ok firstly, you start by finding a gun. then kill all the other markets competitors. now you own the markets :)
In a perfectly competitive market, marginal revenue is equal to price.
In a perfectly competitive market, the price is equal to the marginal revenue.
Yes, in a perfectly competitive market, marginal revenue equals price.
To determine the method for finding marginal revenue in a perfectly competitive market, one can calculate the change in total revenue when one additional unit of output is sold. This can be done by taking the derivative of the total revenue function with respect to quantity. In a perfectly competitive market, marginal revenue is equal to the market price.
Yes, in a perfectly competitive market, the marginal revenue is equal to the price of the good for each unit sold.
The shape of the marginal social benefit curve in a market economy is determined by factors such as consumer preferences, externalities, government regulations, and the availability of substitutes.
In a perfectly competitive market, it is equal to marginal cost, it is also the point of equilibrium.
One can determine the socially efficient quantity in a market by finding the point where the marginal social benefit equals the marginal social cost. This is where the overall benefit to society is maximized and resources are allocated efficiently.
Since, in a perfectly competitive market, prices are fought down to Price = Marginal Cost, the only way to make a strict economic profit is to lower marginal cost.
It is possible for perfectly competitive markets to be inefficient when externalities are present. Externalities arise when an economic activity has an unintended impact on other economic agents and/or the market. This results in there being a socially optimal level of production that does not coincide with the privately determined equilibirum level of production derived from the supply and demand curves (which, respectively, represent the marginal private costs and marginal private benefits to producers and consumers). With respect to the efficiency of markets, positive externalities result in too little of the good in question being produced. In this case, the market equilibrium is lower than desired (the marginal social benefit curve lies above the marginal private benefit [demand] curve). In this case, the efficient market outcome would occur where the marginal social beneift curve interests the marginal private cost (supply) curve. When negative externalities occur, too much of the good in question is being produced. This results in the supply curve, which represents the marginal private costs of production, lying below the marginal social cost curve because the private cost curve fails to take into account the costs of production incurred by all of society. In this case, the efficient market outcome would occur where the marginal social cost curve coincides with the private marginal benefit (demand) curve.
To determine the allocatively efficient quantity in a market, one must find the point where the marginal cost of production equals the marginal benefit to consumers. This occurs when resources are allocated in a way that maximizes overall societal welfare.
One primary advantage of government intervention is to market failure just like when the marginal social cost is greater than the marginal social benefit or vise versa. One disadvantage is that the market may become dependent on subsidies if they are used to correct failure.
