Per the literature on transaction cost economics, capitalist contracts are not enforceable in situations of uncertainty. Yet, what exactly are the constraints that set in motion the demand for endogenous enforcement institutions?
The definition of uncertainty is negative, so we know what it is not and not what it is. Consequently contracts are not enforceable in the sense we don't' have theory prescribed mechanisms. From all this it follows that demand for such mechanisms set in motion should follow some kind of random walk.
