We examine the effect of domestic violence on child mortality using Demographic and Health Surveys from thirty-two developing countries. We first examine conditional associations between violence faced by the mother and child mortality after controlling for observable confounders. Children of (ever) physically victimized mothers are 0.4, 0.7, and 1.0 pp more likely to die within thirty days, a year, and five years of being born. We find similar associations when examining violence experienced in the last twelve months, although these are no longer statistically significant. The association is statistically significant, and larger, if the mother experiences violence in the last twelve months often, rather than sometimes. Violence is significantly associated with pregnancy loss, suggesting the true effect on mortality is larger than estimates based on live-births would suggest. We investigate robustness of associations to omitted variable bias, assessing the role of selection on unobservables to estimate lower bounds on the true effect. These continue to indicate economically meaningful positive effects, suggesting selection on unobservables would need to be 2.4–3 times that of selection on observables to nullify the estimated effect. We provide evidence that maternal smoking and breastfeeding practices are mediators in the relationship between domestic violence and child mortality. 相似文献

This paper tests whether housing prices in the five segments of the South African housing market, namely large-middle, medium-middle, small-middle, luxury and affordable, exhibit non-linearity based on smooth transition autoregressive (STAR) models estimated using quarterly data from 1970:Q2 to 2009:Q3. Findings point to an overwhelming evidence of non-linearity in these five segments based on in-sample evaluation of the linear and non-linear models. We next provide further support for non-linearity by comparing one- to four-quarters-ahead out-of-sample forecasts of the non-linear time series model with those of the classical and Bayesian versions of the linear autoregressive (AR) models for each of these segments, for the out-of-sample horizon 2001:Q1 to 2009:Q3, using the in-sample period 1970:Q2 to 2000:Q4. Our results indicate that barring the one-, two and four-step(s)-ahead forecasts of the small segment, the non-linear model always outperforms the linear models. In addition, given the existence of strong causal relationship amongst the house prices of the five segments, the multivariate versions of the linear (classical and Bayesian) and STAR (MSTAR) models were also estimated. The MSTAR always outperformed the best performing univariate and multivariate linear models. Thus, our results highlight the importance of accounting for non-linearity, as well as the possible interrelationship amongst the variables under consideration, especially for forecasting. 相似文献

BOARD COMPOSITION FROM A STRATEGIC CONTINGENCY PERSPECTIVE 总被引:15,自引:0,他引:15
This study examined the association between corporations’environments, strategies, and past performance and the composition of their boards of directors as measured by size and outside director representation. The environment, strategy and past performance were viewed as posing a strategic contingency; each of these sets could determine the success or failure of the company. Data on 119 Fortune 500 industrial companies for the 1983-9 period were used. Canonical analysis showed that increased uncertainty of a firm's environment, use of external growth and diversification; reliance on leverage as a means of finance, and poor past financial performance were associated with large board size and increased outside representation in subsequent years. Most important, board composition was positively associated with future measurements of corporate financial performance. 相似文献

This study examined the impact of job analysis on organizational performance among 148 companies based in the United Arab Emirates (UAE), a Gulf-region country. Survey results indicated that a practice of proactive job analysis was strongly related to organizational performance. This relationship was strongest to the extent that companies maintained HR information systems, accorded HR greater involvement in strategic planning and emphasized competency-based characteristics of employees in the job analysis approaches they used. The findings suggest that a company-wide policy of job analysis is an important source of competitive advantage in its own right, and merits due attention of HR professionals, line managers and top management. The study extends the findings of the HR–performance research pursued in Western countries to a non-Western context. 相似文献

A typology of the relative powers of the chief executive officer and the board of directors was derived based on the literature, highlighting four situations: Caretaker, Statutory, Proactive and Participative boards. Data collected from Fortune 500 Industrial and Fortune 500 Service corporations supported the typology. The results showed significant differences among the four board types in their characteristics, internal process, decision-making styles, board effectiveness, and contribution to company performance. Powerful boards were associated with superior corporate financial performance. 相似文献

ABSTRACT By building on a knowledge‐based view of the firm, this paper addresses a relatively unexplored area of roles and dynamics of corporate governance in younger, threshold firms that are undergoing a transition from the emergence to the professional management stage. Our analysis is focused on the process of capability development, exploring the effect of the asymmetry in knowledge that often exists between directors and senior managers on the governance of threshold firms. We examine the key sources of this asymmetry, explore ways directors and senior executives learn, and then discuss the implications of this learning on the evolution of governance systems in the threshold firm. 相似文献

abstract The emergent literature on dynamic capabilities and their role in value creation is riddled with inconsistencies, overlapping definitions, and outright contradictions. Yet, the theoretical and practical importance of developing and applying dynamic capabilities to sustain a firm's competitive advantage in complex and volatile external environments has catapulted this issue to the forefront of the research agendas of many scholars. In this paper, we offer a definition of dynamic capabilities, separating them from substantive capabilities as well as from their antecedents and consequences. We also present a set of propositions that outline (1) how substantive capabilities and dynamic capabilities are related to one another, (2) how this relationship is moderated by organizational knowledge and skills, (3) how organizational age affects the speed of utilization of dynamic capabilities and the learning mode used in organizational change, and (4) how organizational knowledge and market dynamism affect the likely value of dynamic capabilities. Our discussion and model help to delineate key differences in the dynamic capabilities that new ventures and established companies have, revealing a key source of strategic heterogeneity between these firms. 相似文献

Theory development and testing are central to the advancement of entrepreneurship as a scholarly field. For nearly three decades now, researchers have borrowed popular theories from other disciplines and adapted them to the study of diverse entrepreneurship phenomena. This has enhanced the rigor of research findings. Future studies can achieve greater rigor and relevance by paying more attention to the context of their investigations. Understanding the nature, dynamics, uniqueness and limitations of this context can enrich future studies. This article describes common problems revealed in recent entrepreneurship research when applying existing and new theories to well known vs. emerging and novel phenomena. The article also suggests strategies to enrich creative and constructive theory building. 相似文献

In this paper, three major themes in research on corporate social responsibility (CSR) are identified. Of particular interest, however, is the potential link between CSR and organizational effectiveness (OE). Data collected from 410 college graduate and undergraduate students were used to examine this relationship. Using factor analysis, eight dimensions of CSR and three components of OE were extracted. Canonical analysis was then performed. The result supports the proposition that specific CSR practices affect select OE outcomes. In addition, the method employed here provides a parsimonious approach to give priority to social claims.Shaker A.

A model of correlates of executives' views of organizational politics was presented. The model incorporated three sets of variables: executives' background, values and attitudes. Data collected from 302 managers were used to validate the model. The results showed that precursors of executive perceptions of the ethics and effect of company politics were different. Values were stronger than background variables in explaining executives' views of company politics.Dr. Shaker A.
