trade begets a myriad of trades aimed at dispersing risk. Convention would have
it that this kind of trade and the dispersal of risk contributes to financial instabil-
ity. But it is equally possible that the pricing of tiny gaps in the market and the
virtual and simultaneous spreading of risks across other traders and around the
world actually contributes to financial stability. Commonplace stories of global
financial instability do not take seriously the institutional management of risk
around the world on a 24-hour basis (see Clark and Thrift 2004 and compare
with Schoenberger 2000).
At the other end of the geographical scale, finance is increasingly the engine
driving urban structure and differentiation. For many years, urban development
was about the leverage of the public sector for private interest believing that the
former was the most important source of investment in urban infrastructure –
something that could not be priced or at least traded in the same way that
currencies and commodities can be traded. However, it is increasingly apparent
that governments are unable to provide the necessary volume and value of
capital for new investment in urban infrastructure let alone regeneration of invest-
ments that, in many cases, go back at least a century if not two centuries past. In
part, this is because of political constraints on the tax-raising capacity of national
and local governments. In part, this is also because governments are increasingly
caught between profound trade-offs such as expenditure on the education of the
young and expenditure on the health care of the elderly (Clark 2000). Political
constraints on tax-raising capacity have forced governments to rethink the virtues
of financial markets, while financial institutions have become better able at pricing
and distributing the risk associated with spatially fixed infrastructure investments.
Whatever the consequences for equity, financial markets are quietly re-making
modern cities (Babcock-Lumish and Clark 2005).
The nation-state as the banker of first call (smoothing the path of transactions,
local and global), a presumption that informs much of the debate about the role
of the state over the period 1950 to about 1980, is now a chimera. The nation-
state and its representatives at the local level face an ever-tightening fiscal squeeze
between competing generations’ claims on limited tax revenue. The role of the
state is as a regulator of financial markets and institutions, more focused upon
ensuring capital adequacy and adequate mechanisms of risk-management than
making up the difference where capital markets discriminate against certain groups
in favour of other groups (local and global).
