For the litearture review first chnage the question based on the research you can find. this question should be more narrow by including:
which developing and/or developed countries?, what is your time scale (i.e., period of time)?, which theory will you be using to carry out your investigation?, which econometrics techniques?. these amendments to the question can be changed based on the research you do, i have attached a file that shows the assesment brief, aswell as a model example use that similar structure and use that for assistance, and include the synoptic table with the research you have done on the topic i have also attached a synoptic table on reaserch i have done before hand but feedback was given and i did not complete it that well have a look to make sure you dont do the same on the new synoptic table. if anything else is required let me know.
