We use a simplified Copeland and Taylor (1999) model, where the (developed) home country's pollution abatement technology is superior to that of the (less developed) foreign country. If there is no trade, workers will migrate from the foreign country to the home country. The foreign country gains from migration, but whether the home country gains or not depends on the abatement-technology gap and the magnitude of the coefficient of transboundary pollution. World welfare will increase under migration. If there is free trade in goods, international migration occurs when the home country specializes in the production of the environmentally sensitive good. In this case, migration will result in increased production of the manufactured good and increase the level of world pollution.","PeriodicalId":301337,"journal":{"name":"Social Responsibility in Production & Supply Chain Management eJournal","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127678708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model derived in this paper is rather simple. Nevertheless, it is able to produce a series of interesting results and useful insights. By means of the famous coconut parable, after Diamond (1982), we analyse whether a policy action had better choose to encourage (subsidise) clean productions, and let so the economy move towards a steady state equilibrium solution.","PeriodicalId":301337,"journal":{"name":"Social Responsibility in Production & Supply Chain Management eJournal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127003543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sethi","doi":"10.2139/ssrn.3494596","DOIUrl":"https://doi.org/10.2139/ssrn.3494596","url":null,"abstract":"This paper obtains decision and forecast horizons for undiscounted, continuous-time one-dimensional control systems. Some general conditions for the existence of horizons arising from the constraints imposed on the system are derived by using the optimality principle. These conditions are applicable to a variety of problems including production planning, machine maintenance, and cash management problems. Also derived are existence results that depend on the interplay between various costs involved in the context of a generalized production-inventory model. Horizons are obtained explicitly in some cases. The model includes as special cases, a version of the wheat-trading problem and some other inventory problems that have appeared in the literature. The paper concludes with an application of the results to a continuous-time concave production planning problem not yet treated in the horizon context.","PeriodicalId":301337,"journal":{"name":"Social Responsibility in Production & Supply Chain Management eJournal","volume":"79 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120907884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
