Fighting Bundles: The Effects of Competition on Second-Degree Price Discrimination

Second degree price discrimination

Second-degree Price Discrimination with a Continuum of Types

Assumptions • There is a continuum of types; specifically, a consumer’s type, θ, is an element of the real interval [θ0, θ1]. • Marginal cost is a constant, c. • Because marginal cost is a constant, there is no loss of generality in considering a single consumer whose type is drawn from the distribution F (·) : [θ0, θ1]. • Assume F (·) is differentiable. Let f(·) be the derivative (the density ...

Multi-dimensional Virtual Values and Second-degree Price Discrimination

We consider a multi-dimensional screening problem of selling a product with multiple quality levels and design virtual value functions to derive conditions that imply optimality of only selling highest quality. A challenge of designing virtual values for multi-dimensional agents is that a mechanism that pointwise optimizes virtual values resulting from a general application of integration by pa...

Third-degree Price Discrimination

IN THE LITERATURE OF monopolistic third-degree price discrimination, it has been widely held that a change in aggregate Marshallian social welfare by price discrimination is negative if total output decreases. Among others, Schwartz [1990] verifies this conjecture for any total cost function that depends only on total output, not on its distribution among markets. Letting ∆X and ∆W denote a cha...

the effects of error correction methods on pronunciation accuracy

هدف از انجام این تحقیق مشخص کردن موثرترین متد اصلاح خطا بر روی دقت آهنگ و تاکید تلفظ کلمه در زبان انگلیسی بود. این تحقیق با پیاده کردن چهار متد ارائه اصلاح خطا در چهار گروه، سه گروه آزمایشی و یک گروه تحت کنترل، انجام شد که گروه های فوق الذکر شامل دانشجویان سطح بالای متوسط کتاب اول passages بودند. گروه اول شامل 15، دوم 14، سوم 15 و آخرین 16 دانشجو بودند. دوره مربوطه به مدت 10 هفته ادامه یافت و د...
