Abstract
In many contexts across the globe, the scope and remit of planning is being limited. Much of the academic literature identifies this tendency as arising from a tension between planning as a state-regulatory activity and the tenets of neoliberalism – particularly free market competition. In this essay, we seek to explore the degree to which this perceived incompatibility between planning and the neoliberal order is genuinely real by running a thought experiment. We hope to show that thinking about the development process in this way points to alternative ways of imagining the scope and remit of planning – and how the normative principles at the core of the activity might be reconciled, or even extended, within the context of a neoliberal polity.
Introduction
In many contexts across the globe, the scope and remit of urban and environmental planning are being limited (Gunder, 2016; Gunn and Hillier, 2012; Holman et al., 2017; Hrelja, 2011; MacCullum and Hopkins, 2011; Mäntysalo and Saglie, 2010). As an activity that has statutory regulation at its core, it often grates against the now more or less fixed neoliberal orthodoxy that posits the market as locomotive of progress against bureaucracy as a brake on development (Brenner and Theodore, 2005; Fisher and Gilbert, 2013; Jones, 2012). Although the specific anatomy of the neoliberal order varies from nation to nation, some core similarities have been catalogued and planning’s corresponding incompatibility with these principles identified (for example, Lovering, 2009).
For some academics interested in making the case in favour of planning, corresponding attempts to diminish the professional activity to make way for the market have been understood as an ‘attack’ (Lord and Tewdwr-Jones, 2014). Others have highlighted the continuing public interest justification that spawned planning in the first place (Campbell, 2012). In some cases (Campbell and Fainstein, 2012), the defence of planning, quite correctly, points out that the environment (widely construed) is a very complex asset that is not well captured by those analyses of planning that categorise it as a restrictive drag on economic growth (Cheshire and Sheppard, 2005; Nathan and Overman, 2011). This point has been extended by research that has sought to investigate much more fully planning’s specific ‘added value’ (Adams and Tiesdell, 2010; Adams and Watkins, 2014). The net result of work in this vein has been to challenge the logic that real-estate markets would respond effectively to market signals if it was not for the planning system. Correspondingly, the argument has emerged that there may be value in thinking of planning as a ‘market maker’ (Lord and O’Brien, 2017) and that planning may be conceived as an important foil to the neoliberal hegemony rather than explicitly incompatible with it.
But what would this type of planning look like? Could we imagine ways in which a modernised planning might combine these ‘market making’ aspects with its normative ends and professional ethics: the public interest, social inclusion, environmental sustainability, balanced development?
An important strain in the literature would suggest not. A sustained body of work has emerged on the incompatibility of planning’s social and environmental goals with the core attributes of neoliberal capitalism. The result is that an earlier proposed ‘sustainability fix’ (While et al., 2004) has, following thoroughgoing empirical investigation, given way to scepticism that a balance can be struck (Bina, 2013; Georgeson et al., 2014; Gibbs and O’Neil, 2014; Krueger and Gibbs, 2007; O’Neil and Gibbs, 2016). For an area of public policy which is charged with precisely this task of taming the market, this question is particularly germane to planning. Although rarely confronted explicitly in the planning literature some, such as Campbell et al. (2014), have posed the question directly: ‘Is there space for better planning in a neoliberal world?’ (see also Legacy et al., 2016). At one remove, Holman et al.’s (2017) work has made a significant contribution through an exploration of the empirics of this question by looking at planning reform in England to explore the points of convergence and divergence between planning’s economic and ethical value(s).
In this paper, we hope to further this debate by exploring from first principles the relationship between how planning systems function at a human level and the outcomes they might entail. In this respect, our aim is to advance the literature on planning’s capacity to effect meaningful change in business decision making by exploring the intersection of ‘how real estate developers think’ (Brown, 2015) and how they might act and, correspondingly, any influence planning might have in this regard. In this respect, our contribution is to the nascent work that seeks to develop a ‘behavioural insights’ take on planning (Bond et al., 2016; Ferrari et al., 2011; Jackson and Watkins, 2008; Lord, 2009, 2012).
The development process: Rationality, belief and human behaviour
There is now a huge corpus of research on the development process, much of it inspired by various branches of economics. Perhaps, the best example of this crossover comes in the shape of transaction cost approaches that seek to understand the development process through the lens provided by the New Institutional Economics (Alexander, 1992, 2001; Lai et al., 2008; Webster, 2005). For adherents this framework provides a persuasive way of reading off outcomes from the governance arrangements and the interaction of the prevailing set of institutions (widely construed to include formal codes and informal norms of practice) that exist in a particular context. However, its post hoc vantage point and the primacy accorded to the rules and institutional players of the game – as opposed to the interpretation of those rules that result in the human behaviours of those who people the institutions (or act individually) – have meant that not all are convinced. Fischer’s (1977: 322) early unease remains relevant: Transaction costs have a well-deserved bad name as a theoretical device, because solutions to problems involving transaction costs are often sensitive to the assumed form of the costs, and because there is a suspicion that almost anything can be rationalized by invoking suitably specified transaction costs.
In those cases where game theory has been applied to planning-orientated questions, the focus has usually been on the specific microeconomics of urban transformation, particularly questions of land readjustment and compensation policy (Samsura et al., 2010, 2015). At one remove, others have shown the utility of using concepts from game theory to think about the dissemination of information and how this affects the strategies employed by all those who have any conceivable role in the development process (Kaza and Hopkins, 2009). The shared underlying logic of research in this vein suggests a fundamentally altered way of thinking about the economics of land-use planning more widely.
Alternative approaches to thinking about the development process have encompassed the use of ‘big data’ and econometric methods to simulate (aspects of) the production of the built environment (Brotchie et al., 1973; Gómez-Antonio and Hortas-Rico, 2016; Jiang et al., 2013; Reades, 2014), systems- and complexity theory-inspired approaches (Chadwick, 1978, 2nd edition; Hillier et al., 2016) and others that single out variations in agential power and the chronology of the process as holding explanatory power (Farías and Bender, 2010; Gar-On Yeh and Wu, 1996; Landis, 1995; Yigitcanlar and Teriman, 2015). At the intersection of these contributions sits an array or research which combines insights from consonant approaches – such as agent-based modelling, which seeks to marry the impulse to simulate with an appreciation of human agency (Batty, 2005). The promise of this approach is yet to be fully realised as the application of agent-based modelling to the development process is in its infancy (Baptista et al., 2016; Levy et al., 2016).
There are exciting developments in, and at the confluence of, all these approaches. However, although the various ways of thinking about the development process sketched out above offer rich insights into the specifics of the development process from place to place, we lack a thoroughgoing epistemological framework that would allow us to make part-whole connections across the, often, case-based empirical literature. Indeed, perhaps the single most important overriding message that emerges from the literature as a whole is that it makes little sense to talk of the development process when there are such huge variations between contexts: for example, the discretionary system of the UK, US zoning arrangements and Chinese statutory orchestration are systemically very distinct with huge variations in both legal framework and norms of practice. This point is well made in the classic statements of planning as a context-specific activity comprising multi-agent negotiations (and other communicative acts) (Forester, 1999; Healey, 1997). Therefore, to develop any kind of theoretically nuanced understanding of the development process that prevails in any particular context means engaging with the human psychology of decision making.
This presents a very specific challenge in two respects. Firstly, in theoretical terms, we have to be able to accommodate an understanding that participants in the development process may be acting on the basis of their beliefs about one another. By extension, these beliefs alone may have a significant bearing on individual (and collective) action and the outcomes that might result. Secondly, we need to be able to translate this understanding into empirical investigation. This would allow us to develop behavioural insights into the specifics of the ‘planning game’ that plays out in any particular context.
In this paper, we hope to address the first question: how could we theorise counterparty interaction in the development process to elucidate the importance of the beliefs that each forms about the other(s)? In so doing we hope to make the case that market intervention in the form of urban and environmental planning could have an effect on how developers think that in turn shapes how they act. We argue that this vision of planning as a market actor that regulates beliefs opens the door to imagining the sorts of planning system that could have a meaningful impact on business decision making. To do this, we use the medium of a simplified thought experiment. This approach has become the principal way of thinking about the underlying philosophical question – what we can know of other minds – and can be seen in classic examples such as the ‘brain in a jar’ (see also, Avramides, 2001; Ryle, 1949). The thought experiment allows us to explore from first principles under what circumstances we might come to have true, justified beliefs about cognition, behaviour and language in others. The specific nature of the thought experiment is a scenario – not always one that must closely mirror reality (as with the ‘brain in a jar’) – that provides a framing device to explore a specific question often pertaining to a fundamental principle of epistemology, metaphysics, logic or ethics. Thought experiments often take a greatly simplified or superficially contrived format to allow us to test the limits of some imagined state, for example, Hardin’s original iteration of the Tragedy of the Commons (and developments thereupon) serve perfectly to illustrate this point (Cole et al., 2014; Feeny et al., 1990; Hardin, 1968).
The medium of the thought experiment is well aligned to our objectives in this paper as we seek to explore from first principles the effects of belief on the development process, how beliefs might affect outcomes and how beliefs might be shaped through regulation. As established in the foregoing discussion, there cannot be said to be any singular real world with respect to the development process: there are myriad approaches taken that vary wildly from place to place. So, our aim is explicitly not to give a fine-grained rendering of how affecting beliefs might alter how the development process might work out in any specific location. We fully acknowledge that behaviours and the beliefs that motivate them are to some extent a reflection of the rules of the game established in a particular context. Instead, our aim is to consider the problem in the abstract through a simplified thought experiment that removes the issue of empirical context.
In what follows, we run a thought experiment that follows the well-known folk game ‘Going to the Party’ and in structural terms begins by mirroring the traditional rendering (for example see Perea, 2012). The purpose of the thought experiment is to explore how, even in a simplified scenario involving just two participants, a range of possible outcomes can be imagined dependent upon what each participant believes regarding the other. Each outcome is rational and reasonable: a set of potential ‘states of the world’ (Rasmussen, 2006). Which set of outcomes is preferable is wholly normative and would require prescription – an answer to the separate but not unrelated question of what should be the underpinning goals of a system designed to mediate competing ends vis a vis how our environment is governed. It is our contention in this paper that it is the value – and in the values – of a planning system to appreciate that a range of potential outcomes are possible, that they are belief-driven and that planning has the agency to seek to manage the beliefs that shape the process towards one of these end states.
Although we have explicitly and deliberately not sought to develop a thought experiment that exactly mirrors a specific case from the material world we have started, as with all thought experiments, from some principles that we are interested in exploring. Firstly, we seek to investigate how decision makers engaged in the development process might order their preferences over a range of potential sites; secondly, we seek to investigate how these preferences are affected by beliefs. More specifically, we hope to uncover how, what has long been argued to be a core, foundational feature of neoliberalism – competition (Wigger and Buch-Hansen, 2012, 2013) – might affect decision making. In this thought experiment, we set out to identify how the desire to gain an advantage by diminishing competition, a central principle of business strategy (Gunther-McGrath, 2013; Porter, 1979), might play out in the development process where aversion to competitive rivalry has a clearly spatial dynamic (Bulan et al., 2009; Xu and Yeh, 2005). Building from this we begin with three uncontroversial propositions that frame the thought experiment:
Developers prefer some sites to others. Developers prefer to limit competition within the context of their spatial preferences (defined under 1); Developers will formulate beliefs about one anothers’ spatial preferences that ultimately affect 1 and 2.
The thought experiment
Imagine a city that has four vacant sites for redevelopment: A, B, C and D. A is a ‘prime’ location; B and C incrementally less desirable and D, a deprived inner city neighbourhood, is deemed to have the least development potential as a profitable location. There are two main real-estate developers in our city run, respectively, by Mark and Cecilia. Mark has a well-defined set of preferences with respect to the development opportunities in the city: he favours Site A to Site B; B to C and C to D; however, the situation he dislikes most is when Cecilia competes with him for a site.
Mark’s preferences can be set out in tabular form:
Table 1 simply sets out Mark’s position with respect to how he ranks the desirability of acquiring each development opportunity; he derives most satisfaction from the acquisition of Site A and then transitively ranks the following three sites in descending order. However, a coincidental choice by Cecilia is the outcome he likes least: when Cecilia chooses to compete with him the desirability of that site diminishes to zero for Mark.
Mark’s preference set.
This ranked order of preferences (4,3,2,1,0) – utilities in the language of economics – represents Mark’s satisfaction with any of the possible outcomes of site acquisition; the full range of ‘states of the world’ that might prevail.
All other things being equal, it is clear that Mark’s preferred option is Site A. This is the best choice for Mark so long as he believes that Cecilia will make any choice other than Site A. If Mark believes that Cecilia has similar tastes to himself, and that she will likely pursue Site A too, the choice of Site B would be rational as the absence of spatial competition means this will yield a better outcome (expected utility, 3) compared to one where both Mark and Cecilia make the same choice for Site A (expected utility, 0).
How about Site C? If Mark believes that Cecilia will choose Site A clearly the only rational choice for Mark is Site B. But what if he believes Cecilia has a preference for one of the other sites? The strict ordering of the utilities would mean that Mark should go with his strongest preference, Site A, the one that yields him the greatest utility (4).
Is it the case, therefore, that there are no circumstances under which Site C or D could be a rational choice for Mark?
To this point, we have worked solely on the basis that Mark is certain in his belief about what Cecilia might do. However, beliefs rarely function in this way. Instead, we might believe to a certain extent that we can forecast what, for example, a competing property developer might do. For example, on reflection, Mark might arrive at the belief that he has a 60% expectation that Cecilia will choose Site A and a 40% probability that she will choose Site B. If Mark holds this belief about Cecilia’s actions, his expected utility can be summarised as a 60% chance that following his own strict preferences will result in he and Cecilia competing for the same site (Site A) the outcome of which would be totally unsatisfactory to Mark (utility, 0) and a 40% chance that Mark will succeed in obtaining Site A without having to compete with Cecilia (because she will have gone for Site B), thus realising his most preferred outcome and a utility of 4. This field of possibilities produced by Mark’s beliefs could be summarised as
By extension if Mark chooses Site B, he expects with probability 0.6 to have avoided competition with Cecilia and, therefore, to enjoy a utility of 3. Similarly he anticipates a 40% chance that they will have both opted for Site B, the presence of competition resulting in an expected utility of 0. Again, this could be summarised as
If Mark opts for Site C, he expects with certainty that he will not be competing with Cecilia as he expects with equivalent certainty that she will only be interested in Sites A and B. Looking again at Table 1, we see that the expected utility to Mark of choosing Site C is 2: greater than the expected utility resulting from his beliefs about Cecilia’s preferences with respect to either Site B (1.8) or Site A (1.6). Site D is still the least preferred of Mark’s non-competing options with an expected utility of 1. In summary, Mark now prefers C to B to A to D: a very different ranking to the one he started with before we formulated his beliefs as probabilistic expected utilities. We note that to make the point, we have intentionally kept the analysis as simple as possible. One may, however, argue that Mark’s belief have been arbitrarily specified without respecting the strategic interaction between the two players, Mark and Cecilia, and the consistency between beliefs and actions. To address this point, we demonstrate in Appendix 1 to this paper that Mark’s belief is consistent with Cecilia’s strategy and is part of a Bayesian Nash equilibrium in a game where Mark is uncertain about Cecilia’s preference regarding the four development sites.
Interpretation
This thought experiment illustrates how, even under the terms of a simplified game, rational choices made by market participants under competition are a function of their beliefs about others. It also illustrates how this may result in patterns of behaviour that run contra to what one might expect when beliefs are not considered: in the thought experiment, it is Mark’s beliefs about Cecilia that result in his optimal choice being what would otherwise be his third most preferred site.
So what should we make of this more widely? We can probably imagine scenarios where it may be in our collective societal interests that developers arrive at the conclusion that their less-preferred sites are the ones that they should pursue. This may be achieved by encouraging the necessary belief set on the part of competing developers to allow that conclusion to follow rationally. For regulatory planning this would mean helping to install within developers a belief profile consistent with the conclusion that investing in what would otherwise be their least-preferred sites, often inner city neighbourhoods which have been neglected, would be the logical thing to do. This would mean a greater, not lesser, role for planning. Moreover, it would mean a more economically active position for planning (Adams and Tiesdell, 2010): enhancing the desirability of C- and D-type sites by creating the perception that the right to develop might be more readily achieved over sites which, on first principles, would be more desirable to the developer but where development is less viable, because of competition and/or a diminished probability of consent. Alternatively, we could potentially conceive of more fundamental ways of achieving progressive outcomes through planning working with/harnessing neoliberalism’s competitive impulses. For example, bundling sites at either end of the spectrum could be arranged in such a way that the right to develop Site A was accompanied with the obligation to develop Site D. Such a strategy would be unequivocally behavioural-economic. Its outcomes might also be considered to give more socially preferable outcomes. Similar observations may be made with respect to environmentally more, over less, sustainable locations.
In the example in this paper, we have simply introduced two competing players, Mark and Cecilia, without any planning agency to mediate or coordinate their activities. Such an agency, a ‘market maker’ for land and property, would occupy a strategically vital role. It would be able to animate markets, shape their conditions and potentially, depending upon its power, reach and the skills of those who people it, affect the beliefs and, therefore, the decision making of developers. For example, in this thought experiment, we have not considered what might be entailed if Mark and Cecilia seek to cooperate and coordinate their actions in some way. A planning agency that had the power to diminish the likelihood of this outcome and maintain competitive market conditions or manipulate them, perhaps through encouraging competition for Sites A and B while diminishing the likelihood of competition for Sites C and D, would have a hugely significant bearing on the perceived desirability of sites. The corresponding effect such an agency might have on limiting developers’ choice sets and, critically, developers’ beliefs about one another’s preferences would also have profound effects on market conditions. Depending upon the ethical criteria by which such a system is held to account, it could potentially privilege ‘better’ outcomes in a neoliberal world in which competition is reified (Campbell et al., 2014).
Mark’s adjusted preference set.
Now, although the strict ranking remains the same, Mark favours Site A quite a bit more strongly than any other. Under this revised set of preferences, Site C can no longer be an optimal choice for Mark. He prefers Site A sufficiently more strongly that, with the same field of beliefs as before about Cecilia, his expected utilities become
The strength of Mark’s preference for Site A now means that despite his belief that Cecilia also favours this site and his very strong aversion to competition with Cecilia, he will favour the pursuit of this site to the others.
Extension and conclusions
Although this is only a simplified thought experiment, it serves to reveal some significant points regarding the importance of beliefs in shaping outcomes. Evidence from behavioural economics shows that if a belief is widely held and with sufficient conviction, we may identify the emergence of a normalising form of behaviour which results in ‘herding’. This formation of a commonly held belief extends far beyond the terms of the traditional neoclassical understanding of a wholly and perennially self-interested economic decision maker. For example, a connection may be explicitly traced between social pressures and expert opinion in creating and reinforcing the instinct to herd (Baddeley, 2013): highly relevant considerations with respect to real-estate transactions where social invocations to ‘get on the property ladder’ and mutually reinforcing expert opinions abound. Under conditions such as these, the establishment of herding has been understood as a collective psychological precursor to the irrational escalation of commitment common to many bubble markets where a premium is assigned to some asset(s) as a function of the prevailing belief that it is universally understood to be highly prized (see, for example, Roberts and Henneberry, 2007 on developers’ potentially irrational preference for capital cities). This creation of a socially normalised, limited ‘worldview’ (juxtaposed with the game theory understanding of multiple possible states of the world) seems to be a tendency common to humankind (Ostrom, 2014).
More widely, it is far from clear that the politically most popular neoclassical analyses of how real-estate markets function can be translated into realisable policy ends. For example, the view that building more residential units in areas of extreme demand, such as the New York/tri-state area or London/South East England, will stabilise or lower house prices through reconciling the mismatch between undersupply and excess(ive) demand is a potentially greatly oversimplified conclusion (see Marom and Carmon, 2015 for a review of housing policy in these two specific areas). The focus on the bricks and mortar of under supply at the expense of the behavioural psychology of demand in an over-heating market is in keeping with the ceteris paribus assumption common to neoclassical economics. But all things are not equal. Omitting the psychology of human economic decision makers produces very partial analyses that explain little of the irrationality of some real-estate market outcomes. Building many more new houses in locations where demand is strongest may do very little to lower or stabilise prices (assuming this is the true objective): not if the ‘Site A’ logic for, say, Greater London is sufficiently strong as a prevailing set of beliefs. We may simply build a great many very expensive new homes, probably to rather low standards – ‘rabbit hutches on postage stamps’ (Evans, 1991) – in areas of environmental jeopardy (in this English context particularly in relation to flood risk) that remain out of reach for many/most. From this perspective, the answer to resolving the affordable housing situation may require a fuller engagement with the beliefs and expectations of those who play the ‘planning game’ (Lord, 2012).
Mark’s final preference set.
To run the thought experiment through to its conclusion if Mark believes that Cecilia has a 50% probability of choosing Site A, a 30% preference for Site B and favours Site C to a degree of 20%, under this new set of preferences, every possible site becomes a potentially rational choice for Mark, including the otherwise least-preferred option, Site D. His expected utilities become
The order that Mark began with has been symmetrically reversed. His optimal choice is to go for the site he initially favoured least, Site D, because the fear of spatial competition with Cecilia is now greater relative to a less strongly ordered set of preferences. Surely this would be the end goal for any planning system: harnessing the competitive impulses of a neoliberal world to encourage better outcomes for areas that would otherwise be disadvantaged? Of course in practice, Mark’s beliefs may moderate over time. We may need to use Bayesian methods to understand how he updates his beliefs in light of information he gleans from Cecilia, for example, if commitment to a course of action is escalated as a result (Gilroy and Hantula, 2016). Equally, Cecilia may use signalling and screening strategies in an attempt to affect Mark’s beliefs about her. She may bluff, or double bluff; she may obfuscate; she may dissimulate and prevaricate. And so may Mark (see, Benz et al., 2016; Polnaszek and Stephens, 2013). We invite others to extend and develop the thought experiment such as we have done here and in Appendix 1 to this paper.
With so many moving parts, even in this greatly simplified thought experiment, there may be value in having a referee. An objective and impartial third party who can set and enforce the rules of the game explicitly to engineer behavioural outcomes may turn out to be a very important market participant. This would be particularly true if we are ever to make the Site Ds of the world – deprived neighbourhoods, complex but environmentally sustainable sites – locations where developers might rationally choose to invest. Conceiving of planning in this way suggests an alternative form of urban and environmental regulation that will entail a fuller dialogue with behavioural economics and ‘mechanism design’ (for example, Börgers, 2015). These schools of thought have had a profound effect on other aspects of public policy (for example, Halpern, 2015; Loewenstein, 2015; Madrian, 2014). Taking a cue from this literature and thinking again about beliefs, values and the epistemic underpinnings of how we animate the markets that produce the built environment may help us arrive at a clearer view regarding the role and value of planning in these markets.
