论破产管理人制度

破产管理人参与破产程序的全过程,具体管理破产程序中的各项事务,是破产程序中一个最重要的组织机构。我国破产法在破产管理人制度方面存在一些缺陷。文章结合我国现行立法的规定,认为我国破产管理人制度应在破产管理人的选任、任职资格、报酬及责任等方面进行完善,使破产程序的目的得以顺利实现。     

基于复杂网络的国际铜材贸易格局演化

基于复杂网络方法构建2001—2021年全球铜材贸易网络刻画其演变特征,运用QAP(二次分配问题)分析法对影响因素进行探究。研究发现：整体上,全球铜材贸易网络规模增大,呈现出明显小世界特征;局部上,德国、中国、美国、意大利是核心枢纽节点,影响世界铜材贸易的格局;影响因素上,国家邻近、经济发展水平差距大会显著促进铜材贸易,地理和制度距离越大会产生抑制,经济自由度、人口及是否使用相同语言不会产生显著影响。鉴于此,应加强与邻近区域合作,加大技术创新研发投入,保障中国铜材产业供应链安全、稳定。     

论公平分配的实现过程

公平分配的实现状况直接关系到和谐社会建设的成败,正确地认识公平分配的实现过程至关重要。现阶段,解决公平问题的重点在初次分配,而不是所谓的二次、三次分配。实现公平是一个渐进的过程,要分阶段按层面进行,不能一刀切,大体可以分为三个阶段、两个层面。由于涉及问题众多,涉及部门无数,每一个问题、每一个部门均有不同特点,所以解决分配问题要形式多样,没有固定的模式。     

Social capital and cultural adjustment of international assignees in NGOs: do support networks really matter?

International assignees face cultural adjustment challenges in their host countries in work and nonwork situations. At the same time, social capital theory suggests that individuals can access and mobilize resources from their social networks. We explore the use of social networks by international assignees from a non-governmental organization in their cross-cultural adjustment to the host country. Specifically, we are interested in the individuals who directly provided support to the expatriate, a network that we term the ‘current assignment support network’. We focus on the size, type and frequency of contact of the international assignee's support network, and investigate to what extent these variables can predict overall cultural adjustment to the host country, or separate dimensions of cultural adjustment such as interaction adjustment, general adjustment and work adjustment. Our findings indicate that certain characteristics of the international assignee's current assignment support network do impact their cultural adjustment to the host country, but that the effects are moderated by whether the assignee has prior international experience.     

A Simple Selling and Buying Procedure

For the assignment game, we analyze the following mechanism. Sellers, simultaneously, fix their prices first. Then buyers, sequentially, decide which object to buy. Also, each buyer may report his or her indifferences (along with the previous buyers' indifferences) to the following buyer. The first phase determines the potential prices, while the second phase determines the actual matching. Reporting truthfully the indifferences is always a dominant strategy for the buyers. Moreover, when buyers state their true indifferences, the subgame perfect equilibria outcomes of the mechanism correspond to the maximum equilibrium price vector together with optimal matchings.

一个特殊指派问题及其解法

运筹学中的通常指派问题是解决总工时最少的问题,但在实际中有许多指派问题是要求所有的工作同时开工的情况下,整项工作尽早地完成。本文研究了这类历时最少的指派问题的数学建模及其线性规划、矩阵变换等解法。     

Optimizing the aerodynamic efficiency of intermodal freight trains

We develop an aerodynamic loading assignment model for intermodal freight trains based on an integer-programming framework to help terminal managers make up more fuel-efficient trains. This is the first use of optimization modeling to address the aerodynamics and energy efficiency of railroad intermodal trains. Several recommendations regarding railway equipment use, operations, and policy are proposed to improve fuel-efficiency and reduce emissions from intermodal transportation. Analysis of one major railroad intermodal route reveals the potential to reduce fuel consumption by 15 million gallons per year with corresponding savings of $28,000,000. Greater benefits are possible through broader implementation of the model.     

政府间财政支出责任划分研究述评

政府间支出责任划分理论方面的研究主要集中于分析框架,其中最具代表性的是Musgrave的"财政三职能"、Oates的财政联邦制理论、Olson的财政均等化原则和Martinez的多维框架理论;实证方面,Musgrave、Martinez等众多学者分别对成熟市场经济国家和转轨国家的支出责任划分情况进行了研究;方法上则主要采用了成本收益法、比较分析法、实验经济学以及第二代财政联邦制理论等研究方法。     

Why does on-farm storage fail to mitigate price volatility?

We analyze the role of farm stock management on price volatility under liquidity constraints and heterogeneous price expectations. In commodity markets, speculative behaviors by stockholders tend to reduce price volatility, but this is not the case in certain agricultural markets, where speculation by farmers regarding decisions to sell or store grain is subject to liquidity constraints and heterogeneous price expectations. Like stockholders, most farmers sell grain if they expect a price drop in the near future, but unlike stockholders, they are not necessarily able to purchase grain if they expect a price increase in the next period. Heterogeneous price expectations can also lead to suboptimal storage decisions, further increasing price volatility. For these reasons, the storage management behavior of farmers often fails to mitigate price drops in the way that speculation by stockholders does. We merge historical data on maize prices and household storage collected in Burkina Faso in order to build a dynamic panel over the 2005–2012 period. We show that carryover from one season to the next is associated with unexpected price drops during the preceding lean season and that carryover is associated with more frequent unexpected price drops following the subsequent post‐harvest season.
