| Abstract: | This paper examines how some factors affect the greenhouse effect of fifteen countries in European Union with fixed and random effects, while we also investigate the case of the Arch effects presentation. Finally we estimate a neural network model to examine how all the factors affect the greenhouse effect and we compare the forecasting performance with that of fixed or random panel data estimation. |

| Abstract: | In 2007 Slovenia launched a comprehensive reform of its tax system. To estimate the different proposals (including a flat-tax proposal) and their overall effect on individual taxpayers and government budget a static micro-simulation model was constructed and combined with a computable general equilibrium model. It uses a large, comprehensive database (6% of the population) provided by relevant ministries and government agencies and proved to be a reliable tool during implementation of the reform. In the paper, the main characteristics of both models are presented along with the results of different reform scenarios, including those which finally passed the parliament and now form part of the Slovenian tax system. |

| Abstract: | This research paper intends to analyse: (a) the impacts of ASEAN trade liberalization on the macroeconomy variables – gross domestic product (GDP), Terms of Trade (ToT), balance of trade, inflation and real wage – and agricultural industries (output, exports and imports) in the ASEAN 6 countries (Indonesia, Malaysia, the Philippines, Thailand, Singapore, and Viet Nam); and (b) the impact of trade liberalization on income distribution in Indonesia. A multi-country and multi-commodity computable general equilibrium (CGE) GTAP model has been used as the main tool of analysis. |

| Abstract: | Who benefits from public spending? Who bears the burden of taxation? How desirable is the distribution of net benefits from the operation of a tax-benefit system? This paper surveys basic concepts, methods, and modeling approaches commonly used to address these issues in the context of fiscal incidence analysis. The review covers the incidence of both taxation and public spending. Methodological points are supported by country cases. The effective distribution of benefits and burdens associated with fiscal policy depends on the size of the government, the distributive mechanisms involved, and the incentives properties of the policy under consideration. This creates a need for analytical methods to account for both individual behavior and social interaction. The approaches reviewed include simple reduced form regression analysis, microsimulation models (both the envelope and discrete choice models), computable general equilibrium modeling, and approaches that link computable general equilibrium models to microsimulation models. Explicit modeling facilitates the construction of counterfactuals to back up causal analysis. Social desirability is assessed on the basis of progressivity along with deadweight loss. |

| Abstract: | We propose a new hybrid recommender system that combines some advantages of collaborative and content-based recommender systems. While it uses ratings data of all users, as do collaborative recommender systems, it is also able to recommend new items and provide an explanation of its recommendations, as do content-based systems. Our approach is based on the idea that there are communities of users that find the same characteristics important to like or dislike a product. This model is an extension of the probabilistic latent semantic model for collaborative filtering with ideas based on clusterwise linear regression. On a movie data set, we show that the model is competitive to other recommenders and can be used to explain the recommendations to the users. |
