“…Some examples of this confluence are the environmentally-extended input-output databases [31] and a large and growing number of empirical studies using hybrid methods. Pauliuk and colleagues [32,33] call for the integration of this range of component models from an Industrial Ecology perspective, and they amply demonstrate the objectives shared with economists. The ideas laid out in this paper are meant to reinforce other efforts for deepening the integration between Input-Output Economics and Industrial Ecology.…”

“…The WIO model has been applied in a number of empirical studies [54][55][56][57][58][59][60][61] and is used by both economists and engineers. The existing WIO model makes use of the one-region, static input-output framework, but efforts are in place to situate it in a global setting, or a dynamic one, or both: see [32,33,62,63].…”

Abstract:We are at an early stage of a massive global build-up of public infrastructure. Long lifetimes, high money costs and resource-intensity, and the rippling effects of the built environment on all aspects of daily life call for informed public conversation about the available choices before they become a fait accompli. Substantial literatures address the phenomenon in terms of economic development, resource scarcities, impacts on climate and ecosystems, technological options, human rights, funding sources, system governance, inter-governmental agreements. This paper describes a modeling framework that integrates some of these concerns about the differential impacts of large-scale centralized infrastructure systems, smaller-scale decentralized systems, and hybrid combinations. Building on existing collaborations between economists and engineers, the paper proposes a case-study research strategy to organize new types of technical information to supplement existing databases of the world economy. The paper describes needed model extensions to estimate money costs, resource requirements, resource recovery potential, and jobs and livelihoods under alternative infrastructure assumptions. The agenda supports the Sustainable Development Goals (SDGs) by identifying and evaluating globally relevant alternative infrastructure designs. The SDG process, in turn, provides both the global network and the concern to promote local development to which the proposed effort aims to contribute.

“…Endogenous, land-class specific factor scarcity rents are earned in addition to the exogenous factor price by factors that are fully utilized; factors that are not fully utilized receive only the exogenous component of the factor price. For a detailed discussion of the treatment of factor prices in the World Trade Model see [12,14].…”

“…These parameters were computed for each region by dividing the total amount of land in a specific land-class/land-use category by the agricultural commodity quantities produced on that amount of land in the base year of 1990. The remaining data were extracted from the World Trade Model database [12]. The model is solved using the GAMS (General Algebraic Modeling System) optimization software.…”

“…The WTMCL model takes the form of a linear optimization problem that integrates a fully generalized system of trade based on comparative advantage for m regions, n goods and k factors, Duchin's World Trade Model [12], with the spatial analogues approach of Darwin et al [13], which quantifies climatic responses of land resources under alternative climate assumptions.…”

This paper uses the World Trade Model with Climate Sensitive Land (WTMCL) to evaluate possible future land-use changes associated with adaptations to climate change in a globalized world. In this approach, changes in regional agricultural production, which are based on comparative advantage, define patterns of land use change in agriculture in all regions of the world. We evaluate four scenarios that combine assumptions about future increases in food demand and future changes in land endowments of different productivities associated with climatic conditions: each scenario generates distinct patterns of regional specialization in the production of agricultural commodities and associated land-use change. The analysis also projects future food availability under the simulated conditions and the direction of likely changes in prices of the major agricultural commodity groups.
