We present a number of models for the adword auctions used for pricing advertising slots on search engines such as Google, Yahoo! etc. We begin with a general problem formulation which allows the privately known valuation per click to be a function of both the identity of the advertiser and the slot. We present a compact characterization of the set of all deterministic incentive compatible dire...

In the presence of network externalities, product features compatible with standards and larger installed bases of the relevant technologies lead to expanded market shares and increased customer valuation. Our research finds that firms which collaborate with other organizations do so to enhance product compatibility and expand their installed bases. We study the effects of such cooperative stra...

To progress toward universal health coverage and promote inclusive social and economic development, it will be necessary to strengthen domestic resource mobilization for health. In this paper, we examine options for increasing domestic government revenue in low- and middle-income countries. We analyze the relationship between level of economic development and levels of government revenue and ex...

We address the problem of designing efficient mechanisms that never yield revenue, instead requiring small subsidies. Such mechanisms will be pertinent for settings in which taxing agents is undesirable or impractical—imagine, e.g., a government or private philanthropist that seeks to make a minimal monetary contribution that will allow a group of individuals to reach an efficient decision with...

We study how interactions between financing and investment decisions can shape firm boundaries in dynamic product markets. In particular, we model a new product market opportunity as a growth option and ask whether it is best exploited by a large incumbent firm (Integration) or by a separate, specialized firm (Non-Integration). Starting from a standard theoretical framework, in which value-maxi...

When an innovative product is introduced into the market, consumers are often uncertain about the product value. Over time they may learn the value of product. This paper studies the impact of consumer learning on the firms' marketing efforts and revenue sharing strategies in a supply chain that sells an innovative product to consumers over multiple periods. Both the supplier and the retailer c...

This study examines the incentives for content contribution in social media. we propose that exposure and reputation are the major incentives for contributors. Besides, as more and more social media web sites offer advertising-revenue sharing with some of their contributors, shared revenue provides an extra incentive for contributors who have joined revenue-sharing programs. we develop a dynami...

This paper identifies the efficiency-oriented critical drivers for e-market using a two-stage approach. The efficiency of twenty-six e-markets is investigated first with respect to their respective overall efficiency, technical efficiency and scale efficiency, leading to the identification of the fully efficient emarkets and the underlying source of inefficiency in the existing e-markets. The e...

introduction: establishing improvement in every organization requires assessment of organizational performance, planning and goal-setting to improve the performance. despite remarkable progresses occurred in recent years on designing the frameworks and performance evaluation systems, many organizations still rely on traditional criteria. therefore, according to the importance of performance eva...
