Bargaining Coalitions in the WTO Agricultural Negotiations

This paper aims to understand the structural features of bargaining coalitions in the Doha Round of the WTO. We provide an empirical assessment of the preferences of each negotiating actor considering general economics indicators, development levels, structure of agricultural sectors and trade policies. Bargaining coalitions are analysed by grouping countries using a cluster analysis procedure. The clusters are compared with existing coalitions in order to assess their degree of internal homogeneity as well as their common interests. Such a comparison allows the identification of possible ‘defectors’, i.e. countries that, according to their economic conditions and policies, seem to be relatively less committed to the positions of the coalition they join. In addition, the ex‐post analysis of the counterfactual coalitions sheds light on the ‘distance’ between different coalitions as well as between individual countries and the best alternative group available. Empirical results confirm our research hypothesis: clusters of structurally homogeneous countries well represent existing bargaining coalitions. In particular, the G‐20 shows a high degree of internal coherence, which, in our framework, may provide a clue to the ‘sustainability’ of this coalition and to its relevance in the Doha Round negotiations.     

The impact of thin‐capitalization rules on the location of multinational firms’ foreign affiliates

This paper examines how restrictions on the tax deductibility of interest cost affect location choices of multinational corporations (MNCs). Many countries have introduced so‐called thin‐capitalization rules (TCRs) to prevent MNCs from shifting their tax base to countries with lower tax rates. As of 2012, in our sample of 172 countries, 61 countries have implemented a TCR. Using information on nearly all new foreign investments of German MNCs, we provide a number of new and interesting insights in how TCRs affect the decision of where to locate foreign entities. In particular, stricter TCRs are found to negatively affect location choices of MNCs. Our results include estimates of own‐ and cross‐elasticities of location choice and also novel results on the relative importance of tax base vs. tax rate effects. We finally provide estimates for different uncoordinated as well as coordinated policy scenarios.     

Environment, human development and economic growth

Over the last few years, environmental issues have entered into policy design, particularly development and growth policies. Natural resources are considered necessary production inputs and environmental quality is considered a welfare determinant. The integration of environmental issues into economic growth and development theories and empirics is currently widely analyzed in the literature. The effects of natural resources endowment on economic growth are mainly analyzed through the so-called Resource Curse Hypothesis (RCH) whereas the effects of economic growth on environmental quality are part of the Environmental Kuznets Curve (EKC). Furthermore, recent contributions on RCH and EKC have shown the important role of institutions and human development dimensions in building a sustainable development path. In this paper, we attempt to analyze the causal relationships between economic growth, human development and sustainability combining the RCH and EKC models and adopting a human development perspective. Results confirm the importance of high institutional quality and investments for human capital accumulation in order to build a sustainable development path.     

Where does return and volatility come from? The case of Asian ETFs

We analyze return and volatility of Asian iShares traded in the U.S. The difference in trading schedules between the U.S. and Asia offers a unique market setting that allows us to distinguish various return and volatility sources. We find Asian ETFs have higher overnight volatility than daytime volatility, explained by public information released during each local market's trading session. Local Asian markets also play an important role in determining each Asian ETF return. Nonetheless, returns for these funds are highly correlated with U.S. markets, indicative of the effects of investor sentiment and location of trade. Finally, returns in the U.S. market Granger-cause returns in all six Asian markets are analyzed.     

Regional Integration and the Co-ordination of Capital Income Taxation

This paper addresses the question of the need for income tax harmonization in the context of regional integration. It analyses the international distortions and fiscal interdependence arising in the presence of tax rate differentials both under a theoretical and an empirical perspective, and with reference to actual experiences of harmonization attempts. Attention is also paid to the influence of the countries' size on the results, to the strategic behaviour of countries under different international taxations rules, and to the relationships with the countries excluded by the integration process. International tax uniformity does not appear to be the preferable solution, even if some form of concerted agreements might help in reducing inefficiencies deriving from taxation differentials. For instance, in the case of highly mobile factors, like financial capital, if the integrating countries apply the source principle and the interest rate is the same across them, the source-based tax rate on non residents must equal the residence country tax rate on residents. Such a rule would allow the countries to set autonomously their tax rate and, at the same time, eliminate cross-border effects. If there are more than two integrating countries, the tax rates on non residents should discriminate according to the internal tax rate of the residence country.
