Price-match guarantees and investment incentives

We study how price-match guarantees affect the incentives of both firms to invest in cost reduction and quality enhancement. We find that price-match guarantees in our model weaken these incentives in most cases. Our research reveals more reasons to suspect that seemingly pro-competitive price-matching by many offline rivals to online sellers may have hidden social costs.

The Impact of Uber and Lyft on Taxi Service Quality: Evidence from New York City

SSRN Electronic Journal, 2018

Using detailed trip-level taxi and for-hire-vehicle data and new incident-level complaints data, ... more Using detailed trip-level taxi and for-hire-vehicle data and new incident-level complaints data, we study how the entry of Uber and Lyft has affected the quality of taxi services in New York City. In a panel setting with 263 NYC taxi-zones over the time period from 2014 to 2017, we find that increased competition measured by the number of daily Uber/Lyft trips in a given taxi-zone has led to more complaints regarding a variety of service quality dimensions such as unsafe driving, rude behavior and fare refusal. Our results are robust to accounting for potential simultaneity in the determination of complaints and Uber and Lyft penetration.

Digital traffic controller on the Altium NanoBoard

2012 International Symposium on Communications and Information Technologies (ISCIT), 2012

An approach is proposed for the design and implementation of traffic light controllers using FPGAs. The focus of this study is to develop an effective traffic signalling strategy to be implemented at a typical intersection. The hardware and software development platform used for final implementation is the Altium NanoBoard 3000 Xilinx Edition, along with the Altium Designer package. The NanoBoard 3000 was newly released from Altium and it provided a convenient FPGA platform and all the necessary IP, IP Synthesis, and compilers needed to prototype the design and perform further research.

Time has come for this to be introduced in Pakistan for all its Academic, Research and Practical reasons pertaining to Justice System & Crime. Its significance in terms of reporting, sharing scientific evidence, handling Crime is influenced by the people who are properly Qualified and trained as Forensic Odontologists and unfortunately we have none. As our society is rapidly changing, becoming more commercial & losing its cultural, ethical & human touch, therefore we feel it is high time for this neglected Dental Specialty to be given birth-introduced as we aim for National Paradigm Shift and share this Presentation.
