PTE,innovation capital and firm value interactions in the biotech medical industry

Unlike previous studies which only focus on the main effect between IC and FV, this research includes PTE with the gap of resource-based view. IC is a key element in creating a competitive advantage, as it has a great influence on FV. A company may put relatively less into IC if it demonstrates higher efficiency. However, previous studies have neglected the fact that relative efficiency and IC affect FV and stock returns directly and indirectly. The research period was from 2006 to 2010 and the main research methods include HRA and DEA. The main research findings include the following. (1) There is a space for improvement in terms of the total technical efficiency. (2) PTE has a significant moderating effect between IC and FV. (3) IC and PTE have a significant influence on FV. (4) Apart from PTE and stock returns, IC and FV show significant differences within the sub-industry.     

Using Simulation and Data Envelopment Analysis to Compare Assembly Line Balancing Solutions

This paper presents a technique for comparing the results of different assembly line balancing strategies by using Data Envelopment Analysis (DEA). Initially, several heuristics--which can be thought of as assembly line balancing strategies--were used to solve seven line-balancing problems. The resulting line balance solutions provided two pieces of information that were of particular interest: the number of workers needed and the amount of equipment needed. These two items were considered inputs for DEA. The different line balance solutions were then used as layouts for simulated production runs. From the simulation experiments, several output performance measures were obtained which were of particular interest and were used as outputs for DEA. The analysis shows that DEA is effective in suggesting which line balancing heuristics are most promising.

How Safe Are the Harbors?

Abstract

With the growth of e-commerce has come the need for businesses to provide protection of personal, private data collected from internet users and consumers. The United States has favored a policy of industry self-regulation, while the European Union (EU) has responded to its consumer demands for privacy protection regulations and enforcement. Faced with the critical need for a middle ground, the US has proposed “Safe Harbor Privacy Principles” as a means of compromise with the EU. This article explores the market context of the Safe Harbor Principles, the European reaction, and the probable impact on businesses.

Determinants of Entry in Turkish Manufacturing Industries

The entry of new firms into markets plays an important role in efficient resource allocation and evolution for long term economic growth. Employing dynamic panel data techniques, this paper investigates entry behavior in 66 four-digit Turkish manufacturing industries for the 1993–1999 period. The results of this paper suggest that potential entrants observe the market before the entry takes place; entry is, in general, a follow-up process; and incumbent firms seem to collude to prevent entry in Turkish manufacturing industries. In addition, the real interest rate appears to be a very important determinant of entry decision.

Dynamic efficiency assessment of the Chinese hotel industry

The paper introduces for the first time a totally dynamic two-stage approach to analyzing the hotel industry's technical efficiency at the sub-national level. The first stage uses data envelopment window analysis (DEWA) to assess regional hotel sectors' technical efficiency over time. Unlike previous studies, the second stage uses a dynamic Tobit model to investigate the impact of macro contextual factors on the hotel sector efficiency. The study chooses the Chinese hotel industry during the period 2001-2006 as its application setting. The findings of the investigation indicate that the Chinese hotel industry is approaching an efficient operation in general, recovering from a major dip in 2003 resulting from the Severe Acute Respiratory Syndrome (SARS) outbreak. In addition, the study introduces a novel two-dimensional efficiency-based matrix to assess the competitive advantage of different regions of the Chinese hotel sector. The paper presents strategic market implications for hoteliers, government decision-makers, and destination management organizations. The proposed methods are applicable for situations in which an exogenous event of a destabilizing impact (e.g., SARS) does occur.

流通业增加值占GDP比重变化规律研究——基于我国省级面板数据的实证分析及理论解释

在经济发展过程中,流通业增加值占GDP比重的变化规律很少受到关注。2001年,Anderson和Betancourt指出流通业增加值占GDP的比重和经济增长的长期关系呈倒U型,并运用跨国面板数据进行了实证分析,但没有给出理论解释。选取我国各省1993-2008年的数据,建立静态面板数据模型,对流通业比重和经济发展水平的关系进行了实证分析,结果表明我国流通业比重存在先升后降的倒U型规律。将流通服务看作流通部门的产出,构建流通部门的CES生产函数,对这一规律进行了理论解释。研究启示是:流通业比重变化存在客观规律,不能因流通业属于传统服务业而忽视甚至试图降低其在GDP中的比重,需要遵循这一规律,为服务业结构优化和升级提供相应的政策支持。
