Grid tariffs are the main source of income for distribution system operators (DSOs). Reductions of tariffs increase the cost pressure on DSOs; assuming they work efficiently tariff reductions potentially lead to a decrease of the electricity system's quality if no reliability of supply criteria are incorporated in the regulatory system. Our statistically analysis shows that the correlation betw...

MUCH attention has been devoted to the study of the structure of tariffs in industrial nations and its impacts on the level and composition of their imports from developing countries. Studies have identified two sources of bias against imports from developing countries inherent in tariff structures of industrial nations. First, tariffs used by industrial nations have been found to bear more hea...

This paper studies the effects of tariffs on intra-firm trade. Building on the Antràs and Helpman (2004) North-South theoretical framework, the author shows that higher Northern tariffs reduce the incentives for outsourcing and offshoring, while higher Southern tariffs have the opposite effects. The author also shows that increased offshoring and outsourcing imply a descrease in the ratio of No...

In communication, information, and other industries, three-part tariffs are becoming increasingly popular. A three-part tariff is defined by an access price, a usage allowance, and a marginal price for any usage in excess of the allowance. The nonlinear-pricing literature has focused primarily on two-part tariffs. We show that consumer behavior differs under three-part tariffs, in particular re...

We show that a relatively small menu of three-part tariffs (3PTs) can be more profitable and, sometimes, socially more desirable than a larger menu (more items) of two-part tariffs (2PTs). Often, a single three-part tariff can beat a sorting menu comprising multiple two-part tariffs. Moreover, this 3PT menu can be designed with less information about consumer preferences, relative to the menu o...

— This paper explores tariff reform in Ethiopia, Kenya, Tanzania and Uganda between the early 1990s and early 2000s. Tariffs were reformed in an across the board manner consistent with implementing World Bank programs: the average tariff was reduced and the dispersion of tariffs was compressed, with the highest tariffs being eliminated. There is limited evidence of political economy influences ...

This paper shows that governments have no incentive to introduce non-tariff barriers when they are free to set tariffs but they do when tariffs are determined cooperatively. We then show three results. First, with trade liberalization, there is a progression from using tariffs only to quotas, and to antidumping constraints (when quotas are jointly eliminated). Second, there is a narrowing of th...
