We study interindustry information technology (IT) spillover wherein IT investments made by supplier industries increase the productivity of downstream industries. Using data from U.S. manufacturing industries, we find that industries receive significant IT spillover benefits in terms of total factor productivity growth through economic transactions with their respective supplier industries. More importantly, we find that two characteristics of downstream industries, namely, IT intensity and com

This paper examines the effects of IT-related spillovers on firm-level productivity improvements over a long-term horizon. In contrast, prior research has largely focused on the direct and contemporaneous impacts of IT investments. As a result, we do not fully understand how IT investments are associated with ongoing productivity improvements in future periods and how spillovers influence these gains. In this paper, we examine whether firms receive incremental benefits from IT-related spillovers

Information technology outsourcing (ITO) is the predominant mode of acquiring information systems services, providing clear evidence that the economics of service delivery favor external service providers over in-house information systems departments. An interesting feature of many large ITO arrangements is that the production assets necessary for service delivery are transferred to the vendor. The argument in favor of such asset transfers, based in property rights theory, is that they are neces

We analyze the impact of information technology (IT) on the technical efficiency of firms in the context of their observed competitive settings. Because competition can be a driver of efficiency and industries display varying degrees of competitiveness, firm-level efficiency is likely to display considerable heterogeneity. To shed light on these questions, we analyze the economic impact of IT on technical efficiency, a key component of efficiency, in heterogeneous competitive settings. Our study

We address the dynamics of post-merger risks for a firm acquiring an information technology (IT) company over a long-term horizon, and examine the impact of mergers and acquisitions (M&A) motives on its post-merger risks after controlling for its self-selection into the specific motives the acquiring firm seeks. We find that a strong run-up in risk occurs before M&A transactions are initiated, but this risk begins to decline over the post-merger period. However, post-merger risks tend to persist

The impact of information technology on productivity has been debated for two decades. While some studies in the1980s found no contribution of IT to output, more recent studies have found a positive return to IT investment in several industries. However, we have a limited understanding of industry differences in these returns, in particular as to why productivity enhancements in the trade and service sectors, which are IT- intensive, have been low. A few previous studies have reported the differ

전 세계적으로 기업의 중요한 전략적 수단으로 인수합병이 활발히 이루어지고 있고, 지능형 서비스 산업을 포함한 정보기술 산업에서의 인수합병 활동은 꾸준히 활발하게 진행되고 있다. 본 논문에서는 정보기술 산업 내에서 일어나는 인수합병 건에 대해 인수 기업 입장에서의 인수 의도에 초점을 두고 분석하였다. 특히, 두 하드웨어 기업 간, 하드웨어 기업 소프트웨어 기업 간, 두 소프트웨어 기업 간 인수합병 유형에 따라 인수 의도가 어떻게 다른지 비교하고자 하였고, 이를 위해 미국 정보기술 산업 내에서 1995년과 2010년 사이에 일어났던 1003개의 인수합병 건의 자료를 분석하였다. 인수 의도를 파악하는데 있어, 인수 기업의 입장에서 생산비용 절감 의도, 제품 개발 및 개선 의도, 고객층 확장 의도, 고객채널 확장 의도의 네 가지로 구분하여 측정하였다. 분석 결과 생산비용 절감 의도와 고객층 확장 의도는 하드웨어 기업이 피인수 기업일 때 더 많이 나타났고, 제품개발 의도는 하드웨어 기업이 인

As the Internet becomes ubiquitous, a large volume of information is posted on the Internet with exponential growth every day. Accordingly, it is not unusual that investors in stock markets gather and compile firm-specific or market-wide information through online searches. Importantly, it becomes easier for investors to acquire value-relevant information for their investment decision with the help of powerful search tools on the Internet. Our study examines whether or not the Internet helps inv

The omnipresence of software firms is triggering substantial antitrust concerns, calling into question the adequacy of existing regulatory frameworks. This study explores this pivotal concern in the context of the software industry, which is characterized by profound network externalities among customers and a rapid pace of innovation. Our study used the event study methodology on data from 252 antitrust cases involving the U.S. Federal Trade Commission and U.S. Department of Justice from 2000 t

This study aims to investigate the economic value of cloud computing from the perspective of the stock market. More specifically, we conceptualize the relationship between the cloud computing initiatives of firms and the market reaction based on resource-based and extended resource-based views. For this study, we analyze 212 firm-level cloud computing announcements between 2006 and 2011 by employing the event study methodology. Our empirical results indicate that the market positively reacts to
