How to close the gap between non-Econ background and Macroeconomics I'm a first year PhD student with mathematical finance background, and am not quite familiar with all the assumptions/setup for macroeconomics. During study I found the math relatively easy but I'm having hard time to grasp the often critical relation between variables. For example capital market clearing implies that the total capital that firms have equal to the total assets that households have. First of all, I didn't even know there's a market clearing until I ask my TA, secondly, there are too many such assumptions I don't know. My professor would probably think it's too dumb to tell students about these because most of my classmates have an Econ background, but I don't and it's really killing me. Is there any good reference I can read, open courses I can watch that could help me with this? Given limited amount of time, I hope it won't take as much time as a full course. Thanks in advance.
Sorry if this sounds harsh, but: 

You need to start asking more. You're not stupid for asking questions - you're stupid for not asking questions. Be upfront about your different background and ask away. 

Of course you should try to research things by yourself, but a lot of assumptions are next to impossible to know or find out in a reasonable amount of time. I've got a 5 years of university economics - primarily in macro and I still struggle with assumptions. So, if you can't find it - ask! And ask your professor about some relevant books / articles.
