This study investigates the short-run impact of COVID-19 pandemic on number domestic overnight stays at regional level in summer season 2020. Official data for 65 regions four countries are used analysis (Austria, Czech Republic, Germany and Switzerland). Dynamic panel models employed to estimate a tourism demand equation (real GDP price fluctuations) augmented by average temperatures. Estimati...

The paper extends a dynamic version of the classical von NeumannMorgenstern setting to incorporate a degree of confidence in or subjectivity of probabilistic beliefs. It provides a simple axiomatic characterization of a new preference representation that addresses ambiguity from a simple perspective, employing only basic tools from risk analysis. Conceptually, the paper renders the concept of s...

Both climate change and technical change are uncertain. In this paper we show the importance of including both uncertainties when modeling for policy analysis. We then develop an approach for incorporating uncertainty of technical change into climate change policy analysis. We define and demonstrate a protocol for bottom-up expert assessments about prospects for technologies. We then describe a...

Nonmarket valuation is commonly applied to infer the preferences of individuals for restoration policies after an environmental disaster. A crucial issue in this task is to determine the appropriate lapse of time after which the valuation techniques should be applied. This study investigates the role of the emotional load in explaining the dynamic patterns of elicited preferences. The results s...

Notwithstanding great progress in scientific and economic understanding of climate change, it has proven difficult to forge international agreements because of free-riding, as seen in the defunct Kyoto Protocol. This study examines the club as a model for international climate policy. Based on economic theory and empirical modeling, it finds that without sanctions against non-participants there...

This paper introduces endogenous and directed technical change in a growth model with environmental constraints. The final good is produced from "dirty" and "clean" inputs. We show that: (i) when inputs are sufficiently substitutable, sustainable growth can be achieved with temporary taxes/subsidies that redirect innovation toward clean inputs; (ii) optimal policy involves both "carbon taxes" a...

Beaucoup d’études économétriques évaluent l’impact du changement climatique sur l’agriculture en supposant les prix agricoles exogènes. Si variables climatiques influencent ces prix, il résulte un « biais de », dont on reconnaît l’existence mais qui n’a jamais été quantifié. Nous quantifions ce dans le cas Burkina Faso, avec panel 45 provinces et 14 années, pour trois céréales plus cultivées : ...
