Where to locate in a circular city?

Barnali Gupta, Fu-Chuan Lai, Debashis Pal, Jyotirmoy Sarkar, Chia-Ming Yu
2004 International Journal of Industrial Organization  
We demonstrate that the equidistant location pattern is only one of the many equilibrium location patterns that arise in a circular market.  ...  We study location choices by Cournot oligopolists in a circular market, where consumers are located uniformly along the circumference.  ...  ) and made popular by Salop (1979) . 4 In the linear city model, the consumers are assumed to be distributed on a line of a …nite length, whereas in the circular city model, the consumers are distributed  ...

Differentiation with User-Generated Content

Kaifu Zhang, Miklos Sarvary
2015 Management science  
We model a Hotelling style market in which consumers have heterogeneous tastes along a circular city.  ...  Finally, we allow multihoming by consumers and show that the previous equilibrium patterns remain valid, but in most equilibria, a subset of consumers (located between rival firms' core clienteles) are  ...  The authors are grateful to Timothy Van Zandt, who provided extremely helpful suggestions in the early stage of this project.  ...

Self-organized agglomerations and transport costs

Pierre M. Picard, Takatoshi Tabuchi
2008 Economic Theory  
We consider a racetrack economic model in which firms and workers freely locate on the continuous space of a circumference.  ...  We also characterize conditions on the shape of transport costs under which discrete distributions are stable equilibria.  ...  Note that in contrast to seamless distributions, this result about agglomeration in a single city does not require any smoothness property on the shape of transport costs.  ...

Inequality, neighbourhoods and welfare of the poor

Namrata Gulati, Tridip Ray
2016 Journal of Development Economics  
We model this interaction by integrating consumers' income distribution with the spatial distribution of their location and explore the consequences of an increase in income inequality on the welfare of  ...  There exist multiple equilibria: a bad equilibrium where all the poor are excluded exists simultaneously with a good equilibrium where at least some poor (if not all of them) get served by the market.  ...  1) ' * A.3 Single-Income Neighbourhood Consider a circular city where there is a measure 1 of consumers with the same income ! distributed uniformly along the city circumference.  ...

Horizontal market concentration: Theoretical insights from spatial models

Andreea Cosnita-Langlais
2012 Research in Economics  
This paper aims to further advance the study of horizontal mergers by critically reviewing the theory on spatial models that may be used for the analysis of horizontal market concentration.  ...  We examine the incentives conveyed by locations for undertaking merger and merger-related strategies, as well as the impact of merger on strategic location choices.  ...  duopoly game on the circular city, with general consumer distribution and transport cost functions.  ...

The Welfare Effects of Location and Quality in Oligopoly

Luis C. Corchón, Galina Zudenkova
2011 Social Science Research Network  
We show that in models where location is endogenous, welfare losses arising from wrong locations or from lack of market coverage may be substantial despite firms competing in prices.  ...  In contrast, welfare losses arising from quality choice are modest but they might vary discontinuously with the size of the market. JEL classification: D61; L11; L13; L50.  ...  in a model where …rms decide on locations.  ...

Urbanization, Energy Consumption and Entropy of Metropolises

Syed Amaar Ahmad, Senior Member, IEEE
2019 Complex Systems  
In this paper, we develop a model of how the population and area of a city affect its energy consumption patterns.  ...  We also show that with urbanization of smaller cities, there is a corresponding increase in the entropy (or variance) of the energy consumption, whereas, for larger cities, the entropy actually diminishes  ...  Acknowledgments The author would like to express appreciation for the review and comments by Abdul Naseer Malmi Kakkada of the University of Texas at Austin.  ...

Majority Voting in Multidimensional Policy Spaces: Kramer-Shepsle versus Stackelberg

PHILIPPE DE DONDER, MICHEL LE BRETON, EUGENIO PELUSO
2012 Journal of Public Economic Theory  
A vector of policies is a Kramer-Shepsle equilibrium if each component coincides with the majority choice on this dimension given the other components of the vector.  ...  We especially stress the importance of single crossing conditions, and we identify two variants of these assumptions: a marginal version that is imposed on all policy dimensions separately, and a joint  ...  We assume that the unit cost of production of the public good is one, that there is a mass one of consumers, and that public provision is nanced with a lump sum tax.  ...

On Metropolis Growth [article]

Syed Amaar Ahmad
2017 arXiv   pre-print
We show that with a constant metropolis area (fixed s), the variance and entropy of consumed energy initially increase with n, reach a maximum and then eventually diminish to zero as saturation is reached  ...  We abstract a city in terms of two fundamental variables; s resource cells (of unit area) that represent energy-consuming geographic or spatial zones (e.g. land, housing or infrastructure etc.) and a population  ...  The cells are located in a pattern which may be square, circular or some other regular shape.  ...

Why do all the flights leave at 8 am?: Competition and departure-time differentiation in airline markets

Severin Borenstein, Janet Netz
1999 International Journal of Industrial Organization  
We find a negative relationship in both periods.  ...  Theoretical models of spatial product differentiation indicate that firms face two opposing incentives: (1) minimize differentiation in order to "steal" customers from competitors, and (2) maximize differentiation  ...  Acknowledgements We thank Jon Haveman, Phil Howrey, Peter Reiss, Nancy Rose, two anonymous referees and seminar audiences at the University of Illinois, Harvard, MIT, and Stanford.  ...

Helical core tokamak MHD equilibrium states

W A Cooper, J P Graves, O Sauter, J Rossel, M Albergante, S Coda, B P Duval, B Labit, A Pochelon, H Reimerdes
2011 Plasma Physics and Controlled Fusion  
Novel equilibrium states that can model the snake are obtained for a JET configuration when the q-profile has weak reversed magnetic shear with minimum q values in the range 0.94 to 1.03.  ...  When a peaked pressure profile is chosen, the helical core structures appear like the snakes that are observed in the JET tokamak. They also have the allure of saturated ideal internal kinks.  ...  We are very grateful to S P Hirshman for his invaluable contributions to the development of the 3D equilibrium solvers we use which has made this research possible.

Trade liberalisation and agglomeration with firm heterogeneity: Forward and backward linkages

Toshihiro Okubo
2009 Regional Science and Urban Economics  
This paper studies the impact of trade costs reduction on geographical concentration in the presence of firm heterogeneity and overhead type of export fixed costs.  ...  Also, trade liberalisation never produces a perfect convergence in welfare for the periphery, which loses, and the core, which gains.  ...  One of the common difficulties in VL and CP models are analytically unsolvable equilibria.  ...
