As primeiras décadas do século XXI têm sido marcadas por uma corrida global por terras, desencadeada pelas crises agroalimentar, energética, climática e econômico-financeira. O objetivo deste artigo é analisar se os Estados Unidos estiveram na rota dessa corrida. Para tanto, examinamos dados do Departamento de Agricultura dos Estados Unidos (United States Department of Agriculture – USDA) e bibliografia especializada, e identificamos que a porção de terras em mãos estrangeiras dobrou entre 2004 e 2014.

This study integrates situs theory as defined by Andrews (1971) into comparative investment analysis, approaching a single use development from the perspective of modern investment theory and a potential mixed use development on the same site as a portfolio of uses generating portfolio risk and return trade-offs. The theoretical integration of situs theory, rent theory and portfolio/investment economics is tested against a statistically significant number of development proposal case studies, conducted during distinct economic phases (over time).

Publication évaluée par des pairsavril, 2018Royaume-Uni, États-Unis d'Amérique, Asie, EuropeDespite their recognized agricultural sustainability benefits, mixed crop-livestock farms have declined in the Northern hemisphere. As such, crop-livestock integration beyond the farm level is a promising alternative to this trend, but the knowledge of critical factors and strategies towards its successful implementation is still lacking. We developed an analytical framework to assess the critical determinants of the emergence and outcomes of integration, which helped us understand farmers’ collective strategies for reducing integration transaction costs.

The spatial distribution of vegetation trends identified by time series analysis of the normalized difference vegetation index (NDVI) for the Mongolian grasslands was cross-referenced with the recently obtained land use/cover data and socioeconomic information in the geographic domain. Global Inventory Modeling and Mapping Studies (GIMMS) dataset with an 8-km resolution provided by the Global Land Cover Facility (GLCF) of the United States were used to compute the vegetation trends.

This paper argues that law and economics has not come to grips with Arrow's limitation on social welfare economics nor with the evolutionary character of economic and legal institutions. Arrow's theorem makes the concept of a socially efficient economic institution dependent on a prior allocation of property rights. A socially efficient result is efficient only within the bounds of the initial allocation of property rights. A differing initial

This study develops a dynamic multi-output model of farmers crop allocation decisions that allows estimation of both short-run and long-run adjustments to a wide array of economic incentives. The method can be used to inform decision makers on a number of issues including agricultural policy reform and environmental regulation. The model allows estimation of dynamic effects relating to price expectations adjustment, investment lags, and crop rotation constraints.

In Canada, where public ownership of forestland is prevalent, a central decision facing policy makers is how to allocate timber resources to private forest companies. Debates tend to focus around what proportion of the annual harvest should be devoted to markets opposed to long-term contracts. To give a guide to policy makers, we surveyed forest firms from New Zealand and Sweden where this decision is based purely on a commercial basis. On average, mills source fifty percent of their fibre from the market.
