This paper develops a new approach to testing for the existence of a linear long-run relationship, when the orders of integration of the underlying regressors are not known with certainty. The test is the standard Wald or F statistic for testing the significance of the lagged levels of the...

If additional information about the distribution of a random variable is available in the form of moment conditions, a weighted kernel density estimate re ecting the extra information can be constructed by replacing the uniform weights with the generalised empirical likelihood probabilities. It...

Qualitative business survey data are used widely to provide indicators of economic activity ahead of the publication of official data. Traditional indicators exploit only aggregate survey information, namely the proportions of respondents who report “up” and “down”. This paper examines...

This study contributes to the literature on burnout and turnover in child welfare by examining the applicability of conservation of resources theory (COR). This theory argues that a loss of resources leads to the stress underlying burnout. This article examines the loss of two resources in...

The central concern of this paper is parameter heterogeneity in models specified by a number of unconditional or conditional moment conditions and thereby the provision of a framework for the development of apposite optimal m-tests against its potential presence. We initially consider the...
