background: despite demonstration of molecular and biochemical changes induced by heat shock on leishmania , the immunological importance of such changes has not been elucidated. objective: studying the effect of two excretory factors prepared under heat shock and ambient temperature from leishmania major on balb/c splenocytes function. methods: the parasites were cultured at 25 ° c and the...
We examine the price dynamics in Indian cities using cointegration analysis. We identify and then calculate a common trend for prices in these 25 cities. We obtain the impulse response functions to calculate the rates of convergence to the prices, and find that the half-life of any shock is very small for Indian cities. Although a close to three-month half-life seems too fast, there are some in...
This paper examines the effect of the volatility of oil prices on food price in South Africa using monthly data covering the period 2002:01 to 2014:09. Food price is measured by the South African consumer price index for food while oil price is proxied by the Brent crude oil. The study employs the GARCH-in-mean VAR model, which allows the investigation of the effect of a negative and positive s...
In 2005 and 2006, the split-share structure reform converted the nontradable shares of most domestic public firms in China to tradable shares. This conversion imparted a drastic supply shock to the public market. Studying this unique event, we provide direct evidence to support an inelastic demand curve for stocks. Abnormal returns of the sample firms resulting from the reform are found to be n...
In many retail markets, prices rise faster than they fall. We develop a model of search with learning to explain this phenomenon of asymmetric price adjustments. By extending our static game analysis to the dynamic setting, we demonstrate that asymmetric price adjustments arise naturally. When a positive cost shock occurs, all the searchers immediately learn the true state; the search intensity...
Temperature is important for mosquito development and physiological response. Several genes of heat shock protein (HSP) families are known to be expressed in mosquitoes and may be crucial in responding to stress induced by elevated temperature. Suppression subtractive hybridization (SSH) was used to identify target transcripts to heat shock treatment in female Aedes aegypti. Subtraction was per...

The aim of this paper is to consider the effects of monetary policy on production and prices through asset price channel (the housing price index) in Iran during 1368Q1 to 1387Q4. By Vector Error Correction (VEC) Model, the effect of monetary policy has been considered through this channel. In general, the results show that the debt of banks to the central bank as instruments of monetary policy...
Sticky-price models often suggest that relative price distortion is a major cost of ination. We provide an intuition for this: Even at low rates, ination strongly a¤ects price dispersion which in turn has an impact on the economy qualitatively similar to, and of the order of magnitude of, a negative shift in productivity. The utility cost of price dispersion is quanti ed and its impact on opt...
We study a model with repeated moral hazard where financial contracts are not fully indexed to inflation because nominal prices are observed with delay as in Jovanovic & Ueda (1997). More constrained firms sign contracts that are less indexed to the nominal price and, as a result, their investment is more sensitive to nominal price shocks. We also find that the overall degree of nominal indexat...
