General drug prices involve three stages: shipment stage, wholesaler stage and retail stage. Policies on drug price differ from country to country. Shipment stage prices are tightly regulated in countries like France and Netherlands. They are free in only a minority of advanced countries, even if these include some major players such as the US, Germany and, in a very limited sense, Japan. The situation in the UK is very complex with a semi-free system, where drug companies are free to set their own prices but cannot exceed a predetermined profit ceiling. Mark-up at both wholesaler and retail stages is formally admitted in most countries observed. Apart from the general drug prices, reimbursement price of insured drugs has been major policy concerns. Most countries reviewed in this study has exerted some control over reimbursement prices, but differ both in the way how and in the extent to which prices are admitted or fixed. Price fixing has been used in France and Japan. Some countries have transformed their system over time, particularly to move to reference pricing in the last decade. This mechanism has empowered the customer, and improved price competition on the market. Referring to the drug price policies in the advanced countries, this study makes some suggestions for the redirection of Korean price policy for reimbursement drug in health insurance as follows: to match appropriate policy tools to each policy goal; to maximize market mechanism through effective reimbursement price fixing which admits mark-ups in wholesaler and retail prices; to introduce reference pricing system in order to redirect patient's demand with a financial incentive to choose the best-priced drugs and to save the finance of health insurance; and to strengthen surveillance and monitoring mechanism in the drug market.

We present key issues to consider in estimating damages from price-fixing cases and then apply the procedure addressing those issues to a transportation fuel market. Among the five methods of overcharge calculation, the regression analysis incorporating the yardstick method is the best. If the price equation relates the domestic price to the foreign price and the exchange rate as in the transportation fuel market, the functional form satisfying both logical consistency and modeling flexibility is the log-log functional form. If the data under analysis is of time series in nature, then the ARDL model should be the base model for each market and the regression analysis incorporating the yardstick method combines these ARDL equations to account for inter-market correlation and arrange constant terms and collusion-period dummies across component equations appropriately so as to identify the overcharge parameter. We propose a two-step test for the benchmarked market: (a) conduct market-by-market Spearman or Kendall test for randomness of the individual market price series first and (b) then conduct across-market Friedman test for homogeneity of the market price series. Statistical significance is the minimal requirement to establish the alleged proposition in the world of uncertainty. Between the sensitivity analysis and the model selection process for the best fitting model, the latter is far more important in the economic analysis of damage in price-fixing litigation. We applied our framework to a transportation fuel market and could not reject the null hypothesis of no overcharge.

In the steel industry, there is a perception that "collusion has become a long-standing practice" and it is expected that the authorities' legal response to collusion will be strengthened in the future. This necessarily requires improving the accuracy of the legal response, the most important of which is to accurately identify whether the allegedly colluding firms actually did collude. This study focuses on the recent iron scrap price-fixing case and examines whether a single accused firm actually engaged in price-fixing in a situation where there is a mix of firms that acted independently of the collusion and firms that actually engaged in price-fixing. The results of the analysis allow us to infer that the accused steelmaker did not actually collude, which is consistent with the authorities' final judgment against the steelmaker. In the real world, some collusions are carried out by only a subset of firms in a market, and in these cases, there are often disputed firms as to whether or not they carried out the collusion. This study can serve as an analytic guide for industries, including the steel industry, to verify the behavior of individual firms, especially those whose collusive practices are disputed.

There has never been research on Chaos analysis using real estate auction sale price rate in Korea. In this study, three Chaos analysis methodologies - Hurst exponent, correlation dimension, and maximum Lyapunov exponent - in order to capture the nonlinear deterministic dynamic system characteristics. High level of Hurst exponent and the extremely low maximum Lyapunov exponent provide the tendency and the persistence of the data. The empirical results give two meaningful facts. First, monthly time lags of the correlation dimension are coincident with the time period from the approval auction start day to the sale price fixing day. Second, its weekly time lags correspond to the time period from the last day of request for sale price allocation to the sale price fixing day. Then, this study potentially examines the predictability of the real estate auction price rate time series.

The price systems of the hospital drug services play key roles in the provision of quality services and the development of pharmacy service technologies. Under the premises, this study attempted to determine the costs of hospital drug service, to compare the costs calculated with the fees publicly fixed by the Government, and based on the results of the analysis, to propose directions for the improvement of the price systems. A Costing model for the study was developed based on the cost-fee relationship analysed of the Korean fee-for-service systems. Data on costs and workloads of the 25 hospitals were collected through survey forms designed for the costing' and analysis for the duration of 12 months of 1998. The results of the analysis show that a tremendous unbalance between cost and price levels of the drug services, and that overally the price level of the services is extremely low when compared to the costs of services. Based on these findings, this study suggests that unfairly high or low price level be corrected, and that service items newly developed and being practiced at tertiary hospitals, such as TDM and TPN consultation services, be compensated by fixing a proper level of price.

Metropolitan Subway, tke volume of station, distance between station is short. when the demand is concentrated during moving peak periods, the Headway that than Line Headway in which Station Headway is applied to Station Capacity computation be. The factors to determine the Station Headway have a fixing Price of the machine and the Dwell time. Other factors aye decided already or fixing price but the Dwell time that change according to demand cause the biggest effect at Station Headway. After analyze constituents that influence to Station Headway in this study calculated correct Station Capacity drawing estimating dwell time model that change according to demand.

This study examines whether there are differences in consumer's evaluation price zone on the clothing clue (the type of clothing, brand, time of fashion, place of origin, material. submaterial, place for sale) according to consumer purchasing behavior. Therefore the ultimate goal is to offer help in fixing price when establishing marketing of the clothing industry by grasping the actual price set by consumers under the IMP system. The female consumers of 20s and 30s were chosen as study subjects for their sensitivity to the purchase of clothing. The tests carried out in this research are: SPSSIPC+ is used for frequency Analysis. The Results of this study are showed as the following: It was analyzed that 4 types of consumer are the reasonable consumption oriented consumer, fashion oriented consumer, the no care of fashion consumer and high price oriented consumer Among the several kinds such as the type of clothing, brand, time of fashion, place of origin, material, submaterial, place for sale, only on the type of clothing, there are difference in the type of the consumers, on the time of buying clothes, in the behavior of buying clothes and also on the degree of fashion and the place of origin among such kinds.

사업자간의 협정이 법률상 명백하게 카르텔에 해당하는 경우에는 이를 엄격하게 규제하여야 할 것이나 이의 법률상 요건이 성숙되지 않은 경우에 이를 규제하는 것은 규제가 오히려 실패할 가능성이 있다는 점에서 카르텔의 성립요건 중 확인할 사항은 충분하게 확인하여야 할 것이고 법리에 보다 충실하게 적용하여 규제하여야 할 것이다. 또한 공모를 직접 입증할 수 없는 경우에도 단순하게 당해 시장에서의 공동행위 참여자의 시장점유율에 의한 경쟁제한성과 참여자 상호간의 경쟁제한성만의 요건 충족으로 위법성을 인정하는 것이 종래의 위법성 판단방법이었으나 시장에 따라 다양한 요소를 고려하는 것이 필요하며, 경제학적인 요소를 계량화한 법적 판단기준을 확립하는 것이 필요하다.

This study reviews maritime transport policy regarding liner conference and the changes in the liner market over the decades. Liner shipping industry has long been protected from competition by block exemption. To prevent excessive competition in punctual operation and its inelastic market structure, liner shipping companies formed conferences that are protected to fix the prices under the law. In the US, deregulation in transport sector began from 80's and continuing with OSRA 1998, conferences were dissolving. On the other hand, the EU with close conference system, Regulation 4056/86 contained block exemption remained in force for unlimited time without review clause. However, in Oct 2008, the EU has announced its removal, and conferences were no longer permitted to fix the price nor exchange information. Although OSRA 1998 has already broken up conferences by allowing individual service contracts, but the repeal of the immunity for price fixing will alter significantly the rule on cooperation in the industry since it is a unilateral move by the EU, especially in transatlantic lane. There are rapid changes in shipping market getting much more complicated, and with removal of 4056/86 allowing the market to be more competitive, opening up the industry with far more diverse strategic options. Hence this paper reviews on liner shipping industry and its changes of policies over the years from protected market to open competition market of today.

In recent years, the line of increase in policy on tobacco production triggered a rise in the loading volume per bulk curing barn, and manufacturers boosted the output of their blowers in order to prevent dirty leaves in the process of curing. for this reason, we studied the effect of the reducing air flow in bulk curing chamber from the color fixing stage to the stem drying stage of flue curing process on physical properties of cured leaves. The control of air flow was composed of the reducing air velocity of blower by means of a voltage regulator (slidac), and condition before color fixing stage was all the same with the conventional curing method. As a result, an effectiveness of improvement in the physical properties of cured leaves were observed. The leaves cured by this method were somewhat orange in color of upper stalk position, better bodied, and less brittle compared with the leaves produced by conventional curing. However, the leaves cured by this method had a little sharpness and harshness. As to the physical properties, there was decreased in occurrence of flat leaves than that of conventional ones. On the other hand, in case of reducing air flow during the curing process, increase of price per kg reached to about 5 % compared with those of conventional curing method.
