Modeling CRS bounded additive DEA models and characterizing their Pareto-efficient points

Dealing with weighted additive models in Data Envelopment Analysis guarantees that any projection of an inefficient unit belongs to the strong efficient frontier, among other interesting properties. Recently, constant returns to scale (CRS) range-bounded models have been introduced for defining a new additive-type efficiency measure (see Cooper et al. in J Prod Anal 35(2):85–94, 2011). This paper continues such earlier work further, considering a more general setting. In particular, we show that under free disposability of inputs and outputs, CRS bounded additive models require a double set of slacks. The second set of slacks allows us to properly characterize all the Pareto-efficient points associated to the bounded technology. We further introduce the CRS partially-bounded additive models.     

Writing Across Contexts: Urban Informality and the State in Tallinn,Bafatá and Berlin

Urban research has long related informality to a lack of state capacity or a failure of institutions. This assumption not only fails to account for the heterogeneous institutional relations in which informality is embedded, but has also created a dividing line between states. Whereas some states are understood to manage urban development through functioning institutions, others, in this view, fail to regulate. To deconstruct such understandings, this article explores informal practices through a multi‐sited individualizing comparison between three case studies of water governance, parking regulation and dwelling regimes in Bafatá (Guinea‐Bissau), Tallinn (Estonia) and Berlin (Germany), respectively. Our approach to understanding informality starts from the negotiation and contestation of order between differently positioned actors in the continuous making of states. From this point of view, informality is inherent in the architecture of states––emerging through legal systems, embedded in negotiations between and within institutions, and based on conflicts between state regulations and prevailing norms. Tracing how order takes shape though negotiation, improvisation, co‐production and translation not only highlights how informality constitutes a modus operandi in the everyday workings of the state in all three cases, but also provides a way to talk across these cases, i.e. to bring them together in one frame of analysis and overcome their presumed incommensurability.     

Productivity change of Portuguese municipalities after local reforms

This article examines the impact of the reforms introduced in the structure of the Portuguese local administration after the bailout agreement in 2011 on the efficiency and productivity of municipalities. In order to determine a measure of productivity change, we apply the global Malmquist productivity index to assess the performance of the 278 Portuguese mainland municipalities for the recent 6-year period 2009–2014. The overall results reveal that there was a decrease in the global productivity until 2013 followed by a notable increase in 2014 basically due to technological changes, thus it seems that the reforms have had a positive effect on the productivity of municipalities.     

Modelling economic circuit flows in a social accounting matrix framework. An application to Portugal

Aggregated Social Accounting Matrices (SAMs) will be built for the Portuguese economy in 1997, 1998 and 1999, based on the country's national accounts statistics. The SAMs will be shown as a working instrument for quantifying the flows in the economic circuit and for simulating the effects resulting from changes in such flows. The economic flows associated with the government subsectors will be emphasized, whilst accounting and fixed-price multipliers will be calculated to facilitate the study of the effects resulting from changes in the government's expenditure, which will also be subjected to a test on their veracity.     

Catalan firms and the distribution of products in Europe

The food industry sector has seen major changes in the ways it needs to compete. Spain became linked to the European Community in the early 1970s by an adherence treaty which regulated food exports to the member countries. Subsequently, when Spain became a full European Community member in January 1986, both exports and imports to and from countries (Mediterranean or otherwise) became regulated. There had not previously been a tradition of trade links with most of these countries. After 10 years of full coexistence with the other European members, it is possible to test the effect of free circulation of goods, the major presence of community multinationals in the markets, the restructuring of the food industry sector, and the penetration of Spanish products in European markets. At present, the objectives of economic convergence contemplated in the Maastricht Treaty call for the control of macroeconomic variables (particularly inflation) which affect the food industry (by virtue of its special characteristics) far more than the remaining sectors because of its peculiarities. This paper is a summary and extension of a broader study conducted by Lourdes Viladomiu (Universitat Autònoma de Barcelona), María de los Angeles Gil Estallo (Universitat Pompeu Fabra), Jordi Melé (Universitat de Barcelona), and Manuel Cantos (Universitat Pompeu Fabra) financed by the Fundació Empresa i Ciència of the Universitat Autònoma de Barcelona.     

Signalling and the Long‐run Performance of Spanish Initial Public Offerings (IPOs)

Abstract:   Academic research into firms that have gone public has focused on the study of two anomalies: initial underpricing and long‐run underperformance. We analyse Spanish Initial Public Offerings to provide additional evidence on the long‐run performance of IPOs and its relationship with initial underpricing. Results reveal the existence of negative long‐run abnormal stock returns, in line with the international literature. Long‐run performance presents a positive relationship with underpricing and the volume of funds obtained in seasoned offerings, in consonance with the predictions of Allen and Faulhaber (1989) , Welch (1989) and Grinblatt and Hwang (1989) .     

Stakeholder influence on corporate strategies over time

Modern management reporting on its company's performance is influenced by individuals ethical considerations. Stakeholders philosophies have continued to change over the last 75 years affecting reporting systems for companies reporting information internally and externally. These fundamental changes in philosophy have affected how information is conveyed. We are not claiming that only one philosophical viewpoint dominates companies reporting practices, but there does appear to be a changing trend of philosophies building on one another. We use resource dependence theory in relationship to a decision-making model to explain changing stakeholders positions over time. This paper argues that six dominant philosophical theories have influenced the way individuals and organizations report financial and other information. Further, these philosophies then are depicted in a model that helps us to understand what influences companies to present themselves to the outside world. A vignette is used to depict changing philosophical views for several companies management report over 75 years.     

A Model Capturing Ethics and Executive Compensation

This article develops and applies a knowledge-based framework for understanding and interpreting executive compensation under the rubric of ethical consideration. This framework classifies six major ethical considerations that reflect issues in compensation design. We emphasize that these six ethical considerations are influenced by liberty and equality concepts. This framework helps to highlight areas where executive compensation has not been well spelled out.     

Cultural and Ethical Effects on Managerial Decisions: Examined in a Throughput Model

Financial and cost accounting information is processed by decision-makers guided by their particular need to support decisions. Recent technological advances impacting on information as well as organizations such as the European Community mandating financial reporting requirements for many countries is rapidly changing the landscape for decision making using accounting information. Hence, the importance of individuals' decision making is more important than it was previously. These decisions are also influenced by individuals' ethical beliefs. The Throughput Modeling approach to cultural and ethical concerns provides a way of dealing with accounting information processed through various pathways by decision-makers. This modeling approach captures different philosophical perspectives from which to understand what is involved in "thinking scientifically." In the Throughput Modeling approach, pathways highlight the importance of how different philosophical perspectives may be used by individuals in arriving at a decision. This paper highlights key concepts involved in rethinking the basis of moral decision making in terms of an underlying process, rather than focusing on the application of principles or the development of a virtuous character. Examples are provided from both English and Spanish settings to help emphasize the importance of modeling ethical decision making globally.
