To my knowledge the answer no. I think this is a good subject to be investigated.

There are few researches may help you in conducting your project. Please see the following:

The Influence of Zakat on Economic Growth and Welfare Society in Indonesia

Elleriz Aisha Khasandy, Rudy Badrudin

Very interesting topic, following...

Zakkat ensures the gap between the have and the have-not in an economy is to an extent reduced

https://www.dailysabah.com/columns/hatem-bazian/2018/04/28/zakat-trickle-up-economics

My scientific understanding supports the positive stimuli of Zakat on economic growth; country and community specific effects (on best practice) have still to be studied empirically.

How to measure Zakat?

Net assets method and/or net invested funds method as per computation.

Its interesting to see how a person like Bill Gates clearly suggests that simple "income tax" is not enough to ensure equality, but rather a tax on stored wealth is a better idea (the same idea of Zakat).

See his interview here. Part on taxing wealth starts around 2:30

Thanks!

I think that zakat increases money, develops it and disinfects it, and makes the distribution of money between the poor and the rich just and thus increases the movement of money and its cycle .

According to me, Zakat improves, develops and promotes the economic growth.

With best regards.

Since Zakat is a compulsory gift from wealth or excessive income (once a year) to poor people (as opposed to sadaka who is voluntary) by increasing their basket as a consumer, increasing their well-being by influencing their productivity growth in society and in a longer period of time reflects also on economic growth.

All the best!

Dear Rafiq Please see for example these two applied works:

The Impact of Zakat on Aggregate Consumption in Malaysia

Zakat expenditure and economic growth in the federal territory of Malaysia

If you have data available for the two mentioned variables for any country, you can built a proper model and estimate it using econometric techniques.

Wish you the best,

well, u can make a modele , making ZAKAT as private spending or a part of government spending (if your government gather all the zakat and spend it).

If zakat is well collected,and spent in a normal way.either from private or government. It can boost economy and brings about economic growth. And also in the long run, it will enhance economic development.

That needs to be measured where Zakat is collected. For now, Zakat has indirect effect on growth that is not officially identified in many places, countries etc.

Zakat can reduce unemployment rate in a country

Dr. Najeeb Zada from INCEIF has written about Zakat Re-Investment Trusts and its impacts. You can google him. His work is available on Springer too. Moreover, the Malaysians have written plenty on Zakat and its impacts. Likewise, some studies are available on Durham Online Thesis Repository.

Here an example of studies regarding your concern:

Daly, S., & Frikha, M. (2015). Islamic finance, a support to development and economi c growth: the principle of Zakat as an Example. Journal of Behavioural Economics, Finance, Entrepreneurship, Accounting and Transport, 3(1).
