This paper presents the design and implementation of the GridEcon Marketplace. In addition to supporting a market mechanism for trading computing resources on a pay-per-use basis, this marketplace also provides an environment for integrating value-added support services. These value-added...

This paper analyzes the structural change in the German dairy sector using a sector-wide optimization model. In particular, the model includes a spatially explicit representation of dairy processing farms and dairy farming regions to account for the trade-off between economies of scale in dairy...

Adaptations of simple exponential smoothing are presented that aim to unify the task of forecasting demand for both slow and fast moving inventories. A feature of the adaptations is that they are designed to ensure that the resulting prediction distributions have only a nonnegative domain. A...

In this article we extend the agent-based model of firms’ formation and growth proposed in [4]. In [4] the firms‘ creation, expansion or contraction results from the interaction of heterogeneous utility maximizers. While the original model was able to replicate the power law distribution in...

Much of the research on industry dynamics focuses on the interdependence between the sectorial rates of entry and exit.This paper argues that the size of firms and the reaction-adjustment period are important conditions missed in this literature.I illustrate the effects of this omission using...

Electricity markets are being liberalised and open to private competition in several countries. These liberalized electricity markets are very complex as the interactions between demand and supply are subject to several technicalities arising from the commodity being traded: electricity. One of...

The Ellison-Glaeser (1997) index is an unbiased statistic of industrial localization. Though the expected value of the index is known, ad hoc values are used to interpret the extent of localization. We improve on the interpretation of the index by simulating condence intervals while varying the...
