It is shown that under incomplete information it may be optimal for a monopolist to ration a single price taker in addition to setting prices, which is in contrast to the case of complete information. As a byproduct it is shown that the star-shaped hull of the offer curve of a price taker exactly consists of the points that can be supported as Drèze-optima. 相似文献

In this note we sketch the main features of the dynamic evolution of a rationed equilibrium macroeconomic model in which prices and wages respond to excess demands and inflation expectations, and the money stock is endogenous. We postulate monetarist inflation expectations, i.e., expected inflation is assumed to be equal to the current percentage rate of change of the money stock. If the system is stable, monetarist inflation expectations are asymptotically rational. 相似文献

A simple model with two stages of production is used for deriving some empirically testable hypotheses. Firms (two upstream and two downstream) in the industry are either vertically integrated or not, hence the industry has three alternative patterns: Complete unintegrated, partially integrated, or fully integrated.Final good prices, outputs and profits of firms are different in each integration pattern but what is optimal can not be stated (i.e., pay-offs are much too complicated in order to solve the sub-game equilibrium).The essential feature of the model is that there are external markets for the intermediate inputs. Hence input trade between the four firms/divisions need not balance since excess supply or demand is traded at the external market. With this feature purely downstream exogenous shocks have no effect on upstream pricing nor production decisions if all four firms are unintegrated. Such exogenous shocks have non-zero effects if at least one firm is vertically integrated. There are also other dissimilarities in comparative statics of each industry integration pattern.An indirect method to test the effects of vertical integration on price and volume is presented and empirically tested. Depending on the vertical integration pattern of an industry exogenous shocks have dissimilar effects on prices and outputs of the final and intermediate good. A four equations system is estimated by using Finnish forest industry firm data. Final good demand rise has a reducing effect on both paper and pulp prices. Stumpage prices (upstream marginal costs) have a negative impact on paper and pulp production and a positive impact on prices. These effects from upstream (downstream) stage into downstream (upstream) market should not occur when all firms are unintegrated.This is a revised version of a paper which was presented at seminars at Brussels, Turku, Vienna, and Stuttgart. I would like to thank seminar participants (specially Frank Schmid) and anonymous referees for helpful comments. Financial support from the Marcus Wallenberg Foundation is gratefully acknowledged. 相似文献

We present a growth model of international trade in which expectations about profitability and growth influence innovation and investment. Adaptive learning dynamics determine transition paths for countries with differing structural parameters. Countries limiting trade by tariffs on imports of capital goods can experience gains in growth and perceived utility for a finite time, whereas the rest of the world is adversely affected. Asymmetric gains persist longer when structural advantages of the country applying tariffs are larger. Substantial differences in levels of innovation, output and utility can appear within our asymmetric country setting. 相似文献

This paper demonstrates the use of conceptual modelling to assist with the competence development of adult learners with interrupted occupational and learning careers. The research introduces a self‐evaluation approach used with a group of adult female students in the United Kingdom. The study aimed at increasing learners' awareness of the qualities and nature of their individual learning processes. The paper applies Kontiainen's dynamic concept analysis modelling method as a tool to assist individual students in the evaluation of their personal competences in learning. The findings of the current study suggest that providing adult learners with opportunities to evaluate their own competences may facilitate a process of making their skills visible to themselves as well as to their tutors and employers. This aims to increase their motivation to use and develop their competences. The paper provides an example and a demonstration of the self‐evaluation process in action illustrated by two case studies. 相似文献

This paper examines whether the adoption of stock option plans results in changes in shareholders’ wealth, and whether the stock market reactions to ESOP announcements could be explained by the target group of ESOP and the dilution effect. Short-horizon test methods are applied for this purpose. The sample consists of ESOP announcements of Finnish publicly quoted companies on the Helsinki Stock Exchange during the time period 1988–1998. The event study results show a slightly positive market reaction to announcements of ESOPs targeted to management and a negative market reaction in the case of ESOPs targeted to all employees. The results of regression analysis show that the ESOPs with limited dilution convey positive information to the stock market and the dilution effect has a negative impact on stock returns, especially in the case of ESOPs targeted to all employees. 相似文献

In this article we theorize and conceptualize the recent convergence of management accounting (MA) and financial accounting (FA) with the advancements in information technology (IT), and explicate not only how this convergence is manifested in the technical and technological domain, but also how it is reflected in their convergence at the behavioral and organizational level.Drawing on the analytical model by Hemmer and Labro (2008), in which the forward-looking perspective of FA leads to forward-looking MA, we build a conceptual framing to analyze this convergence. According to this framing, information technology (IT) serves as a facilitator, catalyst, motivator, or even an enabler for the convergence of MA and FA. We further argue that convergence is a much broader phenomenon than claimed by Hemmer and Labro. It firstly covers the technical and technological domain, including the intentional integration of information systems and software, as well as the intentional combination of methods or standards, extending thereafter to the behavioral and organizational domain with the (un)intentional alignment regarding both functions and processes as well as the (un)intentional convergence regarding both work and roles. The applicability of this conceptual framing is illustrated with a set of examples.We present illustrations of the manifestations and outcomes of convergence in both the technical and technological domain (related to accounting standards, discretionary reporting, performance measurement, transfer pricing, competitor, customer and contractor analysis, due diligence in M&As), and the behavioral and organizational manifestation domain (related to accounting processes, work and the role of accountants, incentive systems, accounting and control in multinational companies, the control of business networks, the board of directors and venture capitalists). Based on our observations, we conclude that the forward-looking FA elements are often intertwined with MA, and vice versa, and that convergence in the technical and technological domain appears to precede convergence in the behavioral and organizational domain. In most of our observations, IT plays an important or even crucial role in this convergence process. In the light of these convergence observations, we open several avenues for further research. 相似文献

This paper examines complex service offerings and the creation of systemic customer value in such settings. We explore the extent to which customers value systemic offerings as opposed to more separated offerings. We conducted a questionnaire survey within the customer base of two Finnish service companies. We utilized t-tests to find out how systemic offerings and separated offerings differed in terms of perceived customer value along different dimensions. The findings support the claim that systemic offerings are valued more than offerings that are more separated in nature. The results of the study carry practical implications for firms offering complex and integrated service solutions. In addition, analyses of the service-value elements included in the offering and of the related customer value will enable firms to optimize their service provisioning so as to give higher customer value and subsequently enhance their competitive advantage. 相似文献

Convergence for difference equations with vanishing time-dependence, with applications to adaptive learning 总被引:1,自引:1,他引:0
Summary. We provide conditions for local stability and instability of an equilibrium point in certain systems of nonautonomous nonstochastic
difference equations. In the systems under study the influence of time is present through a positive scalar “gain” parameter
which converges in the limit to zero. These systems have recently been used to study the dynamics of adaptive learning in
economic models, and we provide two economic illustrations of the formal results.
