Living Standards and Productivity
Living Standards and Productivity
•Income per capita is the most commonly used indicator of living standards.•In the national accounts Income=GDP•Much of the variation in GDP per capita is accounted for by GDP per
worker.
⇒Living standards are closely linked to production.
⇒This allows one to focus on properties of production.

Macroeconomics of Development L1: Introduction; Data and Facts
Proximate versus Fundamental Causes Differences in Living
Standards
•Proximate causes
◦Are some countries invest less in physical and human capital?
◦Are some countries fail to adopt new technologies and to organise production
efficiency?
•Fundamental causes◦Institutions (humanly-devised rules shaping incentives)
◦Geography (exogenous differences of environment)◦Culture (differences in beliefs, attitudes and preferences)
•Proximate causes help to identify fundamental causes
◦Development accounting can identify fundamental causes via identifying
proximate causes.

Development Accounting
Production
GDP per worker=F(Production Factors,Efficiency).
Development accounting
•uses cross-country data on output and inputs at one point in time,
•to assess the relative contribution of differences◦in factor quantities, and
◦in the efficiency with which those factors are used
to the cross-country differences in GDP per worker.

Usefulness...
Development Policy Design
•If differences in factors account primarily for differences in income per
capita,
⇒the goal of development policy is to engineer higher rates factor
accumulation.
•If differences in efficiency account primarily for differences in income per
capita,
⇒the goal of development policy is to engineer higher efficiency.
Efficiency
•Efficiency plays a very large role.•Experience suggests that this additional question is the hardest to crack.

Key steps in development accounting
1. F,2.3.We cannot measure efficiency directly: back out efficiency as residual
Efficiency
•Solow residual or TFP•Our measure of ignorance•one potentially promising research strategy is to try to “chip away” at this
residual by improving on steps (1) and (2),

Human capital
•What is human capital?
◦How we measure it?◦Average years of schooling? Or something else?•Economic concept of human capital
◦Human capital is the stock of skills embodied in workers which affects their
productivity, hence their wages on the labour market.
◦The effect of education and training can be measured on wages
Macroeconomics of Development L1: Introduction; Data and Facts
Development Accounting: Data
Human capital,h...Mincer regression
Mincer regression
•How much an additional year of education/training affects wages?•It is similar to the empirical micro literature (Mincer regressions)
log(wi) =κ+µSj+βXj+εj (2)
where
◦κ: intercept.
◦Sj: years of schooling of workeri;
◦µ: the increase in wages for an additional years of schooling.◦X: set of additional controls such as experience, location, gender, age, etc;◦β: the marginal effect of the controls.◦εi: error term.
•Results based on similar regression was first time published by Jacob
Mincer in 1974.

Linking human capital,h, to Mincerian regression
Human capital production function
•We have to make assumption about human capital production function
◦How years of schooling affects human capital?
◦Assume that
∂log(hj)
∂Sj
=µ
then human capital production function could be
hj= exp(µSj),
thus,f(S)is linear.
Macroeconomics of Development L1: Introduction; Data and Facts

Linking human capital,h, to Mincerian regression
Human capital production function
•Piece–wise linear returns to education instead of linear as above
f(Sj) =
0.134·Sj ifSj≤4
0.134·4+0.101·(Sj−4)if 4<Sj≤80.134·4+0.101·4+0.068·(Sj−8)if 8<Sj.

•The numbers for returns to schooling are based on a large scale
cross-country study applying to Mincerian regressions to country specific
micro data
•The returns to schooling numbers are averages across these country
regressions
