This paper presents an analysis of the recent developments of average market power in Europe by using a broad firm-level database for EU member states. To indicate competitive pressure at the firm-level, markups are estimated following De Loecker (2011), and De Loecker and Warzynski (2012). The...

The study of market power has gained a lot of attention by scholars and policy-makers since De Loecker and Eeckhout (2018).

Over their two years of existence since deregulation began, the electricity markets operated by the California Power Exchange [PX] and Independent System Operator [ISO] have often seen wide price fluctuations and numerous episodes of prices clearly above marginal costs of generation. Both...

In this paper, we provide an assessment of the evolution of markups in Italy in the last twenty years. To this aim, we resort to both macro and micro data and estimation techniques, namely reduced forms accounting measures (price-cost margins) and production function model-based indicators. When...
