Given FY2023 iPhone revenue trends, which specific metric best captures the percentage of the 1.5 billion active users purchasing a new device in a given period?
Apple Watch generated over $40 billion by 2023. Which metric measures the ratio of these secondary ecosystem devices sold relative to primary iPhone units?
Proponents of the iPhone Duo cite Samsung's 30% foldable growth. Skeptics argue this growth does not translate to Apple due to what specific characteristic of Apple's ecosystem?
4.Bloc 2 - Academic TheoryMoyen· Bass Diffusion Model (Bass 1969)
Under the Bass Diffusion Model (Bass 1969), the probability of adoption at time t depends linearly on which specific factor within a constant and finite market?
5.Bloc 2 - Academic TheoryMoyen· Optimal Replacement Model (Rust 1987)
According to the Optimal Replacement Model (Rust 1987), the assumption that consumers maximize expected discounted utility breaks down when which specific distortion affects replacement costs?
6.Bloc 2 - Academic TheoryMoyen· Product Line Cannibalization (Moorthy 1984)
In Product Line Cannibalization (Moorthy 1984), a firm introducing a higher-quality variant must price it to satisfy which specific mathematical constraint across distinct consumer segments?
How do global inflationary pressures and economic slowdowns mathematically alter the replacement cost threshold in the Optimal Replacement Model, thereby extending current smartphone upgrade cycles?
As the smartphone market matures, how does a cohesive hardware-software-services ecosystem impact the switching costs variable in the Network Externalities and Lock-In model?
9.Bloc 4 - Expert SynthesisExpert· Bass Diffusion Model (Bass 1969) vs Optimal Replacement Model (Rust 1987)
Regarding consumer purchase frequency, how does the single-purchase assumption in the Bass Diffusion Model (Bass 1969) fundamentally conflict with the core mechanics of the Optimal Replacement Model (Rust 1987)?
10.Bloc 4 - Expert SynthesisExpert· Network Externalities and Lock-In (Katz & Shapiro 1985) vs Product Line Cannibalization (Moorthy 1984)
While Network Externalities and Lock-In (Katz & Shapiro 1985) assumes homogeneous network benefits, how does Product Line Cannibalization (Moorthy 1984) treat consumer utility when pricing new variants?
