As Northern Ireland's capital city, Belfast is host to the Northern Ireland Assembly at Stormont, the site of the devolved legislature for Northern Ireland. Belfast is divided into four Northern Ireland Assembly and UK parliamentary constituencies: North Belfast, West Belfast, South Belfast and East Belfast.
Fixed Costs, Variable Costs, and Total Costs z Fixed costs are those that are spent and cannot be changed in the period of time under consideration. z In the long run there are no fixed costs since all costs are variable. z In the short run, a number of costs will be fixed. Fixed Costs, Variable Costs, and Total Costs z Workers represent variable costs â those that change as output changes. Fixed Costs, Variable Costs, and Total Costs z The sum of the variable and fixed costs are total costs. TC = FC + VC Average Costs z Much of the firmâs discussion is of average cost.
The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost (MC) indicates how much total cost changes for a given change in the quantity of output.Because changes in total cost are matched by changes in total variable cost in the short run (total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost.f marginal revenue equals marginal cost, then the firm produces the profit-maximizing output quantity. If marginal revenue is less than marginal cost, then it can boost profit by increasing production. If marginal revenue is greater than marginal cost, then it can boost profit by decreasing production.
