In the business world, people have talked about the role of serendipity or luck in a firm's success. Is there something similar for the success of a government's economic policy?
More specifically, are there any examples in history where a government intervention in the industry was held to be poorly-conceived or ill-informed from an economic perspective. For example, how the Ghanaian government used to instruct factories to be set up at unreasonable locations. But the intervention ended up unexpectedly benefiting the industry, e.g., lead to discovery of a new technology/a new market solution...?
