What are some potential research topics on accounting and finance? Any suggestions are much appreciated.
The sort of research topic you choose depends on the level of course you are enrolled in and your own skills and interests. For example, a research project for an MBA or PhD student would be quite different from one appropriate to a first or second year undergraduate.
The first rule for selecting a research topic is that the narrower the topic, the better chance you can do a good and thorough job of it. For example, "home mortgages" is such a broad topic as to be impossible to cover in any detail. Instead, you might ask a specific questions such as "within the state of Michigan, how do rates of defaults on home mortgages vary with population density? Do people in urban areas default at the same, greater, or lesser rates than people living in rural areas?"
One interesting project might be to look at how the development of the gig and service economies affect how we should calculate GDP. Another interesting area is the increase in the percentage of companies' values that are based on intangibles such as brand or intellectual property. While it is relatively easy to estimate the value of a block of buildings or bullion, it is far more difficult to value intangibles such as the prestige of a luxury brand.
The main method you should use for selecting a research topic is thinking about a research questions such as "what factors might affect wages or prices?" or "how do we assess the value of intellectual property?" and then find a focused data set that allows you to answer the question in detail for a specific sample.
Those are very general subjects, so there are literally hundreds of research areas and directions for you to choose from. You might consider Tax Accounting and how to avoid or survive an audit by the IRS. You could write about home finance and how most families deal with debt. The Finance Reform Act currently making its way through Congress affects the banking industry as well as personal finance and business accounting, so there are plenty of possibilities to pursue in that one topic alone. As a final suggestion, consider writing about the changes in the home mortgage market, why it is in such decline, and what may possibly revive that sector of the economy, or how ordinary citizens can take advantage of current rates and opportunities in that area.
It does seem as if the abuses of power in these fields would be a timely and researchable topic. the mortgage crisis, Wall Street, Small Business Administration...literally anything connected to the economic crash in the fall of 2008 (and anything since then, as well) would be interesting as well as insightful as you get ready to leave the world of education.
I think in today's economics a good research topic would be in the area of home mortgages. There is a lot of information out there and you could go several different ways with your research.
