This paper explores several aspects of the vertical relationship between an upstream firm and a number of downstream firms that are Cournot rivals relying on the inputs provided by the upstream firm. We address the following questions: (i) if the upstream firm can charge different prices to...

Quebec is currently the stage for a series of debates on which investments are required of the government, whether in infrastructure, education, healthcare, etc. Where to begin? What projects to prioritize? These investments give rise to a series of questions, not the least of which is how they...

Sedimentation in river beds, which results in social disamenities, is caused by soil erosion in farmed ecosystems surrounding those rivers. This paper introduces a "spatial"" corrective tax on soil erosion. We find that the optimal tax rule will depart from the classical Pigouvian method...

Agents face an ambiguous risk of biodiversity survival as well as ambiguous expected losses from its extinction. As a collectivity, agents are faced with the option of privately funding the protection of biodiversity for biomedical research. We propose two evolutionary models of threshold public...

This paper focuses on the disparity between willingness-to-pay and willingness-to-accept indices in nonmarket valuation. The substitution effect makes agents value net losses higher than opportunity losses. In regard to net losses, we show that imperfect substitutability respectively induces...

This paper explores methodological issues surrounding the use of discrete choice experiments to elicit values for public goods. We develop an explicit game-theoretic model of individual decisions to a series of choice sets, providing general conditions under which surveys with repeated binary...

We propose different extensions of the continuous record asymptotic analysis for rolling sample variance estimators developed by Foster and Nelson (1996). First, despite the difference in information sets we are able to compare the asymptotic distribution of volatility estimators involving data...

This paper illustrates the usefulness of resampling based methods in the context of multiple (simultaneous) tests, with emphasis on econometric applications. Economic theory often suggests joint (or simultaneous) hypotheses on econometric models; consequently, the problem of evaluating joint...

We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

In a stylized model of international trade, firms in the North indirectly export second-hand products to a representative firm in the South to be reused as intermediate goods, with potential trade gains. The level of reusability of waste products is a crucial choice variable in the North. This...
