Nowadays, it is easy to find radio transceivers having small size, low cost and still offering numerous functionalities. High-integration of radio-frequency (RF) circuits is still the main trend in the development of wireless devices. A down-converter is an essential part of any RF receiver. It basically performs the frequency translation between an incoming RF signal into a lower frequency to ...

We propose a general framework for analyzing structural limited dependent variable models where an endogenous regressor is also limited in range. A copula-based modeling of structural joint distributions permits us to implement a full information maximum likelihood estimation of parameters. We apply this modeling strategy to the March 1992 and 2002 CPS data for estimating the average partial ef...

This paper provides an empirical analysis of the association between corruption perception and the willingness to offer bribes, as well as of the influence of different sources of information on corruption perception in the Ukraine. The higher the perceived corruption in an organization, the more probable it is that a person dealing with that organization will offer a bribe, therefore supportin...

This paper considers the evaluation of the average treatment effect of a binary endogenous regressor on a binary outcome when one imposes a threshold crossing model on both the endogenous regressor and the outcome variable but without imposing parametric functional form or distributional assumptions. Without parametric restrictions, the average effect of the binary endogenous variable is not ge...

A nonlinear model is proposed in light of the theory isodamage curves, to assess cumulative fatigue damage under multistage loading. The curves were developed through S-N envelope, by Pavlou. adopted functional form a commonly accepted general form. In present work, stress function for life exponent derived with aid curve only. model, no adjusting parameters are necessary estimation. prediction...

In this paper, we discuss the derivation and application of a bivariate ordered probit model with mixed effects. Our approach allows one to estimate the distribution of the effect (gamma) of an endogenous ordered variable on an ordered explanatory variable. By allowing gamma to vary over the population, our estimator offers a more flexible parametric setting to recover the causal effect of an e...

I use data from the South African Social Giving Survey to investigate the role of social capital and motivations for giving to formal charities and beggars. Results suggest that both impure altruism and inequality aversion positively influence giving to formal charities but they have no influence on giving to beggars. The role of social capital is varied. Members of informal insurance groups ar...

The Truckee / Carson / Walker River Watershed in Northern Nevada is under an imminent threat of infestation by the New Zealand Mud Snail, an aquatic nuisance species with the potential to harm recreational fisheries. We combine a utility-theoretic system-demand model of recreational angling with a Bayesian econometric framework to provide estimates of trip and welfare losses under different typ...
