tall wheatgrass (agropyronelongatum) is native to iran and is used in a wide area of rangelands and also used in drylandseeding program. this plant produces green and dry fodder and has a great importance in protecting drylands from water and wind erosion.seed proteome analysis was conducted under three conditions, namley, optimum (20 °c and zero water potential), drought conditions (20 °c and ...

This paper sums up the applications of statistic models such as ARCH-family models, cointegration theory and Granger causality etc in oil price time series analysis and introduces the method of data mining combined with statistic knowledge to analysis oil price time series. In addition, the paper also explains advantages, functions, relevant technologies of this method and its potential applica...

Experts have better information about the appropriate quality of treatment or surplus from trade than their customers. Providing both diagnosis and treatment, this leaves scope for fraud. In a credence good set-up, we experimentally investigate how intensity of price competition and the level of customer information about past expert behavior in uence an expert's incentive to defraud his custom...

Recent research highlights the importance of biased expectations and inattention for nonlinear pricing in dynamic environments. Findings are: (1) Three-part tariffs, such as cellular service contracts, exploit consumer overconfidence. (2) Surprise penalty fees may be used to further exploit biased beliefs or alternatively to price discriminate more efficiently whenever consumers are inattentive...

Heat-Shock Factor 1 (HSF1), master regulator of the heat-shock response, facilitates malignant transformation, cancer cell survival, and proliferation in model systems. The common assumption is that these effects are mediated through regulation of heat-shock protein (HSP) expression. However, the transcriptional network that HSF1 coordinates directly in malignancy and its relationship to the he...

This paper applies an integrated CGE-microsimulation model to analyse the impact of the 2006-08 increase in commodity prices on Uganda. Previous impact analysis studies suggested that the food price shock increased poverty in Uganda as there are more net food buyer than net food seller households. We show that the agriculture commodity price shocks were povertyreducing, but the simultaneous inc...

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 inflation, and as a result, their investment is more sensitive to nominal price shocks. We also find that the overall degree of nominal indexation inc...

This paper analyses the implications of cost-push shocks for the optimal choice of monetary policy target in an two-country sticky-price model. In addition to cost-push shocks, each country is subject to labour-supply and money-demand shocks. It is shown that the fully optimal coordinated policy can be supported by independent national monetary authorities following a policy of flexible inflati...

We investigate how firms’ cross learning amplifies industry-wide investment waves. Firms’ technologies are subject to idiosyncratic shocks and a common shock, and their asset prices aggregate speculators’ private information about the two types of shocks. In investing, each firm learns from other firms’ prices (in addition to its own) to make better inference about the common shock, leading to ...

Abstract We give a full analytic characterization of large class sticky-price models where the firm’s price-setting behavior is described by generalized hazard function. Such function allows for vast variety empirical hazards to be fitted. This setup microfounded random adjustment costs, as in Caballero and Engel (1999), or information frictions, Woodford (2009). establish two main results. Fir...
