Yale Economist and housing guru Robert Shiller says the economy is at a “tipping point” right now, and thinks there’s a “substantial probability” that we’ll see another recession in the next year. “I think the standard forecasting models would say no,” he tells The Wall Street Journal. “But we’re seeing a decline in confidence, we’re seeing a decline in home prices, seeing signs that encourage me to worry about that.” Shiller says he sees “animal spirits” flipping to the pessimistic side, but adds that it’s “still not clear” what will happen with the economy and the housing market. Shiller also talks about his ideas for reforming the U.S.’s financial system, and discusses whether Greece’s financial woes will topple the global financial system.
