Drawing on theories of perspective‐taking and i‐deals, this study explores the impact of supervisors' own caregiving responsibilities for elders and parental status on subordinates' schedule i‐deals. Moreover, we investigate the extent to which schedule i‐deals mediate the relationship between supervisors' caregiving responsibilities and two employee outcomes: satisfaction with work–family balance and turnover intentions. Using a sample of 520 dyads involving 137 supervisors and 520 employees, the results of multilevel analysis show that supervisors' caregiving responsibilities for elders is positively related to schedule i‐deals, but their parental status is not. The findings also show that schedule i‐deals mediate the effect of supervisors' caregiving responsibilities for elders on subordinates' satisfaction with work–family balance and turnover intentions. This research contributes to the i‐deals' literature by focusing on the role of managers' own caregiving responsibilities in facilitating the provision of schedule i‐deals to their subordinates and by exploring the consequences of schedule i‐deals to gain an understanding of the mutually beneficial nature of such deals. From a practical point of view, supervisors and HR departments might utilise schedule i‐deals to drive desirable employee outcomes, in particular their caregiving responsibilities, and to engender a family‐supportive organisational culture. 相似文献

This paper presents an experimental investigation of persuasion bias, a form of bounded rationality whereby agents communicating through a social network are unable to account for repetitions in the information they receive. We find that, after repeated communication within a social network, social influence depends not only on being listened to by many others, but also on listening to many others. We show that persuasion bias can be viewed as an extreme case of a generalized boundedly rational updating rule in which agents receive more or less attention depending on how many other agents they listen to. The results indicate that behavior in the experiment is consistent with an updating rule according to which agents' social influence is proportional to their indegree. 相似文献

We model agents’ preferences by cash-invariant concave functionals defined on L
∞, and formulate the optimal risk allocation problem as their infimal-convolution. We study the case of agents whose choice
functionals are law-invariant with respect to different probability measures and show how, in this case, the value function
preserves a desirable dual representation (equivalent to the Fatou property).

Estimation of Food Stamp Program (FSP) effects has been complicated by self-selection and by a contradiction between observed spending patterns and the economic theory of consumer choice. We developed a modified version of the traditional theory, in which participant households may be partly extramarginal even if they have some cash spending on at-home food. Using Current Population Survey (CPS) data for 2001–2005, we estimated Engel functions for at-home and away-from-home food spending for FSP participants and nonparticipants. Compared to nonparticipants with the same level of total income, participants had higher at-home food spending and lower away-from-home food spending. 相似文献

Hypothetical and actual cash willingness to pay (WTP) for an art print were elicited with dichotomous choice and open-ended question formats. Comparing hypothetical and actual dichotomous choice responses using both a likelihood ratio test and the method of convolutions suggests we reject equality at the 0.05 but not the 0.01 level. Hypothetical WTP was roughly two times actual WTP with the dichotomous choice format. There were no significant differences between the open-ended and dichotomous choice question formats when both were used to estimate hypothetical WTP or both used to estimate actual WTP. 相似文献

In this note, we analyze the local dynamics of a general non-linear fixedprice disequilibrium IS-LM model. We assume investment
behavior as a general nonlinear function avoiding any Kaldor type assumption. By proving the existence of a family of periodic
solutions bifurcating from a steady state, we confirm and extend some results in the literature for IS-LM models reducible
to Leinard’s equation. We use bifurcation theory and study the effect of a change of the adjustment parameter in the money
market upon the solutions of the model as the steady state loses stability.
We establish analytically that the values of the adjustment parameter in the money market may affect the equilibrium relative
to the product market and the government budget constraint. (JEL: C62, E32) 相似文献

Efficiency in wine grape production: comparing long‐established and newly developed regions of South Africa 下载免费PDF全文
Efficiency, partly based on technology, is central to international competitiveness. This article applies a stochastic frontier inefficiency model to a panel of 77 wine grape farms in South Africa between 2005 and 2015 and allows the comparison of efficiency levels for the old established wine regions with those of newer entrants. Thus, we investigate whether experience plus first choice of location matters more than the follower's advantage of newer technology. In all regions, a greater share of permanent labor and increased supervision raised efficiency, while more inorganic fertilizer and less irrigation has the opposite effect. Innovations in trellising had insignificant effects (except in the old regions) but not replacing old vines reduced efficiency. However, a higher proportion of red varietals also lowered efficiency in the old regions due to a fall in the price of red wine as these farmers continued to concentrate on quality reds. The new regions compensated for falling prices by increasing crop size with irrigation and fertilizer and extending the area planted, but with less concern for quality. This appears to be more successful in efficiency terms, but as international demand for quality wine increases it may be a poor long‐term strategy. 相似文献

In 2013 the minimum agricultural wage in South Africa was increased by an unprecedented 51%. We use data on 77 Western Cape Province wine grape farms from 2005–2015 to estimate the impacts on employment. Previous post‐apartheid labour market reforms increased minimum wages substantially, but re‐entry to global markets after sanctions were lifted increased demand and this preserved jobs in the wine sector. However, by 2005 this demand growth had largely ceased. The long‐run wage elasticity for permanent employees was found to be ?0.4, but for casual workers the figure was ?4.7, so the 51% wage increase is likely to decimate casual employment in the future. Thus, the poorest and most vulnerable casual workers lose most in terms of jobs, incomes and secure livelihoods, whereas 80% of full‐time staff benefit from the higher minimum wages. Thus, the minimum wage change is likely to increase the gap between privileged permanent staff and casual workers. This result is not surprising in view of the long‐standing interdependence between farmers and their permanent workers in wine grape production. 相似文献

This article explores the employability of information and communication technology (ICT) professionals from the perspective of small- and medium-sized enterprises (SMEs). The first stage of analysis, based on over 100 interviews with managers of ICT supplier companies in seven European countries (Germany, Greece, Italy, the Netherlands, Norway, Poland and the UK), showed most SMEs to have a generally ad hoc approach to managing the employability of their ICT professionals. Assessment and development plans were used primarily to keep skills current to business needs; however, the more developed northern European markets showed greater awareness of the ‘high commitment’ benefits of a more sophisticated approach towards career management (e.g. through mentoring or career planning). A second stage of analysis based only on UK interviews builds on this to propose a model of positive employer influence on psychological contracts through career and employability management practices. 相似文献

The study investigates the impact of adopting mechanized processing of cassava on farmers’ production efficiency in Uganda. A stochastic production function, using translog functional form, was used to compare efficiency measures of farmers in mechanized cassava-processing villages compared with the farmers in nonmechanized cassava-processing villages in 2014. Given the specification of the translog production function, the mean technical efficiencies of the farmers were 0.69 and 0.52 in mechanized and nonmechanized villages, respectively. The significant determinants of technical inefficiency among the respondents are farming experience, education, membership of farmer association, access to markets, sale of cassava to processors and farmers who planted cassava as sole crop are all negative, which confirm to a priori expectations and significant at different levels. The policy implication of the study is that mechanization of cassava processing, particularly if done at the right scale, could create demand that can transform primary production for increased yields, higher incomes and production efficiency of smallholder farmers who constitute a significant proportion of Uganda’s agricultural sector. 相似文献
