Interactions of economic growth, energy consumption and the environment in the context of the crisis – A study with uncertain data

The global financial crisis has brought severe impacts on the Portuguese economy. In this context, the Portuguese government has recently adopted harsh measures that will have deep impacts on peoples' lives. This paper discusses the influence of these measures on economic growth, social well-being, energy consumption as well as its impacts on the environment using a multi-objective linear programming model based on input–output analysis. Uncertainty is captured taking into account different model coefficient settings by means of interval programming tools.
