Analyzing the effects of social impacts of events on satisfaction and loyalty

The purpose of this study is to examine the social impacts of events on participants’ satisfaction and whether loyalty is a result of this satisfaction when taking attendance to event into consideration. This study uses data from a sample of 542 participants who participated in the Kirkpinar Oil Wrestling Festival. Factor analysis was performed, and the data was sorted into seven different categories: community benefits, cultural and educational benefits, quality of life concerns, community resource concerns, attendance to event, satisfaction, and loyalty. Structural equation modeling was performed, and the hypotheses were tested using bootstrap confidence intervals in addition to classical testing procedures. The hypothesis results showed a direct effect on quality of life concerns and attendance to event. In events on satisfaction, there was also a direct effect on loyalty. In addition, there was an indirect effect on quality of life concerns and attendance to events on loyalty through satisfaction.     

Stochastic resource allocation for containerized cargo transportation networks when capacities are uncertain

We consider the stochastic resource allocation problem for containerized cargo transportation with uncertain capacities and network effects, in which a freight operator needs to allocate a certain amount of capacity to each product to maximize the expected profit. We formulate the problem as a constrained stochastic programming model and provide theoretical results that completely characterize the optimal solution to the model under a special case. Under a general case, we build an approximation model of the problem and propose a sampling based algorithm to solve the approximation model. A number of numerical experiments are offered to test the algorithm.     

消费决策、进口需求与房价变动:理论模型与经验证据

本文探讨在消费选择的机制下房价变动影响进口贸易的路径,并且实证研究我国房价变动对进口贸易的影响程度.通过构建基于消费者跨期选择机制的优化框架,得出了房价对于进口的影响为替代效应和收入效应并存.关键取决于消费者对房屋的购买是否纳入必需品考虑范畴.在此基础上利用31个省市2004-2009年的面板数据进行经验分析,得出:房价每上升1％,进口额会上升0.8％左右.可见,我国房价上升对进口额的影响是替代效应大于收入效应.从我国消费者总体行为上看,在房价上涨到一定程度的条件下,消费者会减少购房而增加进口需求.这也进一步说明在我国,房屋的购买大多不是为了满足基本的生存居住需要,而是作为投资和保值工具.

The optimal entry fee-prize ratio in Tullock contests

We analyze a three-stage game where an organizer sets an entry fee for a Tullock contest event, and a finite population of homogeneous agents simultaneously decide whether to participate or not. We show that in the unique symmetric subgame perfect Nash equilibrium, the larger the population size, the lower the probability the agents enter the contest, but the organizer’s optimal entry fee-prize ratio could either increase or decrease with the population size. When the population size approaches infinity, the number of contestants converges to a Poisson distributed random variable.     

General equilibrium in markets for lemons

This paper studies exchange economies in which agents have differential information about the goods that the other agents bring to the market. To study such a setting, it is useful to distinguish goods not only by their physical characteristics, but also by the agent that brings them to the market. Equilibrium is shown to exist, with agents receiving the cheapest bundle among those that they cannot distinguish from the truthful delivery. An example is presented as an illustration.     

Operations flexibility in events organization

The aim of this study was to understand the interrelation between operations flexibility and the adverse impacts associated with risks in event organization during its execution. For this, a multiple case study was carried out among six Brazilian event-organizing entities. A qualitative study was conducted through structured interviews and deductive content analysis. Data triangulation was obtained by using the post-event reports of events organized by those entities. The study identified strategies used to deal with variability related to the risks present in the execution of events and the interrelation between adverse impacts associated with the risks and the types of operations flexibility used. Furthermore, the authors propose “internal infrastructure flexibility” since operations flexibility literature does not adequately explain the changes in the internal structure found in the field research.     

群体性事件治理新思路——构建预防、预警、预控体系

对于群体性事件的治理，政府应该改变以往应对、处置的传统习惯和做法，转为构建健全的预防体系、高效的预警体系、严密的预控体系，对群体性事件主动出击，在群体性事件出现苗头或者征兆的时候，采取有针对性的预控措施，把群体性事件消灭和控制在萌芽状态。
