This paper carries out a systematic literature review of gameplay requirements by identifying gameplay aspects of Massively Multiplier Online games from publications released between 2004 and 2014. These aspects can be categorized to determine the state of the art regarding MMO’s. Aspects include MMO’s in general, their gameplay requirements, gameplay and player modelling, emergent gameplay, th...

Telecommunications industry is a highly competitive one where operators’ strategies usually rely on significantly reducing minute rate in order to acquire more subscribers and thus have higher market share. However, in the last few years, the numbers of customers are noticeably increasing leading to more stress on the network, and higher congestion rate, i.e. worse quality of service (QoS). Bec...

Water rates are designed to meet multiple objectives, typically resulting in tradeoffs among the objectives of economic efficiency, revenue sufficiency, and related revenue stability. Standard theory of natural monopoly is extended here to explain why long-run marginal cost (LMC) can be greater than both average cost and short-run marginal cost (SMC) for municipal water utilities. The distincti...

This paper determines the effect of voluntary contributions on the output and quality of nonprofit performing arts organizations, specifically classical ballet companies. The effect of ticket revenue on ballet companies is also estimated. The study uses newly presented data consisting of firm’s reported income, divided by source, and weekly wages of ballet dancers obtained from collective barga...

An economic driven JRRM algorithm is introduced in a multicell scenario based on guaranteeing a certain user acceptance probability of a given service while at the same time increasing the network provider revenue. It includes both service price and user utility and allows an operator to envisage the price impact on the final revenue attained. The paper focuses on two profiles, namely consumer ...

In this paper, we present a scalable pricing model for dynamic bandwidth allocation combined with simulation scenarios that demonstrate different aspects of a scalable service delivery model and at the same time guarantees a good level of resource utilization. The model allows for increasing the revenue while maintaining an acceptable level of quality of service (QoS) for users. Simulation resu...

The aim of this paper is to describe the state-of-the-art in simulation and to illustrate benefits and problems of linking micro and macro models by analysing flat tax proposals for Germany. The analysis shows that a personal income flat tax can indeed overcome the fundamental equity efficiency trade-off while simultaneously increasing the tax revenue. However, this result does not hold for a f...

An agronomic crop growth model—the Decision Support System for Agro-Technology Transfer—and a constant relative risk aversion utility function are used to examine corn irrigation strategies in Mitchell County, Georgia. Precipitation contracts are designed to help farmers manage risk. Three conclusions originate from the findings. First, the optimal irrigation strategy can greatly increase produ...

The generalized failure rate of a continuous random variable has demonstrable importance in operations management. If the valuation distribution of a product has an increasing generalized failure rate (that is, the distribution is IGFR), then the associated revenue function is unimodal, and when the generalized failure rate is strictly increasing, the global maximum is uniquely specified. The a...

The VCG mechanism is the gold standard for combinatorial auctions (CAs), and it maximizes social welfare. In contrast, the revenue-maximizing (aka optimal) CA is unknown, and designing one is NP-hard. Therefore, research on optimal CAs has progressed into special settings. Notably, Levin [1997] derived the optimal CA for complements when each agent’s private type is one-dimensional. (This does ...
