A manufacturer contracting secretly with several downstream competitors faces an opportunism problem, preventing it from exerting its market power. In an infinitely repeated game, the opportunism problem can be relaxed. We show that the upstream firm's market power can be restored even further...

We consider an infinitely-repeated Bertrand game, in which prices are perfectly observed and each firm receives a privately-observed, i.i.d. cost shock in each period. We focus on symmetric perfect public equilibria (SPPE), wherein any "punishments" are borne equally by all firms. We identify a...

In the past two decades privatisation and liberalisation of network industries providing services of general economic interest (SGEI), have been particularly significant in the European Union. Wide variations around a common policy trend can, however, be observed across countries and sectors. We...

In this paper, we studied the influence of contract renewals on water prices in France. When studying French water contracts in force between 2008 and 2018, we found that contract renewals have little influence on the prices paid by consumers. However, at contract renewal times, the share of the...

We aim to evaluate two different econometric screens for identifying anti-competitive behavior in the fuel retail market: (i) The Markov-Switching GARCH (MS-GARCH) Models; (ii) The Local Gaussian Correlation (LGC) approach. Using the gasoline cartel judged and condemned in Brasília as a...

We study the response of residential water demand to nonlinear prices by exploiting a natural experiment arising from a water pricing reform in a major Chinese city. The reform introduced an unconventional Increasing Block Tariff featuring prices set according to annual cumulative consumption...

Marginal cost pricing of running water and sewerage services has long been the default recommendation of economists and natural resource specialists to firms and local governments. However, water pricing has never been studied simultaneously with the water metering problem before. The socially...

We estimate the price elasticity of water demand with household-level data, structurally modeling the piecewise-linear budget constraints imposed by increasing-block pricing. We develop a mathematical expression for the unconditional price elasticity of demand under increasing-block prices and...
