Economic analysis of the impact of adopting herd health control programs on smallholder dairy farms in Central Thailand

The economic impact of adopting herd health programs for mastitis and reproduction by small-scale dairy producers of Central Thailand was assessed using a policy analysis matrix (PAM). Following a reduction in the incidence of bovine disease on adopter farms, an increase in private net profits is observed. More importantly the social costs of supporting dairy farmers is reduced; the PAM effective protection coefficient was reduced by 35% for mastitis program adopters and by 44% for reproductive program adopters, indicating improved social efficiency of dairy policy. Other indicators of efficiency and policy implications are discussed.     

The Conflicted State and Agrarian Transformation in Pink Tide Venezuela

Can radical political‐economic transformation be achieved by electoral regimes that have not thoroughly reconstructed the state? Contemporary Venezuela offers an optimal venue for examining this question. The Chavista movement did not replace the previous state: instead, its leaders attempted to reform existing state entities and establish new ones in pursuit of its transformation agenda. It has also used its oil wealth to support cooperatively‐oriented economic activity, without necessarily fundamentally altering the property structure. Thus, the social change‐oriented political economy exists alongside the traditional one. Focusing on agrarian transformation, we examine ethnographically how these factors have impacted the state's capacity to attain its goal of national food sovereignty. We find that the state's ability to accomplish this objective has been compromised by lack of agency‐level capacity, inter‐agency conflict and the persistence of the previously‐extant agrarian property structure. These dynamics have influenced the state to shift from its initial objective of food sovereignty to a policy of nationalist food security.     

Determinants of Intra-GCC Food Trade

Using panel data for six Gulf Cooperation Council (GCC) countries from 1995–2014, we assess the impacts of several major economic variables on intra-GCC food exports, and on GCC food exports to the world. The GCC customs union had minimal impact on intra-GCC food exports, but occasioned a significant reduction in GCC food exports. Unlike GCC food exports, intra-GCC food exports occurred among countries with similar relative factor endowments, in agreement with the Linder Hypothesis. Rising incomes and exchange rates played significant roles in both intra-GCC food exports and GCC food exports, while distance has lost its once-dominant role.     

Private credit in 129 countries

We investigate cross-country determinants of private credit, using new data on legal creditor rights and private and public credit registries in 129 countries. Both creditor protection through the legal system and information-sharing institutions are associated with higher ratios of private credit to gross domestic product, but the former is relatively more important in the richer countries. An analysis of legal reforms shows that credit rises after improvements in creditor rights and in information sharing. Creditor rights are remarkably stable over time, contrary to the hypothesis that legal rules are converging. Finally, legal origins are an important determinant of both creditor rights and information-sharing institutions. The analysis suggests that public credit registries, which are primarily a feature of French civil law countries, benefit private credit markets in developing countries.     

Credit constraints and smallholder dairy production in the East African highlands: application of a switching regression model

Accurate assessment of farmers' credit constraint condition is important in order to understand the circumstances under which credit would have its greatest impact. In this study a switching regression model was used to determine the impact of credit on smallholder dairy farms in the East African highlands using farm level data from Ethiopia and Kenya. Farmers were classified as credit constrained or credit non-constrained based on their responses from the farm level surveys. No consistent relationship was found between farmers' credit constraint condition and their borrowing status. Most of the variation in milk output per farm was explained by the number of crossbred milking cows in the dairy herd. As credit is likely to facilitate investment in crossbred dairy cows it will have substantial impacts on smallholder dairy farms especially if it is targeted to credit constrained farms.     

Bayes estimates of distance‐to‐market: transactions costs,cooperatives and milk‐market development in the Ethiopian highlands

Rationalizing non‐participation as a resource deficiency in the household, this paper identifies strategies for milk‐market development in the Ethiopian highlands. The additional amounts of covariates required for positive marketable surplus—‘distances‐to market’—are computed from a model in which production and sales are correlated; sales are left‐censored at some unobserved threshold; production efficiencies are heterogeneous; and the data are in the form of a panel. Incorporating these features into the modeling exercise is important because they are fundamental to the data‐generating environment. There are four reasons. First, because production and sales decisions are enacted within the same household, both decisions are affected by the same exogenous shocks, and production and sales are therefore likely to be correlated. Second, because selling involves time and time is arguably the most important resource available to a subsistence household, the minimum sales amount is not zero but, rather, some unobserved threshold that lies beyond zero. Third, the potential existence of heterogeneous abilities in management, ones that lie latent from the econometrician's perspective, suggest that production efficiencies should be permitted to vary across households. Fourth, we observe a single set of households during multiple visits in a single production year. The results convey clearly that institutional and production innovations alone are insufficient to encourage participation. Market‐precipitating innovation requires complementary inputs, especially improvements in human capital and reductions in risk. Copyright © 2008 John Wiley & Sons, Ltd.     

Corruption and firm behavior: Evidence from African ports

This paper investigates how corruption affects firm behavior. Using an original and unusually rich dataset on bribe payments at ports matched to firm-level data, we observe how firms adapt to different types of corruption by adjusting their transport strategies. Our results suggest that firms respond to the price effects of corruption, organizing production in a way that increases or decreases demand for the public service.     

Agroindustrialization through institutional innovation Transaction costs, cooperatives and milk-market development in the east-African highlands

Some small-holders are able to generate reliable and substantial income flows through small-scale dairy production for the local market; for others, a set of unique transaction costs hinders participation. Cooperative selling institutions are potential catalysts for mitigating these costs, stimulating entry into the market, and promoting growth in rural communities. Trends in cooperative organization in east-African dairy are evaluated. Empirical work focuses on alternative techniques for effecting participation among a representative sample of peri-urban milk producers in the Ethiopian highlands. The variables considered are a modern production practice (cross-bred cow use), a traditional production practice (indigenous-cow use), three intellectual-capital-forming variables (experience, education, and extension), and the provision of infrastructure (as measured by time to transport milk to market). A Tobit analysis of marketable surplus generates precise estimates of non-participants' 'distances' to market and their reservation levels of the covariates — measures of the inputs necessary to sustain and enhance the market. Policy implications focus on the availability of cross-bred stock and the level of market infrastructure, both of which have marked effects on participation, the velocity of transactions in the local community and, inevitably, the social returns to agroindustrialization.     

A Cox Parametric Bootstrap Test of the von Liebig Hypotheses

This study uses a Cox parametric bootstrap test to select between two specifications of the von Liebig hypothesis, a switching regression (SR) model, and a linear response function with a stochastic plateau. Specifying the production function as a linear response function with a stochastic plateau yields a superior approximation of the data for livestock gain as a function of forage allowance than the SR approach.
Dans la présente étude, nous avons utilisé la technique du bootstrap paramétrique de Cox pour choisir entre deux caractéristiques de l'hypothèse de von Liebig: un modèle de régression avec changement de régime et une fonction de réponse linéaire avec plateau stochastique. établir la fonction de production comme une fonction de réponse linéaire avec plateau stochastique offre une meilleure approximation des données sur le gain de poids du bétail comme fonction de l'apport de fourrages comparativement au modèle de régression avec changement de régime.
