Background* Maritime transportation is a crucial factor for economic growth. The shipping industry is structured through three main actors: - The Port Authority is generally a public entity that defines port practices and price regulation and can operate the terminal. Terminal operators manage terminal activities. - Shipping line companies move freight from origin to destination. Due to the increase in maritime transportation, larger container ships have been invested in bigger vessels generating economies of scale and reducing carrier costs during the last decades. The Swedish port system comprises 52 port authorities. Generally, local governments own seaports, and consequently, port charges represent a source of revenues for the municipality. Thus, there is intense competition among nearly port authorities to attract more traffic. In terms of traffic, the Port of Gothenburg is the largest seaport in Sweden. It has an extensive land transport connection through railway infrastructure to reach almost all regions in Sweden. * For further information, check: "Presentation Assignment 1". Assignment Assuming that there is no concession contract between the port authority and terminal operators, both port authorities own and manage their container terminals. This case study concerns market structures, firm strategies and interaction, and pricing schemes. The assignment is divided in two parts to analyzes a competition situation between two shipping lines and two port authorities. Firstly, suppose that each shipping line needs to transport a container cargo to Sweden. The vessels have two alternatives to design their route: the Port of Gothenburg and the Port of Helsingborg, i.e., the two main ports located on Sweden's western coast. Clearly, the cost that each shipping line will incur depends on the route choice, i.e., different port authority fees and costs. Secondly, suppose that two port authorities (i.e., the Port of Gothenburg and the Port of Helsingborg) with different characteristics aim to attract more traffic to increase their revenues (through their port dues). The report is expected to explore and analyze the following two parts:Part A - Shipping Lines' Perspective 1. Considering the actors (i.e., two shipping lines and the port authorities) and the predetermined cost functions described below (i.e., transportation costs and port fees), and determine the equilibrium outcome (price, quantity, and profit) of the game. Let q for i = 1,2 denote the number of containers transported by shipping line i. Assume a standard inverse demand function for a container of the form P = 10 000 - (q1 + 92) he Port of Gothenburg, private operators through concession contracts manage port terminals. However, to simplify the study, we assume that the Port Authority in Gothenburg is operating their terminals. and a total transportation cost function, excluding fixed costs, of the form TC = 100q + (q )2 for i = 1,2, and t= low, high, representing low and high diseconomies of scale, i.e., dlow
