This paper considers transformations of nonlinear semiparametric mean functions that yield moment conditions for estimation. Such transformations are said to be information equivalent if they yield the same asymptotic efficiency bound. I derive a unified theory of algebraic equivalence for...

In this paper we prove the symmetry result for solutions of nonlinear elliptic Neumann boundary value problems by using the Alexandrov's method of reflection and maximum principle, on the unit ball in the n-dimensional Euclidean space with n ≥3

This paper develops a nonlinear spatial dynamic panel data model, with one particularly interesting application to a structural interaction model for share data. To account for effects from popular units, the spatial weights matrices in our model can allow for dominant units, with unbounded...

The main objective of this paper is to assess the impact of female unemployment on economic growth in Cameroon. Using the Auto Regressive Distributed Lag (ARDL) model, applied to data covering the period 1987-2020, our results show that the relationship between female unemployment and economic...

Chronoamperometry (CA), phase space reconstruction, correlation dimension, multifractal detrended fluctuation analysis (MFDFA) combining linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), and surface morphology observation were used to systematically analyze the...
