abstract comparison of food prices in different periods, indicates fluctuations and continually upward trend. any change in agricultural sector variables, as main food supplier, will affect food price. productivity shocks and production gap are examples of such variables. in this paper ,hodrick prescott and kalman filters are used as generators of productivity shocks and production gap series. ...

a r t i c l e i n f o JEL classification: C23 E44 Q43 Keywords: Crude oil shocks Stock market prices Panel data Asymmetric adjustment Granger causality This paper proposes a panel threshold cointegration approach to investigate the relationship between crude oil shocks and stock markets for the OECD and non-OECD panel from January 1995 to December 2009. Nonlinear cointegration is confirmed for ...

a r t i c l e i n f o JEL classification: E52 G10 G14 Keywords: High oil price events Asymmetric impacts of monetary shocks Financing constraints This paper investigates whether a high oil price event that worsens the quality of a firm's balance sheet in turn provides an additional transmission channel to the stock market, which then affects stock returns. We examine the asymmetric impacts of m...

As the number of systems which offer annotations on digital documents increases, robust anchoring of annotations is a key challenge. It is especially important if the annotator lacks write-access to the document being annotated. For example, if someone makes an annotation on a web page today and the web page changes tomorrow, what happens to the annotation? One approach is simply to “orphan” th...

The main objective of this paper is to investigate the asymmetric effects of exchangerate on Iranian import price index using quarterly time series data over the period 1990- 2011. For this purpose, positive and negative shocks of the exchange rate have been separated from each other using dummy variables and the effects of the size of the exchange rate shocks by determining a threshold.The emp...

This study investigated the impact of decomposed oil price shocks on household consumption in Zambia from 1985-2019. A structural Vector Autoregressive Model (SVAR) was used to measure contemporaneous consumption, and complemented by Impulse Response Functions (IRFs), Granger Causality Tests Forecast Error Variance Decompositions (FEVD). The existence long-run relationships determined cointegra...

a r t i c l e i n f o JEL classification: F1 F4 Q43 N75 Keywords: Oil price shock Trade balance VAR Granger non-causality test Gregory-Hansen cointegration test This study aims to examine whether a large part of the variability of trade balances and their oil and non-oil components is associated with oil price fluctuations. The long-run causality running from oil price to overall, oil and non-o...

abstract in this research by using a synchronous equivalents system, the functions of supply and demand of any kind of meat and corn in fars province, iran are considered. the purpose of this study is to predict the functions of supply and the price of meat and corn, recognition and analysis of effective issued on supply and price of this sections, considering the effect of shocks and the cross...

productivity shocks are one of the most important factors that influence the firms ‘ decisions on he optimal consumption of production inputs. unobservable productivity shocks create selection and simultaneity problems causing biased estimates of production function by ordinary least squares. however, to estimate coefficients associated with production function by levinsohn and petrin technique...
