Research Process

The most surprising part of the research process so far is how little information there is out there on how economics has affected culture, yet there is a slew of sources on how culture is used to improve economics decision making. This has led to me spending a lot of time simply finding sources that are relevant to my research question. I already have the plan for my paper laid out; I just need to find a sufficient number of sources for my paper so I can move on and make an outline. I have tried using many different keyword combinations and databases, yet I still see the same pattern wherever I search. I am currently looking for different ways to research. Right now, I am looking at the references of papers that are slightly related to my research question in order to find sources that are related. I am having a little success with this method. I am worried that, after I start writing my paper, I will have to find sources to fill holes in my arguments, and I will have to go through the research process again where I will likely experience the same problems I have currently.
