Agricultural Household Models: Genesis,Evolution, and Extensions

This paper offers a synthesis of agricultural household modeling, its evolution and uses; presents a general yet simple agricultural household model, estimated with Mexican village data and programmed using General Algebraic Modeling System software; and uses this model to explore household-level impacts of agricultural policy changes on production and incomes under alternative rural-market scenarios. We point out limitations of household-farm models in heterogeneous rural economies and discuss how to integrate multiple household models into economy-wide models designed to overcome these limitations.     

Poverty, income distribution and CGE micro-simulation modeling: Does the functional form of distribution matter?

This paper explores income distribution modeling approaches for poverty analysis in a CGE micro-simulation context. Income distribution functional forms such as the lognormal, Pareto, beta distribution and empirical methods are currently used in CGE models in parallel with the estimation of FGT poverty indices. The particular methods or functional forms used in this context are not always clearly defined and justified. In this paper, we investigate and provide better criteria for selecting a functional distribution for poverty analysis. To achieve this, we apply parametric estimation to seven functional forms and compare the results to a purely “empirical” method. The results showed that no single form is more appropriate in all instances or for all household subgroups. The choice of a modeling approach should be motivated by a search for best fit and should be based on appropriate statistical tests. Selecting inappropriate distributional forms can lead to biased results in terms of poverty analysis. Introducing functional forms in the empirical approach can also provide greater confidence in the results obtained.

The Cartagena Protocol: Implications for Regional Trade and Technology Development in Africa

The majority of African countries have ratified or acceded to the Cartagena Protocol on Biosafety, and many have received support through the Global Environment Facility and the UN Environment Programme for development of their National Biosafety Frameworks. This article examines the extent to which these frameworks are aligned with the goals of the Regional Economic and Regional Research Communities of which they are members. Many national approaches lack alignment with regional trade, economic, science and technology policies. The strict application of the precautionary principle and the imposition of costly administrative hurdles are likely to hinder intra‐regional trade and technology development.     

Global Governance,neoliberalism and national responses: The case of Bangladesh’s ready‐made garment (RMG) sector

This article on the ready‐made garment (RMG) sector of Bangladesh shows how over‐reliance on foreign capital for development financing and deregulated investment—a hallmark of neoliberal economic arrangements—undermines the incorporation of SDGs’ and INGOs’ equity principles, contributing to biased policy responses yielding unequal outcomes. The article cautions that while countries prioritize economic growth over social and environmental nourishment and continue to adopt neoliberal economic policies to promote economic growth, inequity is unavoidable, if not inevitable. Thus, the way forward may be to shift the focus of ‘development’ from the economy to society, to building ‘good societies’ where institutions and strategies, including those that contribute to economic growth, are organized such that these complement not compromise the evolution of such societies.
