This paper analyzes the e¤ects of net neutrality regulation on investment incentives for Internet service providers (ISPs) and content providers (CPs), and their implications for social welfare. We show that the ISP’s decision on the introduction of discrimination across content depends on a potential trade-o¤ between network access fee and the revenue from(More)
Using data from the U.S. automobile market, we empirically examine the link between competition and innovation. Consistent with a large literature, we use patent counts as a measure of innovation. The combination of the U.S. market’s economic importance, market dynamics, and the significant intertemporal fluctuations in firms’ market shares and patents make(More)
We analyze the effect of net neutrality regulation in a two-sided market framework when content is heterogeneous in its sensitivity to delivery quality. We characterize the equilibrium in a neutral network constrained to offer the same quality vis-à-vis a non-neutral network where Internet service providers (ISPs) are allowed to engage in second degree(More)
We consider competition among n sellers when each of them sells a portfolio of distinct products to a buyer having limited slots (or shelf space). We study how bundling a¤ects competition for slots. When the buyer has k number of slots, e¢ ciency requires the slots to be allocated to the best k products among all products. We …rst …nd that without bundling,(More)
Molecular recognition of protonated aliphatic polyamines has been studied at calix[4]crown-5 self-assembled monolayer modified gold electrodes by electrochemical impedance spectroscopic (EIS) experiments. The energy of complex formation between the calix [4]crown-5 molecule and a series of alkyl ammonium ions was shown by molecular modeling and EIS(More)
We study how net neutrality regulations affect a high-bandwidth content provider(CP)’s investment incentives to enhance its quality of services (QoS) in content delivery to end users. We find that the effects crucially depend on whether the CP’s entry decision is constrained by the Internet service provider (ISP)’s network capacity. With limited capacity,(More)
