Book Synopsis Essays on Firm Strategies and Consumer Dynamics in Socially Embedded Technology Networks by : Rajiv Mukherjee
Download or read book Essays on Firm Strategies and Consumer Dynamics in Socially Embedded Technology Networks written by Rajiv Mukherjee and published by . This book was released on 2013 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is of deep interest to researchers and practitioners in Information System (IS) to understand the efficacy of the traditional IS and economics theory in modern business environments such as online social networks. In the pursuit to understand such new IS phenomenon and address the gap in extant literature, my dissertation, identifies the strategies that the firms should incorporate in the presence of network effects; i.e., the increases in benefits accrued by a network user with an increase in the number of users, and its impact on consumer behavior. My first essay, challenges the traditional notion that network effects create a strong protective moat for the incumbent in network competition. I show that network effects are over rated in multi-homing setting, where users can co-exist across multiple networks under resource constraints. Over reliance on the strength of network effects by the incumbent firm in multi-homing setting, stems from extant economic theory that is applicable to single homing networks, where users has to choose one of the available networks. The first essay recommends strategies for the level of innovation and its time of delivery that firms should incorporate in order to survive and succeed in multi-homing environment. While the first essay focuses on multi-homing and the strength of network effects, the second essay revisits firm's preemption strategy in single homing setting with network effects, in order to prevent its users from migrating to a new entrant with better technology. I find that, for moderate levels of price and innovation competition, an incumbent with high reputation is better off being non-committal in its preemption. In contrast, committal preemption is apt for other combinations of reputation, innovation and price. While the first two essays focus on the impact of consumer behavior on firm strategies, the third essay delves into the impact of firm strategies on consumer behavior. In particular, I identify identity revelation policies that increase the number of successful transactions and collaborations in a socially embedded marketplace. The results imply that revealing social identities may be detrimental to negotiation and collaboration in a socially embedded marketplace -- a notion that is counter intuitive to networks that are inherently social.

Book excerpt: This dissertation consists of two projects, both concerned with how social networks form and how they affect economic decisions. In the first project, entitled Identifying Influential Agents in a Social Network, I define influence centrality, a new measure of influence which combines information on node and neighbor characteristics as well as information on the network structure, by building a model of friendship formation and peer effects and calculating the change in the equilibrium behavior of the network when one node changes its behavior. I apply the model to the context of smoking among middle and high school students and show that a targeted anti-smoking intervention in which a small number of influential smoking students are treated may be more efficient than a uniform program where every student in the school receives the same anti-smoking treatment. The second project, entitled Quantifying Spillovers in Network Formation Over Time, is a joint work with Sean Chu and Shankar Kalyanaraman at Facebook. The goal of the project is to separately identify and understand the relative importance of network effects and unobserved heterogeneity in a multi-period network formation model. Here, we define network effects to be the effect of the number of mutual friends on the probability of friendship and assume that unobserved heterogeneity is time-consistent. We estimate the model on a de-identified panel data set from a small group of users on Facebook and find that both network effects and unobserved heterogeneity are statistically and economically significant predictors of friendship formation on Facebook. We further re-estimate the model first, without network effects and next, without unobserved heterogeneity. Comparing the results from these specifications, we find that network effects play a more important role than unobserved heterogeneity in network formation models on Facebook.
Book Synopsis Essay on Network Effects, Consumer Demand, and Firms' Dynamic Pricing by : Rong Luo
Download or read book Essay on Network Effects, Consumer Demand, and Firms' Dynamic Pricing written by Rong Luo and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation includes three chapters on estimating structural economics models. My research focuses on empirically study consumers' utility from different products, the impact of network effects on consumers' demand for products, and multi-network firms' dynamic pricing strategies. The three chapters share the same feature of estimating a discrete choice demand model, but differ in the static versus dynamic setting and the underlying economics question and strategic behaviors that I'm interested.Chapter 1"The Operating System Network Effect and Telecom Carriers' Dynamic Pricing of Smartphones."The utility a consumer realizes from owning a smartphone increases with its operating system (OS) network size. Due to this OS network effect, multi-network telecom carriers have a different pricing strategy for smartphones than the single- network manufacturers in a dynamic environment. While manufacturers choose higher prices for larger networks, carriers, who can internalize competition across OSs, have incentives to choose lower prices for larger networks. The carriers' pricing strategy contributes to the increasing smartphone users and OS concentration. In this paper, I first analyze a theoretical model to compare the pricing strategies of the carriers and manufacturers. Then I design a structural model of consumers' demand and the carriers' dynamic pricing game for smartphones, and empirically study the impact of the OS network effect and carriers' two-year contract policy on the smartphone market penetration and OS concentration. I estimate the model using product level data from August 2011 to July 2013 in the US. I deal with the empirical challenges of dynamic prices for multi-product carriers, high dimension continuous state variables, and asymmetric oligopolistic firms in the estimation. The results show that the OS network size has a positive and significant impact on consumer utility. I then study two counterfactual cases in which I eliminate the OS network effect and the carriers' pricing strategy, respectively. I find that, without the OS network effect, the smartphone penetration rate would decrease by 54.7% and the largest OS share difference decrease by 31.7% by May 2013. Without the carriers' pricing strategy, the penetration rate would decrease by 29.1% and the OS market share difference decrease by 11.2%.Chapter 2"The Operating System Network Effect and Consumers' Dynamic Demand of Smartphones with Two-Year Contracts."This paper studies consumers' dynamic demand of smartphones on two-year wireless contracts. Individuals' demand decisions are affected by the improving quality and changing prices of smartphones, and the OS network effect, and their current smartphone contract status. Consumers need to pay high early termination fees if they end active contracts. The dynamic demand model in this paper incorporates the evolving choice set, prices, endogenous OS network sizes, and the termination policies in the smartphone industry. The preliminary results find that the OS network effect is large and significant. In addition, compared with dynamic model results, a static demand model tends to underestimate the OS network effect and overestimate price coefficient.Chapter 3"Store Brands and Retail Grocery Competition in Breakfast Cereals."This paper empirically analyzes the impacts of store brands on grocery retailers and consumers in the market for breakfast cereals. On the supply side, store brands help a retailer to avoid direct competition with other retailers and change the set of retailer's products. On the demand side, introducing store brands changes the national brands prices and consumers' choice set. We analyze the effects via demand estimation for a single grocery store chain Dominick's at Chicago in 1997 and counterfactual exercises. The estimation results show that consumers' unobserved utility of buying at a competing retailer is higher for consumers that value national brands, and is lower for ones that value Dominick's store brands. This is consistent with the claim that store brands help a retailer to avoid competition. The counterfactual calculations show that the profit loss from removing store brands is higher if the retailer has more competitors, with a median loss of 4.33% of profits from cereals. Existence of store brands increases national brands prices and consumer welfare increases slightly when store brands are removed.

Book Synopsis The Cold Start Problem by : Andrew Chen
Download or read book The Cold Start Problem written by Andrew Chen and published by HarperCollins. This book was released on 2021-12-07 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: A startup executive and investor draws on expertise developed at the premier venture capital firm Andreessen Horowitz and as an executive at Uber to address how tech’s most successful products have solved the dreaded "cold start problem”—by leveraging network effects to launch and scale toward billions of users. Although software has become easier to build, launching and scaling new products and services remains difficult. Startups face daunting challenges entering the technology ecosystem, including stiff competition, copycats, and ineffective marketing channels. Teams launching new products must consider the advantages of “the network effect,” where a product or service’s value increases as more users engage with it. Apple, Google, Microsoft, and other tech giants utilize network effects, and most tech products incorporate them, whether they’re messaging apps, workplace collaboration tools, or marketplaces. Network effects provide a path for fledgling products to break through, attracting new users through viral growth and word of mouth. Yet most entrepreneurs lack the vocabulary and context to describe them—much less understand the fundamental principles that drive the effect. What exactly are network effects? How do teams create and build them into their products? How do products compete in a market where every player has them? Andrew Chen draws on his experience and on interviews with the CEOs and founding teams of LinkedIn, Twitch, Zoom, Dropbox, Tinder, Uber, Airbnb, and Pinterest to offer unique insights in answering these questions. Chen also provides practical frameworks and principles that can be applied across products and industries. The Cold Start Problem reveals what makes winning networks thrive, why some startups fail to successfully scale, and, most crucially, why products that create and compete using the network effect are vitally important today.

Book excerpt: Brand extension allows a firm to leverage its current brand equity in its new product introduction. This study addresses three key issues in brand extensions: consumer affect transfer process, the impact of extension products on the parent brand equity and the stock market valuation of brand extensions. Essay 1 examines how brand affect is transferred from the parent product to the extension product. The congruency framework (expectancy and relevancy) is used to explain the affect transfer process. Results of three experimental studies suggest that both factors positively influence this process and the largest amount of affect is transferred when both conditions are met. Essay 2 addresses the network effects in brand extensions. The theory of network externalities from economics is used to explain the reciprocal network effects from the extension products to the umbrella brand. The study posits that three characteristics of the extension products' portfolio influence the parent brand equity: the portfolio size, the similarity among products in a portfolio and the presence of the attribute compatibility. Experimental findings firmly support these prescribed effects. Essay 3 assesses the stock market responses to the brand extension announcements and compares with two related strategies: line extension and brand alliances. The magnitude of the responses is the largest for brand alliances, moderate for brand extensions and the minimal for line extensions.
