We describe a model of international, multidimensional policy coordination where countries can enter into selective and separate agreements with different partners along different policy dimensions. The model is used to examine the implications of negotiation tie-in - the requirement that...

We explore the links between migration of labour and location specific (urban) pollution, suggesting a sense in which pollution can be welfare improving. In a conventional Harris-Todaro model of urban-rural migration, individuals migrate so as to equate the expected urban wage (given a downward...

This paper uses computational techniques to assess whether or not various propositions that have been advanced as plausible in the literature on regional trade agreements may actually hold. The idea is to make probabilistic statements as to whether propositions of interest might hold, rather...

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 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...

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...
