Recent evidence has renewed views on the size of fiscal multipliers. It is notably emphasized that fiscal multipliers are higher in times of crisis. Starting from this literature, we develop a simple and tractable model to deal with the fiscal strategy led by euro area countries. Constrained by...

We provide several characterizations of unanimity decision rules, in a public choice model where preferences are constrained by attributes possessed by the alternatives (Nehring and Puppe, 2007a,b). Solidarity conditions require that when some parameters of the economy change, the agents whose...

Maximum-likelihood estimation of nonlinear models with fixed effects is subject to the incidental-parameter problem. This typically implies that point estimates suffer from large bias and confidence intervals have poor coverage. This paper presents a jackknife method to reduce this bias and to...

We investigate the links between capital cities, conict, and the quality of governance, starting from the assumption that incumbent elites are constrained by the threat of insurrection, and that this threat is rendered less e_ective by distance from the seat of political power. We develop a...

The renewal of interest in macroeconomic theories of search frictions in the goods market requires a deeper understanding of the cyclical properties of the intensive margins in this market. We review the theoretical mechanisms that promote either procyclical or countercyclical movements in time...

We introduce a “nestedness” relation for a general class of sender-receiver games and compare equilibrium properties, in particular the amount of information transmitted, across games that are nested. Roughly, game is nested in game if the players’s optimal actions are closer in game. We...

Ce n’est pas la même chose d’interroger les Français sur l’immigration ou la peine de mort par internet ou par téléphone. L’enquête post-électorale de la présidentielle 2012 du CEVIPOF permet de s’en rendre compte puisque les deux modes d’interrogation ont été utilisés sur...

This paper aims at investigating first the (possibly time-varying) empirical relationship between the level and conditional variances of price and financial stability, and second, the effects of macro and policy variables on this relationship in the United States and the Eurozone. Three...

We build an agent-based model to study how the interplay between low- and high frequency trading affects asset price dynamics. Our main goal is to investigate whether high-frequency trading exacerbates market volatility and generates flash crashes. In the model, low-frequency agents adopt...

Assuming that private agents need to learn inflation dynamics to form their inflation expectations and that they believe a hybrid New-Keynesian Phillips Curve (NKPC) is the true data generating process of inflation, we aim at establishing the role of forward-looking information in inflation...
