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

After‐tax income inequality has risen since the mid‐1990s, as increases in market income inequality have not been offset by greater fiscal redistribution. We argue that the substantial increase in the diversity of consumer goods has mitigated mounting political pressures for redistribution. Within a probabilistic voting framework, we demonstrate that if the share of diversified goods in the consumption bundle increases sufficiently with income, then an increase in goods diversity can reduce the political equilibrium tax rate. Focusing on OECD countries, we find empirical support for both the model's micro‐political foundations and the implied relation between goods diversity and fiscal policy outcomes.  相似文献

Critics of Pope Francis’s Evangelii gaudium argue that recent economic growth and reductions in inequality are evidence that his notion of the “economy of exclusion” is misguided. However, Francis alludes to another type of exclusion—increased uncertainty generated by technological change that affects citizens even in developed nations. Drawing from Post‐Keynesian institutionalist theory, this article argues that this condition is common in capitalism, and that grassroots reforms are needed to ensure shared prosperity.  相似文献

Artificial intelligence is revolutionizing the way we do business. Whereas both the adoption of technological innovations and strategic decision making have been subject to prior research, this experimental study is first to combine both. To understand the impact of choice complexity and cognitive perceptions on the willingness to delegate a strategic decision to an algorithm, we conducted an experiment with 310 participants. We find that although choice complexity has no effect, participants with low levels of situational awareness are more likely to delegate. The findings augment research on choice complexity in decision making by emphasizing the relevance of cognitive perceptions.  相似文献

Using daily lottery data from Washington State by zip code from January 2011 through mid‐March 2016, we estimate that Powerball income elasticities range from ?0.16 to 0.16 as the Powerball jackpot increases from its minimum to $1.5 billion, while Mega Millions income elasticities range from ?0.08 to 0.03 as the Mega Millions jackpot increases from its minimum to $640 million. Controlling for jackpot size, each of three major game changes during this time period has a significant effect on own‐game and cross‐game sales. Despite these significant game changes, however, these lotto games are a highly regressive source of revenue for Washington State. (JEL H22, H71, L83)  相似文献

Many women interact with the South African social security system in relation to the Child Support Grant (CSG), which is social assistance payable for children living with low-income caregivers. This paper explores women's accounts of how the CSG serves to protect and respect dignity, a foundational value in the South African Constitution. Drawing from focus groups and in-depth interviews with female CSG recipients of working age, it is argued that whilst the experience of using the CSG does protect dignity in certain important respects, other aspects including the application process, the small amount of the grant and negative discourses associated with the status of being a CSG recipient were experienced by many as erosive of dignity.  相似文献

Agricultural policies in sub-Saharan Africa have paid insufficient attention to sustainable intensification. In Uganda, agricultural productivity has stagnated with aggregate increases in crop production being attributed to expansion of cultivated land area. To enhance sustainable crop intensification, the Ugandan Government collaborated with stakeholders to develop agricultural policies using an evidence-based approach. Previously, evidence-based decision-making tended to focus on the evidence base rather than evidence and its interactions within the broader policy context. We identify opportunities and pitfalls to strengthen science engagement in agricultural policy design by analysing the types of evidence required, and how it was shared and used during policy development. Qualitative tools captured stakeholders' perspectives of agricultural policies and their status in the policy cycle. Subsequent multi-level studies identified crop growth constraints and quantified yield gaps which were used to compute the economic analyses of policy options that subsequently contributed to sub-national program planning. The study identified a need to generate relevant evidence within a short time 'window' to influence policy design, power influence by different stakeholders and quality of stakeholder interaction. Opportunities for evidence integration surfaced at random phases of policy development due to researchers’ ’embededness’ within co-management and coordination structures.  相似文献

We develop a theory of incentives, wages, and employment in the context of team production. A central insight is that specialization and division of labor not only improve productivity but also increase effort and the sensitivity of effort to incentives under moral hazard. We show that employment and incentives are complements for the principal when the positive effects of specialization and division of labor outweigh the increase in risk associated with additional employment and are substitutes otherwise. We provide new characterizations of the partnership, the firm, and the role of the budget‐breaker that are quite different from the classical literature.  相似文献

Innovation offshoring (IO) has become a widespread management practice. Yet, evidence on the performance implications is inconsistent, and scattered across disciplines and contexts. We argue that the benefits firms can derive from IO depend on the institutional environment at home. Drawing on recent work on institutional theory in international business, we explore institutions that facilitate reverse knowledge transfer and/or institutional arbitrage with respect to innovation‐related activities. The results of our meta‐analysis that synthesizes evidence from 48 samples show that IO is related positively to innovation performance. As predicted, this relationship is moderated by differences in the institutional environments across countries. Specifically, when national innovation systems are weak at home, IO appears to enable institutional arbitrage strategy whereas Confucian cultures enable more effective reverse knowledge transfer. However, contrary to our expectations, the beneficial effects of IO appear to have diminished over time.  相似文献
