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.

This paper examines the relationships amongst volatility, total trading volume (TVOL) and total open interest (TOI) for three Taiwan stock index futures markets as well as the role of the latter two variables in the dynamics of GARCH modeling and forecasting. From both ex-post and ex-ante perspectives, we study this issue by using the VAR model and augmented GARCH-type models, respectively. For the GARCH-type models, we employ both symmetric and asymmetric models augmented with lagged logs in TOI and/or TVOL. We find that whether addition of these two variables helps the basic GARCH models predict future volatility depends upon the sample period examined for all three sets of futures. Nonetheless, the best three models for out-of-sample volatility forecasting in the MSE sense are generally the augmented models for all sub-intervals and all three futures contracts.  相似文献

Even though electrical companies attain a top ranking in the publication of CSR reports, they are often accused of 'green‐washing' due to their bad environmental reputation. The current economic crisis is testing their real CSR commitment more than ever, especially when this goes beyond its economic consequences. Based on a worldwide sample of electrical companies, we are going to study why companies are being socially responsible. We wish to know if it is due to the impact on the firms' performance or whether there are other motives (legitimation, improving their reputation) that lead companies to carry out these practices. We will also consider if it changes across the kind of CSR action considered. The results show that there is an economic justification beyond the socially responsible behaviour of the electrical companies. Additionally, most kinds of CSR action (community, diversity, corporate governance, product responsibility) are also carried out looking for economic rewards. However, the CSR actions oriented to the environment are mainly motivated by their need to improve their image and reverse their negative impact.

This paper presents a gender perspective of the Trade Adjustment Assistance (TAA) program. The TAA is the primary US policy to assist the transition of workers displaced due to trade related economic restructuring. In comparison to the relatively substantial research on gendering trade policies in developing economies there is very limited focus on gendering policy responses to trade in the US. We argue that there is a specific gender trend in the trade-displacement patterns in the US which calls for a gender sensitive policy response. We examine the TAA in light of this trend and offer some suggestions for a gendered approach to providing assistance to workers negotiating an increasingly flexible global labor market.  相似文献

The British producer coop movement, though small, is of particular interest because of its rapid current growth and its unusual variety of organizational forms. In this paper, the history, institutional structure, recent development and economic performance of the sector are discussed and policy implications drawn. It is concluded that coops should be particularly aware of problems in management, finance and internal democracy. There remains considerable scope for further public intervention including the formation of specialized support agencies for activities like marketing and training, and to assist in the creation of new coops.  相似文献

This paper discusses the consequences of securitization and how it links to the Austrian Business Cycle Theory (ABCT). The argument that securitization is behind fiduciary credit expansion preceding the 2008 crisis is incomplete. Consolidated balance sheet analysis demonstrates that securitization per se actually sterilizes the inflationary effect of previous fiduciary credits by transforming them into credits backed by voluntary savings. This sterilization stage is subsequently followed by new fiduciary credits issuance as securitization creates excess reserves and excess capital for banks. However, when securitization is used as a tool to implement arbitrage strategies of the Basel prudential rules, it enables banks to create more fiduciary credit while time preference remains unchanged. This creates the conditions for business cycle amplification.  相似文献

Summary. In economies with public goods, we identify a necessary and sufficient condition for the existence of cost monotonic, Pareto optimal and individually rational mechanisms. These exist if and only if the preferences of the agents satisfy what we call the equal ordering property. We also show that when this condition holds the egalitarian equivalent correspondence is the only cost monotonic selection from the core of the economy. Furthermore, it is unambiguous in the sense that the agents are indifferent among all the allocations in it. Received: February 26, 1996; revised version: January 31, 1997  相似文献

Distance functions are gaining relevance as alternative representations of production technologies, with growing numbers of empirical applications being made in the productivity and efficiency field. Distance functions were initially defined on the input or output production possibility sets by Shephard (1953, 1970) and extended to a graph representation of the technology by Färe, Grosskopf and Lovell (1985) through their graph hyperbolic distance function. Since then, different techniques such as non parametric-DEA and parametric-SFA have been used to calculate these distance functions. However, in the latter case we know of no study in which the restriction to input or output orientation has been relaxed. What we propose is to overcome such restrictiveness on dimensionality by defining and estimating a parametric hyperbolic distance function which simultaneously allows for the maximum equiproportionate expansion of outputs and reduction of inputs. In particular, we introduce a translog hyperbolic specification that complies with the conventional properties that the hyperbolic distance function satisfies. Finally, to illustrate its applicability in efficiency analysis we implement it using a data set of Spanish savings banks.  相似文献

Perceptions of risks from two groups of industrial radiographers, one from Hungary, (n = 45) and from the United Kingdom, (n = 29) were compared by the psychometric method. The comparison was made because both groups were at risk for high doses of ionizing radiation. We found the groups had similar demographic profiles but poor socio-economic conditions of Hungarians were associated with higher levels of emotional distress. Correlation HU-UK for personal and general risks were at a significant level for topics that included lifestyle and radiation risks. Perceptions of risks from radiation were small except for large personal risk from East European nuclear power plants. Knowledge of radiation risk intranationally was correlated positively with personal risk for UK radiographers and negatively for Hungarians. However, average overall risk perceptions from the same topic list for all radiographers did not differ significantly from a group (n = 1461) of UK citizens, though radiographer's risks from radiation were considerably greater. As a new lifesaving intervention it was proposed that radiation risk reduction could be achieved by genetic testing.  相似文献

The asymmetric and persistent adjustment of the European real exchange rates is investigated using the framework of non-linear cointegration. The episodes of slow mean-reversion dynamics over the period from 1979 to 1999 are explained. A test of unit root against STAR cointegration is proposed and some complete estimations and stochastic simulations of ESTAR models are presented. The presence of effective non-linear adjustment during the moving of the currencies to their long-run fundamental equilibrium exchange rate value is discussed.  相似文献
