Why is Platform Pricing Generally Highly Skewed?
نویسنده
چکیده
Bolt and Tieman (2008) suggested that profit function non-concavities may account for the prevalence of skewed pricing by two-sided platform businesses. In the Rochet-Tirole (2003) model, however non-concavity is not necessary for highly skewed pricing. Ubiquitous high pass-through rates are sufficient but implausible. In the Armstrong (2006) model, non-concavity is neither necessary nor sufficient for skewed pricing. In both models, non-concavity is associated with strong indirect network effects; in the Armstrong (2006) model such effects are also associated with dynamic instability. It seems most plausible that the prevalence of skewed platform pricing reflects the prevalence of substantial differences between side-specific demand functions.

Investigation of linear and non-linear estimation methods in highly-skewed gold distribution
The purpose of this work is to compare the linear and non-linear kriging methods in the mineral resource estimation of the Qolqoleh gold deposit in Saqqez, NW Iran. Considering the fact that the gold distribution is positively skewed and has a significant difference with a normal curve, a geostatistical estimation is complicated in these cases. Linear kriging, as a resource estimation method, c...
متن کاملThe Role of Surge Pricing on a Service Platform with Self-Scheduling Capacity
Recent platforms, like Uber and Lyft, offer service to consumers via “self-scheduling” providers who decide for themselves how often to work. These platforms may charge consumers prices and pay providers wages that both adjust based on prevailing demand conditions. For example, Uber uses a “surge pricing” policy, which pays providers a fixed commission of its dynamic price. We find that the opt...
متن کاملX Chromosome Inactivation in Opioid Addicted Women
Introduction: X chromosome inactivation (XCI) is a process during which one of the two X chromosomes in female human is silenced leading to equal gene expression with males who have only one X chromosome. Here we have investigated XCI ratio in females with opioid addiction to see whether XCI skewness in women could be a risk factor for opioid addiction. Methods: 30 adult females meeting DS...
متن کاملWhy Doesn't EM Find Good HMM POS-Taggers?
This paper investigates why the HMMs estimated by Expectation-Maximization (EM) produce such poor results as Part-of-Speech (POS) taggers. We find that the HMMs estimated by EM generally assign a roughly equal number of word tokens to each hidden state, while the empirical distribution of tokens to POS tags is highly skewed. This motivates a Bayesian approach using a sparse prior to bias the es...
متن کاملAsset Pricing with Left-Skewed Long-Run Risk in Durable Consumption
I document that durable consumption growth is highly persistent and predicted by the price-dividend ratio. This provides strong and direct evidence for the existence of a highly persistent expected component. I also document robust evidence that durable consumption growth is left skewed and exhibits time-varying volatility. These properties motivate a model for durable consumption growth as dri...
