Change by Design     
Over the course of a century of professional practice, designers have mastered a set of skills that can be productively applied to a wider range of problems than has commonly been supposed. These include complex social problems, issues of organizational management, and strategic innovation. Conversely, non‐designers—those in leadership positions in companies, governmental and non‐governmental organizations, professionals in a broad range of services and industries—can benefit from learning how to think like designers. We offer some large‐scale and more finely grained ideas about how this might happen.  相似文献

In this paper, we study the costs and benefits of the adoption of a policy of free movement of workers. For countries to agree on uncontrolled movements of workers, short‐run costs must be outweighed by the long‐term benefits of better labor‐market flexibility and income smoothing. We show that such a policy is less likely to be adopted when workers are more impatient and less risk‐averse, when production technologies display stronger decreasing returns, and when countries trade a significant share of their products.  相似文献

The growing community concern for the environment, and rising energy costs to consumers, has led many power utility companies to adopt strategies aimed at reducing energy consumption in the home and workplace. These strategies have typically been based on extrinsically regulated pricing mechanisms. Although more intrinsically driven interventions have been examined, they are often complex and expensive to implement due in part to the high level of human interaction involved. This two‐part study suggests simpler more cost‐efficient alternatives to enhancing energy saving. It does this via two separate but related studies that examined the application of self‐determination theory (SDT) and word of mouth (WOM) within online communities. The findings suggest a significant increase in reported energy‐saving behaviors over time supporting the role of SDT. There was also evidence that positive WOM increases satisfaction of the three psychological needs of autonomy, competence, and relatedness, further enhancing energy‐saving behavior. These findings have important implications for marketers in terms of behavior change.  相似文献

We provide a new framework for estimating the systematic and idiosyncratic jump tail risks in financial asset prices. Our estimates are based on in-fill asymptotics for directly identifying the jumps, together with Extreme Value Theory (EVT) approximations and methods-of-moments for assessing the tail decay parameters and tail dependencies. On implementing the procedures with a panel of intraday prices for a large cross-section of individual stocks and the S&P 500 market portfolio, we find that the distributions of the systematic and idiosyncratic jumps are both generally heavy-tailed and close to symmetric, and show how the jump tail dependencies deduced from the high-frequency data together with the day-to-day variation in the diffusive volatility account for the “extreme” joint dependencies observed at the daily level.  相似文献

Since the seminal contribution of Jackson and Wolinsky (J Econ Theory 71(1):44–74, 1996) it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic behavior and collective outcome. What has not been studied systematically are the sources of inefficiency. We approach this omission by analyzing the role of positive and negative externalities of link formation. This yields general results that relate situations of positive externalities with stable networks that cannot be “too dense” in a well-defined sense, while situations with negative externalities tend to induce “too dense” networks. Those results are neither restricted to specific assumptions on the agents’ preferences (e.g. homogeneity), nor to a specific notion of stability or efficiency.  相似文献

Sweeney (2003) has stated that Anselm of Canterbury produced a paradoxical understanding: God is both inaccessible and obvious (p. 17). The current article proceeds analogically from Anselm's works to a consideration of whether Leadership Studies and the Social Sciences in general can access the obvious omnipresence of History. Finding that neither Leadership Studies nor the other Social Sciences can access that which is obvious, it then extends, in an Anselmian paradox, to discuss the inevitable use of History in Leadership Studies.  相似文献

Disclosure and the cost of equity in international cross-listing   总被引:1,自引:1,他引:0  
In this paper, we examine the relationship between disclosure level and the cost of equity capital for a sample of international firms cross-listing on the New York Stock Exchange. Increased disclosure has the potential to reduce information asymmetry, reduce the cost of financing and increase analyst following. Using an international asset pricing model, we find that listing firms experience a decrease in both disclosure risk and systematic risk while matching firms do not. Further, we find that the magnitude of the decrease is related to three types of disclosure: accounting standards; analyst following; and exchange/regulatory investor protection. Our results suggest that increased disclosure through accounting standards is beneficial to investors and that disclosure can be accomplished through information intermediaries, e.g., analyst following. For firms with the lowest levels of disclosure prior to cross-listing, all three types of disclosure appear to be valuable.

Current guidance in the UK and elsewhere indicate upper and target risk limits for the operation of nuclear plant in terms of individual risk per annum. ‘As low as reasonably practicable’ (ALARP) arguments are used to justify the acceptance or rejection of policies that lead to risk changes between these limits. The suitability of cost‐benefit analysis (CBA) and multiattribute utility theory (MAUT) are assessed for performing ALARP (‘as low as reasonably possible’) assessments, in particular within the nuclear industry. Four problems stand out in current CBA applications to ALARP, concerning the determination of prices of safety gains or detriments, the valuation of group and individual risk, calculations using ‘disproportionality’, and the use of discounting to trade‐off risks through time. This last point has received less attention in the past but is important because of the growing interest in risk‐informed regulation in which policies extend over several timeframes and distribute the risk unevenly over these, or in policies that lead to a nonuniform risk within a single timeframe (such as maintenance policies). The problems associated with giving quantitative support to such decisions are discussed. It is argued that multiattribute utility methods (MAUT) provide an alternative methodology to CBA which enable the four problems described above to be addressed in a more satisfactory way. Through sensitivity analysis MAUT can address the perceptions of all stakeholder groups, facilitating constructive discussion and elucidating the key points of disagreement. It is also argued that by being explicitly subjective it provides an open, auditable and clear analysis in contrast to the illusory objectivity of CBA. CBA seeks to justify a decision by using a common basis for weights (prices), while MAUT recognizes that different parties may want to give different valuations. It then allows the analyst to explore the ways in which different parties might (or might not) come to the same conclusion even when weighting items differently.  相似文献
