This paper develops a multi-sector computable general equilibrium (CGE) model with specific features for Greece and the non-EU Rest of the World (RoW). The novelty of this work stems from the lack of energy-focused CGE models for Greece in the current literature. The study's objective is to determine how the Greek economy would react if a 30% import tariff and a quota of 67% on energy imports and 35% on remaining imports were implemented. Furthermore, if quotas and tariffs are in force, the Greek economy will initiate countermeasures by increasing investment in renewable energies through substitution and a 35% subsidy. To quantify this, the 2015 Input-Output (I-O) table for Greece and the non-EU RoW was used. To offer a better understanding, the 36 production sectors have been divided into Agriculture, Energy, Manufacturing, and Services. The quota scenario resulted in a reduction in all sectors in domestic production in terms of output and domestic uses, with some sectors experiencing around a 30% reduction. Renewable energy investments, on the other hand, have proven to be effective for domestic production, increasing output and domestic uses by (6.561%) and (7.886%), respectively. In terms of import tariffs, prices have increased, resulting in a significant decrease in household consumption that exceeds 30% in several sectors. Finally, policy recommendations for addressing these trade barriers and Greece's renewable energy opportunities are proposed. [ABSTRACT FROM AUTHOR]

The considerable relevant size of the tourism sector for some economies, together with this sector's vulnerability to CC, renders this study an insightful aid to tourism demand forecasting. The paper applies a pooled mean group (PMG) model to identify climate parameters that affect tourism demand. Then, it continues with an input–output table analysis to show the transmission effects of CC on each component of the tourism sector. The PMG model imposes homogeneity on the long-run coefficients and while less restrictive, it is more efficient than other methods of the same family. The estimated gravity equation enables comparisons of the baseline scenario with various different scenarios of CC and finds how tourist arrivals could be affected up to 2080. Our results suggest that there is mostly a positive relationship of the squared difference of temperature and precipitation between Greece and tourist origin countries. Our findings also suggest that CC could lead to a fall in Greek GDP between 1.79 and 2.61%. We believe that our findings will help design appropriate policy actions that may offset or alleviate these negative future negative impacts of CC. [ABSTRACT FROM AUTHOR]

Abstract: Mathematical models of competing species defined by ordinary differential equations are considered to construct a model for analysing the spatial dimension of employment. Analysis of the points of equilibrium is given in an application of the model using data on employment in High Technology Sectors (HTS), for the period 1999-2008, for Greece. The findings suggest that there is tendency of movement in employees in HTS in Greece from the Attica region to the Rest of Greece. In the long-run equilibrium it was found that the employment in Attica will be between the levels of 2007 and 2008 while it will increase in the periphery of Greece. [Copyright &y& Elsevier]
