In this paper we use a simple climate model with endogenous environmental technical change in order to analyse the effects on equity and efficiency of different degrees of restrictions on trade in the market for pollution permits. The model is obtained by incorporating in Nordhaus and Yang...

This paper develops a spatial model for a water basin that allows for surface water allocation and re-use of the water that is lost. The analytical solution suggests specialisation of production over space - upstream farmers use canal water and downstream farmers pump groundwater that is lost...

We explore the effects of environmental taxes that imprecisely target pollution. A review of actual policies indicates few (if any) examples of a true tax on pollution. More typically, environmental taxes target an input or output that is correlated with pollution. We construct a simple...

This paper addresses the question of delegation in an organisation where there is an initial asymmetry of information between the principal and the agent. We assume that the principal cannot use revelation techniques à la Baron Myerson to elicit agent's superior information and in contrast, we...

Spontaneous adoption of cleaner technologies can be slowed down by various sources of inertia. Investment irreversibility, uncertainty about the actual private benefits, and the expectation of declining adoption costs due to the diffusion of environmental innovation, may involve a timing of...

Our interest here concerns liquidity supply as a distinctive feature of the bank-borrower relationship. Any agent facing an opportunity or a commitment may find him/herself unexpectedly illiquid, and hence he/she may find it profitable to borrow "on call" if this costs less than missing the...

We study a long-term relationship between a risk-neutral firm that has been delegated to manage a local utility project and a regulator that has always the option-to-revoke the delegation. We show that when the threat of revocation is credible and the cost of exercising it is not too high, the...

I find that current US's and EU's Antitrust laws -- in particular their "moderate"' leniency programmes that only reduce or at best cancel sanctions for price-fixing firms that self-report -- may make collusion enforceable even in one-shot competitive interactions, like Bertrand oligopolies and...

When modelling data generated from a discrete choice contingent valuation question, the treatment of zero bids affects the welfare estimates. Zero bids may come from respondents who are not interested in the provision of the public good; alternatively, some zero-bidders may be protesting about...
