The purpose of this paper is to discuss the use of Value Efficiency Analysis (VEA) in efficiency evaluation when preference information is taken into account. Value efficiency analysis is an approach, which applies the ideas developed for Multiple Objective Linear Programming (MOLP) to Data Envelopment Analysis (DEA). Preference information is given through the desirable structure of input- and output-values. The same values can be used for all units under evaluation or the values can be specific for each unit. A decision-maker can specify the input- and output-values subjectively without any support or (s)he can use a multiple criteria support system to assist him/her to find those values on the efficient frontier. The underlying assumption is that the most preferred values maximize the decision-maker's implicitly known value function in a production possibility set or a subset. The purpose of value efficiency analysis is to estimate a need to increase outputs and/or decrease inputs for reaching the indifference contour of the value function at the optimum. In this paper, we briefly review the main ideas in value efficiency analysis and discuss practical aspects related to the use of value efficiency analysis. We also consider some extensions. 相似文献

Joint value creation through partnering and networking is a topic of current interest. This paper proposes that the dimensions of the supplier's value creation in a supplier-customer relationship could be classified according to efficiency, effectiveness and network functions. These functions are interrelated, but they are conceptually distinct. The value creation process could be described as a spectrum ranging from core value, to added value, to future value. The value-producing potential of a supplier can be assessed reasonably well only in the case of the core value, where there is sufficient benchmarking information in the form of existing alternative offerings and solutions. A priori evaluation of the costs and benefits of added value and, especially, future value projects is problematic, because the realisation of the value is dependent on the development of multiple partners, technologies and industries. In these cases, we suggest that a customer could use a supplier's capability profile as an indicator of how suitable that particular supplier is for specific value creation projects. A framework connecting specific capabilities to different types of value production is suggested, and its managerial implications are discussed. 相似文献

We study a bilateral negotiation set-up where, at a bargaining impasse, the disadvantaged party chooses whether to escalate the conflict or not. Escalation is costly for both parties, and it results in a random draw of the winner of the escalated conflict. We derive the behavioral predictions of a simple social utility function, which is convex in disadvantageous inequality, thus connecting the inequity aversion and the prospect theory models. Our causal laboratory evidence is, to a large extent, consistent with the predicted effects. Among other things, the model predicts that the escalation rate is higher when escalation outcomes are riskier, and that the disagreement rate is lower when the cost of escalating the conflict is higher. 相似文献

Hiring Older Employees: Do the Age Limits of Early Retirement and the Contribution Rates of Firms Matter? 下载免费PDF全文
We examine the effects of a Finnish pension reform on firms' incentives to hire older employees. The reform restricted the eligibility ages for early retirement and changed the size‐related contribution rates of firms. According to our theoretical model, the positive effect on the values of new hires extends to age groups younger than those directly affected by the reform, and the effects are strongest in the largest firms. These model predictions were confirmed in a difference‐in‐difference‐in‐differences analysis on the probability of the hiring of workers of different ages in firms of different sizes. 相似文献

Pervasive information and communication technology (ICT), intertwined with global dispersion of supply chains, is inducing
a sizable structural transformation. All the articles in this special issue highlight that even though technology is the key
driver, the reactions of businesses and countries to these transformations will depend on economic, political, and social
arrangements within each organization and society. The competitive landscape of the ICT industry itself is likely to remain
in flux. Also in other industries, both value creation and value capture are becoming increasingly complex—and remain more
favorable for the developed countries than some commonly used measures suggest. According to the prevailing economic thinking,
public policies should set market-friendly “rules of the game” and then stay out of the way. In the ICT domain, technical
standards, spectrum allocations, and market power associated with various types of lock-ins play crucial roles calling for
more active public involvement. In particular, the dynamic aspects of competition and anti-trust policies are important yet
complex. While there is limited scope for sectoral or horizontal industrial policies, this special issue provides alternative
avenues for considering matrix or systemic policies emphasizing education, openness, and national competitiveness. 相似文献

We examine whether firms and their employees benefit from age and educational diversity. At the plant level we explain productivity
with workforce characteristics. Age diversity is positively and educational diversity negatively related to total factor productivity.
These conclusions are robust to using alternative estimators (fixed effects, GMM, and Olley-Pakes approach). Individual gains
are evaluated by estimating earnings equations with job match fixed effects. The explanatory variables include individual
demographic variables, plant-level workforce characteristics and variables that describe the individuals’ relative position
in the age, education, and gender structure of the plant. Plant-level diversity does not have a significant effect on individual
wages. However, being different from others in terms of age, i.e. relational demography, is positively related to wage. 相似文献

The output of a free resource, like Open Source programming or basic research, may influence the firm’s revenue by reducing
costs or through market interaction. Under moral hazard, if the principal determines how much to utilize the free resource,
he will utilize it more, profits are higher and the agent’s effort is lower than when the agent makes the decision. Contrary
to the standard result, the incentive coefficient is increasing in the variance of the free resource’s output. Utilization
of the free resource and the agent’s effort are always substitutes. 相似文献
