Measures of non-exchangeability for bivariate random vectors

We introduce a set of axioms for measures of non-exchangeability for bivariate vectors of continuous and identically distributed random variables and give some examples together with possible applications in statistical models based on the copula function.     

Work-related upper extremity injuries: prevalence,cost and risk factors in military and civilian populations

Persons with musculoskeletal-related disorders represent a prevalent source of outpatient visits, lost work time and disability in the military; however, research concerning the extent of work-related upper extremity disorders (WRUEDs) within this population is lacking. This literature review examined studies in civilian and military settings to ascertain the prevalence, cost and risk factors associated with WRUEDs. The results indicated that the prevalence and cost of WRUEDs in the civilian workforce are significant, justifying the need to research the military population. The literature also outlined physical, individual and psychosocial factors associated with WRUEDs that will help identify potential risk factors within military occupations.     

Infinitesimal sensitivity of posterior distributions

We measure the local sensitivity of a posterior expectation with respect to the prior by computing the norm of the Fréchet derivative of the posterior with respect to the prior over several different classes of measures. We compute the derivative of the posterior upper expectation when the prior varies in a restricted ?-contamination class. A bound on the global sensitivity of a class of priors is obtained. As an application, we show that of all sets with posterior probability 1 — α, the likelihood region minimizes the norm of the Fréchet derivative over the ?-contamination class and so is, in some sense, the most robust region with this posterior probability. But there exist counterexamples to this result for other classes of priors.     

Shaping the digital transformation of the retail banking industry. Empirical evidence from Italy

Although numerous studies have investigated the determinants of users’ acceptance of online channels, little attention has been paid to the continuous usage of a direct bank. To address this research gap, we analysed data collected via semi-structured interviews and a survey questionnaire distributed in 2017 to a sample of Italian bank customers. Responses were evaluated using a different statistical methodology based on the Shapley Value regression analysis. In brief, user-friendliness and economic advantages appear to be more decisive at an early stage of adoption. Moreover, structural assurance mechanisms (e.g. clarifying security policies and guarantees) have a robust impact on keeping customers online and loyal to electronic channels. Surprisingly, accessibility and compatibility do not seem to be determinant factors.     

The Endogenous Construction of Accounting Discourses in a Trade Union

The exploration of accounting practices reported in this paper illustrates how perceptions of financial problems and notions of economic accountability develop within cultural and institutional environments that substantially differ from those of the business firm. The paper seeks to oppose a notion of economic determinism which, explicitly or implicitly, promotes the ideal identity between market and society. In contrast to such a view, an institutional and organizational embedded understanding of accounting is suggested as a more fruitful way of appreciating the nature and scope of economic discourses as they develop within a nonprofit organization. The analysis focuses on the ways in which economic functioning is interpreted and accountability developed within an organization that rejects stereotyped views of managerialism and conventional notions of economic rationality. The presence of endogenous fabrications of economic accounts is what eventually allows us to problematize the way in which the economic framework is all too easily seen to enter non-business environments as a colonizing force.     

The individual side of ambidexterity: Do individuals’ perceptions match actual behaviors in reconciling the exploration and exploitation trade-off?

The paper addresses the issue of the exploration–exploitation dilemma, adopting a micro level of analysis. Unlike the extensive literature on ambidexterity that investigates the organizational solutions that allow firms to pursue the balance between the two kinds of learning orientation, this research draws attention to the as yet barely analyzed individual dimension of ambidexterity. Specifically, in investigating personal ambidexterity we point to the relevance of individuals’ perceptions on what their role requires of them and the actual behaviors they perform.

Money and Credit Redux

We analyze money and credit as competing payment instruments in decentralized exchange. In natural environments, we show the economy does not need both: if credit is easy, money is irrelevant; if credit is tight, money is essential, but credit becomes irrelevant. Changes in credit conditions are neutral because real balances respond endogenously to keep total liquidity constant. This is true for both exogenous and endogenous debt limits and policy limits, secured and unsecured lending, and general pricing mechanisms. While we show how to overturn some of these results, the benchmark model suggests credit might matter less than people think.     

Dynamics of Female Employment and Youth Unemployment in Italy

ABSTRACT: The authors, in this article, consider the possibility of how the peak in the birth rate during the 60s could have affected the present unemployment situation. First of all the hypothesis put forward by various sources that the baby boom is the principle cause of unemployment is examined, together with how plausible this explanation is. Then some data relevant to birth rates and the subsequent employment levels in various countries is presented, and finally, a more detailed analysis of the Italian situation is given, both with regard to the baby boom and the most recent employment statistics for the different Italian areas. The authors also take a close look at the female labour market and its development over the past years, and how these figures would appear to confute the baby boom as being the sole cause responsible for present day unemployment levels.
