Sources of economic growth around the world Economic policy and institutions matter for growth Democracy as an aspect of social capital Democracy is good for growth Cross-country patterns in data 164 countries, World Bank data Including political data on aspects of democracy Cross-country regressions social capitaldemocracy Interactions of human, real, financial, natural, and social capital, including democracy
GDP per capita GDP per capita (US$ at 1990 prices) Argentina and Sweden went hand in hand , and then grew apart free tradeliberal democracy income equality Sweden pursued free trade, liberal democracy, and income equality, and avoided high inflation Argentina did not Sweden 2.1% per year Argentina 1.0% per year = 3.1

King Faisal Listen to King Faisal of Saudi Arabia ( ), as quoted by his Oil Minister, Sheik Yamani: “In one generation we went from riding camels to riding Cadillacs. The way we are wasting money, I fear the next generation will be riding camels again.”
Lee Kwan Yew Lee Kwan Yew, founding father of Singapore ( ), would not have been surprised either: natural resources people education “I thought then that wealth depended mainly on the possession of territory and natural resources, whether fertile land..., or valuable minerals, or oil and gas. It was only after I had been in office for some years that I recognized... that the decisive factors were the people, their natural abilities, education and training.”
efficiencydiversificationgood for growth Democracy makes it easier to replace bad governments by better ones and for ideas to compete in the political arena, thus fostering efficiency and diversification, which is good for growth pressure groups bad for growth Democracy plays into the hands of pressure groups that abuse their power by swaying public policies and institutions in their favor, which is bad for growth Empirical question
Schumpeter (1942) “the democratic method is that institutional arrangement for arriving at political decisions in which individuals acquire the power to decide by means of a competitive struggle for the people’s vote.” Source of data Polity IV (Marshall and Jaggers, 2001) 21-point scale, from -10 to 10, extensive coverage of countries

-0.46 Inflation impedes growth Stabilization increases efficiency by reducing production distortions, uncertainty, inflation tax, and overvaluation
-0.46 Inflation impedes growth sound policies support rapid growth High inflation is a sure sign of lax fiscal and monetary policies, so sound policies support rapid growth
Null hypothesis Democracy is good for growth, and so are investment, education, health care, usw. Alternative hypothesis Democracy is not good for growth, or worse Not trying to demolish other potential explanations of growth Rather, trying to find a complementary role for democracy: add, not subtract Institutions, economic policies, and natural resources side by side
Theoretical framework Neoclassical vs. endogenous growth False contrast Empirically indistinguishable Endogenous growth, endogenous democracy Long run vs. medium term Medium term: Policy-relevant choice Forty years of data, Long run is irrelevant except as a benchmark
Empirical strategy 1)Levels of income vs. rates of growth 2)Recursive modeling vs. instruments 3)Averages vs. initial values of independent variables Prefer averages when available so as not to discard data after the initial period 4)Cross sections vs. panels Begin with cross sections, will add panels
Conditional convergence requires b > 0 < 1 One-to-one correspondence between parameters
Economic growth depends on the accumulation of capital and the efficiency with which it is used Five, or rather six, kinds of capital 1)Social 1)Social capital: democracy, corruption 2)Human 2)Human capital: education, fertility 3)Real 3)Real capital: investment 4)Financial 4)Financial capital: low inflation 5)Foreign 5)Foreign capital: openness -- ignore 6) Natural 6) Natural capital

with adequate natural resources Since the second world war it has become quite clear that rapid economic growth is available to those countries with adequate natural resources which make the effort to achieve it. W. Arthur Lewis (Accra, 1968)

Diversification is good for growth Economic diversification Economic diversification away from excessive reliance on natural resources Political diversification Political diversification away from narrowly based political elites toward full-fledged democracy Social and human capital are good for growth Democracy seems to make a difference Social insurance also makes a difference, as well as education and health care Judicious use of natural resources requires good institutions, including democracy Key to Norway’s successful oil management
The development effort required around the world includes a double diversification Economic diversification Away from agriculture and other natural- resource intensive activity into manufacturing (as in China) and services (as in India) P olitical diversification From dictatorship to democracy (as in Korea and Taiwan) These slides – and more! – can be viewed on my website:
