I would argue that macro-economy is done with the wrong timespan. Much climate and weather forecast, there is a gap that is very hard, if not impossible to fill. Predicting the next semester is done quite alright. There are good economic models for long duration trend (50 years at least), though they are not used much because they are not very useful to invest as they do not have enough granularity. But the middle ground is just chaos.
