We construct a Schumpeterian growth model of a common market with following properties. Households can stay as workers or become researchers at some cost. Workers are employed in production and researchers in R&D. Workers are unionized. A larger common market means a wider variety of products and more intensive goods market competition. The main findings are as follows. If the common market is able to carry out extensive labour market reforms, then it should accept new members as long as this increases consumption per capita. 如果没有广泛的改革是可行的,那么common market should respond to excessive union power by accepting new members, which increases competition in the product market. |
