This paper proposes a parsimoniously time varying parameter vector autoregressive model (with exogenous variables, VARX) and studies the properties of the Lasso and adaptive Lasso as estimators of this model. The parameters of the model are assumed to follow parsimonious random walks, where...

This paper reviews the recent trends in agricultural investments (both public and private) and tries to find structural breaks in the trends over the period of 1960-2017. Comparing the growth performance of investments and farm output (GDPAg and production) in various sub-periods based on...

In the literature, although many studies are describing the structural break in the linear regression model with time-series data, studies investigating this issue with cross-sectional data are limited. In this study, the performance evaluation of some approaches used to determine the structural...
