Libertarian economist Jeff Miron discusses the economic impact of the federal government’s 2009 stimulus package on Tuesday, March 16, at 6:30 p.m. at the Plaza Branch, 4801 Main St.

Miron says because tax liabilities accompany any government spending program, last year’s stimulus package may not have expanded the output of the American economy, but instead simply redistributed the economy’s output.

Miron will explain how money was used and offer an alternative plan that he says would promote economic expansion in a presentation titled Obamanomics: Growing the Pie or Dividing the Pie?

Miron served as chairman of the Department of Economics at Boston University from 1992 to 1998 and currently teaches at Harvard University.
