Over the past thirty years, the income gap between capital and labour has widened, a shift accompanied by an increase in dominant firms’ market power. To understand the underlying causes, our study integrates imperfect competition in both product and labour markets, revealing how different...

The use of proxy variables to control for unobservables when estimating a production function has become increasingly popular in empirical works in recent years. The present paper aims to contribute to this literature in three important ways. First, we provide a structured review of the...
