Recent empirical work in several economic fields, particularly environmental and energy economics, has adapted the regression discontinuity (RD) framework to applications where time is the running variable and treatment begins at a particular threshold in time. In this guide for practitioners,...

There has been continuing interest in Bayesian regressions without imposing any parametric assumption on the error distribution, but the asymptotic efficiency of such procedures has not been fully understood yet. In this article, we consider semiparametric Bayesian nonlinear regression models....

The literature on numerical methods for fitting nonlinear regression model has grown enormously in the fast five decades. An important phase in nonlinear regression problems is the exploration of the relation between the independent and dependent variables. A largely unexplored area of research...

Partial derivatives have a special place in economics since the marginal revolution of the 1850s. We present results from multivariate partial derivative estimates using nonlinear non-parametric regressions in a finite difference method, accessible via the R-package NNS. Numerical partial...

This paper considers the problem of model averaging for regression models that can be nonlinear in their parameters and variables. We consider a nonlinear model averaging (NMA) framework and propose a weight-choosing criterion, the nonlinear information criterion (NIC). We show that up to a...

This paper develops an asymptotic theory for nonlinear cointegrating power function regression. The framework extends …. Accompanying the asymptotic theory of nonlinear regression, the paper establishes some new results on weak convergence to … stochastic integrals that go beyond the usual semi-martingale structure and considerably extend existing limit theory …

We consider nonparametric estimation of the regression function g(*) in a nonlinear regression model Y<sub>t</sub> = g(X<sub>t</sub>) o(X<sub>t</sub>)e<sub>t</sub>, where the regressor X<sub>t</sub> is a nonstationary unit root process and the error e<sub>t</sub> is s sequence of independent and identically distributed (i.i.d.) random variables. With proper...
