Not an unbiased source, but it brings together lots of studies (including a 2013 study by the University of Chicago:

Today, the most rigorous research shows little evidence of job reductions from a higher minimum wage. Indicative is a 2013 survey by the University of Chicago’s Booth School of Business in which leading economists agreed by a nearly 4 to 1 margin that the benefits of raising and indexing the minimum wage outweigh the costs.

Paul Krugman, Princeton University, February 2013: “Now, you might argue that even if the current minimum wage seems low, raising it would cost jobs. But there’s evidence on that question — lots and lots of evidence, because the minimum wage is one of the most studied issues in all of economics. U.S. experience, it turns out, offers many ‘natural experiments’ here, in which one state raises its minimum wage while others do not. And while there are dissenters, as there always are, the great preponderance of the evidence from these natural experiments points to little if any negative effect of minimum wage increases on employment.”

In Focus: Two Leading Studies on Minimum Wage and Job Growth

Study: Do Minimum Wages Really Reduce Teen Employment? (2011)

Summary: Examines every minimum wage increase in the United States over the past two decades—including increases that took place during protracted periods of high unemployment—and finds that raising the wage floor boosted incomes without reducing employment or slowing job creation. The research demonstrates how a body of previous research—one frequently relied on by business lobbyists who oppose minimum wage increases—inaccurately attributes declines in employment to increases in the minimum wage by failing to sufficiently account for critical economic factors.

Study: Minimum Wage Effects Across State Borders (2010)

Summary: Provides the most sophisticated study to date of the effects of increases in the minimum wage on job growth in the United States. Taking advantage of the fact that a record number of states raised their minimum wages during the 1990s and 2000s – creating scores of differing minimum wage rates across the country – the study compares employment levels among every pair of neighboring U.S. counties that had differing minimum wage levels at any time between 1990 and 2006 and finds that higher minimum wages did not reduce employment.

Lawrence Katz, Harvard University, April 2011: “This is one of the best and most convincing minimum wage papers in recent years.” (Source)

David Autor, Massachusetts Institute of Technology, April 2011: “The paper presents a fairly irrefutable case that state minimum wage laws do raise earnings in low wage jobs but do not reduce employment to any meaningful degree. Beyond this substantive contribution, the paper presents careful and compelling reanalysis of earlier work in this literature, showing that it appears biased by spatial correlation in employment trends.” (Source)
