This paper adds a nonrenewable resource to capital and labor in the neoclassical growth model. The nonrenewable resource introduces its depletion dynamics and expands the influence of input substitution on the growth path. Optimal depletion implies a rising resource price but investment or labor growth may raise extraction along the growth curve. Substitution between inputs plays a critical rol...

This paper investigates the implications of an intertemporally dependent demand structure in the market for an exhaustible resource. The demand structure is derived endogenously in a partial equilibrium model where price-taking users combine the resource with capital to produce final output. It is shown that, when demand for the resource is modelled explicitly as a derived demand, the common as...

Cloud manufacturing is characterized by large uncertainties and disturbances due to its networked, distributed, loosely coupled features. To target the problem of frequent cloud resource node failure, this paper proposes (1) three substitution strategies based on redundancy (2) a new robustness analysis method for systems combination complex network multi-agent simulation. First, simulation mod...

Non-renewable and renewable resources are imperfect substitutes due to technical and geographical constraints. What is the role of imperfect substitution on the optimal transition path to the clean technologies? We address this question by characterizing the optimal growth path and resource use of an economy. We show that the economy initially starts with using the non-renewable and renewable r...

This paper provides a general framework for service discovery, composition and substitution in a mobile adhoc network scenario. Knowledge representation techniques and approaches are exploited and adapted to the highly flexible and variable ubiquitous computing environment. A polynomial algorithm for composing and orchestrating mobile resources is outlined. Also is presented a simple approach t...

The one-demand Hotelling model fails to explain the observed specialization of nonrenewable resources. We develop a model with multiple demands and resources to show that specialization of resources according to demand is driven by Ricardian comparative advantage while the order of resource use over time is determined by Ricardian absolute advantage. An abundant resource with absolute advantage...

We propose an unsupervised system for a variant of cross-lingual lexical substitution (CLLS) to be used in a reading scenario in computer-assisted language learning (CALL), in which single-word translations provided by a dictionary are ranked according to their appropriateness in context. In contrast to most alternative systems, ours does not rely on either parallel corpora or machine translati...
