, after an extended recession, the public debt ratios will almost always go beyond the allowable limits which places further pressure on the government to introduce an extended period of austerity to bring the ratio back within the limits. So the bias is towards slower growth overall.

It is also true that the fiscal rules clearly (and by design) "deprive the government of fiscal flexibility to support aggregate demand when necessary". But that wasn't the question. The question was will these rules continually create conditions of slower growth. The answer is no they will not.

Imagine a situation where the nation has very strong net exports adding to aggregate demand which supports steady growth and full employment without any need for the government to approach the Maastricht thresholds. In this case, the fiscal rules are never binding unless something happens to exports.

The following is an example of this sort of nation. It will take a while for you to work through but it provides a good learning environment for understanding the basic expenditure-income model upon with Modern Monetary Theory (MMT) builds its monetary insights. You might want to read this blog - Back to basics - aggregate demand drives output - to refresh your understanding of the sectoral balances.

The following Table shows the structure of the simple macroeconomic model that is the foundation of the expenditure-income model. This sort of model is still taught in introductory macroeconomics courses before the students get diverted into the more nonsensical mainstream ideas. All the assumptions with respect to behavioural parameters are very standard. You can download the simple spreadsheet if you want to play around with the model yourselves.

The first Table shows the model structure and any behavioural assumptions used. By way of explanation:

You might want to right-click the images to bring them up into a separate window and the print them (on recycled paper) to make it easier to follow the evolution of this economy over the 10 periods shown.

The next table quantifies the ten-period cycle and the graph below it presents the same information graphically for those who prefer pictures to numbers. The description of events is in between the table and the graph for those who do not want to print.

The graph below shows the sectoral balances - budget deficit (red line), external balance (blue line) and private domestic balance (green line) over the 10-period cycle as a percentage of GDP (Y) in addition to the period-by-period GDP growth (y) in percentage terms (grey bars).

Above the zero line means positive GDP growth, a budget deficit (G > T), an external surplus (X > M) and a private domestic deficit (I > S) and vice-versa for below the zero line.

This is an economy that is enjoying steady GDP growth (1.4 per cent) courtesy of a strong and growing export sector (surpluses in each of the first three periods). It is able to maintain strong growth via the export sector which permits a budget surplus (in each of the first three periods) and the private domestic sector is spending less than they are earning.

The budget parameters (and by implication the public debt ratio) is well within the Maastricht rules and not preventing strong (full employment growth) from occurring. You might say this is a downward bias but from in terms of an understanding of functional finance it just means that the government sector is achieving its goals (full employment) and presumably enough services and public infrastructure while being swamped with tax revenue as a result of the strong export sector.

Then in Period 4, there is a global recession and export markets deteriorate up and governments delay any fiscal stimulus. GDP growth plunges and the private domestic balance moves towards deficit. Total tax revenue falls and the budget deficit moves into balance all due to the automatic stabilisers. There has been no discretionary change in fiscal policy.

In Period 5, we see investment expectations turn sour as a reaction to the declining consumption from Period 4 and the lost export markets. Exports continue to decline and the external balance moves towards deficit (with some offset from the declining imports as a result of lost national income). Together GDP growth falls further and we have a technical recession (two consecutive periods of negative GDP growth).

With unemployment now rising (by implication) the government reacts by increasing government spending and the budget moves into deficit but still within the Maastricht rules. Taxation revenue continues to fall. So the increase in the deficit is partly due to the automatic stabilisers and partly because discretionary fiscal policy is now expanding.

Period 6, exports and investment spending decline further and the government now senses a crisis is on their hands and they accelerate government spending. This starts to reduce the negative GDP growth but pushes the deficit beyond the Maastricht limits of 3 per cent of GDP. Note the rising deficits allows for an improvement in the private domestic balance, although that is also due to the falling investment.

In Period 7, even though exports continue to decline (and the external balance moves into deficit), investors feel more confident given the economy is being supported by growth in the deficit which has arrested the recession. We see a return to positive GDP growth in this period and by implication rising employment, falling unemployment and better times. But the deficit is now well beyond the Maastricht rules and rising even further.

In Period 8, exports decline further but the domestic recovery is well under way supported by the stimulus package and improving investment. We now have an external deficit, rising budget deficit (4.4 per cent of GDP) and rising investment and consumption.

At this point the EMU bosses take over and tell the country that it has to implement an austerity package to get their fiscal parameters back inside the Maastricht rules. So in Period 9, even though investment continues to grow (on past expectations of continued growth in GDP) and the export rout is now stabilised, we see negative GDP growth as government spending is savaged to fit the austerity package agree with the EMU bosses. Net exports moves towards surplus because of the plunge in imports.

Finally, in period 10 the EMU bosses are happy in their warm cosy offices in Brussels or Frankfurt or wherever they have their secure, well-paid jobs because the budget deficit is now back inside the Maastricht rules (2.9 per cent of GDP). Pity about the economy - it is back in a technical recession (a double-dip).

Investment spending has now declined again courtesy of last period's stimulus withdrawal, consumption is falling, government support of saving is in decline, and we would see employment growth falling and unemployment rising.

Question 5 - Premium question

In Year 1, the economy plunges into recession with nominal GDP growth falling to minus -1 per cent. The inflation rate is subdued at 1 per cent per annum. The outstanding public debt is equal to the value of the nominal GDP and the nominal interest rate is equal to 1 per cent (and this is the rate the government pays on all outstanding debt). The government's budget balance net of interest payments goes into deficit equivalent to 1 per cent of GDP and the debt ratio rises by 3 per cent. In Year 2, the government stimulates the economy and pushes the primary budget deficit out to 2 per cent of GDP and in doing so stimulates aggregate demand and the economy records a 4 per cent nominal GDP growth rate. All other parameters are unchanged in Year 2. Under these circumstances, the public debt ratio will rise but by an amount less than the rise in the budget deficit because of the real growth in the economy.

The answer is False.

This question requires you to understand the key parameters and relationships that determine the dynamics of the public debt ratio. An understanding of these relationships allows you to debunk statements that are made by those who think fiscal austerity will allow a government to reduce its public debt ratio.

While Modern Monetary Theory (MMT) places no particular importance in the public debt to GDP ratio for a sovereign government, given that insolvency is not an issue, the mainstream debate is dominated by the concept.

The unnecessary practice of fiat currency-issuing governments of issuing public debt $-for-$ to match public net spending (deficits) ensures that the debt levels will rise when there are deficits.

Rising deficits usually mean declining economic activity (especially if there is no evidence of accelerating inflation) which suggests that the debt/GDP ratio may be rising because the denominator is also likely to be falling or rising below trend.

Further, historical experience tells us that when economic growth resumes after a major recession, during which the public debt ratio can rise sharply, the latter always declines again.

It is this endogenous nature of the ratio that suggests it is far more important to focus on the underlying economic problems which the public debt ratio just mirrors.

Mainstream economics starts with the flawed analogy between the household and the sovereign government such that any excess in government spending over taxation receipts has to be "financed" in two ways: (a) by borrowing from the public; and/or (b) by "printing money".

Neither characterisation is remotely representative of what happens in the real world in terms of the operations that define transactions between the government and non-government sector.

Further, the basic analogy is flawed at its most elemental level. The household must work out the financing before it can spend. The household cannot spend first. The government can spend first and ultimately does not have to worry about financing such expenditure.

However, in mainstream (dream) land, the framework for analysing these so-called "financing" choices is called the government budget constraint (GBC). The GBC says that the budget deficit in year t is equal to the change in government debt over year t plus the change in high powered money over year t. So in mathematical terms it is written as:

gbc

which you can read in English as saying that Budget deficit = Government spending + Government interest payments - Tax receipts must equal (be "financed" by) a change in Bonds (B) and/or a change in high powered money (H). The triangle sign (delta) is just shorthand for the change in a variable.

However, this is merely an accounting statement. In a stock-flow consistent macroeconomics, this statement will always hold. That is, it has to be true if all the transactions between the government and non-government sector have been corrected added and subtracted.

So in terms of MMT, the previous equation is just an ex post accounting identity that has to be true by definition and has not real economic importance.

But for the mainstream economist, the equation represents an ex ante (before the fact) financial constraint that the government is bound by. The difference between these two conceptions is very significant and the second (mainstream) interpretation cannot be correct if governments issue fiat currency (unless they place voluntary constraints on themselves to act as if it is).

Further, in mainstream economics, money creation is erroneously depicted as the government asking the central bank to buy treasury bonds which the central bank in return then prints money. The government then spends this money.

This is called debt monetisation and you can find out why this is typically not a viable option for a central bank by reading the Deficits 101 suite - Deficit spending 101 - Part 1 - Deficit spending 101 - Part 2 - Deficit spending 101 - Part 3.

Anyway, the mainstream claims that if governments increase the money growth rate (they erroneously call this "printing money") the extra spending will cause accelerating inflation because there will be "too much money chasing too few goods"! Of-course, we know that proposition to be generally preposterous because economies that are constrained by deficient demand (defined as demand below the full employment level) respond to nominal demand increases by expanding real output rather than prices. There is an extensive literature pointing to this result.

So when governments are expanding deficits to offset a collapse in private spending, there is plenty of spare capacity available to ensure output rather than inflation increases.

But not to be daunted by the "facts", the mainstream claim that because inflation is inevitable if "printing money" occurs, it is unwise to use this option to "finance" net public spending.

Hence they say as a better (but still poor) solution, governments should use debt issuance to "finance" their deficits. Thy also claim this is a poor option because in the short-term it is alleged to increase interest rates and in the longer-term is results in higher future tax rates because the debt has to be "paid back".

Neither proposition bears scrutiny - you can read these blogs - Will we really pay higher taxes? and Will we really pay higher interest rates? - for further discussion on these points.

The mainstream textbooks are full of elaborate models of debt pay-back, debt stabilisation etc which all claim (falsely) to "prove" that the legacy of past deficits is higher debt and to stabilise the debt, the government must eliminate the deficit which means it must then run a primary surplus equal to interest payments on the existing debt.

A primary budget balance is the difference between government spending (excluding interest rate servicing) and taxation revenue.

The standard mainstream framework, which even the so-called progressives (deficit-doves) use, focuses on the ratio of debt to GDP rather than the level of debt per se. The following equation captures the approach:

debt_gdp_ratio

So the change in the debt ratio is the sum of two terms on the right-hand side: (a) the difference between the real interest rate (r) and the real GDP growth rate (g) times the initial debt ratio; and (b) the ratio of the primary deficit (G-T) to GDP.

The real interest rate is the difference between the nominal interest rate and the inflation rate. Real GDP is the nominal GDP deflated by the inflation rate. So the real GDP growth rate is equal to the Nominal GDP growth minus the inflation rate.

This standard mainstream framework is used to highlight the dangers of running deficits. But even progressives (not me) use it in a perverse way to justify deficits in a downturn balanced by surpluses in the upturn.

The question notes that "some mainstream economists" claim that a ratio of 80 per cent is a dangerous threshold that should not be passed - this is the Reinhart and Rogoff story.

Many mainstream economists and a fair number of so-called progressive economists say that governments should as some point in the business cycle run primary surpluses (taxation revenue in excess of non-interest government spending) to start reducing the debt ratio back to "safe" territory.

Almost all the media commentators that you read on this topic take it for granted that the only way to reduce the public debt ratio is to run primary surpluses. That is what the whole "credible exit strategy" hoopla is about.

Further, there is no analytical definition ever provided of what safe is and fiscal rules such as those imposed on the Eurozone nations by the Stability and Growth Pact (a maximum public debt ratio of 60 per cent) are totally arbitrary and without any foundation at all. Just numbers plucked out of the air by those who do not understand the monetary system.

MMT does not tell us that a currency-issuing government running a deficit can never reduce the debt ratio. The standard formula above can easily demonstrate that a nation running a primary deficit can reduce its public debt ratio over time.

Furthermore, depending on contributions from the external sector, a nation running a deficit will more likely create the conditions for a reduction in the public debt ratio than a nation that introduces an austerity plan aimed at running primary surpluses.

Here is why that is the case.

A growing economy can absorb more debt and keep the debt ratio constant or falling. From the formula above, if the primary budget balance is zero, public debt increases at a rate r but the public debt ratio increases at r - g.

The following Table simulates the two years in question. To make matters simple, assume a public debt ratio at the start of the Year 1 of 100 per cent (so B/Y(-1) = 1) which is equivalent to the statement that "outstanding public debt is equal to the value of the nominal GDP".

Also the nominal interest rate is 1 per cent and the inflation rate is 1 per cent then the current real interest rate (r) is 0 per cent.

If the nominal GDP is growing at -1 per cent and there is an inflation rate of 1 per cent then real GDP is growing (g) at minus 2 per cent.

Under these conditions, the primary budget surplus would have to be equal to 2 per cent of GDP to stabilise the debt ratio (check it for yourself). So, the question suggests the primary budget deficit is actually 1 per cent of GDP we know by computation that the public debt ratio rises by 3 per cent.

The calculation (using the formula in the Table) is:

Change in B/Y = (0 - (-2))*1 + 1 = 3 per cent.

The data in Year 2 is given in the last column in the Table below. Note the public debt ratio has risen to 1.03 because of the rise from last year. You are told that the budget deficit doubles as per cent of GDP (to 2 per cent) and nominal GDP growth shoots up to 4 per cent which means real GDP growth (given the inflation rate) is equal to 3 per cent.

The corresponding calculation for the change in the public debt ratio is:

Change in B/Y = (0 - 3)*1.03 + 2 = -1.1 per cent.

So the growth in the economy is strong enough to reduce the public debt ratio even though the primary budget deficit has doubled.

It is a highly stylised example truncated into a two-period adjustment to demonstrate the point. In the real world, if the budget deficit is a large percentage of GDP then it might take some years to start reducing the public debt ratio as GDP growth ensures.

So even with an increasing (or unchanged) deficit, real GDP growth can reduce the public debt ratio, which is what has happened many times in past history following economic slowdowns.

Economists like Krugman and Mankiw argue that the government could (should) reduce the ratio by inflating it away. Noting that nominal GDP is the product of the price level (P) and real output (Y), the inflating story just increases the nominal value of output and so the denominator of the public debt ratio grows faster than the numerator.

But stimulating real growth (that is, in Y) is the other more constructive way of achieving the same relative adjustment in the denominator of the public debt ratio and its numerator.

But the best way to reduce the public debt ratio is to stop issuing debt. A sovereign government doesn't have to issue debt if the central bank is happy to keep its target interest rate at zero or pay interest on excess reserves.

The discussion also demonstrates why tightening monetary policy makes it harder for the government to reduce the public debt ratio - which, of-course, is one of the more subtle mainstream ways to force the government to run surpluses.
