DOUENNE Thomas (PSE, Université Paris 1 Panthéon-Sorbonne) : The vertical and horizontal distributive effects of energy taxes : A micro-simulation study of a French policy

This paper proposes a micro-simulation assessment of the distributive effects of the forthcoming increase in the French carbon tax. The policy corresponds to an increase of the carbon price on energies followed by lump-sum transfers targeted to poor households. I evaluate the expected vertical and horizontal distributive effects of the policy and show that the welfare impact on low-income households is ambiguous. If the policy is progressive, it also generates many losers among the poorest. I argue that when households are heterogeneous on multiple dimensions, one can use a fuel poverty indicator to synthesize the tax incidence on the most fragile. Using this criterion, I show that the mechanism proposed should mitigate the increase in fuel poverty but generate losses for almost half of fuel poor households. Thanks to the micro-simulation approach, I then identify the multiple determinants of the heterogeneous tax incidence. Based on these findings, I test alternative revenue-recycling mechanisms. I show that lump-sum transfers indexed on some specific households’ characteristics can potentially soften horizontal distributive effects, both for low-income and fuel poor households. I conclude by discussing the potential acceptability of these mechanisms against other revenue recycling strategies.

HERGHELEGIU Cristina (Paris 1, PSE) : Firm adjustment to customs-driven administrative barriers


This paper analyzes how firms adjust to administrative barriers. Relying on a highly detailed dataset including the universe of Russian transactions over the period 2012-2015, we seek to identify the impact of customs-specific time delays on exports flows. We focus on firm-to-firm trade and show that the time delays induced by customs clearance negatively affect firm-to-firm exports, even after controlling for other potentially confounding factors. We further explore the role of Incoterms used as a tool to delimit the risks between the exporting and importing firms throughout the shipping process. Our results show that export flows are significantly higher when exporters take full control over export clearance.

ZAPECHELNYUK Andrei (University of St Andrews) : A delegation approach to persuasion

We study a monotone persuasion problem. This is a problem of Bayesian persuasion between a principal and an agent, in which the principal’s choice of information disclosure is restricted to monotone partitions. We show that this problem is equivalent to a constrained delegation problem, with the implication that solving one problem also means solving the other. We use this equivalence to apply known techniques in the delegation literature to address the monotone persuasion problem.

HILT Eric : Banks, Insider Connections, and Industrialization in New England : Evidence from the Panic of 1873.

Using newly collected data from Massachusetts, this paper documents the extent of bank director representation non-financial firms’ boards, and investigates whether bank-affiliated companies fared better during the recession that followed the Panic of 1873. Around 59 percent of all non-financial corporations had at least one bank director on their boards. These firms survived the recession of the 1870s at higher rates, and among the surviving firms, those with bank affiliations saw their growth rates and credit ratings decline less than firms without bank affiliations. Consistent with banker-directors helping to resolve problems related to asymmetric information, these effects were strongest among younger firms, and those with lower shares of fixed assets on their balance sheets. In contrast, the presence of bank cashiers on firms’ boards, which created an association with a bank without significantly increasing the likelihood of a credit relationship, had no effect. These results imply that during New England’s industrialization, affiliations with commercial banks helped nonfinancial corporations survive economic downturns

NEBOUT Antoine (INRA) : Hunger Games II : Do Hunger Affects Risk Preferences ?
Co-authors : ASHTON Lydia ; KEMEL Emmanuel

Abstract : Classic economic theory focuses on static and stable preferences. However, there is growing evidence that cognitive, emotional and visceral states (e.g. fatigue, stress or hunger) can mediate behavioral biases and shape preferences (DellaVigna, 2009). In particular, Symmonds & al. (2010) and Levy & al. (2013) provide evidence that risk attitudes fluctuate with metabolic states. In this paper, we follow this stream of research and propose an experimental design with a specific hunger manipulation mechanism using high-protein drink and an original risk attitude elicitation tool that allows parametric estimation of the components of Prospect Theory by using a convex budget line allocation methodology (Choi & al., 2007). The experiment (N=107) took place in the Social Sciences Experimental Lab (Xlab) at the University of California, Berkeley. Fasting requirement combined with the nutritional-shake tasting activity resulted in a successful manipulation of hunger. Our preliminary results suggest a limited impact of hunger on the utility function and loss aversion parameters. There could be a positive effect of hunger on the level of optimism (represented by the elevation of the probability weighting function) suggesting a lower risk aversion for hungry (fasting) individuals for small gain probabilities. These results have to be confirmed by further analysis.

MARINESCU Ioana (University of Pennsylvania) : Labor market concentration
Co-authors : AZAR Jose ; STEINBAUM Marshall

A product market is concentrated when a few firms dominate the market. Similarly, a labor market is concentrated when a few firms dominate hiring in the market. Using data from the leading employment website CareerBuilder, we calculate labor market concentration for over 8,000 geographic-occupational labor markets in the US. Based on the DOJ-FTC horizontal merger guidelines, the average market is highly concentrated. Using a panel IV regression, we show that going from the 25th percentile to the 75th percentile in concentration is associated with a 17% decline in posted wages, suggesting that concentration increases labor market power.

PRADELSKI Bary (ETH Zurich) : Title : Micro influence and macro dynamics of opinion formation
Co-authors : Bernhard Clemm von Hohenberg and Michael Maes

Session organisée par Francis Bloch (Paris 1/PSE) Abstract : Social media platforms, comment boards, and online market places have created unprecedented potential for social influence and resulting opinion dynamics such as polarization. We propose an encompassing model that captures competing micro-level theories of social influence. Conducting an online lab-in-the-field experiment, we observe that individual opinions shift linearly towards the mean of others’ opinions. From this finding, we predict the macro-level opinion dynamics resulting from social influence. We test our predictions using data from another lab-in-the-field experiment and find that opinion polarization decreases in the presence of social influence. We corroborate these findings with large-scale field data.
