This paper surveys published economic studies and judicial decisions that contain 1,040 quantitative estimates of overcharges of hard-core cartels. The primary finding is that the median long-run overcharge for all types of cartels over all time periods is 25.0%:18.8% for domestic cartels and 31.0% for international cartels. Cartel overcharges are positively skewed, pushing the mean overcharge for all successful cartels to 43.4%. Convicted cartels are on average as equally effective at raising prices as unpunished cartels, but bid-rigging conduct does display somewhat lower mark-ups than price-fixing cartels. These findings suggest that optimal deterrence requires that monetary penalties ought to be increased.

Many jurisdictions fine illegal cartels using penalty guidelines that presume an arbitrary 10% overcharge. This article surveys more than 700 published economic studies and judicial decisions that contain 2,041 quantitative estimates of overcharges of hard-core cartels. The primary findings are: (1) the median average long-run overcharge for all types of cartels over all time periods is 23.0%; (2) the mean average is at least 49%; (3) overcharges reached their zenith in 1891–1945 and have trended downward ever since; (4) 6% of the cartel episodes are zero; (5) median overcharges of international-membership cartels are 38% higher than those of domestic cartels; (6) convicted cartels are on average 19% more effective at raising prices as unpunished cartels; (7) bid-rigging conduct displays 25% lower markups than price-fixing cartels; (8) contemporary cartels targeted by class actions have higher overcharges; and (9) when cartels operate at peak effectiveness, price changes are 60–80% higher than the whole episode. Historical penalty guidelines aimed at optimally deterring cartels are likely to be too low.

There has been increased interest in expanding the Medicare Prospective Payment System (PPS) to non-Medicare payers to provide incentives for hospitals to contain costs and to concentrate in those Diagnosis-Related Groups (DRGs) which they can provide efficiently. However, this should not force low-volume, low-cost payers to subsidize high cost payers and should not penalize low Length-of-Stay (LOS), low-cost hospitals. This article proposes a new method proportional pricing to expand PPS incentives to non-Medicare payers with equity for payers and hospitals. It would also allow all-payer rate setting and premium price competition among payers to coexist.

The study's purpose is to investigate the price volatility of four dairy commodities (skim milk powder [SMP], whole milk powder [WMP], butter and cheddar cheese) in the three most significant regional markets (EU, Oceania and US) in the international dairy market.

The study uses a panel-Generalized Autoregressive Conditional Heteroskedastic (panel-GARCH) modeling technique and data from January 12, 2001, to April 28, 2017.

Conditional volatility was higher during subperiods 2007–2010 and 2014–2016 when conditional cross-correlations between prices had the lowest values. In some cases, they were negative (i.e. between the EU and the USA and between Oceania and the USA for both butter and cheese). Interdependence across the three dairy markets, especially for SMP and WMP markets and for the butter market between EU and Oceania is also strongly evidenced. Interdependence is responsible for the spillover of price shocks across the three regions.

The data set used should be extended to cover the COVID-19 pandemic period.

This is the first study to use panel-GARCH to examine international dairy prices and volatility linkages, where previous studies mainly used multivariate GARCH models. Panel-GARCH allows a high-dimensional data series (i.e. 12 dairy prices) and generates potential efficiency gains in estimating conditional variances and covariances by incorporating information about heterogeneity across markets and considering their interdependence.

In class action antitrust litigation, the standards for acceptable economic analysis at class certification have continued to evolve. The most recent event in this evolution is the United States Supreme Court’s decision in Comcast Corp. v. Behrend, 133 S. Ct. 1435 (2013). The evolution of pre-Comcast law on this topic is presented, the Comcast decision is thoroughly assessed, as are the standards for developing reliable economic analysis. This article explains how economic evidence of both antitrust liability and damages ought to be developed in light of the teachings of Comcast, and how liability evidence can be used by economists to support a finding of common impact for certification purposes. In addition, the article addresses how statistical techniques such as averaging, price-dispersion analysis, and multiple regressions have and should be employed to establish common proof of damages.

This paper aims to examine hotel star ratings on selected third‐party distribution websites, taking Hong Kong hotels as the sample.

Star rating information from 11 online distribution websites was retrieved and analyzed for all hotels in Hong Kong.

About 60 percent of the hotels were found on at least six of the selected distribution channels, and only 24 percent of the hotels have consistent star rating across different distribution channels. Results of data analysis indicated that consistent star rating becomes more difficult to maintain as the number of distribution channels used increases.

Findings of the study are limited to the selected hotels and electronic distribution channels. Still, the online distribution channels represent some of the most widely used electronic distribution channels.

Findings of this research will be of use to hotel managers and guests for better understanding the standard, in terms of star ratings, of hotels.

Despite the importance of hotel star ratings on consumers and the hotel industry, prior studies in the existing hospitality literature rarely examined the difference of hotel stars. This novel study should, thus, make a meaningful contribution to knowledge development.

In order to enhance operational efficiency, improve service quality and reduce costs, practitioners in the hospitality industry have widely adopted and implemented information and communication technologies (ICTs) in their businesses. Understanding what has been done and how ICTs have performed in the past and are performing in the present could assist practitioners and researchers in identifying research gaps and formulating future plans. This paper aims to address these issues

This study analyzed 88 full-length ICT-related research articles that were published in the period 1999-2008 in eight leading hospitality journals. The research focuses on all selected articles were in suppliers ' perspectives, and each article was analyzed by content analysis.

Seven dimensions were formed after content analysis including human resources and training, security, reservation, revenue management, marketing, guest services, as well as strategic and operational management. Published articles were comprehensively overviewed on ICT usage in suppliers ' perspectives. In this paper, suppliers refers to the providers of hospitality services.

The major limitation of this study is the inclusion of only eight leading journals. Nevertheless, findings should be of use to researchers and practitioners to understand various ICT applications in the hospitality industry.

A major contribution of this paper is its comprehensive review of previous studies and their contributions to hospitality. Future research areas on ICT development and implementation in suppliers ' perspective are also offered.

The purpose of this paper is to explore the pricing policies that service companies adopt along with the pricing information that they gather to set their prices. Despite previous authors' suggestions regarding the need for a coherent process when setting prices, there seems to be a lack of empirically‐based theory on how pricing policies and pricing information might be interrelated.

Following 26 in‐depth exploratory interviews, additional personal interview data were collected from 170 companies operating in six different services sectors in Greece.

The paper finds that “list pricing” is the only policy that is adopted by the majority of the surveyed companies. Further, they tend to collect more than one type of information giving particular emphasis on market‐based information. The “customer‐based” information was found to be associated positively with the policy of “cash discounts”, while the “competition‐based” information with the policies of “trade discounts” and “differentiated pricing”. Moreover, the “cost‐based information” is associated positively with the “cash discounts” and “efficiency pricing” policies and negatively with the “loss leader pricing” policy.

The findings refer to the need for a “balanced” market‐oriented and “situation‐specific” approach when setting prices The significance of these findings notwithstanding, the context of the study (Greece) is the most important caveat since it limits the ability to generalize the results in other countries.

The paper represents the first attempt to examine empirically the potential relationship between pricing policies and pricing information.
