Economics

The rationale for supporting agriculture partly reflects the ‘special case’ nature of the industry itself: agriculture, unlike manufacturing industry, is especially vulnerable to events outside its immediate control. Supply tends to fluctuate erratically from year to year, depending upon such vagaries as the weather and the incidence of pestilence and disease, S

in Fig. 6 (b), significant PRODUCTIVITY improvements associated with farm mechanization, chemical fertilizers and pesticides, etc., have tended to increase supply at a faster rate than demand, from SS to S

in Fig. 6 (b), causing farm prices and incomes to fall (see MARKET FAILURE).

Farming can thus be very much a hit-and-miss affair, and governments concerned with the impact of changes in food supplies and prices (on, for example, the level of farm incomes, the balance of payments and inflation rates) may well feel some imperative to regulate the situation. But there are also social and political factors at work; for example, the desire to preserve rural communities and the fact that, even in some advanced industrial countries (for example, the European Union), the agricultural sector often commands a political vote out of all proportion to its economic weight.

allocative efficiency an aspect of MARKET PERFORMANCE that denotes the optimum allocation of scarce resources between end users in order to produce that combination of goods and services that best accords with the pattern of consumer demand. This is achieved when all market prices and profit levels are consistent with the real resource costs of supplying products. Specifically, consumer welfare is optimized when for each product the price is equal to the lowest real resource cost of supplying that product, including a NORMAL PROFIT reward to suppliers. Fig. 7 (a) depicts a normal profit equilibrium under conditions of PERFECT COMPETITION with price being determined by the intersection of the market supply and demand curves and with MARKET ENTRY/MARKET EXIT serving to ensure that price (P) is equal to minimum supply cost in the long run (AC).

By contrast, where some markets are characterized by monopoly elements, then in these markets output will tend to be restricted so that fewer resources are devoted to producing these products than the pattern of consumer demand warrants. In these markets, prices and profit levels are not consistent with the real resource costs of supplying the products. Specifically, in MONOPOLY markets the consumer is exploited by having to pay a price for a product that exceeds the real resource cost of supplying it, this excess showing up as an ABOVE-NORMAL PROFIT for the monopolist.

Fig. 7 (b) depicts the profit maximizing price-output combination for a monopolist, determined by equating marginal cost and marginal revenue. This involves a smaller output and a higher price than would be the case under perfect competition, with BARRIERS TO ENTRY serving to ensure that the output restriction and excess prices persist over the long run.

Amsterdam Treaty, 1997 a EUROPEAN UNION (EU) statute that extended various provisions of the MAASTRICHT TREATY in the areas of social policy (particularly discriminations against persons and the integration of the SOCIAL CHAPTER), internal procedures for the administration of EU institutions and the EU’s Common Foreign and Security Policy (including defence).

Andean Pact a regional alliance originally formed in 1969 with the general objective of establishing a COMMON MARKET. The current members of the Andean Pact are Peru, Chile, Ecuador, Columbia and Bolivia. By the mid 1980s, however, it had all but collapsed because of various economic and political instabilities. The Pact was relaunched in 1990 minus Chile but with a new member, Venezuela, renewing its commitment to the eventual introduction of a common market. See TRADE INTEGRATION.

annual general meeting (AGM) the yearly meeting of SHAREHOLDERS that JOINT-STOCK COMPANIES are required by law to convene, in order to allow shareholders to discuss their company’s ANNUAL REPORT AND ACCOUNTS, elect members of the BOARD OF DIRECTORS and agree the DIVIDEND payouts suggested by directors. In practice, annual general meetings are usually poorly attended by shareholders and only rarely do directors fail to be re-elected on the strength of PROXY votes cast in favour of the directors. See CORPORATE GOVERNANCE.

annual report and accounts a yearly report by the directors of a JOINT-STOCK COMPANY to the SHAREHOLDERS. It includes a copy of the company’s BALANCE SHEET and a summary PROFIT-AND-LOSS ACCOUNT, along with other information that directors are required by law to disclose to shareholders. A copy of the annual report and accounts is sent to every shareholder prior to the company’s ANNUAL GENERAL MEETING.

annuity a series of equal payments at fixed intervals from an original lump sum INVESTMENT. Where an annuity has a fixed time span, it is termed an annuity certain, and the periodic receipts comprise both a phased repayment of principal (the original lump sum payment) and interest, such that at the end of the fixed term there is a zero balance on the account. An annuity in perpetuity does not have a fixed time span but continues indefinitely and receipts can therefore come only from interest earned. Annuities can be obtained from pension funds or life insurance schemes.

anticipated inflation the future INFLATION rate in a country that is generally expected by business people, trade union officials and consumers. People’s anticipations about the inflation rate will influence their price-setting, wage bargaining and spending/saving decisions. As part of its policy to reduce inflation, governments seek to influence anticipations by ‘talking down’ prospects of inflation, publishing norm percentages for prices and incomes, etc. Compare UNANTICIPATED INFLATION. See EXPECTATIONS, EXPECTATIONS-ADJUSTED/AUGMENTED PHILLIPS CURVE.

anti-competitive agreement a form of COLLUSION between suppliers aimed at restricting or removing competition between them. For the most part, such agreements concentrate on fixing common selling prices and discounts but may also contain provisions relating to market-sharing, production quotas and coordinated capacity adjustments. The main objection to such agreements is that they raise prices above competitive levels, impose unfair terms and conditions on buyers and serve to protect inefficient suppliers from the rigours of competition. In the UK, anti-competitive agreements are prohibited by the COMPETITION ACT 1998. See also RESTRICTIVE PRACTICES COURT.

anti-competitive practice a commercial practice operated by a firm that has the effect of restricting, distorting or eliminating competition (especially if operated by a dominant firm) to the detriment of other suppliers and consumers. Examples of restrictive practices include EXCLUSIVE DEALING, REFUSAL TO SUPPLY, FULL LINE FORCING, TIE-IN SALES, AGGREGATED REBATES, RESALE PRICE MAINTENANCE and LOSS LEADING.

Under the COMPETITION ACT 1980, exclusive dealing, full line forcing, tie-in sales and aggregated rebates can be investigated by the OFFICE OF FAIR TRADING and (if necessary) the COMPETITION COMMISSION and prohibited if found to unduly restrict competition. The RESALE PRICES ACTS 1964, 1976 make the practice of resale price maintenance illegal unless it is, very exceptionally, exempted by the Office of Fair Trading. See also PRICE SQUEEZE.

applied economics the application of economic analysis to real world economic situations. Applied economics seeks to employ the predictions emanating from ECONOMIC THEORY in offering advice on the formulation of ECONOMIC POLICY. See ECONOMIC MODELS, HYPOTHESIS, HYPOTHESIS TESTING.

appreciation 1 an increase in the value of a CURRENCY against other currencies under a FLOATING EXCHANGE-RATE SYSTEM. An appreciation of a currency’s value makes IMPORTS (in the local currency) cheaper and EXPORTS (in the local currency) more expensive, thereby encouraging additional imports and curbing exports, so assisting in the removal of a BALANCE OF PAYMENTS surplus and the excessive accumulation of INTERNATIONAL RESERVES.

How successful an appreciation is in removing a payments surplus depends on the reactions of export and import volumes to the change in relative prices; that is, the PRICE ELASTICITY OF DEMAND for exports and imports. If these values are low, i.e. demand is inelastic, trade volume will not change very much and the appreciation may in fact make the surplus larger. On the other hand, if export and import demand is elastic then the change in trade volumes will operate to remove the surplus, BALANCE-OF-PAYMENTS EQUILIBRIUM will be restored if the sum of export and import elasticities is greater than unity (the MARSHALL-LERNER CONDITION). See REVALUATION for further points. Compare DEPRECIATION 1. See INTERNAL-EXTERNAL BALANCE MODEL. 2 an increase in the price of an ASSET and also called capital appreciation. Assets held for long periods, such as factory buildings, offices or houses, are most likely to appreciate in value because of the effects of INFLATION and increasing site values, though the value of short-term assets like STOCKS can also appreciate. Where assets appreciate, then their REPLACEMENT COST will exceed their HISTORIC COST, and such assets may need to be revalued periodically to keep their book values in line with their market values. See DEPRECIATION 2, INFLATION ACCOUNTING.

APR the ‘annualized percentage rate of INTEREST’ charged on a LOAN. The APR rate will depend on the total ‘charge for credit’ applied by the lender and will be influenced by such factors as the general level of INTEREST RATES, and the nature and duration of the loan.

Where lenders relate total interest charges on INSTALMENT CREDIT loans to the original amount borrowed, this can give a misleading impression of the interest rate being charged, for as borrowers make monthly or weekly repayments on the loan, they are reducing the amount borrowed, and interest charges should be related to the lower average amount owed. For example, if someone borrows £1,000 for one year with a total credit charge of £200, the ‘simple interest’ charge on the original loan is 20%. However, if the loan terms provide for monthly repayments of £100, then at the end of the first month the borrower would have repaid a proportion of the original £1,000 borrowed and by the end of the second month would have repaid a further proportion of the original loan, etc. In effect, therefore, the borrower does not borrow £1,000 for one whole year but much less than this over the year on average, as he or she repays part of the outstanding loan. If the total credit charge of £200 were related to this much smaller average amount borrowed to show the ‘annualized percentage rate’, then this credit charge would be nearer 40% than the 20% quoted.

To make clear to the borrower the actual charge for credit and the ‘true’ rate of interest, the CONSUMER CREDIT ACT 1974 requires lenders to publish both rates to potential borrowers.

a prioriadj. known to be true, independently of the subject under debate. Economists frequently develop their theoretical models by reasoning, deductively, from certain prior assumptions to general predictions.

For example, operating on the assumption that consumers behave rationally in seeking to maximize their utility from a limited income, economists’ reasoning leads them to the prediction that consumers will tend to buy more of those products whose relative price has fallen. See ECONOMIC MAN, CONSUMER EQUILIBRIUM

arbitrage the buying or selling of PRODUCTS, FINANCIAL SECURITIES or FOREIGN CURRENCIES between two or more MARKETS in order to take profitable advantage of any differences in the prices quoted in these markets. By simultaneously buying in a low-price market and selling in the high-price market a dealer can make a profit from any disparity in prices between them, though in the process of buying and selling the dealer will add to DEMAND in the low-price market and add to SUPPLY in the high-price market, so narrowing or eliminating the price disparity. See SPOT MARKET, FUTURES MARKET, COVERED INTEREST ARBITRAGE.

arbitration a procedure for settling disputes, most notably INDUSTRIAL DISPUTES, in which a neutral third party or arbitrator, after hearing presentations from all sides in dispute, issues an award binding upon each side. Arbitration is mostly used only as a last resort when normal negotiating proceedings have failed to bring about an agreed settlement. In the UK, the ADVISORY CONCILIATION AND ARBITRATION SERVICE (ACAS) acts in this capacity. See MEDIATION, COLLECTIVE BARGAINING, INDUSTRIAL RELATIONS.

arc elasticity a rough measure of the responsiveness of DEMAND or SUPPLY to changes in PRICE, INCOME, etc. In the case of PRICE ELASTICITY OF DEMAND, it is the ratio of the percentage change in quantity demanded (Q) to the percentage change in price (P) over a price range such as P

to P

in Fig. 8. Arc elasticity of demand is expressed notationally as:

where P

= original price, Q

= original quantity, P

= new price, Q

= new quantity. Because arc elasticity measures the elasticity of demand (e) over a price range or arc of the demand curve, it is only an approximation of demand elasticity at a particular price (POINT ELASTICITY). However, the arc elasticity formula gives a reasonable degree of accuracy in approximating point elasticity when price and/or quantity changes are small. See also ELASTICITY OF DEMAND.

articles of association the legal constitution of a JOINT-STOCK COMPANY that governs the internal relationship between the company and its members or SHAREHOLDERS. The articles govern the rights and duties of the membership and aspects of administration of the company. They will contain, for instance, the powers of the directors, the conduct of meetings, the dividend and voting rights assigned to separate classes of shareholders, and other miscellaneous rules and regulations. See MEMORANDUM OF ASSOCIATION.
