Efficiency of financial markets is one of the most studied subjects in theoretical finance. Formalization of this idea is realised by the random walk model. Numerous tests have been developed to validate the hypothesis of identically and independently distributed innovations. But the results of...

In order to assess the growth implications of policy complementarities, this paper applies second-best results to reform indicators. During the transition from central planning to EU integration, which corresponds to a policy cycle, a complementarity index based on structural indicators compiled...

This paper studies the determinants of poverty dynamics in several rural areas from Madagascar. A particular attention is devoted to testing if rural poverty persistence in Madagascar could be explained by a vicious circle leading to a poverty trap. Annual poverty transitions retrieved from an...

This paper investigates empirically how three types of socio-political instability—elite, violent, and social—influence international aid allocation by donors. The results indicate that aid allocation depends on the type of instability (the effect of violent and elite instability is...

This thesis proposes to determine the effect of the Health insurance reform in Tunisia on pharmaceutical demand and supply. For this purpose, we present the main characteristics of the Tunisian pharmaceutical market, with describing the objectives and modalities of implementation of Health...

Hospital heterogeneity is a major issue in defining a reimbursement system. If hospitals are heterogeneous, it is difficult to distinguish which part of the differences in costs is due to cost containment efforts and which part cannot be reduced, because it is due to other unobserved sources of...

In this paper, we implement Granger causalty tests using panel data as methodology perfected by Hurlin (2004, 2005) and Hurlin and Venet(2004). We consider the bilateral trade patterns of the European Union with 17 countries over the period 1976-2000. We show that for the whole sample, there are...

This article analyses an individual microcredit program developed in Rio’s shantytowns. We study its selection criteria and the determinants of borrowers’ repayment performance. More specifically, this work aims to study the link between informality and credit discipline. First, we question...

Using panel data from Argentina during the 1990’s, this paper concludes that, in Argentina, income ‘mobiles’ did change over time. Among the household variables with a structural relation with income dynamics, we find university education, protecting from income declines though not...

We empirically investigate the impact of option listing on the underlying stock efficiency by looking at the volume-volatility relation of underlying stock. We use a time- consistent bivariate VAR (Vector Autoregressive Regression) model that includes time duration between trades. This model...
