2Questions
- What are the primary recreational/ amenity
benefits associated with Caspian Sea resources? - What are the main analytical techniques used to
estimate these values? Differences between
revealed preference and stated preference
techniques. - What are the main economic policies that can be
used to regulate or manage these uses?
3Selecting the appropriate valuation technique
(again)
4Principal Recreational/ Amenity Benefits
- Direct, consumptive uses fishing, hunting,
gathering of marine organisms, oil and gas? - Direct, non-consumptive uses swimming, sailing,
viewing wildlife, transportation, others? - Indirect uses ecosystem services, vistas and
views, amenity benefits
5Matching Economic Valuation Technique to Uses and
Users
- Direct, consumptive uses changes in production,
CVM, Travel Cost - Direct non-consumptive uses CVM, travel cost,
RUM (random utility models), hedonics, others - Indirect uses changes in production of ecosystem
services, replacement cost/ preventive
expenditures, hedonics, others
6Valuing Recreational Uses
- Usually done by one of three means
- Observing net admission fees/ permit fees paid (a
minimum estimate of WTP) - Use of Travel Cost approach that relies on
revealed preference information on travelers
time and costs of visiting a location - Use of CVM that relies on stated preferences to
determine WTP (willingness to pay) for use of a
location
7Revealed vs Stated preferences
- Economists tend to prefer revealed preference
approaches since they rely on real data on
expenditures and markets - Can be collected from the market or via use of
surveys - Real dollars exchanged for various goods and
services - Stated preferences (e.g. CVM), however, are
sometimes the only valuation approach possible.
When is this true???
8A Simple Travel Cost Example (revealed
preference) value of Lake Sevan in Armenia
- Visitors to Lake Sevan in Armenia are surveyed to
find their cost of travel and frequency of
visits. - This information is used to estimate a demand
curve for Lake Sevan recreation - Different demand curves are estimated for
Armenians and foreign visitors (due to great
differences in income levels) - Travel Cost does NOT capture non-use values by
both Armenians and foreigners
9The value of Lake Sevan can also be estimated by
use of the CVM approach (stated preferences)
- CVM can be used when a market is only partially
developed (and sales data hard to obtain).
Especially useful for non-use values. - In theory CVM can capture the MAXIMUM willingness
to pay for the use of a resource - Advantage of CVM you will always get an answer
- Disadvantage of CVM you will always get an
answer!!!
10Valuing Ecosystem Services Cost-side Valuation
Techniques
- Include the Replacement Cost approach and the
Preventive Expenditures approach (both approaches
are closely linked) - Uses information on replacing a lost service or
function, or preventing the damage from occurring - For example, the cost of replacing flood
protection benefits of a wetland, or - The cost of replacing natural water filtration/
treatment benefits by mechanical/engineering
approaches
11Replacement-cost approach New York City (NYC)
watershed
- The question was whether it was better to protect
NYCs watershed and keep water clean, or allow
the watershed to be developed and clean and treat
the water when it reached NYC - The economic analysis showed that it was CHEAPER
(less costly) to protect the watershed by an
investment of 1 billion plus in purchasing land
in the watershed, than to build and operate a
water-treatment plant closer to NYC
12Valuing Amenity Benefits Hedonics (revealed
preferences) and CVM (stated preferences)
- Amenity benefits are usually valued by either
Hedonic approaches or via CVM (surveys) - Hedonic effects are commonly seen in pricing of
hotel rooms, real estate, other tangible goods or
services that have an amenity value component - Hedonic approaches use information on actual
market transactions to estimate the WTP for these
amenity values
13Hedonic Valuation Approaches
- Use information on observed behavior to estimate
WTP (willingness to pay) for an environmental
amenity (an economic good) or disamenity (an
economic bad) - Requires information on transactions and
differences in environmental quality - Often applied to housing, hotel rooms or other
locational decisions (e.g. wages and a sunshine
tax)
14Example 1 Houses near the Zandvlei Wetland in
Capetown, South Africa
15Capetown Case (contd)
- Basic idea Houses near the Zandvlei wetland sell
for more, an environmental premium. How large
is this premium? - The analysis was based on sales data on housing
over the past 4 years the results were then
extrapolated to the entire housing stock in the
area - Premium per house for water frontage was about
R130,000 per house (about US13,000) (see van
Zyl/ Leiman paper Tables 2 and 3) - The results were very similar to estimates made
by estate agents (expert opinion approach) for
the same area Hedonic approach value of R77
million vs Expert opinion value of R88 million
16Discussion of Capetown Results
- The waterfront (open space) premium was less than
10 (and in some cases was even negative due to
security concerns) - The results are very site specific (and
management specific) and only capture one
aspect of open space values (as embodied in
property ownership) - Hedonic pricing may NOT value certain types of
native vegetation (e.g. fynbos are seen as
unkempt and a fire hazard even though they are a
unique ecosystem) - The hedonic study ignores wider values of open
spaces to recreational users and other parts of
Capetown (as reflected in generally high property
values in all of Capetown compared to other parts
of South Africa the San Francisco effect)
17Hedonic pricing (contd)
- 2. Hotel room pricing in resorts is a market that
clears every day. For example, in hotels on the
beach in Hawaii - Room price varies with floor (higher floors are
more expensive) - Room price varies with view
- ocean view
- garden view usually the parking lot, maybe the
mountains! - Room price varies with season
- High season/Low season
- Or, as in Costa Rica, high season and the green
season (e.g. rain!)
18Hedonic pricing (contd)
- 3.Pricing of faculty flats at a university in
China - In this case a 6 storey building, no lift, one
flat per floor, and the roof leaks. - What is the monthly rental per flat? If ground
floor rents for 100 units per month, what are the
monthly rents for the following floors? - Floor 2 ___
- Floor 3 ___
- Floor 4 ___
- Floor 5 ___
- Floor 6 (top) ___
19Pricing of Professors Flats in Beijing (contd)
- Suppose that the roof is fixed and does not leak,
and that an elevator/ lift is installed. How does
this change the pricing structure? What is the
monthly rental per flat? If ground floor rents
for 100 units per month, what are the monthly
rents for the following floors? - Floor 2 ___
- Floor 3 ___
- Floor 4 ___
- Floor 5 ___
- Floor 6 (top) ___
20Pricing of Professors Flats in Beijing (contd)
- How could this hedonic pricing information be
used to make better decisions?? - To decide whether or not the repairs and changes
are justified? How? - To decide whether or not to build new buildings?
How? - To design a more efficient pricing structure?
How?
