When hubs forget,lie, and play favorites: Interpersonal network structure,information distortion,and organizational learning

The interpersonal network structure of an organization directly influences the diffusion and recombination of ideas and can thus facilitate or impede organizational learning. Most interpersonal networks have ‘hubs’—individuals who have significantly more connections than does the average member. This raises important questions about how hubs influence organizational learning outcomes. Does the presence of hubs improve or impair performance? What happens if hubs forget or misrepresent information that is transmitted through the network? Using simulation models, we find that moderately hubby networks outperform both very hubby and democratic networks. We also find that moderate amounts of information omission or misrepresentation can be surprisingly beneficial to performance, though the patterns of their effects are strikingly different.

National information and euro area monetary policy: a generalized ordered choice approach

We empirically analyze the influence of inflationary pressure originating from persistent national misalignments on the ECB’s interest rate decisions between 2000 and mid-2010. To do so, we introduce an indicator that summarizes the threat to euro area price stability originating from self-reinforcing expected inflation differentials. The indicator is computed based on persistent deviations of national expected inflation and GDP growth rates from the corresponding euro area aggregate. It thereby captures area-wide excess demand pressure on the euro area inflation rate. In order to determine the information content of this indicator, we add it to an empirical monetary policy reaction function. We then analyze this reaction function in the framework of a generalized ordered choice model that fits the data a lot better than its commonly used, more restricted counterpart. Within this empirical framework, we find that after controlling for several area-wide aggregates, national information does not provide additional information that is indicative of the ECB’s policy rate decision.     

The Home Bias in Equities and Distribution Costs

We show that incorporating distribution costs into a general equilibrium model of international portfolio choice helps to explain the home bias in international equity investment. Our model is able to replicate observed investment positions for a wide range of parameter values, even if agents have an incentive to hedge labor income risk by purchasing foreign equity. This is because the existence of a retail sector affects both the correlation of domestic returns with the domestic price level and the correlation between financial and non‐financial income.     

Durability Versus Concentration as an Explanation for Price Inflexibility

We document the extent of price rigidity across United States manufacturing industries in the 1980s and early 1990s and compare rigidity across different phases of the business cycle. We measure price rigidity in three ways – each under four different sets of assumptions. We take an approach that relies on disaggregated data; we look at price patterns for over 4000 individual manufactured commodities. Both durability and seller concentration are found to be important factors explaining differences in price rigidity across industrial product classes. Using our data, we replicate the regression results found in Carlton (1986) that were based on actual transaction prices from the 1960s.     

Virtual Reality and Innovation Potential

This article examines how companies can harness virtual reality (VR) technology to help make themselves more innovative. VR has some unique characteristics which, taken together, can help companies to develop three features common to many innovative organisations: a capacity to experiment in depth; involvement of all in the innovation process; and an ability to capture ideas generated in the innovation process. However, some obstacles need to be overcome before VR fulfils this potential.     

Ethnic-immigrants in founding teams: Effects on prospector strategy and performance in new Internet ventures

We investigated differences in strategy and performance between new Internet ventures with ethnic-immigrant members in the founding team and a matched set of Internet ventures with non-ethnic-non-immigrant team members. Results showed that new ventures with an ethnic-immigrant presence in the founding teams tended to pursue a more aggressive prospector strategy than those with non-ethnic-non-immigrant founding team members. Still, performance of the two groups of ventures was comparable. However, the positive effects of ethnic-immigrant presence on founding teams depended on team size and average age of the founding team members.     

International Framework Agreements and Industrial Relations Governance: Global Rhetoric versus Local Realities

The article discusses the local impact of international framework agreements (IFAs). It presents findings from empirical research carried out in two Spanish MNCs, and it examines how the commitments stipulated by the texts of the IFAs translate in local practice in different subsidiaries in Central and South America. The article follows the policy cycle of both agreements, and it further evaluates them as emerging private institutions of global industrial relations governance. The main findings reveal a paradox. The generic character of IFAs encourages corporate consent for their adoption, but, in practice, it gives precedence to local laws and hence renders the enforcement of compliance difficult, and, in some cases, unfeasible. And where local laws contravene or lack compatibility with International Labour Organization conventions, the central premise of IFAs as instruments of global governance is largely undermined.     

Evidence on the internal labor market during a process of rapid economic growth

We examine the nature and extent of labor market segmentation in Brazil through a survey of 82 modern sector firms in São Paulo. Hiring, training and promotion patterns are found to differ significantly between occupations and a key to understanding these patterns is the nature of skill acquisition, particularly ‘learning on the job’. Furthermore the presence of skill- specificity and internal labor markets for supervisory personnel provide a possible explanation for why relative wages have widened during Brazil's period of rapid economic growth.     

以“客房之声”制定运营战略

客户之声的管理方法自20世纪90年代早期进入管理主流以来,现已大大推动了无数产品的设计。越来越多的企业正从其客户那里收集一手资料,然后将这些信息应用于产品开发决策和流程之中,通过这种努力,这些公司获得了决定性的竞争优势。然而,目前只有少数企业将客户之声的信息广泛应用于业务与运营战略的其它方面。
