This paper advances the institutional entrepreneurial literature by exploring how, and when, the institutional entrepreneurial concepts embedded in theories of Reinventing Government and New Public Management are successful. Specifically, organizational level data from the nation’s oldest and largest urban school voucher programme are used to test how fundraising, reliance on government revenue, and membership in an umbrella organization impact different measures of performance. The analysis shows that organizations that fundraise, establish diverse revenue streams, and/or are members of established networks have certain performance advantages. The results are relevant to policymaker considering governance reforms premised on entrepreneurial activity.  相似文献

Participant-based sport events like ultramarathons are becoming increasingly popular but little is known about how they influence key stakeholders’ understandings of place and how these understandings fit into the tourism discourse on sustainability. The purpose of this study was, therefore, to gain insight into the sustainability of this type of active sport tourism event by examining the way that residents and visiting runners understand place (Grande Cache, Canada) in the context of the Canadian Death Race (CDR) ultramarathon. Interviews about place inclusive of a photo elicitation component were conducted with 15 residents and 20 visiting runners during the 2014 event. Thematic analysis resulted in the identification of four themes including: identity, dependence, physical setting, and social setting. Although they shared basic understandings of Grande Cache as a place of industry surrounded by nature, residents expressed stronger place identity than runners. Runners identified more with the activity of running but were connected to Grande Cache through place dependence and embodied experience. This discrepancy suggests that the sustainability of the CDR is at risk. Runners currently exhibit a high level of place dependence on Grande Cache, but a growing supply of race options poses a substitution threat.  相似文献

This paper examines the information content of the equity risk factors that explain cross variation of stock returns and predicting future macroeconomic growth. For the first time we incorporate a new foreign exchange risk factor, providing important insights into the relationship between risk factors and the business cycle. The methodology involves the performance of a stepwise regression analysis of future macroeconomic growth against the lagged returns of five risk factors (market risk premium, size, value, momentum and foreign exchange risk). The results are validated with Granger causality tests and out-of-sample dynamic forecasting. They show that the foreign exchange risk factor contains strong, stable and statistically significant incremental information concerning future macroeconomic growth. Firms that are sensitive to the foreign exchange risk thrive when an economic upturn is anticipated and firms that are insensitive to the foreign exchange risk will have larger returns when an economic downturn is anticipated.  相似文献

Patterns and drivers of post-socialist farmland abandonment in Western Ukraine   总被引:10,自引:0,他引:10  
Farmland abandonment restructures rural landscapes in many regions worldwide in response to gradual industrialization and urbanization. In contrast, the political breakdown in Eastern Europe and the former Soviet Union triggered rapid and widespread farmland abandonment, but the spatial patterns of abandonment and its drivers are not well understood. Our goal was to map post-socialist farmland abandonment in Western Ukraine using Landsat images from 1986 to 2008, and to identify spatial determinants of abandonment using a combination of best-subsets linear regression models and hierarchical partitioning. Our results suggest that farmland abandonment was widespread in the study region, with abandonment rates of up to 56%. In total, 6600 km2 (30%) of the farmland used during socialism was abandoned after 1991. Topography, soil type, and population variables were the most important predictors to explain substantial spatial variation in abandonment rates. However, many of our a priori hypotheses about the direction of variable influence were rejected. Most importantly, abandonment rates were higher in the plains and lower in marginal areas. The growing importance of subsistence farming in the transition period, as well as off-farm income and remittances likely explain these patterns. The breakdown of socialism appears to have resulted in fundamentally different abandonment patterns in the Western Ukraine, where abandonment was a result of the institutional and economic shock, compared to those in Europe's West, where abandonment resulted from long-term socio-economic transformation such as urbanization and industrialization.  相似文献

The empirical literature in economics and strategy on contract structure, including on franchise contract structure, has been largely based on agency and transaction cost theories. The effects of bargaining power have been much less studied. This paper considers the role of independent franchisee associations in franchising relationships as a means to test for the presence of bargaining power effects. We find that the presence or absence of a franchisee association is significantly related to each of three key contractual and relationship characteristics: contract duration, noncompete stringency, and terminations/nonrenewals. This suggests that bargaining power should be accounted for in studies of contract structure and relationship outcomes.  相似文献

The restricted maximum likelihood is preferred by many to the full maximum likelihood for estimation with variance component and other random coefficient models, because the variance estimator is unbiased. It is shown that this unbiasedness is accompanied in some balanced designs by an inflation of the mean squared error. An estimator of the cluster‐level variance that is uniformly more efficient than the full maximum likelihood is derived. Estimators of the variance ratio are also studied.  相似文献

This paper develops a model of cross-border M&A activity that features firm-level productivity shocks and endogenous export activity. We show that foreign firms will be relatively more attracted to targets in the domestic country that had high productivity levels that induced them to invest in large export networks several years prior to acquisition, but subsequently experienced a negative productivity shock (i.e., cherries for sale). From the theory we derive a dynamic panel binary choice empirical model to predict cross-border M&A activity, and find strong evidence for our hypotheses connecting the evolution of firm-level productivity to the ultimate targets of cross-border acquisitions using French firm-level data.  相似文献

Approximately 4.2 million Americans suffered nonfatal work-related injuries and 6,000 workers died of fatal work-related injuries in the US in 2005 (Bureau of Labor Statistics 2007 Bureau of Labor Statistics (2007), http://www.bls.gov/iif/home.htm (http://www.bls.gov/iif/home.htmo)  [Google Scholar]). Given these numbers, employee safety continues to be a concern in organizations despite engineering advances that have reduced exposures over the past few decades. Many factors contribute to workplace safety. These include characteristics of the physical environment and human behaviour within that environment. Human behaviour on some level plays a role in the vast majority of workplace accidents and injuries. This can include risky behaviour and signal detection failures, as well as a lack of proactive and collective safety behaviours that focus on changing the work environment to increase safety. Although several predictors of safety-related behaviour have been identified, there are some unresolved issues with respect to safety performance in organizations. This article focuses on the behaviours that compose safety performance, the factors that contribute to human safety performance, particularly those related to motivation, and some potential new areas of research in safety motivation in organizations.  相似文献

The primary objective of this article is to identify, given Internet accessibility, the factors that shape the decisions of individuals for personal Internet usage and its extent. Cross-sectional data from the European Social Survey database were utilized and an ordered probit model with selectivity was employed. The hypothesized link between the decision to use the Internet and the extent of usage was confirmed by the data. Household income, cost of access, demographics, media use, regional characteristics and general skill acquisition by individuals appear to correlate with Internet use and the extent of usage. In addition, a non-linear decomposition analysis was applied in order to identify the causes of the observed south/north divide. The results indicate that the observed differences in the probability of Internet use constitute a structural problem.  相似文献

A large number of studies have demonstrated that proximity effects from knowledge spillovers, network externalities and other forms of knowledge transfers among like firms are geographically bounded. However, only a few studies have measured the strength and geographic scope of such externalities and even fewer have done so for firms in very close proximity. In this study, we examine the size and geographic scope of proximity effects among all life science firms that have received Small Business Innovation Research (SBIR) grants in the US over a 23-year period while controlling for relevant regional and firm characteristics. From our empirical analysis, we conclude that proximity effects among nearby small life science firms are strong within one-tenth of a mile distance and are exhausted within a radius of 1.5 miles. By examining the location of all firms in the sample, we offer possible explanations for the narrow geographic scope of the measured proximity effects. We also explain the significance of such findings for academic research that seeks to understand the nature of spatial externalities and for public policy.  相似文献
