Kinds of income, wages, profit and loss
In a market economy income falls into three groups: income from labour (wage and bonus), income from entrepreneurship (profit) and income from property (dividend, interest, rent). Wages are gross and net: after income tax and other compulsory payments are deducted from the gross wage, what reaches the hand is the net wage. The size of a wage is affected by demand and supply of labour, labour productivity and how well the work matches market demand. Pension, allowance and stipend are special kinds of income given as social support apart from wages. The money received from selling produced goods is called revenue: revenue = quantity of goods sold × price of the goods. An enterprise’s expenses (raw material, wages, energy, rent and so on) are counted; profit = revenue − expenses. If expenses are greater than revenue the enterprise makes a loss: loss = expenses − revenue. Every enterprise aims at profit, so the price of goods is set as cost price plus profit.
Mini-shop: groups estimate the cost of one item (for example a pencil case), set a price and calculate revenue and profit if 10 are sold; then see what happens if only 6 are sold.
