We examine the impact of uncertainty on employment dynamics. Alternative measures of uncertainty are constructed based on the survey of professional forecasters, and regression-based forecasting models for GDP growth, inflation, S&P500 stock price index, and fuel prices. Our results indicate...

Under standard assumptions, optimum commodity taxation (OCT) should target non-renewable resources (NRRs) in priority. NRRs should be taxed at a higher rate than otherwise-identical conventional commodities. NRR substitutes and complements should receive a particular tax treatment. When reserves...

We borrow standard assumptions from the non-renewable-resource-taxation and from the directed-technical-change literatures, to take a full account of the incentives to perform R&D activities in a dirty-resource sector and in a clean-resource-substitute sector. We show that a gradual rise in the...

We analyze the consequences of activism in a regulated industry where the regulator has been captured by the industry. Unlike ordinary economic agents, activists are insensitive to monetary incentives. Moreover, they are less well informed than regulators and their actions generate dead-weight...

Demand for oil is very price inelastic. Facing such demand, an extractive cartel induces the highest price that does not destroy its demand, unlike the conventional Hotelling analysis: the cartel tolerates ordinary substitutes to its oil but deters high-potential ones. Limit-pricing equilibria...

Activist NGOs increasingly oppose industrial projects that have nevertheless been approved by public regulators. To understand this recent rise in NGO activism, we develop a theory of optimal regulation in which a regulated industry seeks to undertake a project that may be harmful to society. On...
