Vertical Separation v. Independent Downstream Entry in the Spanish Electricity Network: An Experimental Approach
2007
We present experimental results from a series of sessions organized using the Power Market simulator; a software designed to realistically replicate the Spanish Electricity Market. In the experiments reported here we compare the status quo to two alternative treatments which represent alternative market structures. In one of them, labeled as vertical separation, we assume that power generating firms and electricity distributors-endsuppliers belong to separate business groups. In the second, we study the effect of entry by independent end-suppliers. Both alternative scenarios dominate the status quo in terms of market efficiency, whereas the latter of them dominates the former.
EXPLANATORY FACTORS OF MARKET POWER IN THE BANKING SYSTEM
2007
The aim of the study is to analyse the explanatory factors of market power in the banking system. Using as laboratory the Spanish banking system in the period 1986–2002, results show an increase of market power from the mid-1990s. Of the set of variables that the model posits as explaining market power, those with the greatest explanatory power are size, efficiency and specialization; concentration is not significant. This last result shows the limitations of the approaches, studies and decision-making rules of economic policy that uses market concentration as a proxy for the degree of competition.
