Hello! Is there any books or researches about competition for economy domination between Italian city-states? Well-known that Venice and Genua were two developed merchant republics, wich had a contest for influence in the mediterranean sea. I'd like to know about it more, in details. Рreferably including other states like Piza, Milano etc.
Just in case my suggestions below are altogether too esoteric, most of what you're interested in might be covered in Italy in the Age of the Renaissance by John M. Najemy
The thing is, it's difficult to find something that is simultaneously broad and detailed: The more you include (e.g., many Italian states) the less details are necessarily going to be included (same goes for individual themes: The more economic activities you include in a given study, the less detail you will find). But as long as we're exclusively talking about book recommendations for Italian economic history, you can consider the titles in the following list (all are originally written in English, which is itself a bit of a limiting factor as it means I've excluded Gino Luzzato's universal Storia Economica dell'Italia Medioevale, but in any case it should do. The titles are listed from most general to most esoteric based on my own recollection):
