It's all about the vision thing, or the lack of it, thinks Keio University economics professor Heizo Takenaka about the campaign for the Lower House election.

"It is obvious that simply continuing (expansionary) fiscal policy for another year could never do the economy any good," Takenaka said in an interview. "Political parties need vision. They have to present scenarios of how they will revitalize the economy.

"Some say economic recovery should come first at any cost and reconstruction of government finances later. But it is clear that both are important. The parties need to explain how both can be achieved," he said.
