Étude de l'efficacité de la dévaluation du franc CFA au Bénin

This paper examines the effectiveness of CFA franc devaluation in Benin. Our results show that the nominal devaluation generate a real exchange depreciation, thanks to strict anti-inflation measures implemented

Termes de l'échange endogènes et cycles économiques réels : une application à la Côte-d'Ivoire

À l’aide d’un modèle de cycles réels, la présente étude vise à expliquer, de façon endogène, les fluctuations des termes de l’échange en Côte-d’Ivoire. Pour ce faire, nous cherchons principalement à répondre aux deux questions suivantes : les chocs d’offre et de demande sur le marché d’exportation suffisent-ils à expliquer les variations des termes de l’échange? Et quelle est leur importance relative dans la dynamique des termes de l’échange? Les résultats montrent que les deux chocs considérés expliquent bien la volatilité des termes de l’échange. Nous avons noté que ces deux sources d’impulsions ont un impact significatif sur les fluctuations économiques en Côte-d’Ivoire.We build a real business cycle model of a semi-small open economy to study endogenously the movements in terms of trade in the Ivory Coast. The main goal of this paper is to answer two key questions : Can domestic supply and foreign demand shocks account for fluctuations in terms of trade? What is the relative importance of supply versus foreign demand shocks in terms of trade dynamics? Our results suggest that both disturbances are necessary to explain terms of trade fluctuations. We also find that both types of disturbances have a significant impact on economic fluctuations in the Ivory Coast. Key words : real business cycles, terms of trade shocks, stochastic general equilibriu

Sovereign debt markets in light of the shadow economy

We investigate the controversial role of the informal sector in the economy of 64 countries between 2003 and 2007 by focusing for the first time on the impact it has on sovereign debt markets. In addition to a standard ordered probit regression, we employ two nonparametric neural network modeling techniques in order to capture possible complex interactions between our variables. Results confirm our main hypothesis that the informal sector has significant adverse effects on credit ratings and lending costs. MLP neural networks offer the best fit to the data, followed by the RBF neural networks and probit regression, respectively. The results do not change with respect to the stage of economic development of a country and contradict views about the possibility of significant economic benefits arising from the informal sector. Our study has important implications, especially in the context of the ongoing sovereign debt crisis, since it suggests that a reduction in the informal sector of financially challenged countries is likely to help in relaxing credit risk concerns and cutting down lending costs. Finally, a decision tree analysis is used to exploit the inherent discreteness in the data and derive intuitive rules with respect to the level of the informal sector

The Coevolution of Finance and Property Rights: Evidence from Transition Economies

The transition from communism to capitalism was necessarily accompanied by a sudden and abrupt increase in the financialization of society. This increase occurred in an environment that, even now, still has little experience with or expertise in financialization. Given that financialization occurred simultaneously with the growth and evolution of other political and economic institutions, the question arises: What was the effect on these other nascent institutions like property rights? This article empirically analyzes the relationship between financialization and property rights in transition countries. Using a unique monthly database of twenty transition countries over a period from 1989 to 2012, this article finds that the influence of financialization depends on which definition of “financialization” is used. In particular, increases in basic financial intermediation improved property rights. However, higher-order “financialization,” proxied here by the size of capital markets and the wages in the financial sector, appeared to have a negative impact on the development of broad-based property rights in transition

Fiscal policy and asset prices

We assess the role played by scal policy in explaining the dynamics of asset markets. Using a panel of ten industrialized countries, we show that a positive scal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the e¤ect of scal policy is temporary, housing prices gradually and persistently fall. As a result, the attempts of scal policy to mitigate stock price developments may severely de-stabilize housing markets. The empirical ndings also point to: (i) a contractionary e¤ect of scal policy on output in line with the existence of crowding-out e¤ects; (ii) a weakening of the e¤ectiveness of scal policy in recent times; (iii) signi cant scal multiplier e¤ects in the context of severe housing busts; and (iv) an increase of the sensitivity of asset prices to scal policy shocks following the process of nancial deregulation and mortgage liberalization. Finally, the evidence suggests that changes in equity prices may help governments towards consolidation of public nances.COMPETE; QREN; UE Fundo Europeu de Desenvolvimento Regional; Fundação para a Ciência e a Tecnologia (FCT

Procyclicality or Reverse Causality?

There is a large literature showing that fiscal policy is either acyclical or countercyclical in industrial countries and procyclical in developing countries. Most of this literature is based on OLS regressions that focus on the correlation between a fiscal variable (usually the budget balance or expenditure growth) and either GDP growth or some measure of the output gap. This paper argues that such a methodology does not permit the identification of the effect of the business cycle on fiscal policy and hence cannot be used to estimate policy reaction functions. The paper proposes a new instrument for GDP growth and shows that, once GDP growth is properly instrumented, procyclicality tends to disappear

The impact of institutional volatility on financial volatility in transition economies

What have been the determinants of financial volatility in the transition countries of Central and Eastern Europe and the former Soviet Union? This paper posits that institutional changes, and in particular the volatility of crucial institutions such as property rights, have been the major causes of financial volatility in transition. Building a unique monthly database of 20 transition economies from 1991 to 2017, this paper applies the GARCH family of models to examine financial volatility as a function of institutional volatility. The results show that more advanced institutions help to dampen financial sector volatility, while institutional volatility feeds through directly to financial sector volatility in transition. Democratic changes in particular engender much higher levels of volatility, while property rights are sensitive to the metric used for their measurement
