FACTBOX-Policies of Chile's main presidential candidates

Oct 26 (Reuters) - Chile's presidential election is shaping up to be a three-way race between a conservative billionaire, a former president from the ruling center-left coalition and an ex-film producer running as an independent.

The two traditional candidates in the Dec. 13 ballot, center-right businessman Sebastian Pinera and center-left former President Eduardo Frei, will likely keep the prudent fiscal policies that have made Chile's economy one of Latin America's most stable, analysts say.

But Pinera wants the private sector to take more leadership in stimulating the economy and creating new jobs, while Frei emphasizes the state's role but has not yet announced his economic policy platform.

Left-leaning independent Marco Enriquez-Ominami, 36, has broken away from the ruling coalition and advocates tighter state control over health, education, transport and social security. He would also raise taxes on the mining and corporate sectors and lower income tax.

The following are the main policies of the three main candidates:

SEBASTIAN PINERA:

* Maintain relaxed fiscal rules indefinitely by maintaining the current medium-term target for the fiscal surplus at zero percent of gross domestic product. In response to the global economic crisis, the government temporarily lowered its so-called "structural fiscal surplus" target from 0.5 percent of GDP to zero.

* Improve management of state companies like copper miner Codelco and energy company Enap.

* Allow private pension funds to hold a combined 20 percent of state copper giant Codelco.

* Give incentives to the private sector, particularly small and mid-sized companies, to create 1 million jobs between 2010-2014.

* Look at merging the regulators for the stock market and banking sector.

* Foster investment in alternative energy sources.

* Introduce legal rights for same-sex couples, but keep ban on gay marriage.

* Extend maternity leave to six months from three months.

EDUARDO FREI:

* Expand social welfare programs to include the middle class.
