This paper proposes a simultaneous-equation approach to the estimation of the contribution of transport infrastructure accumulation to regional growth. We model explicitly the political-economy process driving infrastructure investments; in doing so, we eliminate a potential source of bias in...

This paper documents a decreasing trend in the geographical concentration of EU agro-food imports. Decomposing the concentration indices into intensive and extensive margins components, we find that the decrease in overall concentration indices results from two diverging trends: the pattern of...

This paper investigates whether the Pesticides Initiative Program has significantly affected the export performance of Senegal's horticulture industry. We apply two main microeconometric techniques, difference-in-difference and matching difference-in-differences to identify the effect of the...

The focus of trade policy has shifted in recent years from economy-wide reductions in tariffs and trade restrictions towards targeted interventions to facilitate trade and promote exports. Most of these latter interventions are based on the new mantra of "aid-for-trade" rather than on hard...

The paper estimates the effect of NAFTA’s rules of origin (ROO) on Mexican access to the US market treating explicitly the endogenous determination of ROOs. The first equation determines Mexico’s NAFTA (preferential) exports to the US as a function of tariff preference and Estevadeordal’s...

The main objective of this paper is to provide estimates of the cost of moving out of subsistence for Madagascar's farmers. The analysis is based on a simple asset-return model of occupational choice. Estimates suggest that the entry (sunk) cost associated with moving out of subsistence can be...

The paper considers the implications of recent changes in the EC relationship with the Central & Eastern European Countries (CEECs) for the EC's traditional links with ACP countries. After reviewing some important aspects of the trade regime implemented by the Lomé Convention, the paper...

Building on earlier work by Estevadeordal, we construct a synthetic index (R-index) intending to capture the restrictiveness on market access due to product specific rules of origin (PSRO) that apply at the tariff-line level. The R-index is constructed for rules of origins under NAFTA and under...

The paper reviews the likely economic effects of the Regional Economic Partnership Agreements (REPAs) proposed by the EU to the ACP countries to succeed to the Lomé IV agreements. We argue that, in spite of some likely positive effects because of reciprocity and because of the North-South...

This Paper provides a new approach to the evaluation of pre-shipment inspection (PSI) programs as ways of improving tariff-revenue collection and reducing fraud when customs administrations are corrupt. We build a model highlighting the contribution of surveillance firms to the generation of...
