What should I put in the Introduction as opposed to the Literature Review?
(In economics at least.)

Introduction (5 pages)

• start with some broader motivation or backgrund

– maybe a sentence or a paragraph at most

• quickly explain your problem/puzzle

– show not tell

– don't say your work is pathbreaking or the problem is interesting (arrogant)

• clearly, concisely explain what is novel

– crystal clear

• report key results 

– no hiding the punchline! 

• discuss implication

– what does it mean for public policy? for theory? etc

• Layout:

– a clear roadmap

– Section 1 does this. Section 2 does this. Section 3 etc...so they can find what they want. (This is the easiest paragraph to write)
