This work was aimed at analysing the effects of the sudden food price explosion followed by pricecrash which occurred recently on the foreign trade of the food economy. Comparison of the balances of thedifferent countries was difficult due to the differences in the absolute dimensions; therefore...

Self management of natural resources has started to gain increasing attention as an alternative tool to command-and-control and market-based tools, but the fundamental question remains: is self management economically beneficial such that it should be promoted in the first place? This article...

This paper aims to provide a flexible methodological framework to estimate import demandmodels, which explicitly considers the stochastic properties of data and the endogenous/exogenousnature of some variables. The French imports of virgin olive oil have been used as a case study withSpain,...

A spatial price equilibrium (SPE) model of the world sugar market is programmed. The model coversmore than hundred regions and contains sugar in as a sole product. It has a detailed coverage ofpolicies and bilateral trade agreements. It is programmed as a mixed complementarity problem(MCP) in...

A simple but new theoretical approach is used to analyse ex-ante the impact of tariff reduction. Thismethodology is based on the assumption of a constant price relation between each direct substitutableproduct. No elasticities are needed, but accurate import and domestic prices of the most...

In this paper, the welfare results in trade liberalisation scenarios in global CGE models (like GTAP)are analysed. The default modeling strategy in trade is the Armington assumption with bilateral tradeflows in industries. The negative terms of trade effects that often dominate the negative...

Seafood consumption in the U.S. has increased over the period 1990 to 2003. A large percentage of the seafood consumed in the U.S. is imported. The most important seafood products imported to the U.S. are shrimp, Atlantic salmon, tilapia, catfish, crayfish, mussels and a mixture of mollusks. In...

This paper illustrates the opportunities of incorporating more advanced functional forms into multi-country trade policy models. It suggests the use of flexible forms such as the Symmetric Generalized McFadden Function (SGMF) or the Normalized Quadratic-Quadratic Expenditure System (NQQES)....

Computable General Equilibrium (CGE) models have been widely used for quantitative analysis of global economic issues. However, CGE models are frequently criticized for resting on weak empirical foundations. This paper builds on recent work in macro-econometric estimation, developing an approach...

The threshold autoregressive (TAR) model by Enders and Granger (1998) and Enders and Siklos (2001) is a popular econometric model that estimates asymmetric price transmission (APT) with non-stationary time series data. However, empirical studies have not considered much the arbitrariness of...
