Section F: Supply of Goods and Services (Q101-Q120)

99. Specialisation is where an individual, firm, or country concentrates its productive efforts in a particular area where it has the greatest comparative advantage. 100. The three stages of production are: primary (extraction of raw materials), secondary (changing raw materials into finished goods), and tertiary (distribution of finished goods). 101. Supply is defined as the quantities of goods and services that producers are willing and able to offer for sale at various prices during a specified period of time, all other things being equal (or ceteris paribus). 102. The law of supply states that there is a direct (or positive) relationship between the price of a good and the quantity supplied. 103. According to the law of supply, as the price of a commodity rises, the quantity supplied rises (or increases), all other things being equal. 104. A supply schedule is a table that shows the quantity supplied at different prices. 105. The supply curve is upward sloping from left to right, indicating that higher prices lead to higher quantities supplied. 106. In the general supply function Qs = c + dPx, the positive sign before 'd' shows that price and quantity supplied are directly (or positively) related. 107. Joint supply occurs when the production of one good automatically leads to the supply of another good (or by-product), for example, palm oil and palm kernel. 108. Competitive supply exists when two goods require the use of the same factors of production, so that an increase in supply of one leads to a decrease in supply of the other. 109. Complementary supply (also called composite supply) exists when a commodity can be supplied from many sources. 110. Derived supply refers to the quantity of a good produced because of the demand for another related good. 111. The law of diminishing marginal returns is the main factor that explains the upward slope of the supply curve. 112. Market supply is the horizontal summation of all individual supply curves for a particular commodity. 113. Aggregate supply is the sum of all the individual (or firm) supplies of various commodities in an economy. 114. An increase in the profit margin acts as an incentive for producers to increase the quantity supplied at higher prices. 115. Ghana is one of the world's leading producers of cocoa beans, a major agricultural export commodity. 116. The law of supply assumes ceteris paribus, meaning that factors such as technology, input prices, taxes, subsidies, and expectations remain constant. 117. In a supply function Qs = 50 + 0.25P, if P = GH¢120, the quantity supplied is units. Step 1: Substitute the given price into the supply function. Qs = 50 + 0.25P Qs = 50 + 0.25(120) Step 2: Perform the multiplication. Qs = 50 + 30 Step 3: Perform the addition. Qs = 80 The quantity supplied is 80 units.
