The paper focuses on multi-period aspects of risk functionals. It discusses properties, provides dual representations and offers methods for constructing multiperiod risk functionals. On the way, existence results and representations for conditional risk mappings are derived. In particular, conditional, multi-period and nested versions of the average value-at-risk are given. Finally, the import...

The current paper develops three different ways to measure the multi-period global cost efficiency for homogeneous networks of processes when the prices of exogenous inputs are known at all time periods. A multi-period network data envelopment analysis model is presented to measure the minimum cost of the network system based on the global production possibility set. We show that there is a rel...

in very recent papers asmild et al. (2003) and halved et al. (2004) based upon potential improvement efficiency index (bogetoft and hougaard,1999) have suggested an alternative nonparametric frontier approach namely multi-directional inefficiency analysis (mea) to estimate the performance efficiency. mea has many advantages over data envelopment analysis (dea) as the standard nonparametric fron...

We formulate a dynamic model of voluntary investment in a public project. We distinguish two alternative scenarios. One in which private agents have full knowledge about the accumulated aggregated contributions and one in which each agent only has knowledge about his personal contributions. For both scenarios we investigate whether or not the public project will be efficiently funded by the age...

We report on numerical results for certain families of S-unimodal maps with flat critical point. For four one-parameter families, differing in their amount of flatness, we study the Feigenbaum-limits α and δ. There seems to be a finite δ and a finite α associated with each period doubling cascade in each family. Some rough numerical estimates are obtained. One would expect that these numbers sh...

In a competitive market, semiconductor fabricator must face an environment with multi-product types, multi-priority orders and demand changes in time. Since semiconductor fabrication has a very complicated production process, the above-stated characteristics make the production planning even more difficult. This paper applies data envelopment analysis (DEA) to find a set of product family mix t...

This paper discusses the design characteristics management accounting systems should have to be useful for strategic planning and control and provides brief introductions to strategic variance analysis and profit-linked performance measurement models. It shows two multi-period, multi-product models (Banker, Chang and Majumdar 1993; Banker and Johnston 1989) are specified, can be related to Port...
