Essays on the Economics of Language and Language Policy by Alex Armstrong A thesis submitted to the Graduate Program in Economics in conformity with the requirements for the Degree of Doctor of Philosophy Queen(cid:146)s University Kingston, Ontario, Canada June 2013 Copyright c Alex Armstrong 2013 (cid:13) Abstract This thesis concerns the economic dimensions of second language knowledge and acquisition and the economic implications of language policies. The value of the ability to speak and understand a second language depends on the extent to which it enlarges one(cid:146)s communicative sphere which, in turn, depends on the language abilities of others. This implies that second language acquisition decisions are associated with strategic considerations and spillover e⁄ects. Consequently, the equilibrium distribution of language skills may not be socially e¢ cient and policy remedies may be called for. The (cid:133)rst essay of the thesis investigates the relationship between earnings, second language knowledgeandthedistributionoflanguageskillsinlocallabourmarketsinCanadausingcensus data. We estimate the elasticity of local language complementarity in earnings: a parameter that measures the importance of the linguistic environment in the earnings of the individual as well as the importance of language in the economy generally. The second essay addresses the e¢ ciency of second language acquisition decisions in a theo- reticalmodelwherebilingualismisrewardedwithahigherwagefortworeasons. First,language skills constitute a form of human capital in the sense that a worker(cid:146)s productivity is positively related to the proportion of the population with whom she shares a language. Second, language skills serve as a signal of productivity to employers. In general, the private and social bene(cid:133)ts of bilingualism do not align due to counteracting network and signalling welfare e⁄ects. The third essay concerns the role of language policy in improving social outcomes. A tax- subsidy system is considered under various assumptions about the ability of the government or planner to discriminate between individuals and groups. A Pareto improvement is possible if the government can condition the tax-subsidy system on language acquisition costs but not i otherwise. Thefourthessayconsiderstheoptimalprovisionofpublicserviceswhenindividuals(cid:146)e⁄ective consumption of the services depends on their pro(cid:133)ciency in the language they are provided in. The planner faces a trade-o⁄ between compensating minority language speakers for their lower wages and encouraging their integration by rewarding higher levels of dominant language pro(cid:133)ciency. ii Acknowledgements I am highly indebted to my supervisors, Robin Boadway and Charles Beach, for their advice and encouragement in preparing this thesis. I also bene(cid:133)ted from discussions with various other faculty members at Queen(cid:146)s University including Frank Lewis, James Bergin and Sumon Majumdar.
