We explore the effects of uncertainty on a firm that can respond by modifying its investment or production schedule (or both simultaneously) to variations in output price. Investment may increase capacity and/or reduce costs. We consider a firm with finite resources.Our model uses option theory instead of the more traditional net present value framework. One of the early papers using this approach is Brennan and Schwartz (1985) in which an investment project to extract a finite natural resource is valued. In that paper, the value of the firm is a function of two state variables, the finite resource to be extracted (output to be produced in the future) and the commodity spot price. In order to maximize firm value, the manager can respond by modifying one control variable, the production level. In our model we handle instead three state variables (spot price, resources, accumulated investment) and two control variables (production rate and investment rate), and solve numerically.We obtain both the value and the optimal policy of a firm that has investment projects that increase capacity and/or reduce costs and illustrate optimal policies as resources and available investments decrease over the life of the firm. Firms may start by only investing, then invest and produce, to end only producing.We thank Scott Wo, the referee and the editor for their comments and suggestions.

Scholars have long debated whether leader's integrity affects managerial decision making with respect to social responsibility. In this paper, we propose a model in which transformational leadership mediates integrity and corporate social responsibility (CSR) and examine the relationship between these concepts. A survey of 170 senior managers from 50 organizations was conducted. Results indicate that integrity is a predictor of transformational leadership behavior and that transformational leaders’ behaviors are linked to CSR practices. It was also found that leaders rated with higher integrity are engaged in CSR because they exhibit more transformational leadership behaviors. These findings add to the extant literature by demonstrating that integrity is important as transformational leaders engage more actively on ‘responsible’ behaviors. Practical implications call for an understanding among corporate leaders of the benefits of integrity and how it relates to transformational leadership. Organizations can improve their selection and leadership development processes by focusing on these two dimensions.  相似文献

Fiscal harmonization among the European Union member states is a goal involving major difficulties for its implementation. Each country faces a particular trade-off between fiscal revenues generated by taxation and the productive efficiency loss induced by their respective tax code. This paper provides a quantitative analysis of these trade-offs for a number of the European Union (EU-15) member states using a dynamic general equilibrium model with public inputs. Calibration of the model for the EU-15 member states provides the following results: i) the maximum tax revenue level is relatively far from the current tax levels for most countries; ii) the cases of Sweden, Denmark and Finland are anomalous, as productive efficiency can be gained by lowering tax rates without affecting fiscal revenues; iii) in general, countries would obtain efficiency gains without changing fiscal revenues by reducing the capital tax and increasing the labor tax; and iv) capital tax harmonization to the average capital tax rate can be done with quite small changes in both fiscal revenues and output for most countries.  相似文献

The Institute of Medicine (IOM) has pointed out that the existing pandemic mitigation models lack the dynamic decision support capability. In this paper, we present a simulation optimization model to generate dynamic strategies for distribution of limited mitigation resources, such as vaccines and antivirals, over a network of regional outbreaks. The model has the capability to redistribute the resources remaining from previous allocations in response to changes in the pandemic progress. The model strives to minimize the impact of ongoing outbreaks and the expected impact of potential outbreaks, considering measures of morbidity, mortality, and social distancing, translated into the societal and economic costs of lost productivity and medical services. The model is implemented on a simulated H5N1 outbreak involving four counties in the state of Florida, U.S. with over four million inhabitants. The performance of our strategy is compared to that of a myopic distribution strategy. Sensitivity analysis is performed to assess the impact of variability of some critical factors on policy performance. The methodology is intended to support public health policy on effective distribution of limited mitigation resources.  相似文献

Faced with the threat of climate change, there is a challenge to promote more environmentally friendly consumption patterns. This work seeks to unearth psychographic and socio‐demographic factors that could trigger environmentally motivated reductions in consumption. The context of empirical investigation is the European Union (i.e., a large‐scale sample of European citizens), with a focus on two key types of environmentally motivated consumption reduction: domestic and “out‐of‐home” (purchasing) activities. The findings show the interrelated effects of environmental knowledge and ecological motivations (in both aggregated and disaggregated forms) on positive and negative environmental attitudes, which in turn influence consumption reduction. There is also evidence of significant moderating influences of perceived environmental threat, gender, age, education, and country value orientation—particularly on “environmental knowledge” links. The findings reported here contribute to theory and practice toward environmental sustainability.  相似文献

The relationship between social and financial performance (CSP – FP) has been a main objective in the literature on business management, as it would provide an economic justification for the social investment insofar as it contributes to the creation of value. This relationship has been empirically tested by several authors though without using a theoretical model that sustains this relationship. The aim of this article is to propose a theoretical model of the process of the creation of value from the reputation generated by companies, integrating the factors that have been shown to be more relevant in this process from previous research, in such a way that hypotheses are put forward regarding the existence of this relationship and the factors that determine it. Finally, an empirical test is performed using the 100 most prestigious companies operating in Spain during 2004.  相似文献

In order to identify discontinuous technological change and develop appropriate action, companies are increasingly building technology foresight (TF) practices. This paper explores how, using networks of experts, TF capabilities can be built. On the basis of three case studies and 43 interviews, it is shown that building foresight systems through networks of scouts yields several benefits, including the support for sourcing external technologies. Using insights from the three major telecommunication incumbents in Europe, the paper describes and discusses (1) what can be achieved by technology scouting, (2) how a process can be set up, (3) what is important in the design of a scouting network, and (4) the characteristics that should be aimed for when choosing technology scouts. The paper contributes to the methodological base of corporate foresight, to the technology management literature, and to the understanding of how companies can increase their open‐innovation capabilities by extending the intertwinement with their environment.  相似文献
