“Dear Tyler,

I read with obvious interest your post (and the paper itself) about the endogeneity of institutions. Leaving aside my issues with the IV literature, I decided to take the bait regarding Jeff Sachs’ challenge to, “Go back to 1960 and choose any measure of institutional quality you want. Then see how well it predicts cross-national growth since then.”

Ok, I will.

The Economic Freedom of the World (EFW) index was first published in the mid 1990s, and the first year of data is 1970. So I’ll have to start in 1970 instead of 1960.

Here is a regression with growth from 1970-2010 on the lhs, and EFW and GDP per capita in 1970 on the rhs.

Growth1970-2010 = -1.62 + 0.75*EFW1970 – 0.13* GDPPC1970 R^2=0.18

(2.90) (3.17)

This regression adds the change in EFW from 1970-1980 to the rhs.

Growth1970-2010 = -1.69 + 0.84*EFW1970 + 1.00*chEFW70-80 – 0.15*GDPPC1970 R^2=0.32

(3.54) (3.39) (3.86)

A one-unit higher EFW score in 1970 correlates to 0.84 percentage points in higher annual growth over the next 40 years. A one unit EFW score improvement during the first decade, 1970 to 1980, correlates to a 1.00 percentage point higher annual growth rate over the 40 years.

I don’t know if that satisfies Jeff Sachs’ challenge, but it works for me.

Looking forward, I’ve constructed a back-of-the-envelope indicator that combines each country’s EFW rating in 2000 and with its change from 2000-2010. The top 20 (combined highest level & most positive change) versus the bottom 20 (combine lowest level & most negative change) countries are:

Top 20 – Bottom 20

Hong Kong – Haiti

Romania – Cameroon

Rwanda – Senegal

Singapore – Guinea-Bissau

Bulgaria – Mali

Cyprus – Bolivia

Unit. Arab Em. – Algeria

Chile – Guyana

Mauritius – Gabon

Lithuania – Ecuador

Slovak Rep – Burundi

Albania – Cote d’Ivoire

Jordan – Chad

Switzerland – Togo

Bahamas – Congo, Rep. Of

Malta – Central Afr. Rep.

Taiwan – Argentina

Korea, South – Myanmar

Finland – Zimbabwe

Estonia – Venezuela

I’m willing to bet anyone $100 (up to 10 people) that the Top 20 group will outgrow the Bottom 20 group by at least 1 full percentage point per year (on average) over the the next 20 year period (2015-2035).
