There is a growing literature in nonparametric econometrics in the recent two decades. Given the space limitation, it is impossible to survey all the important recent developments in nonparametric econometrics. Therefore, we choose to limit our focus on the following areas. In Section 2, we review the recent developments of nonparametric estimation and testing of regression functions with mixed discrete and continuous covariates. We discuss nonparametric estimation and testing of econometric models for nonstationary data in Section 3. Section 4 is devoted to surveying the literature of nonparametric instrumental variable (IV) models. We review nonparametric estimation of quantile regression models in Section 5. In Sections 2–5, we also point out some open research problems, which might be useful for graduate students to review the important research papers in this field and to search for their own research interests, particularly dissertation topics for doctoral students. Finally, in Section 6 we highlight some important research areas that are not covered in this paper due to space limitation. We plan to write a separate survey paper to discuss some of the omitted topics.

It will be recalled that the last monograph treated the significance of the collective agreement in society. If solely a function in society, (though having a legal basis), were to be attributed to the collective agreement, this would mean that no rights or obligations whatsoever would be created between the parties to it. This is not so in practice. It is of course a fact that no legally enforceable rights and obligations normally accrue, and as already indicated, those are moral ones and are only enforceable in honour, i.e. a gentleman's agreement. Nevertheless, this does not necessarily mean that the collective agreement has no juridical significance. Even agreements which are binding in honour only, as for example the kind of agreement found in Balfour v. Balfour, have a known juridical nature. Furthermore, though the collective agreement is only binding in honour, its incorporation into the individual contract of employment makes its terms legally enforceable even though recourse to the courts is seldom had. As a source of rights and obligations of considerable importance the collective agreement must therefore have some juridical significance and cannot remain entirely in the realms of society.

The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

The most obvious symptom of the most obvious trend in the building of new libraries is the fact that, as yet, no spade has entered the ground of the site on Euston Road, London, upon which the new building for the British Library Reference Division has to be erected. Some twenty years of continued negotiation and discussion finally resulted in the choice of this site. The UK and much more of the world awaits with anticipation what could and should be the major building library of the twentieth century. The planning and design of a library building, however large or small, is, relatively speaking, a major operation, and deserves time, care and patience if the best results are to be produced.

On a global scale, leadership takes place within a complex environment that is molded both by national culture and organizational culture influences. This chapter explores leader-culture (L-C) fit in this global context. Drawing together distinct perspectives on national culture and organizational culture, we identify potential contingencies of L-C fit across these levels. In addition to identifying key gaps and areas for future exploration, we also discuss the practical uses of fit when selecting and developing leaders. Overall, we argue that researchers and practitioners could benefit from an expanded perspective on cultural fit to simultaneously address aspects of national and organizational culture.
