This study focuses on polychronicity as a cultural dimension of top management teams (TMTs). TMT polychronicity is the extent to which team members mutually prefer and tend to engage in multiple tasks simultaneously or intermittently instead of one at a time and believe that this is the best way of doing things. We explore the impact of TMT polychronicity on strategic decision speed and comprehensiveness and, subsequently, its effect on new venture financial performance. Contrary to popular time‐management principles advocating task prioritization and focused sequential execution, we found that TMT polychronicity has a positive effect on firm performance in the context of dynamic unanalyzable environments. This effect is partially mediated by strategic decision speed and comprehensiveness. Our study contributes to research on strategic leadership by focusing on a novel value‐based characteristic of the TMT (polychronicity) and by untangling the decision‐making processes that relate TMT characteristics and firm performance. It also contributes to the attention‐based view of the firm by positioning polychronicity as a new type of attention structure. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Our paper aims to analyze the effectiveness of different risk-sharing mechanisms in providing stability to a monetary union. We select two stylized tools with extreme and opposite features. The first is an expansionary but conventional monetary policy that is used to help EMU’s most fragile member states manage their public debts; the second is a centralized fiscal policy that allows for the transfer of a portion of these public debts from EMU’s most fragile member states to those considered EMU’s “core”. By a stylized periphery-core model of a monetary union, we compare the strengths and weaknesses of these two tools in order to reach some welfare implications in terms of union stability. 相似文献

This paper investigates the empirical and theoretical basis of the decoupling between energy throughput and economic growth, with a critical view of the use of the decoupling concept as a policy priority. We provide an analysis of the historical trends of the metabolic pattern of European economies over a period of 18 years focusing on the changes in energy throughput and financial assets. The results show that energy consumption per hour of labor has remained constant, suggesting that no significant changes in production processes or technology have taken place in the productive sectors of the economy. The contribution of this paper is to establish a bridge between the economic analysis of financialization and the societal metabolism analysis of the economic process from a biophysical point of view. We argue that this bridge is crucial to draw attention to the biophysical consequences of financialization (a relative decoupling) and critically assess the pertinence of policies aimed at encouraging the decoupling in the context of increasing inequality. 相似文献

We show that multivariate Hawkes processes coupled with the nonparametric estimation procedure first proposed in Bacry and Muzy [IEEE Trans. Inform. Theory, 2016, 62, 2184–2202] can be successfully used to study complex interactions between the time of arrival of orders and their size observed in a limit order book market. We apply this methodology to high-frequency order book data of futures traded at EUREX. Specifically, we demonstrate how this approach is amenable not only to analyse interplay between different order types (market orders, limit orders, cancellations) but also to include other relevant quantities, such as the order size, into the analysis, showing also that simple models assuming the independence between volume and time are not suitable to describe the data. 相似文献

Knightian Uncertainty in Financial Markets: An Assessment 总被引:1,自引:0,他引:1
Marcello Basili 《Economic Notes》2001,30(1):1-26
If information is too vague and imprecise to be summarized by a unique additive probability measure, an agent faces Knightian uncertainty or ambiguity rather than risk. Under Knightian uncertainty, an agent's beliefs may be represented by a capacity or a set of additive probabilities. It is proved that an agent's attitude towards ambiguity has a crucial role in asset price determination and portfolio choice. Knightian uncertainty attitude provides an alternative explanation of financial market failures and enables puzzles to be solved, such as market breakdowns, price indeterminacy and volatility, bid and ask spreads, portfolio inertia, violation of call and put parity.

Competition in hospital care is often implemented through mixed markets where public and private hospitals compete for patients. The optimality of this market form has long been debated in the literature. In this paper, we investigate the role of soft budget constraint in affecting patient selection within a mixed market. Patient selection is the undesired effect of hospital competition when three conditions are met: asymmetry in hospitals’ objectives, presence of hospital’s private information and inability to enforce hard budget constraint. The paper shows that soft budget is a pre-condition for the existence of patient selection. Our paper adds an important dimension to the existing literature which considers asymmetry of information as the only cause for this market failure. The understanding of the mechanisms leading to patient selection makes it possible for the regulator to design measures to reduce such undesirable effect. 相似文献
