Computable general equilibrium (CGE) models are ubiquitous in energy and environmental economics research. Recent technological advancements in electricity fuels, generation technologies, and environmental policies which target specific generation technologies (e.g., emission regulations) have motivated detailed CGE modeling of the electricity sector. Modeling these issues requires distinct ele...

Software testing is required to detect the faults and to ensure the quality of the software under development. Usually, test suites are used to evaluate the software system during the software development cycle. But often test suites contain more redundant test cases due to overlapped test objectives. So, the test-suite reduction is an important step to reduce the number of test cases so as to ...

In this paper we consider the problem of repairing missing is-a relations in ontologies. We formalize the problem as a generalized TBox abduction problem (GTAP). Based on this abduction framework, we present complexity results for the existence, relevance and necessity decision problems for the GTAP with and without some specific preference relations for ontologies that can be represented using...

This paper explores trade policy and investment linkages in the GTAP Model. This is done under alternative steady-state closure rules linking trade to consumption, production, and investment, and emphasizing the general equilibrium nature of capital accumulation mechanisms. When policy shocks are capital friendly, induced investment may be greater than suggested by current savings rates. As a r...

The universe of existing CGE models can be divided into 3 broad categories. The first class of models (of which the standard GTAP model is a classic example) emphasizes the static effects of policy related to general equilibrium resource reallocation. The second involves scale economics and imperfect competition and the third involves dynamic accumulation effects. Development of the second clas...

Focusing on the global trading relationship aggregated at the level of 15 regions and 10 sectors, we investigate in this paper the welfare effects of preferential trade liberalisation in South Asia from several simulation perspectives. The static version of the Global Trade Analysis Project (GTAP) model shows that countries that are initially more protected (such as India) are likely to capture...

The GTAP version 5 dataset has three transportation sectors. However, household transportation expenditures related to private automobiles are not represented explicitly in the data. We augment the existing GTAP data to separately disaggregate household transportation and explore the implications of this extension in the MIT Emissions Predictions and Policy Analysis (EPPA) model. Climate policy...

This paper discusses future directions in global trade analysis from the perspective of the Global Trade Analysis Project (GTAP) network. The first section offers a projection of where the GTAP network might be in the year 2010. This is followed by an analysis of the basic drivers of change in global trade analysis. These include: network externalities and the push for greater openness in both ...

Sound event detection (SED) is the task of finding identities sound events, as well their onset and offset timings from audio recordings. When complete timing information not available in training data, but only are known, SED should be solved by weakly supervised learning. The conventional U-Net with global weighted rank pooling (GWRP) has shown a decent performance, extensive computation dema...

According to the Global Burden of Disease study (Cohen et al., 2017), in 2015 ambient air pollutant emissions caused 4.2 million deaths and a loss 103.1 disability-adjusted life-years, making it fifth-ranked global risk factor. In terms welfare costs mortality illnesses associated with outdoor emissions, estimates for range between $2.7-3.2 trillion (Coady 2015; OECD, 2016). Still, while greenh...
