Housing-choice hindrances and urban spatial structure: Evidence from matched location and location-preference data in Chinese cities

In a monocentric city with a well-functioning residential market, Pareto-efficient spatial equilibrium entails the sorting of residents according to their bid–rent gradient in descending order away from city center. Violation of this sorting condition creates opportunities for Pareto-improving trading of locations and can be sustained only if the market is hindered. We propose a simple ordered-location-choice model using matched location and location-preference data of individual households to examine violations of the Pareto-efficient spatial sorting condition. In so doing we are able to identify population groups facing housing-choice hindrances. We find in a sample of Chinese cities undergoing housing market liberalization that poor marketability of the previously state-provided homes, inadequate provision of housing finance, and spatial mismatch between job-market and housing-market opportunities contribute to a Pareto-inefficient spatial structure.     

Depletion or expansion? Understanding the effects of support policy use on employee work and family outcomes

Past research on the effects of employees' use of work–family support policies tends to draw on a depletion perspective suggesting that using these policies may reduce work–family conflict. The emphasis on depletion fails to consider the expansion perspective that assumes that using work resources may enrich family functioning. Using a sample of 113 matched employee–supervisor pairs and a 1‐month separation between predictor and criterion measurement, we found support for the expansion rather than the depletion perspective. Specifically, the relationships between support policy use and employee job satisfaction and family efficacy (but not organisational citizenship behaviour) were mediated by work‐to‐family enrichment; these effects were realised only for employees with high levels of family identity. In contrast, no support was found for family‐to‐work conflict as a mediator of the model.     

Roles, resources and benefits of intermediate organizations supporting triple helix collaborative R&D: The case of Precarn

Triple helix collaborations involving academia, government and industry are believed vital to the success of regional technology development. However, due to differences in culture, organizational functioning and incentive mechanisms as well as the different objectives of the various actors involved, such collaboration is difficult to create and sustain. A case study of the organization called Precarn, a collaborative, which manages a program of triple helix projects, is used here to illustrate how an intermediate organization can help triple helix partnerships towards the successful commercialization of new technologies. The paper contributes to the literature on managing R&D collaborations and innovation networks using organization theories to explain why and how collaborative intermediate organizations can facilitate successful technological adoption and commercialization across innovation networks.     

Simplified Alonso–Mills–Muth model with a monopoly vendor

One important but unrealistic assumption in the simplified Alonso–Mills–Muth (AMM(0)) model is that the composite good is ubiquitous and thus there is zero shopping cost for residents. This paper assumes that the composite good is only sold by a monopoly vendor inside the city and hence a shopping cost is inevitable for residents. It is shown that the vendor will locate at the city boundary in equilibrium. In contrast to the symmetric land rent pattern in the AMM(0) model, the current AMM(k) model offers an asymmetric land rent pattern in equilibrium. Moreover, this paper shows that a rent-maximizing government either regulates the vendor to locate at the central business district (CBD) (when income is high) or does not enact any regulation (when income is low).     

Relationship between the Mean and the Constant in a Box–Jenkins Time Series Model

In some publications the mean is identified with the constant of a Box–Jenkins time series model. In this paper the relation between both terms is demonstrated. Furthermore, by means of an example, the errors which may be made if one does not use each term adequately are shown.     

The business cycle in the G-7 economies

In this paper the Hodrick–Prescott filter is used to decompose real GDP for the G7 countries into cyclical and trend components. The resulting series of cyclical components are then examined for static relationships, using correlations and graphs; long-run relationships using autoregressive-distributed lag models; and short-run relationships, using error–correction models. The main result is that the patterns of cyclical behaviour changed following the oil price shocks in the 1970s. Since 1980, cyclical fluctuations have been smaller as a result of a decline in synchronisation of the cycles in the G7. Two separate cycles seem to be developing since 1990. One is for Germany, Italy and France, whilst the other is for the US, UK and Canada. Within each of these groups there are both long-run and short-run relationships between the cyclical components of GDP.     

Who is fit to serve? Person–job/organization fit,emotional labor,and customer service performance

This study investigates person–job (P–J) fit and person–organization (P–O) fit perceptions and relates these perceptions to employees' emotional labor and customer service performance. Data from a two‐point, time‐lagged study of 263 employees and 690 customers reveal that both P–J and P–O fit relate positively to deep acting and negatively to surface acting, in accordance with an emotional labor perspective. In addition, P–J and P–O fit are jointly associated with emotional labor, such that the positive link between P–J fit and deep acting is stronger, and the negative link between P–J fit and surface acting is weaker when P–O fit is high. Emotional labor partially mediates the interactive effects of P–J and P–O fit on service interaction quality and customer satisfaction; service interaction quality relates positively to customer satisfaction. These findings have multiple theoretical and practical implications.     

On the interpretation of cointegration in the linear–quadratic inventory model

The traditional formulation of the linear–quadratic inventory model with unit roots predicts cointegration between inventories and sales. That formulation implies that marginal production costs and the marginal benefits of inventories are both tending to ∞, and the cointegrating coefficient reflects the optimal trade-off between these competing factors. This paper suggests a reformulation of the problem in which marginal production costs and marginal inventory benefits are both stationary and in which the cointegrating coefficient is the same as the value that characterizes the target inventory level in the cost function.
