Intermediate Inequality and Welfare: The Case of Spain, 1980–81 to 1990–91

The 1990–91 household expenditures distribution in Spain dominates, in the relative ("rightist") Lorenz sense, the 1980–81 distribution, but the latter dominates the former in the absolute ("leftist") Lorenz sense. This situation constitutes a textbook case for intermediate or "centrist" notions of inequality and social welfare. This paper presents the first empirical application of this sort, using the intermediate inequality concept introduced in Del Río and Ruiz-Castillo (2000). The data reveal that there is a decrease in household expenditures inequality for a relatively small set of centrist attitudes.     

Designing business models in circular economy: A systematic literature review and research agenda

The concept of circular economy is increasingly receiving attention in different domains, including strategic management, operations management, and technology management. It requires companies to design their business model (i.e., the value network, the relationships with the supply chain partners, and the value propositions towards customers) around a new concept of sustainable development that reduces consumption of natural resources and preserves the environment. However, extant research falls short in terms of explaining how companies design their business model according to the circular economy principles. Starting from this premise, the present paper provides a systematic review of the literature on the design of business models in the context of circular economy, aiming to offer an overview of the state of research and outline a promising research agenda.     

Institutions and Firms' Productivity: Evidence from Electricity Distribution in the EU

Firms' productivity is influenced by internal and external institutions. Ownership is the core internal institutional feature of the firm, while the most important external institutional feature is the quality of government, which shapes the environment in which firms operate. We explore the relative role of these factors and their interaction in determining total factor productivity of electricity distribution firms in 16 EU countries. Using data from the Amadeus database of balance‐sheet information and from the Quality of Governance database, we find that when the quality of government is poor, public ownership is associated with lower productivity levels; however, public ownership is associated with higher productivity in countries characterized by higher quality of the institutional environment.     

HEGY Tests in the Presence of Moving Averages*

We analyze the asymptotic distributions associated with the seasonal unit root tests of Hylleberg et al. (1990) for quarterly data when the innovations follow a moving average process. Although both the t‐ and F‐type tests suffer from scale and shift effects compared with the presumed null distributions when a fixed order of autoregressive augmentation is applied, these effects disappear when the order of augmentation is sufficiently large. However, as found by Burridge and Taylor (2001) for the autoregressive case, individual t‐ratio tests at the semi‐annual frequency are not pivotal even with high orders of augmentation, although the corresponding joint F‐type statistic is pivotal. Monte Carlo simulations verify the importance of the order of augmentation for finite samples generated by seasonally integrated moving average processes.     

Do online discounts and free gifts damage brand image of service? The moderating role of promotion-proneness

The present paper outlines a study based on an experimental design that investigated the effect of online price discounts and free gifts on consumers’ evaluation of the brand, in the context of an airline. The study also analyzed whether promotion-proneness exercises a moderating effect on this relationship. It was found that discounts generate a more positive brand image than free gifts among promotion-prone users, while for less promotion-prone individuals, the opposite is true. The results will help managers to select the most appropriate online sales promotion type for reaching different consumer groups, depending on their promotion-proneness, in line with the needs and objectives of the service firm.     

The evaluation of a surveillance system for violent and non-intentional injury mortality in Colombian cities

Since 2002, the Institute for Peace Promotion and Injury/Violence Prevention (CISALVA) at the Universidad del Valle, Cali, Colombia and the Colombia Program at Georgetown University have developed and implemented 21 epidemiologically based municipal crime observatories in intermediate-sized municipalities in Colombia. These crime observatories serve as monitoring centres that provide low cost, geo-referenced methods of data collection and analysis, which allow cities to develop more responsive policies and prevention programmes and enhance governance. This article focuses on the methodology employed and lessons learned that may be applicable to similar settings. Worth noting within the results was a significant decrease in homicides after the first year of the programme. Whether or not such results could be attributed to the method or to the nature of the interventions and policy initiatives stemming from it remains open to conjecture.     

Breaking Collusion in Auctions through Speculation: An Experiment on CO2 Emission Permit Markets

The European Emission Trading Scheme (EU‐ETS) has chosen to adopt an auctioning procedure to initially allocate CO₂ emission permits. Free allocation of permits will become an exception for the third phase (2013–2020) and most firms will have to buy all their permits on the market or via auctions. The ability of bidders to collude is a key concern about the design of the auction format. To counter collusion, the auction can be open to bidders without compliance obligations (speculators). This paper aims at studying experimentally speculation as a collusion‐breaking device in two different auction mechanisms: the uniform‐price sealed‐bid auction and the ascending clock auction. Our results suggest that a uniform sealed‐bid auction open to speculators should be chosen from a revenue maximization point of view. In this mechanism, compliance agents adopt an aggressive strategy toward speculators. This strategy significantly increases the seller's revenue, compared to the more collusive clock auction. In the latter, on the contrary, bidders accommodate speculators, letting them buy permits in the auction and buying their necessary permits on the secondary market. However, as opening the auction to speculators deteriorates efficiency, the regulator faces a trade‐off between these two objectives.     

THE EMPIRICAL MEASUREMENT OF RENT‐SEEKING COSTS

Abstract This survey focuses on the efforts, carried out mainly by public choice scholars, to measure the social cost of rent seeking. The concept, introduced by Gordon Tullock in 1967 and coined by Anne Krueger in 1974, is well known and accepted by the profession, but its empirical measurement has fallen behind with respect to its theoretical formulation, an often criticized lack in the literature. Although there are good general surveys, none has specifically focused on reviewing the empirical efforts made to measure the phenomenon. The purpose of this paper is to provide such a survey.     

The rest of me

iPhone Siri demonstratively introduced natural language processing. Still a gadget, the idea revived one of the old promises of computers as personal assistants. Does it have the potential of fulfilling the already burgeoning imagination related to this promise? The authors believe that, while still dependent on the evolution of artificial intelligence, the virtual assistant may find support in the already maturing technologies of augmented reality and, more important, in the changing global network with the semantic web, Internet of things and geo-location. Bluntly speaking, its feasibility and acceptability may not even have to wait for the promised IBM computer with human brain capabilities, but rather build on a more friendly interaction with the Google search engine.The article provides a narrative scenario of the deep economic and social transformations and even turbulence that the so called imaginary friend may produce. Not discarding, but creatively integrating some of the archetypes of futuristic literature, the story positions these entities as the foreground of a deep integration of networks, with the added turmoil caused by economic interests that go beyond individuals’ sense-making capacity.This article is one of the follow-ups of the international foresight workshop “Crazy futures” coordinated by Ziauddin Sardar and George Cairns in a small resort on the Danube Delta in July 2011, a workshop organised as part of the project Quality and Leadership for Romanian Higher Education.
