This paper proposes a new conditional mean test to assess the validity of binary and fractional parametric regression models. The new test checks the joint significance of two simple functions of the fitted index and is based on a very flexible parametric generalization of the postulated model....

Efficiency has long been an issue of concern in the electricity sector. Most existing studies relate technical efficiency in the electricity sector to policy or environmental factors. The impact of firm operation factors has rarely been discussed. We estimate Stochastic Frontier models using...

Confidence in general and consumer confidence in particular are subject to increasing interest by many agents, including central banks and governments at the national level, and supranational entities, such as the European Commission of the European Union. Although the academic community shares...

Binary response index models may be affected by several forms of misspecification, which range from pure functional form problems (e.g. incorrect specification of the link function, neglected heterogeneity, heteroskedasticity) to various types of sampling issues (e.g. covariate measurement...
