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...

This paper investigates the presence of threshold effect public debt and internal on economic growth in Kenya for period 1970-2018. The Smooth Transition Regression model analysis is used to analyze growth. findings study indicate that level 17.3115% implying domestic positively impacts when this exceeded. estimate 33.29% affected exceeds level. results imply have a U-shaped relationship with r...

We study critical threshold phenomena in a dynamic continuum traffic flow model known as the Payne and Whitham (PW) model. This model is a quasi-linear hyperbolic relaxation system, and when equilibrium velocity is specifically associated with pressure, the equilibrium characteristic speed resonates with one characteristic speed of the full relaxation system. For a scenario of physical interest...

In many applications, the response variable is observed only when it is above or below a given threshold otherwise the threshold itself is observed. Tobit median regression model is a useful semiparametric procedure for analyzing this type of censored data. We propose a simple nonparametric test for assessing the common linearity assumption in this model. Compared to those existing methods in t...
