Trade is not necessary for agglomeration to arise
2003
We develop a spatial general equilibrium model in which the absence of trade is an endogenous outcome and we show that trade is not a necessarycondition for agglomeration to arise. More precisely, extending the modeldeveloped by Ottaviano et al. [13], we show that equilibria without tradediffer significantly from those obtained in the presence of trade. Somewhatsurprisingly, equilibrium structures without trade are richer than those withtrade, since partial agglomeration becomes a feasible outcome. Equilibrianow depend on the ratio of mobile to immobile factors and an increase in thatratio triggers a process of spatial agglomeration.
Measuring welfare loss of market power: an application to European banks
2004
From a model of imperfect competition among banking firms, this study derives an analytical expression that allows empirical quantification of the welfare loss associated with imperfect competition. Its application to the specific case of the European banking system shows that in spite of the process of deregulation, market power increased during the 1990s in 10 out of the 15 countries of the EU. The welfare loss associated with market power represents close to 2.5% of EU GDP.
The Role of Intraindustry Trade in Interregional Trade in the Midwest of the US
2007
The subject of international trade among countries has long been of concern to policy makers and academics alike. As economic activity has become more and more international in scope, the potential impact of international trade on regional economic growth and income distribution has become central to many studies. Within economics, the study of industrial organization, particularly with respect to imperfect competition and economies of scale and agglomeration, has influenced developments in international trade theory in the past few decades. In identifying the determinants of trade among countries, issues such as market size, relative level of Gross National Product (GNP) per capita, market…
Welfare, Home Market Effects, and Horizontal Foreign Direct Investment
2005
We investigate the spatial distribution and organization of an imperfectly competitive industry when firms may choose to operate more than a single production unit. Focusing on a short-run setting with a fixed mass of firms, we fully characterize the spatial equilibria analytically. Comparing the equilibrium and the first-best, we show that both organizational and spatial inefficiencies may arise. In particular, when fixed costs are low enough the market outcome may well lead to overinvestment and, therefore, to too many multinationals operating from a social point of view. Furthermore, once multinationals are taken into account, the market outcome may well lead too little agglomeration.
R&D, Competition and Growth with Human Capital Accumulation Revisited
2012
In this paper, we have presented a generalization of Bucci's (2003) model in which have disentangled the monopolistic mark-up in the intermediate goods sector, the intermediate goods share in the final output and the returns to specialization in order to have a better measurement of competition. Indeed, unlike Bucci (2003), in our model, the measure of competition is completely independent of the intermediate goods share in the final output and the returns to specialization. Our main finding is that, unlike Bucci (2003), we show that the competition does not play any role in growth. This result is explained by the complementarity of innovation and human capital assumed in the research produ…
Strategic interactions on differentiated markets and public policies
2017
In economy, the competition analysis among firms have a significance importance because of the complexity of some elements. This thesis examines the strategic interactions on differentiated markets in general equilibrium while proposing the public policies to reduce the distortions due to the imperfect behaviors. This thesis takes into account the differentiation of products in order to obtain the new conclusions and/or to extend those existing. We thus pursues two objectives. Fisrt, the construction of a model of imperfect competition on differentiated markets in a general equilibrium framework. Second, the evaluation of the consequences of the model in terms of economic policies. At begin…
