Iq-solow data

his study leverages an assortment of data. The working-age population (ages 15-64)
growth rate was obtained from the World Bank Open Data databases . For the
year 2014, the real GDP (Y) ,the working-age population (L) and the depreciation
rate δ were extracted from the Penn World Table 9.1 . The growth rate of tech-
nological progress g is assumed to be constant and equal to 1%,it corresponds to the
long-term growth rate of total factor productivity in the United States.Concurrently,
the average share of real investment (inclusive of government investment) was calculated based on PWT 9.1 data. The Regulatory
Quality Index, Corruption Index, Voice and Accountability Index, Political Stabili-
ty/No Violence Index, Government Effectiveness Index, and Rule of Law Index were
obtained from the Worldwide Governance Indicators (WGI) dataset, The biennial
frequency of the Worldwide Governance Indicators from 1996 to 2002 is unlikely to
significantly impact the study’s empirics. Governance indicators are generally stable
over short periods, especially in this case given the chosen samples, and the years with
biennial data form a small portion of the overall time frame of 1996 to 2014. Once
the dataset transitions to an annual frequency post-2002, this will further dilute any
potential influence of the initial biennial data.
