A new approach to explaining the existence of firms and markets, focusing on variability and coordination. It stands in contrast to the emphasis on transaction costs, and on monitoring and incentive structures, which are prominent in most of the modern literature in this field. This approach, called the variability approach, allows us to: show why both the need for communication and the coordination costs increase when the division of labor increases; explain why, while the firm relies on direction, the market does not; rigorously formulate the optimum divisionalization problem; better understand the relationship between technology and organization; show why the size' of the firm is limited; and to refine the analysis of whether the existence of a sharable input, or the presence of an external effect leads to the emergence of a firm. The book provides a wealth of insights for students and professionals in economics, business, law and organization.

The null subject has always been central to linguistic theory, because it tells us a great deal about the underlying structure of language in the human brain, and about the interface between syntax and semantics. Null subjects exist in languages such as Italian, Chinese, Russian and Greek where the subject of a sentence can be tacitly implied, and is understood from the context. In this systematic overview of null subjects, Jose A. Camacho reviews the key notions of null subject analyses over the past thirty years and encompasses the most recent findings and developments. He examines a balance of data on a range of languages with null subjects and also explores how adults and children acquire the properties of null subjects. This book provides an accessible and original account of null subject phenomena, ideal for graduate students and academic researchers interested in syntax, semantics and language typology.
