, to mop up a crisis without paying due consideration to the massive social costs that it causes. it follows that central banks should pursue both price stability and financial stability in a balanced and harmonized way to promote macroeconomic soundness. the central bank must make full use of its expertise in evaluating macro financial risks as well. and when necessary, it should work to counter these risks jointly with the government and the financial supervisory authorities. as a next step, from a global perspective, we need to work to enhance policy effectiveness through collective policy actions involving governments and central banks around the world. the world economy has become highly integrated, and the complexity and inter - connectivity of economic and financial phenomena have greatly increased. it has therefore become tremendously difficult for any one central bank alone to either prevent a crisis or deal with its aftermath. in this light, the recent crisis has triggered a realization among policy - makers worldwide of just how important policy cooperation is between the government, the central bank and the financial supervisory authorities. and the building - up of networks to support this cooperation is of course equally important. as i am sure you are aware, the construction of global financial safety nets was adopted as an agenda for the seoul g20 summit as a korean initiative. this may be seen as one prominent example of a collective policy action, having the characteristic of the supply of global public goods. lastly, i would point out the need for identifying exactly what influence monetary policy will have in the transformed economic and financial environment following the crisis. this crisis has had a devastating impact on the balance sheets of households, corporations and financial institutions, not to mention the government ’ s fiscal position. the experience of the crisis and the tightening of global financial regulations will also cause vast shifts in economic agents ’ behavior. furthermore, the changes in global macroeconomic conditions after the us federal reserve ’ s recent additional quantitative easing are looming as new challenges for central banks ’ monetary policy. in order to cope with this new world economic regime, we will need to devise necessary countermeasures to deal with the possible changes in the monetary policy transmission channels and the limitation on policy effectiveness. particularly, given that changes are always and everywhere accompanied by uncertainty, we should endeavor even more strongly to heighten the predictability and credibility of our monetary policy. closing remarks fellow central bankers, i hope this seminar provides an opportunity for constructive discussions on how the central bank contributes to economic and financial stability within the macroprudential policy framework. it will also be good
