On the Political Economy of Sequential Reforms

This paper proposes an explanation for why efficient reforms are not carried out when losers have the power to block their implementation, even though compensating them is feasible. We construct a signaling model with two-sided incomplete information in which a government faces the task of sequentially implementing two reforms by bargaining with interest groups. The organization of interest groups is endogenous. Compensations are distortionary and government types differ in the concern about distortions. We show that, when compensations are allowed to be informative about the government’s type, there is a bias against the payment of compensations and the implementation of reforms. This is because paying high compensations today provides incentives for some interest groups to organize and oppose subsequent reforms with the only purpose of receiving a transfer. By paying lower compensations, governments attempt to prevent such interest groups from organizing. However, this comes at the cost of reforms being blocked by interest groups with relatively high losses.

Statistical Inference for Computable General Equilibrium Models with Application to a Model of the Moroccan Economy

We study the problem of measuring the uncertainty of CGE (or RBC)-type model simulations associated with parameter uncertainty. We describe two approaches for building confidence sets on model endogenous variables. The first one uses a standard Wald-type statistic. The second approach assumes that a confidence set (sampling or Bayesian) is available for the free parameters, from which confidence sets are derived by a projection technique. The latter has two advantages: first, confidence set validity is not affected by model nonlinearities; second, we can easily build simultaneous confidence intervals for an unlimited number of variables. We study conditions under which these confidence sets take the form of intervals and show they can be implemented using standard methods for solving CGE models. We present an application to a CGE model of the Moroccan economy to study the effects of policy-induced increases of transfers from Moroccan expatriates.

Leadership ethics and the problem of Dirty Hands in the political economy of contemporary Africa

Cet article discute des problèmes de gouvernance et de corruption en Afrique dans le cadre d’un débat politique et philosophique large entre universalisme et relativisme, idéalisme et réalisme, ainsi que entre individualisme et communautarisme. Premièrement, je défends que l’approche réaliste de l’éthique politique et du leadership ne permet pas de différencier entre les éléments descriptifs et prescriptifs de la gouvernance et peut aisément être utilisée pour justifier « les Mains Sales » des dirigeants au nom de l’intérêt supérieur de la nation, même dans les cas où l’intérêt personnel est la seule force motivationnelle pour les actions qui sapent les codes sociaux et éthiques ordinaires. Deuxièmement, l’article montre la faillite de la confiance publique dans le gouvernement et la faiblesse de l’Etat renforce les politiques communautariennes sub-nationales qui tendent à être fondées sur l’ethnie et exclusive, et par conséquent, qui viole le cœur de l’éthique publique, c’est-à-dire l’impartialité. Finalement, l’article suggère que les principes d’éthique universels pour les services publiques soient introduits en complément plutôt qu’en concurrence avec les éthiques locales, socialement et culturellement limitée au privé. Cela requière, d’une part, que nous comprenions mieux la complexité historique, les circonstances économiques et sociales et les arrangements politiques transitionnels dans les pays africains. D’autre part, un nous devons investir dans une éducation éthique civique et professionnel réflexive qui adopte un point de vue nuancé entre le réalisme politique et l’idéalisme comme point de départ des réformes institutionnelles, aussi bien que modalité de changement des comportements à long terme.

Punishing Local Incumbents for the Local Economy

After decennia of research on economic voting, it is now established that the state of the economy affects voting behaviour. Nevertheless, this conclusion is the result of a focus on predominantly national-level economies and national-level elections. In this paper, we show that at a local level as well, mechanisms of accountability linked to the economy are at work. The local economic context affected voting behaviour in the 2012 Belgian municipal elections, with a stronger increase of unemployment rates in their municipality significantly decreasing the probability that voters choose an incumbent party. Additionally, we observe that voters are not opportunistically voting for incumbents who lower tax rates. Instead, voters seem to be holding local incumbents accountable for local economic conditions. We hence conclude that voters care about economic outcomes, not about what specific policies are implemented to reach these outcomes.
