The Internet has many places to ask questions about anything imaginable and find past answers on almost everything.

## What is the socially optimal level of output?

The output level that reflects all the costs and benefits associated with a transaction i.e. it is the equilibrium that would be achieved if the market outcome reflects the effect of externalities.

## What is the socially optimal quantity?

The socially optimal level of consumption of any good or service occurs where the benefit to the user of the last unit consumed (ie, the MPB) is no more and no less than the total cost borne by society when that unit is consumed (ie, the MSC).

## What is the efficient ie socially optimal level of production?

When output occurs at the intersection of marginal social benefit (MSB) and marginal social cost (MSC), the socially optimal level of output is achieved. Also known as the allocatively efficient level of output. If output occurs at any other level, a market failure exists.

## How do you calculate socially efficient quantity?

The socially efficient quantity can be attained by taxing each firm an amount equal to (1/12)*192 = \$16 per lift ticket so that firms will now consider the external effect when determining their output level.

## What is Allocatively efficient quantity?

The allocatively efficient quantity of output, or the socially optimal quantity, is where the demand equals marginal cost, but the monopoly will not produce at this point. Instead, a monopoly produces too little output at too high a cost, resulting in deadweight loss.

## What is the socially efficient outcome?

Socially efficient market outcomes are the optimal distribution of all resources in society while taking into account all internal and external costs and benefits. In our study of economics, socially efficient takes place where marginal social benefit (MSB) = marginal social cost (MSC).

## What does social efficiency mean?

Social efficiency means taking into account all of the private and social costs and benefits of a decision / policy. Social welfare is optimised when marginal social benefit = marginal social cost.

## Why is monopoly not efficient?

Monopoly is inefficient because it has market control and faces a negatively-sloped demand curve. As a profit-maximizing firm that equates marginal revenue with marginal cost, the price charged by monopoly is greater than marginal cost. The inequality between price and marginal cost is what makes monopoly inefficient.

## Are monopolies dynamically efficient?

Monopolists can also be dynamically efficient – once protected from competition monopolies may undertake product or process innovation to derive higher profits, and in so doing become dynamically efficient. Because of barriers to entry, a monopolist can protect its inventions and innovations from theft or copying.

## Are monopolies always bad for society?

Monopolies over a particular commodity, market or aspect of production are considered good or economically advisable in cases where free-market competition would be economically inefficient, the price to consumers should be regulated, or high risk and high entry costs inhibit initial investment in a necessary sector.
