Suppose that Sally's initial weekly demand (Dl), marginal cost (MC), marginal revenue (MRI), and average total cost (ATC) curves are as shown in the graph in Tab 1. The profit-maximizing quantity of bracelets that Sally should produce and sell is bracelets. The price she should charge her customers is $0 (Do NOT press Enter after typing the answer in each cell.

Now suppose that Sally undertakes an aggressive social media campaign and increases her presence online, gaining a significant number of customers. Her new demand curve, D2, results in a new marginal revenue curve, MR2, shown in Tab 2.

Which of the following is not a characteristic of monopolistic competition?
The products are standardized
A group of competing companies that aim to maximize joint profits by coordinating their policies to fix prices, manipulate output, or restrict competition is called a
cartel
A situation in which decision makers coordinate their actions to achieve a desired outcome describes:

The difference between the economic surplus when the market is at its competitive equilibrium and the economic surplus when the market is not in equilibrium is the:

Profit maximization implies that monopolistically competitive firms should expand production up to the point where the marginal revenue equals the marginal cost.

The characteristics of an oligopoly market are:

The Sherman Act of 1890
made "every contract, combination, or conspiracy in restraint of trade" illegal.
To maximize profits, a cartel should produce a level of output where the revenue equals the cost.

One common feature of competitive markets is that firms invest heavily in product development and innovation, which benefits greatly.

A manufacturer's profits are determined not only by its decisions but also by the decisions of the other firms in the industry. This is why we say that oligopolistic firms are:

Given that oligopolistic firms face other competitors in their markets, their behaviour must definitely be

Which of the following prohibits mergers that would substantially lessen competition or create a monopoly,
the clayton act
Oligopolistic firms tend to price above their marginal and average total costs of production and are not subject to the intense competitive pressures. As a result,
the equilibrium output produced by an oligopolistic firm is neither allocatively nor productively efficient.

Which of the following aspects of oligopolistic firms does game theory help us study?

Laws designed to prevent firms from engaging in behaviors that would lessen competition in a market are called
antitrust
Two members of a criminal gang, George and Randy, are arrested and imprisoned. Each prisoner is in solitary confinement with no means of speaking to or exchanging messages with the other. The prosecutors do not have enough evidence to convict the pair on the principal charge. They hope to get both sentenced to a year in prison on a lesser charge. The payoffs are shown in Tab 2.

For monopolistically competitive firms, their products is important because many consumers do not like taking risks, and this way they can learn about products before buying them.

Monopolistically competitive markets:
combine characteristics of competitive markets and pure monopolies.
Deadweight loss represents the amount of surplus and surplus forgone because the monopolistically competitive firm charges a price higher than the marginal cost.

Because competitive firms have some control over prices, the firms will charge consumers the price they are willing and able to pay for the available output, which is found by projecting the profit-maximizing output level onto the curve.
