A Digital Elevation Model (DEM) of 20m spatial resolution was used to derive terrain parameters. The presence and absence of P. incana in relation to slope gradient and aspect were determined.  ...  The Topographic Wetness Index (WI), a component of the TOPMODEL was derived from the DEM and its relationship with the spatial distribution of P. incana was explored.  ...  It is suited to models where the dependent variable is dichotomous and hence discrete (0, 1).  ...

We make our argu- ment in the context of a dual economy model in which wage rates need not be equalized across sectors.  ...  Financial repression, in the form of low urban interest rates and an overvalued exchange rate, is one element in producing a dual labor market. !” The intuition is quite simple.  ...
