Inequality and Welfare: Is Europe Special? (Chapter 12)Book chapterAlain Trannoy, In: Economics without Borderss - Economic Research for European Policy Challenges, L. Matyas, R. Blundell, E. Cantillon, B. Chizzolini, M. Ivaldi, W. Leininger, R. Marimon et F. Steen (Eds.), 2017-04, pp. 511-567, Cambridge University Press, 2017

This chapter reviews the literature about inequality and welfare with a particular focus on whether Europe has a special sensitivity to these matters or specific outcomes. It is argued that both statements are likely to be true, which raises the possibility of a causal link. Europe has relatively good results in terms of inequality and welfare in comparison with other continents and more specifically America, because these issues matter for European people. Still, research needs to be fostered in at least 5 areas that are detailed at the end of this review. Specific attention is devoted to the contribution of other social sciences and natural sciences (cognitive science) to the development of our knowledge for the field of inequality and welfare.

Sunspot Fluctuations in Two-Sector Models with Variable Income EffectsBook chapterFrédéric Dufourt, Kazuo Nishimura, Carine Nourry et Alain Venditti, In: Sunspots and Non-Linear Dynamics - Essays in Honor of Jean-Michel Grandmont, K. Nishimura, A. Venditti et N. C. Yannelis (Eds.), 2017, Volume 31, pp. 71-96, Springer-Verlag, 2017

We analyze a version of the Benhabib and Farmer (1996) two-sector model with sector-specific externalities in which we consider a class of utility functions inspired from the one considered in Jaimovich and Rebelo (2009) which is flexible enough to encompass varying degrees of income effect. First, we show that local indeterminacy and sunspot fluctuations occur in 2-sector models under plausible configurations regarding all structural parameters—in particular regarding the intensity of income effects. Second, we prove that there even exist some configurations for which local indeterminacy arises under any degree of income effect. More precisely, for any given size of income effect, we show that there is a non-empty range of values for the Frisch elasticity of labor and the elasticity of intertemporal substitution in consumption such that indeterminacy occurs. This contrasts with the results obtained in one-sector models in both Nishimura et al. (2009), in which it is shown that indeterminacy cannot occur under either GHH and KPR preferences, and in Jaimovich (2008) in which local indeterminacy only arises for intermediary income effects.

The Stabilizing Virtues of Monetary Policy on Endogenous Bubble FluctuationsBook chapterLise Clain-Chamosset-Yvrard et Thomas Seegmuller, In: Sunspots and Non-Linear Dynamics - Essays in Honor of Jean-Michel Grandmont, K. Nishimura, A. Venditti et N. C. Yannelis (Eds.), 2017, Volume 31, pp. 231-257, Springer-Verlag, 2017

We explore the stabilizing role of monetary policy on the existence of endogenous fluctuations when the economy experiences a rational bubble. Considering an overlapping generations model, expectation-driven fluctuations are explained by a portfolio choice between three assets (capital, bonds and money), credit market imperfections and a collateral effect. They occur under a positive bubble on bonds. The key mechanism relies on the existence of gaps between the returns on assets due to financial distortions. Then, we study the stabilizing role of the monetary policy. Such a policy managed by a (standard) Taylor rule has no clear stabilizing virtues.

Exploring the Role of Emotions in Decisions Involving Catastrophic Risks: Lessons from a Double InvestigationBook chapterOlivier Chanel, Graciela Chichilnisky, Sébastien Massoni et Jean-Christophe Vergnaud, In: The Economics of the Global Environment, Graciela Chichilnisky et Armon Rezai (Eds.), 2017, Volume 29, pp. 553-575, Springer, Cham, 2017

Natural disasters due to climate change (like floods, hurricanes, heat waves or droughts) combine a risk of large losses and a low probability of occurrence, requiring decisions to be made in uncertain universes. However, the inability of standard decision under uncertainty models to provide rankings when some outcomes are catastrophic impedes rational (public) decision-making. This paper examines the role of emotions in individuals’ choices among alternatives involving catastrophic events, either in real life (flooding) or artificial (laboratory experiment) situations. We report a survey on 599 respondents aimed at determining how people exposed to different levels of flood risk form beliefs and make decisions under uncertainty before and after emotion-generating events. Data on their emotions, the emotions they expect to experience, their personality and psychological determinants, their symptoms before and after emotion-generating events are collected and analyzed. In parallel with this survey, experimental protocols replicate the emotional experience of a catastrophe and measure its impact on behavior and formation of beliefs. Emotions are induced by framing effects and measured through a self-declared worry scale. We collect behavioral data (insurance choice, subjective beliefs, performance) and measure how they are affected by the emotions felt during the decision-making. These protocols test some assumptions in the survey using experimental paradigms from psychophysics that allow us to control the sources of uncertainty experienced by the subjects. Results confirm that emotions connected with the nature of the risk can significantly affect desire to reduce it. The survey provides valuable material for comparative analysis, revealing how actual experience of an anticipated event affects decisions. The experiments show that emotions affect the decision-making process and the forming of probabilistic beliefs.
