Language competition modeling and language policy evaluation

Abstract

Abstract In this paper, we present a framework for the analysis of effects of language policies on the competition between languages. At the core of this framework is a language competition model that takes into account four pivotal factors for the evolution of the linguistic composition of a society: intergenerational language transmission, formal language education, adult language learning and migration. In contrast to the majority of models available in the literature, our model operates with parameters that can be estimated from empirical socio-linguistic data. It allows the reconstruction of past and simulate future dynamics. Language policies can be modeled as changes in model parameters. Therefore, projections derived from the model can be utilized to compare the effects of different policy options. We use Basque and Spanish within the Basque Autonomous Community in Spain to illustrate the application of the model.
