The 1994 Riegle Neal (RN) Act removed interstate banking restrictions in the US. The primary motivation was to permit geographic risk diversification (GRD). Using a factor model to measure banks' geographic risk, we show that RN expanded GRD possibilities in small states, but that few banks took...

The U.S. banking industry has been characterized by intense merger activity in the absence of economies of scale and scope. We claim that the loosening of geographic constraints on U.S. banks is responsible for this consolidation process, irrespective of value-maximizing motives. We demonstrate...

We put forward a simple spatial competition model to study banks’ strategic responses to the Spanish asymmetric geographic deregulation. We find that once geographic deregulation process finishes, inter-regional mergers between the savings banks are optimal. We claim that the public good...

We consider a duopolistic industry in which pollution is a by-product of production and firms are given emission permits that they can trade. The common wisdom is that allowing for trade in emission permits promotes efficiency. We demonstrate that this common wisdom cannot automatically be...

European and the US mobile communication services markets have developed in rather different ways. There are striking differences in termination regulation and retail pricing models and one may wonder why this occurred and whether either of the markets outperforms the other in terms of...

In this paper we analyse a setup where consumers are heterogeneous in the perception of environmental quality. The equilibrium is verified in a setting with horizontal and vertical (green) differentiation. Profits are increasing in the misperception of quality, while, the investment in green...

We propose a model of environmental overcompliance in a duopoly setting where consumers are environmentally concerned and may patronise the product they buy, firms set their green investment to abate the impact of productivity on pollution and a government sets the environmental standard with...

Initially, the global financial crisis caused a surge of financial inflows, raising Chinese investment but this abated in 2008, to be replaced by a slowdown in export demand. The government’s key response has been to commit to an unprecedented fiscal expansion. Two oft-ignored consequences...
