There certainly are consistent answers in economics. But they tend to read more like safety rules than active policy measures. E.G. Regulatory price fixing below market rates will create shortages. The runaway printing of money will simply cause the value of money to fall relative to commodities (inflation). Questions such as "What is leaving the EU going to cost the UK economy?" Or "When will we have the next recession and what will cause it?" Are much more nuanced questions. Mostly because markets are predictive, and any new information is immediately incorporated into those predictions. It is like asking "what sort of software failure is going to cause the next major computer breach?" If we knew the answer, we would fix it and our prediction would be immediately invalidated. Computer experts were predicting the rise of cryptolocker variants when Heartbleed & Shellshock happened. Then you had everyone auditing all their OSS stacks, when out of left field we get big news from Intel on Meltdown/Spectre.
