    Sammanfattning : Despite being a pivotal topic over the past 50 years, the benefits and costs of internationalization are not well understood. A substantial body of research in international business, strategy, and general management is devoted to understanding firm internationalization and its connection to a firm’s financial performance; however, results are inconclusive.

    Sammanfattning : This thesis has three self-contained articles.Economic growth and trade in human capital: A salient empirical pattern in the East Asian “miracle” is a large increase in output and factor accumulation despite  only a modest increase in TFP. I develop and calibrate a model of growth and catch-up to provide a possible explanation. LÄS MER
