The objective of this study is to examine whether analysts fully incorporate a nonproportionate algorithm of cost-change relative to revenue-change in forecasting earnings. We conjecture that the errors in analysts’ earnings forecasts made in the first month after the fiscal year-end are largely due to the errors in estimating expenses as a result of analysts’ use of a proportionate cost-change...

We develop a two-sided market model that captures two unique features of the in-app mobile advertising market: the joint structure of the adverting platform and agency pricing for the app sales channel. In the joint structure of the mobile advertising platform, both the platform owner and the app developer jointly control the provisioning of ads compared to the platform owner alone in the tradi...

in today's competitiveenvironment, customers are the most important asset to any company. therefore,in order to retain customers, it is essential to understandtheirbehaviour for developing effective strategies. one of the most commonmethods for customer analysis is market segmentation that helps companies todevelop marketing technique by dividing market into several smaller homogeneousgrou...

We analyze a model where budget-constrained buyers need to partition their budgets among multiple capacity-constrained sellers. Each seller designs his allocation rule endogenously, as part of a two-stage game: First, sellers simultaneously design allocation rules. Second, given these rules, buyers simultaneously decide how to partition their budgets among the different sellers. The goal of eac...

This paper studies a supply chain coordinated by a revenue-sharing contract in fuzzy environment. Two kinds of fuzzy programming models are discussed: revenue-sharing contract with fuzzy linear demand model and fuzzy iso-price-elastic demand model. Supply chain coordination in both centralized decision setting and centralized decision setting are achieved by obtaining the optimal solutions in t...

The supply chain coordinating role of revenue-sharing has, to date, been examined only in static models. With downstream competition, the central conclusion in these models is negative: revenue-sharing cannot, except in degenerate form, achieve coordination. Incorporating dynamics, by allowing inventory carryover in discrete time, this paper establishes a foundation for revenue-sharing contract...

We study how interactions between financing and investment decisions can shape firm boundaries in innovative markets. In particular, we model innovative projects as growth options and ask whether they are best operated inside large incumbent firms (Integration) or in separate, specialized firms (Non-Integration). Starting from a standard theoretical framework, in which value-maximizing corporat...

The parametric cost estimation approach has proved to be an efficient method for analyzing complex systems such as spacecraft, missiles, ships, buildings, etc where cost varies according to a number of parameters. The cost to provision a telecom network also depends on a number of parameters; but little research effort has been applied to estimate cost using this approach. In estimating the cos...

In this paper we survey a number of different social software websites and analyze their revenue models. The main revenue models that we analyzed included advertising, premium memberships, affiliate programs, donations and merchandize sale. The survey will categorize different social software based upon the revenue model being adopted. The main aim of this paper is to highlight the need for stu...
