Market Concentration in Europe: Evidence based on Antitrust Markets (cancelled)

Abstract:  An increasing body of empirical evidence has documented trends to risen concentration, profits, markups, and market power in many industries across the world since the 1980s. Several factors – such as globalisation, digitisation, the increased role of intangible assets and sunk costs, as well as M&A activity and the (under)enforcement of merger control– have been...

Optimal Benefit-Based Corporate Income Tax

Abstract:   I derive an optimal benefit-based corporate tax rate formula as a function of the public input elasticity of profits and the (net of) tax elasticity of profits. I argue that the existence of the corporate income tax should be justified by the benefit-based view of taxation: firms should pay tax according to the benefits they receive from the use of the public input. I argue that...

Testing the Superstar Firm Hypothesis

The superstar firms model provides a compelling explanation for two simultaneously occurring phenomena: the rise of concentration in industries and the fall of labor shares. Our empirical analysis confirms two of the underlying assumptions of the model: the market share increases and the labor share decreases with increasing firm-level total factor productivity, providing support for the superstar ...

Merger Efficiency Gains: Evidence from a Large Transport Merger in France

Many industries are seeing an increase in concentration, leading to a discussion on the effectiveness of horizontal merger enforcement. The policy debate shows that one of the key arguments put forward when supporting potential mergers is the possibility of realization of merger efficiency gains, specifically in the transport industry. Yet, there exists little empirical evidence on the actual effects ...
