Spatial Price Linkages and Imperfect Competition in Regional Cattle Markets

This paper analyzes non-competitive market conduct in the U.S. cattle procurement markets. Rather than relying on estimation of conduct parameters or measures of market concentration the analysis is based on the dynamics of price adjustment across regional markets. A VAR model is estimated using a multiple co-integration technique as a test for spatial market integration. The results are then related with hypotheses about pricing conduct in spatial markets.

An updated look at the recovery of agricultural productivity in Sub-Saharan Africa:

"We analyze the evolution of Sub-Saharan Africa's agricultural total factor productivity (TFP) over the past 40 years, looking for evidence of recent changes in growth patterns using a nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan Africa's agriculture during the 1984–2003 period after a long period of poor performance and decline. That recovery is the consequence of improved efficiency in production resulting from changes in the output structure and an adjustment in the use of inputs, including an overall net reduction in fertilizer use but increased fertilizer use in most of the best-performing countries. Policy changes African countries conducted between the mid-1980s and the second half of the 1990s together with technological innovations available at that time appear to have played an important role in improving agriculture's performance. As TFP growth in Sub-Saharan Africa is mainly a result of catching up to the frontier, we expect growth to slow in the coming years unless African countries accelerate the incorporation of innovations into the production process and increase the speed of technical change." from authors' abstractAgriculture, Efficiency, Malmquist index, Total factor productivity, Technical change, Development strategies,

How important is a regional free trade area for Southern Africa?: Potential impacts and structural constraints

"We develop a detailed trade analysis to assess the potential welfare impacts of a free trade agreement (FTA) on the agricultural sector of southern African countries and to determine opportunities and challenges faced by the region as a consequence of the agreement. Our approach combines an in-depth look at the current trading patterns of southern African countries with the application of a partial equilibrium analysis that uses bilateral trade data at the four-digit standard international trade classification (SITC) level for 193 agricultural industries in 14 southern African countries. Low diversification of agricultural exports in most southern African countries seems to be a major constraint for promoting regional trade. In most countries, overall welfare effects of an FTA would be positive but small. Inefficient agricultural producers with a regional comparative advantage for agriculture would benefit from trade creation with the rest of the world. Welfare results for regional importers would be negative because of increased imports from inefficient regional producers. These results suggest that the region should be looking at regional policies and interventions beyond trade arrangements, such as those targeting investment, agricultural productivity, and diversification, to enhance benefits of regional trade liberalization." from authors' abstractRegional trade agreement, Agricultural trade, Development strategies,

Lagging regions and development strategies: The case of Peru

"Despite the economic transformation of Peru's coastal economy, the country's inland region remains poor and underdeveloped. We herein examine the economic linkages between the two regions using a multi-regional computable general equilibrium model based on a regionalized social accounting matrix. The model results show that coastal growth undermines the inland economy by increasing import competition and internal migration. Peru, therefore, cannot rely solely on rapid national growth to generate broad-based poverty reduction. When we simulate policies aimed at curbing divergence, we find that reducing interregional transaction costs stimulates national economic growth, but widens divergence by shifting inland production towards agriculture and concentrating investment in coastal manufacturing. In contrast, conditional cash transfers reduce regional and rural-urban inequality, but do not stimulate national growth. Finally, investing in inland productivity (through extension services and improved rural roads) reduces regional divergence, but the resulting market constraints worsen rural-urban inequality. These findings suggest that isolated interventions may worsen inequality, and that complementarities exist between supply-side investments and policies aimed at stimulating demand and improving access to national markets." from authors' abstractRegional development, Public investments, economic growth, Development strategies,
