This empirical investigation aims at exploring the determinants of money demand in Vietnam by using both linear and nonlinear autoregressive distributed lag models over the period spanning from the third quarter of 2000 to the first quarter of 2018. Our findings can be summarized as follows: firstly, when the shock is symmetric (i.e. a permanent nominal appreciation of 1%), the money demand increases by 3.7% in the long term. Secondly, when the shock is asymmetric, for a permanent nominal appreciation of 1%, we observe an increase of 15.6% in the money demand. Whereas, for a permanent nominal depreciation of 1%, we observe a decrease of 7.4% in the money demand. These results are consistent with symmetry tests and lead us to think that asymmetries occur mainly in the short run and are transmitted to the long run.

From the onset of the euro crisis to the Brexit vote, we have witnessed impressive reductions of current account imbalances in peripheral countries of the euro area. These reductions can be the result of either a compression of internal demand or an improvement in external competitiveness. In this paper, we compute exchange rate misalignments within the euro area to assess whether peripheral countries have managed to improve their external competitiveness. After controlling for the reduction of business cycle synchronization within the EMU, we find that peripheral countries have managed to reduce their exchange rate misalignments thanks to internal devaluations. To some extent, these favorable evolutions reflect improvements in external competitiveness. Nevertheless, these gains could only be temporary if peripheral countries do not improve their non-price competitiveness, their trade structures and their international specializations in the long run.

The reduction of global imbalances observed during the climax of crisis is incomplete. In this context, currencies realignments are still proposed to ensure global macroeconomic stability. These realignments are based on equilibrium rates derived from equilibrium exchange rate models. Among these models, we have the fundamental equilibrium exchange rate model introduced by Williamson (1994). This approach is often labelled as normative, mainly because the equilibrium is not uniquely determined. If the FEER is not related either in the short or in the long to the real exchange rates, we see no clear justification to intervene in foreign exchange markets based on these equilibrium rates. In this case, the FEER does not include any element of long run predictive value and should not be used to reduce global imbalances. This paper provides panel empirical evidences that the FEER is related to real exchange rate in the long run and thus could be a useful tool to prevent the resurgence of large global imbalances and associated risks.

We investigate whether financial openness has played a major role in the evolution of global imbalances over the period before the crisis of 2008. We estimate, with panel regression techniques, the impact of financial openness on medium run trends in current account imbalances for industrialized and emerging countries by using a de jure measure of financial openness and a de facto measure of financial openness. Nowadays, current account imbalances are larger in reason of higher capital mobility. Nevertheless, a large part of imbalances may be considered as unrelated with the evolution of macroeconomic fundamentals.

This paper investigates the temporal links between two models of equilibrium exchange rate, namely the behavioral and the fundamental approaches. Our results show that, even though in the long-run they are closely related, important differences are observed for some countries and/or some periods. Contrary to previous contributions, we analyze the factors that explain this disconnection. We outline structural changes in matter of competitiveness, the dynamics of foreign assets and valuation effects as explanations. This novel evidence is important if the two approaches for assessing misalignments are used for policy decisions such as setting tariffs to cope with the “currency war”.
