Wage Effects of Unemployment Duration and Frequency

This paper analyzes the wage effects of unemployment duration and frequency for different regional labor market situations in The Netherlands using a simultaneous equations approach. The main finding is that unemployment duration has a significant negative effect and the frequency of unemployment a significant positive effect on wages in the core regions with relatively low unemployment rates. In the periphery with relatively high unemployment rates no significant effects of unemployment duration and frequency are found. It is argued that in the core regions unemployment duration is primarily viewed as a personal indicator of low productivity whereas in the periphery it is attributed to the situation in the regional labor market.     

Worker Endowments and the Effects of Institutions on Earnings Realization: A Cross-National Comparison

In this study we investigate how differential institutions, and their observance within regional labor markets, impact potential earnings realization. We investigate institutional linkages to labor market outcomes by means of cross-nation comparisons between the United States and the Netherlands. In this regard, better job-matching (information) programs, higher relative unemployment benefits and minimum wages, and a greater prevalence of both trade unionism and collective bargaining likely work to the favor of Dutch workers, and in turnaugment their reservation wages during job search. The predictable outcome of higher earnings realization among Dutch workers is tested econometrically by frontier estimation.     

Estimating the Marginal Willingness to Pay for Commuting

With informational frictions on the labor market, hedonic wage regressions provide biased estimates of the willingness to pay for job attributes. We show that a recent theoretical result, which states that the variation in job durations provides a basis for obtaining good estimates, can be generalized to a wide class of search models. We apply this result by estimating the marginal willingness of employed workers to pay for commuting, using Dutch longitudinal data. The average willingness to pay for one hour commuting is estimated to equal almost half of the hourly wage rate.     

Estimating weaning and early childhood diet from serial micro-samples of dentin collagen

Age of weaning is an important measure of parental investment, and in various human and non-human primate studies, has been correlated with a range of developmental factors such as stature, cognitive functions, obesity, ability to cope with stress, and rates of disease. Archaeological estimation of the weaning process is generally at the level of an entire burial population, creating some challenges in using such data to test anthropological theory. We describe a method that tracks the weaning process at the individual level, based on the measurement of stable nitrogen and carbon isotope ratios in serial sections of first molar dentin collagen. We apply this micro-sampling technique to a sample of individuals from CA-CCO-548, a well-studied and ancient site on the banks of Marsh Creek in Central California. Results show great variation between individuals in both the length of the weaning process, the age at which breastfeeding stopped, and the source of early complementary childhood foods.     

From Peru to Ichaboe: The dynamics of a shifting guano frontier, 1840–5

The guano frontier originated as a geographic space for a socio-cultural resource central to the identity, lifestyle and worldview of the indigenous Peruvians. Colonisation in combination with advances in understandings of plant nutrition and fertiliser science, however, shifted guano’s meaning from its original roots and turned it into a globally tradable commodity. The geographical frontier, under the influence of post-independence politics and nationalisation, firstly became an economic frontier and, secondly, a political boundary. With discoveries on Ichaboe and other neighbouring islands on the southwest coast of Africa, this frontier shifted and a race for monopoly control ensued. The dynamics of the struggle for monopoly control over the guano frontier on the Namib coast challenges some of our fundamental historiographic tenets of frontiers, their very natures, triggers and movements. This article suggests the extension of a socio-ecological model in which resource demand and depletion, coupled with changes in the extension of knowledge and legal boundaries, all played roles.     

The ‘Liverpool model(s)’: cultural planning,Liverpool and Capital of Culture 2008

Within the UK, the ‘Liverpool model’ is being celebrated as the new template for Capital of Culture festivals, and culture led urban regeneration in general. This paper will question this celebration and argue that there are, in fact, two ‘Liverpool models’: the first, outlined in its bid and developed within its initial planning strategy, represented the apogee of a New Labour informed ‘cultural planning’ framework for urban development; the second, developed post-2008 within the impact analysis Impacts08, is a more sober and realistic reflection of the role of culture in urban regeneration. This paper will demonstrate how this first model, while politically expedient and rhetorically seductive, was both theoretically unstable and practically unrealizable. Its subsequent abandonment represents an indictment of cultural planning as a nostrum for the complex structural, social and economic problems of the post-industrial city.
