Open innovation has received substantial business attention as a means of providing firms in hyper-competitive environments with the ability to create a stream of new products and services. For open innovation, organizing external sources correctly is a critical capability; current literature suggests that external sources should be organized either as collaborative communities or as competitive markets. While firms have generally been slow to adopt open innovation, many cities in the U.S. and Europe have been quick to embrace it—providing needed field-based experience on how to organize external sources. Based on our examination of six cities opening their data for innovation, we found that while cities often started with one or the other approach to organizing their external sources, each approach was inadequate in ways that could potentially be addressed by the addition of the other approach. Thus, we conclude with an integrated approach in which the needs of the entire ecosystem of sources and supporters of innovation are organized to address both competitive and community needs.  相似文献

The rapid growth of the Paraguayan economy over the last decade is analyzed in terms of the expansion of agricultural production and an increase in construction activity. Construction of the Itaipu Dam, the world's largest hydroelectric project, has provided employment and spurred private construction. A government colonization programme and spontaneous Brazilian immigration has brought new land into production. Favourable international prices for Paraguayan exports and funds from the Itaipu project swelled foreign reserves and served to maintain the Paraguayan currency at an already overvalued rate. The paper argues that the overvaluation, combined with extensive smuggling, undermined incentives for investment in manufacturing and deprived the government of revenues needed to finance infrastructure for sustained economic growth and development.  相似文献

Reactions of consumers to marketplace problems vary widely despite the frequent similarity of sources of dissatisfaction. The results of two studies designed to investigate the determinants of consumer inclinations to complain are presented. Two alternative social-psychological explanations of behavior employing self-monitoring, moral and social norms,and attitudes as predictor variables are examined.  相似文献

The accession of the UK to the European Community (EC) in 1973 occurred during a period of economic and political change that might have been expected to exert a profound effect on the agro-food sector. This article examines the extent of the recent developments in this sector and considers the influence of policy on those developments. Some conclusions are drawn with regard to future policy.  相似文献

Hypothetical bias is a common research problem in measuring intentions. This study examines differences in individuals' hypothetical and nonhypothetical willingness to pay (WTP) based on purchase intention level. The purpose of Study 1 is to see if hypothetical bias is affecting all groups of individuals when segmented by purchase intentions. The contingent valuation method (CVM) was used to assess to individuals' purchase intentions and hypothetical WTP for an environmentally friendly (EF) offering. Individuals then participated in an auction that required them to bid on the same offering, thus requiring an actual monetary commitment. Through segmenting individuals into three purchase intention groups (high, moderate, and low), WTP biases were found to be positively related to stated intention level. High and moderate purchase intenders significantly overstated their hypothetical WTP. However, low purchase intenders did not. Further, no significant differences existed in nonhypothetical WTP between the three groups. The price that low purchase intenders were willing to pay through the CVM represented closely what they and the rest of the market were willing to pay in practice. The purpose of Study 2 was to examine several reasons why higher purchase intenders may be overstating their hypothetical WTP, with normative pressure and social desirability bias taken into consideration. Individuals indicated their purchase intentions and hypothetical WTP for an EF and a non‐EF product, and then participated in an auction. The higher purchase intenders again overstated their actual WTP for both products, whereas low purchase intenders did not. Results suggest that both normative pressure and social desirability bias contribute to hypothetical bias for products that carry a normative dimension (EF products). Controlling for these two factors eliminated the differences between hypothetical and nonhypothetical WTP. For products that did not have a normative component (non‐EF products), controlling for social desirability eliminated the gap between the hypothetical and nonhypothetical WTP amounts. A main implication from this research is that hypothetical bias is not a universal phenomenon and does not operate equally in all groups of purchase intenders. Marketers may want to consider only using lower purchase intenders in their pricing estimates for new products, especially for those that carry a normative component. Further, the CVM has received much criticism for measuring hypothetical WTP. However, estimates produced by the CVM were nearly exact for the low purchase intender group and were reliable when controlling for social desirability bias and normative pressure for the higher purchase intenders.  相似文献

We conduct quantitative and qualitative analysis of 33 cases of internal and external whistleblowers wrongfully fired for reporting wrongdoing. Our results show external whistleblowers have less tenure with the organization, greater evidence of wrongdoing, and they tend to be more effective in changing organizational practices. External whistleblowers also experience more extensive retaliation than internal whistleblowers, and patterns of retaliation by management against the whistleblower vary depending on whether the whistleblower reports internally or externally. We discuss implications for organizations and whistleblowers, and we conclude that researchers need to develop different theoretical explanations of internal and external whistleblowing processes.  相似文献

Abstract

Aims: Among patients diagnosed with prostate cancer, 10–20% will develop castration-resistant prostate cancer (CRPC) within 5?years; for 70%, CRPC will metastasize, mostly to the lungs and/or liver. We performed a cost-effectiveness model comparing abiraterone plus prednisone (ABI?+?PRD), cabazitaxel plus prednisone (CAB?+?PRD) and enzalutamide (ENZ) for visceral metastatic CRPC post-docetaxel therapy resistance.

Methods: A three-state (Progression-Free, Progression, Death) lifetime Markov model was constructed to compare ABI?+?PRD, CAB?+?PRD, and ENZ from a United States healthcare payer perspective (2019?US$; discount rate 3%/yr.). Effectiveness was measured in life-years (LYs) and quality-adjusted life years (QALYs). Inputs included treatment costs, grade III/IV adverse events with incidence ≥5%, physician follow-up, lab and imaging tests. Phase III trial Kaplan-Meier curves were extrapolated to estimate overall survival and Progression-Free transition probabilities. Incremental cost-effectiveness ratios (ICERs) and utility ratios (ICURs), probabilistic sensitivity analyses (PSAs) and cost-effectiveness acceptability curves at willingness-to-pay (WTP) thresholds were estimated.

Results: Models estimated 3-year overall survival rates of 1.3% for patients treated with ABI?+?PRD, 16.2% for CAB?+?PRD, and 13.2% for ENZ. Estimated Progression-Free rates at 1.5?years were 0.51% for ABI?+?PRD, 0.27% for CAB?+?PRD, and 14.47% for ENZ. LYs and QALYs were 1.20 and 0.58 respectively for ABI?+?PRD, 1.48 and 0.56 for CAB?+?PRD, and 1.58 and 0.79 for ENZ. Total treatment costs were: $115,433 for ABI?+?PRD, $85,337 for CAB?+?PRD and $109,213 for ENZ. CAB?+?PRD and ENZ dominated ABI?+?PRD due to higher LYs gained. Incremental QALYs for ENZ vs. CAB?+?PRD were larger than incremental LYs. The ICUR for ENZ was $103,674/QALY compared to CAB?+?PRD.

Conclusions: This analysis found ENZ provided greater LYs and QALYs than both ABI?+?PRD and CAB?+?PRD, at a lower cost than ABI?+?PRD, but at a higher cost compared to CAB?+?PRD. For patients with visceral mCRPC after docetaxel therapy resistance, ENZ was cost-effective 92% of the time with a WTP threshold of $100,000/QALY.  相似文献

This article contributes to the literature on board effectiveness by being perhaps the first to systematically examine how the nature of outside directors' prior experience, and resulting expertise, will influence the performance of a focal firm's strategic initiatives. Our theoretical model is grounded in the psychological literature on expertise and its role in group decision making effectiveness. We focus on outside director expertise in acquisition decision making, and its implications for the performance of the acquisitions of a focal firm. Our conceptual framework indicates that directors will develop expertise in making particular kinds of acquisition decisions (e.g., related or unrelated acquisitions or acquisitions in specific industries or product markets) through their past experiences at other firms with decisions about those specific types of acquisitions, and we predict that this experience and expertise will have positive effects on the performance of a focal firm's acquisitions. We extend our theoretical model to consider the conditions under which relevant director experience will prove most beneficial. Our model predicts that outside director acquisition expertise will deliver the greatest benefits when the focal firm's board is independent from management. We find empirical support for all of our hypotheses. In considering how and when director experience and resulting expertise may influence the performance of corporate acquisitions, our theory and results help to highlight a potential second main focus for research on the long‐standing question of what factors render boards of directors effective.
