4Chapter 22 Just Distribution
- Why is the distribution of wealth and income a
contentious issue? - (1) people who are too poor will not care about
sustainability. Why not? - (2) people who are excessively rich consume large
amounts of finite resources - (3) if we care about sustainability, we must care
about intergenerational distribution - (4) we know the economic system cannot grow
forever on a finite planet - So if distribution is so important, why is it so
contentious? - Eco-eco in general distribution policies should
not take away from people what they have earned
through their own efforts and abilities. However, - Who created those values?
- Is a fair price being paid?
- And what of the impacts of unequal distribution?
5Distribution
- Focuses on
- Income
- Wealth
- Market goods
- Nonmarket goods
- What are some policies designed to achieve a more
just distribution?
6Caps on Income and Wealth
- What right does the state have to take what
someone has earned? - What is the other perspective?
- 1st law of thermodynamics
- What is the harm of accumulating wealth for
status? - (1) How do people show their status?
- (2) How is status measured? relative to others
result zero sum game - some policies progressive consumption tax.
Progressive income tax. Progressive wealth tax. - How is consumption a negative externality? Can
you explain how a progressive consumption tax
could even make the wealthy better off? - (be sure to read Box 22-1)
7Minimum income
- How to guarantee a minimum income? What is the
objective? - Hmm those with the lowest income, typically
spend the highest percentages of those incomes on
consumption.. Positive-feedback loop? - Maximize production or maximize utility?
- People have benefited from past contributions to
productivity. How? - What are those policies?
8Minimum income some policies
- 1. welfare programs
- 2. unemployment insurance for the unemployed
- 3. minimum wages (living wages?) and negative
income taxes for the employed - Are these the best approaches to ending poverty
for either society or the recipients of such
transfers? What are other ways? - First equal opportunity in education, job
access, and job advancement - Second equal entitlements to wealth created by
nature and by society, regardless of business
ability of individual
9Distributing returns from the factors of
production
- Remember 4 sources of income wages, profits,
interest, and rent - Wages return to labor
- Profits returns to entrepreneurship
- Interest return to capital
- Rent return to land and other natural resources
- Most efforts at distributing income focus on
returns to labor - But greatest disparities in income are the result
of the other factors of production - So how do we distribute the returns to capital
and the returns to natural capital?
10- Poverty, Growth and Income Distribution in
Lebanon - Heba El Laithy. Khalid Abu-Ismail. Kamal Hamdan
- http//www.ipc-undp.org/pub/IPCCountryStudy13.pdf
- This Country Study is based on a full national
report that is the first to draw a profile of
poverty in Lebanon based on money-metric poverty
measurements of household expenditures. The
report provides a comprehensive overview of the
characteristics of the poor and estimates the
extent of poverty and the degree of inequality in
the country. It finds that nearly 28 per cent of
the Lebanese population can be considered poor
and eight per cent can be considered extremely
poor. However, the most important finding of the
report is that regional disparities are striking.
For example, whereas poverty rates are
insignificant in the capitol, Beirut, they are
very high in the Northern city of Akkar. In
general, the North governorate has been lagging
behind the rest of the country and thus its
poverty rate has become high. Levels of poverty
are above-average in the South but are not as
severe as expected. There are three other major
results that have notable implications for a
poverty-reduction programme in Lebanon. First,
with few exceptions, measures of human
deprivation, such as that provided by an
Unsatisfied Basic Needs methodology, are
generally commensurate with those for
money-metric measures based on household
expenditures. Second, the projected cost of
halving extreme poverty is very modest, namely, a
mere fraction of the cost of the country?s large
external debt obligations. However, such a cost
would rise dramatically if inequality were to
worsen (i.e., if future growth were anti-poor).
Also, the cost of reducing overall poverty would
be substantially higher. Third, the poor are
heavily concentrated among the unemployed and
among unskilled workers, with the latter
concentrated in sectors such as agriculture and
construction. This places a priority on a
broad-based, inclusive pattern of economic growth
that could stimulate employment in such sectors.
Based on such findings, the report concentrates
on providing general policy recommendations on
issues of directing public expenditures to poor
households. One of its major recommendations is
to concentrate on channelling resources to poor
regions below the governorate level, such as to
four ?strata? where two-thirds of the poor in
Lebanon are concentrated. However, the report
notes that macroeconomic policies, particularly
fiscal policies, will have to be redesigned to
mobilize the reources necessary to finance the
increases in public expenditures on the social
safety nets and public investment in social
services that should be part of a major
poverty-reduction programme.
11Distributing returns to capital
- Financial capital highly concentrated both
within and between nations - Returns to financial wealth, profits and interest
are a major factor in the income disparities seen
in the US and elsewhere - What is a capitalist?
- Someone who owns capital.
- Market economies are based on ownership. A
broader distribution of capital ownership could
enhance the efficiencies of the market economy
and possibly increase the ability of the
system to provide important nonmarket goods and
services. How?
12Land ownership
- Land worked by an owner with secure title is more
productive than land worked by sharecroppers or
wage laborers - Why?
- What about day laborers? What incentive do wage
laborers have to do any more than the minimum
required? - Economists typically consider work a disutility
to be endured only to gain access to the material
goods that provide us with utility. Does it have
to be this way? - An economic system should be devoted to the most
efficient means of producing human well-being,
not producing material goods - One policy employee shareholder ownership
programs (ESOPs) - Another what happens if sufficient ownership of
the industry resides with the local population?
What would the local population strive to do?
(Community Shareholder Ownership Programs CSOPs) - What are pros and cons?
13So how to distribute ownership of capital?
- What is the goal?
- Increasing the efficiency of the economy in
satisfying human needs and in internalizing
externalities - What policies will help achieve this goal?
- 1. Recognize that productive assets wear out and
must continually be replaced. Working toward
broader ownership does not require that we
redistribute existing property but change
ownership patterns for new capital - 2. Mechanisms for achieving this have been tested
and supported - ESOPs (Employee Shareholder Ownership Programs)
- Most widely used system for broadening ownership
patterns in capitalist countries. A number of
tax incentives and other subsidies.. - Government contracts.. Preferential treatment
14Distributing the returns to natural capital
- (1) returns from the extraction of natural
resources are often classified as profit when in
reality most are actually rent - What is rent?
- Rent is the profit above and beyond what is
required to supply the resource. The supply of
nonrenewable resources is fixed. The sales price
of many renewable resources if often higher than
would be required to supply the market - (2) many of the returns to natural resources are
in the form of hidden subsidies - How?
- Externalities
15How? Some ideas
- (1) ending public subsidies
- Example pay small royalties for extracting
state-owned resource - (2) Alaska Permanent Fund and Sky Trust
- Sky trust?
- Bundle of policies designed to address scale,
distribution and allocation. Scale and allocation
via quotas that are auctioned off in ITQ. Returns
would go into at trust fund to be equally
distributed to all citizens. Redistribution of
funds how? - What are some concerns with this idea? How could
it be improved? - (3) land tax
- Land ownership typically highly concentrated.
Note land is more valuable due to its proximity
to others. Land values created by society, not by
the landowner. But land supply is fixed. Thus all
returns to land are economic rent
16More on land tax
- One thought since society creates the value in
land, society should share in the returns to land - Options?
- Redistribute land ownership
- Or redistribute the rent via land taxes
- Higher tax increases cost of owning land and thus
decreases value of land - Theoretically the price of land should the net
present value of all future income streams from
that land - Higher tax reduces the income stream and thus
reduces the price land speculation becomes more
expensive - Lower prices make land and home ownership more
accessible
17Chapter 23
18Holistic view
- is it true that if mechanisms can be developed
for internalizing all external costs and valuing
all nonmarket goods and services, market alone
would lead to efficient allocation? - what are the asymmetric information flows that
shape our preferences and influence resource
allocation? - what are the policies aimed at macro-allocation?
(allocation of resources between private and
public goods) - What are some problems confronting the allocation
of resources under local control and national
sovereignty that supply global public goods? - What is a definition of efficiency more
compatible with the goals of ecological
economics?
19Pricing and valuing nonmarket goods and services
- Remember markets lead to efficient allocation of
market goods by using the price mechanism to
balance supply and demand - So economists argue that if we could find
monetary values for nonmarket goods and on
nonmarket ecosystem services we could use the
market mechanism to efficiently allocate
nonmarket goods - So much research in env eco on calculation of
prices of nonmarket goods
20Lets examine this
- What is more expensive water or diamond?
- What is more valuable? How?
- Price is exchange value or the marginal use
value of the good or service in question - Use value is the total value or the value of
all units together - The use value of water is infinite
- But where this resource is abundant, the value of
an additional unit approaches 0 - When it is scare, an additional unit may mean the
difference between life and death, so the
marginal value becomes immeasurably large - Same applies to any essential good or service
21In essence
- When an essential resource is scare, the marginal
value is extremely high, and it increases rapidly
with growing scarcity - As we approach ecological thresholds, the
marginal value and thus the price of ecosystem
goods and services will increase very quickly - How to internalize those ecosystem values? We
need to constantly recalculate them and
re-centralize the information and then re-feed it
into the market mechanism via taxes or subsidies - This process is expensive
22Uncertainty, ignorance and unfamiliarity
- Additional problems
- The methods for valuing nonmarket goods are
filled with problems - Most depend on artificially constructed markets
- Two big problems
- Lack of knowledge of ecosystem function
- Lack of familiarity with valuing nonmarket goods
- Contingent valuation
- Carefully read Box 23-1 and Box 23-2
23Time, distribution, and valuation
- What about the time factor?
- Typical decision sacrifice a renewable flow from
a natural fund-service for a nonrenewable
fund-service or for a one-time liquidation of
stock? - Compare present values with future values
- How?
- No agreed upon objective rule for determining an
appropriate discount rate - Ethical question about intergenerational
distribution
24Market vs nonmarket values
- Market for votes?
- Eco eco Attempting to calculate an exchange
value for all nonmarket goods, then using that
value to decide what we will preserve and what we
will destroy is an example of economic
imperialism - Ecological economics takes the broader
perspective that such methodologies are
inadequate to capture the range of human values
and physical needs we have for nonmarket goods.
We should act on our knowledge that zero is the
incorrect price and spend our time trying to
improve upon and implement policies that
recognize they have significant, often infinite,
value
25Macro-allocation
- What is it? It is the problem of how to allocate
resources between the provision of market and
nonmarket goods - Government plays a role in providing nonmarket
goods and can influence demand through taxes
and subsidies - Do the people have enough information regarding
nonmarket goods and services to influence their
government? - What are the policies addressing information
flows?
26Asymmetric information flows
- What is it? Where either the buyer or seller has
information that the other does not have, and
that information affects the value of the good or
service exchanged - A market failure. Example?
- How does this lack of information affect price?
- Buyer adjusts the price based on the risk the
risk-adjusted price lt value. Rational seller
wont sell at that price. The market thus
provides products at that reduced value - Advertising buy. Advertising for not buying?
- Advertising convinces us to degrade or destroy
public goods for private gain. Explain. - Advertising creates wants by making us believe we
need but it gives us no greater ability to
satisfy those wants - What can be done?
- Tax advertising as an externality? A public bad?
- Full disclosure advertising?
- Free time for public service announcements?
27Additional points
- Spatial aspects of nonmarket goods
- Local level? National / regional level? Global
level? - International policies
- beneficiary pays principle those who benefit
pay for the benefits they receive - International subsidies for ecosystem
preservation - Transaction cost of getting the wealthy nations
to agree to pay Brazil, eg, to reduce
deforestation - How much each must pay
- To whom should the subsidy be paid
- ICMS ecologico a tax on merchandise and
services some money refunded to municipalities
to the extent they meet ecological goals a
payment for provision of ecological services.
Funds dispersed after goals are met - How to do it globally?
28Redefining efficiency
- Comprehensive efficiency ratio of services
gained from manmade capital stock to the services
sacrificed from natural capital stock - Service efficiency
- Technical design efficiency, allocation
efficiency, and distribution efficiency - Maintenance efficiency or durability
- Growth efficiency of natural capital and Harvest
efficiency - Natural capital stock/natural capital stock
services sacrificed - Either increase Natural capital stock or decrease
sacrifice
