Empirical evidence shows that entrepreneurs hold a large fraction of wealth, have higher saving rates than workers, and face substantial uninsurable entrepreneurial and investment risks. This paper constructs a heterogeneous-agent general equilibrium model with uninsurable entrepreneurial risk and capital-market imperfections to explore the implications of uninsurable entrepreneurial risk for w...

Let (X ,μ) be a probability space, set X to be distributed according to μ and put Y to be an unknown target random variable. In the usual setup in learning theory, one observes N independent couples (Xi, Yi)Ni=1 in X × R, distributed according to the joint distribution of X and Y . The goal is to construct a real-valued function f which is a good guess/prediction of Y . A standard way of measur...

Shear wave velocity is a basic engineering tool required to define dynamic properties of soils. In many instances it may be preferable to determine Vs indirectly by common in-situ tests, such as the Standard Penetration Test. Many empirical correlations based on the Standard Penetration Test are broadly classified as regression techniques. However, no rigorous procedure has been published for c...

Poverty is the most serious threat to natural resources and the environment and most of the poor are rural-based who engage in various agricultural activities. Land is a critical asset for the rural poor and lacking means to appropriately intensify agriculture which compels the poor to either overuse or misuse this natural resource base to meet basic needs. This study presents empirical relatio...

In Nigeria, most farming activities rely on family labor. However, rural-urban drift and the movement of young people away from agriculture are making labor increasingly pause. Thus, labor has become a major constraint to expanding the scope of production by small-scale resource poor farmers. This paper provides an empirical relationship between labor and poverty using data from households. Thr...

Quite often shadow economy (SE) and corruption are seen as "twins", which need each other or fight against each other and theoretically can be either complements or substitutes. Therefore, the relationship between SE and corruption has been a controversial and polemical issue and in the spotlight of a remarkable collection of economists and social researchers. The main objective of this study ...
