Effects of Initial Payment Policy on the Welfare of Saskatchewan Wheat and Barley Producers

This paper calculates the historical ex ante producer surplus of initial payments acting as price floors to Saskatchewan wheat and barley producers. To do this, a Nerlovian-type partial adjustment model and rational expectations are used. The Nerlovian model is somewhat unique in that it is argued that the Nerlovian partial adjustment model can be expanded to a multi-product partial adjustment model, and this is strongly supported by the data. The calculation of the ex ante producer surplus to Saskatchewan producers indicates that initial payment policy is causing only minor market distortions.
Dans le présent document, on établit la partie excédentaire des paiements par anticipation initiaux à la production qui servent de prix plancher aux producteurs de blé et d'orge de la Saskatchewan. Pour cela, on s'est basé sur un modéle à ajustement partiel de type Nerlovian et les attentes rationnelles. Le modèle Nerlovian est particulier en ce sens qu'on suppose que le modèle à ajustement partiel peut s'étendre à de nombreux produits, ce que confirment nettement les données. Le calcul de la part excédentaire du paiement original versé aux producteurs de la Saskatchewan révèle que la politique du paiement initial n'entraîne que de très légères perturbations sur le marché.     

A SIMULATION MODEL TO EVALUATE THE TIME-QUANTITY RESPONSE IN SPECIALIZED WHITE VEAL PRODUCTION

The objectives of this study were; to develop a model to simulate the growth of calves marketed as white veal; to use this model to evaluate alternative feeding rations; and to estimate optimal net returns to specialized white veal resources. A set of growth equations for veal calves developed by Van Es of Holland were used in a simulation model to estimate the growth of calves fed milk replacer. The model optimized the feeding system and indicated the optimum market weight strategy for specialized white veal producers. The results suggested that feeding system, mortality rates of calves and input-output prices ratios were all variables that influenced the optimum market weight and that producers should choose a flexible market weight strategy in preference to a single target market weight.
Le but de cette étude est: de mettre au point un model pour simuler la croissanee de veaux destinés à la boucherie; d'utiliser ce model afin d'évaluer diverses RATIONS et d'estimer le bénéfice net optimal provenant des ressources consacrées à cette production. Un ensemble d'équations estimant la croissanee de veaux de boucherie, établi par Van Es de Hollande, est utilisé pour estimer la croissanee de veaux nourris avec des substituts de lait. Se model établi le meilleur système d'alimentation ainsi que le meilleur poids de commercialisation pour les producteurs specialisés en viande de veaux. d'après ces résultats les taux de mortalité, les systèmes d'alimentation et le rapport du prix des inputs et outputs influencent le meilleur poids de commercialisation; et les producteurs devraient choisir une politique adaptative plutôt que de s'arrêter à un poids donné.     

Conflicts of Interest Arising from the Prudent Investor Rule: Ethical Implications for Over-the-Counter Derivative Securities

The Prudent Investor Rule creates a potential ethical dilemma for investment advisors selling over-the-counter financial products issued by their firms. The "opportunity" to defraud investors using complex, over-the-counter derivative securities designed for client-specific risk management is much higher than for exchange traded securities. This paper emphasizes the ethical responsibility held by trustees and their organizations to eliminate potential conflict of interests through internal control and monitoring. Independent evaluations of the performance of investment advisors and independent appraisals of complex over-the-counter securities are important in reducing the risks of conflicts of interest. Recent lessons learned from the corporate ethics crisis and requirements of the 2002 Sarbanes Oxley Act would suggest that conflict of interest must be eliminated with third party validation of derivative pricing. By performing due diligence and validation, the trustee is able to satisfy the requirements under the Prudent Investor Rule.     

Informalization in gig food delivery in the UK: The case of hyper-flexible and precarious work

This article examines the process of informalization of work in platform food delivery work in the UK. Drawing on qualitative data, this article provides new analytical insight into what drives individual formal couriers to both supply and demand informalized sub-contracted gig work to undocumented migrants, and how a platform company enables informal work practices through permissive HR practices and technology. In doing so, this article shows how platform companies are enablers of informal labor markets and contribute to the expansion of hyper-precarious working conditions.     

TAIL FORECASTING WITH MULTIVARIATE BAYESIAN ADDITIVE REGRESSION TREES

We develop multivariate time-series models using Bayesian additive regression trees that posit nonlinearities among macroeconomic variables, their lags, and possibly their lagged errors. The error variances can be stable, feature stochastic volatility, or follow a nonparametric specification. We evaluate density and tail forecast performance for a set of U.S. macroeconomic and financial indicators. Our results suggest that the proposed models improve forecast accuracy both overall and in the tails. Another finding is that when allowing for nonlinearities in the conditional mean, heteroskedasticity becomes less important. A scenario analysis reveals nonlinear relations between predictive distributions and financial conditions.     

Social influence and stakeholder engagement behavior conformity,compliance, and reactance

Following the proliferation of customer engagement behavior research, rising interest is observed in marketing-based stakeholder engagement behavior, which covers any stakeholder's—including a customer's, employee's, firm's, supplier's, competitor's, and so forth—behavioral engagement in his/her role-related interactions, activities, and relationships. However, despite its importance, understanding of the stakeholder engagement behavior concept remains tenuous, is therefore addressed in this paper. We first conceptualize stakeholder engagement behavior as a stakeholder's behavioral manifestation toward his/her role-related interactions, activities, and relationships, followed by an exploration of the effect of influencor-exerted social influence on an influencee's stakeholder engagement behavior. We argue this effect to manifest as stakeholder engagement behavior conformity, -compliance, or -reactance, depending on the influencee's level of acceptance of the influencor's exerted influence. In turn, we propose stakeholder engagement behavior conformity, -compliance, and -reactance to yield cooperation, coopetition, or competition in the influencor/influencee relationship, respectively, as depicted in a conceptual model and an associated set of propositions. By investigating the interface of social influence, stakeholder engagement behavior, and its prevailing relational consequences (i.e., cooperation, coopetition, and competition), our analyses offer novel theoretical acumen and actionable managerial insight.
