Horizontal mergers are usually under the scrutiny of antitrust authorities due to their potential undesirable effects on prices and consumer surplus. Ex-post evidence, however, suggests that not always these effects take place and even relevant mergers may end up having negligible price effects....

We study the optimal contracts (payment and extraction path) implemented by a regulator unable to commit to long term contracts that delegates the extraction of a nonrenewable resource to a firm. The regulator wishes to maximize the tax revenue and does not know the firm’s efficiency which is...

We explore the effects of competitive incentives and of their time horizon on the evolution of both asset prices and trading activity in experimental asset markets. We compare i) a no-bonus treatment based on Smith, Suchanek and Williams (1988) ; ii) a short-term bonus treatment in which bonuses...

Despite the increased strategic importance of environmental innovation on the one hand and corporate social responsibility on the other, there are still few studies that show firm voluntary measures create a primary determinant of environmental changes. First, we clarify the meaning of voluntary...

We study the economics of Bitcoin transaction fees in a simple static partial equilibrium model with the specificity that the system security is directly linked to the total computational power of miners. We show that any situation with a fixed fee is equivalent to another situation with a...

We compare inequality aversion in individuals and teams by means of both within- and between-subject experimental designs, and we investigate how teams aggregate individual preferences. We find that team decisions reveal less inequality aversion than individual initial proposals in team...

Some countries allow physicians to balance bill patients, that is, to bill a fee above the one that is negotiated with, and reimbursed by the health authorities. Balance billing is known for restricting access to physicians’ services while supplemental insurance against balance billing amounts...

Due to the strong polarisation of economic activities in space and rise in collaborative behaviour, increasing attention has recently been devoted to the relationship between geography and network formation. The studies conducted on this topic reveal a high variation in terms of methodologies....

We use laboratory experiments with human subjects to test the relevance of different inflation targeting regimes. In particular and within the standard New Keynesian model, we evaluate to what extent communication of the inflation target is relevant to the success of inflation targeting. We find...
