Sources of Large Firms’ Market Power and Why It Matters
Filippo di Mauro, Matthias Mertens, Bernardo Mottironi
VOXEU COLUMN,
January
2023
Abstract
Excessive market power has detrimental effects on the functioning of the economy, raising consumer prices, distorting the allocation of resources, and creating welfare losses. The existing literature has largely focussed on competition in product markets. This column argues that it is important to differentiate between various sources of firm market power on output and input (most notably labour) markets. European firm-level data reveals that large firms charge lower markups in product markets but exert their market power significantly in labour markets. Competition authorities can and must distinguish between the sources of market power when attempting to regulate it.

The Impact of Financial Transaction Taxes on Stock Markets: Short-Run Effects, Long-Run Effects, and Reallocation of Trading Activity
Sebastian Eichfelder, Mona Noack, Felix Noth
National Tax Journal,
Nr. 3,
2022
Abstract
We investigate the French 2012 financial transaction tax (FTT) and find robust evidence for anticipation effects before the implementation date. Controlling for short-run effects, we only find weak evidence for a long-run reduction in trading activity. Thus, the main impact of the French FTT on trading activity is short-run. In line with liquidity clientele effects, we find a more potent effect for low-liquidity stocks and a reallocation of trading to high-liquidity stocks from the Supplemental Liquidity Provider (SLP) program. Finally, we find weak evidence for a persistent volatility reduction but no indication of a significant FTT impact on price efficiency.

Organised Labour, Labour Market Imperfections, and Employer Wage Premia
Sabien Dobbelaere, Boris Hirsch, Steffen Müller, Georg Neuschäffer
IWH Discussion Papers,
Nr. 20,
2022
publiziert in: ILR Review
Abstract
This paper examines how collective bargaining through unions and workplace co-determination through works councils relate to labour market imperfections and how labour market imperfections relate to employer wage premia. Based on representative German plant data for the years 1999–2016, we document that 70% of employers pay wages below the marginal revenue product of labour and 30% pay wages above. We further find that the prevalence of wage mark-downs is significantly smaller when organised labour is present and that the ratio of wages to the marginal revenue product of labour is significantly bigger. Finally, we document a close link between labour market imperfections and mean employer wage premia, that is wage differences between employers corrected for worker sorting.

Arbeitsmobilität gehört zum Strukturwandel
Der Kohleausstieg wird die betroffenen Regionen auch dadurch verändern, dass ein Teil der Beschäftigten abwandert. Die Politik sollte diesen Prozess bei der Strukturpolitik berücksichtigen, denn vollständig verhindern lässt er sich nicht. Das verdeutlicht eine vom Leibniz-Institut für Wirtschaftsforschung Halle (IWH) veröffentlichte Studie an einem historischen Beispiel.
