Mobile cell phone revolution

Today, Great Britain’s The Guardian (whose readers think they ought to run the country according to Yes, Prime Minister!) highlighted the importance of cellphones for Africa’s future economic growth. Cellphones used to circulate information about prices, it allows producers to coordinate their activities more efficiently and they also permit mobile banking. In short, they reduce transaction costs and allow firms to expand their boundaries, to specialize even more and outsource some activities to other firms.

However, I am quite surprised that all the attention has gone to Africa with regards to cellphone. True, there is an ongoing “cellphone revolution” in Africa, but Guatemala is the country to look at. In the 1990s, Guatemala liberalized its telecommunications industry so as to reduce to a near zero the barriers set by the government for entry in the industry. There are now hundreds of telephone providers in Guatemala and there is an explosion in cellphone numbers.

Let us compare Guatemala with two affluent countries of Africa which are often hailed as “success stories” (Bostwana and Mauritius) and the often-mentionned country of Kenya (UN DATA). For good measure, let us also South Africa and Uganda which is mentionned in the Guardian’s article. As we can see below, Guatemala is by far the country with the most cellphones (pre-paid and post-paid) per 100 inhabitants, in fact it seems that many may in fact have two cellphones.

This is strong testimony to the benefits of liberalization of telecomms in Guatemala and that country should be the one to look at for the fullest extent of cellphones in economic growth.

 

 

Working Paper and Data : Intercity buses in Canada

In the last few months, I have been spending a whole lot of time on intercity buses between Montreal, Sherbrooke and Ottawa since I don’t possess a driver’s licence yet. Every time I had to go to the central bus station, I never had the chance of selecting which bus company I wanted to carry me to where I wanted to go. For example, between Sherbrooke and Montréal, I always have to use Transdev Limocar and there is no chance to choose Megabus, Greyhound or Orléans. Between Ottawa and Montréal, I always have to use Greyhound, I have never been offered to take a Orléans or Megabus.

This got me thinking about my time in England and in the United States. In both countries, I travelled between large urban centers and had the chance to select between a whole score of carriers. Case of point, when I was living in D.C., I deliberated between buying a bus ticket to New York with Greyhound where I would have had free wifi and more legspace at a higher price than a Chinatown-based company-whose-name-I-cannot-remember where I knew I would not be as confortable as with Greyhound.

Why do we have so few choices in Canada (at least in Quebec)? It seems that regulatory schemes in most provinces intends us to have few choices. Indeed, in many provinces a licence to operate a profitable route will be granted by the regulatory authorities to a given carrier in exchange that he provides services on less profitable lines.

A 2002 report by the Canadian Senate noted that this system of cross-subsidization had quite detrimental effects on consumers because it imposed higher prices to the vast majority of Canadians while also shielding bus operators from market pressures to become more efficient and more innovative.

This is why I have collected price for 27 lines in Canada in all provinces by 8 providers (Megabus, Acadian, Orléans, Greyhound, Intercar, Transdev Limocar, Malaspina Bus Lines and the Saskatchewan Transportation Company). I have collected the data online on the websites of these various companies during the month of July according to the scenario of a one-way trip on July 29th. I have taken the lowest price and the highest price available to compare price ranges. All of the tickets are for an adult passenger, no discounts for students, military or aboriginals have been taken into consideration. Moreover, I have elected not to take refundable fares since Greyhound Canada did offer that service while other firms do not. Every website mentions the estimated travel time, so I have divided both the lowest price and the highest by the lowest estimated time. This gave me a price per minute of travel which I could then compare with other countries. I have also collected data for 19 lines in the United Kingdom from 3 different providers and for 26 lines in the United States from 6 different providers. In these two countries, the intercity bus industry has been deregulated (and privatized in the case of the UK) since the eighties. This is why I chose to compare Canada with those two countries.

All the hypothetical transactions were evaluated on July 4th 2011 for the UK and the US and the exchange rate used is the one provided by XE Currency Converter. It is likely that that several companies were not counted since they do not make their prices known online. Below is the result of the data, however I will not publish the entire dataset yet since I intend to make a working paper at the very least and if possible, get it published in a academic journal. So please, be patient until I try and publish the paper.

Calorie Intake in Germany during World War II

Continuing with data series regarding World War II, I have found this data set (still in McNab’s fascinating book) concerning the daily intake of food derived from the ration tickets emitted. Even if I reproduce this data here, I might venture a word of warning regarding the “food intake” in this case. It concerns only “german” civilian and not the vast population of slave labourers forced to toil under the yoke of the Nazis. Let us remember that in January 1945, there were 6,691,200 individuals working in Germany as slaves (including prisoners of wars and political prisonners). This included all the “races” which the Nazis considered as inferior (Balts, Russians, Yugoslaves, Jews, Gypsies, Czechoslovaks, Ukrainians and Poles) who died in greater numbers than their French, Belgians, Dutch, English or Italians counterparts due to intentional malnourishment by the Nazis.  It seems reasonable to assert that the real food intake for all individuals within the Third Reich during World War II was considerably lower than those reported in the data below.

Note also that McNab mentions that the prewar calorie intake was close to 3,000 kcals per day.

Bombs dropped on Germany during World War II

In my quest to continue to provide data to military historian in ways that are easily accessible to them, I am publishing a new data set regarding World War II. In Chris McNab’s 2009 book on the Third Reich, there are so many data series available that I feel compelled to share them, starting by this figure about the tonnage of bombs dropped on Germany by the Royal Air Force and the United States of America’s Air Force.
