This article examines whether price discrimination affects consumer price perceptions and emotions. Questionnaires involving various purchasing scenarios indicate that all kinds of price discrimination decrease the internal reference price of those who have to pay the original (higher) price. These effects of price discrimination on consumers¡¦ internal reference price are moderated by the discount depth. The deeper discount that the seller offers to the consumers, the larger the internal reference decreases. Further, when subjects were told that there is one consumer buy the product or service at the lower price (enjoying the price discount), they have negative emotion if they can have spend time looking for price-off coupons. But the other price discrimination such as VIP discount does not elicit consumers¡¦ negative emotion.

In this paper we first show that the gains achievable by integrating pricing and inventory control are usually small for classical demand functions. We then introduce reference price models and demonstrate that for this class of demand functions the benefits of integration with inventory control are substantially increased due to the price dynamics. We also provide some analytical results for this more complex model. We thus conclude that integrated pricing/inventory models could repeat the success of revenue management in practice if reference price effects are included in the demand model and the properties of this new model are better understood.

Usually, consumers will collect market information about the product before they decide to buy it or not. In other words, the market information is a critical factor to affect consumers¡¦ purchasing intensions and behavior. Previous research points out that when consumers encounter a wider dispersion of price, they will expect to find cheaper stores. Besides, future price is often considered by consumers too. Kauffman et al. (2002) mentioned that the market price information might affect the recruiting of group buying. In a competitive market, if consumers are unable to perceive the utility of discounts provided by group-buying mechanism, they may shop at other retailers¡¦ stores. Further, because the final price of group buying will not be known until the transaction is closed, consumers¡¦ decisions might be up to their prediction about the final price. This study explores how price dispersion and price volatility affect consumers¡¦ internal reference price and expectation of final price of group buying. The difference between the internal reference and expectation of final price of group-buying indicates the consumers¡¦ transaction utility. How transaction utility affects consumers¡¦ intentions to join group buying is another issue being studied. In addition, if there is interference effect of consumers¡¦ risk attitude on final price forecast of group-buying, it¡¦s investigated, too. The result indicates that price dispersion has significant effects on consumers¡¦ all kinds of internal reference prices and predictions about the final price of group buying. However, the price volatility only has significant effects on consumers¡¦ perceived fair price, aspiration price, and reservation price. Neither significant effect of price volatility on consumers¡¦ price prediction of group buying nor interference effect of risk attitude is found. As expected, there is a significant positive causal relationship between transaction utility and intention to join group-buying. It shows that the transaction utility resulting from the comparison between the lowest market price and the most possible final price of group buying has the most explanatory power to predict consumers¡¦ participating intension to join group-buying.

The feature of group buying is that the price will go down as the accumulated orders are increasing. However, consumers will not know the final price until the end. As a result, consumers can only make decision based on the final price forecast of group buying. The final price forecast might be different depending on different pricing strategies of group-buying models and if there are competitions from posted-price stores. The purpose of this research is to understand how consumers¡¦ internal reference price and final price prediction of group buying would be influenced when facing different price curves in different market competition environment. The difference between the internal reference price and final price prediction of group-buying indicates the consumers¡¦ transaction utility. In addition, if consumers¡¦ perceived transaction utilities affect their intentions and behavior of joining group buying is another research purpose. In this research, there are three different pricing strategies, decreasing, neutral, and increasing based on the initial price, discount size and final price. For the market competition environment, it manipulated by if there are other posted-price stores to be chosen or not. The research result indicates that increasing price curve, which has higher final price, make consumers¡¦ final price prediction of group buying higher than the others under the best condition. On the other hand, it indicates that decreasing price curve, which has higher initial price, make consumers¡¦ final price prediction of group buying higher than the others under the worst condition. Consumers¡¦ internal reference prices are mainly influenced by market price information. When there are other posted-price stores to be chosen, consumers¡¦ internal reference price are higher averagely. In addition, the higher consumers¡¦ perceived transaction utilities are, the higher consumers¡¦ intentions to join group buying are. Finally, it shows consumers¡¦ intentions to join group buying have significant effect on their actual behavior.

Objective: To compare statins according to the pharmacokinetic and pharmacodynamic characteristics within the drug class and to perform the comprehensive analysis of statins consumption in Lithuania between 2005 and 2007 years. Methods: MEDLINE database was searched to identify and evaluate all literature relating to pharmacokinetic and pharmacodynamic chareacteristics of statins. The statins sales data on units and wholesale prices in all Lithuanian regions over three years (2005 – 2007) were obtained from SoftDent, JSC database. Drugs were classified according to the Anatomic Therapeutic Chemical system and use was quantified in terms of defined daily doses. The consumption of statins was calculated by DDD methodology and expressed as DDD per 1.000 inhabitants per day. Expenditures were calculated using retail drug costs noted in basic price catalogue for reimbursement medicines, for each year separately. Pharmacoeconomic calculations were done according to cost minimization and reference price methodologies. Results: According to meta-analysis, Nice (2006 years) recommendations and clinical trials data statins are therapeutically equivalent medicines. The total consumption of these drugs increased from 3.9 DDD/1000 inhabitants/day in 2005 and reached the value 8.4 DDD/1000 inhabitants/day in 2007 in Lithuania, so the total consumption of statins increased by 53.6% over three years (2005 – 2007) period. Comparing with statins consumption in other countries, this meaning...

Metodai: Duomenys apie statinų farmakokinetines ir farmakodinamines savybes buvo surinkti iš MEDLINE elektroninių duomenų šaltinių. Duomenys apie statinų pardavimus vienetais ir didmeninėmis kainomis Lietuvoje per 2005 – 2007 metus gauti iš UAB SoftDent duomenų bazės. Vaistai buvo suklasifikuoti pagal anatominę terapinę cheminę (ATC) klasifikaciją. Statinų suvartojimas buvo vertinamas pagal apibrėžtos dienos dozės (DDD – daily defined dose) metodiką, o duomenys įvertinti pagal DDD skaičių, tenkantį 1000 gyventojų per vieną dieną. Išlaidos statinams buvo suskaičiuotos mažmeninėmis kainomis, remiantis kiekvienų metų kompensuojamųjų vaistų bazinių kainų kainynu. Statinų farmakoekonominei analizei atlikti buvo taikytas kainų mažinimo bei referentinės kainos nustatymo principas. Rezultatai: Remiantis metaanalizių, Nice (2006 metų) rekomendacijų ir klinikinių tyrimų duomenimis galima teigti, kad statinai prilygsta vienas kitam klinikiniu poveikiu. Bendras statinų suvartojimas padidėjo nuo 3,9 DDD/tūkstančiui gyventojų/dieną 2005 metais iki 8,4 DDD/tūkstančiui gyventojų/dieną 2007metais, taigi, per trejus metus bendras šių vaistų suvartojimas išaugo 53,6%. Palyginus su kitų šalių duomenimis, statinų suvartojimas 2007 metais Lietuvoje buvo apie 20 kartų mažesnis. Išlaidos statinams per trejus metus ( 2... [toliau žr. visą tekstą]

In many firms the pricing and inventory control functions are separated. However, a number of theoretical models suggest a joint determination of inventory levels and prices, as prices also affect stocking risks. In this work, we address the problem of simultaneously determining a pricing and inventory replenishment strategy under reference price effects. This reference price effect models the empirically well established fact that consumers not only react sensitively to the current price, but also to deviations from a reference price formed on the basis of past purchases. The current price is then perceived as a discount or surcharge relative to this reference price. Thus, immediate effects of price reductions on profits have to be weighted against the resulting losses in future periods. We study how the additional dynamics of the consumers' willingness to pay affect an optimal pricing and inventory control model and whether a simple policy such as a base-stock-list-price policy holds in such a setting. For a one-period planning horizon we analytically prove the optimality of a base-stock-list-price policy with respect to the reference price under general conditions. We then extend this result to the two-period time horizon for the linear and loss-neutral demand function and to the multi-period case under even more restrictive assumptions. However, numerical simulations suggest that a base-stock-list-price policy is also optimal for the multi-period setting under more general conditions. We furthermore show by numerical investigations that the presence of reference price effects decreases the incentive for price discounts to deal with overstocked situations. Moreover, we find that the potential benefits from simultaneously determining optimal prices and stocking quantities compared to a sequential procedure can increase considerably, when reference price effects are included in the model. This makes an integration of pricing and inventory control with reference price effects by all means worth the effort. (author's abstract)

In recent years, as the economy in Taiwan grown strongly, the lifestyles changed into a modern pattern, which had placed the traditional society. In the new, fashion, and modern lifestyles, here comes a new type of consumption. In order to adapt the new environment, marketers have developed many kinds of marketing skills to promote the services or products they provide. Therefore, sales promotions have been significantly over the years. Sales promotions are short-term incentives to encourage customers to make a purchase. As consumers are exposed to the sales promotions, their perceptions of the sales promotions play an important role in leading consumers to make purchase decisions. In sum, the purpose of this research is to discuss the relation between sales promotions and the purchase likelihood; we also try to explain how the cognition from consumers impacts their purchase likelihood. Thus, the following are our purpose: 1. To evaluate whether the sales promotions from Watsons can affect the quality perception of consumers. 2. To understand the relation between the internal reference price and perceived transaction value. 3. To analyze the relation between perceived acquisition value and purchase likelihood 4. To explore how the purchase likelihood change when the anticipation of sales promotions fail. 5. Discuss the differences of cognition toward sales promotions in Watson within genders. In this research, I administered a questionnaire to explore the data from 223 participants. The findings are as followed: 1. The sales promotions from Watsons have significant impacts on quality perception of consumers. 2. Consumers¡¦ internal reference price has significant impacts on perceived transaction value. 3. Perceived acquisition value have significant impacts on purchase likelihood 4. The failure of anticipation toward the sales promotion will decrease consumers¡¦ purchase likelihood. 5. There¡¦s no difference of cognition toward sales promotions within genders.

Product line extension is considered a low-cost, low-risk strategy of introducing products under the same category. Under product line extension strategy, however, manufactures and retailers usually advertise merely one product during a certain period, rather than advertising all products within the product line at the same time. Taking example of Coke Cola, it keeps extending its product line horizontally in the past years. There are Classic, Diet and Zero Coke belonging to the main product line. As we observed, Coke Cola seldom advertised for three products simultaneously. On the contrary, to highly impress consumers, only one product would be strongly promoted in a certain period. What is interesting is whether the advertisement of Zero Coke lowers the price that Classic Coke buyers are prepared to pay toward Classic Coke while zero calorie is highly emphasized in ads. It would be interesting to investigate the impact of product line advertisement on consumers to see whether the product line advertisement always brings positive influence on reference price toward consumers with different purchase purposes. This research addressed the question of how product-line advertisement influences consumer¡¦s reference price within vertical and horizontal product line. It combined the research of product line extension and the concept of reference price to give advice for marketing. The category of product used in experiment is durable that was suggested in prior study. To examine the relationship between product-line advertisement and reference price, experimental method was performed here to test different kind of product line advertisement toward consumers with different purpose purposes, buying high-end product, low-end product or one certain product belonging to the horizontal product line. The results indicated that within the vertical product line, the brand advertisement with low-end product decreases the reference price toward high-end product buyers whereas the informational advertisement with low-end product increases the reference price toward high-end product buyers. Besides, within the horizontal product line, both of the brand and informational advertisement with one certain product in horizontal product line decreases the reference price toward the buyer who would like to buy another product belonging to the same product line.
