that turned Africans into commodities, for
example, can hardly be held up as an unmiti-
gated good (see Wolf, 1982). And the recent
for-profit trade in blood plasma from Haiti
to the USA and Europe reveals how despite
historic victories over slavery, its legacies
still provide a vampiric verso of economists’
unending odes to free trade in the present
(Farmer, 2006). But even putting such odious
examples aside, studies of the political and
economic geographies in which trade takes
place make universal claims about the good-
ness of trade seem absurd (Sheppard and
Barnes, 1990; Merrett, 1996; Porter and
Sheppard, 1998; Gilbert, 2005). One of the
major weaknesses of mainstream macroeco-
nomics is that it continually abstracts from
these geographies, mirroring but ignoring the
ways in which capitalist trading relations affix
prices to commodities that crystallize out their
abstract value (but see Fireside and Miller,
2005). All the focus is on the economic bene-
fits – never on the social, political and envir-
onmental ills that commodity production and
trade so often entails.
Going back to David Ricardo’s nineteenth-
century account ofcomparative advantage–
which abstracted from the political–economic
imperatives that were driving British manufac-
turers to seek new foreign markets for their prod-
ucts – abstractions such as ‘opportunity costs’
have continually led economists to obscure the
uneven international and personal power
relations in which trade takes place. Yet notwith-
standing endless economicmodellingdemon-
strating the supposed efficiencies of trade, and
notwithstanding the repeated emphasis on the
gains from trade in economics textbooks, the
geographical context of trade still matters – and
often reveals the losses from trade. This has
becomeespeciallyclearincontemporarydebates
over free trade and fair trade.
When the novelist Margaret Atwood joined
other Canadians in contesting the Canada–
USA Free Trade Agreement, she pointed
to the discursive power of free trade by under-
lining how it hinges on the positive association
of the word ‘free’, ‘as in free gift, free lunch, free
world and free speech’ (Atwood, 1993, p. 93).
Against this, Atwood argued that free trade in
fact represented the systematic straitjacketing
of Canada’s democratic autonomy and policy-
setting freedom. Many other critics in Canada
repeated the argument that free trade threa-
tened everything from public health services
to national development initiatives to food
safety to cultural creativity. Subsequent pro-
tests from Seattle to Singapore have made simi-
lar arguments against the world trade
organisation, underlining the many areas
of social, political and environmental policy-
making that are straitjacketed by trade laws
(Peet, 2003; Wallach and Woodall, 2004). At
the heart of these criticisms is a concern with
the ways in which free trade agreements create
systems of rule or state effects that, while grant-
ing TNCs quasi-constitutional rights, simul-
taneously undermine any sort of democratic
rights for the subject populations who want to
question and reform the new rules (Gill, 2003;
El Fisgo ́n, 2004; Sparke, Brown, Corva et al.,
2005). Based on these concerns and critiques,
diverse transnational groupings from the
world social forumto the Intercontinental
Caravan are converging to deliberate and de-
lineate diverse alternatives, including diverse
forms of fair trade (Featherstone, 2003; Rou-
tledge, 2003; Sparke, Brown, Corva et al.,
2005; Routledge, Nativel and Cumbers,
2006). Meanwhile, new work by feminist eco-
nomic geographers points hopefully (and des-
pite its capitalist government funding) towards
non-capitalist, extra-capitalist and, most ideal-
istically, post-capitalist forms of trade that is
‘free’ – frompoverty,patriarchyand corpor-
ate control (Gibson-Graham, 2006c: see also
feminist geographies). ms
tragedy of the commons A short-hand
for the popular assumption thatcollectivere-
source management– as opposed to private
or state-control ofresources- will inevitably
fail. The ‘tragedy of the commons’ was first
elaborated by Hardin (1968) as an extended
metaphorfor thinking about the need for so-
cial and institutional solutions to population
growth. Hardin sought to highlight how de-
cisions that are rational at the level of the indi-
vidual (about family size) can yield outcomes
that are far from optimal for society (what he
called the ‘population problem’). His aim was
to ‘exorcise the spirit of Adam Smith’ in demo-
graphy – that the pursuit of individual gain
would promote the public interest – and to
make the case for restrictions on ‘the freedom
to breed’. To make his point, Hardin asked
readers to ‘picture a pasture open to all’ upon
which herdsmen could stock as many cattle as
they saw fit. Each herder, he argued, would
further his or her self-interest by adding ani-
mals to the pasture, yet if all herders pursued
this strategy, the collective result would be
overgrazing: thus would ‘freedom in the com-
mons bring ruin to all’.
Hardin’s model has travelled widely within
academic and policy circles over the past four
