The objective of this paper is to find the significant factors that crucially affect a firm's optimal transfer pricing policy. To achieve such a goal, it suffices to examine three minimalist vertical models: the first one contains a vertically integrated monopoly in both input and output...

This paper investigates a stepwise tax/subsidy structure on a monopoly practicing quantity discounts. It covers four tax/subsidy systems: uniform and non-uniform schemes, each under specific and ad valorem regimes. The effects of an exogenous change in a tier's tax rate on the optimal tier sizes...

This paper considers the optimal public ownership policy of an upstream firm which competes with a foreign private rival. Both firms supply a produced input to the domestic and foreign downstream firms that compete in an export market. The paper shows that complete privatization of the domestic...

This paper explores a monopolist's optimal multi-tier quantity-discount prices and shows that only the last tier's marginal cost is relevant in determining the tier prices and each tier's price is equal to its preceding tier's marginal revenue. An increase in total output is associated with...

This paper examines the optimal privatization policy in vertically related markets in which an upstream public firm competes with a foreign private rival in supplying a produced input to the domestic and foreign downstream firms in the domestic market. It shows that if the upstream public firm's...

In a symmetric model of free-trade blocs, the seemingly innocuous normalization rule by setting the world price of a given good as the numéraire will cause asymmetry in the Nash equilibrium. This paper presents a new symmetric tariff game approach and a new price normalization rule that are...

This paper identifies a new source of gains from trade from asset heterogeneity among firms. Under financial frictions, a firm's capital rental is constrained by its own assets. We show that, with or without productivity heterogeneity, trade openness or liberalization will always force the least...

We present a new tariff-game rule and a new numéraire rule in Krugman's celebrated model to form symmetric trading blocs. We hold that to maintain logical consistency in a world of symmetric trading blocs, an individual bloc should act on the actions of other individual external blocs in a...

This paper provides an overview of trade, environmental, and related public issues and policies. It discusses the pollution problem, the recent global warming trend, the attempts of world's various levels of institutions such as the UN, the WTO, regional, national, and other organizations to...
