Visualizing and managing value creation through integrated reporting practices: a dynamic resource-based perspective

The article builds on the current debate on how accounting tools can assist top management teams to manage their resources, while communicating a variety of data and information about value creation to their stakeholders. Within this debate, the study focuses on a recent tool for corporate reporting, the Integrated Reporting (〈IR〉), and investigates its utility to support the development of a holistic model for managing strategic resources to create value. To operationalize the 〈IR〉 according to this perspective, the article combines 〈IR〉 with the Dynamic Resource-Based View (DRBV) of the firm on the basis of their common idea that strategic resources are interconnected and have to be managed with the collaboration of all stakeholders in order to inform governance actions and create value with a holistic perspective. For the two case studies analyzed, the information provided by the two organizations’ 〈IR〉 is specifically organized and re-framed using “resource mapping”, which is a DRBV-based visual and analytical technique representing the causal relationships between resources and governance actions. In this way, we not only aim to re-organize and visualize existing information into a new form, but we also expect to describe and communicate the dominant logic in the business and the leverage points where the value creation process lies, supporting the usefulness of Integrated Reporting as a management and governance tool.

     

Quantitative comparisons between finitary posterior distributions and Bayesian posterior distributions

The main object of Bayesian statistical inference is the determination of posterior distributions. Sometimes these laws are given for quantities devoid of empirical value. This serious drawback vanishes when one confines oneself to considering a finite horizon framework. However, assuming infinite exchangeability gives rise to fairly tractable a posteriori quantities, which is very attractive in applications. Hence, with a view to a reconciliation between these two aspects of the Bayesian way of reasoning, in this paper we provide quantitative comparisons between posterior distributions of finitary parameters and posterior distributions of allied parameters appearing in usual statistical models.     

Collective consumption: an application to the passive drinking effect

This study introduces a new collective complete demand system with individual Engel effects that is easy to estimate and permits undertaking policy analysis at the individual rather than household level. Previous estimations of collective demand were limited to single equations. The empirical application investigates the passive drinking effect, that is, whether consumption of alcohol affects the distribution of resources among household members and their level of wellbeing. The results show that a high level of alcohol consumption of one household member significantly affects the allocation of household resources and suggest thought-provoking policy implications.     

Compulsion mechanisms: state-movement dynamics in Buenos Aires

The article reveals and explains the workings of generally ignored mechanism of state–movement interaction proposed by Charles Tilly, namely the compulsion mechanism. Specifically, two types of compulsion mechanisms will be defined: compulsive support and compulsive control. In both types, without using physical repression, the state’s institutions reinforce the movement’s identity while also prompting it to adapt its repertoire of strategies to the state institutions’ requirements. Empirically, this article focuses on the interaction of the assembly movement with the state in the City of Buenos Aires. This movement emerged as a result of the socioeconomic and political crises of 2001–2002 in Argentina. Based on ethnographic fieldwork and archival research, the purpose is to unpack how the assembly movement’s identities and strategies were built and how its interaction with the state evolved.     

On the finite-sample properties of conditional empirical likelihood estimators

We provide Monte Carlo evidence on the finite-sample behavior of the conditional empirical likelihood (CEL) estimator of Kitamura, Tripathi, and Ahn and the conditional Euclidean empirical likelihood (CEEL) estimator of Antoine, Bonnal, and Renault in the context of a heteroscedastic linear model with an endogenous regressor. We compare these estimators with three heteroscedasticity-consistent instrument-based estimators and the Donald, Imbens, and Newey estimator in terms of various performance measures. Our results suggest that the CEL and CEEL with fixed bandwidths may suffer from the no-moment problem, similarly to the unconditional generalized empirical likelihood estimators studied by Guggenberger. We also study the CEL and CEEL estimators with automatic bandwidths selected through cross-validation. We do not find evidence that these suffer from the no-moment problem. When the instruments are weak, we find CEL and CEEL to have finite-sample properties—in terms of mean squared error and coverage probability of confidence intervals—poorer than the heteroscedasticity-consistent Fuller (HFUL) estimator. In the strong instruments case, the CEL and CEEL estimators with automatic bandwidths tend to outperform HFUL in terms of mean squared error, while the reverse holds in terms of the coverage probability, although the differences in numerical performance are rather small.     

Savage in the Market

We develop a behavioral axiomatic characterization of subjective expected utility (SEU) under risk aversion. Given is an individual agent's behavior in the market: assume a finite collection of asset purchases with corresponding prices. We show that such behavior satisfies a “revealed preference axiom” if and only if there exists a SEU model (a subjective probability over states and a concave utility function over money) that accounts for the given asset purchases.     

Becoming a Culturally Responsive Special Educator Amidst School/University Partnerships: Teaching and Learning in Boundary-Zone Activity

This study presents an activity theory analysis of how special educators learn about culturally responsive practices amidst school–university partnerships. Particular attention was paid to how culturally responsive pedagogy was privileged and appropriated by an in-service and a pre-service teacher in a boundary-zone activity. Findings demonstrate how culturally responsive pedagogy was appropriated in light of previous pedagogical artifacts that preexisted in the activity system of the classroom and as a result it became a covert form of instructionism
