Evidence-first Islamic economics and personal finance
I’m Luqyan Tamanni, an economist and Certified Financial Planner® (CFP®) working on Islamic finance and household financial decisions in Indonesia.
Most family finance advice is either confident and unsourced, or rigorous and unreadable. This platform tries to be neither. I tackled questions that families and corporates actually face, such as how to deal with inflation, navigate geopolitical uncertainties, how the economy works, and how much debt is too much. Then I show what the research and official data say, where the evidence is weak, and where the law or shariah opinions set the boundaries.

Credibility checks
- Empirical claims rest on peer-reviewed journals ranked Q1 to Q3 by Scimago, cited with quartile and DOI.
- Legal claims rest on primary sources: statutes, regulations, regulator circulars, DSN-MUI fatwas, with effective dates.
- Figures come from official releases (Bank Indonesia, OJK, BPS, Ministry of Finance, World Bank), with series and release date named.
- Sharia positions show DSN-MUI and AAOIFI separately. My position is always in line with the official shariah body.
