Introduction:

The magic square, invented by Nicholas KALDOR (1908-1986), to define the 4 main points of the economic policy d´un countries.

At the crossroads between real economy and financial economics, magic square, invented by Nicholas KALDOR (1908-1986), British Economist of post-keynesien current, to define the main points of the economic policy d´un countries.

In 1960, British Economist Nicholas Kaldor speculated to represent by a simple geometric figure the objective of balanced growth.

This representation originally intended to ease the introduction of the “performance” of the economies of the OECD has been a great success and it is designated by the expression of “magic square” to emphasize how the simultaneous achievement of the 4 goals takes the magic.

Utility

C´EST a graphical representation of the four main objectives of conjunctural economic policy of a country are:
* growth,
* the rate of unemployment,
* the external balance of trade balance
* and the stability of prices (inflation)

It is by joining the four points, obtained a quadrilateral representing then of all the more favourable economic situation that this quad is near d´un square.

By connecting four points on each axis, we obtain a quadrangle: more the surface is large, the more the economic health of the country. Important clarification, however: scales of the rates of inflation and the unemployment rate must be reversed, the objectives being to reach 0% on each of these axes (see an example above).

The objectives of the square

The low inflation

Stabilize prices is to avoid inflation and possibly deflation.
If this goal has long was less monitored that full employment is because in closed economy, inflation is not the same observable consequences and open economy. International competition requires the gap of inflation with major trading partners to avoid losing market share.
Domestic inflation does not touch the different components of the population in the same way: holders of fixed income (pensioners including pensioners) and more generally the lenders such as banks, are affected negatively, however those who can borrow and have a wage for example index on prices are winners. Grandpa boomer have for example greatly earned as this.

The construction of economic and Monetary Union has made the fight against inflation the only objective assigned permanently to the European Central Bank. However even if it wants to reduce unemployment it should never say for reasons of efficiency because it is more effective if people think that it is wrong to do but is still as if people think that she is going to do something and the fact.

The macroeconomic inflation target is formula, and is measured in terms of a target value of the general price index, expressed as a percentage of annual increase of it. In the case of the euro area, the target is set at 2% that are considered SAS the ideal rate, so when the inflation rate is close to this threshold, the ECB must take monetary policy measures to reduce the growth of the monetary mass to not feed inflationary pressures.

Full employment

“Full employment” means the lowest possible unemployment rate, because the unemployment rate can not be null.

There are permanent destruction and the creation of jobs and the passage of each other is neither automatic nor immediate. The structures of the productive apparatus and institutions that organize the functioning of the labour market translates into rigidities more or less important that explain the permanent presence of discrepancies between supply and demand for labour.

The incompressible unemployment rate is often referred to as “structural unemployment rate“.

Wanting to have full employment is to seek to bring the effective rate of structural unemployment unemployment rate and try to reduce it as much as it is possible to do so.

Did you know?

Some politicians have sometimes raised the possibility to include the “right to work” in a new declaration of the rights of man (preamble to the Constitution of 1946).

As early as 1945, in the Charter of the United Nations, Member States committed themselves to act, together and individually, to achieve full employment in their respective economies.

In 1992 the Maastricht Treaty in its article 2, provided for mission to the European Community “to promote a[…] high level of employment”.

The Federal Reserve Act, amended in October 1978, defines the mission of the Bank of federal reserve (FED) of the United States of America: “maintain an average growth of monetary aggregates and the amount of credit compatible with the growth potential of production, so as to move towards the following objectives: a rate of maximum employment, stable prices and low long-term interest rates. ” »

If the goal of full employment is displayed by all Governments is for social reasons (taking into account the plight of those who want to work) and economic (do not use all the available work is waste and loss of property be collective).

In France (including Dom), the number of unemployed totalled 3 850 900 in category A (+ 1.1% over one month, + 3.5% year on year) and 5 740 600 for categories A, B, C (+ 0.2% over one month, + 5.3% year on year).

The balance of imports / exports or the balance of trade

A positive trade balance means that the country exports more goods and services than it imports: referred to as “surplus” or “balance surplus. When it is negative, we talk about “trade deficit”.

The balance of trade may be problematic, this is due to the difficulty of the registration of all commercial data. An illustration of this problem is as follows: when all the deficits and trade surpluses are added up, it appears that the world records a trade surplus with itself, by a few points. This may be the case, because all the transactions are either a credit or a debit in the account of each country and should therefore be balanced. An explanation for this phenomenon may lie in transactions to wash dirty money, or other problems yet.

If neither the surplus nor the trade deficit are dangerous for a national economy, they may however be the sign and the cause of other economic problems (in case of deficit: weakness of the industry, overvaluation of the currency promoting goods imported versus indigenous production; or vice versa in case of excess, probable or undervaluation of the currency allowing foreigners to buy low-priced industrial tool of the country).

To assess the situation of a country from the rest of the world (evolution of savings and debt, share capital from abroad or on the contrary abroad…), the balance of trade is not enough: it is a component of the current account, itself part of the balance of payments. So for example a very tourist country can have a deficit trade balance and a positive current balance (if expenditures of tourists pay more than the excess of imports over exports).

Economic relations between residents of the country and the strange country influence the macroeconomic balance. The balance of current transactions translates of inflows or outflows of foreign currency. These movements affect foreign exchange reserves and the formation of the exchange rate. When the value of imports exceeds that of exports (deficit) the national currency is less requested and its price (in foreign currency), that economists call its exchange rate, will drop.

This makes imports more costly if they are paid in foreign currency and on the other hand this reduces the recipe of exports. The results of residents who exchange with non residents are deteriorating.

The factors that may affect the trade balance are as follows:

• Exchange rates;
• the competitiveness of enterprises;
• free trade treaties;
• Customs duties;
• non-tariff barriers at customs;
• relocation or conversely the relocation of domestic firms.

nothing its equilibrium diverges

Point of view of free trade

A trade is mutually beneficial to the partners, and involves an enrichment for both; the words “excess” and “deficit” are therefore inappropriate inasmuch as they respectively imply an enrichment and an impoverishment. They appeared under the mercantilism doctrine that it is better to export goods (acquisition of currency against property) instead of in importer². They have survived by tradition and persistence of the mercantilist (including via Keynesianism) doctrine.

Note that Frédéric Bastiat, the deficit decreased in the period of recession and increases in periods of expansion.

Protectionist perspective

The trade balance deficit is a problem for the State’s economy, it creates unemployment. Need to fix a public policy of protectionism.

The balance of public finances.

If it is impossible that a Government takes lasting more that he spends except by using the windsurfing ticket (so make inflation), a sustainable budget deficit and importantly becomes a handicap. Indeed the State eventually make debt to pay the old debt.

As we must finance the deficit affected Governments must borrow which means that they must pay interest.

If the rate of GDP growth is less than the interest rate, debt increases mechanically (Conversely, if the interest rate is lower than the rate of growth of GDP, the debt decreases automatically).

Politically the Maastricht Treaty and the Amsterdam Treaty require eurozone governments to meet thresholds for all public administrations respectively to 3% for the report of the public deficit to GDP and 60 percent public debt to the GDP report.

Growth

Because economic growth measures the sustainable increase of GDP per capita it is the condition of the improvement of the standard of living if the price increases more slowly than GDP.

So it is the growth of real GDP (GDP purchasing power) that is sought. A higher level of life expands consumer choice and allows changes to lifestyle. In fact amount that represents nothing because the purchasing account. More numerous criteria on the measurement of growth are subject to debate. Indeed it is easy d ‘ show growth strong resulting property (destruction forests, pollution of Lakes etc).

A quick overview of the sources of growth shows that public intervention can contribute to increase the pace.

Should be used more work to produce more and more capital, we speak in this case of extensive growth. Governments can influence the quantity and quality of the available work in amending the legislation on working time. They can form directly from the capital (public investment) and support the investment of the enterprises (low interest rates, grants…)

Another way to increase productivity is to improve the efficiency of labour and capital, referred to as intensive growth (Act on the productivity of labour and capital). Governments can lead training policies, support expenditures for research and development, and innovation.

All recent studies show the strong influence of public investment (education and infrastructure), private investment in particular in information and communication (ICT) technology, structures promoting the mobilization of savings and the stability of prices. See the article devoted to the theories of endogenous growth

But it’s the structural determinants of growth.

Governments may also wish to act on cyclical developments by practicing recovery in the event of recession or stabilization policies when inflation becomes excessive.

The level of redistribution on the basis of the populations also great debate.

Magic square, but why?

This square is called a ‘magical’ car, according to Kaldor, it is impossible to achieve these four goals simultaneously. Indeed, for example, according to the Phillips curve (see another of my articles), it is not possible to simultaneously have an unemployment rate and a low inflation rate, these two attributes being negatively correlated. Growth and unemployment however correlate positively as the disinflation and budgetary l´equilibre.

Politically important

Politically the magic square is very important, because it allows to see who is the big winner in politics. During the Trente Glorieuses, for example, the main purpose of the RFA was to maintain low inflation, while in France the growth and employment were the main objectives. Now we want above all not too d´inflation. This will therefore benefit a certain category of population at the other d´une expense.

Governing is choosing. In a democracy, the public authorities are at the service of the interests expressed by the citizens during the elections. Political power normally strives to act in accordance with this expression by transforming the individual wishes in collective project. It is necessary that the workforce either used with a high employment rate and a low unemployment rate, but also that the price level does not increase too quickly.

It is also a political choice. In theory the right would still be for the fight against inflation. The left preferring the fight against unemployment.

Consequence d´une low inflation:

As for the State and households, the low inflation is bad news for indebted companies. Difficult, even for those who have little debt, maintain their profitability if their turnover has stagnated, due to selling price at half-mast. “Companies are reluctant to invest and hire”, concludes Philippe Waechter, d´ou unable to d´avoir the two elements work for all and low inflation simultaneously. This low inflation however greatly advantage the annuitants (major political force, because pensioners are often retirees). I say that pensioners are often retirees, because have an annuity requires a capital and to create this often asked ud time. The trade balance is rather correct.

Consequence d´une high inflation:

Inflation causes mainly: rising prices and the increase of interest rates (which discourages investment). This affects the value of the currency (the currency depreciation), so in terms of Exchange, we pay with currency more imports and exports reported less. It was a deficit in the trade balance. In general there is growth and declining unemployment.

Unemployment / inflation rate and growth:

More it l´inflation y more growth there or vice versa, more there is growth more prices are increasing. As you’ve surely heard about there is growth we must recruit, who says recruiting said drop in the unemployment rate.

Inflation: the winners

With strong as inflation, employees are very advantaged because inflation is not a bad thing. It allows to reduce the burden of debt and public deficit as well as households, result in wages, so giving back some bargaining power to employees and to transfer wealth from savers to borrowers, old to young people.

Conclusion

Magic square is a very interesting concept and sometimes it was borrowed in management games to simulate the difficulty of the management of a country. Indeed, it is almost impossible d´avoir all the statistics in the Green well qu´il be possible to s´en approach.
