This paper studies the effect on company performance of appointing non-executive directors that are also executive directors in other firms. The analysis is based on a new panel dataset of UK companies over 2002–2008. Our findings suggest a positive relation between the presence of these non-executive directors and the accounting performance of the appointing companies. The effect is stronger if these directors are executive directors in firms that are performing well. We also find a positive effect when these non-executive directors are members of the audit committee. Overall, our results are broadly consistent with the view that non-executive directors that are executives in other firms contribute to both the monitoring and advisory functions of corporate boards. 相似文献

I develop a robust political economy of bureaucracy by highlighting the conditions necessary for hierarchical administrative bodies to govern protectively and productively, but not predatorily. These conditions are residual claimancy and jurisdictional competition. I make this argument by exploring a post‐cameralist interpretation of governance. Cameralism arose as a governance philosophy in the fractured principalities of seventeenth‐century Germany following the Thirty Years' War. Post‐cameralism focuses not on particular cameralist governance strategies but on a paradigm which sees governance as an activity provided within a larger exchange order, rather than imposing itself on that order as in more conventional treatments of public economics. While a post‐cameralist conception of governance comes with its own challenges, such as tensions with normative visions that promote self‐governance, it nonetheless presents an intriguing synthesis of monocentric and polycentric insights. 相似文献

Innovation portfolio management (IPM) is a dynamic decision‐making process, in which projects are evaluated and selected, and resources are allocated. Previous research has developed an understanding of IPM success and its influencing factors. However, little research investigated the quality of the decision‐making process and the ability to quickly adapt the portfolio. This study focuses on the antecedents of decision‐making quality and agility (i.e., responsiveness to changes in the environment). Based on a decision‐making framework, five structural and cultural IPM components are derived as important antecedents of decision‐making quality, which in turn influences agility. The structural components (1) clarity of strategic goals, (2) formality of the IPM processes, and (3) controlling intensity serve a coordinating function. The cultural components (4) innovation climate and (5) risk climate serve a motivating function in IPM. An analysis of a sample of 179 firms and their innovation portfolios through structural equation modeling using a double‐informant design documents that these five components all positively influence portfolio decision‐making quality, which in turn positively influences agility. Results further show that environmental turbulence moderates some of these relationships. While the positive effect of process formality is weakened under increasing turbulence, the effects of controlling intensity and climate for innovation are strengthened by environmental turbulence. The findings have theoretical implications for the understanding of IPM as a dynamic capability and practical implications for the management of portfolios in turbulent environments. 相似文献

We conduct a laboratory experiment with agents working on, and principals benefiting from, a real effort task in which the agents' performance can only be evaluated subjectively. Principals give subjective performance feedback to agents, and agents have an opportunity to sanction principals. In contrast to existing models of reciprocity, we find that agents tend to sanction whenever the feedback of principals is below their subjective self‐evaluations even if agents' pay‐offs are independent of it. In turn, principals provide more positive feedback (relative to their actual performance assessment of the agent) if this does not affect their pay‐off. 相似文献

Policy debates suggest a future role for geologic carbon sequestration. As geologic sequestration (GS) evolves from enhanced oil recovery operations to an emissions‐mitigation option, regulations must evolve to manage the risks of carbon dioxide (CO2) migration. We develop an engineering‐economic model to understand the key deployment pathways in this transition. Major results reveal that dedicated CO2 storage in aquifers is associated with the greatest net revenues under only a limited number of scenarios. This finding suggests that regulators should anticipate GS operations in reservoirs that were not initially intended as GS operations and, therefore, may have higher leakage rates.

This article presents an analysis of occupational structure, a key component of the ‘Little Divergence’, in an eastern‐central European economy under the second serfdom, using data on 6,983 Bohemian villages in 1654. Non‐agricultural activity was lower than in western Europe, but varied positively with village size, pastoral agriculture, sub‐peasant strata, Jews, freemen, female headship, and mills, and negatively with arable agriculture and towns. It showed a curvilinear relationship with the ‘second serfdom’, as proxied by landlord presence on village holdings. Landlord presence in serf villages also reversed the positive effects of female headship and mills on non‐agricultural activities. Under the second serfdom, landlords encouraged serf activities from which they could extract rents, while stifling others which threatened manorial interests. 相似文献

The deployment of battery-powered electric bus systems within the public transportation sector plays an important role in increasing energy efficiency and abating emissions. Rising attention is given to bus systems using fast charging technology. This concept requires a comprehensive infrastructure to equip bus routes with charging stations. The combination of charging infrastructure and bus batteries needs a reliable energy supply to maintain a stable bus operation even under demanding conditions. An efficient layout of the charging infrastructure and an appropriate dimensioning of battery capacity are crucial to minimize the total cost of ownership and to enable an energetically feasible bus operation. In this work, the central issue of jointly optimizing the charging infrastructure and battery capacity is described by a capacitated set covering problem. A mixed-integer linear optimization model is developed to determine the minimum number and location of required charging stations for a bus network as well as the adequate battery capacity for each bus line. The bus energy consumption for each route segment is determined based on individual route, bus type, traffic, and other information. Different scenarios are examined in order to assess the influence of charging power, climate, and changing operating conditions. The findings reveal significant differences in terms of required infrastructure. Moreover, the results highlight a trade-off between battery capacity and charging infrastructure under different operational and infrastructure conditions. This paper addresses upcoming challenges for transport authorities during the electrification process of the bus fleets and sharpens the focus on infrastructural issues related to the fast charging concept. 相似文献

Abstract We propose a simple, yet sufficiently encompassing, classification scheme of monetary economics. It comprises three fundamental fields and six recent areas that expand within and across these fields. The elements of our scheme are not found together and in their mutual relationships in earlier studies of the relevant literature; neither does this attempt aim to produce a relatively complete systematization. Our intention in taking stock is not finality or exhaustiveness. We rather suggest a viewpoint and a possible ordering of the accumulating knowledge. Our purpose is to promote discussion on the evolving nature and internal consistency of monetary economics at large. 相似文献
