Answer:
The answer is: b
Explanation:
In long-run equilibrium, the long run aggregate demand curve and aggregate supply curve intersect where the marginal revenue (revenue derived from selling an additional unit) and marginal cost (cost incurred from producing) an additional unit) are equal. In the long-run equilibrium, this intersection occurs at the lowest point of the long-run average total cost curve (curve depicting the average cost per unit of production).
Holding all else constant, short run changes in the economy would not change the potential output levels. The long-run aggregate supply curve would remain fixed at the potential level of output. However, these changes: international tensions, corporate scandals and loss of confidence in policymakers would cause shifts in the aggregate demand curve since demand would be adversely affected.
Consumer confidence is the perspective or outlook that consumers have on the state of the economy. The destabilising factors given in this scenario would raise the levels of uncertainty and perceived risk, reducing the confidence levels of consumers and ultimately resulting in reduced demand. In long-run equilibrium, when demand is reduced, it is indicated by a leftward shift in the aggregate demand curve.
Answer:
The answer is in a perfect competition profit is maximized when marginal cost equal marginal revenue and price is equal to average revenue and marginal revenue, while in monopolist profit is maximized when marginal cost is equal to marginal revenue.
Explanation:
The firm in a perfectly competitive market is a price taker,the price in the market is determined by the market forces of demand and supply. The firm has to sell their product at the ruling market price.The demand curve facing the firm in perfectly competitive market is horizontal or perfectly elastic, profit is therefore maximized when the marginal cost is equal to average revenue and marginal revenue. The firm in the market operate at the output level in which the price and marginal revenue is equal to marginal cost. Whatever prices that change the market demand or supply will change the demand curve faced by the firm.The firm cannot do anything to this than to accept the market price and the demand curve.
In a monopoly the demand curve is identical to the demand curve of the firm, because industry demand curve is downward sloping.The monopolist can either set the price or quantity not the two.when one is determined the value of the other will be determined by the demand function. The profit maximization of the monopolist also requires that marginal cost must be equal to marginal revenue just like in the case of perfect completion.when the monopolist equates MR and MC the monopolist determines its output and the market price for the product. The revenue curve is steeper than the demand curve,because the straight line is the market demand. The firm will have to reduce The price of the product if they want to sell more of their product the unit of the product sold is the AR which is equal to the price.Therefore the AR curve of the monopolist and the perfect competition MR and AR are both identical that informed the reason why the marginal revenue curve is steeper than the demand curve for a single price monopolist.
Steel was important to the second industrial revolution majorly because of its properties and its potential uses. Because steel is very strong, light and cheap, it was found ideal for many purposes. Steel was used to make many of the new inventions that characterized that period, a good example of this is rail road.
Answer:
a.
Net Exports 2015 are - $471.4 billion.
b.
Net Exports 2016 are - $552.1 billion.
Explanation:
The net exports for a country is the difference between the value of exports and the value of imports of a country over a certain period of time. The amount of net exports can be wither positive or negative depending upon the value of exports being in excess of the value of imports or not. The formula for net exports is,
Net Exports = Value of Exports - Value of Imports
a.
Net Exports for 2015 = 2344 - 2815.4
Net Exports for 2015 = - $471.4 billion
b.
Net Exports for 2016 = 2372.7 - 2924.8
Net Exports for 2016 = - $552.1 billion
