Increasing block tariffs seek a cross-subsidy mechanism between the water network users, based on the common assumption of weak water price elasticity. In Manaus, the capital city of the Brazilian state of Amazonas where most of the 1.6 million dwellers are supplied through the municipal water...

This article proposes a new empirical methodology for computing a cross-market volatility index - coined CMIX - based on the Factor-Dynamic Conditional Correlation (DCC) model, implemented on volatility surprises. This approach solves problems in treating high-dimensional data and estimating...

This paper examines empirically whether nonlinearities play a significant role in the modeling of the carbon price. We highlight the limits of previous carbon markets analyses based essentially on a linear econometric framework. Instead, we propose to revisit the main results on carbon pricing...

We study the impact of competition and environmental policy (feed-in tariff vs. the EU ETS) on investment, CO2 emissions and welfare in an electricity sector. We consider different market structures (a planner who maximises social welfare vs. duopoly) and two types of consumers (those whose...

The interdependency of socio-ecological systems and the increased reach of human activity have led to major political and scientific challenges in the governance of environmental resources. This chapter reviews the state of our knowledge on the matter. The chapter begins by discussing the...

This paper analyzes the special features of electricity spot prices derived from the physics of this commodity and from the economics of supply and demand in a market pool. Besides mean-reversion, a property they share with other commodities, power prices exhibit the unique feature of spikes in...

Portfolio theories are meant to provide a method for managing assets and constructing portfolios. Meanwhile, the mean-variance technique has been heavily criticized by some academics, and its application to real estate portfolio is questionable (Cheng and Liang, 2000). Indeed, the mean-variance...

In this article, we propose to revisit the concept of strategic alignment in a practice-based perspective. We propose new insights on this concept which has mostly been studied in the literature through Henderson and Venkatraman’s strategic alignment model (1993). In a grounded approach, we...

This article is centred on the volatility of commodity prices. It presents the instruments offering a protection against volatility and shows how they can be employed. The first section exposes these derivative instruments. It distinguishes them in step with the need they respond and the way...
