Estimates of the elasticity of substitution between domestic and foreign varieties are small in macroeconomic data, and substantially larger in disaggregated studies. This may be an artifact of heterogeneity. We use disaggregated multilateral trade data to structurally identify elasticities of...

We show that an American monetary shock wields an influence, though limited, over the Lebanese output in accordance with the literature advances. However, as we are waiting for a stronger transmission of U.S. short-term rates to Lebanese short-term rates, we notice that this transmission is weak...

The paper investigates if the most popular alternative to the purchasing parity power approach (PPP) to estimate equilibrium exchange rates, the fundamental equilibrium exchange rate (FEER) influences exchange rate dynamics in the long run. For a large panel of industrialized and emerging...

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...

This paper investigates the impact of a real current account adjustment on terms of trade, aggregate productivity and welfare-based exchange rate in a two-country general equilibrium model. As in Melitz (2003), firms are heterogeneous in productivity and endogenously enter and exit their...

This paper shows that official statistics substantially underestimate the net foreign asset positions of rich countries because they fail to capture most of the assets held by households in offshore tax havens. Drawing on systematic anomalies in portfolio investment positions and a unique Swiss...

This paper studies the impact of the main external shocks which the eurozone and member states have undergone since the start of the 2000s. Such shocks have been monetary (drop in global interest rates), financial (two stock market crises) and real (rising oil prices and an accumulation of...

We analyze, in a unified theoretical framework, the two main models for equilibrium exchange rate, namely, the BEER and the FEER approaches. In order to understand the interactions between them, we study in detail the temporal links between these two measures. Our results show that, in average,...

The model presented in this paper has two objectives. First, it models global imbalances in a simple way while conserving real and financial approaches. This double approach is necessary because Global Imbalances are due to the conjunction of financial and real phenomena: the increase in the...

We investigate if capital account openness has played a major role in the evolution of global imbalances on the period 1980-2003. We estimate, with panel regression techniques, the impact of capital account openness on medium run current account imbalances for industrialized and emerging...
