industrys profit margin. Therefore, the key concept which allows incumbents firms to
block entries on the already profitable industry is the entry barriers. Entry barriers exist if
it is difficult or not feasible economically for outsiders to replicate the incumbents position
and rest on irreversible resource commitments, such as economies of scale, capital
requirements, brand identity, low-cost production design and so on.
The discount retailing industry was not concentrated in the 1950s, existing a vast range of
competitors, thats why the economies of scale and capital requirements (needed to get
good deals on purchases so as to get attractive prices and investments to build stores) were
not enough how to restrain an in-flux of firms.
The access to distribution was at this time very rudimentary following the classic approach
of manufacturer-wholesaler-retailer, and there were not any firm leading this field. Also
then any firms had developed yet a low cost distribution design as currents high developed
logistics systems which restrain firms to enter on this industry.
By this time there not existed highly developed operational system as to recent time, such
as satellite system communication, electronic data interchange (EDI), high develop
logistics systems, and so on…
Also by this time the learning curve within industry was not enough developed as to
deliver an advantage to any specific firm and to prevent new firms to entry.
Others entry barriers were not a really problem. For instance, related to the vast range of
competitors, there were not well-established and clearly differentiated brand names with
enough loyalty as to prevent the entry of new firms on the industry, the access to necessary
inputs was easy, and the government policy had bolstered consumer self-confidence.
FORCE 2: THE THREAT OF SUBTITUTES
The existence of close substitute products increases the propensity of customers to switch
to alternatives products, which raise the competition level among firms, consequently
lowering the attractiveness and profitability within industry. Clarify that a substitute
product is this that can perform similar functions for customers in order to satisfy the same
needs than the others, not just a physically similar product. Threats worth to mention are,
first those products or services which improve relative price-performances priors products,
switching cost incurred by a firm when the customer switches to a different sort of product
or services, and the buyers propensity to substitutes.
