La función de penetración de mercado En 1846, PierreFrankcoisVerhulst propuso una formulación matemática plausible del crecimiento demográfico conocida ahora como laecuación deVerhulst. Esta ecuación es unpunto departidaexcelentepara entender el problema de la substitución tecnológica, es decir, la cuestión de cómo una tecnología más avanzada substituirá a una tecnología más vieja.
Como un ejercicio de propositico, Marchetti usa las líneas de tendencia de la Figura 1.8, obtenida sólo de los datos de 1935, y calcula el comportamiento de la cuota del mercado del petróleo empleando la formula:
Los resultados se muestran en la Figura 1.9. Son muy exactos y llevó a Marchettia comentar: “podríamos predecir lacuota demercado fraccionaria delpetróleo en los E.E.U.U. hasta 1970 con una precisión deuno por ciento.”
Si extendemos el gráfico de Marchetti a 2008, encontramos un buen acuerdo del comportamiento del carbón y del gas, en las cuales se basa el pronóstico, pero el modelo no es muy bueno para los tiempos modernos (véase Figura 1.10)
Si durante el período de la penetración del mercado, existe un aumento substancial en capital disponible, éstealterará elíndice de penetración, aunque puede no aumentarlo beneficioso de laempresa. Sería de gran valor si fuera posibleestimar cuántose aceleraría la penetración en función de una cantidad de inversión dada en el nuevo mercado. Desafortunadamente, esto no es todavía posible. La formulación antedicha implicaque cuando unatecnología comienza a penetrar el mercado, el mercado debe ya estarbien desarrolladoy su grado de madurez determinará el índice de penetración eventualmente. Así, “la magnitud de la inversión externa originaldetermina realmente lascondiciones iniciales para el modelo” (Peterka, 1977).Las reglas de la penetración de mercado discutidas en esta subsección proporcionan una herramientade gran alcancepara el planeamiento, pero se deben utilizar con mucha precaución y con mucha atención a las suposiciones implícitas.
