A utility representation theorem with weaker continuity condition

We prove that a mixture continuous preference relation has a utility representation if its domain is a convex subset of a finite dimensional vector space. Our condition on the domain of a preference relation is stronger than Eilenberg (1941) and Debreu (1959, 1964), but our condition on the continuity of a preference relation is strictly weaker than the usual continuity assumed by them.     

Control and its role in the process of ensuring knowledge continuity

With the commencement of the 21st century, the information age, knowledge economy and integration of information and knowledge among production factors, organizations show increasing interest in knowledge management. Managers are trying not only to preserve knowledge and transfer it efficiently within their organization, but also to ensure that it is not lost when a knowledge employee leaves the organization. Therefore, it is indispensable for organizations to monitor, record, transfer and preserve their knowledge. In order to ensure efficient preservation of knowledge by the organization, it is essential to integrate the area of the so-called knowledge continuity into the general management and ensure its maximum value. The goal of the article is to identify the role of control in the transformation process and its impact on ensuring knowledge continuity within the organization. A partial goal lies in identifying output quality control by means of productivity One of the conclusions of the article is that in today＇s economic situation, ignoring the existence of knowledge continuity could result in a crisis of management of knowledge and its loss.     

Attitude and consciousness of Japanese men and women towards career commitment and continuity: the role of expected change in HRM policies

A survey was conducted on 302 working men and women in Japanese private firms and local government organization anrl 51 non-working Japanese women to examine the attitude and consciousness towards career commitment and continuity if organizations adopt some policy formulations in more relaxed ways to accommodate, particularly, Japanese women in the workplace. Many studies have well documented that women’s passive attitude towards career commitment and continuity, as compared to that of men, is the outcome of discriminatory HRM policies and practices in the internal labour market. The ANOVA results show that the attitude on the policy relating to work–home harmonization differs significantly between men and women. As compared to working women, non-working women would have a more positive attitude to career commitment and continuity if a work-home harmonization policy wcre adopted. The ANOVA results also reveal that men and women have shown an almost similar attitude to pay structure and, thus, the integrated corporate pay structure can help in developing women’s attitude and consciousness towards career commitment and continuity, but women cannot share equally with their male counterparts as regards the policy of career development; rather, they are demanding job security, distributive justice and career counselling in the workplace.

Duality Theory of Non-convex Technologies

Duality Theory of production imposes a number of simplifying assumptions regarding the production technology, including various maintained convexity assumptions. Emphasizing the technological information content of alternative models, this paper challenges some widely held views on the role of convexity. The role of convexity in Duality Theory is asymmetric. While convexity is of importance in recovering technology information from economic models, cost functions are concave and profit functions are convex irrespective of convexity of the underlying technology. For recovering technology information from economic models and data, we discuss two alternative approaches: recovering inexact outer-bound approximations; and enriching standard economic models by additional quantity/financial constraints. The main conclusion is that non-convexities should not stop one from applying the Duality Theory.     

The opportunity cost of duality

A dual representation of a technology, e.g., a cost function, may not contain all of the technological information, but it will contain all of the information about input vectors that would be chosen by a cost-minimizing firm. At least this much is clear for deterministic technologies. The main question addressed in this paper is whether the same can be said about stochastic technologies and their dual representations. Despite some pessimism expressed in the stochastic frontier literature on this question, we argue that there is no extra cost imposed in the stochastic case. Thus, the conclusion of this paper is: Just dual it!

FDI与二元经济转型:基于中部地区的理论及实证研究

本文从理论上对FDI促进二元经济转型的途径进行了分析,认为主要途径包括:通过提高剩余劳动力的就业率来促进二元经济转型;通过提高农业部门和非农业部门的产值来影响二元经济的转型。通过中部六省的面板数据对FDI与二元经济转型进行的实证分析,发现农业部门的FDI对二元经济没有明显的影响,而非农业部门的FDI对二元经济有明显的正向影响,可以弱化中部地区的二元经济特征。     

Subdifferentiability and lipschitz continuity in experimental design problems

The calculus of concave functions is a widely accepted tool for optimum experimental design problems. However, as a function of the support points and the weights the design problem fails to be concave. In this paper we make use of generalized gradients in the sense of Rockafellar (1980) and Clarke (1983). A chain rule is presented for the subdifferential of the composition of an information function with the moment matrix mapping. Lipschitz continuity of the global design function is proved and conditions for strict differentiability are given.

城镇化的“土改”路径——以成都统筹城乡改革实践为例

中国城乡土地的"二元性"和农村集体土地产权的"分设性"妨碍了城乡土地、劳动和资本的有效配置,因而也妨碍了中国的城镇化进程.作为重要的生产资料,农村土地配置仍然要回归市场渠道,这是市场经济的基本要求.成都统筹城乡改革实践表明,在国家现有土地制度框架下,在"确权"基础上,通过适时、有针对性地政策调整与改革,农用地、农地转用以及农地经营权的让渡都可逐步采取市场定价途径实现土地资源的有效配置.     

Cost and Production Duality: The Case of the Regulated Firm

This paper examines a generalization of cost-production duality for regulated firms. It derives an equivalency between the production function and conditional factor demands for the case where the firm's optimization problem is subject to a set of additional (regulatory) constraints. This procedure is extended to an optimization problem within a dynamic framework which leads to the recovery of the firm's technology.     

Duality principles and measuring the production technology: A heuristic introduction

There has been growing interest in the use of duality principles to estimate indirectly both the character of the production technology in various industries and the structure of preferences. Much of this material has to date, remained outside most intermediate micro-theory texts. The purpose of this paper is to provide a heuristic discussion of these relations as they are used in evaluating the micro-level production technology. The duality properties are illustrated using a neoclassical cost function and recent empirical examples for the issue of economies of scale in electric power production and the role of natural resources for production at the two-digit (SIC code) level of manufacturing.     

经济增长、产业结构与劳动力转移

当前中国经济增长与显性就业之间总体上的不相关根本原因在于一产中大量隐性失业的存在,这些集中在农村的大量剩余劳动力对我国就业压力起到了一个蓄水池的作用。由于中国剩余劳动力具有极为典型的产业间分布特征,因此我们提出了一个不同于托达罗模型的、以劳动力的产业间转移为基本分析框架的模型。之后,我们以改革开放以来我国的经验数据对我们的理论进行了实证检验。
