Explain the origins of the sovereign debt crisis in Europe and the consequences for the banking system and the real economy. the paper should start in a broad sense but should be narrowed down to a specific cause for the crisis and the consequences that came along with it. by narrowing it down more in depth analysis may be done in the paper to show understanding of the topic instead of writing a general paper that doesn’t allow for analysis of specific things. i need the paper to be done to a high standard.
