History Of Economic Growth Flashcards
Prod function
Y=AK to the alpha L to the 1-alpha
2 sources of growth
Proximate
Deep determinants

Growth hindrances
4 approaches to institutions
Efficiency approach-strong vs weak
5 theories of growth
Smithian
Solovian
Boserupian
Lewisonian
Schumpeterian
3 Tools needed to measure growth
GDP
PPP
Growth accounting
3 approaches to calculate GDP
Expenditure (Y=C+I+G+NX)
Income (Y=wL+rK+rents)
Production
3 price series/index’ and its purpose
Purpose to deflate nominal GDP to find real
Paasche index
Laspeyres index
Fisher ideal index
Problems with index numbers (5)
Choice of index
Choice of base year
Ignores changes in quality (focuses on price change)
Real value of options ignored
Representative baskets of goods?
E.g although nominal wages are deflated by CPI index to show purchasing power, basket of goods may vary for different wage levels (bottom 10% vs rich 10%)
Why use PPP
Exchange rates can’t find changes in real relative prices
2 types of PPP
Bilateral and multilateral
Bilateral notes and 1 negative.
Used in many 2 country studies where countries are similar.
Index does not satisfy transitivity.
Multilateral PPP
Used in many cross country studies.
DOES SATISFY TRANSITIVITY UNLIKE BILATERAL
Cobb Douglas function
Y=AK to the alpha x L to the 1-alpha
(A IS A CONSTANT)
Growth accounting for CD function
LN both sides to lnY=lnA+alphalnK + (1-alpha)lnL
Then differentiate.
(A is a constant)
Potential Issues with growth accounting (differentiation) to measure growth (2)
Choosing the production function!
Exponents may need constraining. E.g national income shares may change rapidly
Criticisms of growth accounting (3)
Shows rate of growth but not the actual level.
Results can be sensitive to period chosen
Doesn’t capture causes of growth.
E.g if technology shock (A changes), so output increases. K accumulates which increases output. But growth accounting only captures K accumulation.
Types of institutions (2)
Formal
Informal
Formal institutions (5)
Legal system (civil vs common law)
Political system (parliament vs presidential)
Economic system (capitalist vs socialist)
Education system
Healthcare (private vs public)
Why are institutions important for growth (3)
The proximate sources of growth (K,L,A) are influenced by them (deep determinants)
They impact transaction and transformation costs
They explain performance of different sectors, and different countries
Neoclassical assumption on institutions
They take institutions as given.
Issues in institutions
Property rights
Intellectual property rights-tech change, incentives to invest
Factor markets-efficiency in KL markets
Product markets-efficiency in goods markets
Government-constraints on executive and taxes
Commerce-ability to trade
Four approaches to institutions
Efficiency
Accidental
Cultural
Conflict
