Unfair prices for holiday air travel in India? Any lasting effects?

November 29, 2010

Michael Giberson

Leigh Caldwell, at Knowing and Making, notes concerns raised by representatives of India’s government about unfair airline prices during the festival of Diwali.  Caldwell mostly ignore the government’s chatter about unfair prices, but wonders how consumer reactions may influence company pricing decisions over time.  I think he offers interesting speculations, but I think that consumer price expectations won’t work in the way he thinks in the relatively dynamic air travel market in India.

The Financial Times reported (via GulfNews.com):

India’s government has warned domestic airlines that it intends to crack down on “predatory pricing” after carriers sharply increased fares on popular routes during a recent festival, as overall passenger traffic surges.

Indian travellers were outraged during the recent festival of Diwali — Hinduism’s biggest gift-giving holiday — when some carriers charged about Rs25,000 (Dh2,000) for a last-minute Delhi-Mumbai round trip ticket, a route on which fares usually range from Rs10,000-Rs15,000.

Fares on other popular routes also surged during the holiday period, as local airlines sought to cash in on a newly buoyant market.

“This predatory pricing can’t be allowed to continue,” Praful Patel, the civil aviation minister, said at an industry conference in New Delhi on Thursday. “We shall try our best to bring discipline.”

Caldwell tried to assess how consumer perceptions of price fairness will affect the market. Caldwell said:

In any case, like all suppliers, Indian airlines must keep an ear open to what their customers regard as fair, but need not pay too much attention to the protests of those who are not actually buying the tickets. Perceptions of fairness can shift quickly in consumer markets. However, new brands, services and routes have an advantage over incumbents who have been using a particular model for years. People who have never tried a newly launched airline will have no strong price expectations. While those who have used the same one for years may feel ripped off by a price increase.

The likely outcome of this dynamic is that existing airlines are under more pressure to keep prices low, and will sell out all their tickets quickly. New airlines can charge more, will mop up the excess demand and, as a result of the higher prices, may be perceived as a higher quality service. This will give them a competitive advantage when demand returns to its usual lower level from February onwards.

I’m not sure there is any lasting reputational effect at stake.  Research suggests that pioneering brands (first product in a consumer category) and long-dominant brands obtain a psychological position as a prototypical example of a product in the category.  Prices of prototypes can strongly affect price expectations for other products in the category, but prices of non-prototypes don’t strongly affect price expectations for prototypes.  But this affect is strongest in especially innovative product categories, and weaker otherwise.  I’d suspect that airlines fall into the “weaker otherwise” set.

With airline travel, consumers see many options for a relatively undifferentiated service and compare prices.  While airlines offer full-service brands and discount brands, and may further differentiate between first class and other seating, within each category consumers compare prices across companies.  In such an environment, the specific price expectations that attach to an airline brand itself (as opposed to the product category the brand participates in) are probably quite weakly held.  As the Financial Times article notes, 70 percent of air travel in India is on “low fare” carriers (including the low-fare affiliates of full service airlines).  It is a fluid, contestable market which is unlikely to support the strong, durable price reputations necessary for Caldwell’s effect to work.

Cargo bikes in Copenhagen

September 23, 2010

Michael Giberson

I could have used a Copenhagen cargo bike (see video at linked post) last year when I occasionally carried my son’s baritone horn up to school for him. Come to think of it, I could probably still make use of a cargo bike.  Better yet, my son could make use of a cargo bike!

Want more cargo biking? Here is a link to the “cargo bike culture” posts at Copenhagen Cycle Chic. Or check out the images and video at the website of Larry vs. Harry (designers/manufactures of the Bullitt cargobike).

An economic analysis of comparative fuel economy?

August 13, 2010

Lynne Kiesling

Thursday’s Wall Street Journal had an article on airline fuel economy, “A Prius With Wings vs. a Guzzler in the Clouds“, and it presents an analysis that is a good starting point for thinking about an economic comparison of the fuel efficiency of different modes of transportation. The analysis compares the fuel economy of different U.S. airlines, measured in miles per gallon to facilitate comparisons with other modes of transportation: “With airlines, it’s how far one seat (occupied or not) can travel on one gallon of jet fuel.”.

One technical caveat: the measure of m.p.g. uses the number of seats in the airline’s fleet, not the number of occupied seats. Thus if the airline has a low load factor (i.e., flies planes with lots of empty seats), then this measure will overstate their fuel economy relative to what it would be if you measured actual passenger miles flown. Motivated by competition, costs, and narrowing profit margins, though, airlines have had pretty high load factors since deregulation in 1978, so I wouldn’t throw out this analysis based on that caveat.

Two interesting results come out of the analysis. First,

The three worst major U.S. carriers for fuel efficiency happen to be the three biggest: Delta, American and United airlines. They fly the biggest planes, which aren’t always more fuel efficient, and they have the oldest fleets.

Best in fuel economy: Alaska Airlines, jetBlue Airways and Continental Airlines, which all have fleets that average nine years of age or younger. Regardless of an airline’s ranking, your particular flight mpg will vary greatly.

So newer planes are more fuel efficient, and even though larger planes can carry many more passengers, the incremental fuel burned per additional passenger is higher. I’d be interested in seeing an econometric analysis that decomposed the magnitudes of the age effect and the size effect.

Second, note that the average fuel economy for the entire U.S. air fleet is 64 m.p.g. That’s high! Even if you take into account the load factor caveat, that’s an impressive number, as is the improvement in fuel economy that the airlines have generated since 2000 (motivated, certainly, by increases in jet fuel prices and jet fuel price volatility that they can’t hedge fully).

Comparing the fuel efficiency of different modes of passenger transportation is difficult, but this recent post at truecostblog makes a thorough stab at an apples-to-apples comparison of actual passenger miles per gallon, a measure that takes into account average vehicle occupancy and actual vehicle miles traveled, not just passenger capacity. This measure will disfavor the personal car, which for most of us most of the time operates with a load factor of 25% (single drivers). Truecostblog’s results:

Each of the calculation is supported by notes, so please check the original post to get further details on the calculations.

Note here that the estimate of the airplane mpg is 42.6, with the decrease relative to the WSJ analysis reflecting the load factor of 79.6%. Passenger trains compare favorably, despite the poor utilization/load factor of Amtrak in the US. But what’s really striking here is how poorly the bus, the car, and the SUV/minivan compare to the airplane and train.

As an aside, note also that these data support all of those CSX commercials we’ve been seeing where CSX trumpets how green it is to ship freight by train rather than truck — the freight train 190.5 PMPG vs. the 18-wheeler 32.2 PMPG.

Electric vehicle recharging: Is the energy too cheap to meter?

June 24, 2010

Michael Giberson

Competitive retail power company NRG plans to offer an “all you can eat” electric vehicle recharging plan in Houston early next year, expanding the offer to the Dallas area a little later.  Likely too few electric vehicles will show up in Houston in the next year or so to make much of a dent in the retail power market, but in general electric vehicles should tend to recharge off-peak, improving the retailers power factor, and possibly tending to reduce average power costs a little.  I assume they’ve done the analysis and understand what they are doing.

Perhaps it is a tool to attract high-income consumers to NRG’s retail power unit – Reliant Energy – for home electric service? Seems a little crazy to me, but that is one of the great things about the competitive Texas retail power system: retailers can do crazy things, and no public utility commission has to approve, and no captive ratepayer can be stuck with the bill.  Competition works in mysterious ways.

National Research Council says benefits from plug-in hybrid vehicles decades away

December 17, 2009

Michael Giberson

The National Research Council has issued a study examining the costs and benefits of plug-in hybrid electric vehicles and concluding that it will likely be decades before such vehicles yield benefits to overcome their higher initial costs.  From the press release:

Costs of plug-in hybrid electric cars are high — largely due to their lithium-ion batteries — and unlikely to drastically decrease in the near future, says a new report from the National Research Council.  Costs to manufacture plug-in hybrid electric vehicles in 2010 are estimated to be as much as $18,000 more than for an equivalent conventional vehicle.  Although a mile driven on electricity is cheaper than one driven on gasoline, it will likely take several decades before the upfront costs decline enough to be offset by lifetime fuel savings.  Subsidies in the tens to hundreds of billions of dollars over that period will be needed if plug-ins are to achieve rapid penetration of the U.S. automotive market.  Even with these efforts, plug-in hybrid electric vehicles are not expected to significantly impact oil consumption or carbon emissions before 2030.

John Petersen, writing at Alt Energy Stocks, sums up the point for investors who have jumped into the field: “grid-enabled vehicles, or GEVs, are nowhere near ready for prime time and investors that buy into the GEV hype can look forward to decades of pain and suffering.”  Petersen follows up with additional commentary on electric vehicle issues.

It doesn’t appear that the NRC report examines possible “Vehicle to Grid” (V2G) services and associated revenue, which are sometimes explored in this kind of analysis, but that is probably a good thing.  You might recall the USPS report “Electrification of Delivery Vehicles” assumed that the examined all-electric vehicles would yield nearly $200 per month from V2G (and still the project only made sense of the USPS if taxpayers chipped in to the tune of $15,500 per vehicle).  The NRC report is on the safer ground, I think.  As I’ve said here before, projections of significant V2G revenues are unlikely to pan out.
