387 R ecent increases in international oil prices have resulted in substantial fuel subsidies in many developing and emerging market economies. After a long period of stability over the last two decades, international oil prices increased substantially from 2002. Prices increased from around US$25 per barrel in January 2003 to over US$65 per barrel by August 2005, an increase of about 260 perce...

In many over-the-counter asset markets, prices are negotiated bilaterally and bargaining over prices takes time. We show that bargaining delays arise when investors have precise private information about the asset quality, but the public information (e.g. credit ratings, benchmarks, past quotes) is coarse. We incorporate this type of bargaining delays into the standard dynamic equilibrium model...

Few studies have looked at the prices of essential medicines in low- and middle-income countries in terms of patient affordability. AIM To determine the prices, availability and affordability of medicines along the supply chain in Swaziland. SETTING Private- and public-sector facilities i...

Using prices of hospital admissions and visits to five types of physicians, we analyzed how provider and insurer market concentration-as measured by the Herfindahl-Hirschman Index (HHI)-interact and are correlated with prices. We found evidence that in the range of the Department of Justice's and Federal Trade Commission's definition of a moderately concentrated market (HHI of 1,500-2,500), ins...

We compared the performance of Organon Teknika's NucliSens and Roche Diagnostic Systems' Monitor quantitative human immunodeficiency type 1 RNA assays. Both had similar linearity and sensitivity over most of the dynamic range of the assays, although the Monitor assay was superior at the low range of RNA values while the NucliSens assay was more consistent at higher RNA values. NucliSens general...

Candle stick bars contain only the first, highest, lowest, and last value of a time series of dozens or thousands of data (see Figure 1). Therefore candle sticks bars are a data compression tool. Mr. Homma in Sakata, Japan, introduced candle stick bars for trading rice around 1850 [1]. The Western version of the candle stick bar is the Open-High-Low-Close bar (OHLC bar). It is commonly used to ...

We examined the 52-yr sawlog price trends for the 10 commercial hardwood tree species in Ohio. Data were compiled from the Ohio Timber Price Report for four log grades (Prime, #1, #2, Blocking) covering the years 1960–2011, and average annual percentage rates of change in both nominal and real sawlog prices were determined. We further compared real log grade price movements within each species....
