He called upon the EU to pressure Slovakia’s gas transit pipeline operator into sanctioning so-called reverse gas transit flow schemes, allowing Ukraine, which relies heavily on Russian fuel imports, to diversify by importing European market gas.

How countries calculate their GDP

Simon Kuznets, a Russian emigrant to America, is credited with creating the first true GDP estimate, for delivery to America’s Congress in 1934

Output can be measured in three (theoretically equivalent) ways: by adding up all the money spent each year, by adding up all the money earned each year, or by adding up all the value added each year. Some economies, including Britain, combine all three methods into a single GDP figure, whereas others, like America, produce different statistics for each.

A snapshot of Nigeria’s economy in 1990 gave little or no weight to fast-growing parts of the economy such as mobile telephony or the movie industry. At the time the state-owned telephone company had a few hundred thousand customers. Today the country has 120m mobile-phone subscriptions. On the old 1990 figures, the telecoms sector was less than 1% of GDP; it is now almost 9% of GDP. Motion pictures had not shown up at all in the old figures, but the industry’s size is now put at 1.4% of GDP.

The oil industry’s share of GDP is now put at just 14%, compared with 33% according to the old figures.

Europe’s dangerous addiction to Russian gas needs radical cure

“It really boils down to this: no nation should use energy to stymie a people’s aspirations,” Mr Kerry said in Brussels, just as Russia’s Gazprom raised the price it charges Ukraine for gas.

Bernstein Research has calculated that to do so, Europe needs to eliminate 15 bcm of residential and industrial gas demand, invest $215bn and incur $37bn of annual costs in the form of higher-priced energy. That works out as $160 for every single person in Europe.

How to Get a Job at Google

noted that Google had determined that “G.P.A.’s are worthless as a criteria for hiring, and test scores are worthless. ... We found that they don’t predict anything.”

“Good grades certainly don’t hurt.” Many jobs at Google require math, computing and coding skills, so if your good grades truly reflect skills in those areas that you can apply, it would be an advantage.

“I was on campus speaking to a student who was a computer science and math double major, who was thinking of shifting to an economics major because the computer science courses were too difficult. I told that student they are much better off being a B student in computer science than an A+ student in English because it signals a rigor in your thinking and a more challenging course load. That student will be one of our interns this summer.”

“She was moving out of a major where she would have been differentiated in the labor force” and “out of classes that would have made her better qualified for other jobs because of the training.”

Gross trade accounting: A transparent method to discover global value chain-related information behind official trade data: Part 1

With the rapid increase in intermediate trade flows, trade economists and policymakers have reached a near consensus that official trade statistics based on gross terms are deficient, often hiding the extent of global value chains. There is also widespread recognition among the official international statistics agencies that fragmentation of global production requires a new approach to measure trade, in particular the need to measure trade in value-added. This led the WTO and the OECD to launch a joint “Measuring Trade in Value-Added” initiative on 15 March 2012, which is designed to mainstream the production of trade in value-added statistics and make them a permanent part of the statistical landscape.

All the estimation methods used in recent efforts to measure trade in value-added are rooted in Leontief (1936). His work demonstrated that the amount and type of intermediate inputs needed in the production of one unit of output can be estimated based on the input-output structures across countries and industries.

Russia Steps Up Economic Pressure on Kiev

Russia is now asking close to $500 for 1,000 cubic meters of gas, the standard unit for gas trade in Europe, which is a price about a third higher than what Russia’s gas company, Gazprom, charges clients elsewhere. Russia says the increase is justified because it seized control of the Crimean Peninsula, where its Black Sea naval fleet is stationed, ending the need to pay rent for the Sevastopol base. The base rent had been paid in the form of a $100 per 1,000 cubic meter discount on natural gas for Ukraine’s national energy company, Naftogaz.

Mr. Yatsenyuk raised the pressing need to build an interconnector pipe allowing for a so-called reverse flow from the European Union into the Ukrainian gas system. “We need reverse flows of gas from the European Union to support Ukraine’s energy security,” Mr. Yatsenyuk said.

The Global Economy’s Tale Risks

Fluctuations in the world’s economies are largely due to the stories we hear and tell about them. These popular, emotionally relevant narratives sometimes inspire us to go out and spend, start businesses, build new factories and office buildings, and hire employees; at other times, they put fear in our hearts and impel us to sit tight, save our resources, curtail spending, and reduce risk. They either stimulate our “animal spirits” or muffle them.

The output gap for the world’s major advanced economies, as calculated by the IMF, remains disappointing, at -3.2% in 2013, which is less than half-way back to normal from 2009, the worst year of the global financial crisis, when the gap was -5.3%.

What exactly is an entrepreneur?

Schumpeterians distinguish between “replicative” entrepreneurs (who set up small businesses much like other small businesses) and “innovative” entrepreneurs (who upset and disorganise the existing way of doing things). They also distinguish between “small businesses” and “high-growth businesses” (most small businesses stay small). Both sorts have an important role in a successful economy

In a new paper Magnus Henrekson and Tino Sanandaji argue that the number of self-made billionaires a country produces provides a much better measure of its entrepreneurial vigour than the number of small businesses.
