We use Google Search volume to track changes investors' positive and negative market attention. Our results support the hypothesis that this information reflects investors' optimistic and pessimistic anticipation and can be used to predict near-term future returns. We find that changes in negative search term volume of “market crash” and “bear market” and changes in positive search term volume “market rally” explain near-term stock returns. Changes in investors' attention are partly related to past stock market returns, implying that investors are prone to pay attention to possible price reversals. These measures of market attention are potential gauges of investor sentiment. 相似文献

This paper studies productivity dispersion in a retail chain. We find that productivity is highly dispersed between the branches. Furthermore, productivity rankings are quite persistent. Accounting for employee skills and human resource management decreases the productivity dispersion only slightly. The results suggest that productivity dispersion is “real”. 相似文献

Using linked employer-employee data for Finland we examine associations between job design, employee well-being and job-related stress. Three key findings stand out. First, in accordance with the theory of Karasek and Karasek and Theorell, job control and supervisory support are positively correlated with employee well-being and negatively correlated with job-related stress. Second, as predicted by theory, job demands are positively correlated with job-related stress. Third, there is no association between job demands and employee well-being and, contrary to expectations, neither job control nor supervisory support alleviate the negative relationship between job demands and job-related stress. Our results confirm the importance of job design for employee well-being. 相似文献

Aligning Misaligned Systemic Innovations: Probing Inter‐Firm Effects Development in Project Networks
Pauli Alin Antti O. Maunula John E. Taylor Riitta Smeds 《Project Management Journal》2013,44(1):77-93
Implementing systemic innovations in a project network can significantly improve its performance; however, implementing systemic innovations is difficult if project network structures misalign to the innovation. Little research has examined how project network structures can align to systemic innovations. To address this research gap, we studied an advanced building information modeling tool implemented in a Finnish design and development project network. We found that misaligned innovations are aligned through a process of task sequence alignment, knowledge base alignment, and work allocation alignment. Our findings are important; they suggest that implementing systemic innovations in project networks is a multistage inter‐firm process. 相似文献

The effect of corruption on economic growth has attracted interest in empirical development economics. The conventional view of corruption as impediment for growth has been challenged by the ‘grease-on-the-wheels’ hypothesis. We take a new perspective on the issue and suggest corruption as macro risk, referred to as a ‘gamble’ hypothesis. Using cross-country data and two alternative indicators of corruption, we find corruption to be a significant driver of heteroscedasticity in total productivity. This supports the new gamble hypothesis. We also note some misleading interpretations in the previously published frontier applications. To avoid these shortcomings, we apply a flexible semi-nonparametric estimator. 相似文献

Human Resource Management Policies and Productivity: New Evidence from An Econometric Case Study 总被引:1,自引:0,他引:1
First we distinguish various approaches used by economists toassess the impact of human resource management practices onproductivity and then we briefly review and illustrate studiesthat represent different approaches. In the main part of thepaper we illustrate the econometric case study method, by usingnew data to analyse a case from retail trade and by emulatingan approach used in an earlier study. Consistent with theorywe find that when employees have opportunities to participate,and to receive appropriate information and pertinent rewards,a one standard deviation increase of the first principal componentscore would increase productivity by 1 per cent. Our findingsimply that there are benefits to innovative work practices,even in settings where employees do simple tasks and employeesare relatively low-skilled. Since our findings are similar tothose contained in a previous study, our results also indicatethe value of replication studies.

This paper studies a retail chain that introduced a sales incentive plan that rewarded for exceeding a sales target and subsequently cut the incentive intensity in addition to increasing the target. Utilizing monthly panel data for 54 months for all 53 units of the chain the paper shows that the introduction of the sales incentive plan increased sales and profitability, whereas the changes in the plan lead to a marked drop in sales and profitability. Thus, modifying the incentive plan proved costly for the firm. The results are consistent with the gift‐exchange model of labor contracts. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

This paper empirically investigates the index premium and its implications from 1990 to 2005. For additions to the S&P 500 and Russell 2000, we find that the price impact from announcement to effective day has averaged + 8.8% and + 4.7%, respectively, and −15.1% and −4.6% for deletions. The premia have been growing over time, peaking in 2000, and declining since then. The implied price elasticity of demand increases with firm size and decreases with idiosyncratic risk, supporting theoretical predictions. We also introduce a new concept that we label the index turnover cost, which represents a hidden cost borne by index funds (and the indexes themselves) due to the index premium. We illustrate this cost and estimate its lower bound as 21-28 bp annually for the S&P 500 and 38-77 bp annually for the Russell 2000. 相似文献

I analyze the interaction of two institutions, markets and public policies, and their effect on structural change in agriculture. More specifically, I consider how subsidies affect functioning of input and output markets, and the selection of business strategies within them. The main hypothesis is that subsidies affect these markets differently, and that allows rent-seeking that hinders the overall productivity of the sector. I apply a replicator dynamics model for the task. I test my hypothesis with the EU’s 2003 CAP reform. The data is comprehensive microdata of Finnish grain and oilseed farms for years the 2004–2013. In order to examine distributional level shifts, I use quantile regression techniques. I find that the policy incentives have directed sectoral change more strongly than market incentives and have thus significantly affected production decisions. The subsidies have also attenuated the market signals and therefore increased sectoral inefficiency. The reform that aimed to improve market orientation has had little effect. The reform has affected structural change in input and output markets differently. While land use adjustment has become more rigid for all the farms, especially the more market oriented ones have been able to exploit increased output market flexibility. However, the negative effects are more prominent in total and the net effect of the reform was negative. 相似文献
