Econometrically accounting for identities and restrictions in models of interregional migration

"Interregional demographic identities and other restrictions are explicitly taken into account in a simple time-series model of interregional migration. This goal is accomplished through the imposition of adding-up constraints on the estimated coefficients of a multi-equation linear system and by testing for homogeneity and symmetry. The pitfalls of utilizing the described procedures for migration analysis and forecasting are discussed. Full implementation of the technique is shown to require far more time-series observations on interregional migration than are commonly available."     

The economic evaluation of job safety

Zusammenfassung Gesetzliche Regelungen und direkte staatliche Eingriffe im Bereich der Arbeitswelt, des Verkehrs oder der Umwelt haben in einem großen Ausmaß die Vermeidung oder Reduzierung von Krankheits- und Unfallrisken zum Ziel. Nicht selten verläuft die öffentliche Diskussion über die Beurteilung dieser Maßnahmen im außerökonomischen Raum unter (bewußtem oder unbewußtem) Verzicht auf die Offenlegung der Kosten-Nutzen-Aspekte. Doch gerade die Umweltproblematik demonstriert deutlich die Aktualität der Frage, anhand welcher Kriterien die politischen Entscheidungsträger derartige Maßnahmen bewerten sollen.In dieser Arbeit wird die Frage der Bewertung von Sicherheitsmaßnahmen aus der Sicht des Arbeitsmarktes aufgegriffen. Nach einer theoretischen Einleitung gibt sie einen Überblick über verschiedene methodische Konzepte zur Quantifizierung des Nutzens von Maßnahmen der Arbeitsplatzsicherheit. Im empirischen Teil wird auf der Basis von Arbeitsmarktdaten aus dem Mikrozensus 1981 und nach Wirtschaftszweigen gegliederten Unfallstatistiken öffentlicher Versicherungsanstalten die implizite Bewertung des Arbeitsplatzrisikos geschätzt. Hiefür wird die sogenannte Hedonic-price-Methode angewandt, d. h. die impliziten Preise von Arbeitnehmer- und Arbeitsplatzcharakteristika werden aus beobachteten Daten auf dem Arbeitsmarkt mit Hilfe von Regressionsschätzungen ermittelt.Aus den Koeffizienten der Risikovariablen kann über den Betrag Aufschluß gewonnen werden, den, den die Gesellschaft für die Bereitstellung von Sicherheitsmaßnahmen zur Verminderung des Unfallrisikos zu zahlen bereit ist. Die Ergebnisse weisen darauf hin, daß auch in Österreich, trotz der in der politischen Diskussion dominierenden Auffassung, erhöhtes Arbeitsplatzrisiko sei nicht durchmonetäre Entschädigungen abzugelten, eine implizite Beziehung zwischen Lohnhöhe und Arbeitsplatzrisiko besteht. Weiters zeigt sich, daß eine Bewertung von Sicherheitsmaßnahmen anhand des gesamtwirtschaftlichen Einkommensentgangs aufgrund des Produktionsausfalls, der durch die Nichtbereitstellung dieser Sicherheitsvorkehrungen entstünde, die gesellschaftliche Bewertung dieser Maßnahmen schwerwiegend unterschätzt.

Investigating attraction compatibility in an East Texas city

The study was undertaken in Tyler, Texas, a city of 83 000 population in which the primary tourism attraction is the Caldwell Zoo. The focus was on the compatibility of ancillary attractions to the zoo and their role in adding to the city's cumulative attraction. A sample of 1559 zoo visitors were surveyed. The results revealed that (i) there was a high degree of compatibility between the zoo and other attractions within the city; (ii) tourism spending by those travelling more than 60 miles was significantly higher than those travelling fewer than 60 miles; (iii) expenditures increased as the number of additional attractions visited increased, but started to decrease when the number of attractions totalled to five or more; and (iv) the number of additional attractions visited decreased as the distance travelled increased.

Explaining alliance success: Competences, resources, relational factors, and resource-advantage theory

Business alliances, by filling critical resource gaps, enable firms to have positional advantages that lead to superior financial performance. Some alliances, however, are more successful than others. The three prominent theoretical approaches to explaining alliance success rely on resources, competences, and relational factors. The authors theorize that the three approaches are interdependent and, using resource-advantage (R-A) theory as a framework, develop an integrative model. This model proposes that the three approaches are linked by means of relationships among (1) alliance competence, (2) complementary resources, (3) idiosyncratic resources, and (4) cooperation. A test of the model, using a sample of alliance professionals, finds support for the theory that the three approaches are, indeed, interdependent and that resources, construed in the manner of R-A theory, influence alliance success through positional advantage.     

Advancing marketing strategy in the marketing discipline and beyond: from promise,to neglect,to prominence,to fragment (to promise?)

ABSTRACT

The purpose of this article is to advance the field of strategic marketing within the marketing discipline, which will in turn, the author argues, contribute to enhancing the discipline’s impact beyond the narrow confines of its own journals. Towards this goal, certain aspects of the history of marketing strategy need to be reviewed. However, though this article draws extensively on historical sources, it is not a history of marketing strategy. Rather, this article uses historical materials and arguments concerning the four ‘Eras’ of marketing thought to advance five major claims: the area of strategic marketing (1) had significant promise when the marketing academic discipline was founded in Era I (1900–1920), (2) was neglected in Era II (1920–1950), (3) rose to prominence in Era III (1950–1980), (4) has become a ‘fragment’ in Era IV (1980–present) and (5) has prospects that are both promising and problematic in the future ‘Era V’. Finally, a tentative prognosis for strategic marketing and the marketing discipline is suggested.     

Medication,equipment, and supply costs for common interventions providing extended post-surgical analgesia following total knee arthroplasty in US hospitals

Aims: To estimate the cost to hospitals of materials (i.e. medications, equipment, and supplies) required to administer common interventions for post-surgical analgesia after total knee arthroplasty (TKA), including single-injection peripheral nerve block (sPNB), continuous peripheral nerve block (cPNB), periarticular infiltration of multi-drug cocktails, continuous epidural analgesia, intravenous patient-controlled analgesia (IV PCA), and local infiltration of bupivacaine liposome injectable suspension (BLIS).

Materials and methods: This analysis was conducted using a mixed methods approach combining published literature, publicly available data sources, and administrative data, to first identify the materials required to administer these interventions, and then estimate the cost to the hospital of those materials. Medication costs were estimated primarily using the Wholesale Acquisition Costs (WAC), the cost of reusable equipment was obtained from published sources, and costs for disposable supplies were obtained from the US Government Services Administration (GSA) database. Where uncertainty existed about the technique used when administering these interventions, costs were calculated for multiple scenarios reflecting different assumptions.

Results: The total cost of materials (i.e. medications, equipment, and supplies) required to provide post-surgical analgesia was $41.88 for sPNB with bupivacaine; $756.57 for cFNB with ropivacaine; $16.38 for periarticular infiltration with bupivacaine, morphine, methylprednisolone, and cefuroxime; $453.84 for continuous epidural analgesia with fentanyl and ropivacaine; $178.94 for IV PCA with morphine; and $319.00 for BLIS.

Limitations: This analysis did not consider the cost of healthcare providers required to administer these interventions. In addition, this analysis focused on the cost of materials and, therefore, did not consider aspects of relative efficacy or safety, or how the choice of intervention for post-surgical analgesia might impact outcomes such as length of stay, re-admissions, discharge status, adverse events, or total hospitalization costs.

Conclusions: This study provided an estimate of the costs to hospitals for materials required to administer commonly used interventions for post-surgical analgesia after TKA.     

The Military Occupation of Burma

In this article we study diverse ways and means by which the military controls and oppresses the people, Burman and other ethnic groups, in the name of achieving the Tatmadaw’s (Burmese military’s) three main national causes, ‘non-disintegration of the union, non-disintegration of national solidarity, and perpetuation of national solidarity’. We explore the ways the State uses their power to dominate civilian life and forms of resistance to this. State power is not uniformly practiced but occurs at different spatial scales of body, family, home, and village. Understanding the instrumentality of the State acts of violence through study of interrogation of political prisoners, offers ways to recognize the broader aspects of State pressure in the form of destruction of homes, villages, and means of livelihood. The private space of the body, home and the public village meant to shelter it has become the focus of Burmese State attempts to control the population.     

The effect of taxation on labour supply: the case of moonlighting

The authors provide a simple test of supply-side economics by estimating the responsiveness of moonlighting labour supply to changes in the marginal tax rate and the wage rate. While standard theory teachers that changes in taxes and wage should have opposite and equal effects on labour supply, taxes affect the entire asset position of the household. In the short run, an adjustment of hours in the second job may be the only option available to an individual in responding to a tax change. Thus, analyses based on after-tax wages may understate supply-side effects. To estimate these effects a tobit procedure is employed. The empirical results suggest a backward-bending supply curve over thet range of moonlighting hours. Data consist of a subsample of male blue-collar workers from the 1978 cross-section of the Panel study of Income Dynamics.     

The service-dominant logic and a hierarchy of operant resources: developing masterful operant resources and implications for marketing strategy

Marketing’s evolution toward a new dominant logic requires the focus of marketing to be on the intangible, dynamic, operant resources that are at the heart of competitive advantage and performance. First, building on resource-advantage theory’s notion of basic resources and higher-order resources, this article proposes a hierarchy of basic, composite, and interconnected operant resources. Second, reviewing research on business strategy and marketing strategy, several resources that correspond to the proposed hierarchy are identified and discussed. Third, the notion of developing masterful operant resources is introduced. Fourth, based on the proposed hierarchy and the notion of masterful operant resources, some exemplars of potential research avenues for marketing strategy are provided. Finally, the article concludes with the discussion of implications for marketing practitioners, researchers, and educators. In sum, this article extends and elaborates the concept of operant resources in the service-dominant logic of marketing.
