Economics and Science

In the New York times, Raj Chetty discusses the Nobel winners and economics as a science.  It is much better than this silly essay by Alex Rosenberg and Tyler Curtain, in which they argue that economics is not a science because it can't make predictions and then sugges that "an economic approach had much to contribute to the design and creative management of such institutions. Fixing bad economic and political institutions (concentrations of power, collusions and monopolies), improving good ones (like the Fed’s open-market operations), designing new ones (like electromagnetic bandwidth auctions), in the private and public sectors, are all attainable tasks of economic theory." How will economic theory help you to fix, improve or create institutions if it does not make predictions about the results of those changes?
