In the context of the Doha Development Round, the vast majority of computable general equilibrium studies examine agricultural trade led gains to developing countries, whilst European Union based studies are scarce and only one assessment exists in the case of Spain. This study also focuses on Spain, whilst developing the literature in two ways. Firstly, a more realistic representation of the a...

in this paper the trade restrictiveness of agricultural policies in iran was measured by the triindex for the nine major agricultural products including wheat, rice, barely, maize, soybean,meat (beef meat), soybean oil, sugar and banana over the period 1981 to 2007. the main resultsindicate that there is no trend in above index and high volatility especially in 2006 and 2007years due to conside...

Tariff bindings and administered protection are two characteristics of the WTO that are little understood. Tariff bindings place a ceiling on tariffs that is not always reached, while administered protection ensures that all sectors have access to some minimum import protection, effectively creating a floor for protection. How do these policies affect applied MFN tariff rates that are enacted t...

This paper studies two attempts that have been made to stimulate trade among developing countries by means of a trade-preferential system under the auspices of GATT and UNCTAD. It wil! be shown that these attempts have not been successful when measured in terms of the number of countries that have offered so-called "concessions" and the number of products for which substantial tariff cuts have ...

In this paper we are concerned with cuts in models of Samuel Buss' theories of bounded arithmetic, i.e. theories like $S_{2}^i$ and $T_{2}^i$. In correspondence with polynomial induction, we consider a rather new notion of cut that we call p-cut. We also consider small cuts, i.e. cuts that are bounded above by a small element. We study the basic properties of p-cuts and small cuts. In particula...

In many service industries, firms introduce three-part tariffs to replace or complement existing two-part tariffs. As opposed to two-part tariffs, three-part tariffs offer allowances, or “free” units of the service. Behavioral research suggests that the attributes of a pricing plan may affect behavior beyond their direct cost implications. There is evidence that customers value “free” units abo...

To analyze the effects on prices of simultaneous tariff reductions by multiple importing countries, we construct a simple three-country model where a good is produced by a monopolist with non-constant marginal cost and imported by two countries. We specifically compare two representative tariff-reduction formulas: the "fixed-amount" and the "uniform percentage" reductions. The uniform percentag...

We determine how the U.S. ethanol tax credit and import tariff affect the corn-ethanol-gasoline markets and how farm subsidies interact with these policies. We show how the ethanol tax credit and import tariff each uniquely affect the ethanol and gasoline prices. The ethanol import tariff alone increases the terms of trade in ethanol imports and corn exports, but decreases the terms of trade in...

Stockman and Dellas (1986) demonstrated that in the presence of complete international asset markets, the relative welfare implications of a small tariffare reversed from standard trade theory. This paper examines the robustness of that result to change in preference parameters and asset market structure. For nearly all values of substitution elasticity and risk aversion, the reversal remains. ...
