Control groups can provide counterfactual evidence for assessing the impact of an event or policy change on a target variable. We argue that fitting a multivariate time series model offers potential gains over a direct comparison between the target and a weighted average of controls. More importantly, it highlights the assumptions underlying methods such as difference in differences and synthetic control, suggesting ways to test these assumptions. Gains from simple and transparent time series models are analysed using examples from the literature, including the California smoking law of 1989 and German reunification. We argue that selecting controls using a time series strategy is preferable to existing data‐driven regression methods.  相似文献

Which factors facilitate the identification of business opportunities for sustainable development? To answer this question, we develop a process model of sustainable opportunity identification. We argue that sustainable opportunity identification is a process with transitions from problem to solution identification and from solution to sustainable opportunity identification. Moreover, the transitions are facilitated by two factors—awareness of adverse consequences and entrepreneurial attitude—providing motivation and direction in the process. We tested our model in a field study (N = 107) and two experiments (N = 53 and N = 69). Our findings show that awareness of adverse consequences and entrepreneurial attitude influence the process of sustainable opportunity identification, explaining under which conditions people are more likely to identify business opportunities for sustainable development. Our study thus contributes to the field of sustainable entrepreneurship.  相似文献

The EU and the African, Caribbean and Pacific countries (ACP) are presently renegotiating their trade relations. Behind these negotiations are the fundamental conflict between the existing arrangement and multilateral trade rules, the frustration regarding poor ACP trade performance, the ineffectiveness of trade and trade-related ACP policies, and the inefficiency of corresponding EU assistance. This article highlights the fundamentals of the envisaged Economic Partnership Agreements (EPAs) between the EU and the ACP countries, sums up previous estimates of their probable economic impact, discusses policy options for ACP countries and sheds light on basic prerequisites, particularly on institutional conditions, that should be fulfilled to ensure the success of EPAs.  相似文献

In the past, the protection of agriculture in the EU from exchange rate instability was accomplished at the cost of confusing regulations, welfare losses and the discrimination of other sectors. Will the 1993 reform of the Agri-Monetary System, combined with wide 15% European Monetary System margins and the recent GATT agreement, lead to more efficiency in European agriculture?  相似文献

While there are strong equity and efficiency reasons for subsidizing education in developing countries, the prevailing dominance of governments in the financing and provision of educational services can be questioned. There is some evidence supporting the conclusion that a partial cost recovery through user fees may reduce the rationing of services which is still a pressing problem in many low-income countries, and that private providers tend to be more cost-efficient than their public counterparts.  相似文献

We propose a model for the learning process in technology entrepreneurship based on the findings from an in‐depth case study of an engineering degree that emphasizes technology entrepreneurship. Taking learning paradigms from entrepreneurship education into account, we specify the links between pedagogical approaches, activities, and learning contexts and specific technology entrepreneurship learning outcomes. For example, we examine how the use of existential learning with self‐directed activities in real‐world contexts contributes to achieving high‐level entrepreneurial competencies such as the ability to critically self‐reflect on the choices made by the technology‐based venture. As such, we contribute to the definition of teaching models for technology entrepreneurship education.  相似文献

We investigate when organizational justice matters to employees’ commitment in the postacquisition process after a company is taken over in a cross‐border acquisition. Overwhelming evidence from the literature suggests that employees who are treated fairly during acquisitions are more committed to their new firms. We extend this finding by dividing organizational justice into three subdimensions: informational justice, interpersonal justice, and procedural justice. We find evidence that procedural justice is an important antecedent of affective merger commitment at an early stage of the integration period, while informational justice becomes important at a later stage. Further analysis on heterogeneity between the target firm's employees and the bidder firm's employees reveals that, immediately after the acquisition, target firm's employees value knowing where they will be at the new firm (procedural justice), while bidder firm employees are more concerned about communication and transparency (informational justice). Our results point to the importance of organizational justice in a cross‐border merger and acquisition (M&A) setting and the need for a separate study of issues related to bidder firms and target firms. © 2016 Wiley Periodicals, Inc.  相似文献

Family firms commonly prefer internal funding and retention of control. Under certain circumstances, however, equity investments from outside the family can be a relevant alternative source of capital. To facilitate further knowledge about the interaction of family-owned businesses and external equity investors, the present work reviews 42 studies and suggests possible directions for future research. Results reveal that extant studies focus mainly on five key areas—corporate finance, contract design and collaboration, succession and exit route, strategy and performance, and corporate governance. Moreover, the paper discusses various gaps in the extant work and presents three opportunities for future research in a detailed manner. These include a comparison of different types of investors in the context of family-owned businesses, an investigation of minority investor exits from family firms, and an analysis of the impact of investors on family firm boards. All in all, the findings can guide the future development of this emerging field of research and have implications for theory and practice.  相似文献
