Some personal views on the current state and the future of locational analysis
1998
In this paper a group of participants of the 12th European Summer Institute which took place in Tenerife, Spain in June 1995 present their views on the state of the art and the future trends in Locational Analysis. The issues discussed include modeling aspects in discrete Location Theory, the influence of the distance function, the relation between discrete, network and continuous location, heuristic techniques, the state of technology and undesirable facility location. Some general questions are stated regarding the applicability of location models, promising research directions and the way technology affects the development of solution techniques.
Estimating the non-market benefits of an urban park: Does proximity matter?
2007
Abstract There is increasing and widespread public support for public park provision in urban areas given that they provide an array of different recreational activities enhancing the citizen's quality of life. A contingent valuation survey of 900 randomly chosen inhabitants was undertaken in Valencia (Spain) to estimate the non-market benefits derived from the provision of a new urban park where there is currently an old train station. In conducting our study we distinguished between the districts of the city more and less affected by the project according to the proximity to the future park. Our main finding is that the mean willingness to pay (WTP) is considerably higher for people who l…
Reasons for Clustering of Creative Industries in Italy and Spain
2012
Creative industries and creative employment tend to concentrate around medium and large cities, forming creative local systems. We follow a multidisciplinary approach, based on cultural and creative economics, evolutionary geography and urban economics, in order to analyse the forces behind the clustering of employment in creative industries in a comparative analysis of Italy and Spain. The results show different patterns of clustering of creative employment in both countries. The historical and cultural endowments, the average size of creative industries, the size of the place, the productive diversity, and the concentration of human capital and creative class have been determined to be co…
On Pareto optima, the Fermat-Weber problem, and polyhedral gauges
1990
This paper deals with multiobjective programming in which the objective functions are nonsymmetric distances (derived from different gauges) to the points of a fixed finite subset of ℝn. It emphasizes the case in which the gauges are polyhedral. In this framework the following result is known: if the gauges are polyhedral, then each Pareto optimum is the solution to a Fermat—Weber problem with strictly positive coefficients. We give a new proof of this result, and we show that it is useful in finding the whole set of efficient points of a location problem with polyhedral gauges. Also, we characterize polyhedral gauges in terms of a property of their subdifferential.
No room for males in caves: Female-biased sex ratio in subterranean amphipods of the genus Niphargus.
2021
Sex allocation theory predicts that the proportion of daughters to sons will evolve in response to ecological conditions that determine the costs and benefits of producing each sex. All else being equal, the adult sex ratio (ASR) should also vary with ecological conditions. Many studies of subterranean species reported female-biased ASR, but no systematic study has yet been conducted. We test the hypothesis that the ASR becomes more female-biased with increased isolation from the surface. We compiled a data set of ASRs of 35 species in the subterranean amphipod Niphargus, each living in one of three distinct habitats (surface-subterranean boundary, cave streams, phreatic lakes) representing…
Regional Economics Tools applied to Sport: New Perspectives
2007
This article shows how some regional economics tools, which are not very well known, can be used in the field of sport. The first part consists of a short summary of the location analysis models. In a second part, we show on a case study, that computable location models can be used to determine the optimal location of sporting facilities in the context of intercommunity. To conclude, some extensions are suggested from a theoretical point of view as well as for empirical applications.
On the Location and 'Lock-In' of Cities: Geography vs. Transportation Technology
2004
We investigate where cities are located in a spatial economy and why they tend to get 'locked-in' at particular sites. Building on Fujita and Krugman (1995) we show that geography and/or transportation technology must exhibit some 'non-smoothness' for cities to possibly become 'locked-in' in location space. Our results establish that no asymmetric monocentric equilibrium can be generically sustained when space is homogenous and transportation technologies are 'smooth', whereas it can in the presence of transportation hubs and/or concave transport cost functions. This suggests that cities are drawn to transportation hubs during the early stages of economic development, whereas they can be su…
Constrained and unconstrained problems in location theory and inner products
1997
In a real normed space X the optimization problem associated to a finite subset and to a family of positive weights with the objective function [UM0001] has some well known properties when X is an ...
Is tourism firm competitiveness driven by different internal or external specific factors?: New empirical evidence from Spain
2015
Abstract The quest to understand the multilevel antecedents of competitiveness has led to a separation of approaches. On one side of the question are the environment theories that analyze the structural characteristics of the general and competitive environment. On the other side are the Resource Based View and its extensions that highlight firm-specific resources and capabilities as the main basis of firms' competitiveness. However, in recent years the nature of competition and shifting economic conditions have given rise to new theoretical approaches that complement the assumptions underlying both environmental and firm theories. Specifically, this study contributes by examining the regio…
The effect of hotel chain affiliation on economic performance: The moderating role of tourist districts
2020
Abstract This paper offers a pioneering analysis of the impact that integration in different types of hotel chains has on firm performance, and the moderating effect of the tourist destination in this relationship. Studies in the literature examine both size and location independently, without reconciling the apparently contradictory trends of globalization and conservation of the local base. The aim of the research is to analyze the comparative effects on tourism firms’ performance of belonging to different types of hotel chains while maintaining the advantages of location in a tourist destination. Based on a study of 292 Spanish hotels, the authors test the proposed hypotheses using hiera…
