Trade Market

This paper studies the impact on the eggplant world market caused by NAFTA, TLCUEM and by the integration of China into the WTO. The impacts were measured as changes on commercial flows and prices. A spatial equilibrium model with endogenous prices was specified and estimated from which alternative scenarios were considered: with and without the operation of these treaties and the incorporation of China into the WTO. The results show that the operation of these treaties results in trade diversion. Furthermore, under the integration of China into the WTO, even under free world trade market there is no impact on the eggplant world market.

Key words: Cucumber world market, international trade, economic integration, quadratic programming, spatial equilibrium models.Abstract. This study empirically analyzed the potential effects of the complete operation of North American Free Trade Agreement (NAFTA), European Union and Mexico Free Trade Agreement (EUMFTA), and the integration of China to the World Trade Organization (WTO), on the cucumber world market. Special emphasis on the impact on Mexico was presented, from a worldwide perspective. A spatial equilibrium model with endogenous prices was constructed for this purpose. Among the findings are: (1) Mexican producers benefited from the complete implementation of NAFTA and EUMFTA. (2) The incorporation of China as a member of the WTO showed a negligible effect on the commercial flows and prices in the cucumber world market. (3) Mexican cucumber production is highly competitive, in the world market, because it has the lowest supply costs.Palabras Clave: Mercado mundial del pepino, integración económica, comercio internacional, programación cuadrática, modelos de equilibro espacial.Resumen. Este estudio analiza empíricamente los efectos potenciales de la operación completa del Tratado de Libre Comercio de América del Norte (TLCAN), Tratado de Libre Comercio de la Unión Europea y México (UMFTA), y la integración de China a la Organización Mundial de Comercio (OMC) en relación al mercado mundial del pepino. Se presentan, con énfasis especial, los impactos sobre México desde una perspectiva mundial.

Quantitative Evaluations

Abstract A key input to quantitative evaluations of transport infrastructure projects is their impact on transport costs. We propose a new method of estimating this impact relying on widely accessible customs data: by using the route choice of exporters. We combine our method with a spatial equilibrium model to study the effects of the massive expressway construction in China between 1999 and 2010. We find transport costs are 20% lower on expressways than on regular roads. The expressways construction increases aggregate exports by 10% and domestic trade by 14%. It generates 5.1% welfare gains, implying a 150% net return to investment.

Validation Strategy

Robust calibration and validation of applied urban models are prerequisites for their successful, policy-cogent use. This is particularly important today when expert assessment is questioned and closely scrutinized. This paper proposes a new model calibration-validation strategy based on a spatial equilibrium model that incorporates multiple time horizons, such that the predictive capabilities of the model can be empirically tested. The model is implemented for the Greater Beijing city region and the model validation strategy is demonstrated over the Census years 2000 to 2010. Through forward/backward forecasting, the model validation helps to verify the stability of the model parameters as well as the predictive capabilities of the recursive equilibrium framework. The proposed modelling strategy sets a new standard for verifying and validating recursive equilibrium models. We also consider the wider implications of the approach.

The City

A spatial-equilibrium model of a local public economy is developed in four settings. Each setting is distinguished by two factors: whether the city is ‘open’ or ‘closed’, and the method used to determine the urban fringe. The four settings are contrasted by use of a numerical illustration.
