  摘要：This study discusses a new procedure for masking confidential numerical data-a procedure called data shuffling-in which the values of the confidential variables are shuffled among observations. The shuffled data provides a high level of data utility and minimizes the risk of disclosure. From a practical perspective, data shuffling overcomes reservations about using perturbed or modified confidential data because it retains all the desirable properties of perturbation methods and performs bette...

  摘要：The year 2000 (Y2K) countdown provided a uniquely visible instance of spending on information technology (IT) by U.S. companies. With public attention riveted on potential Y2K malfunctions, managers were forced to evaluate their IT and make decisions about whether to modify or replace existing systems. In the aftermath of Y2K, critics charged that the problem was overblown and that companies overspent on IT. In contrast, we posit in this paper that efforts companies made to renew and upgrade t...
• Airlines as baseball players: Another approach for evaluating an equal-safety hypothesis AI翻译

  摘要：Within the First World, observed differences across air carriers in passenger death risk are almost never statistically significant. But given the rarity of fatal crashes, even a lopsided split of crashes across airlines is unlikely to achieve significance. For greater perspective about relative airline safety performance, we supplemented an analysis of overall mortality data with a two-part statistical procedure. The first part-which was inspired by the way the Oakland Athletics Major League ...
• Joint production and pricing decisions with setup costs and capacity constraints AI翻译

  摘要：We consider the problem of setting prices and choosing production quantities for a single product over a finite horizon for a capacity-constrained manufacturer facing price-sensitive demands. There is a fixed cost per production run and a variable cost per unit produced, both of which may vary by period. We characterize properties of the optimal solution, considering cases with constant and time-varying capacity, and with and without speculative motive for holding inventory. We show that, coun...
• Downside loss aversion and portfolio management AI翻译
  作者：Jarrow, R; Zhao, F

  摘要：Downside loss-averse preferences have seen a resurgence in the portfolio management literature. This is due to the increasing use of derivatives in managing equity portfolios and the increased use of quantitative techniques for bond portfolio management. We employ the lower partial moment as a risk measure for downside loss aversion and compare mean-variance (M-V) and mean-lower partial moment (M-LPM) optimal portfolios under nonnormal asset return distributions. When asset returns are nearly ...
• Location choices across the value chain:: How activity and capability influence collocation AI翻译
  作者：Alcacer, Juan
  作者单位：New York University
  摘要：There has been a recent revival of interest in the geographic component of firm strategy. Recent research suggests that two opposing forces-competition costs and agglomeration benefits-determine whether firms collocate in a given geographic market. Unexplored is (1) whether these forces have different impacts on R&D, production, and sales subsidiaries, leading to diverse collocation levels, and (2) how firm capabilities impact collocation by increasing or decreasing competition costs and agglo...
• Time value of commercial product returns AI翻译

  摘要：Manufacturers and their distributors must cope with an increased flow of returned products from their customers. The value of commercial product returns, which we define as products returned for any reason within 90 days of sale, now exceeds $100 billion annually in-the United States. Although the reverse supply chain of returned products represents a sizeable flow of potentially recoverable assets, only a relatively small fraction of the value is currently extracted by manufacturers; a large ...
• The architecture of participation: Does code architecture mitigate free riding in the open source development model? AI翻译
  作者：Baldwin, Carliss Y.; Clark, Kim B.
  作者单位：Harvard University; Brigham Young University
  摘要：This paper argues that the architecture of a codebase is a critical factor that lies at the heart of the open source development process. We define two observable properties of an architecture: (1) modularity and (2) option value. Developers can often make informed judgments about modularity and option value from early, partially implemented code releases. We show that codebases that are more modular or have more option value (1) increase developers' incentives to join and remain involved in a...
• Venture capitalists and cooperative start-up commercialization strategy AI翻译
  作者：Hsu, DH
  作者单位：University of Pennsylvania
  摘要：This paper examines the possible impact of venture capital (VC) backing on the commercialization direction of technology-based start-ups by asking: To what extent (if at all) do VC-funded start-ups engage in cooperative commercialization strategies (strategic alliances or technology licensing, or both) relative to a comparable set of start-ups, and with what consequences? To address these questions, I assemble a novel data set that matches firms receiving a federal research and development sub...
• Overoptimism and the performance of entrepreneurial firms AI翻译
  作者：Lowe, RA; Ziedonis, AA
  作者单位：Carnegie Mellon University; University of Michigan System; University of Michigan
  摘要：Recent theoretical and empirical research on cognitive bias in decision making suggests that overoptimism critically influences entrepreneurs' decisions to establish and sustain new ventures. We investigate whether such cognitive bias influences entrepreneurial venture performance using data on commercialization efforts for university inventions. In contrast to prior studies, our results suggest that entrepreneurial overoptimism does not appear to be the determining factor in the decision to f...
