This paper analyses the relation between competition and concentration in the banking sector. The empirical answer is given by testing a monopolistic competition model of bank branching behaviour on individual bank data at county level (départements and provinces) in France and Italy. We...

We examine the firm- and country-level determinants of the currency denomination of small business loans. We first model the choice of loan currency in a framework which features a trade-off between lower cost of debt and the risk of firm-level distress costs, and also incorporates the impact of...

We model the impact of bank mergers on loan competition, reserve holdings and aggregate liquidity. A merger creates an internal money market that affects reserve holdings and induces financial cost advantages, but also withdraws liquidity from the interbank market. We assess changes in liquidity...

In this paper we consider the case for subsidies towards firms which generate R&D spillovers in open economies. We show that in the presence of strategic behaviour by firms many expected results are overturned. Local R&D spillovers to other domestic firms may justify an R&D tax rather than a...

This paper examines the rationale for multilateral agreements to limit investment subsidies. The welfare ranking of symmetric multilateral subsidy games is shown to depend on whether or not investment levels are "friendly", raising rival profits in total, and/or strategic complements, raising...

Empirical evidence strongly suggests that R&D increases a firm’s ‘absorptive capacity’ (its ability to absorb spillovers from other firms) as well as contributing directly to profitability. We explore the theoretical implications of this. We specify a general model of the absorptive...

We evaluate the social welfare loss (WL) that arises in an oligopolistic industry under technological competition and product differentiation. The main novelty of our approach concerns the decomposition of the WL into `dynamic' losses (from too little cost reduction and an inappropriate number...

This paper evaluates the effects of liberalizing access to the space sector, as currently envisaged by the EC Commission. We undertake an econometric evaluation of the degree of scale economies in satellite operations and calibrate a Cournot model of competition in which the effect of...
