Suppose some firms exit an industry characterized by monopolistic competition. we would expect the demand curve of a firm already in the industry to
a. shift to the left.
b. shift to the right.
c. become less elastic.
d. remain the same since entering firms serve other customers in the market.

b. shift to the right.

Explanation:

A monopolistic competition is when there are many sellers of differentiated goods and services in an industry. Firms set the market price for their goods and services.

If firms leave the industry, the number of firms available to cater to consumers needs have reduced while the amount of consumers remain the same. Customers of the firms that exited the industry begin to patronize firms that are still in the industry. This leads to an increase in demand for existing firms and their demand curve shifts to the right.

I hope my answer helps you

cognitive overload: having a lot on your mind impairs decision-making and tends to result in the simplest, but not necessarily best, option being selected.

empathy gaps: overlooking how you might feel in a different situation can result in unnecessary purchases, such as overbuying when shopping for food on an empty stomach.

optimism and overconfidence: wearing rose-tinted glasses and having unrealistic expectations about the future can affect money management and leave you unprepared for a change in circumstance.

instant gratification: seeking instant gratification drives impulsive spending and can undermine long-term planning and savings.

harmful habits: automatic or mindless behaviour can amplify a poor financial decision as it becomes a recurring event.

social norms: we are heavily influenced by the actions of others; while this can be in certain circumstances, it also contributes to the pressure to keep up with the joneses through conspicuous consumption.
