2.3.2 The strong Porter Hypothesis
Brännlund and Lundgren (2009, p. 9) defined the strong PH
as the productivity gains induced by the ER so that the whole costs of
attaining it are, at least, compensated by the productivity increases. In this
context, it is relevant to point out that Porter (Porter, 1991; Porter and van
der Linde, 1995) has the credit of giving an approach that deviates from the
dominant design in those days. Porter's argument was that: appropriate
government environmental intervention can trigger innovations that can offset
the costs of compliance with the regulations. As a result of strict ER,
companies will reconsider their production process and will develop new
approaches to reduce the pollution while lowering their costs and / or
increasing their production. The possibility that regulation encourages
innovation imply that firms decisions are not always the optimal choices as
there is a high level of information imperfection and a certain inertia while
organisational opportunities and technologies are developed continuously. Thus
many innovation opportunities are overlooked by firms as their level of
awareness is limited. If ER stimulus to eco-innovation is sufficiently
important then ER would offer the possibility to improve environmental
conditions at zero cost or negative net costs by improving productivity.
Consequently, by stimulating innovation, ER may actually make businesses more
competitive. As an example, regulations on recycling products could lead to the
recovery of valuable materials more easily. Both consumers and producer could
then end up winners when disposing of the consumed product. (Lanoie &
TANGUAY, 1999)
Undoubtedly, such a view has received close attention from all
stakeholders who want stronger environmental policies, such as
environmentalists. If ER may be without costs or even with negative costs then
regulation is good for both the environment and the businesses.
Porter initially expressed his argument in a one-page article
(Porter 1991) and then extensively formulated it in a common article with van
der Linde (1995) and later on with Esty (1998). According to Porter (1991)
«strict environmental regulations do not inevitably
hinder competitive advantage against foreign rivals (p.
96)». And «... the environment-competitiveness debate has been framed
incorrectly (Porter & van der Linde 1995, p. 97)». The authors
emphasised the crucial role of innovations as their core argument. Wagner
(2004) indicated that: «In reality, one is faced with a dynamic
competition process, rather than a framework of static optimization.»
Because firms are «... currently in a transitional phase of industrial
history where companies are still inexperienced in dealing creatively with
environmental issues (Porter & van der Linde 1995, p. 99)», which
implies incomplete information and organisational inertia. Wagner (2004) adds:
«In such a situation properly designed regulation can have an influence on
the direction of innovation in that (Porter & van der Linde 1995, p.
99-100):
- It signals to firms resource inefficiencies and possibilities
for technological improvement;
- If focused on information provision, it can increase firms'
awareness for improvement potentials;
- It reduces the uncertainty of net paybacks from investments;
- It «... motivates innovation and progress» (Porter
& van der Linde 1995, p. 100);
- It provides a `level playing field' and is necessary in
situations with incomplete offsets.»
The idea underlying the reasoning of Porter is that pollution is
generally associated with resources and raw materials that are not fully
utilised or wasted energy.
«Pollution is the emission or discharge of a (harmful)
substance or energy form into the environment. Fundamentally, it is a
manifestation of economic waste and involves unnecessary, inefficient or
incomplete utilization of resources, or resources not used to generate their
highest value. In many cases, emissions are a sign of inefficiency and force a
firm to perform nonvalue-creating activities ... Innovation offsets will be
common because reducing pollution is often coincident with improving the
productivity with which resources are used.» (Porter and van der Linde,
1995, p. 98)
Thus there is room for innovation in order to prevent
pollution and reduce the waste. Specifically, Porter refers to two broad
categories of innovations. Firstly, process improvements when reducing
pollution is associated with higher productivity through material savings,
reduced energy needs and reduce costs of disposal; a typical example is to find
ways to use waste, scrap and residues as new combustion source. Secondly, there
are also gains to be made at products level where reducing pollution is
accompanied by a design
product of higher quality, safer, cheaper, with more value for
the consumer or is less costly to the trash. (Lanoie & TANGUAY, 1999)
The academic research conducted by Sinclair-Desgagné
and Gabel (Sinclair-Desgagné 1999; Gabel & Sinclair-Desgagné
2001; 1993) came to a similar conclusion, they considered in fact ER as
«... an industrial policy instrument aimed at increasing the
competitiveness of firms, the underlying rationale for this statement being
that well- designed environmental regulation could force firms to seek
innovations that would turn out to be both privately and socially profitable
(Sinclair-Desgagné 1999, p. 2)». Moreover they proposed a number of
conclusions such as «... [it is] inconsistent, albeit convenient, to
assume that markets are flawed but that firms are perfect (Gabel &
Sinclair-Desgangé 2001, p. 149)». Another conclusion was that
although «standard neoclassical-economics models do not support the
systematic presence of low-hanging fruits (Sinclair-Desgagné 1999, p.
3)» the authors indicated that «[I]nnovation itself is not free, and
if one prices managerial time and all other in puts correctly at their
opportunity costs, it should become clear that putting stronger environmental
requirements on polluting firms generally increases their production cost more
than their revenue (Sinclair-Desgagné 1999, p. 2)». Ambec and Barla
(2006) observed that the management tend to be `present-biased' and may delay
investment in costly assets even if they may be productive («low-hanging
fruits»):
«Because the cost of innovating is for «now»
while the benefit is «later,» a present-biased manager will tend to
postpone any investments in innovation. By making those investments more
profitable or requiring them, environmental regulations help the manager
overcome this self-control problem, which enhances firm profits» (Ambec,
et al., 2010).
In addition, according Gabel & Sinclair-Desgangé
(2001) «[It] is logically most likely in situations where the firm is far
from the efficiency frontier, where the burden of the compliance cost is light,
and where the shift to the frontier can be made cheaply» (p. 152).
Finally, Xepapadeas & de Zeeuw (1999) concluded that «basic argument
nevertheless remains the X-efficiency argument that external shocks caused by
stringent environmental regulations may reduce inefficiencies and failure
within the firm».
Another way to look at the situation is to suppose that
businesses might operate under their potential because of bad management and
lack of perfect information. A clear definition of property rights (Coase,
1960) with regulation to limit information asymmetries (Akerlof, 1970), may
lead to Porter's the win-win or positive sum game with Pareto
improvement. In practice, however, regulation usually has been
associated with decreased competitiveness, deterring innovative activities
(Cerin, 2006).
Ambec and Barla (2007) explain, through a game theory
application, the spill-over effect of R&D investment that justifies the
Porter hypothesis. Consider two firms with the same technology and each with a
monopoly on two separate markets. They get a profit of ðp. Each
firm must decide whether to invest in research and development (R&D) to
achieve a more productive and cleaner technology that allows it to achieve a
gross profit of ðV with ðV >ðp. The cost
of developing this new technology is I. Consider the extreme case where the
spill-over is complete so that a company has a perfect access to results of
another firm at no cost. In other words, innovation is a public good. A company
can have access to new technology at no cost if its competitor invests in the
project. If the two companies perform R & D investment that each should
I/2. The game is represented by the following matrix:
Spill-over effect of innovation
Firm 2 No R&D R&D
Firm 1 NoR&D
R&D
ðp, ðp
|
ðv, ðv -I
|
ðv -I , ðv
|
ðv -I/2, ðv -I/2
|
Figure1: Ambec and Barla (2007)
So if ðv-I <ðp but
ðv-I/ 2> ðp, then this is exactly the
situation of the so-called classic `prisoner's dilemma': the Nash equilibrium
is `no firm invests' while if they could cooperate, both would benefit from the
jointly developed the new green technology. Environmental regulation as a
standard that forces the adoption of new technology could therefore benefit
both players. Other environmental regulations a priori costly for the company
such that a carbon tax or a system of emission permits would lead to the Nash
equilibrium where both firms invest in R&D. They save on the costs of
R&D spill-over, the new technology requires an investment of individual
I/2. Their final gain is ðv-I/2, greater than the gain before
regulatory Nash equilibrium ðp. (Ambec & Barla, 2007)
