Freire, PhD

Economist & Data Analyst


What I am all about.

I'm Tiago, but you can call me James or 雅格. I am a published, award winning, quantitative economist, with 10+ years of experience in data analysis and 4+ years of experience in finance. I am an expert in using economic modeling and data science to analyze large, complex datasets.

My career intersects academia and industry. After completing my undergraduate degree in Economics, I started my career in finance, working for a European stock broker as a financial analyst and had the opportunity to feature in several TV interviews. To further my skills, I did a Master degree in the UK and earned a scholarhip to do my PhD in Economics in the US at Brown University, where I worked in John Vernon Henderson in a NSF and NIH funded project on the aftermath of the 2004 Indian Ocean Earthquake, that included field work in Aceh, Indonesia. In my thesis I analyzed big data, the Brazilian Census micro data for 1980, 1991 and 2000, using Stata and Matlab and I worked as a short-term consultant on Brazil at the World Bank. After completing my PhD I worked at the National University of Singapore, where I received several awards for my research, and moved for a better position at the Internationl Business School Suzhou of XJTLU in China teaching advanced macroeconomics and quantitative methods and published several papers on top journals such as The World Bank Economic Review , Annals of Regional Science and Food Policy .

In 2015 I returned to finance and joined a startup hedge fund in New York City., where I developed and coded in R, Python and SQL several of our analytical tools, such as our nowcasting/forecasting model, risk model, alternative data harvesting and alternative data analytics including machine learning company sales forecasting.

Wage Subsidies and the Labor Supply of Older People: Evidence from Singapore's Workfare Income Supplement Scheme
I currently completed and submitted to a journal a paper on the labour supply impact of a wage subsidy program for older workers. In particular, I looked at the impact of the Workfare Income Supplement Scheme in Singapore and found that the program increased the labour supply of women age 60 to 64 by 3.3 and 5.4 percentage points. This is the same paper I presented at the Asian Pacific Economies Seminar in May. You can find the paper on SSRN.
