the output error of the globoidal cam mechanism can be considered as a relevant indicator ofmechanism performance, because it determines kinematic and dynamical behavior of mechanicaltransmission. based on the differential geometry and the rigid body transformations, themathematical model of surface geometry of the globoidal cam is established. then we present theanalytical expression of the ou...

the iranian poultry sector has experienced many significant structural changes in recent years. such changes may have influenced price dynamics and transmission of shocks through marketing channels especially on retail markets. this paper investigate price transmission, threshold behavior and asymmetric adjustment in poultry sector of ardebil (ar), east azerbaijan (ea) and west azerbaijan (wa) ...

over the past three decades vertical price transmission analysis has been the subject of considerable attention in applied agricultural conomics. it has been argued that the existence of asymmetric price transmission generates rents for marketing and processing agents. retail prices allegedly move faster upwards than downwards in response to farm level pricemovements. this is an important issue...

in this paper asymmetric price transmission mechanism and nonlinear adjustment between producer and retail prices of milk were examined in zanjan province of iran. for this purpose, a two-regime threshold vector error correction model (tvecm) and a sup-lm test developed by hansen and seo (2002) were employed for checking presence of a threshold effect. application of unit root tests indicated t...
