The Tragedy of the
Commons

The Tragedy of the Commons

The Tragedy of the Commons
« Each man is locked into a system
that compels him to increase his
herd without limit -in a world that
is limited. Ruin is the destination
toward which all men rush, each
pursuing his own best interest in a
society that believes in the freedom
of the commons. Freedom in a
commons brings ruin to all»
(Hardin1968)
(Battersby 2017)

Assumptions (Stillman 1975)

The Tragedy of the Commons
Grazing lands, Chopta, IndiaDegraded forest, Congo Overfishing, IndiaWater shortages, Bolivia

Modeling fisheries
The Gordon-Schaefer model

Overfishing and poverty
« It is hard to make a living as a fishermen
these days. There is no fish left. I only go if
there are no other possibilities to make
money»
« I used to catch very large fish. Now the
only thing I can possibly get is baby octopus.
I know it is bad. I know it is wrong. But I
have no choice»
(Zanzibar)

The World Commission on Environment
and Development (WCED)
«Humanity has the ability to make development
sustainable to ensure it meets the needs of the present
without compromising the ability of future generations
to meet their own needs»
«…our future is severely threatened, however, if we do
not focus on how to protect our common heritage »

Hardin’s solution
Cedeourfreedomstothestate,tobeboundby“mutualcoercionmutually
agreedupon”
Withouteffectiveinstitutionstolimitwhocanusediverseharvestingpractices,
highlyvalued,common-poolresourcesareoverharvestedanddestroyed(FAO
2005;Mullonetal.2005;MyersandWorm2003).
Lackinganyhigherauthoritytoreinintheselfishnessofnations,arewe
doomed?(Battersby2017)

Governing the Commons
Commonpoolresourcescanbegovernedinvariousways.
Threemaincategories:
▪PrivateProperty(Demsetz,1967;Raymond,2003),
▪GovernmentOwnership(Lovejoy,2006;Terborgh,1999,2000)
▪CommunityControl(VermillionandSagardoy,1999)

Private property
•Privateforests
•Righttousewater,harvestfish,etc.
•Typicallytradable
•Sometimeseventransferableintime(harvestmoretodayandless
tomorrow...)
•Canbeveryefficient
•Maindisadvantage:Howtodealwithinequality?

•Oftendifficultfinancialandlegalbasis

Community property

▪Oftensuccessful,butnotalways!(Acheson2003;Andersson2004;BrayeKlepeis2005;Gibsonetal.

▪Reliesontheexistenceofsocialcapitalandsharedunderstandingofownership,stewardship,

▪Maindisadvantages:
•Littlecommunityinvolvement
•Mayleadtounequaloutcomesinfavorofrulingelite
•Limitedscopeto“fix”fromtheoutsideifthingsgowrong

Experiments, Cooperation & Commons
▪What makes a self-governing group effective?
▪Growing interest to understand behavior in the field
➢Cooperation as a left-hand side variable to understand which external
factors undermine or foster cooperation (as identified in Ostrom2009)
➢Cooperation as an explanatory (i.e. right hand side variable) to
understand decisions regarding investment, resource exploitation etc.

Governing
the
Commons

« There are no ‘one-size-fits-all’
solutions that can be applied to
all fisheries, all forests, or all
water systems »
(Grafton, 2000; Ostrom, 2007)

Natural Resource Curse

How does a state's natural
resource wealth influence its
economic development?

Background
➢Expectation:Increasedendowmentsshouldpromoteeconomicdevelopment
andtranslateintomoreproduction.
➢Viewin1950s(Vines,Lewis,Sprengler):Developingcountriessufferfrom
imbalancebetweenlaborandcapital.
➢Resourceabundance:exportprimarycommoditiesorattractforeign
investment,collectrents+providepublicgoods.

Some quotes…
«The possession of a sizable and diversified natural resource base is a major advantage to any country
embarking on a period of rapid economic growth »(Ginsburg, 1950)
«… natural resource endowments would enable developing countries to make the transition from
underdevelopment to industrial ‘take of ’…»(Rostow, 1961)
«Natural resources could facilitate a country’s economic development by providing domestic
markets and investible funds »(Krueger, 1980)
Mainstream view: natural resources are a blessing!

Oooops….
▪Sachs&Warner(1995,1997,2001):Resourceabundantcountriesgrowslowerthan
resourcepoorones(casualinspectionandregressionanalysis)->resourcecurserather
thanablessing!
▪Ifresourceendowmentrisesbyonestandarddeviation->onepercentfallineconomic

▪Immenselypopularresearchtopic.Extremelyinfluential:pickedupbyWorldBank,IMF,
manyNGOs(e.g.SavetheChildren,Oxfam).Goodstory.
« …the conventional wisdom now is arguably the exact opposite of what it
was prior to the late 1980s »(Rosser, 2006)

Institutions matter

▪Auty(2001);Ishametal.(2005);Leite&Weidmann(1999)andNorman(2006)generallyagreethatthe

▪Mehlumetal.(2006)showthatincountrieswithgoodinstitutions,resourceabundanceattracts
entrepreneursintoproduction.Incountrieswithweakinstitutions,however,entrepreneursarediverted

The effect of resource abundance on institutional quality is a challenging area of future research.

How can the resource curse be overcome?

2.Politicalandsocialchanges
3.Bypassthestate

5.Interventionbyinternationalorganizations

Are natural resources bad for
development?

▪Davis(1995)andPapyrakisandGerlagh(2004),usingmineralproductionoverGDP,deliversless
clear-cutresults.

What type of natural
resources?
Fearon (2005),Fearon and Laitin(2003),Ross
(2003a),Sala-i-Martin and Subramanian (2003),
Ishamet al. (2002),De Soysa(2000) andLeiteand
Weidmann(1999) have pointed to ‘point source’
natural resources –for instance, oil, minerals, and
plantation crops –as being particularly problematic.
Ross (2003b) presents evidence to suggest that it is
‘lootable’ resources such as diamonds (particularly
alluvial diamonds) and drugs (particularly opium and
coca) rather than point source resources that are the
most likely to produce civil war.

Is this the only
truth?
Several countries that are
doing well today became
prosperous because of, rather
than in spite of, their natural
resources: Australia, Canada,
the US, New Zealand, Iceland
and the Scandinavian
countries, the diamond-rich
Botswana, Chile, Brazil, Peru,
Malaysia and Thailand.

Is this the only truth?
▪Davis(1995)hasshownthat,bycertaineconomicandsocialmeasures,mineraleconomies
outperformednon-mineraleconomiesbetween1970and1991.Thesemeasuresinclude
averageGNPpercapitaandimprovementinvarioussocialindicatorssuchasinfantmortality,

morelikelytoendquickly.
▪Ballantine(2003)hassuggestedthatnaturalresourceabundancehas,insomecases,

Correlation or Causality?
«Those arguing in favourof the notion of a resource curse have merely inferred
causality from the evidence of correlation. However, the direction of causation
may in fact run the other way.» (Rosser2006)
«…natural resource dependence may be a symptom of underdevelopment
rather than the cause » (Schrank2004)

Take Home Messages
▪The tragedy of the commons and the curse of natural resource abundance
has been a popular topic.
▪Institutions matter!
▪Majority of empirical work has used a measure of resource dependence as
a proxy for resource abundance.
▪The evidence is by no means conclusive.
▪There are exceptions.
▪No Cure-Alls
