In order to focus on the role of incomplete information in the allocation of resources, and to disentangle other effects (such as differences in R&D risks as in Saint-Paul (1997) and (2002)), we assume that all innovators can ensure the success of the innovation process by carrying-out some R&D activities that cost [bar.G] units of the final good
In this equation, [c.sub.m, t+1] denote a consumer's consumption of a final good
in a market economy in period t + 1.
To see why, observe that only in exceptional cases is the minimum efficient scale of producing an intermediate proportional to that of producing the final good
, so that the technologies are perfectly matched in terms of their outputs.
A large number of intermediate goods producers combine technology with labor inputs purchased from employment agencies to produce differentiated intermediate goods, which are then sold to final goods
where [omega] denotes the fraction of home intermediate goods that are used for the production of the home final good
and [theta] controls the elasticity of substitution between home and foreign intermediate goods.
(2) In this framework, final goods
producers need specialized intermediate inputs, and they enter an industry as either integrated or outsourcing enterprises, while suppliers of intermediate inputs enter as independent entities.
A function for the final good
production is set up with horizontally differentiated intermediate goods as input.
The direct effect of decreasing the foreign pollution tax will be a reduction in the price that the industrial consumers pays for the intermediate input ([mathematical expression not reproducible]), to produce the non-numeraire final good
. (26) As a result, intermediate input will have a lower price (for foreign industrial consumers), foreign demand for intermediate input will increase and the supply of the non-numeraire good will increase.
In the Melitz's (2003) model, firms employ only domestic labor and trade liberalization is modeled as a reduction in the variable cost of trading final goods
. The model solves for two cutoff levels of productivity: one determines the tradability of each good in the domestic market, whereas the other--larger than the first one--determines the tradability of each good in the export market.
The final Good

and China seems to imply that the countries are increasingly interdependent --a characterization that Sposi and Koech claim is unjustified because the manner in which trade is accounted for "fails to identify the contribution of different countries in the intermediate production of the final good
and is not representative of actual interdependence."
Social capital brings utility to individuals and it is also used in the accumulation of human capital and R&D, and in the production of the final good
. These features of the model are inspired by the empirical results stated above.
