Control of production of durable goods with account of monopolistic leasing

In the framework of the Coase hypothesis (that the monopolist producing durable goods turns out to be under the conditions of competition), a dynamic model of the market of these goods is constructed, and the possible methods of returning monopolistic power (monopolistic leasing and reduction of durability of goods) proposed by Coase are considered. The formulated problem of maximization of the producer’s profit is an optimal control problem which has a solution in the class of impulse controls. In this work, properties of durable goods and of boundaries of the Coase hypothesis are considered.     

Interacting oligopolistic and oligopsonistic Cournot markets

This paper considers the model of several interacting Cournot markets. Some of them are final goods markets, while the others are resource markets. The markets interact by sharing the same set of economic agents (producers), so that the latter are oligopsonists on resource markets and simultaneously oligopolists on goods markets. Each producer strategically chooses its supply volumes on each goods market and its purchase volume of resources in accordance with technology and expected supply effects on prices. We prove that in the case of linear demand and supply functions the model of interacting Cournot markets is reduced to a potential game; hence, the Nash equilibrium problem is equivalent to a mathematical programming problem. We also discuss the advantages and special features of such a representation of interacting oligopolistic and oligopsonistic markets.     

Service-oriented manufacturing: a new product pattern and manufacturing paradigm

Service plays an increasingly important role in modern manufacturing: (a) Services and physical products are integrated into one product service system (PSS) to provide a comprehensive solution for customers; (b) The companies involved in offering PSS focus on specialized sectors, and provide producer services for one another. In this paper, the new product pattern together with the innovative manufacturing paradigm is called service-oriented manufacturing. The competitive advantage of a PSS can be originated from products or services, and the ownership of PSS’s may or may not be transferred from sellers to buyers during transactions. Various PSS’s were categorized into three classes. The characteristics of each type of PSS’s and the shift between them are discussed. Many companies, which provide producer services and manufacturing services to one another, form a service-based manufacturing network. The reasons why producer services act as intermediate goods among different companies and motivations for companies to outsource their business processes are analyzed economically. Many companies in different segments of the production-chain may have discrepant profitability. Technology strength and industry insight competences are adopted to explain the discrepant values added from various segments along the production chain. Service-oriented manufacturing is summarized from the perspectives of business model, industry insight and technology strength (BIT).     

Model Selection in an Information Economy: Choosing What to Learn

As online markets for the exchange of goods and services become more common, the study of markets composed, at least in part, of autonomous agents has taken on increasing importance. In contrast to traditional complete–information economic scenarios, agents that are operating in an electronic marketplace often do so under considerable uncertainty. In order to reduce their uncertainty, these agents must learn about the world around them. When an agent producer is engaged in a learning task in which data collection is costly, such as learning the preferences of a consumer population, it is faced with a classic decision problem: when to explore and when to exploit. If the agent has a limited number of chances to experiment, it must explicitly consider the cost of learning (in terms of foregone profit) against the value of the information acquired. Information goods add an additional dimension to this problem; due to their flexibility, they can be bundled and priced according to a number of different price schedules. An optimizing producer should consider the profit each price schedule can extract, as well as the difficulty of learning of this schedule. In this paper, we demonstrate the tradeoff between complexity and profitability for a number of common price schedules. We begin with a one–shot decision as to which schedule to learn. Schedules with moderate complexity are preferred in the short and medium term, as they are learned quickly, yet extract a significant fraction of the available profit. We then turn to the repeated version of this one–shot decision and show that moderate complexity schedules, in particular two–part tariff, perform well when the producer must adapt to nonstationarity in the consumer population. When a producer can dynamically change schedules as it learns, it can use an explicit decision–theoretic formulation to greedily select the schedule which appears to yield the greatest profit in the next period. By explicitly considering both the learnability and the profit extracted by different price schedules, a producer can extract more profit as it learns than if it naively chose models that are accurate once learned.
