Harcourt as an accountant economist

As the above quote indicates, Harcourt’s interest in accounting starts very early in his academic career, and in fact, he was first interested in the interface of economics and accounting long before he got engaged in the capital controversies which became his most celebrated work. As Geoff and Gay Meeks note, ‘Geoff’s interest dates from his doctoral research on the relationship between historic and current cost accounting – one of the first systematic analyses of the company accounts databank established by the National Institute (Harcourt Reference Harcourt1958)’ (Meeks & Meeks Reference Meeks, Meeks, Arestis, Palma and Sawyer1997, 91). And yet while his work on accounting and economics has been, according to Harcourt, an important part of his contribution, this aspect of his work remains relatively unexplored, and more so if we consider how it connects with the rest of his work or with broader post-Keynesian themes that Harcourt came to be a central contributor to for much of the second part of the twentieth century and the first two decades of the 21st.Footnote ¹

Since G.C. Harcourt’s passing in December 2021, a number of articles and remembrances note the nature of his contributions as a researcher, theorist, policy economist, and teacher among other things (see: Boianovsky Reference Boianovsky2022a; Cornis & Hawkins Reference Cornish and Hawkins2022a, Reference Cornish and Hawkins2022b; Kriesler Reference Kriesler2022; Russell Reference Russell2022).Footnote ² In this paper, we intend to review a significant part of his writings during the first twenty years of his academic life, from the early 1950s when he was still an undergraduate in the University of Melbourne to his Cambridge Ph.D. and the first years in Australia and the UK. Harcourt’s earliest publications show his interest in accounting quite vividly and include his first-ever book review (Harcourt Reference Harcourt1954), his undergraduate thesis titled The ‘Reserve’ Policy of Australian Companies during the Depression. A Study of Oligopoly in Australia over the period 1928 to 1934 (Harcourt Reference Harcourt1953), his masters’ thesis which was titled Pilot Survey of Personal Savings in Melbourne 1954 (Harcourt Reference Harcourt1955), and his Ph.D. thesis titled The finance of Investment Taxation, Depreciation, and Retained Profits in Selected United Kingdom Industries 1949–1953 (Harcourt Reference Harcourt1959a). In the 1960s, Harcourt continued to work on the allied topics of accounting and economic application making both theoretical and applied contributions to a variety of issues that came together, in a way, in 1969, with the publication with Robert Parker of the edited volume Readings in the Concept and Measurement of Income, a volume that became so important as a collection of readings that it was republished with a new preface by Geoffrey Whittington in 1986.

The present paper intends to make a contribution in understanding this part of G.C. Harcourt’s intellectual legacy. It intends first to offer a historical account of the development of Harcourt’s thought on the relationship between accountancy and economics, and second to offer an interpretation on how this work fits with his overall research agenda and remains an important contribution for the post-Keynesian approach, especially in the way Harcourt imagined it and practised it. This paper is an exploration of the accountancy theme of his research, but in its relation to the way that Harcourt practised post-Keynesian economics, and also what this tells us for post-Keynesian economics going forward.Footnote ³

The paper is structured as follows. In the next section, we discuss Harcourt’s early years from his undergraduate thesis to his PhD work and how this formed the basis of an important dimension of his research agenda in economics. In the third section, we discuss the development of that agenda in the decade 1959 to 1969 and explore how accounting conventions became an important feature in doing policy work in Harcourt’s footsteps. In the concluding section, we offer suggestions on a post-Keynesian view of the relationship of accounting and economics as it informs economic policy.

Geoff Harcourt in the 1950s: the foundations of his theoretical outlook and empirical methodology

It is interesting to note that from his undergraduate, masters’ and PhD theses, Harcourt had set himself the process that would come to define his later work, and by this, we mean the way he would tackle both theory and applied questions. His undergraduate thesis, completed when he was 22 years old, and submitted as part of the final examination for the Bachelor of Commerce degree in 1953, was titled: The ‘Reserve’ policy of Australian Companies during the Depression. A Study of Oligopoly in Australia over the period 1928–1934, and it starts almost mid-sentence with the following line:

In this, Harcourt’s first extended academic writing, we see not only his conversational style that would become his trademark but also the easiness by which he would put things in his own terms in order to clarify and focus what he thinks the problem is and what he wants to do to resolve it.Footnote ⁴ It also exhibits an important theme of his academic work, which is that theoretical questions are important because they have an impact on the real economy. A corollary of that broad statement is that Harcourt’s theoretical work is closely linked from the beginning to conventions that are determined by, and determine the policy environment and have real-world ramifications. It is in its capacity and uses as a convention that we should look into theory to see if it is fit for purpose or not. The line of the undergraduate thesis quoted above can be read in exactly these terms. The crux of the matter is, what is the financial provision that is ‘thought necessary’ before recording net income. The question may seem trivial, an easy applied question of little importance. How crucial could an accounting convention on how firms record net income be to their operation? Harcourt immediately notes that this decision has broad ramifications as it would, to some extent, determine consumption and therefore employment in the economy.

An important insight of the undergraduate thesis is Harcourt’s remark that an accounting convention of recording net income which may work well in a stationary economy becomes a drag in a growing one. He uses an example that he finds in the General Theory but develops it to a broader point. We quote at length:

Harcourt thinks this is not an isolated instance of net income accounting, but a pervasive feature of the modern economy. He writes a few pages later:

But a theoretical investigation of the problem of net income accounting is, in itself, incomplete, because without an idea of how big the problem is in the real economy it is impossible to say anything useful about it. Harcourt adds:

He adds a footnote, explaining that accounting values have a complex relation with economic values and this was sometimes not even fully appreciated by Keynes himself!Footnote ⁵

This criticism of Keynes and Keynesian theory remains an important open question. Are recorded values merely artificial book values of prevailing accounting techniques without any substantial economic significance and, by extension, recorded instances of hoarding are only a bookkeeping mirage? Or, as Keynes and later Keynesians assert, these accounting values are indications of hoarding from which we can infer shortfalls in effective demand?

Harcourt’s answer is to investigate in what form these reserves are held, and it remains a good answer in resolving some of these questions.Footnote ⁷ To this, Harcourt adds another complication in the mix, which is the fact that modern product markets are rarely approximated by the perfectly competitive model. Instead, oligopolistic markets and oligopolistic behaviour further complicates the picture, as now firms do not behave in the simple – almost static – profit maximising way that economic theory would find as natural for survival. Instead, the effort to dominate and control creates the conditions for price war, and price war is a situation that transcends the then-available tools of economic analysis. Harcourt writes:

Thus, outside the rarefied environment of a simplified competitive market,Footnote ⁸ firms exhibit complex behaviour and dynamic objectives. In this mix, the legal framework and the accounting rules are not inert compounds or irrelevant asides to competition, but central forces that shape the economic environment and determine the institutional framework in which firms operate.

Harcourt’s thesis is an impressive achievement by any standard for someone just starting their academic career. It not only contributes a complex set of questions but also attempts to do empirical analysis by looking into company accounts. The result of the empirical analysis is somewhat impressionistic and the conclusions of the thesis modest. Harcourt writes: ‘… the most I can claim to is this: that a rather minor point of Keynes’ original analysis has been shown, at least under Australian and oligopolistic conditions, to have been, not logically wrong, but factually misleading; and that by combining micro and macro analysis I have produced a slightly different way of looking at certain facts over the [Great] Depression years’ (Harcourt Reference Harcourt1953, 93). He stated only a page later: ‘I am conscious of the limitations of the empirical analysis and my reasoning powers’ (Harcourt Reference Harcourt1953, 94). And although the empirical methodology is limited for the broad set of questions he sets up to answer, the questions and the theoretical answers they give rise to remained foundational for his work over his lifetime.

That theoretical core may be summarised in the following fashion. If we dispense with the assumption of a static, almost ahistorical abstract conception of the firm, we observe that firms make decisions and operate in institutional environments in which certain conventions are observed – one of the most important is how they count net profits. If the environment in which firms operate is not the closed and unidimensional environment of perfect competition – where firms maximise profits and reduce production costs to the most efficient level with the market price policing the system, so that any firm that strays from this objective goes bankrupt – and instead we admit that firms operate in a complex environment where increasing profits is an ultimate but not necessarily an immediate objective, we realise that economic behaviour is not separable from the conventions that structure the market environment. These conventions, then, can have aggregate effects on employment, effective demand, and the overall stability of the system.Footnote ⁹ An immediate corollary of this broad agenda is that the way firms account for profits becomes an important factor in guiding firms’ behaviour and, at the policy level, government action when interfering in the market and especially when taxing profits. This, again, can have aggregate effects. An accounting convention that underestimates or overestimates profits for firms when, for example, there is inflation or deflation would produce different cumulative effects.

This research question, in broad terms, became the foundation of Harcourt’s Ph.D. thesis in Cambridge. The difference is that the Ph.D. thesis displayed the focus and clarity of a more mature work, eschewing some of the broad generalisations of the undergraduate thesis and analysing in clearer terms the problem of defining net income, coupled with more extensive and robust empirical analysis. Harcourt’s increasing ability to frame effectively empirical questions was an outcome of his master’s thesis, which developed a methodology applied to a pilot survey of family savings in Melbourne in 1954.

In his master’s thesis, he not only discussed the American and the UK experience by developing a sampling technique to understand consumption and saving behaviour of individuals from different parts of society but also advanced definitional issues for terms such as saving, income, and consumption, that are central to answering theoretical and empirical questions. What is revealing is that definitional and sampling design issues are not asides hidden in an appendix while presenting what empirical fundings he has collected but are the central contribution of the thesis. The remit of the assignment is to design a framework for data collecting that performed well on three principles: (1) it produced reasonably accurate results, (2) data collection could be performed in a reasonable time frame, and (3) the cost of running the scheme was not excessive. Furthermore, we find in his master’s thesis an important realisation that would be a defining feature of his later thinking: that data collecting is essentially story creation, as no data can be collected without some end use in mind. He writes revealingly:

This completes the three axes on which Harcourt’s master’s thesis was based, as necessary prerequisites for constructing useful data sets and doing empirical analysis: (1) discussions on the definitions of terms with reference to strengths and limitations,Footnote ¹⁰ (2) discussions on the sampling method and its strengths and drawbacks on capturing relevant data and, (3) the broad framing of this exercise by being aware that data are, ab initio, collected for a purpose, and the need to be aware of the framing that happens at the very beginning of this process and the limits of what can be said. There is, also, a fourth consideration, which is the ethical issues that arise as part of data collecting.Footnote ¹¹ This marrying of explorations of theoretical definitions with sampling technique issues, broad framing of the problem, and moral considerations is a key feature of Harcourt’s political economy approach of doing economics that became distinctive of his approach and has here its first full articulation.

In 1955, Harcourt arrives in Cambridge to start his PhD and write a thesis on profit accounting in UK industries, and the ramifications accounting conventions had both on the behaviour of firms and on economic policy. The main problem that Harcourt identifies is that companies, based on accounting conventions, would use historical cost when deriving net income (i.e. revenues from sales minus cost outlays), but historical cost (i.e. the cost of machinery at the date of purchase) would not necessarily equal the cost of replacing this machinery today. On top of that there is the problem of depreciation of machinery over time. Accountants use specific methods to account for the depreciating value of capital in the firm (usually straight-line method or reducing-balance method).Footnote ¹² Although these are based on standardised conventions, they may not reflect either the productivity changes of the machinery itself or the changing market valuation of used machines over their productive lives. Thus, economic costs – as measured by concepts such as current market replacement cost or opportunity cost – and accounting cost – as measured by accounting conventions that takes account of original historical cost and a specific shape of depreciation – would be out of joint. The problems this could cause are many and varied, not only by the firm taking economic decisions based on the wrong information (under-saving to replace capital due to using accounting cost instead of economic cost) but also by the government when designing taxation policies or other market interventions.

What mirrors Harcourt’s earlier undergraduate thesis is the understanding that this problem arises in a dynamic system and, not significantly (if at all) in a static one when there are no price changes. It makes sense to argue that in a static society even if accounting norms were imperfect in capturing depreciation rates of machinery empirically, by the very nature of being in a long run equilibrium static position, managers would have found out what they need to save in order to simply replicate their current machinery needs and would, in time, have rendered a problematic convention itself redundant if it survived at all. But as Alfred Marshall nicely pointed out, ‘the fact that the general conditions of life are not stationary is the source of many of the difficulties that are met with in applying economic doctrines to practical problems’ (Marshall 1961 (variorum edition vol. I), 347).

When there are dynamic factors – such as business cycles, growth, technological change, inflation/deflation periods, etc. – then a reversion to a simple heuristic of equating the concept of the ‘cost of production’ with what was actually paid when capital was bought runs into trouble, as a cleavage opens between what neoclassical economists see as costs in an evolving economy and what the accountants attempt to measure. For this reason, adjustments need to be made, which would be a way to approximate the current economic cost of capital goods and stocks. Harcourt estimates capital consumption at current replacement cost by multiplying the historical cost depreciation allowance of each fixed asset by an ‘inflation factor’ P _c /P _a where Pc is the current price of the asset and Pa stands for its price at the date of acquisition. For stocks that appreciate in value, the difference between the value of the stock over the year and the stock accumulation of the year was calculated.

It is, however, important to stress that these ‘adjustments’ are approximations themselves. Harcourt makes several assumptions to be able to approximate ‘better’ economic costs: first that firms want to keep their real capital intact – a behavioural assumption or a first approximation that makes the problem tractable. Then, the ‘assumptions that the productive efficiency of assets declines in the way implied by the method used to charge depreciation, and that the effective working lives of the asset have been investigated correctly’ (Harcourt, Reference Harcourt1959a, 12).Footnote ¹³ This means that Harcourt’s cost accounting is not an infallible guide to economic cost, but simply an improvement to the current accounting convention exactly because the economic environment has changed and requires new methods. As Harcourt points out, ‘this method is a practical way of estimating the opportunity costs of the fixed assets ‘used up’ in the year’s production’ (Harcourt Reference Harcourt1959a, 12).

Thus, concerning Harcourt’s first ten formative years in Melbourne and Cambridge we can say the following. Harcourt’s work on accounting not only opened up serious theoretical and practical questions on the link between economic theory and practice but developed tools on improving accounting conventions to deal better with the current economic and social problems, especially in relation to economic policy. He writes in his PhD thesis that:

In short, Harcourt noted that accounting conventions, by the very market participants that they were supposed to serve, were misguiding public policy and their own business decisions. More specifically, Harcourt’s interest in how to deal with inflation when firms use historical cost accounting would become a central concern in the decades that follow in the accounting literature and an important part of training to be an accountant.Footnote ¹⁴ Harcourt deals directly with the effects of cost-push inflation in one of his first publications (Harcourt Reference Harcourt1959b) where he combines ‘the models of profits and income under alternative pricing policies of Inflation and Company Finance [Mathews & Grant, Reference Mathews and Grant1958] and the model of The Accumulation of Capital [Robinson, Reference Robinson1956]’ (Harcourt Reference Harcourt1959b, 133).Footnote ¹⁵ He shows that with unemployment present, historical cost accounting and current cost accounting have different distributive and aggregate demand effects, with historical cost accounting having a greater expansionary effect in the economy.

Thus, Harcourt’s goal during this period was to understand the effects different accounting conventions had both at the firm decision level and in the macroeconomic environment. In general, he traced through the effects suggesting adjustments to the conventions to be able to perform their function better, being fully aware that his proposal was also an approximation, but an approximation that allied in a more efficient fashion economic thinking, accounting practice, and policy needs of his day. It is this mind frame that guided his published work on the links between accounting and economics over the next ten years, that we turn to next.

From 1959 to 1969: Harcourt’s accounting golden age

Harcourt’s first publications came during the time when he was still a graduate student (Barton & Harcourt Reference Barton and Harcourt1959; Harcourt Reference Harcourt1954, Reference Harcourt1958, Reference Harcourt1959b, Harcourt & Ironmonger Reference Harcourt and Ironmonger1956). In fact, in his Ph.D. thesis he notes that ‘an article based on chapter 5 was published in Accounting Research [Harcourt Reference Harcourt1958] and a note based on part of Chapter 7 was published in The Economic Record [Harcourt Reference Harcourt1959b]’ (Harcourt Reference Harcourt1959a, 1). The article with Duncan Ironmonger (Harcourt & Ironmonger Reference Harcourt and Ironmonger1956) relates to his work in his master’s thesis.

It was during the next decade that Harcourt wrote extensively on accounting and its relation to economics. He produced a number of publications (Harcourt Reference Harcourt1961, Reference Harcourt1962a, Reference Harcourt1963a, Reference Harcourt1964b, Reference Harcourt1966a, Reference Harcourt1966b, Reference Harcourt1967, Reference Harcourt1968a, Reference Harcourt1968b, Bennett & Harcourt Reference Bennett and Harcourt1960), but his article on the accountant in the golden age (Harcourt Reference Harcourt1965a) as well as a collection of essays on readings in the concept of measurement of income – together with Robert Henry (Bob) Parker (Parker and Harcourt Reference Harcourt1969), who was one of the most important academic accountants of his generation (see Nobles Reference Nobes2016) – stood out. By the late 1960s Harcourt started devoting increasingly his attention to the capital theory controversies (Harcourt Reference Harcourt1969) and the writing of his book (Harcourt Reference Harcourt1972) which made him famous.Footnote ¹⁶ It was in the mid-1960s that, according to Harcourt, he produced his second most well-known paper (Harcourt Reference Harcourt1965a), which was formative, to some extent, to his thoughts on empirical questions and policy.

Harcourt’s (Reference Harcourt1965a) article addressed a core question of his graduate investigations which was not tackled directly there. This is, would an accountant measure profit accurately, even under the extremely idealised conditions of a Golden Age, meaning a situation when ‘uncertainty is absent, expectations are fulfilled, and the rate of profit has an unambiguous meaning’ (Harcourt Reference Harcourt1965a, 310)? And by accurately he meant something simple but also very precise, that is, the ex post rate of return equals the ex ante one, or to put it in other terms, the convention the accountant is using proves to be yielding right predictions which are usually fulfilled in a stable economy. Harcourt finds this question not only to be important as a matter of pure theory but also crucial for empirical and policy issues. He notes that empirical estimates by economists use accounting figures, which would then be leading them astray: ‘if it can be shown that the measure is faulty even in the equilibrium conditions of a ‘Golden Age’, it is unlikely to prove a realistic measure in real world situations’ (Harcourt Reference Harcourt1965a, 311).Footnote ¹⁷

Harcourt’s main finding is that the ‘accountant’s measure of the rate of profit is misleading, even under ‘Golden Age’ conditions’ (Harcourt Reference Harcourt1965a, 311). He comes to this conclusion by investigating four distinct ‘Golden Ages’, first that of a stationary and a growing economy where capital is held as a physical asset, and second by introducing also financial assets held by firms. He then divides each case to four subcases where the decline of productivity of machines over their working life takes different shapes. The outcome of the exercise is a negative one both on how well the existing straight line and reducing-balance accounting depreciation rules approximate what the economist would see as the right value, but also because there is no simple general fix that would improve in general the accounting convention. Harcourt hoped that ‘some rough “rules of thumb” might be developed” and that these would allow accounting rates of profit to be adjusted for the lengths of life of machines, the patterns of quasi-rents, rates of growth, and the method of depreciation used. However, it is obvious from the calculations that the relationships involved are too complicated to allow this (Harcourt Reference Harcourt1965a, 324), which means that simple adjustments that could be practicable and offered as alternatives in general could not be devised even in golden age conditions.Footnote ¹⁸

This result signals a shift from his approach in his PhD thesis, where adjustments were used in empirical analysis even if it was clear that these were not general solutions to the problem. The 1965 result is more sobering as it shows that the problem is much deeper than a simple inefficiency of the conventions currently in use which can easily be fixed. And, as Harcourt notes in a revealing passage, in real conditions such situational comparisons as we can perform in Golden Ages would not even be possible. He writes ‘…the article is concerned with what would happen if he [the accountant] were to use his customary box of tools in ‘Golden Age’ conditions. In non-‘Golden Age’ situations, the only way of finding out whether expectations concerning rates of profit have been realised is to ask accountants – or use their tools’ (Harcourt Reference Harcourt1965a, 313). This realisation shows that even under the weaker assumption of the family of well-defined stable economies without any of the real-world complexities, general ‘better’ rules cannot be easily found, and that is before we even start extrapolating to the infinitely more complex condition of real markets.

What are we left with then? Simply, the negative result that the convention is problematic but that it cannot be generally improved upon? We think that Harcourt’s other articles during this period give us a provisional answer which has deep links with his Keynesian beliefs and thought. We are left with doing situational analysis and trying to find rules as imposed conventions given the data we have and can collect, the state of what we know and can imagine and the theoretical or policy question that we want to investigate. The mosaic of solutions and suggestions to policy questions is an outcome of this strategy of tackling problems. Harcourt’s different writings explore alternative trains of thought and analytical avenues without making any claim that these synthesise a picture that must conform to a general case. What connects these approaches is not the analytical conclusions but the tools that are used – different shapes of quasi-rents, different types of accounting rules, different kinds of capital structures, etc. All these abstract assumptions that economists customarily deploy are the tools to be used to answer specific questions that are posed in the theory or policy realms. This is how Harcourt saw economics in general. He writes, together with Karmel and Wallace, in the preface to their undergraduate textbook Economic Activity:

Examples of this approach may be found in Harcourt’s various publications during this period, especially when discussing specific public policy questions. In Harcourt (Reference Harcourt1966a), he mentally crosses the Iron Curtain to discuss how the measurement of the rate of profit affects the bonus scheme for managers in the Soviet Union. He shows that if you have two competing ways to produce a stream of goods – both of which have constant expected quasi-rents associated with the machines in each process, same lengths of life, same productive capacity per year, with one process having greater annual costs than the other – the more expensive (and therefore inefficient) process yields higher bonuses per unit of capital for the managers! This shows the kind of perverse incentives that can arise from the use of accounting conventions in a system and the real problems policy actions (even when well meaning) may give rise to.Footnote ¹⁹

Harcourt (Reference Harcourt1967) compares both sides of the Iron Curtain, by contrasting the rules that would indicate to the decision-makers in an enterprise which choice of technique to use.Footnote ²⁰ He finds that ‘in many instances, businessmen in the United Kingdom would install more capital-intensive techniques than would managers in the socialist countries with the same expectations and the same technology’ (Harcourt Reference Harcourt1967, 137–138). For Harcourt, this is the outcome of government policy and the accounting conventions that the decision-makers of the two blocks of countries were using when making decisions. In fact, he notes that in the UK academics and government economists were advocating for more use of the discount cash flow procedure which may result to a ‘switch to investment in less capital-intensive techniques than otherwise would have occurred’ (Harcourt Reference Harcourt1967, 138).

The question of public policy and investment-decision criteria for the UK is even more directly addressed in Harcourt (Reference Harcourt1968a), as he was invited to write specifically on policy recommendations for the UK and submit it to the Economic Journal given his earlier (Harcourt Reference Harcourt1967) article.Footnote ²¹ Together with Harcourt (Reference Harcourt1965a), this was his most formalised piece of analysis. Returning to the capitalist side of the Iron Curtain, Harcourt (Reference Harcourt1968a) discusses in more detail the policy ramifications of the UK’s government decision to ‘educate’ businessmen by encouraging them to adopt certain ‘correct’ rules of investment proposal’. (Harcourt Reference Harcourt1968a, 77; both educate and correct are in quotation marks indicating that Harcourt was using the language of the policy makers while not necessarily agreeing with it). He noted that successive British governments had implemented policies to encourage investment expenditure through fiscal initiatives. Harcourt placed the push for this new convention (the discounted cash flow) as part of the overall effort, that is to ‘result in the choice of more capital-intensive techniques than otherwise would have been the case’ (Harcourt Reference Harcourt1968a, 78). Thus, according to Harcourt, the British government saw the change of the accounting convention not only as a move towards more up-to-date practices but also as achieving specific capital formation objectives it finds desirable. However, as he shows in the EJ article, the combination of taxation and fiscal incentives is intricate and may produce, under certain conditions, the opposite to the desired effect. Thus, accounting rules and any institutional push for changing them should be investigated as part of a policy package that may include fiscal, monetary, and taxation instruments in the service of a specific economic outcome.Footnote ²² Institutional framing becomes part of policy design to achieve a set of objectives.

Harcourt’s second most important work on the link between accounting and economics, after his accountant and the golden age OEP article, is the collection Readings in the Concept and Measurement of Income that he edited with Parker in 1969. The introduction written by Parker and Harcourt is a tour de force not only for presenting the various readings and their interconnection but as an indication of how readers should be initiated in this literature and what conclusion to draw from it. The volume organises the articles in six sections that covers first definitions (I. concepts of income), then a discussion on these very definitions (II. income and the maintenance of capital intact), then III surveys on the economists’ views on income, followed by discussions on how to measure business income (IV. measurement of business income), problems of measurement and depreciation (V. depreciation), and finally the construction of national income and its issues (VI. national income accounting). This list shows that the volume starts from definitional issues, addresses problems of theory and measurement, and in the end presents new developments in measurement and accounting.

The reason for such a complex scheme is that ‘there is no reason to suppose that there is only one useful concept of income. Even a cursory glance at the contributions to this book suggests that there are many possible concepts’ (Parker & Harcourt Reference Parker and Harcourt1969, 4). This further illustrates how Harcourt generally worked in order to do economic policy work. He thought of the relevant framework, from definitions to abstract theorising, which was to some degree dictated by the policy question. This required substantial work by both the economist and the accountant, as well as a new mind frame to what they may be trained into. Parker and Harcourt acknowledged this problem while asking the following question:

It seems the reasons the professional accountant is against abandoning accounting cost is close to the reasons the professional mainstream economist is against abandoning the key neoclassical paradigm; these are they are not comfortable in dealing with deep uncertainty if they abandon the baseline model, and there is no single way forward to replace the current paradigm. But perhaps the answer is not to replace one monolithic construction with another but to start developing families of tools that do not give the same answer and then discuss and debate which tool is more useful for the policy or theory question we want to address. This means that we are also to accept another form of uncertainty, that which indicates that the tools we have and use for policy analysis and valuation are conventions that we have constructed because they are useful and give acceptable solutions to social problems. Objectivity in the use and application of tools, if it exists at all, comes from wider social acceptance of the methods and outcomes of this process, and the professional accountant as well as the professional economist can appeal to no higher authority than that. Harcourt would come back to that in his joint chapter with his Cambridge colleague Whittington (see Harcourt & Whittington Reference Harcourt, Whittington and Creedy1990), which may be regarded his last significant contribution to the relation between economics and accounting – appropriately written by an economist and an accountant, with special attention to the problems posed by inflation.
