Macroeconomics Gross national product The total money value of all final goods and services produced in an economy in one year, plus net property income from abroad (interest, rent, dividends and profit). (Profits from MNCs) GNP=GDP + net property income (GNP=GDP + net investment earnings) GNP>GDP in Switzerland GDP>GNP in Brazil Net national product GNP [the total money value of all GNP – depreciation =NNP final goods and services produced in an economy in one year, plus net property income from abroad (interest, rent, dividends and profit)] minus depreciation (capital consumption). Nominal GDP The total money value of all final goods and services produced in an economy in one year, not adjusted for inflation. Real GDP the total money value of all final goods and services produced in an economy in one year, adjusted for inflation. RGDP = NGDP/GDP deflator 5 Per capita GDP The total money value of all final goods and services produced in an economy in one year per head of the population. Aggregate demand* The total spending in an economy Increased AD causes consisting of consumption, inflation if the economy is investment, government at full employment. expenditure and net exports.

Demand-side policy Government policy designed to Fiscal and /or monetary influence the aggregate demand in policies to boost AD after the economy, thus affecting the GFC in 2008. average price level and real national output. Fiscal policy Demand-side policy using changes in government spending and/or direct taxation to achieve economic objectives relating to inflation and unemployment. Monetary policy Demand-side policy using changes in the money supply or interest rates to achieve economic objectives relating to inflation and unemployment. Aggregate supply* The total amount of domestic goods and services supplied by businesses and the government, including both consumer goods and capital goods. Short run aggregate supply (SRAS Aggregate supply that varies with the level of demand for goods and services and that is shifted by changes in the costs of factors of production. Long run aggregate supply (LRAS GDP/population Countries with rapid popn growth need to have more rapid increase in GDP (Kenya, Egypt) GW Bush 2008 $600bn tax rebates, Obama 2009 $1.2 trillion in increased G spending (“fiscal stimulus”) Trump tax cuts despite $21 trillion national debt “QE” Quantitative Easing” by the US Fed, B of E, BoJ.

The short run AS curve is drawn given some nominal variables such as the nominal wage rate, which is assumed fixed in the short run. Aggregate supply that is In the neoclassical long dependent upon the resources in run, on the other hand, the 6 the economy and that can only be increased by improvements in the quantity and/or quality of factors of production. Supply-side policies nominal wage rate varies with economic conditions. (High unemployment leads to falling nominal wages and restores full employment.) Hence in the long run the aggregate supply curve is vertical. Government policies designed to These can be « market shift the long run aggregate supply based » (Chicago) or curve to the right, thus increasing « interventionist » potential output in the economy. (Swedish model. » Market based Supplyside policies Policies to allow the free market to function without government restrictions.

Unemployment Rate # unemployed/labour force #unemployed/ employed +unemployed Full employment Exists when the number of jobs available in an economy is equal to or greater than the number of people actively seeking work. Underemployment When workers are carrying out jobs for which they are overqualified, not using their full skills and abilities or when they are working part-time but wishing more hours.

Switching jobs Falling AD. Disequilibrium unemployment that exists when there is insufficient aggregate demand in the economy. Wages in the economy get pushed up above the equilibrium wage rate, either by the government or by trades unions. Made worse if wages are « downwardly sticky. » U > 25% in Greece and Spain after 2008 GFC. Minimum wage laws: USA $7.25 per hour, $10 or $15 proposed. France SMIC €1450 per month. A sustained increase in the general Zimbabwe 76bn % in one (or average) level of prices and a month 2008 ! fall in the value of money. Inflation that is caused by Increased wages in China increasing aggregate demand in an economy, i.e. a shift of the AD curve to the right. Iinflation that is caused by an 1970s oil shocks, increase in the costs of production « stagflation » in an economy, i.e. a shift of the SRAS curve to the left. A persistent fall in the average Japan. level of prices in an economy. Greece since 2008 (malign fall in AD) Switzerland (benign?) after appreciation. A curve showing an inverse Under President Reagan relationship between the and Prime Minister rate of unemployment and Margaret Thatcher in the the rate of inflation, which 1980s there was a decline suggests a trade-off in inflation, but at the cost between inflation and of a big rise in unemployment (short run unemployment. Phillips curve). The vertical long run Phillips curve shows the monetarist view that there is no trade-off between inflation and unemployment in the long run and that there exists a natural rate of unemployment that can only be affected by supplyside policies. 8 Natural rate of unemployment (HL only)* The rate of unemployment that is consistent with a stable rate of inflation. It is the rate where the long run Phillips curve touches the x-axis. Direct taxation Taxation imposed on people’s income or wealth, and on firms’ profits. Indirect taxation Tax on expenditure. It is added to the selling price of a good or service. It is sometimes known as sales tax. Progressive taxation – Direct taxation where tax is levied at an increasing rate for successive bands of income. The marginal tax rate is higher than the average tax rate. Excludes cyclical U. Can be altered by supply side reforms like increased flexibility of labour market. Estimated NRU: USA 5%, France 9%, Switz 3%. Top tax rates: Belgium 64%, Sweden 60%, USA 56% (Fed+state+local) Japan 50% UK 45% S Africa 42% Russia 13% (flat) UAE 0% VAT rates : France 20% Greece 23% UK 20% Switzerland 8% Francois Hollande proposed a top marginal tax rate of 75% on earnings over €1m but it was not introduced.

Transfer payments A payment received for which U benefits, old age no good or service is pensions, family allowance. exchanged, e.g. a student grant or a pension. Laffer Curve (HL only) A curve showing the possible relationship between income tax rates and the total tax revenue received by the government. Lorenz Curve A curve showing distribution of the total income in the economy. It is calculated in cumulative terms. The Implies high marginal income tax rates might reduce tax revenue. High taxes have disincentive effect and increase tax evasion. 9 further the curve is from the line of absolute equality (45 degree line), the more unequal is the distribution of income. Gini coefficient Measures the ratio of the Gini coefficients : area between a Lorenz curve and the line of absolute equality to the total area under the line of equality. The higher the figure, the more unequal is the distribution. SECTION 3 INTERNATIONAL ECONOMICS Free trade – international trade that takes place without any barriers, such as tariffs, quotas, or subsidies. Free trade International trade that takes Trade within the EU. place without any barriers, FTA between China and such as tariffs, quotas, or Switzerland. subsidies. Tariff* A duty (tax) that is placed GW Bush 35% tariff on upon imports to protect imported steel. domestic industries from foreign competition and to raise revenue for the government. Quota* Import barriers that set limits on the quantity or value of imports that may be imported into a country. Subsidy* Voluntary export restraint (VER) Swiss wine producers were once protected by a quota on imported wine. (Also limits on meat imports from cross-border shopping.) An amount of money paid by China is accused of unfair the government to a firm, per subsidies to steel firms. unit of output, to encourage output and to give the firm an advantage over foreign competition. A voluntary agreement between an exporting country and an importing country that limits the volume of trade in a particular product (or products). 1980s Japan agreed to reduce car exports to USA. 10 Infant industry argument The argument that new industries should be protected from foreign competition until they are large enough to achieve economies of scale that will allow them to be competitive. Indian car industry protected for 50 years. (Result was little progress and no competition for Ambassador car.) Dumping It is the selling of a good in another country at a price below its unit cost of production. China accused of dumping steel, solar panels. EU dumping agricultural surplus (sugar). Anti-dumping Legislation to protect an economy against the importing of a good at a price below its unit cost of production. Anti-dumping duties on Chinese solar panels by EU and USA. (But maybe China has absolute and comparative advantage?) Free trade area (FTA) An agreement made NAFTA (USA, Canada, between countries, where the Mexico) increased trade countries agree to trade between them. freely among themselves, but are able to trade with countries outside the free trade area in whatever way they wish. Customs union An agreement made When UK joined the EEC between countries, where the tariffs were imposed on countries agree to trade dairy produce from NZ. freely among themselves, and they also agree to adopt common external barriers against any country attempting to import into the customs union. Common market A customs union with 1957 EEC meant Italians common policies on product could migrate freely to regulation, and free Germany for work. movement of goods, services, capital, and labour. Trade creation (HL only) Occurs when the entry of a USA importing more from country into a customs union Mexico. or FTA leads to the production of a good moving from a high-cost producer to a low-cost producer. Trade diversion (HL only) Occurs when the entry of a UK importing butter from country into a customs union Denmark instead of NZ. leads to the production of a 11 good moving from a low-cost producer to a high-cost producer.

Invisible balance Expenditure-switching policies Expenditure-reducing policies Marshall-Lerner condition (HL only) Set up at end of Uruguay Round of GATT talks 1994. 2001 start of Doha Development Round, minor progress made in 2013, Bali, but talks not concluded. Policies implemented by the government that attempt to switch the expenditure of domestic consumers away from imports towards domestically produced goods and services Policies implemented by the government that attempt to reduce overall expenditure in the economy, including expenditure on imports. Protectionism: 35% tariffs on imported steel to help US Steel (GW Bush 2001) Depreciation: “currency manipulation” by China and Japan. States that a depreciation, or devaluation, of a currency will only lead to an improvement in the current account balance if the elasticity of demand for exports plus the CAB of UK and Italy improved after depreciation in 1992 (“Black Wednesday”.) However Swiss CAB improved after appreciation Causes recession by reducing AD! 12 elasticity of demand for as PED for M and X is imports is greater than one. inelastic. J-Curve (HL only Suggests that in the short UK 1992-94 term, even if the MarshallLerner condition is fulfilled, a fall in the value of the currency will lead to a worsening of the current account deficit, before things improve in the long term. Terms of trade An index that shows the value of a country’s average export prices relative to their average import prices. Deteriorating terms of trade/adverse terms of trade Where the average price of exports falls relative to the average price of imports. Also called “unfavourable movement.” Index of export prices/index of import prices X 100 =ToT index. Swiss ToT improves if oil prices fall. LEDCs exporting primary products (commodities) have often suffered from falling prices (Ethiopian coffee.) Elasticity of demand for exports The responsiveness of the quantity demanded of exports when there is a change in the price of exports. Demand for Japanese cars is relatively elastic (substitutes) so depreciation of Yen will increase export revenue. Elasticity of demand for imports The responsiveness of the Demand for oil in Europe is quantity demanded of inelastic so a fall in oil prices exports when there is a will improve CAB. change in the price of exports. Section 4 Development Economics Poverty cycle A circular chain of events starting and ending in poverty, such as low income means low savings means low investment means low growth means low incomes. Infrastructure The large scale public Roads, railways, sanitation, systems, services, and ports, electricity supply facilities of a country that are necessary for economic activity. They are accumulated through investment, usually by the government. 13 Indebtedness Relates to the high levels of HIPCs (highly indebted poor debt that developing countries) have been given countries owe to developed Conditional Debt Relief. countries.

Export-led growth (outward-oriented strategies) Strategies based on Hong Kong, Singapore, S openness and increased Korea, Malaysia international trade. Growth is achieved by concentrating on increasing exports, and export revenue, as a leading factor in the AD of the economy.
