Is there an infrastructure crisis in America? Would we really need $1.5 trillion in new spending to solve it? Dr. Ed Glaeser joins us to break down the good, the bad, and the ugly of the new infrastructure bill, and help debunk the magical thinking among Democrats that if we just spend massive amounts of money on rail lines, we'll revitalize stagnant economies.

Ed Glaeser is a senior fellow at the Manhattan Institute, a contributing editor of City Journal, and the Fred and Eleanor Glimp Professor of Economics at Harvard University, where he has taught since 1992. He regularly teaches microeconomic theory and, occasionally, urban and public economics.

Glaeser's research focuses on the determinants of city growth and the role of cities as centers of idea transmission. He has published dozens of papers on cities, economic growth, and law and economics. Glaeser is the author of Cities, Agglomeration, and Spatial Equilibrium (2008); Triumph of the City: How Our Greatest Invention Makes Us Richer, Smarter, Greener, Healthier, and Happier (2012); and coauthor of Rethinking Federal Housing Policy: How to Make Housing Plentiful and Affordable (2008). He holds a Ph.D. from the University of Chicago.
