This paper presents the results of a natural experiment conducted at a U.S. high‐tech manufacturer. The experiment had as its treatment the adoption, at a single point in time, of a comprehensive enterprise information system throughout the functional groups charged with customer order fulfillment. This information technology (it) adoption was not accompanied by substantial contemporaneous business process changes. Immediately after adoption, lead time and on‐time delivery performance suffered, causing a “performance dip” similar to those observed after the introduction of capital equipment onto shop floors. Lead times and on‐time delivery percentages then improved along a learning curve. After several months, performance in these areas improved significantly relative to preadoption levels. These observed performance patterns could not be well explained by rival causal factors such as order, production, and inventory volumes; head count; and new product introductions. Thus, this longitudinal research presents initial evidence of a causal link between IT adoption and subsequent improvement in operational performance measures, as well as evidence of the timescale over which these benefits appear.

In the mid-1990s, productivity growth accelerated sharply in the U.S. economy. In this paper, we identify several other industry-level changes that have occurred during the same time and argue that they are consistent with an increased use of information technology (IT). We use case studies to illustrate how IT has enabled firms to more rapidly replicate improved business processes throughout an organization, thereby not only increasing productivity but also market share and market value. We then empirically document a substantial increase in turbulence starting in the 1990s, as measured by the average intra-industry rank change in sales, earnings before interest, taxes, depreciation and amortization (EBITDA), and other metrics. In particular, we find that ITintensive industries account for most of this increase in turbulence, especially after 1995. In addition, we find that IT-intensive industries became more concentrated than non IT-intensive industries after 1995, reversing the previous trend. The combination of increased turbulence and concentration, especially among IT-intensive industries, is consistent with recent theories of hypercompetition as well as Schumpeterian creative destruction. We conclude that the improved ability of firms to replicate business innovations has changed the nature of business competition.

T his paper examines how firm investments in technology-based employee monitoring impact both misconduct and productivity. We use unique and detailed theft and sales data from 392 restaurant locations from five firms that adopt a theft monitoring information technology (IT) product. We use difference-in-differences models with staggered adoption dates to estimate the treatment effect of IT monitoring on theft and productivity. We find significant treatment effects in reduced theft and improved productivity that appear to be primarily driven by changed worker behavior rather than worker turnover. We examine four mechanisms that may drive this productivity result: economic and cognitive multitasking, fairness-based motivation, and perceived increases of general oversight. The observed productivity results represent substantial financial benefits to both firms and the legitimate tip-based earnings of workers. Our results suggest that employee misconduct is not solely a function of individual differences in ethics or morality, but can also be influenced by managerial policies that can benefit both firms and employees.

Electronic clinical data exchange promises substantial financial and societal benefits, but it is unclear whether and when it will become widespread. In early 2007 we surveyed 145 regional health information organizations (RHIOs), the U.S. entities working to establish data exchange. Nearly one in four was likely defunct. Only twenty efforts were of at least modest size and exchanging clinical data. Most early successes involved the exchange of test results. To support themselves, thirteen RHIOs received regular fees from participating organizations, and eight were heavily dependent on grants. Our findings raise concerns about the ability of the current approach to achieve widespread electronic clinical data exchange.
