of the DWP’s agency Jobcentre Plus and its nationwide network of JOB CENTRES, the introduction of the jobseekers allowance as a replacement for unemployment benefit and the NEW DEAL programme aimed at reducing youth unemployment and long-term unemployment amongst older workers.

      The DWP is also responsible for conducting the fact-finding LABOUR FORCE SURVEY, which provides data on conditions in the labour market, for overseeing the application of the UK’s EMPLOYMENT LAWS, and for implementing employee rights’ regulations issued by the European Union (see, for example, the WORKING TIME REGULATION).

      Department of Health (DoH) the UK government department responsible for administering the National Health Service.

      Department of Social Security see DEPARTMENT FOR WORK AND PENSIONS.

      department store a large RETAIL OUTLET. Department stores may be under single-shop ownership or run as a multiple CHAIN STORE business. Unlike most other retailers, who tend to specialize in relatively narrow ranges of products, the essential characteristic of a department store is the great variety of products it stocks: ‘everything under one roof’. See RETAILER, DISTRIBUTION CHANNEL.

      Department of Trade and Industry (DTI) the UK government office that is primarily responsible for implementing and administering the government’s industrial and trade policies. A particular concern at the DTI is the promotion of greater efficiency through an INDUSTRIAL POLICY programme that includes support for new business start-ups, consultancy services for small firms, research and development, and technology transfer. In the past, the DTI has been required by governments to involve itself in the rationalization of declining industries and support for ‘failing’ firms, but at the present time the emphasis is very much on fostering greater ‘enterprise’ by business itself with a minimum of direct state intervention. See SMALL BUSINESS SERVICE, BUSINESS LINK.

      The DTI is responsible for the operation of REGIONAL POLICY, vetting applications for regional selective assistance by firms investing in ASSISTED AREAS. The DTI works closely with the OFFICE OF FAIR TRADING in matters affecting COMPETITION POLICY; the DTI regulates the formation of companies and their conduct, through the COMPANY REGISTRAR, and is responsible for issuing licences to deposit-taking institutions and authorizing dealers in stocks and shares, etc. (see FINANCIAL SERVICES ACT 1986). Finally, the DTI plays a prominent part in the running of the UK’s overseas trade and investment affairs, representing the country’s interests at international (WORLD TRADE ORGANIZATION) and regional levels (EUROPEAN UNION). The DTI is important in the promotion of exports and foreign investment through the TRADE PARTNERS network and related back-up facilities and services including the EXPORT CREDIT GUARANTEE DEPARTMENT.

      dependent variable a variable that is affected by some other variable in a model. For example, the demand for a product (the dependent variable) will be influenced by its price (the INDEPENDENT VARIABLE). It is conventional to place the dependent variable on the left-hand side of an EQUATION. See DEMAND FUNCTION, SUPPLY FUNCTION.

      deposit account or time account or savings account an individual’s or company’s account at a COMMERCIAL BANK into which the customer can deposit cash or cheques and from which he or she can draw out money subject to giving notice to the bank. Deposit accounts (unlike CURRENT ACCOUNTS, which are used to finance day-to-day transactions) are mainly held as a form of personal and corporate SAVING and used to finance irregular ‘one-off’ payments. INTEREST is payable on deposit accounts, normally at rates above those paid on current accounts, in order to encourage clients to deposit money for longer periods of time. Unlike with a current account, cheques cannot generally be drawn against deposit accounts. See BANK DEPOSIT.

       depreciation

      1 a fall in the value of a CURRENCY against other currencies under a FLOATING EXCHANGE-RATE SYSTEM, as shown in Fig. 43 (a). A depreciation of a currency’s value makes IMPORTS (in the local currency) more expensive and EXPORTS (in the local currency) cheaper, thereby reducing imports and increasing exports, and so assisting in the removal of a BALANCE OF PAYMENTS deficit. For example, as shown in Fig. 43 (b), if the pound-dollar exchange rate depreciates from £1.60 to £1.40, then this would allow British exporters to reduce their prices by a similar amount, thus increasing their price competitiveness in the American market (although they may choose not to reduce their prices by the full amount of the depreciation in order to boost profitability or devote more funds to sales promotion, etc.) By the same token, the depreciation serves to raise the sterling price of American products imported into Britain, thereby making them less price-competitive than British products in the home market.

      In order for a currency depreciation to ‘work’, four basic conditions must be satisfied:

      (a) how successful the depreciation is depends on the reactions of export and import volumes to the change in relative prices, i.e. the PRICE ELASTICITY OF DEMAND for exports and imports. If these volumes are low, i.e. demand is inelastic, trade volumes will not change much and the depreciation may in fact worsen the situation. On the other hand, if export and import demand is elastic then the change in trade volume will improve the payments position. Balance-of-payments equilibrium will be restored if the sum of export and import elasticities is greater than unity (the MARSHALL-LERNER CONDITION);

      (b) on the supply side, resources must be available, and sufficiently mobile, to be switched from other sectors of the economy into industries producing exports and products that will substitute for imports. If the economy is fully employed already, domestic demand will have to be reduced and/or switched by deflationary policies to accommodate the required resource transference;

      (c) over the longer term, ‘offsetting’ domestic price, rises must be contained. A depreciation increases the cost of essential imports of raw materials and foodstuffs, which can push up domestic manufacturing costs and the cost of living. This in turn can serve to increase domestic prices and money wages, thereby necessitating further depreciations to maintain price competitiveness;

      (d) finally, a crucial requirement in underpinning the ‘success’ of the above factors and in maintaining long-run equilibrium is for there to be a real improvement in the country’s industrial efficiency and international competitiveness. (See ADJUSTMENT MECHANISM entry for further discussion.) See BALANCE-OF-PAYMENTS EQUILIBRIUM, INTERNAL-EXTERNAL BALANCE MODEL, PRICE ELASTICITY OF SUPPLY. Compare APPRECIATION 1.

      2 the fall in the value of an ASSET during the course of its working life. Also called amortization. The condition of plant and equipment used in production deteriorates over time, and these items will eventually have to be replaced. Accordingly, a firm is required to make financial provision for the depreciation of its assets.

      Depreciation is an accounting means of dividing up the historic cost of a FIXED ASSET over a number of accounting periods that correspond with the asset’s estimated life. The depreciation charged against the revenue of successive time periods in the PROFIT-AND-LOSS ACCOUNT serves to spread the original cost of a fixed asset, which yields benefits to the firm over several trading periods. In the period end BALANCE SHEET, such an asset would be included at its cost less depreciation deducted to date. This depreciation charge does not attempt to calculate the reducing market value of fixed assets, so that balance sheets do not show realization values.

      Depreciation formulas base the depreciation charge on the HISTORIC COST of fixed assets. During a period of INFLATION, however, it is likely that the REPLACEMENT COST of an asset is likely to be higher than its original cost. Thus, prudent companies need to
