sovereign wealth funds cross border investments assessing the role of country level drivers and Spatial Competition
Journal of International Money and Finance, 2017Co-Authors: Nicolas Debarsy, Jeanyves Gnabo, Malik KerkourAbstract:Abstract The aim of this paper is to identify the driving forces of cross-border investments emanating from Sovereign wealth funds and to test the existence of Spatial Competition among recipient countries. For this, we develop an original econometric framework that quantifies the role of Spatial dependence in the location of investments, and that uses a modified version of the standard estimation procedure of Spatial panel model, which accommodates the Inverse Hyperbolic Sine transformation of the dependent variable. This transformation copes with two critical features of net capital flows, namely an highly skewed distribution and the presence of zero and negative values. Using a large-scale database, we provide evidence of negative Spatial dependence, investments in one country being on average at the expense of its neighbors.

sovereign wealth funds cross border investments assessing the role of country level drivers and Spatial Competition
Research Papers in Economics, 2016Co-Authors: Nicolas Debarsy, Jeanyves Gnabo, Malik KerkourAbstract:The aim of this paper is to identify the driving forces of Sovereign wealth funds' investments. For this, we develop an original econometric framework that quantifies the role of Spatial dependence in the location of investments, and uses the Inverse Hyperbolic Sine transformation of the dependent variable in a Spatial panel model context. This transformation copes with two features of net flows, namely an highly skewed distribution and the presence of zero and negative values. Using a large-scale database, we provide evidence of negative Spatial dependence, investments in one country being on average at the expense of its neighbors.

pricing with cookies behavior based price discrimination and Spatial Competition
Management Science, 2017Co-Authors: Chongwoo Choe, Stephen P King, Noriaki MatsushimaAbstract:We study a two-period model of Spatial Competition with two symmetric firms where firms learn customers’ preferences from the first-period purchase, which they use for personalized pricing in the second period. With product choice exogenously fixed with maximal differentiation, we show that there exist two asymmetric equilibria and customer switching is only from one firm to the other unless firms discount future too much. Firms are worse off with such personalized pricing than when they use pricing at higher levels of aggregation. When product choice is also made optimally, there continue to exist two asymmetric equilibria given sufficiently small discounting, none of which features maximal differentiation. More customer information hurts firms, and more so when they make both product choice and pricing decisions.

product differentiation and entry timing in a continuous time Spatial Competition model
European Journal of Operational Research, 2015Co-Authors: Takeshi Ebina, Noriaki Matsushima, Daisuke ShimizuAbstract:Abstract We extend the well-known Spatial Competition model (d’Aspremont, Gabszewicz & Thisse, 1979) to a continuous time model in which two firms compete in each instance. Our focus is on the entry timing decisions of firms and their optimal locations. We demonstrate that the leader has an incentive to locate closer to the center to delay the follower’s entry, leading to a non-maximum differentiation outcome. We also investigate how exogenous parameters affect the leader’s location and firms’ values and, in particular, numerically show that the profit of the leader changes non-monotonically with an increase in the transport cost parameter.

Spatial Competition and quality evidence from the english family doctor market
Journal of Health Economics, 2019Co-Authors: Hugh Gravelle, Dan Liu, Carol Propper, Rita SantosAbstract:We examine whether family doctor firms in England respond to local Competition by increasing their quality. We measure quality in terms of clinical performance and patient-reported satisfaction to capture its multi-dimensional nature. We use a panel covering 8 years for over 8000 English general practices. We measure Competition as the number of rival doctors within a small distance and control for a large number of potential confounders. We find that increases in local Competition are associated with increases in patient satisfaction and to a lesser extent in clinical quality. However, the magnitude of the effect is small.

Social Science Research Network, 2018Co-Authors: Hugh Gravelle, Dan Liu, Carol Propper, Rita SantosAbstract:We examine whether family doctor firms in England respond to local Competition by increasing their quality. We measure quality in terms of clinical performance and patient-reported satisfaction to capture its multi-dimensional nature. We use a panel covering 8 years for over 8000 English general practices, allowing us to control for unobserved local area effects. We measure Competition by the number of rival doctors within a small distance. We find that increases in local Competition are associated with increases in clinical quality and patient satisfaction, particularly for firms with lower quality. However, the magnitude of the effect is small.
