nown as the export optimismexport pessi mism debate(Bhagwati 1988). The need to collapse the export optimismexport pessimism dualism for a more integrative perspective has been raised by Streeten (1982). Increasingly too, the literature suggests that a mix of both perspectives merits a closer look (. Gereffi 1989). This paper examines the relationship between export growth and economic growth within an integrative framework. It argues that developing countries (abbreviated to LDCs) are rather differentiated in their economic structures so that the relationship between exports and economic growth is likely to vary. Thus, it is unlikely that the above relationship may be fully explained by one viewpoint. Two variables, world demand and petitiveness, capturing demandoriented as well supplyoriented explanations of the mechanisms linking export growth to ine growth are first established. The two variables are then incorporated into an exportsgrowth model, and, their effects on the aforemen tinned relationship investigated. The primary units of analysis are developing countries, although the study is also relevant to regional development. Particularly when developing countries may be conceived as regional units, except that many of the decisions governing economic growth in the former are made at the national level. The paper is organized as follows: the next section documents the theoritical and empirical underpinnings of export optimism as well as export pessimism , and their resulting polarized positions . The model for investigating integration is introduced next, followed by a discussion of the data and results. The paper ends with a summary of the findings and their implications. The Exportsgrowth Debate The question as to whether economic growth may be rapidly promoted through exports is characterized by two schools of thought: Export optimism. Export optimists consider trade to be an engine of growth and place much confidence in the role of prices to allocate resources efficiently. Countries or regions that are able to pete in their exports enhance their economic growth because this increases productivity and specialization, and improves efficiency through better resource allocation. Drawing on the principles of classical parative advantage as well as ventforsurplus and staple theories (see for example Myint 1958。 Kravis 1973。 Riedel 1987). In the second viewpoint, the success of exportled growth is said to rest on a favorable trade environment which depends on the economic prosperity of core regions. This demandoriented viewpoint suggests that exports are not expected to expand faster than the demand for them by core regions (. Lewis 1980。 North 1955。 Dodaro 1993。 Kavoussi 1984。 Syron and Walsh 1968。 Riedel 1988). All these motivated the World Bank (1987。s (1988) study contradicts Balassa39。s petitiveness.
