The macroeconomics of the labor market: three fundamental views

We distinguish and assess three fundamental views of the labor market regarding the movements in unemployment: (1) the frictionless equilibrium view; (2) the chain reaction theory, or prolonged adjustment view; and (3) the hysteresis view. While the frictionless view implies a clear compartmentalization between the short- and long-run, the hysteresis view implies that all the short-run fluctuations automatically turn into long-run changes in the unemployment rate. We assert the problems faced by these conceptions in explaining the diversity of labor market experiences across the OECD labor markets. We argue that the prolonged adjustment view can overcome these problems since it implies that the short, medium, and long-runs are interrelated, merging with one another along an intertemporal continuum.

旅行社创业管理实现模式的构建——基于系统动力学的视角

目前尚没有学者对旅行社创业管理的实现模式进行系统研究。为了建立旅行社创业管理的实现模式,文章首先回顾相关理论;其次,界定了创业管理、创业绩效和功能要素的相关概念,并在前期调研的基础上,确定了旅行社创业成功的关键因素;再次,通过系统动力学方法确定了创业管理的功能要素,并对这些要素进行了分解;最后,提出创业管理行为是一个动态连续的,从发现机会到实施创业行为,到评估创业行为的不断完善的过程,需要有系统的创业管理逻辑。因此,建立了基于创业文化形成,创业机会、资源匹配下的战略选择和创业绩效评价与反馈的三阶段动态创业管理实现模式。

系统动力学视角下的旅行社导游员引进分析

旅行社是劳动密集型和智力密集型企业,其业务是一项复杂的组织工作和人对人、面对面的服务工作。可以说,人是旅行社的核心,是整个企业的精髓和支柱,也是企业中唯一的能动要素,是最积极和基本的要素。旅行社的发展壮大,离不开人员的引进。同时,旅行社的规模也影响着人才引进的数量,文中在系统动力学视角下,对这一问题进行分析。     

A framework for mapping industrial emergence

The industrial landscape is becoming increasingly complex and dynamic, with innovative technologies stimulating the emergence of new applications, business models and industries. This paper presents a framework for mapping science and technology-based industrial emergence, in order to better understand the nature and characteristics of such phenomena, as a basis for improved strategy development. A full lifecycle perspective is included, emphasizing early stage phases associated with scientific and technological developments, together with key transitions between phases related to the conversion of scientific knowledge to technological capability, application, industrial activity and economic value. Roadmapping concepts are used to map industrial emergence phenomena from various perspectives that cover value creation and capture activities together with demand and supply-side factors. The framework has been tested by developing more than 25 diverse ‘emergence maps’ of historical industrial evolution, building confidence that the framework might be applicable to current and future emergence. Common characteristics of industrial emergence have been identified, including key events and milestones, focusing on a chain of demonstrators that delineate the various phases and transitions.

研究目的:从系统角度分析土地、人口、社会、经济、能源对碳排放的影响作用,并对武汉市2017—2030年不同政策情景下的土地利用碳排放进行模拟,为其低碳发展战略和低碳土地利用规划提供决策依据。研究方法:系统动力学方法。研究结果:(1)建立的城市土地利用碳排放系统动力学模型是有效的;(2)按照目前的发展趋势,武汉市的碳排放总量将保持逐年攀升的趋势;(3)经济的快速发展对武汉市土地利用碳排放量的增加具有显著的影响作用;(4)调整土地利用结构、调整产业结构以及提高能源利用效率都能够有效的减少武汉市土地利用碳排放量,其中调整土地利用结构和调整产业结构的作用效果相对来说更加明显。研究结论:转变经济增长方式、升级产业结构、调整土地利用结构和积极研发先进的低碳科学技术是武汉市低碳发展的重要途径。     

Applying search theory to determine the feasibility of eradicating an invasive population in natural environments

The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts are incorporated into a population model, and the costs of search and control are calculated as functions of the amount of search effort (the decision variable). Simulations are performed on a set of weed scenarios in a natural environment, involving different combinations of plant longevity, seed longevity and plant fecundity. Results provide preliminary estimates of the cost and duration of eradication programs to assist in prioritising weeds for control. The analysis shows that the success of an eradication program depends critically on the detectability of the target plant, the effectiveness of the control method, the labour requirements for search and control, and the germination rate of the plant.     

新制度经济学视角下的中国农地制度变迁：回顾与展望

研究目的:分析总结中国农地制度变迁的路径特征、决定条件和影响因素,并展望进一步研究方向。研究方法:文献分析法。研究结果:(1)改革开放以来的中国农地制度变迁呈现出一个较清晰的路径,即改革始终沿着市场取向、明晰产权、稳定地权的方向演进;(2)农地使用权制度改革的成功源于诱致性变迁与强制性变迁的结合,即弹性的中央政策制定、渐进式的地方实施以及具有学习效应的农户认知三者的有机互动,并体现出制度变迁的"共生演化"特征及其蕴含的"适应性效率";(3)新制度经济学是解释中国经济改革和农地制度变迁的有效工具,然而由于经典的新制度经济学本质上的静态性以及国家理论的缺乏,难以对现实世界的各类制度变迁给出一般化的解释。研究结论:基于经典的新制度经济学,进一步整合行为经济学、机制设计理论、演化博弈论等理论工具,超越"强制性—诱致性变迁"二分法,构建一个真正动态的制度变迁模型是一个重要研究方向。     

Determinants of reverse marketing knowledge transfer potential from emerging market subsidiaries to multinational enterprises’ headquarters

Emerging markets (EM) are becoming increasingly important for multinational enterprises because of their high growth potential and future prospects. The unique circumstances in EM lead to increased pressure to offer creative marketing solutions that can be leveraged across the multinational network. Setting up subsidiaries to tap into these markets offers companies the opportunity to integrate in the local community and access its knowledge-base for local and global innovations. Literature, however, reveals that EM subsidiaries have been largely ignored concerning their potential for reverse knowledge transfer (RKT), and marketing initiatives are expected to be developed in mature, developed markets. Our paper fills this gap in research and contributes to extant literature by identifying factors at unit, relationship and knowledge levels influencing RKT potential specific to marketing knowledge from EM subsidiaries. The conceptual discussion leads to study propositions and conceptual framework.
