|The Theory of the Firm
An overview of the economic mainstream
Firms are an ubiquitous feature of the economic landscape, much of the activity undertaken within an economy takes place within their boundaries. Lafontaine and Slade (2007: 629), for example, state that the "[d]ata on value added [ ... ] reveal that, in the United States, transactions that occur in firms are roughly equal in value to those that occur in markets". Micklethwait and Wooldridge (2003: xv) underscore the importance of firms by arguing that "[t]he most important organization in the world is the company: the basis of the prosperity of the West and the best hope for the future of the rest of the world". Given the size of the contribution made by firms to economic activity, employment, innovation, growth, income and wellbeing, having a sophisticated theoretical understanding of the nature and structure of firms is an crucial component of a proper understanding of how an economy functions.
The theoretical literature on the firm is diverse and growing, albeit from a small base, and no overview of the length presented here could possibly encompass all the different approaches that have been taken, across both time and the spectrum of economic thought, to the analysis of production and/or the firm. We therefore restrict our survey to, in the main, the major 'mainstream' approaches to the firm, in both their 'past' (pre-1970) and 'present' (post-1970) incarnations. The concentration on the mainstream theory is because these theories are, obviously, those which dominate the literature and aspects of the pre-1970 mainstream theory is still the most common, often the only, 'theory of the firm' taught to students. Few of the post-1970 theoretical advancements have made it, as yet, into the standard (in particular undergraduate) economics textbooks.While the intention here is to provide a concise, reasonably critical, yet readable survey primarily focussed on the contemporary advancements within the theoretical literature on the firm we also wish to help readers understand the evolution of the ideas that have resulted in these theories, to which end we consider, albeit briefly, the theoretical approaches of the pre-1970 literature as well as the approaches of the post-1970 period. Consideration of the history of the theory of the firm allows us to see the changes that have taken place with regard to economist's thinking on production and/or firms over the last 200 years or so. We will argue that over time a more sophisticated understanding of firms has begun to be developed, which has in turn led to the development of related areas such as the theory of privatisation, and we will look at some possible ways that the mainstream theory of the firm could evolve to continue this trend into the future.
Even for critics of the orthodoxy an appreciation of the mainstream theory is needed to understand the reasons for and the advantages/disadvantages of the non-standard approaches taken in the heterodox literature.The unique aspects of the book include its discussions of 1) the post-1970 contributions to the theory of the firm - the book offers an intuitive introduction to the contemporary theories of the firm as well as simple formal models of the most important contributions to the literature; 2) the integration of the theory of the entrepreneur with the theory of the firm; and 3) the theory of privatisation. Such a combination of topics is not covered in most other texts.
An extensive bibliography is provided to guide readers to further reading on topics of interest and as a starting point for reading on material not covered directly in the text. See, for example, Chapter note 3, page 6, for information on other surveys of the mainstream theory and the pertinent empirical evidence, in addition to coverage of some applications and extensions of the mainstream approaches to the firm. For another example see Chapter note 6, page 7, for references that provide, along with their own bibliographies, a starting point for reading on the heterodox literature.It has been assumed that reader will have been exposed to the standard introductory/intermediate 'textbook' treatment of the 'firm' and thus little time need be spent on a discussion of the details of this material.
In terms of the mathematics required we try to follow the advice of A. W. Zotoff: "In spite of the maxim, "Il ne s'agit pas de faire lire, mais de faire penser," we think that mathematical problems should not be given to economists to solve, and that mathematical economics should be treated as simply as possible, with all results worked out in detail" (Zotoff 1923: 115). We thus attempt to provide as much detail as is needed for a senior undergraduate to follow any mathematical argument relatively easily.This book is of great interest to those who study history of economic thought, organisational economics and industrial economics.

Errors so far:The numbering of equations is wrong. The numbering system should be "page number.equation number". This mean that equation 65.2 should be the second equation on page 65. But it is not. For most equations in the book the numbering system turns out to be "page number −1.equation number" so that equation 65.2 actually appears on page 66. In addition there are some pages with equations numbered by two different page numbers included on them. Page 82 has numbers equation numbers 81.1, 82.1, 82.2 and 82.3 on it. Page 86 contains equations 85.1 and 86.1.
p. 5 footnote 1: Quotes around the first appearance of firm should be single quote marks while the quotes around the second use of firm should be double quotes.p. 8 footnote 7: the quote marks around entrepreneur and undertaker in the sentence beginning “In his 1931 …” should be single quote.
p. 8 footnote 8: the quotes around uncertainty and risk in the sentence beginning “On the nature of …” should be single quotes.p. 53: section heading 3.2: delete single quotes around The Nature of the firm.
p.73: reference to Holmstrom and Tirole (1989) should be Holmstrom and Tirole (1991).
p. 85: second line from the top "vale" should be "value".p. 96: Math aside: reu_B(z,G; rho) should be replaced by u_B(z,G; rho).
p. 131: last line on the page "nothelp" should be replaced by "not help".p. 135: 5th line from the top "plus revenue" should be replaced by "plus revenue $(p\times q)$". (This is the tex code that gives the desired result, which is roughly (p x q))
p. 135: Figure 135.1: "Firm's revenue" should be replaced by "Payment to firm". On the vertical axis "p" should be added opposite where the horizontal dashed line ends at the vertical axis.
