Is real per capita state personal income stationary? New nonlinear,asymmetric panel-data evidence

This paper re-examines the stochastic properties of U.S. state real per capita personal income, using new panel unit-root procedures. The new developments incorporate non-linearity, asymmetry, and cross-sectional correlation within panel-data estimation. Including nonlinearity and asymmetry finds that 43 states exhibit stationary real per capita personal income whereas including only nonlinearity produces 42 states that exhibit stationarity. Stated differently, we find that two states exhibit nonstationary real per capita personal income when considering nonlinearity, asymmetry, and cross-sectional dependence.     

COEFFICIENT CHANGE,PRICE EFFECTS,AND IMPLICIT ELASTICITIES: ESTIMATING MICROECONOMIC DETERMINANTS OVER TWO TIME PERIODS

This paper presents and estimates an input–output model in which input coefficient changes are functions of changing prices. The model produces results that mirror the characteristics of input demand functions based on the model of cost minimization subject to producing a desired level of output. It does not rely on the specification of a functional form for input coefficients, and it does not require the use of assumptions regarding the elasticity of substitution. Instead, it allows the actual price and coefficient changes that occur between periods to identify the implicit elasticities and own- and cross-price derivatives. Using this model, it is shown how accurate measures of price effects, including the full array of own and cross-elasticities of demand, can be estimated for models comprising up to 15 sectors given data for only two time periods.     

Timing Equilibria in an Urban Model with Congestion

All spatial urban models with congestion assume that the departure (arrival) time of commutes is exogenously determined and assume that travel speed at a given time and location depends upon the traffic density at that point in time and space. This paper presents a framework that encompasses such models, but allows workers to choose the time at which they leave home (arrive at work). This paper then proves that in general only one equilibrium exists for urban models with traditional congestion technology: a commuting pattern in which commuting is continuous and the rush hour never ends, which is unrepresentative of traffic patterns anywhere. This paper concludes by discussing alternative general equilibrium urban models with congestion that may have more realistic equilibria.     

Urban density and pupil attainment

We explore the association between urban density and pupil attainment using three cohorts of pupils in schooling in England. Although—as widely recognised—attainment in dense urban places is low on average, this is not because urban environments disadvantage pupils, but because the most disadvantaged pupils with low average attainments attend the most urbanised schools. To control for this, we exploit changes in urban density faced by pupils during compulsory transition from Primary to Secondary school, and measure educational progress at the end of the Secondary phase, relative to attainment at the end of Primary schooling. Our results suggest that there are small but significant benefits from education in schools in more densely urbanised settings. We detect this density advantage even amongst pupils moving relatively short distances between Primary and Secondary schools within urban areas, so we cannot attribute it to broad urbanisation effects experienced by pupils making rural–urban school moves. A more likely explanation lies in greater school choice and competition between closely co-located educational providers.     

Where hukou status matters: analyzing the linkage between supervisor perceptions of HR practices and employee work engagement

This paper highlights the interaction between intended human resource (HR) practices as perceived by supervisors and status similarity between supervisors and employees as a key source of variation in employee work engagement among 298 employees reporting to 54 supervisors at a luxury Chinese hotel. Using a multi-level, process-oriented approach to examine the relationship between intended HR practices by supervisors and engagement as perceived by employees, we show (1) that the interaction of supervisor perceptions of HR practices and supervisor–subordinate hukou (place of origin) status similarity is positively related to employee reports of Leader–member exchange (LMX), HR practices and work engagement; (2) that the interaction of supervisor perceptions of HR practices and hukou status similarity influences employee perceptions of HR practices through LMX; and (3) that the interaction of supervisor perceptions of HR practices and hukou status similarity influences work engagement through employee perceptions of LMX and HR practices. Theoretical and practical implications are discussed.     

Marrying personality and job resources and their effect on engagement via critical psychological states

This study examined the process by which individuals become engaged with their jobs by integrating seminal engagement theory. More specifically, we suggest that an individual factor (i.e. autotelic personality) and two contextual factors (i.e. feedback environment, job autonomy) interact to predict work engagement through three critical psychological states – namely availability, meaningfulness, and safety. This moderated mediation framework was tested using a cross section of the US population (n = 284); data were collected at two points in time with 3 months in between. Availability and meaningfulness mediated the relationship between autotelic personality and work engagement. Autotelic personality’s indirect effect on work engagement through meaningfulness and safety was conditional such that the nature of feedback environment’s effect depended on job autonomy level. Theory and practice implications are discussed.     

Researching cognition and technology: how we learn across the lifespan

This article addresses how we learn technology across the lifespan. After outlining findings of research into how children, adolescents, teens and adults learn technology, we address theoretical shifts from sociocultural to technocultural theories of cognition and reorientations from mediated to cyborgenic learning. The balance of the article describes effective methods for researching cognition and technology. In the process of outlining key findings from research, we emphasize the links among methods and theories employed, data produced and conclusions drawn. Our goal is to sketch a lifelong learning context for undertaking studies of cognition and technology, and to provide a methodological and theoretical analysis for researchers venturing into this dynamic and volatile field. In summary, we provide a far-ranging agenda for researching cognition and technology.

The Scope and Limits of a Public–Private Hybrid: Dispute Settlement under NAFTA Chapter 19

Globalisation is often depicted as having led to an increase in private authority at the expense of that of the state. It is important to correctly specify the scope that private authority has achieved and the capacity of states to push back and limit that authority. This article grounds these theoretical issues in a discussion of the hybrid, public–private dispute settlement mechanism set up in the original Canada–US Free Trade Agreement (CUSTFA), and later extended into Chapter 19 of the North American Free Trade Agreement (NAFTA). It finds that privatising the enforcement process did make a difference. Trade experts on panels saw things differently to judges and in ways that were more sympathetic to exporters. This favoured Canadian and Mexican interests. However, the arrangement lacked deep roots. It was a late-stage compromise in trade negotiations. This rendered it vulnerable to a US counterattack once panels began to rule in favour of Canadian and Mexican challenges to US trade determinations. The transfer of quasi-judicial authority to a public–private hybrid proved contingent, partly on the hegemonic state's ongoing level of comfort with the arrangement, as well as on a lack of business consensus within the United States.     

TO ADMIT OR NOT TO ADMIT: THE QUESTION OF RESEARCH PARK SIZE

A theoretical model is used to explore the determinants of the optimum size of a private research park and the effect of university affiliation on that optimum size. Parks are assumed to operate as cooperatives where costs are equally shared among the member firms, and optimality occurs when the firms’ average net benefits are maximized. To achieve this, existing members of a park will limit the park's size, denying entry to firms who wish to join and are willing to share the costs. University affiliation may either increase or decrease the optimum size of a park.
