Procedural rationality and happiness

The economics of happiness already recognizes how procedures affect the evaluation of outcomes, although this has only been looked at within the standard framework of substantial rationality. This paper aims to go beyond that kind of approach by linking happiness and procedural rationality, focusing on ‘happiness for choice’ (the individual's perceived satisfaction after the decision-making process). Simon's model shows the need for defining aspirations whose values are adapted to the past experience in a given environment. Some remarks proposed by Scitovsky's allow to extend this idea considering the role of creative representation of the world as a way for trying to go beyond the past. These ideas are tested using data on aspirations and satisfaction expressed by students attending an economic course.     

The influence of familiarization sessions on the stability of ramp and ballistic isometric torque in older adults

Ramp isometric contractions determine peak torque (PT) and neuromuscular activation (NA), and ballistic contractions can be used to evaluate rate of torque development (RTD) and electrical mechanical delay (EMD). The purposes of this study were to assess the number of sessions required to stabilize ramp and ballistic PT and to compare PT and NA between contractions in older adults. Thirty-five older men and women (age 63.7 ± 3.7 yr, body mass 64.3 ± 10.7 kg, height 159.2 ± 6.6 cm) performed 4 sessions of unilateral ramp and ballistic isometric knee extension, 48 hr apart. PT significantly increased (main time effect p < .05) from the first to the third session, with no further improvements thereafter. There was a trend toward higher PT in ballistic than in ramp contractions. No difference between contraction types on EMG values was observed. Therefore, the authors suggest that 3 familiarization sessions be performed to correctly assess PT. In addition, PT, NA, RTD, and EMD can be assessed with ballistic contraction in older adults.     

Life-Spheres,Networks, and Sustained Participation in Social Movements: A Phenomenological Approach to Political Commitment

This article proposes an account of individual participation in social movements that combines structural and cultural factors. It aims to explain why certain activists continue to be involved in social movements while others withdraw. When activists remain embedded in social networks relevant for the protest issues and, above all, when they keep a symbolic linkage between their activism and their personal life-spheres, sustained participation is likely to occur. When these two factors become progressively separated from each other and the process of self-interaction by activists loses its strength, disengagement can be expected. The argument is illustrated with life-history interviews of activists who have kept their strong commitment to a major organization of the Swiss solidarity movement, and others that, in contrast, have abandoned their involvement. The findings support the argument that the interplay of the structural positions of actors and the symbolic meanings of mobilization has a strong impact on commitment to social movements and hence on sustained participation or disengagement. In particular, the interviews show the importance of a sense of coherence and of a holistic view of one's personal life for keeping commitment over time. This calls for a view of individual participation in social movements that draws from social phenomenology and symbolic interactionism in order to shed light on the symbolic (subjective) dimensions of participation, yet without neglecting the crucial role played by structural (objective) factors.     

On S-Convexity and Risk Aversion

The present note first discusses the concept of s-convex pain functions in decision theory. Then, the economic behavior of an agent with such a pain function is represented through the comparison of some recursive lotteries.     

Identification of vector AR models with recursive structural errors using conditional independence graphs

In canonical vector time series autoregressions, which permit dependence only on past values, the errors generally show contemporaneous correlation. By contrast structural vector autoregressions allow contemporaneous series dependence and assume errors with no contemporaneous correlation. Such models having a recursive structure can be described by a directed acyclic graph. We show, with the use of a real example, how the identification of these models may be assisted by examination of the conditional independence graph of contemporaneous and lagged variables. In this example we identify the causal dependence of monthly Italian bank loan interest rates on government bond and repurchase agreement rates. When the number of series is larger, the structural modelling of the canonical errors alone is a useful initial step, and we first present such an example to demonstrate the general approach to identifying a directed graphical model.     

There is more to contracts than incompleteness: a review and assessment of empirical research on inter-firm contract design

This paper aims at achieving a greater understanding of how contracts operate in practice through a review of recent empirical literature on inter-firm contract design. Our focus on the structure of contractual agreements differentiates this review from others that dedicated ample coverage also to the antecedents of the decision to contract and of the choice of contracting versus integration. Our framework develops Stinchcombe’s (Organization Theory and Project Management, 1985) hypothesis that contracts are an organizational phenomenon. This allows us to uncover considerable but unevenly distributed evidence on a number of organizational processes formalized in relational contracts, which partially overlap with the processes that are observed in integrated organizations. It also enables us to describe contracts in terms of a larger number of dimensions than is commonly appreciated. The paper summarizes the evidence by proposing a general and tentative framework to guide the design of relational contracts, discusses a number of lingering issues, and outlines directions for further research on contracts as an organizational phenomenon.

The Transition from Temporary to Permanent Employment: Evidence from Tuscany

Abstract. In this paper, by distinguishing between the decisions made by the workers and those made by the firms, we provide a probabilistic evaluation of the transition from temporary to permanent employment in a regional context. Specifically, by exploiting a multinomial nested logit strategy of estimation, we find that the transition to a permanent job is far from certain, especially for women and older workers.

Within-Animal Variation as an Indication of the Minimal Magnitude of the Critical Effect Size for Continuous Toxicological Parameters Applicable in the Benchmark Dose Approach

In this study, the within-animal variation in routinely studied continuous toxicological parameters was estimated from temporal fluctuations in individual healthy nonexposed animals. Assuming that these fluctuations are nonadverse, this within-animal variation may be indicative of the minimal magnitude of the critical effect size (CES). The CES is defined as the breaking point between adverse and nonadverse changes in a continuous toxicological parameter, at the level of the individual organism. The total variation in the data from individual nonexposed animals was divided in variation parts due to known factors (differences in sex, animal, and day) and a residual variation, by means of analysis of variance. Using the residual variation and the estimated analytical measurement error of a toxicological parameter, the within-animal variation can be estimated. The data showed within-animal variations ranging between 0.6% and 34% for different clinical chemistry and hematological parameters in 90-day rat studies. This indicates that different (minimal) CES values may be applicable for different parameters.
