Question
For 5 minutes, please discuss with the person next to you Can you find an example of change in institutions in some country that accelerated economic growth / or a change in institutions that retarded growth? (please remember that such an impact can only be observed over a long time)
Basic growth story (1): mobilising production factors Roy F. Harrod (1939) Evsey Domar (1946)
Output is generated using capital and labour (production function), there is some substitution but law of variable proportions applies, so marginal product will diminish with substitution. Or even more extreme assumption: Labour has to be combined in a fixed proportion with capital; labour cannot be traded off for capital. Implications Increase in savings rate will increase growth rate (via investment in capital stock) Growth may be a temporary phenomenon as the growing amount of capital will lead to declining productivity of capital (e.g. John Maynard Keynes, echoing earlier prediction of Karl Marx who prophesied a downfall of capitalism in 19th century).

Assumptions
Labour and capital can be substituted for each other There are diminishing returns to capital, however this may be counterbalanced by productivity growth over time, driven by technological progress
(4) Introducing Institutions to Growth Theory (North, 1990): Institutional Environment and Incentives
Savings and investment: Why should I save unless I have an assurance that the financial intermediary between me and the investor will offer a return on my money (and unless the real value of savings is preserved over time)? Will private actors form a financial intermediary unless it can enter into contracts that would be honoured by borrowers (and savers) or can be enforced if not? Why should I invest in an environment of uncertainty?
Technology and human capital Why should I invest in better technology if others can imitate my technology costlessly once it is developed? Why should I invest in human capital if I can be forced to work as a serf?
Values
At the level that is deeper than both external and internal institutions we find (fundamental) values. Values are organising points for human preferences guiding choices and actions. They are accorded by most people most of the time as most important principles used in considering what is good or bad. Other, lower order, preferences are subordinated to them. Examples of such values may be freedom, justice, security or economic welfare. A communitys shared values support cohesion and motivate people to act consistent with institutions. Values are deeply anchored in the traditions and are not easily changed. They form part of the communitys identity. They may be tied to firmly held religious beliefs. Some difference in values may imply that the institutions that make the market economy may differ in detail across nations with implications for businesses (e.g. of developed countries: Japan v. US; see tutorials).
Readings
For this lecture please read Kasper et al., chapters 1 and 2.
Growth is different from development. Development is sustainabl. Growth can be temporary. Eg. Some reforms by a political party to stay in force. (dese are not good for long term). Groth is easier to measure and so considerd as an indicator.
