چکیده
We consider price and service-quality setting in oligopolistic markets for congestible services, applied to the case of private roads. Previous studies show that parallel competitors set a volume/capacity ratio (and thereby a travel time or service quality) that is socially optimal if they take the actions of the others as given. We find that this result does not hold when capacity and toll setting are separate stages—as then firms aim to limit toll competition by setting lower capacities, and thus higher travel times—or when firms set capacities sequentially, as then firms aim to limit their competitors’ capacities by setting higher capacities. In our Stackelberg competition, the last firm to act has no capacity decisions to influence. Hence, it is only concerned with the toll-competition substage, and sets a travel time that is longer than socially optimal. The first firm cares mostly about the competitors’ capacities that it can influence: it sets a travel time that is shorter than socially optimal. The average travel time will be too short from a societal point of view. JEL codes: D43; D62; L13; R41; R42

Is the Service Quality of Private Roads too Low, too High, or just Right when Firms compete Stackelberg in Capacity?
We study road supply by competing firms between a single origin and destination. In previous studies, firms simultaneously set their tolls and capacities while taking the actions of the others as given in a Nash fashion. Then, under some widely used technical assumptions, firms set a volume/capacity ratio that is socially optimal, and thus the level of travel time or service quality is socially...
متن کاملA Novel Method for Travel System Patterns
Due to population growth in urban areas, especially in the capital cities in developing countries, the use of private vehicles are increasing, leading to many problems such as congestion, pollution, noise, long travel time, high travel cost and more side effects. In such circumstances government policy would encourage people to use public transportation. In the meantime, employing the Intellige...

A man tried on a suit in a clothing store. Looking at himself in the mirror, the man observed that the jacket was too long in the back. “No problem,” said the salesman. “Just bend forward a little at the waist.” The man bent forward. The back of the suit now looked fine but he now saw that the left sleeve was a little too short and the right one a little too long. “No problem,” said the salesma...

Many patients do not interfere in medical practice. The reason for this behaviour naturalization is the wrong mentality that people are just sick of doctors. Knowing the right choice rather than as an omniscient doctor should follow. Too many patients are unaware of their right to decide. Look at this research stage diagnosis decision on recognition arrangements including t...
