Available in PDF, EPUB and Kindle. Book excerpt: The first chapter is to investigate the impact of a free on-line repository of research articles on the diffusion of their ideas measured by the citation counts. The key questions that this chapter answers are as following: 1) does a free on-line repository of research articles increase the diffusion of their scholarly ideas measured by their citations?; 2) who benefits from the free access? By using a dataset from the Social Science Research Network (SSRN), an open repository of research articles, and employing a natural experiment that allows the effect of free access separate from other confounding factors, this study identifies the causal effect of free access on the citation counts as well as shows a heterogeneous effect of free access on both supply and demand side. The second chapter is to study the correlation between CEO pay and information technology. The hypothesis is that IT increases "effective size" of the firm that a top manager controls and thus her marginal productivity. In turn, in an efficient market, the firms with a higher degree of information technology will reward their CEOs with a higher compensation. The third chapter is to examine whether firms that emphasize decision making based on data and business analytics ("data driven decision making" or DDD) show higher performance. Using detailed survey data on the business practices and information technology investments of 179 large publicly traded firms, this study finds that firms that adopt DDD have output and productivity that is 5-6% higher than what would be expected given their other investments and information technology usage. Furthermore, the relationship between DDD and performance also appears in other performance measures such as asset utilization, return on equity and market value. Using instrumental variables methods, this study finds evidence that the effect of DDD on the productivity do not appear to be due to reverse causality. These results provide some of the first large scale data on the direct connection between data-driven decision making and firm performance.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is motivated by a goal to explain frequently observed phenomena in IT outsourcing that are, on face of it, counter-intuitive. In a set of three related essays, we examine why clients transfer critical assets to vendors, even when such asset transfer increases the risk of being "held-up" by a vendor. Moreover, there is considerable heterogeneity in which parties own the assets. We develop an explanation that helps us understand the motivations for asset ownership. Finally, we examine why vendors develop monitoring mechanisms that they share with their clients reducing the likelihood of appropriating rents. In a two period model of asset transfer, we show that asset transfer and contract extension work together to enable clients to incentivize vendors make significant initial investments. Owning the IT assets ensures a vendor about a long-term relationship while significant initial investments enable the vendor to win the contract extension. Then in an economic model that examines whether a vendor or client should own the assets, we show that scenarios exist both where the client and vendor agree on the ownership structure and where they disagree. When investment in innovation enables new services and features, the client should retain ownership of the assets. When investment leads to cost savings, the vendor should own the assets. The parties disagree on asset ownership structure when the investment opportunities yield similar levels of benefits to both vendor and client. In this case neither party wants to own the assets. A firm may also invest to increase the level of verifiability of future investments and thus increase the opportunity to extract more rents from the other party. Finally in a monitoring-signaling model, we show that by committing to costly performance monitoring and convening verifiable signals on his private information to the client, a high capability vendor is able to separate his expected payoff from that of the free-riding low capability vendor. The dynamics of truth-revealing signaling with performance monitoring involves that the client credibly commits to a long-term relationship with the appropriate vendor with incentive contracts contingent on the verifiable signals from performance monitoring.

This book was released on 2009-08-29 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The five essays in this thesis look at how specific information technologies (such as Electronic Document Management, Semantic Web and RuleML) and IT in general can be used to automate and standardize data and processes, enable faster and more accurate information flow, and improve individual as well as firm performance. The first essay is an analytical review-type study that provides a comprehensive survey of research literature about different complementary organizational assets that when coupled with IT can lead to higher firm performance. The second essay presents the causal effects of digitizing work on information workers' time-use and performance at a large insurance firm. The third essay examines the IT productivity relationship using a large primary source firm-level dataset about IT investments that spans the 2003- 2005 period. The fourth essay explores what high-performing firms specifically do to gain the greatest benefits from their IT investments. The fifth essay shows a detailed, realistic e- business application scenario that exploits capabilities of new Semantic Web technologies.

Available in PDF, EPUB and Kindle. Book excerpt: With the rapid development of computing devices and the improved Internet access, our daily lives and business world have been dramatically reshaped. While technology allows companies to attain unprecedented efficiency gains, it also brings about fundamental changes to the competition environment. The goal of this dissertation is to improve our understanding of three major technological developments through the lens of applied economics, econometrics, and machine learning. The first chapter is on the mobile application (app) market. The mobile app market is a fast growing platform which offers consumers millions of applications for smartphones and tablets, but the astronomical number of apps creates a search and discovery problem. I propose an optimal matching for a new advertising strategy, “Cross Promotion (CP),” which allows app developers to locate valuable users while helps app users discover new apps. Distinct from the extant platform literature, which consists mostly of theoretical formulations of platforms, I develop a two-stage model using data from a random matching experiment to examine how users preferences are influenced by apps characteristics. I propose a matching scheme which significantly improves the effectiveness of the CP using the deferred acceptance algorithm. The second chapter is on the issue of cybersecurity. I propose a potential information disclosure policy to alleviate cybersecurity threats. With a large-scale randomized field experiment consisting of 7,919 organizations in the U.S., I show through a random forest-assisted heterogeneous treatment effect analysis that the combination of information notification and publicity significantly reduces large spammers outbound spam volume, which is an indicator of an organizations underlying security condition. The last chapter investigates social media platforms, which is on companies social media strategies under challenging situations. Through a theoretical model, the use of support vector machine, and an empirical analysis using a large Twitter data set, I show the existence of both a negative spillover and a customer encroachment effect after the airline industrys major product-harm crises. In addition, I show that non-focal companies appear to harness two distinct functions of social media–offensive and defensive marketing strategies–to alleviate the negative influence and exploit the unexpected benefit as a result of such incidents

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This dissertation investigates the relation between investment-specific technical change and long-run economic growth. The first essay points out the discrepancy between the steady state growth theorem and recent economic growth driven by information technology. Previous study finds that investment-specific technological progress accounts for 58% of economic growth in the U.S. However, their result hinges on the assumption of the Cobb-Douglas production function. This paper employs the CES production function to investigate the effect of investment-specific technological progress on long-run economic growth. In the steady state, quality improvement in each vintage is directed to expand more functions in one machine, resulting in contraction in the types of capital. The offsetting effect between quality and variety implies that the relative capital income share is constant in the steady state. Empirical tests for the U.S. data show that investment-specific technological progress does not generate long-run economic growth. The elasticity of substitution is significantly less than one, and that there is an offsetting effect to investment-specific technological progress. The second essay investigates the quality changes in capital and labor inputs across 46 industries from 1968 to 2001. We incorporate a time-varying quality measure to the efficiency units of capital. The result indicates that the average quality of capital assets over time has improved 46 percent in the cross industry average. The quality improvement effect accounts for 30 percent in the total growth of the efficiency units of capital. Although the net quantity effect is still the largest component in the growth of the efficiency units of capital, there is significant substitution among different vintages and asset types as well. The average quality growth in the efficiency units of labor is 17 percent. The third essay investigates unbalanced growth facts and their implications for existing growth theory. We find that the balanced growth implication is consistent with data for the United States at the national aggregate level, but not at a more disaggregate level and internationally. Among the various unbalanced growth facts, the increases in the depreciation rates of equipment and of aggregate capital have the most significant impact on the growth theory. Under the Cobb-Douglas framework, an increasing depreciation rate of equipment can result in rising, constant, or declining rate of return of equipment, depending on the magnitude of the decreasing net marginal product effect and the capital loss effect.

This book was released on 2012-12-06 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon chip technology; microprocessor technology; information technology; or quite simply new technology. These are some of the names representing the microelectronics revolution depending upon the audience being addressed by speaker or writer. No previous new industrial development has caused such widespread publicity and discussion amongst users and researchers as the new technology. Concern is being expressed about the effects of new technology on employment, job satisfaction, social life, leisure activities and the economics of commerce and industry. The late 70s saw many doom-laden predictions of those effects but by 1983 both management and trade unions were taking a more objective view of the social and economic impacts, and many correspondents now see the new technology as a means of opening up new industries and overcoming the effects of world recessions. The "chip" has involved the factory floor, the office, the supermarket and the home. Electronic funds transfer, electronic shopping, microelectronic domestic appliances, word processors and microprocessor-controlled machinery mean that the new technology has pervaded all aspects of social and economic life, and the developed countries are now coming to accept it as part of society as a whole. Inevitably the flood of literature on the social and economic impacts of new technology has been overwhelming. Unfortunately the quality of information and arguments propagated at conferences, in journal papers and research reports has indicated that there has been little quantifiable evidence available on the effects of these impacts.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. healthcare system is characterized as inefficient, with excessive expenditure but low care quality. Recent healthcare reform aims to address these concerns and advocates health information technology (IT) as a key component to assist in this goal. In this dissertation, we study the role of health IT innovations under the value-based care structure in reducing cost, boosting quality of care, and improving healthcare efficiency. In the first essay, we focus on the Medicare Accountable Care Organization (ACO) program, which is a major healthcare payment reform initiative. We find that electronic health record (EHR) as an enabler of health information exchange enhances the association between ACO efficiency and quality of care. Our results indicate that meaningful use of EHR contributes to the capability to pursue both performance dimensions with respect to delivery of high-quality care in an efficient manner. In the second essay, we further verify that health information sharing is beneficial in terms of shorter emergency department wait time, reduced inpatient expense, and lower length of stay. However, it is not easy to exchange patient health records across providers. We empirically show that hospitals that adopt electronic medical records (EMR) from commercial vendors are more likely to exchange clinical data when compared to hospitals that use self-developed EMR systems. We also find that both participating in a health information exchange (HIE) and using the same EMR as other regional peer hospitals contribute to the capability of communicating patient data. In the third essay, we focus on patient-centric health IT, termed “patient portals”. We examine the impact of effective usage of patient portal technologies on health outcomes of congestive heart failure patients. We observe that frequent usage of clinical-oriented features, including viewing lab results, requesting medication refills and advice, and interactive messaging with providers, is associated with improvements in several health outcome measures with respect to the frequency of inpatient and emergency visits, readmission risk, and length of hospital stay. Collectively, this dissertation reveals the impact and the mechanism through which health IT systems are improving healthcare delivery, thereby providing a foundation to better understand the role of health IT in the era of healthcare reform. We posit that our findings provide implications associated with the adoption and usage of health IT for healthcare practitioners and policy makers, in an endeavor to revive the U.S. healthcare system.
