Endogenous Price Commitment, Sticky and Leadership Pricing: Evidence from the Italian Petrol Market

This article studies dynamic pricing strategies in the Italian gasoline market before and after the market leader unilaterally announced its commitment to adopt a sticky-pricing policy. Using daily Italian firm level prices and weekly average EU prices, we show that the effect of the new policy was twofold. First, it facilitated price alignment and coordination on price changes. After the policy change, the observed pricing pattern shifted from cost-based to sticky-leadership pricing. Second, using a dif-in-dif estimation and a synthetic control group, we show that the causal effect of the new policy was to significantly increase prices through sticky-leadership pricing. Our paper highlights the importance of price-commitment by a large firm in order to sustain (tacit) collusion

Non-linearities in mark-up on costs

Abstract This study employs an error-correction SETAR model to analyse the non-linearities in the behaviour of the mark-up on costs charged by the filling stations in the New York metropolitan area. While usual price transmission gained significant attention in the literature, the mark-up portion of the price has not been analysed to date. The results indicate that the adjustment to mark-ups to their long run values is non-linear, but the speeds with they adjust to their long-run values are equal across regimes for two out of three series analysed. For one of the series the adjustment is beneficial for the end consumers such that prices fall faster than they rise. The findings are somewhat surprising, indicating that there is no need for government intervention in the NY petroleum market.Rockets and feathers; asymmetry; petroleum; SETAR

Do daily retail gasoline prices adjust asymmetrically?

This paper analyzes adjustments in the Dutch retail gasoline prices. We estimate an error correction model on changes in the daily retail price for gasoline (taxes excluded) for the period 1996-2004 taking care of volatility clustering by estimating an EGARCH model. It turns out the volatility process is asymmetrical: an unexpected increase in the producer price has a larger effect on the variance of the producer price than an unexpected decrease. We do not find evidence for amount asymmetry, either for the long run or for the short run. However, there is a faster reaction to upward changes in spot prices than to downward changes in spot prices. This implies timing or pattern asymmetry. This asymmetry starts three days after the change in the spot price and lasts for four days.

Singapore Information Sector: A Study Using Input-Output Table

The paper measures the impact of information technology on the output growth of Singapore economy. A vibrant information sector will play an important catalytic role in developing Singapore into a knowledge-based economy. The analysis provided in the paper support the assertion that information economy will be a precursor to a knowledge-based economy. The information sector grew in tandem with the expansion of export in the first half of the 1990s. By the second half of the 1990s, it developed sufficient momentum and capability to expand domestically as a cluster. The use of ICT as intermediate input is found to be generally pervasive in the economy. The paper also investigated the impact of falling prices of information input on sectoral GDP. It is found that for a 10% decrease in information input prices, the sector GDPs had to increase by 0.05% to 2.2%. The overall impact for the economy is a positive 0.84% increase in national income (GDP) for a 10% decline in information input prices.

One more lie: the Monday effect in Spain’s retail petrol market

Empirical evidence drawn from the economic literature points to a low level of competition in the retail petrol market. Similar evidence can be found for the Spanish market. In fact, both Spain’s antitrust authority -Comisión Nacional de la Competencia- and its energy regulator -Comisión Nacional de la Energía- have recently initiated disciplinary proceedings against the majors on the grounds of suspected price manipulation in the retail petrol market. They are accused of cutting retail prices on Mondays so as to distort the rank position of Spain in European Union statistics in a practice that has received the name of the Monday effect. Here, we analyze this effect by constructing a database that includes daily retail prices for all petrol stations in Spain in the period 2009-2012, and a more detailed database for the city of Barcelona in 2013. Our estimations confirm that: 1- in 2011 and 2012 prices fell on Mondays at retailers branded by majors; 2- prices were unchanged at stations in our two control groups; 3- prices were also seen to fall when a more detailed analysis was conducted, and this price cut was also found in 2013. In short, one more indicator of collusion in this sector and … one more lie

Do classes of gas stations contribute differently to fuel prices? Evidence to foster effective competition in Spain

Despite the relatively large number of gas stations reached in Spain after decades of sectorial reforms, pre-tax fuel prices in the country remain systematically among the highest in the EU. The literature provides evidence suggesting that a low intensity of competition in the retail distribution could contribute to these casual observations. With the purpose of shedding light on ways to design e↵ective competition measures, we conduct an empirical analysis of more than ten million observations containing information about prices, brands, and locations at the station level. This allows us to know whether the exit (entry) of some classes of stations have the ability to reduce the prices of nearby competitors. Our results suggest that the presence in a local market of a station belonging to the network of the dominant market companies will tend to generate prices above the average. This is not only because these stations set higher prices but also because their presence will give rise to overpricing by local competitors. The opposite occurs with the self-advertised as “low-cost” stations. Policy measures promoting the gradual exit of stations associated with the dominant companies seem quite reasonable in view of the commitment to the transition toward transport decarbonization

Price cycles in Perth petrol markets: A spectral analysis

Numerous commentators have noted the tendency of retail petroleum prices to cycle. This paper undertakes a formal analysis of petroleum price cycles, using spectral analysis to uncover which cycles are most important, and regression analysis to ascertain what drives that importance

Gasoline prices jump up on Mondays: An outcome of aggressive competition?

This paper examines Norwegian gasoline pump prices using daily station-specific observations from March 2003 to March 2006. Whereas studies that have analyzed similar price cycles in other countries find support for the Edgeworth cycle theory (Maskin and Tirole, 1988), we demonstrate that Norwegian gasoline price cycles involve a form of coordinated behavior. Retail gasoline prices follow a fixed weekly pattern, where retail outlets all over Norway simultaneously increase their prices to the same level every Monday at noon. Consequently, the sharp price increase is tied to time rather than the current price level. The gasoline companies’ headquarters publish a recommended price that de facto is a RPM arrangement towards the retail outlets. The vertical arrangement is industry-wide adopted, and is used to coordinate the time and the level for retail price increases among the big four gasoline companies. Monday changed from being the low-price day to becoming the high-price day almost ‘overnight’ in April 2004, and we empirically establish that the change corresponds to a significant jump in the gross margin.Gasoline Prices; Resale Price Maintenance

Pay cycles and fuel price : a quasi experimental approach

This paper studies the daily price fixing behaviour of the Spanish fuel stations. Using a difference-in-differences approach, we show that low-cost and independent operators take advantage of needier consumers. Their prices increase on the day the unemployed workers receive their subsidy from the government, whereas, on the same day, branded companies decrease their prices. Retailers, aware of this, raise the price when they know demand increases. This phenomenon emphasises the effect of pay cycles on consumer choices and their related economic impact. Findings are also relevant for Antitrust authorities which generally focus on the activities of major brands’ stations
