The Economics of Network Industries

Abstract: This book introduces upper-level undergraduates, graduate students, and researchers to the latest developments in network economics, one of the fastest-growing fields in all industrial organization. Network industries include the Internet, e-mail, telephony, computer hardware and software, music and video players, and service operations in the banking, legal, and airlines industries among many others. The work offers an overview of the subject matter as well as investigations about specific industries. It conveys the essential features of how strategic interactions between firms are affected by network activity, as well as covering social interaction and its influence on consumers' choices of products and services. Virtually no calculus is used in the text, and each chapter ends with a series of exercises and selected references. The text may be used for both one- and two-semester courses.

A bilingual advantage in task switching

Abstract: This study investigated the possibility that lifelong bilingualism may lead to enhanced efficiency in the ability to shift between mental sets. We compared the performance of monolingual and fluent bilingual college students in a task-switching paradigm. Bilinguals incurred reduced switching costs in the task-switching paradigm when compared with monolinguals, suggesting that lifelong experience in switching between languages may contribute to increased efficiency in the ability to shift flexibly between mental sets. On the other hand, bilinguals did not differ from monolinguals in the differential cost of performing mixed-task as opposed to single-task blocks. Together, these results indicate that bilingual advantages in executive function most likely extend beyond inhibition of competing responses, and encompass flexible mental shifting as well.

Testing Vocabulary Knowledge: Size, Strength, and Computer Adaptiveness.

Abstract: In this article, we describe the development and trial of a bilingual computerized test of vocabulary size, the number of words the learner knows, and strength, a combination of four aspects of knowledge of meaning that are assumed to constitute a hierarchy of difficulty: passive recognition (easiest), active recognition, passive recall, and active recall (hardest). The participants were 435 learners of English as a second language. We investigated whether the above hierarchy was valid and which strength modality correlated best with classroom language performance. Results showed that the hypothesized hierarchy was present at all word frequency levels, that passive recall was the best predictor of classroom language performance, and that growth in vocabulary knowledge was different for the different strength modalities.
