Labor productivity convergence in the Kansas farm sector: a three-stage procedure using data envelopment analysis and semiparametric regression analysis

This paper employs a three stage procedure to investigate labor productivity growth and convergence in the Kansas farm sector for a balanced panel of 564 farms for the period 1993?C2007. In the first stage, Data Envelopment Analysis is used to compute technical efficiency indices. In the second stage, labor productivity growth is decomposed into components attributable to efficiency change, technical change, and factor intensity. The third stage employs both parametric and semiparametric regression analyses to investigate convergence in labor productivity growth and the contribution of each of the three components to the convergence process. Factor intensity and efficiency change are found to be sources of labor productivity convergence while technical change is found to be a source of divergence. Policies that encourage investment in capital goods may help to mitigate disparities in labor productivity across the farm sector.     

Culture, infrastructure and international health benefits delivery

When selecting a health insurance carrier for international employees, it is advantageous to recognize that valid assumptions made when selecting domestic benefits simply do not apply in the international realm and can lead to costly errors. This article examines some scenarios and cultural anomalies that invalidate commonly accepted domestic health insurance practices. It explores strategies for simplifying benefit design, providing access to quality care abroad, assessing costs, minimizing overseas risks and understanding the cultural impact on health care delivery.     

HETEROGENEITY,FRICTIONAL ASSIGNMENT,AND HOME-OWNERSHIP

We study the composition of the housing stock across ownership and rental markets in a dynamic model of frictional assignment. Houses are rented or sold to heterogeneous households that sort over quality. Due to matching frictions and an increasing ownership surplus, wealthy households tend to own and lower value housing tends to be rented, even without financial frictions or rental supply constraints. When calibrated to match key housing market features of the average U.S. city, the model is consistent with observed empirical relationships across cities. We study the model's implications for affordability, ownership, and the impact of progressive property taxation.     

Experimental errors in predictions of thermal hazards

Predictions of critical conditions for thermal runaways are generally based on heat balance models using experimentally generated heat and kinetic data. The accuracy of the predictions depends on the fit of the models and the quality of the thermal data. The relative importance of these factors to the calculated critical reaction conditions are discussed. Some additional procedures for evaluating and improving results are recommended.     

Engineering the revolution? Imagining the role of new digital technologies in infrastructure work futures

Contemporary imaginations of the impact of new digital technologies (NDTS) are dominated by utopian visions of a ‘revolution’ in productivity and efficiency, contrasted with dystopian views of declines of work and human skills, and distrust of artificial intelligence's efficacy. This article explores imaginations of digital futures in the infrastructure sector through case study research of a global engineering organisation. Drawing on a practice approach, a typology is generated from interviews with engineers and managers to reveal that three broad imaginations compete within the organisation: technodeterminism; technoscepticism; and human-centric, all with utopian and dystopian variants. Clear relationships exist between the diverse imaginary positions taken by employees with their different roles, biographies and levels of the organisational agency. Those with relatively higher levels of agency tended towards technocentric utopianism while those with lower levels of agency displayed a resolutely dystopian version. Conversely, while the outward-facing image of the organisation promotes a utopian imagination of a technologically driven future, those with the very highest levels of the organisational agency remain technosceptic. This means that real change is slow. However, an encouraging manifesto for the future is suggested by those who are innovating NDTS to reimagine alternative infrastructure futures through improved human-centric social outcomes.
