Анализ оболочки данных (DEA) - это относительно новая методика измерения технической эффективности. Если сформулировать техническую эффективность определенного...

Die Data Envelopment Analysis (DEA) ist eine relativ neue Methodik zur Messung der technischen Effizienz. Definiert man technische Effizienz einer Organisationseinheit (Decision Making Unit - DMU) als Verhältnis der produzierten Güter und Dienstleistungen (Outputs) zu den eingesetzten...

In village economies, insurance networks are key to smoothing shocks, while production networks can propagate them. The interplay of these networks is crucial. We show that a significant health expenditure shock to one household propagates to other linked households via supply-chain and labor...

Temporal climate risk weighs heavily on many of the world's poor. Model-based climate forecasts could benefit such populations, provided recipients use forecast information to update climate expectations. We test whether pastoralists in southern Ethiopia and northern Kenya update their...

This paper explores the value of mangrove systems as a breeding and nursery habitat for off-shore fisheries, focusing on mangrove-shrimp production linkages in Campeche State, Mexico. We develop an open access fishery model to account explicitly for the effect of mangrove area on carrying...

Much of the world's gene pool is located in tropical rainforests, which are being destroyed at an alarming rate. Proper management of protected forests is crucial to avoid further loss of forest resources and biodiversity. Resource extraction by local communities has been cited as a major...

This paper analyses the relationship between rural poverty and soil degradation in the context of a shifting cultivating community. A deterministic optimal control model demonstrates how a representative household's labour allocation affects the natural resource base on which its livelihood...

The relationship between land investment and tenure security is usually tested in land scarce but peaceful areas. This article examines instead the effects of land abundance and war for investment and tenure security. The paper demonstrates that war enhances land abundance. This implies that...

In a careful and thorough empirical study, Christopher Udry (1996) shows convincingly that, in a large sample of West African households, household resource allocations were not Pareto efficient. This paper argues that observation of the Pareto inefficiency of a household resource allocation...

We analyze a dynamic and stochastic ecological-economic model of grazing management in semi-arid range lands. The non-equilibrium ecosystem is driven by stochastic precipitation. A risk averse farmer chooses a grazing management strategy under uncertainty such as to maximize expected utility...
