The design of tariff schemes for packet-based network services, especially for Differentiated Internet Services, has turned out to be a non-trivial task. This is mainly due to the issue of how to account for the immense number of individual packets. This paper proposes a paradigm shift and argues that the solution of this feasibility problem is not a matter of coping with complexity, but instea...

The price-wedge method yields a tariff-equivalent estimate of technical barriers to trade (TBT). An extension of this method accounts for imperfect substitution between domestic and imported goods and incorporates recent findings on trade costs. We explore the sensitivity of this revamped tariff equivalent estimate to its determinants (substitution elasticity, preference for home good, trade co...

This paper challenges the conventional wisdom that exclusive owners of an advanced technology are always better off when producing as a monopolist than when competing against another firm. Competition against a less efficient firm weakens the power that a host country can exert on the incumbent in the form of its tariff policy. We show that this gives a motive for a monopolist to license its te...

This paper theoretically and empirically explores bargaining delay in tariff negotiations. By imposing a bargaining structure in an equilibrium trade framework, I derive many testable predictions of delay. I then take my model to the newly compiled GATT (Torquay) tariff negotiation data, which includes detailed (product-level) information of the timing and contents of countries’ (back-and-forth...

We analyze the design of optimal feed-in tariff schedules under production-based learning. We examine least cost policies in a simple two-period model that focuses on bringing down the levelized cost of renewable technologies to a predefined target under two well-known dynamics: learning-by-doing (LBD) and economies of scale (EOS). We show that, when the levelized cost reduction target is strin...

We look at privatization in a general equilibrium model of a small, tariff-distorted, open economy. There is a differentiated good produced by both private and public sector enterprises. A reduction in government production in order to cut losses from such production raises the returns to capital and increases the tariff revenue, which are welfare improving. However, privatization also leads to...

In this article, optimal two-part tariffs of a bi-directional telecommunications service are examined. Heterogeneous users are assumed to formulate social demand for the service. Two regimes of supplier are considered: monopoly and non-monopoly. In the latter, the supplier which enjoyed monopoly is faced with the entry of a competitive mpplier. Demand externalities which are conspicuous in tele...

flowing the uruguay round negotiations (1986-1994), the world trade system has evolved. on the basis of agreements of this round, world trade organization (wto) members have been obligated to decrease tariff obstacles, non-tariff restrains and trade supports. the use of trade liberalizing policies (tariff obstacles and non-tariff restrains) by members and observing countries has had significant...

In this study, the social welfare impacts of the interaction of Iranian rice import policies and Thai export policies are analyzed using a game theoretic approach in conjunction with econometric supply and demand models. The joint impacts of increasing the world price of rice, resulting from the export policies in Thailand along with changes in tariff rates in Iran, on social welfare are analyz...
