A global ocean biogeochemical model is used to quantify the sensitivity of marine biogeochemistry and air–sea CO2 exchange to variations in dust deposition over decadal timescales. Estimates of dust deposition generated under four climate states provide a large range in total deposition with spatially realistic patterns; transient ocean model experiments are conducted by applying a step-functio...

Sustainability in the supply chain means pushing the supply chain to focus on social, economic and environmental aspects, and addressing the existing problems in the traditional supply chain. Considering the importance of evaluating supply chain networks, especially in the field of perishable commodities, this paper aimed to design a mathematical model for the reverse supply chain of perishable...

Empirical studies of international trade have concentrated on singleequation models to analyse the demand relationship for imports and exports [Houthakker and Magee (1969). Naqvi et al (1983), Bnhmani-Oskooee (1984,1986)]. These studies have assumed that the imports and exports price elasticities facing any individual country are infinite or at least large. The assumption of infinite supply pri...

regarding the importance and high proportion of iranian manufacturing industries' export in nonoil export basket, and their impact on economic growth, it is essential that effective factors on the manufacturing industries' export be investigated. this paper investigates the impact of human capital on the export of iranian industries, using a panel data set of 2-digit isic manufacturing industri...

Tanzania is among the many African countries that have engaged in agricultural liberalisation since the mid-1980s, in the hope that reforms which introduce price incentives and efficient marketing will encourage producers to respond. This paper assesses that claim by examining the supply response of agricultural output in Tanzania. Our estimates suggest that agricultural supply response is quit...

In this paper we use micro data on both trade and production for a sample of large Chinese manufacturing firms in the footwear industry from 2002-2006 to estimate an empirical model of export demand, pricing, and market participation by destination market. We use the model to construct indexes of firm-level demand, cost, and export market profitability. The empirical results indicate substantia...

World-wide cross-country regressions are used to examine South Asia’ s export structure through the lens of Heckscher± Ohlin trade theory. By comparison with other regions, South Asia’s exports are unusually concentrated on labour-intensive manufactures. This distinctive export structure is shown to be the result mainly of South Asia’s distinctive combination of resources: by comparison with ot...

This paper elucidates the impacts of the September 2005 foot and mouth disease outbreak on the Brazilian meat market for different levels of the industry (export, wholesale, and farm). The associated import ban by Russia on Brazilian meat exports is also analyzed. Results suggest that the increase in domestic supply due to the import ban generated downward pressure on prices at all levels for p...
