Non-stationary additive utility and time consistency

Within a continuous time life cycle model of consumption and savings, I study the properties of the most general class of additive intertemporal utility functionals. They are not necessarily stationary, and do not necessarily multiplicatively separate a discount factor from “per-period utility”. I prove rigorously that time consistency holds if and only if the per-period felicity function is multiplicatively separable in $t$, the date of decision and in $s$, the date of consumption, or equivalently, if the Fisherian instantaneous subjective discount rate does not depend on $t$. The model allows to explain “anomalies in intertemporal choice” even when the agents are time consistent and various empirical regularities. On the other hand, the model allows to characterize mathematically the “effective consumption profile” of naive, time-inconsistent agents.     

锚企业与科技新城共生模式研究:以阿里巴巴和杭州未来科技城为例

以阿里巴巴和杭州未来科技城为例，采用Logistic模型探讨锚企业与科技新城共生模式，结果表明：总体而言，阿里巴巴和未来科技城属于互利共生模式，阿里巴巴成长会促进未来科技城发展，而未来科技城发展也会反哺阿里巴巴的成长。2013-2016年两者共生系数之间的差值不断缩小，表明阿里巴巴和杭州未来科技城的共生模式从偏利共生转向互利共生。     

What about people in cycle network planning? applying participative multicriteria GIS analysis in the case of the Athens metropolitan cycle network

The bicycle is gaining ground as an inexpensive, fast, healthy, and enjoyable mode of transport, but the development of cycle infrastructures appears to be a necessary prerequisite for supporting further growth in cycling rates. Thus far, few studies have developed comprehensive methodologies for the prioritisation of cycling infrastructure investments, and the role of end users has been underestimated in this process. The unique relationship that cyclists develop with the bicycle itself, their co-cyclists, bicycle facilities, and the urban environment as a result of sensory, kinaesthetic, symbolic, or even political reasons can assist in designing cycle facilities that are more efficient and closer to fulfilling the needs and desires of users. We propose a comprehensive four-step methodology for cycle network planning, which both accounts for the city structure and the zones in which higher cycling demand is possible and uses participative multicriteria GIS processes to incorporate cyclists’ views with regard to choosing the cycle network segments. Our case study is Athens, Greece, where cycling facilities are few and heavily fragmented, although cycling demand has recently grown. This methodology may be useful for cities attempting to introduce and prioritise cycling infrastructures because it focuses on determining where cyclists would prefer to cycle to make such investments more successful in attracting users.     

An empirical investigation of psychological capital among flight attendants

Our paper develops and tests a research model that examines whether psychological capital (PsyCap) mediates the relationship between servant leadership and work engagement (WE) and whether WE mediates the effect of PsyCap on service recovery performance and life satisfaction. Data were collected from flight attendants with a two-week time lag in three waves and their pursers in the private airline companies in Iran. The results suggest that servant leadership influences WE indirectly only through PsyCap. The results also suggest that WE is a partial mediator between PsyCap and the aforesaid attitudinal and behavioral outcomes. Our study discusses theoretical implications and provides recommendations for managers in the airline industry.     

Lifestyle entrepreneurs and their identity construction: A study of the tourism industry

The present study takes issue with the uniform conceptualization of lifestyle entrepreneurs in previous research by drawing on identity theory and life-story interviews with lifestyle entrepreneurs in Norway. This article aims to show how lifestyle entrepreneurs create their entrepreneurial identity and how this identity informs both their entrepreneurial actions in different ways and how they manage the enterprise. On the basis of a narrative understanding of identity this article differentiates between two dimensions of identity construction: (1) socially and culturally embedded versus independent, and (2) flexible versus stable. The main contribution of this study is that embedded or independent and also flexible or stable identity constructions dominate the identity-construction process for individual lifestyle entrepreneurs. On the basis of the latter this article reports four narrative types of lifestyle-entrepreneur identity construction: (1) the modern, (2) the loyal, (3) the freedom-seeking, (4) and the post-modern lifestyle entrepreneur.     

The Post-entry Performance of Cohorts of Export Starters in German Manufacturing Industries☆

This paper investigates four cohorts of firms from German manufacturing industries that started to export between 1998 and 2002, and follows them for five years after the start. Export starters are a rare species and small in Germany. Around 30–40% of those starters studied became continuous exporters. The share of total exports contributed by export starters of a cohort is tiny in the start year, and it remains so over the years that follow. Contrary to the market selection hypothesis, there is no evidence that productivity in the start year is systematically related to survival in the export market. There is no evidence of a negative impact of a smaller firm size in the start year on the chance of surviving in the export market. Starting with a higher share of exports in total sales, however, tends to increase the probability of continuing to export.
