السلع المتمايزة: المنافسة عند برتراند

The Bertrand model with differentiated products builds on the classic Bertrand competition framework by accounting for product differences, such as brand identity, quality, designs, and technological innovations. 

In this model, price becomes the primary competitive variable, along with product differentiation, as firms aim to attract consumers while maximizing profits.

The degree of differentiation plays a crucial role in determining market outcomes. When differentiation is high, price competition lessens, enabling firms to charge premium prices and achieve higher profit margins. Conversely, minimal differentiation intensifies competition, driving prices closer to marginal costs.

Consider the automotive market as an example. Tesla and Ford both compete in the electric vehicle segment, but their competition extends beyond just pricing. 

Tesla leverages strong brand identity and technological leadership to sustain premium pricing and high margins, demonstrating the advantages of significant differentiation.

Meanwhile, Ford’s focus on affordability appeals to cost-conscious consumers. It shows how firms with less differentiation can remain competitive by optimizing production efficiency and targeting broader market segments.

These examples illustrate how different strategies can succeed depending on the degree of product differentiation.
