We provide sufficient conditions for the first-order approach in the principal-agent problem when the agent’s utility has the nonseparable form u(y−c(a)) where y is the contractual payoff and c(a) is the money cost of effort. We first consider a decision-maker facing prospects which cost c(a) and with distributions of returns y that depend on a. The decision problem is shown to be concave if the primitive of the cdf of returns is jointly convex in a and y, a condition we call Concavity of the Cumulative Quantile (CCQ) and which is satisfied by many common distributions. Next we apply CCQ to the distribution of outcomes (or their likelihood-ratio transforms) in the principal-agent problem and derive restrictions on the utility function that validate the first-order approach. We also discuss another condition, log-convexity of the distribution, and show that it allows binding limited liability constraints, which CCQ does not. 相似文献

While Collaborative Planning, Forecasting, and Replenishment (CPFR) information systems have been increasingly deployed to improve supply chain operations in a cross section of industries, the extant literature has largely overlooked the learning effects within organizations, thereby resulting in incomplete assessment of their business value. Using an operational-level panel data for nine product lines over 2.5 years, we empirically examine the learning curves in CPFR between Motorola, a mobile phone manufacturer, and one of its U.S.-based national retail partners. We found that the two key components of CPFR, collaborative forecasting (CF) and collaborative replenishment (CR), exhibit distinct learning curves. Forecast accuracy improves immediately following CPFR implementation but the rate of improvement slows over time, whereas inventory levels increase at first and begin decreasing after a period. Further, we found different learning effects in terms of inventory levels when products are later replaced with new form factors. Product replacements have lower inventory levels than their antecedents, at least for low-end products. We discuss important implications for theory and practice at the interface of information systems and operations management. 相似文献

In contemporary business environments, the ability to manage operational knowledge is an important predictor of organizational competitiveness. Organizations invest large sums in various types of information technologies (ITs) to manage operational knowledge. Because of their superior storage, processing and communication capabilities, ITs offer technical platforms to build knowledge management (KM) capabilities. However, merely acquiring ITs are not sufficient, and organizations must structure information system (IS) designs to leverage ITs for building KM capabilities. We study how technical and strategic IS designs enhance operational absorptive capacity (OAC) – the KM capability of an operations management (OM) department. Specifically, we use a capabilities perspective of absorptive capacity to examine potential absorptive capacity (POAC) and realized absorptive capacity (ROAC) capabilities – the two OAC capabilities that create and utilize knowledge, respectively. Our theory proposes that integrated IS capability, – an aspect of technical IS design – is an antecedent of POAC and ROAC capabilities, and business-IT alignment – an aspect of strategic IS design – moderates the relationship between integrated IS capability and ROAC capability. Combining data gleaned from a multi-respondent survey with archival data from COMPUSTAT, we test our hypotheses using a dataset from 153 manufacturing organizations. By proposing that IS design enables an OM department's KM processes, i.e., the POAC and ROAC capabilities, our interdisciplinary theoretical framework opens the “black box” of OAC and contributes to improved understanding of IS and OM synergies. We offer a detailed discussion of our contributions to the literature at the IS-OM interface and implications for practitioners. 相似文献

The EU Directive on informing and consulting employees (I&C Directive) is now established on the employment relations agenda with the provisions coming into force in the UK in April 2005. The I&C Directive potentially has far reaching consequences for the way UK employers inform and consult employees over a wide range of organizational issues, with the potential to transform the UK industrial relations environment. The initiatives contained in the I&C Directive and the subsequent introduction of the Information and Consultation of Employees (ICE) Regulations will take place in an employment relations environment in a period of significant change. Pressures of globalization have intensified competition in product and labour markets, emphasizing the need for greater efficiency and productivity. This has led to a greater focus on the link between employee participation practices and business strategy and organizational performance in search of an elusive (or illusory) fit? This paper is a commentary on the origins and rationale of this new legislation in the UK context, drawing on existing knowledge and academic debates in the area. In addition, the paper discusses the potential implications of the I&C Directive and the likely impact of the ICE Regulations on UK representative voice arrangements. 相似文献

Most research on employee involvement (EI) has focused on large or ‘mainstream’ organizations. By adopting those schemes which ‘appear’ to work well in larger organizations, smaller firms assume there will be enhanced employee commitment beyond formal contractual requirements. The main question in this paper is whether EI schemes designed by management will suffice under the 2004 Information and Consultation of Employees (ICE) Regulations. The paper focuses on SMEs which tend to favour informal and direct EI, and it remains unclear how these methods will be played out under the new regulatory environment. Evidence from four case studies is presented here and it suggests that the ICE Regulations impose new challenges for smaller firms given their tendency to provide information rather than consult with employees. It also appears organizational factors, workplace relations history and the way processes are implemented at enterprise level may be far more important than size itself. 相似文献

Recent theories based on sequential financing and information signaling reveal a special role for warrants. Data from initial public offerings (IPOs) of stock-warrant units have been used to test the theories, and we extend the analysis to seasoned offerings. Consistent with predictions from both families of theories, we find that issues made by smaller and younger firms are more likely to involve stock-warrant units, and firms with greater stock price volatility are more likely to issue units in seasoned offerings. Moreover, firms with relatively high levels of long-term debt, and those whose issues are underwritten by less prestigious underwriters are more likely to employ stock-warrant unit financing. Consistent with information signaling, we find that firms with high managerial ownership are more likely to issue units. Firms that include warrants in their stock offerings are predicted to have experienced higher abnormal stock returns than if they had issued shares alone. Thus, consistent with both theoretical explanations, some firms can reduce capital costs by adding warrants to shares in seasoned offerings. 相似文献
