Most CGE trade models fix current account balances exogenously, in accordance with the widely accepted view that trade policy may influence trade flows, but that current accounts are constrained by symmetric capital account balances, on which trade policy has little effect. The MIRAGE-D model...

English Abstract: In balancing international financial data (Lane and Milesi-Ferretti, 2006), contrary to most matrix adjustment problems, the only constraints are that, for any given category of assets and liabilities, the sum of assets over countries must equal the sum of liabilities....

In the vast majority of recursive dynamic CGE models, the savings rate is constant and exogenous. Intertemporal CGE models, by contrast, are solved simultaneously for all periods, and agents optimize intertemporally. But the theoretical consistency of intertemporal optimization is achieved only...

This note briefly presents the GAMS matrix adjustment program GPCEMA.gms (GPCEMA stands for General Purpose Cross-Entropy Matrix Adjustment). The matrix adjustment problem tackled in GPCEMA.gms is to adjust an existing matrix (called the prior matrix) so that the adjusted matrix (the posterior...

In this paper, we report on an experimental application of Kullback-Leibler cross-entropy minimization to estimate trade flows between regions. Interregional trade flows were estimated for 31 categories of goods and services, between three regions of the Province of Quebec in 1992: the Montreal...

In this paper, we present a minimalist version of a model of bond financing and debt, imbedded in a stepwise dynamic CGE model. The proposed specification takes into account the main characteristics of bond financing. Bonds compete on the securities market with shares, so that the yield demanded...

This paper deals with closure issues that arise in the context of global multinational models, typically, trade models. We also explore a few related issues: model homogeneity, the role of exchange rates, calibration consistency, and testing for calibration consistency and model homogeneity. To...
