The economy shapes both architecture and the ethics of its creators. A city focused only on profits may turn into nothing more than an Excel graph. However, the architects who design buildings without taking into account their future maintenance costs can create monsters that would pray on institutions’ budget and could slowly drive them into bankruptcy. The alternative economies which are being invented at times of crisis such as time banks, cashless exchange of goods and services, alternative currencies or expanding the informal economy, will surely influence both the architecture and organisation of the cities of tomorrow.
In many countries the shadow economy reaches up to 40% of the market share. The prognoses predict an ongoing increase in informal transfer of the capital. According to the Organisation for Economic Co-operation and Development almost half of all the working people in the world, which is around 1.8 billion people, are involved in the shadow economy. It is estimated that by 2020 this number will rise to two-thirds of all working people. More and more customers decide to go shopping at the street markets. This phenomenon is so common that many big corporations decide to launch their products also onto the stalls.
The traditional economy still denies the existence of informal economy because it is hard to examine and the boundary between the formal and informal circulation is rather blurry. Most of the economists ignore the influence it has on the world economy and describe it as a marginal or pathological phenomenon. The whole notion of a term ‘informal shadow economy’ is stigmatising. The journalist Robert Neuwirth in his book ‘Stealth of Nations. The Global Rise of the Informal Economy’ calls for a change in the language and finding a new name for the phenomenon. Instead of ‘shadow l economy’ or ‘black market’ he proposes a different name, ‘System D’.
The spontaneously developing shadow economy, called also the grey economy or System D will become an important element of global economy as well as of the city landscape in the 21st century. The street markets and space occupied by street vendors very often create local informal centres and a real alternative at the times of crisis. Together with the advance of System D we can expect to see the development of architecture and infrastructure related with it. Street stalls, collapsible tables, carts and other architectural forms of System D will have a more important role in our everyday life. As we change the language and the name of the alternative economy we should also coin a term of Shadow Architecture.
Shadow Architecture consists of objects, which were created without participation of any architect, as a side effect of the processes driven by the shadow economy. The awareness of Shadow Architecture has been denied by urban planners and architects although this kind of architecture has its regular users: petty traders and serious street vendors.
