The 4th cover states: "Will the Grand Paris Express bring the considerable benefits expected by the community and under what conditions? Based on the most recent knowledge on the subject, this book proposes seven theses. The Grand Paris Express represents a technological revolution, revolutionizing the role of public transport in the Paris conurbation. After a debate that is now outdated, it has become a reality, and it will be a powerful urban transformer and a lever for growth for the capital region and the country. It is an investment with a high potential return for the national economy and public finances, but its implementation must be managed on the basis of the most recent knowledge of megaproject management in order to best control the changes in costs and deadlines that are common in this type of project. It is an illustration of what economics can contribute today to inform public debate and collective decision-making. To this end, the book proposes to evolve the framework of economic calculation and decision-making processes to take into account both the richness and complexity of the knowledge required today to correctly apprehend large-scale projects such as the Grand Paris Express, and the need for public opinion to share the issues at stake in modern democracies, at all stages of the decision and implementation process.

Reducing energy consumption in the residential sector is a major challenge in the context of energy transition and the fight against climate change. However, despite the public policies in place, French sectoral energy consumption is struggling to fall. Through four empirical tests, this thesis looks at the obstacles to the reduction of energy consumption in the French residential sector, focusing on the role of individual factors. In the first chapter, which is part of the literature on barriers to energy efficiency investment and the "energy paradox" (Jaffe and Stavins, 1994), we use the discrete choice method to highlight the role of uncertainty about the quality of renovation work and the price of energy as a barrier to energy efficiency investment. The second chapter provides empirical insight into the role of socio-economic factors, individual preferences for comfort and housing energy performance in explaining residential energy consumption. The third chapter examines the energy performance gap at the dwelling level (actual vs. theoretical energy consumption) and its individual and socio-economic determinants, via quantile regression. Finally, the fourth chapter focuses on the dynamic interactions between energy efficiency and energy consumption by addressing the issue of the direct rebound effect for residential heating use in France.

The 4th cover page states: "Certainly, tax policy is the business of all citizens and deserves their attentive interest. Its consent depends not only on the amount of the tax burden, but also on more psychological factors, referring to the perception of what is legal or legitimate. This issue looks at the different links between taxation and citizenship.
