A Bayesian Total Factor Productivity Analysis of Tropical Agricultural Systems in Central-Western Africa And South-East Asia AgEcon
Tonini, Axel; Matus, Silvia Saravia; Gomez y Paloma, Sergio.
This paper computes and analyses total factor productivity (TFP) growth rates for tropical agricultural systems in Central-Western Africa and South-East Asia. Two regions that despite sharing common agro-ecological conditions, have pursued different adoption rates of green revolution technology and have reported dissimilar yields per hectare. A panel data set is constructed for the period 1987-2007 from the FAOSTAT database. A Bayesian stochastic frontier model with country specific temporal variation in technical efficiency is estimated. Technical efficiency estimates reveal that there is substantial room for improvement in both continental sub-sets and that TFP estimates show on average larger rates of growth for South-East Asian countries as compared to...

Over fifteen years have elapsed since the transition from the centrally planned economic system started in the early 1990’s. During this time agricultural and rural areas of Central and Eastern Europe have undergone profound structural changes with wide variations in the degree of transformation and in the rate of success in creating a competitive market and private ownership based food and agricultural system. By becoming member of the European Union the "transition" in its traditional interpretation has been concluded in ten of the Central East European countries. The transition to market based agriculture, however, is far from completion in Southern and Eastern Europe and especially in the CIS countries. International Association of Agricultural...

Dairy Quota and Farm Structural Change: A Case Study on the Netherlands AgEcon
Jongeneel, Roelof A.; Tonini, Axel.
This paper sets out to analyse the impact of milk quotas had on the dairy farm structure of the Netherlands. In addition projections on the likely farm structure under different milk quota scenarios are explored. Moreover mobility indicators characterizing structural change are developed and calculated. A Markov probability model is estimated relying on a generalized cross entropy approach. The introduction of milk quotas as of April 1, 1984 froze the dairy farm structural adjustment, at least initially. However, later on mobility started to increase, which is likely to reflect the quota tradability and lease possibilities. Moreover there is evidence that the milk quota regime has increased concentration of dairy production among farms with 50-69 cows. If...

Dairy reform scenarios with CAPSIM acknowledging quota rent uncertainty AgEcon
Witzke, Heinz Peter; Tonini, Axel.
The study provides an agricultural multi commodity analysis able to focus and investigate the ongoing EU milk reform. The analysis is carried with the Common Agricultural Policy SIMulation (CAPSIM) model which is a comparative-static, partial equilibrium modelling tool covering the whole of agriculture of EU member states. The model provides a reference run which is a "baseline scenario" where the 2003 CAP Reform is projected into the future. This scenario is compared to a "quota expiry" scenario where milk quotas are abolished by 2015, a "soft landing" scenario where further quota expansions are envisaged and an "early quota expiry" by 2009. Sensitivity analysis is done for different set of quota rent assumptions and export refund abolition. Key results,...

EU Dairy Sector: Impact of Luxemburg Reform, EU Enlargement and Trade Negotiations AgEcon
Bouamra-Mechemache, Zohra; Ali-Kein, Hela Hadj; Jongeneel, Roelof A.; Tonini, Axel; Requillart, Vincent.
The EU dairy sector is facing a period of significant changes that are due to three major decisions: the EU enlargement, the Luxembourg reform and on-going WTO negotiations. To evaluate the impact of such changes we developed a model of the EU and world dairy industry. The model is composed of two modules that interact: a milk and beef supply module and a dairy industry module. In this paper we present the model and focus on elements that are crucial for a better understanding of the impact of reforms: quota rents in the EU, evolution of production in the new member states and trade policy.

Modelling the Dairy Farm Size Distribution in Poland Using an Instrumental Variable Generalized Cross Entropy Markov Approach AgEcon
Tonini, Axel; Jongeneel, Roelof A..
The aim of this paper is to analyse the evolution of the dairy farm structure of Poland during the post-socialist period. First the paper focuses on how the farm structure has changed over time and what path it is likely to follow in the coming decade. Second, it is tested whether the evolution of farm size is explained by non-stationary effects. Finally, several statistical indicators are computed on farm mobility and on which farms are likely to survive. An instrumental variable generalised cross entropy Markov chain approach which incorporates prior information is applied for estimation. Prior information included general and plausible information on farm mobility and structural adjustments based on independent literature. The projections show that...

THE 'MILK QUOTAS RENT PUZZLE' IN THE EU: ECONOMIC SIGNIFICANCE, REVIEW, AND POLICY RELEVANCE AgEcon
Jongeneel, Roelof A.; Tonini, Axel.
In the so-called Common Agricultural Policy (CAP) 'Health Check' the European Commission has recently proposed gradual transitional measures to allow a 'soft landing' of the milk sector to quota expiry. The aim of this paper is to support policy makers to get better insights in the implications of some of the most important economic assumptions and empirical choices made in partial equilibrium models focusing on dairy. Three partial equilibrium models are considered: the Agricultural Member states MODeling (AGMEMOD) model, the Common Agricultural Policy SIMulation (CAPSIM) model, and the European Dairy Industry Model (EDIM). The paper analyzes how the most important economic supply components, as they are part of the three key dairy models, affect milk...
