provides economic analysis and policy advice with the aim of promoting sustainable and equitable development. The Institute began operations in 1985 in Helsinki, Finland, as the first research and training centre of the United Nations University. Today it is a unique blend of think tank, research institute, and UN agency-providing a range of services from policy advice to governments as well as freely available original research. The Institute is funded through income from an endowment fund with additional contributions to its work programme from Finland, Sweden, and the United Kingdom as well as earmarked contributions for specific projects from a variety of donors.

In this article, we analyse the learning-by-exporting (LBE) hypothesis in the Mozambican context. Due to the presence of the 'Born-Global' phenomenon among exporters, we address the endogeneity introduced by self-selection, combining a generalised Blinder-Oaxaca approach with results from traditional matching techniques. Our results show that very few manufacturing firms export, and that export participation is highly persistent. There is also evidence supporting the LBE hypothesis and the results suggest a significant export premium of between 17 and 21%, controlling for differences in observable characteristics between exporters and nonexporters. Finally, qualitative information on non-exporters seeking new markets suggests that 'lack of knowledge of potential markets' is the most severe constraint to international market entry. We conclude that the Mozambican Export Promotion Institute (IPEX) could play an important role in overcoming this information deficit for potential Mozambican exporters.

UNU-WIDER gratefully acknowledges the financial contributions to the research programme from the governments of Denmark, Finland, Sweden, and the United Kingdom. The World Institute for Development Economics Research (WIDER) was established by the United Nations University (UNU) as its first research and training centre and started work in Helsinki, Finland in 1985. The Institute undertakes applied research and policy analysis on structural changes affecting the developing and transitional economies, provides a forum for the advocacy of policies leading to robust, equitable and environmentally sustainable growth, and promotes capacity strengthening and training in the field of economic, and social policy-making. Work is carried out by staff researchers and visiting scholars in Helsinki and through networks of collaborating scholars and institutions around the world.
