The equalization effects of transfer systems has been the subject of analyses to evaluate the effectiveness of redistribution policies and of the adequacy of revenue sharing mechanisms in providing sub national governments with adequate resources to undertake their public responsibilities....

The objective of the current paper is to analyze the impact of the European Union (EU) funds on gross domestic product (GDP) and employment in the Azores. The theoretical model is based on a modeling platform for the Azorean economy, supported by a dynamical multi-sector computable general...

We introduce a distribution center location model that incorporates joint replenishment inventory costs at the distribution centers. The model is formulated as a Fixed Charge Location Problem (FCLP) which objectively considers not only location specific costs but also inventory replenishment...

One of the assumptions of the Capacitated Facility Location Problem (CFLP) is that demand is known and fixed. Most often, this is not the case when managers take some strategic decisions such as locating facilities and assigning demand points to those facilities. In this paper we consider demand...

Previous covering models for emergency service consider all the calls to be of the same importance and impose the same waiting time constraints independently of the service's priority. This type of constraint is clearly inappropriate in many contexts. For example, in urban medical emergency...

In this paper we propose a metaheuristic to solve a new version of the Maximum Capture Problem. In the original MCP, market capture is obtained by lower traveling distances or lower traveling time, in this new version not only the traveling time but also the waiting time will affect the market...

This study aims to analyse the behaviour of fuel prices at the pump (unleaded gasoline and diesel) in Portugal, relative to positive and negative variations in Brent crude oil price. Applying an Autoregressive Distributed Lags (ARDL) model to weekly time series data for the period of January...

We examine the issue of sensitivity with respect to model parameters for the problem of utility maximization from final wealth in an incomplete Samuelson model and mainly for utility functions of power-type. The method consists in moving the parameters through change of measure, which we call a...
