Effects of Technology Transfers on the Provision of Public Goods

In this paper, we examine the viability ofcooperative policies oriented to the resolution oftransboundary pollution problems using the theory ofprivate provision of public goods in a two-countrymodel. We analyze the effects on economic welfare ofvoluntary technological transfers oriented to reducingthe emission of pollutants. Our analysis shows that when the atmosphere istaken as a pure public goods, ``a strong paradox'' emerges:the advanced country, in spite of the transfer, seesits economic welfare improved while the developingcountry sees it worsen. Moreover, if both a technicaland an income transfer occur, this paradox mightnot be solved. Furthermore, ``a paradoxicalimprovement'' occurs when the advanced country does nottake any policy towards the environment but thedeveloping country does: an improvement in the levelof technology in the developing country allows for anexpansion of the level of utility in both countries.On the other hand, in the case where the atmosphere istaken as an impure public goods, when both countriespursue an abatement policy, the transfer of technologyleads to an improvement in welfare in bothcountries.
