“What is a price? It is a proposed point of agreement between a buyer and seller. The proposal is the key. It is not a marching order. Past prices represent deals done in history. Current prices represent possible deals in the future. Prices embed vast information about perceived realities: resource availability, consumer demand, cultural biases and habits, speculations about the future. The price is also an amazing tool. It provides an objective basis for accounting and the assessment of profit and loss. Without prices, real prices rooted in real market experience, we’d been lost.”
