* Document also calls for "Central World Bank"
* Condemns "idolatry of the market"

* Says reform should start under U.N. auspices (Recasts, adds more on document encouraging reform movements)
VATICAN CITY, Oct 24 - The Vatican called on Monday for sweeping reforms of the world economy and the creation of a ethical, global authority to regulate financial markets as demonstrations against corporate greed continued to spring up in major cities across the globe.
An 18-page document from the Vatican's Justice and Peace department said the financial downturn had revealed behaviours like "selfishness, collective greed and hoarding of goods on a great scale," adding that world economics needed an "ethic of solidarity" among rich and poor nations.
Urging Wall Street powerbrokers to examine the impact of their decisions on humanity, the Vatican called on those who wanted to change economic structures to "not be afraid to propose new ideas, even if they might destabilise pre-existing balances of power that prevail over the weakest."
The document was released as "Occupy Wall Street" protests this month sparked similar anti-capitalist movements around the world with demonstrators angry over government bailouts of big banks, corporate bonuses, and economic inequality.
The Vatican document was likely to be welcomed by the demonstrators who critics say lack clear objectives.
"The economic and financial crisis which the world is going through calls everyone, individuals and peoples, to examine in depth the principles and the cultural and moral values at the basis of social coexistence," said the Vatican document.
It condemned what it called "the idolatry of the market" as well as a "neo-liberal thinking" that it said looked exclusively at technical solutions to economic problems.
"If no solutions are found to the various forms of injustice, the negative effects that will follow on the social, political and economic level will be destined to create a climate of growing hostility and even violence, and ultimately undermine the very foundations of democratic institutions, even the ones considered most solid," it said.
The Vatican called for the establishment of "a supranational authority" with worldwide scope and "universal jurisdiction" to guide economic policies and decisions.
Such an authority should start with the United Nations as its reference point but later become independent and be endowed with the power to see to it that developed countries were not allowed to wield "excessive power over the weaker countries".
Asked at a news conference if the document could become a manifesto for the movement of the "indignant ones", who have criticised global economic policies, Cardinal Peter Turkson, head of the Vatican's Justice and Peace department, said:
"The people on Wall Street need to sit down and go through a process of discernment and see whether their role managing the finances of the world is actually serving the interests of humanity and the common good."
"We are calling for all these bodies and organisations to sit down and do a little bit of re-thinking."
One section of the document explained why the Vatican felt the reform of the global economy was necessary and called for specific reforms such as taxation of financial transactions.
"In economic and financial matters, the most significant difficulties come from the lack of an effective set of structures that can guarantee, in addition to a system of governance, a system of government for the economy and international finance," it said.
The Vatican said the International Monetary Fund (IMF) no longer had the power or ability to stabilise world finance by regulating overall money supply and it was no longer able to watch "over the amount of credit risk taken on by the system".
The world needed a "minimum shared body of rules to manage the global financial market" and "some form of global monetary management".
"In fact, one can see an emerging requirement for a body that will carry out the functions of a kind of 'central world bank' that regulates the flow and system of monetary exchanges similar to the national central banks," it said.
The document acknowledged that such change would take years to put into place and was bound to encounter resistance.
"Of course, this transformation will be made at the cost of a gradual, balanced transfer of a part of each nation's powers to a world authority and to regional authorities, but this is necessary at a time when the dynamism of human society and the economy and the progress of technology are transcending borders, which are in fact already very eroded in a globalised world."
