Asymmetric Tax Policy Responses in Large Economies With Cross-Border Pollution

We build a model of cross-border pollution between two large open economies, one importing the polluting good and the other exporting it, and derive their non-cooperative trade and environmental tax policies. We show among other things, that (1) in response to a bilateral reduction in trade taxes by both countries, the former country’s optimal policy is to lower its Nash emissions tax while the latter’s is to raise it, and (2) in response to an increase in emissions tax rates by both countries, the former country’s optimal reaction is to raise its Nash import tariff, while the latter’s is to reduce its Nash export tax. That is, in the present context, freer trade leads the exporting country to adopt stricter while the importing country laxer environmental tax policies.     

Openness in the Canadian economy: 1870–1988

The causal relation between openness and GDP and between exports and imports are examined. Causality test carried out in growth rates showed that over the period 1870–1988 openness, both narrowly and broadly defined, Granger-causes GDP growth; tests for the inverse causality produced mixed results, validating causality from GDP growth to export plus import growth, but rejecting causlaity from GDP growth to export growth; it was also found that export growth causes import growth, but not the opposite. Causality tests over four subperiods indicated the importance of openness for only the earliest phase of Canadian economic development. While the absence of causality in the later subperiods is largely compatible with the experience of the industrial countries, no meaningful comparison can be made between the experience of Canada and that of developing countries owing to causality variations of openness and to large differences in resource endowments.     

Public Goods,Tax Policies,and Unemployment in LDCs

We build a general equilibrium model of a small open economy characterized by unemployment and producing two privately traded goods and one nontraded public consumption good. The provision of public good is financed with an income tax or an excise tax on the manufactured good or an import tariff. Within this framework, the paper examines the effects of such policies on the country's unemployment ratio and welfare, and it derives the efficiency rules for public good provision for each policy instrument. It shows, among other things, that the private marginal cost of the public good always overstates its social marginal cost in the case of income taxes and may overstate it in the case of an excise tax on the manufactured good or a tariff even if the taxed good and the public good are substitutes in consumption.     

Quantitative Import Restrictions and Optimal Capital Taxes Under a System of Tax Credits

This paper examines the optimal capital tax policy under quantitative import constraints, and international capital tax credits. For a small capital-importing country, the optimal capital tax equals the foreign tax under a quota, and equals or exceeds the foreign tax under a VER. For a small capital-exporting country, the optimal policy towards capital is a zero tax under a quota, and a tax or a subsidy under a VER. Also examined are the welfare effects of capital taxes and trade liberalization, and the joint setting of the two policies, when both instruments are available to the government.     

A Family of Differential Input Demand Systems with Application to Greek Agriculture

This paper develops a family of input demand systems via alternative parametrisations of Theil's differential model. Each member of this family is as flexible as any other locally flexible functional form. More importantly, selection among the competing family members is possible via simple parameter restrictions. The family of differential input demand systems is applied to the agricultural sector in Greece for the period 1961–96. Formal tests suggest that the model with the CBS-type effects dominates the alternative models. Divisia and price elasticities are calculated from the selected model and a decomposition of changes in the demand for inputs into technical change, total input volume, substitution, and residual effects is performed. The empirical results are quite reasonable. Overall, the analysis in this paper indicates that, in certain cases, the differential approach may provide an attractive alternative to the dual approach in modelling production behaviour.     

Testing for the LOP under nonlinearity: an application to four major EU pork markets

This article develops an econometric procedure to test the validity of the Law of One Price (LOP) under nonlinearity and to distinguish between its strong and its weak version. The procedure is applied to four major EU pork markets using weekly prices from 1991 to 2008. The empirical results suggest that the markets are well integrated, with deviations from the steady‐state price differentials corrected nonlinearly. The LOP is valid for all market pairs and for the pair Germany–Spain it holds in its strong version.     

World Energy Council’s Global Energy Scenarios to 2060

Since 1970, global energy consumption has more than doubled. Conventional resources, in particular oil, gas and coal, had a dominant share in supply and covered most of the growth in demand in the past. Even in 2015, these fossil fuels still accounted for more than 80% of global primary energy consumption. The contribution of renewable energies to the total electricity generation was 23% in 2015, the same share as in 1970. Developments in the coming decades will differ substantially, however. Total energy consumption will rise at a much more moderate pace than in the past, e.?g. by up to one third by 2060. Electricity consumption will double during this period. But even this is a considerable slowdown in growth compared with the five-fold increase seen between 1970 and 2015. And, unlike in the past, the emerging rise in consumption will essentially be covered by renewable energy sources. This is true especially for the electricity sector. This comparison with developments in the past shows the extent of the global energy transformation that may be expected in future. These developments are reflected in three global scenarios, which were published by the World Energy Council in October 2016. The results of this flagship study World Energy Scenarios to 2060 are mirrored with the main findings of the IEA’s World Energy Outlook and the U.S. EIA’s International Energy Outlook. The most important challenge indicated by the results of the mentioned studies is: the transformation, which is expected in the covered scenarios is not sufficient, in order to achieve the target of limiting the global temperature increase to less than 2 degrees Celsius compared to pre-industrial levels that was agreed by the international community of states in Paris at the end of 2015. It will be highlighted, which strategies could meet the requirement cost-efficiently—a prerequisite for its success.
