“Ecological monsters” (Eco-monsters):
European Agreement on Landscape(Law n. 14, 9th January 2006)

Eco-monsters: definition (1)
From the economic point of view, an “eco- monster” can be defined as:
• an investment not carried out until the complete accumulation of capital (uncompleted investment)
• an unproductive intermediate good, which is a mere encumbrance on the landscape perception of a certain resort
![Page 4: Tourism Investments Under Uncertainty: an Economic Analysis of “Eco-monsters”](https://reader033.fdocuments.in/reader033/viewer/2022042719/56813b1d550346895da3d01f/html5/thumbnails/4.jpg)

Eco-monsters: definition (2)
It is therefore an outcome of a wrong decision, which implies:
• A market failure (the firm interrupts and abandons an investment) ending in an uncompleted capital accumulation
• A public failure (the policy maker can not avoid the rising of “eco-monsters”) ending in an environmental damage

Eco-monsters: economic effectsBP(K) private benefice; CA(K) environmental social
cost tax on private benefice
• Environmental-social equilibrium
BP’ (K*) = CA’ (K*) K* > 0
• “Paga chi inquina”: taxes on private benefices
BP > 0 Used for recovering
environment
• If I > 0 but K° is uncompleted
BP(K°) = 0 e BP’ = 0 CA(K°) > 0
• Then BP = 0Who does it pay for
recovering environment?

Eco-monsters: some examples
• A factory initiated but not completed• A building stopped at the carrying structure• A tourism harbor abandoned before
receiving the moorings• An hotel on the beach without rooms• An amusement park without entertainments• A tourism park without accommodation
facilities• A golf course without holes

MotivationThe aim of this work is to find out the conditions for which an “eco-monster” can be built as a bizarre (paradoxical), but legal, consequence of the rational choices of two agents:
• a firm starting the realization of a plan (beginning an investment) by asking to the local policy maker the building permit
• a policy maker with the competent and discretional authority of granting the permit to build

AssumptionsWe use the simplest possible model:
• Two risk-neutral agents (firm, policy maker)• Complete and symmetric information• Limited economic horizons• Null interest rate• Money valuable environmental damages• Final goods and factors of production markets
which are independent and in perfect competition
• Discrete deterministic variables• Binary (dichotomous) random variables

Framework• A stochastic framework, for costs and prices
• A specific/irreversible investment from the firm/environmental point of view
• Environmental damages (externalities)
• The possibility for the firm to take up real options on the possibilities to undertake or to abandon the investment
• One shot game, for the policy maker• Sequential game, for the firm

Economic/environmental investment
In this work the following terms are used:
• “reversible/irreversible” with reference to the environmental investment properties, which can cancel/not cancel the environmental damage effects
• “specific/unspecific” with reference to the private firm investment properties of economic recoverability/unrecoverability (sunk costs)

Environmental dammages
• If the capital is completed, it can produce/non produce negative environmental externalities C 0 (only if C = 0 there are not externalities)
• If the capital is not completed and the investment is specific and irreversible, there will be an “eco-monster” with an environmental monetary damage c 0 (only if c = 0 the investment is reversible)
![Page 14: Tourism Investments Under Uncertainty: an Economic Analysis of “Eco-monsters”](https://reader033.fdocuments.in/reader033/viewer/2022042719/56813b1d550346895da3d01f/html5/thumbnails/14.jpg)

“Eco-monsters”
If the capital is not completed and the investment is specificand irreversible, there will be
an “eco-monster” with damage:c 0
(only if c = 0 the investment is reversible)
If the capital is completed, it can produce/non produce
negative environmental externalities C 0
(only if C = 0 there are not externalities)

Financial options: reference
• Call option is a financial contract between two parties, the buyer and the seller of this type of option. The buyer of the option has the right, but not the obligation to buy an agreed quantity of a particular good or financial instrument (the underlying instrument) from the seller of the option at a certain time (the expiration date) for a certain price (the strike price). The seller is obligated to sell the good or financial instrument should the buyer so decide. The buyer pays a fee for this right.
• Put option is a financial contract between two parties, the buyer and the seller of the option. The put option allows the seller the right but not the obligation to sell a good or financial instrument to the buyer of the option at a certain time for a certain price. The buyer has the obligation to purchase the underlying asset at that strike price, if the seller exercises the option.

Real OptionsA Real Option is the right, but not the obligation, of a firm to undertake some capital investment decision (to begin or to abandon it):
• Call option, right to undertake an investment subject to a permit to be asked to the policy maker, for which it is necessary to pay ex-ante an exogenous lump sum tax
• Put option, right to interrupt an investment during its lifetime and to sell the cash flows over the remainder of the investment for some salvage value
• Our assumptions: it lasts 3 periods, it is renewable and not tradable (in contrast to financial option)
![Page 17: Tourism Investments Under Uncertainty: an Economic Analysis of “Eco-monsters”](https://reader033.fdocuments.in/reader033/viewer/2022042719/56813b1d550346895da3d01f/html5/thumbnails/17.jpg)

One shot game : the variables (1)
• S > 0 –> costs on T = 1 (exogenous lump sum tax, or guarantee deposit, to be paid ex-ante if the building permit is granted)
• D > 0 –> costs on T = 2 (firm loss for the possible investment interruption)
• D’ –> investment salvage value on T = 2 if the investment is unspecific then D’ > 0 if the investment is specific then D’ = 0
• K > 0 –> costs on T = 3 (cost of the completed capital)
![Page 18: Tourism Investments Under Uncertainty: an Economic Analysis of “Eco-monsters”](https://reader033.fdocuments.in/reader033/viewer/2022042719/56813b1d550346895da3d01f/html5/thumbnails/18.jpg)
18
Timing (2)• The firm can ask a permit only every 3 periods
interval (T = 0,3,6,…)• The investment is completed in 2 periods (on T = 3)• News (uncertainty) on price existing only on
completed capital price (on T = 2)

The Governmentobjective function
where α and β are weights measuring the social preferences (policy maker’s ideology) for the “budget variables” (taxes S and τ) and for the “environmental variables” (externalities c and C)
This function can also be interpreted as the approximation of a separable and addictive social welfare function
and can be interpreted in terms of a social net monetary benefit.

The Governmentobjective function (segue)
In order to simplify the computation we divide each term by β and we obtain:
where γ = α / β measures the “partisan party effect” on the game equilibrium:
• if α > β, then γ > 1 and the policy maker attaches more importance to the “budget variables”
• if α < β, then γ < 1 and the policy maker attaches more importance to the “environmental variables”

• The rational conditions of a legal “eco-monsters” are also subject to an existence condition: S and τ must be upper and lower bounded in the following ways
0 < Smin(in order that we 0) < S < Smax(in order that Ye 0)
0 < min(in order that we 0) < < max(in order that Ye 0)

Results (1)
The equilibrium condition implies the conditions for the rising of a rational and legal “eco-monster”:
• sufficient conditions –> the capital is not completed and the investment is irreversible (c > 0) and specific (D' = 0)
• necessary conditions –> the completed capital price is lower bounded such that * ≥ max[H
firm;Hpm]
• existence conditions –> the proportional building tax τ*(S) and the lump-sum tax S*(τ) must be upper and lower bounded such that Ye ≥ 0 and we ≥ 0

28
Results (2)It will not be built any “eco-monster” in the following cases:
• a deterministic framework (independently from the completed capital externalities C 0)
• a stochastic framework limited to the first period, i.e. if there will not be any uncertainty in the second period, such that the firm has not any incentive to exercise the put option (abandon the investment)
• the investment is unspecific or reversible (independently from the completed capital externalities C 0)

Conclusions (1)Policy implications:in case of effective economic policy, the
model allows to choose the building taxes (S and τ) like instrumental variables, in order to monitor the “eco-monsters” frequency
in case of ineffective economic policy, an efficient solution for the policy maker could be the introduction of Pigou taxes, i.e. taxes lying on the environmental externalities (c or C)
![Page 34: Tourism Investments Under Uncertainty: an Economic Analysis of “Eco-monsters”](https://reader033.fdocuments.in/reader033/viewer/2022042719/56813b1d550346895da3d01f/html5/thumbnails/34.jpg)
34
Conclusions (2)• the taxes allow a differentiated policy in order to
incentive only some tourism investments: in some cases (i.e. when (firm > pm) the policy maker can fix a low value of the building taxes S and τ for unspecific and reversible investments, while it can fix a high value of S and τ for specific and irreversible investments
• the model allows to evaluate the effects of the policy maker’s ideology γ on the “eco-monsters” frequency: since γ does not affect the firm’s implicit price firm, when firm < pm then an increase in the importance attached by the policy maker to the “budget variables” causes an increase of the “eco-monsters” frequency
