Predicting the Future of Prediction Markets
They make economic sense, but for some reason have never really taken off.
Prediction: Market uncertainty.

Sometimes economists are just flat-out wrong. According to economic theory, annuities and reverse mortgages should be very popular for managing risk and liquidity — yet both products struggle for mainstream acceptance. Another favorite of economists is prediction markets: contracts with payoffs contingent on some real-world event. Their future is also highly uncertain.
In essence, prediction markets let people “bet” on some feature of the economy, thereby creating a new financial derivative. A prediction market in gross domestic product, or perhaps in local rates of unemployment, could be a useful means of hedging risk. If you are afraid that GDP will fall, you could “short” GDP in a prediction market and thus protect your overall economic position, because your bet would pay out if GDP came in lower than expected.
