Family involvement in business creates idiosyncrasies in firm behavior that promote long‐term, often transgenerational, strategic logics that ostensibly align with the motivations and outcomes of corporate entrepreneurship. Interestingly, extant research provides only minimal insight into the heterogeneous nature of corporate entrepreneurship orientations pursued by family firms. To better understand this heterogeneity, we develop a typology of corporate entrepreneurship in family firms providing a reconciliatory approach to this literary diversity and suggest that the varied corporate entrepreneurship orientations of family firms are impacted by the duality of a family's distinct intention to pursue transgenerational succession and capabilities to acquire external knowledge.  相似文献

Work‐family boundary research debates whether family demands should be integrated or separated from work demands. Our thesis is that the impact of boundary management preferences on business performance depends on the entrepreneur's gender. We also investigate how family‐to‐business support and business location alter the gender and boundary management preference interaction. Results show that an integration preference enhances business performance for men regardless of family‐to‐business support or business location. A segmentation preference aids women's business performance, especially among those with high family‐to‐business support and an independent business. An integration preference yields greater business performance for women with an at‐home business.  相似文献

We examine the impact of innovation disclosure through patenting on firms' cost of debt, focusing on the American Inventors Protection Act (AIPA) as an exogenous shock in innovation disclosure regulation. Post‐AIPA, firms have an incentive to apply for patents only if commercial success is likely. Accordingly, we expect post‐AIPA patents to be a better proxy for successful innovation activity, and thus to have a stronger effect on reducing the cost of debt than pre‐AIPA patents. Indeed, we find that pre‐AIPA patents reduce the cost of debt only for the most innovative firms, while post‐AIPA, this effect holds for all firms.  相似文献

Over a 50 year period, Australian Rules football's major league, the Victorian Football League, did not always use its largest and best-equipped stadium for regular season games between its most popular teams or schedule those teams to play twice in a regular season. We calculate deadweight losses from the use of capital goods (stadiums) and effects of match scheduling in this professional sports league. Such analysis has not been attempted previously because of the absence of a counterfactual. The welfare losses were significant but not sufficient to threaten the survival of a distance-protected cartel.  相似文献

Conflict between favorites and underdogs is an everyday phenomenon. Research suggests that people support the underdog as they see a reflection of their own self in the person at a disadvantaged position. Two studies examine the effect of underdog brand biography in two different contexts. Study 1 provides support for the notion that underdog brand biographies for established brands elicit stronger consumer response than underdog brand biography for new brands. In study 2, a 2 × 2 between-subjects experimental design measured respondents’ reaction toward an underdog brand biography over a top dog brand biography under conditions of public versus private consumption. Results demonstrate that consumers exposed to underdog brand biographies in the private consumption condition will be more likely to respond favorably than when they are exposed to the public consumption condition. Based on the results it is suggested that advertisers make use of underdog brand biographies in case of established brands. Furthermore, choice of underdog brand narratives is likely to bring positive results under conditions of private consumption.  相似文献

The electric bike (e-bike) is emerging as a new sustainable transport mode in Norway and has the potential to lead to increased cycling among the population. However, little is known about psychosocial determinants of e-bike use. The aim of the study was to examine the role of normative and environmental beliefs, the perceived attributes of e-bikes, and innovativeness and demographical factors related to e-bike use in a Norwegian sample. An online survey was used to collect data from 910 respondents, including both e-bike users (252) and non-users (658). The respondents were recruited via a commercial panel (response rate 42.04%) and a Facebook post. A structural equation modeling analysis was used to analyze the data. The structural model had a good fit to the data. The results showed that attitudes towards e-bike use followed by innovativeness were the most important predictors of e-bike use. The normative processes measured within the Norm Activation Model activated positive attitudes towards e-bike use, which in turn predicted e-bike use. There was a negative relationship between e-bike and conventional bike use, while a positive relationship was found between car and e-bike use. The results are discussed with regard to their implications for interventions aiming to promote e-bike use.  相似文献

The unexpected introduction and spread of COVID-19 has presented significant challenges for every aspect of Canadian society. Although the food and agricultural sector is positioned better than most, there are many risks that will need to be managed in the coming months. The suite of Federal-Provincial-Territorial Business Risk Management (BRM) programs delivered under the Canadian Agricultural Policy framework are meant to assist farmers in managing risks; however, there are no corresponding specialized programs for agribusinesses. The underlying structure of the BRM program was developed decades ago and certainly not with any thought to the possibility of a global pandemic. This article considers to what extent the BRM program and, more broadly, government programming will assist farmers in managing new risks. By default, the article is speculative in nature given that we are currently at the onset of the pandemic in Canada.  相似文献

This paper re-examines the stochastic properties of U.S. state real per capita personal income, using new panel unit-root procedures. The new developments incorporate non-linearity, asymmetry, and cross-sectional correlation within panel-data estimation. Including nonlinearity and asymmetry finds that 43 states exhibit stationary real per capita personal income whereas including only nonlinearity produces 42 states that exhibit stationarity. Stated differently, we find that two states exhibit nonstationary real per capita personal income when considering nonlinearity, asymmetry, and cross-sectional dependence.  相似文献

Using a sample splitting approach that does not impose an exogenous quadratic term, we examine the effect of financial development on economic growth in sub-Saharan Africa by allowing the link to be mediated by the level of institutions. Our findings reveal a disproportionate growth-enhancing effect of finance, given countries’ distinct level of institutional quality. More specifically, when the International Country Risk Guide-based measure of institutions is used as the threshold variable, below the optimal level of institutional quality, financial development does not significantly promote economic growth. For countries with institutional quality above the threshold, higher finance is associated with growth. However, when institutions are measured by World Governance Indicators proxy, we find a significant effect of financial development, irrespective of whether a country is below or above the threshold. Interestingly, the growth-enhancing effect of finance is greater for low-institution countries relative to high-institution countries. Thus, through its ability to provide some crucial roles, the well-developed financial sector may also perform the function of sound institutions in influencing economic growth.  相似文献
