The Returns to Academic and Vocational Qualifications in Britain

This paper uses data from the 1991 sweep of the National Child Development Study (NCDS) and the 1998 Labour Force Survey (LFS) to provide a comprehensive analysis of the labour market returns to academic and vocational qualifications. The results show that the wage premia from academic qualifications are typically higher than from vocational qualifications. However, this gap is reduced somewhat, when we control for the amount of time taken to acquire different qualifications. This is particularly important for vocational courses, which generally take shorter time periods to complete. In the paper we also investigate how returns vary by gender, subsequent qualifications, and the natural ability of individuals. Finally, by comparing the NCDS results with those from the LFS, we estimate the bias that can result from not controlling for factors such as ability, family background and measurement error. The results reveal that the estimated returns in the NCDS equations controlling for ability, family background and measurement error are similar to the simple OLS estimates obtained with the LFS, which do not control for these factors. This suggests that the biases generally offset one another.     

Poor relief in Elizabethan English communities: an analysis of Collectors' accounts

This article analyses 30 accounts of income and expenditure left by Collectors for the Poor in Elizabethan England, before the period known as the old poor law. Collectors were appointed by parishes and incorporated boroughs in accordance with the poor laws of 1552 and 1563, but few of their fragile records survive. The accounts examined here document early use of compulsory rates to provide income, but several features of the distribution of relief differ from patterns common in the seventeenth and eighteenth centuries. Adult male recipients outnumbered women in many of the parishes; children were frequently helped directly; and cities and towns assisted a smaller fraction of their total populations than did villages but awarded larger per capita payments. Accounts from the 10 villages and small towns analysed most fully show that Elizabethan Collectors were moving away from the late medieval practice of providing only occasional aid; increasingly they awarded regular payments to a selected subset of the local poor. Comparison with the early seventeenth century suggests that the poor laws of 1598 and 1601 contributed to a transition that was already underway but did not create a new system of relief.     

Enabling the language of accessible tourism

The growing body of literature on “accessible tourism” lacks a critical scholarly debate around its specific language use and nomenclatures. To fill this gap, this paper provides a first examination of language. Language provides a unique capability to resist, strengthen and reframe identities of individuals and groups, yet can also reinforce, weaken and perpetuate dominant worldviews of disability. A content analysis examined previous accessible tourism literature with results illustrating that diversity exists amongst the varying terminologies adopted by scholars. Terms were employed loosely, inconsistently and interchangeably, euphemistically with erroneous understandings and nuances. The paper concludes with critical discussion about the power of researchers to (re) produce oppression through language that maligns and misrepresents, or to (re) conceptualise and (re) construct the world we live in with liberating language that facilitates positive social change.     

An Insight into the Personal and Emotive Context of Wildlife Viewing at the Penguin Place,Otago Peninsula,New Zealand

The personal and emotive context of visitors’ experiences has been neglected in much sustainable tourist attraction management. This paper applies ASEB demi-grid analysis as a consumer-orientated management tool to facilitate an understanding of the beneficial experiences gained by international visitors to a penguin-watching tourism attraction on the Otago Peninsula, New Zealand. Forty in-depth interviews with visitors showed that the main beneficial experiences gained included reported enhanced environmental awareness (cognition) and ‘mood’ benefits (affection). In addition, several consistent themes emerged from the beneficial experiences reported by tourists, including issues related to viewing, proximity, authenticity and wonder. Findings thus included the perceived importance of visitors to be able to view endangered penguins ‘up close’ in their natural habitat to elicit feelings of exploration and privilege, to appreciate the simplicity and naturalness of the setting and to increase their knowledge of the species through interaction with an experienced guide.     

The presence of an error term does not preclude causal inference in regression: a comment on Krause (2012)

A recent article by Krause (Qual Quant, doi:10.1007/s11135-012-9712-5, Krause (2012)) maintains that: (1) it is untenable to characterize the error term in multiple regression as simply an extraneous random influence on the outcome variable, because any amount of error implies the possibility of one or more omitted, relevant explanatory variables; and (2) the only way to guarantee the prevention of omitted variable bias and thereby justify causal interpretations of estimated coefficients is to construct fully specified models that completely eliminate the error term. The present commentary argues that such an extreme position is impractical and unnecessary, given the availability of specialized techniques for dealing with the primary statistical consequence of omitted variables, namely endogeneity, or the existence of correlations between included explanatory variables and the error term. In particular, the current article discusses the method of instrumental variable estimation, which can resolve the endogeneity problem in causal models where one or more relevant explanatory variables are excluded, thus allowing for accurate estimation of effects. An overview of recent methodological resources and software for conducting instrumental variables estimation is provided, with the aim of helping to place this crucial technique squarely in the statistical toolkit of applied researchers.     

The return from travel: a new beginning?

Within the context of the return from long-term travel, this paper uncovers the transitional and at times traumatic nature of return for 24 OE (overseas experience) travellers. Important considerations are raised in respect of easing repatriation distress among those returning from long-term travel. Contributing an understanding of the experience of return from travel, this paper proffers that return to the place one left to travel from does not necessarily mark the end of the journey. Conversely, it can mark a new beginning. As such, we argue that a broader framework for examining the travel experience is called for; notably, one that extends the examination of the travel experience to the return phase and beyond.     

Social class, family background, and intergenerational mobility

This research examines the various approaches taken by economists and sociologists for analyzing intergenerational mobility. Social mobility models based on social classes arising from an occupational classification scheme are analysed. A test for the statistical validity of classification schemes is proposed and tested using Danish sample survey data that was first collected in 1976 and augmented in 2000. This is referred to as a homogeneity test and is a likelihood ratio test of a set of linear restrictions which define social classes. For Denmark it is shown that this test fails for an Erikson-Goldthorpe classification system, raising doubts about the statistical validity of occupational classification systems in general. We also estimate regression models of occupational earnings, household earnings, and educational attainment using family background variables as covariates controlling for unobservables, measurement error, and simultaneous equation bias. In these models homogeneity tests are also rejected. We conclude from these results that the individual's family background has a small but significant impact on lifetime chances which is not captured by the Erikson-Goldthorpe classification scheme.     

Efficiency of the office properties market

This paper reports the results of an efficient markets test of the Dallas-Fort Worth office properties market. ARIMA models using a comprehensive data set did not produce superior forecasts. The results provide further evidence of the efficiency of real estate markets.
