Definitely something on income inequality! I didn't have time to do research on income inequality in Turkey or in other emerging economies in general. But it'd be nice to get some perspective. I've been reading a lot on that lately and my impression is you get different results depending on the way you slice and dice the data oh and on your political affiliation. But still the income inequality has been getting worse past 30 years in US and much of it is a result of tech innovation and education they say. Here's a good paper with tons of good stats and an interesting discussion with Robert Frank of Cornell.
Maybe you can write about unemployment, poverty, income inequality, i.e. things that people on the street care about.
i think you should write more in microeconomics.these are things that interest people and affect their lives.
