The general diffusion of any interesting idea is liable to generate a penumbra of popular misunderstandings and false assumptions, no matter how careful are those who promulgate that idea. The claim that increases in national income per head, beyond a certain minimum level, will give rise to no increase in human happiness is no less subject to this risk than any other challenging claim. In particular, it may come to be associated in popular thought with the notion that economists are bound to be surprised by such a claim, or even to regard it as a direct refutation of their most fundamental ideas. Any such notion is, of course, nonsense and ought to be exposed as such, both because truth is better than falsehood and because intelligent policy discussion about wellbeing can only be hindered by misperceptions of what economic theory does and does not have to say on this issue. The modest purpose of this chapter is thus, first, to recall what has been said about wellbeing and income by a number of major economists. Specifically, we shall consider some of the writings of Marshall, of Wicksteed, of Pigou, of Hicks and of de Van Graaff. Second, we shall turn to a brief consideration of some recent contributions to the literature on âthe economics of happinessâ.
Alfred Marshall (1842â1924)
Since Marshallâs Principles of Economics, which went through eight editions from 1890 to 1920, is unquestionably one of the founding works of modern mainstream economics, we begin by considering what Marshall had to say there about economics and wellbeing; for our purposes it will suffice to restrict our attention to the eighth edition (1920), without mentioning differences among the various editions.
Marshallâs Principles, naturally enough, is not a treatise on the ethics of the good life but that does not inhibit Marshall from giving many indications of what he took to be components of such a life and of how he took them to be related to economic matters. On the very first page of the text we read that the Principles is:
on the one side a study of wealth; and on the other, and more important side, a part of the study of man. For manâs character has been moulded by his every-day work, and the material resources which he thereby procures, more than by any other influence unless it be that of his religious ideals; and the two great forming agencies of the worldâs history have been the religious and the economic.
(1920: 1)
Character is not only shaped, Marshall claims, by the nature of oneâs work: âvery often the influence exerted on a personâs character by the amount of his income is hardly less, if it is less, than that exerted by the way in which it is earnedâ (2). Nevertheless, it âis true that in religion, in the family affections and in friendship, even the poor may find scope for many of those faculties which are the source of the highest happinessâ, even if the conditions of âextreme poverty ⌠tend to deaden the higher facultiesâ (2). We learn at once, then, that for Marshall âcharacterâ is of central importance (being related to both occupation and income) and that âthe highest happinessâ relates to religion, family affections and friendship. It is thus unlikely that the remaining 850 pages of the Principles will teach any simple doctrine that happiness increases if and only if real income per head increases. Leaving the question of character aside for the moment, we may dwell briefly on some of Marshallâs further hints as to the constituents of happiness. In the course of denying that economists are necessarily âadherents of the philosophical system of Hedonism or of Utilitarianismâ (17, n.1), Marshall hints (indirectly) that âtrue happiness is not to be had without self-respect, and that self-respect is to be had only on the condition of endeavouring so to live as to promote the progress of the human raceâ (ibid.). Somewhat less grandly, he speaks of âthe pursuit of science, literature and art for their own sakeâ and of âthe desire for excellence for its own sakeâ (88â89; this in connection with âwants and activitiesâ â see below). Moreover, âa personâs happiness often depend[s] more on his own physical, mental and moral health than on his external conditionsâ (133â134). Marshall can thus refer to âthose habits of body, mind, and spirit in which alone there is true happinessâ (136, emphasis added). The constituents of happiness are to be found in a personâs dispositions, not in their possessions.
What motivates people to act as they do? Marshall does not imagine that they always and everywhere pursue their true happiness! Yet their motivations are taken to be complex, even when they engage in economic activity. Thus:
What makes one course answer better than another, will not necessarily be a selfish gain, nor any material gain; and it will often have been argued that âthough this or that plan saved a little trouble or a little money, yet it was not fair to others,â and âit made one look mean,â or âit made one feel meanâ.
(21)
Considerations of trouble, money, fairness, reputation and self-respect can thus all function as motives. With respect to the earning of money, as a motive, it must be remembered that
Money is a means towards ends, and if the ends are noble, the desire for the means is not ignoble. [Money] is sought as a means to all kinds of ends, high as well as low, spiritual as well as material.
(22)
And if economics says much about earning money, âthis is so, not because money ⌠is regarded as the main aim of human effort [but because] it is the one convenient means of measuring human motive on a large scaleâ, pace Carlyle and Ruskin (ibid.). Earnings are, in any case, only one of various motives influencing a choice of occupation, others being the pleasure of the work itself, the delight in striving for achievement, social standing and class solidarity (23).
If the economist cannot always give full weight to the powerful motives of family affection, charity, duty and love of oneâs neighbour, this is ânot because they are not based on self-interestâ but because their action is not law-like. Were they governed by discernible laws, economists could and would take fuller account of them (24). Economics is by no means restricted to the consideration of self-regarding motives, âin fact the variety of motives [is] among the chief subjects with which we shall be occupied in this treatiseâ, Marshall writes (25). It is thus no surprise that he will have no truck with the idea of âeconomic manâ. For Marshall, economists:
deal with man as he is: not with an abstract or âeconomicâ man; but a man of flesh and blood. They deal with a man who is largely influenced by egoistic motives in his business life ⌠but who is also neither above vanity and recklessness, nor below delight in doing his work well for its own sake, or in sacrificing himself for the good of his family, his neighbours, or his country; a man who is not below the love of a virtuous life for its own sake.
(26â27)
Marshallâs âman as he isâ, we learn, âdesires not merely larger quantities of the things he has been accustomed to consume, but better qualities of those things; he desires a greater choice of things, and things that will satisfy new wants growing up within himâ. He comes to âdesire change for the sake of changeâ (86) and this leads Marshall âto remark with Senior that, âStrong as is the desire for variety, it is weak compared with the desire for distinctionââ (87). While Marshall tends to see such changing wants in a positive light (see below on âWants and activitiesâ), he is far from blind to their downside. He notes âthe Buddhist doctrine that ⌠real riches consist not in the abundance of goods but in the paucity of wantsâ (136) and remarks on his own account that âthe only direct effect of an increase in wants is to make people more miserable than beforeâ (690). He observes too that
after a time new riches often lose a great part of their charms. Partly this is the result of familiarity, which makes people cease to derive much pleasure from accustomed comforts and luxuries, though they suffer greater pain from their loss.
(135)
(Even in a much earlier work of 1879, Pure Theory of Foreign Trade and Domestic Value, Marshall had stressed that custom and habit can introduce irreversibilities into consumption behaviour.) How, then, could Marshall have been shocked by the claim that time-series income growth need not be correlated with happiness?
If Marshall was well aware that life is far from being exhausted by âeconomicâ considerations, he did not, of course, belittle them. He saw them as being of great importance, in that they influence the things that do ultimately matter. The âquestion [whether all can have a fair chance of a cultured life] cannot be fully answered by economic science. For the answer depends partly on the moral and political capabilities of human natureâ (4); but economics is nevertheless of great relevance to any answer. Any reader who has been unduly influenced by uncritical versions of the âeconomics and happinessâ thesis may then be surprised to find that Marshall goes straight on to assert that âthe bearing of economics on the higher wellbeing of man has been overlookedâ (ibid.); that is perhaps not a statement that Marshall would retain in a hypothetical 2010 edition of his Principles!
As Marshall draws closer to detailed, specific questions about the relation between measured economic magnitudes and wellbeing he seems to vacillate somewhat (the same is true of both Wicksteed and Pigou). On the one hand, he can write that âA shilling is the measure of less pleasure, or satisfaction of any kind, to a rich man than to a poor oneâ (19) and, again, that âa poundâs worth of satisfaction to an ordinary poor man is a much greater thing than a poundâs worth of satisfaction to an ordinary rich manâ (130). And he can ask quite explicitly âhow far the exchange value of any element of wealth, whether in collective or individual use, represents accurately the addition which it makes to happiness and wellbeingâ (85). Indeed he opens Book III, chapter VI with the words, âWe may now turn to consider how far the price which is actually paid for a thing represents the benefit that arises from its possessionâ (124). At the same time, however, he can suppose that âthis is not important in comparing two [large] groups composed of rich and poor in like proportionsâ (19, marginal summary and text) and that for large groups of people âthere is even some primâ facie probability that equal additions to their material resources will make about equal additions to the fullness of life, and the true progress of the human raceâ (20). This is no ill-considered chance remark on Marshallâs part, for he writes much later in the text (131):
On the whole however it happens that by far the greater number of the events with which economics deals, affect in about equal proportions all the different classes of society; so that if the money measures of the happiness caused by two events are equal, there is not in general any very great difference between the amounts of happiness in the two cases.
It will be clear here that Marshall is both recognizing the theoretical problem of principle and hoping that in practice it will not matter too much.
Even if two alternative ways of increasing income by the same amount will indeed change happiness by the same amount, questions remain as to the extent and permanence of that amount. We have already seen that Marshall was aware that familiarity can wear away an initial increase in happiness; he notes too that an increase in income can be misused, for example, through
that unwholesome desire for wealth as a means of display which has been the chief bane of the well-to-do classes in every civilized country ⌠it would be a gain if the moral sentiment of the community could induce people to avoid all sorts of display of individual wealth.
(136â137)
And he later refers to âa mere increase of artificial wants, among which perhaps the grosser wants may predominateâ (690). For Marshall, it would seem, there are bad as well as good ways of deploying increased command over resources.
Such considerations bring us back to Marshallâs concern with character and his related emphasis on activities or pursuits (as opposed to wants). These are rather delicate matters in that they are simultaneously of great importance to Marshall and yet difficult to pin down and to render at all precise. Only a brief outline can be attempted here and the interested reader is referred to Whitaker (1987, section II) and to Raffaelli et al. (2006: entries by Bateman, Coats and Raffaelli) for further discussion.
We noted above that the very first page of the Principles takes âmanâs characterâ to be of central importance and for Marshall it is not something fixed; it evolves, and progress â real progress â is essentially concerned with the uplifting of character. Wants (sometimes thought to lie at the heart of economic theory) are, for Marshall, only of secondary, albeit genuine importance. Thus:
even for the narrower uses of economic studies, it is important to know whether the desires which prevail are such as will help to build up a strong and righteous character. And in the broader uses of those studies ⌠the economist ⌠must concern himself with the ultimate aims of man, and take account of differences in real value between gratifications that [have] equal economic measures.
(17)
Since âhuman nature can be modified [and has been] very much even in a few generationsâ (752), one cannot assess economic events or policies while ignoring their effects on character. While earlier economists had ignored this, according to Marshall, âmodern economists keep constantly in mind the fact that [manâs character] is a product of the circumstances under which he has livedâ (764; this should surely have been made a prescriptive rather than a descriptive statement? I.S.).
What did Marshall regard as an improvement in character? Unsurprisingly, perhaps, he provides no neat, compact answer to this question but he certainly writes with approval of an increased willingness to postpone immediate gratification for the sake of future benefits, of prudence and self-control, of self-respect, of unselfishness and of willingness to act for the public good (680). He is similarly positive about:
an increase of intelligence and energy and self respect; leading to more care and judgement in expenditure, and to an avoidance of food and drink that gratify the appetite but afford no strength, and of ways of living that are unwholesome physically and morally.
(689)
Such qualities of character are linked not only to wants/desires but also to ways of acting, to activities and pursuits. While Marshall devotes Book III to âWants and their satisfactionâ (and no Book to activities), he insists that âwhile wants are the rulers of life among the lower animals, it is to changes in the forms of efforts and activities that we must turn when in search for the keynotes of the history of mankindâ (85). And he soon repeats and develops the point:
Speaking broadly therefore, although it is manâs wants in the earliest stages of his development that give rise to his activities, yet afterwards each new step upwards is to be regarded as the development of new activities giving rise to new wants, rather than of new wants giving rise to new activities.
(89)
The agents studied by Marshall, then, were poles apart from the caricature âeconomic manâ who is of a fixed nature and selfishly concerned only with acquiring material means to satisfy his given wants. His difficulty â and let no one underestimate its genuine nature â was that it was (and is) easier to speak of outputs, purchases and consumption than of ultimate goals, evolving human character, and so on. Marshall took the former to be related to the latter and therefore worthy of discussion but he could never have suggested that measured national income per head is of ultimate significance, or is even guaranteed always to promote that which is.
