Issues in the Design of Facilitated Collaboration Processes

Groups often rely on the expertise of facilitators to support them in their collaboration processes. The design and preparation of a collaboration process is an important facilitation task. Although there is a significant body of knowledge about the effects of facilitation, there is a dearth of knowledge about the ways in which facilitators design collaboration processes. Increased understanding in this area will contribute to the effective design and use of collaboration support and to the development of collaboration process design support. The research reported in this paper explores the strategies and techniques facilitators use to design a collaboration process, and the aspects of this task they perceive as challenging. We present the results of a questionnaire among professional facilitators. We compare facilitators with different expertise levels to identify challenges in the design of collaboration processes. We discovered that although the activities performed and information used by novices is not very different from expert practices, their limited experience makes them less flexible. When the actual session brings surprises such as different outcomes or conflict, novices cannot easily adapt their designs to accommodate these.     

Product Innovation Processes in Small Firms: Combining Entrepreneurial Effectuation and Managerial Causation

This article reports a multimethod study of product innovation processes in small manufacturing firms. Prior studies found that small firms do not deploy the formalized processes identified as best practice for the management of new product development (NPD) in large firms. To explicate small firms' product innovation, this study uses effectuation theory, which emerged from entrepreneurship research. Effectuation theory discerns two logics of decision‐making: causation, assuming that means are selected to attain goals; and effectuation, assuming that goals are created based upon available means. The study used a process research approach, investigating product innovation trajectories in five small firms across 352 total events. Quantitative analyses revealed early effectuation logic, which increasingly turned toward causation logic over time. Further qualitative analyses confirmed the use of both logics, with effectual logic rendering product innovation resource‐driven, stepwise, and open‐ended, and with causal logic used especially in later stages to set objectives and to plan activities and invest resources to attain objectives. Because the application of effectuation logic differentiates the small firm approaches from mainstream NPD best practices, this study examined how small firms' product innovation processes deployed effectuation logic in further detail. The small firms: (1) made creative use of existing resources; (2) scoped innovations to be realizable with available resources; (3) used external resources whenever and wherever these became available; (4) prioritized existing business over product innovation projects; (5) used loose project planning; (6) worked in steps toward tangible outcomes; (7) iterated the generation, selection, and modification of goals and ideas; and (8) relied on their own customer knowledge and market probing, rather than early market research. Using effectuation theory thus helps us understand how small firm product innovation both resembles and differs from NPD best practices observed in larger firms. Because the combination of effectual and causal principles leverages small firm characteristics and resources, this article concludes that product innovation research should more explicitly differentiate between firms of different sizes, rather than prescribing large firm best practices to small firms.     

A Sequential Rationality Test of USDA Preliminary Price Estimates for Selected Program Crops: Rice, Soybeans, and Wheat

Despite recurrent evaluations on USDA price forecasts, the performance of USDA price estimates has not previously been examined in publication. To fill the void in research to this important public information, a sequential forecast evaluation procedure is applied to selected USDA price estimates: Rice, soybeans, and wheat. The evaluation procedure reveals that the USDA price estimates are short-run unbiased; however, they are not long-run rational. In addition, short-run optimality and efficiency tests suggest that USDA price estimates need to be properly scaled and fully reflect information embodied in past prices and their estimates — a possible venue to improve the predictability of USDA price estimates for the crops.     

The Impact of Introducing Insurance Guaranty Schemes on Pricing and Capital Structure

The introduction of an insurance guaranty scheme can have significant influence on the pricing and capital structures in a competitive market. The aim of this article is to study this effect on competitive equity–premium combinations while considering a framework with policyholders and equity holders where guaranty fund charges are volume‐based, as levied in existing schemes. Several settings with regard to the origin of the fund contributions are assessed and the immediate effects on the incentives of the policyholders and equity holders are analyzed through a one‐period contingent claim approach. One result is that introducing a guaranty scheme in a market with competitive conditions entails a shift of equity capital towards minimum solvency requirements. Hence, adverse incentives may arise with regard to the overall security level of the industry.     

DYNAMIC HEDGE FUND STYLE ANALYSIS WITH ERRORS‐IN‐VARIABLES

We revisit the traditional return‐based style analysis in the presence of time‐varying exposures and errors‐in‐variables (EIV). We apply a benchmark selection algorithm using the Kalman filter and compute the estimated EIV of the selected benchmarks. We adjust them by subtracting their EIV from the initial return series to obtain an estimate of the true uncontaminated benchmarks. Finally, we run the Kalman filter on these adjusted regressors. Analyzing EDHEC alternative index styles, we show that this technique improves the factor loadings and allows more precise identification of the return sources of the considered hedge fund strategy.     

Travel and activity time allocation: An empirical comparison between eight cities in Europe

A study of daily time allocation to travel and out-of-home activity is conducted across eight European cities over three countries: France (Lyon, Grenoble, Strasbourg and Rennes), Switzerland (Geneva, Bern and Zurich) and Belgium (Brussels), based on individual travel survey data collected between 1997 and 2006. The effects of socio-demographic, spatial context, transport availability and city-specific variables are investigated thanks to the Cox proportional hazard model. The results indicate that socio-demographic characteristics and city (or country) specific effect play a major role while residential density and proximity to high level road or public transport networks have a very limited impact on time budgets for travel and out-of-home activities.     

EXPLAINING RISING INEQUALITY: SKILL‐BIASED TECHNICAL CHANGE AND NORTH–SOUTH TRADE*

Abstract We review the ‘skill‐biased technological change (SBTC) versus North–South trade (NST)’ debate in order to explain widening wage inequality between skilled and unskilled workers. The traditional explanations based on exogenous SBTC and on the North–South Heckscher–Ohlin–Samuelson approach, as well as the early estimates that diagnosed a clear prevalence of the former, are firstly exposed and discussed. A presentation is then made of the recent theoretical literature that endogenizes SBTC, introduces new channels of impacts from NST, and combines both explanations. Finally, the current estimates show that (i) both explanations are relevant, (ii) their impacts differ according to industries and countries, (iii) outsourcing is the main vector of impact from NST and (iv) SBTC and NST interact.     

Institutional changes, wars and stock market risk in an emerging economy: evidence from the Israeli stock exchange, 1945–1960

In an effort to understand the determinants of economic growth in an emerging economy, we analyze the effects of institutional reforms, wars and political events on the risk level of the Israeli stock market between 1945 and 1960. We find that the anticipation of wars did not have any effect but the end of skirmishes actually raised the risk on the stock market. Domestic political instability also increased the stock market risk. Finally we find that most legal reforms did not matter much.

The European Union's accounting policy analyzed from an ethical perspective: The case of petroleum resources,prospecting and evaluation

This article uses Habermasian philosophy as a reading grid to understand the eminently political aspect of international accounting standard-setting. We specifically analyze the accounting regulations specific to the exploration for and the evaluation of mineral resources in the European context. The rise of the IASC and its successor, the IASB, favors the emergence of a new phase in accounting standard-setting, with a shift from a ruling logic to regulations that put the economic and social actors at the forefront of the negotiations. This change is particularly obvious in the notorious exception allowed by IFRS 6 (Exploration for and evaluation of mineral resources) exempting applicants from paragraphs 10–12 of the IAS 8. This example allows us to question the legitimacy of international accounting standardization and the ethical problems it poses.
