Growth with Equity
In 88 growth spells:
•77 benefit the poorest fifth of the population
•changes in inequality were modest (roughly half small positive and half small negative).
Savings rates are uncorrelated with income or inequality. -50

Equity and Efficiency
Second Fundamental Theorem of Welfare Economics
Equity and efficiency can be separated.
Some Assumptions of the Theorem:
• Lump sum taxes and transfers• Perfect information, complete contracts, and complete markets• Perfect competition

Inequality and the Principal-Agent Problem
Inequality
“Principal” delegates use of assets to the “agent.”
If information is incomplete, this creates “agency costs.”

Example of Sharecropping
Sharecropping is an imperfect response to costly monitoring:
(i) Less effort
(ii) Less investment (and more depreciation)
(iii) Tenant may use low risk / low return techniques

Land Reform
Thus a theoretical rationale for land reform.
But, land reform often leads to:
• Falling output
• Eventual reconcentration of land
Why? And what can be done?

Increasing Output After Land Reform
Increasing access to capital
Credit constraints and high interest ratesUse of peer monitoring in micro-credit programs
Increasing development and dissemination of technology
Small farmers have an incentive to “free ride”Importance of extension programsComplementarity with educational investments

Sustaining Land Reform
If xt is the distribution at time t, the land distribution at t+1 will be:
xt+1 = A xt.
With fixed institutional arrangements, the distribution will generally return to its unique equilibrium land distribution (x*):
x* = A x*
![Page 10: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/10.jpg)
10
Endogenous Institutional Arrangements
If the transition depends on the distribution:
xt+1 = A(xt) xt
Then there may be multiple equilibrium land distributions:
x* = A(x*) x* and x** = A(x**) x**
![Page 11: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/11.jpg)
11
Institutions Depend on Government Policy
If A = A(G), then the equilibrium depends on government policy:
x* (G) = A(G) x* (G)

Problems with Sustaining Land Reform Through Direct Restrictions
1. They can often be avoided
2. Restricts use of land as collateral
3. Inhibits the response of labor to changing circumstances
![Page 13: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/13.jpg)

Sustaining Land Reform: Conclusions
1. Land reform can be self-fulfilling
2. Further distributional changes after land reform may be inevitable
3. Government policies (credit, technology, and education) can complement land reform
![Page 14: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/14.jpg)

Second Generation Reforms
Equity as a goal in itself
Equity as a means to greater efficiency
Examples: Land reformEducation
![Page 15: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/15.jpg)

Limitations of the “Washington Consensus”
Overly Narrow Instruments:
For instance,
(i) Competition as a complement to privatization and trade liberalization
(ii) Importance of legal and institutional development
(iii) Financial market regulation essential
![Page 16: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/16.jpg)
16
Limitations of the “Washington Consensus”
Overly Narrow Goals:
Development is not just increased GDP:
(i) Improved living standards(ii) Sustainable development(iii) Democratic development(iv) Equitable development
Development is a transformation of society
![Page 17: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/17.jpg)

Common Premises of Contrasting Visions of Development
Both the planning model of the 1960s and the “free market” model that followed assume:
(i) Developed and developing countries differ only in terms of the amount of capital and the efficiency of its intersectoral allocation
(ii) This problem warrants a technical “solution”
![Page 18: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/18.jpg)
18
The Importance of Government
(i) Successful development of the United States, and other economies, involved government.
(ii) Prior to active governments, societies did not develop.
(iii) Capitalist economies were highly volatile with many social/economic problems before active governments.

Puzzles of Development
Southern Italy has free trade with the North and same macroeconomic policies, but much slower growth
The Former Soviet Union became more market oriented, but output fell sharply. Destruction of social and organizational capital.
![Page 20: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/20.jpg)
20
Voice and Participation
If development is about the transformation of all of society, then reforms need to involve entire societies.
Evidence shows that participation and civil liberties help project implementation.
Importance of ownership: persuasion and self-determination.
Cannot get social/organizational capital from abroad.

The Relationship Between IFIs and Their Clients
Genuine change cannot be imposed
Policy advisers as interlocutors, facilitating change
Reforms require a sense of fairness -- about the policies and the process
![Page 22: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/22.jpg)

The Independence of the Central Bank
Macroeconomic decisions affect everyone.
These decisions are made under great uncertainty.
They are not just technical decisions for experts, but involve trade-offs and political judgements.
Thus the process matters. Many independent central banks, for instance, do not represent all of society, e.g. no workers on the governing boards.
![Page 23: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/23.jpg)

Key Questions for Monetary Policy
1. What is the NAIRU?
2. What are the costs of inflation?
3. Is there a precipice (i.e., does increased inflation lead to more inflation)?
4. Is the cost of reversing inflation high?
![Page 24: 1 Distribution, Efficiency and Voice: Designing the Second Generation of Reforms Joseph E. Stiglitz Senior Vice President and Chief Economist, The World](https://reader030.vdocuments.mx/reader030/viewer/2022032414/56649ef25503460f94c0465c/html5/thumbnails/24.jpg)

The Outcome of Central Bank Independence
1. Lower inflation
2. But, no improvement in growth, unemployment, or variability.
