This paper considers factor estimation from heterogeneous data, where some of the variables—the relevant ones—are informative for estimating the factors, and others—the irrelevant ones—are not. We estimate the factor model within a Bayesian framework, specifying a sparse prior distribution for the factor loadings. Based on identified posterior factor loading estimates, we provide alternative methods to identify relevant and irrelevant variables. Simulations show that both types of variables are identified quite accurately. Empirical estimates for a large multi‐country GDP dataset and a disaggregated inflation dataset for the USA show that a considerable share of variables is irrelevant for factor estimation. 相似文献

管理者必须克服坏的行为,不能抱怨、哭诉,或者责怪其他人。把员工带出短期的失败阶段需要强大的领导力。否则,坏的行为会使短期的失败阶段更加糟糕。 相似文献

This article identifies an integrated teaching strategy that was originally developed for engineers, the so-called ‘micro-insertion’ approach, as a practical and effective means to teach ethics at business schools. It is argued that instructors can incorporate not only generic or thematic learning objectives for students into this method (i.e., the intended content of what is being taught: in our case, an underlying ethical base for doing business), but also do so via a strategically integrated approach regarding the appropriate mix and timing of these micro-insertions. With this in mind, we propose a qualitative and example-based approach that endeavors to provide a versatile way for business teachers to incorporate ethics into their general business classes. We also present a conceptual and theoretical framework that underpins this method, and we further provide a set of specific examples and a practical table that show how business instructors might integrate ethics-oriented micro-insertions into their teaching. 相似文献

Current evidence on philanthropic giving to nonprofit organizations (NPOs) suggests that NPOs are not successfully cultivating relationships with prospective donors in the millennial generation; this has negative implications for the organizations' future financial sustainability. The current investigation employed a framework grounded in relationship management theory to explore how NPOs can better engage with this target audience. A series of focus groups revealed nuanced factors that facilitated relationship-building between millennials and NPOs, rooted in the theoretical constructs of trust and openness. These results can be used to guide NPOs' donor-engagement strategies focused specifically on millennials, thus guiding long-term donor relations efforts. 相似文献

This research aims to examine the daily return generating processes for country-specific funds in five east-Asian countries for the period 1995-2000. The effects of component returns and their volatility on the dollar denominated returns and volatility of U.S., international investors and the effects of exchange rate regimes on risk and return are also evaluated. The GARCH-M model is adopted, without the restrictive assumptions of linearity, independence, and constant conditional variance. The time frame, 1995-2000 captures a 30 months period prior to these East Asian countries aborting exchange rate stabilization/intermediate exchange rate regimes in response to the currency crisis. The decomposition of returns to holders of country-specific equity funds into the component returns due to changes in the exchange rate and the returns valued in the fund's foreign currency during a period of crisis provides additional information. This research provides evidence of the importance of examining component returns. With regards to the effects on volatility, both the conditional variances associated with the exchange rate returns and the returns denominated in the foreign currencies show some importance, especially the conditional variances associated with the returns denominated in the foreign currencies. With regards to the effects of return component, the exchange rate returns have a greater effect on the fund returns than foreign currency dominated returns. 相似文献

A current challenge for non-profit organizations (NPOs) is attracting and retaining a new generation of younger philanthropic donors. As such, this exploratory focus group study examined how donor-perceived barriers and motivators may inform NPOs' understanding of strategically approaching and motivating Generation Z (Gen Z; born 1996–2012) donations. More specifically, the findings revealed that the participants (1) experienced pseudoinefficacy as they felt their small donations would not make a difference. In addition, they felt (2) a general lack of trust toward NPOs regarding financial stewardship. Finally, (3) they wanted organizations to develop data-driven narratives to share how funds were used to help the community. As such, the analysis and recommendations are rooted in Narrative Theory. Narrative strategies present a potential avenue for generating persuasion and fostering positive relationships between NPOs and emerging Gen Z donors. 相似文献

We discover a consumption channel of monetary policy in a model with money and government bonds. When the central bank withdraws government bonds (short‐term or long‐term) through open market operations, it lowers returns on bonds. The lower return has a direct negative impact on consumption by households that hold bonds and an indirect negative impact on consumption by households that hold money. As a result, firms earn less profits from production, which leads to higher unemployment. The existence of such a consumption channel can help us understand the effects of unconventional monetary policy. 相似文献

A burgeoning literature looks into the processes and actors involved in the adoption and emulation of best practices and models of urban policy and development across the globe, often with the aim of attracting investment and making cities more competitive. With its focus on leisure, tourism and global capital, the redevelopment of the Bay of Luanda, in the capital of Angola, echoes the rhetoric, policies and projects underpinning such practices. Yet, a deeper interrogation reveals that the redevelopment forms part of a predominantly inward‐looking project driven by the highest echelons of the national government and its ruling party. While these actors mimic and appropriate the language and tools of entrepreneurial cities, their aim is not necessarily to make the city more internationally competitive but to achieve domestic political legitimacy and stability. The argument presented in this article builds on McCann's ( 2013 ) call for scholars to also consider the ‘introspective’ politics of urban policy boosterism from the perspective of a context in which power is highly centralized. The article thus contributes to a growing literature that advances more adequate and provincialized theorizations of urban policy and city governance in the global South, with a particular focus on the African context. 相似文献
