This paper emphasizes the different nature of cross border liberalization in network related services, such as telecoms, compared to liberalization in goods. In the presence of network externalities, it argues that if two disjoint country service networks involving a small and large country are...

This paper argues that the pursuit of special and differential treatments (SDT) by developing countries has hampered the liberalization of global service trade, which is one of the causes of the only slowing improving of service efficiency globally. We use value added per worker as a proxy of...

We explore the implications of trade liberalization in economies with State Owned enterprises (SOEs) and shirking. SOEs are modelled as controlled by the members of the enterprise who determine output and effort levels, while facing output prices and wage rates set by government. Enterprise...

We consider progressive geographical expansion of free trade zones within countries as a form of trade liberalization and compare observationally equivalent liberalization involving changes in the coverage of a free trade zone for a fixed tariff rate, and tariff reductions applying to all trade...

This paper considers liberalization of trade in both inter-temporal intermediation services and goods in a joint spatial-inter-temporal trade model. Joint multi-commodity spatial intertemporal models are not (to our knowledge) used in the trade literature as general comparative statics results...

We combine a model of combined inter-spatial and inter-temporal trade between countries recently used by Huang, Whalley and Zhang (2004) to analyze the merits of trade liberalization in services when goods trade is restricted with a model of foreign exchange rationing due to Clarete and Whalley...

We explore how outcomes of trade policy retaliation (Nash tariff games) are affected when trade simultaneously takes places geographically across countries and through time via financial intermediation. In such models deficits and surpluses in goods trade are endogenously determined, and...

We discuss a simple model of choices of joint consumption by a working couple who place maintenance of their marriage (relationship) above all else. Any proposal made by one partner seeking to provide maximal utility to the other so as to preserve the marriage, in the case where preferences of...

This paper analyses the ways in which product fragmentation (producing part of a product in one country, and a part elsewhere) can be used by multinational firms which have different productivity to serve the market abroad when product chains can be internationally and arbitrarily fragmented....

Numerical simulation exercises to analyze the impacts of potential changes in non-tariff policies commonly use ad valorem equivalent tariff treatment even though estimated impacts using explicit model representation and ad valorem equivalent treatments will differ. The difficulty for modellers...
