Chen and Goelfeb provide insights into the life and experiences that led Ukrainian immigrant Jan Koum to found startup WhatsApp. After taking a break from work at Yahoo he decided to travel places including Argentina, where he found it especially difficult to communicate with friends in other countries by phone and messaging. The messaging service was a response to this desperately felt need on his own travels, leading to the conviction that it was best to offer it free and make it easy and convenient to use.

Manjoo provides an informative account of why WhatsApp became popular. The site started out in 2009 as a mobile status updating app. The site's founders realized after its introduction that users were using it for sending texts without incurring SMS fees. After the initial cost of a data plan and a smart phone the band width used by thousands of messages is so small it costs pennies compared to a AT&T non-plan rate of 20 cents a minute. It is this pricing gap that opened up opportunities for WhatsApp as a messaging app that is practically free, 99 cents to sign up and 99 cents for the second year on. The founders were savvy to know that ads annoyed users and kept it ad free. And they made it fast and efficient to use which accounts for estimated 450 million users worldwide in 4-5 years since 2009.

Facebook's acquisition of WhatsApp for $19 billion in cash and stock. Whats App has attracted users by offering the messaging service free and 99 cents for the second year for sending apps and pictures. It has grown rapidly in its international user base, and has in the space of 4 years since starting up in 2009 built a user base of 450 million users. About 70% of users go to the site daily compared to 61% for Facebook. Facebook pays $40 per user similiar to what is paid out for other social media sites. The main advantages are to protect Facebook as the trendiness of Facebook declines- if youngers cool to the site- by adding a popular messaging site, the international base of users, and the large number of users. A Ukrainian Jan Koum, who worked for 10 years at Yahoo, and Brian Acton founded WhatApp.

Discussion at a U.S. Fed meeting in Jan 28-29, 2014, as revealed in the minutes for that meeting. It shows Fed officials such as Bullard of the St Louis Fed asked for a debate on interest rates, but most Fed oficials at the meeting including Lockhart of the Atlanta Fed, supported current tapering policy to wind down bond purchases buy the end of 2014. Some of the discussion went to how fast the unemployment rate had declined from 7.9% to the 6.5% threshold set by the Fed, and what this meant as other signs show weakness in the U.S. economy. The drop in the unemployment rate reflected more older workers retiring and to an unusual degree discouraged workers dropping out and not looking for work. Should the Fed put more weight on inflation and financial stability some officials argued, especially as inflation was still about a percentage point below the 2% target by some estimates.
