External knowledge search,absorptive capacity and radical innovation in high-technology firms

Open innovation and absorptive capacity are two concepts based on the idea that companies can leverage the knowledge generated externally to improve their innovation performance. The aim of this paper is to analyse the joint effect of open innovation and absorptive capacity on a firm's radical innovation. Open innovation is expressed in terms of external search breadth and depth strategies and absorptive capacity is described by distinguishing between potential and realized absorptive capacity. In order to test our hypotheses, we carried out empirical research in firms operating in high-technology industries. The results indicate that internal routines and processes for absorbing external knowledge help explain radical innovation as they show a significant effect of potential and realized absorptive capacity. Also, there is a moderating effect of absorptive capacity on open innovation. Specifically, potential absorptive capacity exerts a positive effect on the relationship between external search breadth and depth and radical innovation. Realized absorptive capacity moderates the influence of external search breadth. These findings confirm the complementary nature of absorptive capacity and open innovation search strategies on radical innovation.

Marginal and association regression models for longitudinal binary data with drop‐outs: A likelihood‐based approach

Longitudinal data often contain missing observations, and it is in general difficult to justify particular missing data mechanisms, whether random or not, that may be hard to distinguish. The authors describe a likelihood‐based approach to estimating both the mean response and association parameters for longitudinal binary data with drop‐outs. They specify marginal and dependence structures as regression models which link the responses to the covariates. They illustrate their approach using a data set from the Waterloo Smoking Prevention Project They also report the results of simulation studies carried out to assess the performance of their technique under various circumstances.     

Robustness of testing the equality of two slopes in simple linear structural relationships

The usual test of the equality of two slopes in a simple structural relation-ship is the test formed from the normal approximation using the Fisher information matrix, assuming two explanatory variables are independent. This paper examines the robustness if the explanatory variables are, in fact, dependent. A more efficient estimator is derived for a matched pair situation.

关于再就业的现状与对策的一些思考——芷江西路街道个案研究

笔者在芷江西路街道实践活动的主要任务是完成“再就业的现状及对策”这一课题的材料收集工作。材料的收集过程比想象的要困难、复杂得多。一开始,由于居委会关于失业、下岗人员的记录不全面,笔者只得到街道劳动科查找有关资料并按性别、姓名、年龄、文化程度、原单位、再就业单位、失业原因制

论我国企业股票期权激励制度的推进与改进

近年来 ,股票期权已经成为中国经济界和企业界共同探讨的一个热门话题。十几年来美国等西方国家在此方面的成功实践充分证明了股票期权在激励企业经营者、减少代理成本、改善治理结构、促进稳健经营等方面的巨大优越性。但是 ,作为一种全新的激励分配制度 ,由于理论上的匮乏及实践上的欠缺 ,对我国广大企业而言 ,股票期权还是一个新生事物 ,还极不成熟与规范 ,在现行制度及技术上还存在着很多障碍 ,并未能发挥出其应有的作用。本文将对处于摸索中的该制度的实施与完善从理论及实践上作相关探讨
