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. ...

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...

Understanding the dynamics of productivity shocks is instrumental if we are to identify the sources of economic growth. This paper, investigates dynamic effects of positives productivity shocks to agricultural subsectors during the period from 1991-2015, by disaggregating agricultural sector in Iran into four key subsectors (crops, livestock, fishing and forestry) through an estimated DSGE mode...

the real business cycle theory was applied to investigate the hypothesis of cyclical agreeable treatment of real wages, for men and women work force, in the iranian agricultural sector for the period of 1971-2006. on the basis of this theory, the impacts of supply side shocks (productivity and oil income shocks), are anticipated on the fluctuations of the real wages. the dominant effect of supp...

The most straightforward way to analyze investment-sector productivity developments is to construct a two-sector model with a sector-specific productivity shock. An often used modeling shortcut accounts for such developments using a one-sector model with shocks to the efficiency of investment in a capital accumulation equation. This shortcut is theoretically justified when some stringent condit...

This paper presents a real business cycle model with search frictions in the asset market, where equity liquidity is endogenously determined. I use the model to study how labor input, asset liquidity and asset prices fluctuate in response to productivity and liquidity shocks, and how, in turn, these fluctuations magnify the impact of productivity shocks on economic activity. A household’s inves...

Many explanations of the stylized facts concerning real exchange rate movements focus on monetary shocks, but it is often found empirically that monetary shocks are unimportant. I provide evidence that is contrary to this empirical finding. Using over 100 years of data, I estimate the contribution of various shocks to explaining variation in the real pound-dollar exchange rate. Monetary shocks ...

Economic theories show that the direction and magnitude of the fluctuations of economic variables depend on the type and magnitude of the shocks they are faced with. Various reasons are noted for fluctuations in demands for imports, including productivity shocks. Accordingly, this research was aimed at identifying the effects of Total Factor Productivity (TFP) shocks of the agricultural sector ...
