Why Developing Countries Have Failed to Increase Their Exports of Agricultural Processed Products

The article uses the case study of coffee, tea and cocoa to analyse whether tariff escalation constitutes a barrier to market access that thwarts diversification efforts of developing countries into exports of value‐added agricultural processed products. It also examines the extent to which non‐tariff barriers act as market access barriers that constrain developing countries from developing their exports of agricultural processed products. Our analysis shows that tariff escalation is not the main barrier; rather it is the prevalence of non‐tariff barriers (including domestic non‐tariff barriers) that limits the ability of developing countries to increase their agricultural processed exports. This has important policy implications in terms of the emphasis that trade negotiators and policy planners should place on addressing non‐tariff barriers.     

Social Capital,Investment and Economic Growth: Some Evidence for Spanish Provinces

Abstract

This article analyses the impact of social capital on regional economic growth in Spain during the 1985–2005 period. The literature in this context is virtually nonexistent and, in addition, whereas most studies, regardless of their context, have used survey data in order to measure social capital, we use a measure whose construction is based on similar criteria to other measures of capital stock. Compared with more standard measures of social capital and trust, our measure is available with a high level of disaggregation, and with annual frequency for a long time period. Following a panel data approach, our findings indicate that social capital has a positive impact on GDP per capita growth in the context of Spanish provinces, implying that ‘social features’ are important for explaining the differences in wealth that one might find across Spanish provinces. We also explore the transmission mechanisms from social capital to growth, finding a highly positive relation between social capital and private physical investment.
