Demands for the imposition of economic sanctions under UN auspices on South Africa have been voiced for quite some time. Rhodesia was the first country ever to be subjected to a full obligatory embargo by the UN Security Council. An analysis of the embargo against Rhodesia will therefore help to answer the question whether an embargo on South Africa stands a chance of success. 相似文献

In this paper, we consider the case of finite time dimension in the panel stationarity tests with structural breaks. By fixing T, the finite sample properties of the tests for both micro (T small and N large) and macro (both T and N large) panel data are generally greatly improved. More importantly, the derivation of the tests for finite T and , as opposed to joint asymptotic where N and simultaneously, avoids the imposition of the rate condition making the test valid for any (T, N) blend. Four models corresponding to the usual combination of breaks are considered. The asymptotic distributions of the test are derived under the null hypothesis and are shown to be normally distributed. Their moments for T fixed are derived analytically employing Ghazal’s corollary 1. The case with unknown breaks is also considered. The proposed tests have generally empirical sizes that are very close to the nominal size. The Monte Carlo simulations show that the power of the test statistics increases substantially with N and T. 相似文献

In this paper we develop an open economy model explaining the joint determination of output, inflation, interest rates, unemployment and the exchange rate in a multi-country framework. Our model—the Halle Economic Projection Model (HEPM)—is closely related to studies published by Carabenciov et al. (2008a,b,c). Our main contribution is that we model the Euro area countries separately. In doing so, we consider Germany, France, and Italy which represent together about 70% of Euro area GDP. The model combines core equations of the New-Keynesian standard DSGE model with empirically useful ad-hoc equations. We estimate this model using Bayesian techniques and evaluate the forecasting properties. Additionally, we provide an impulse response analysis and historical shock decomposition. 相似文献

In this article, we hypothesize that leaders who display group-oriented values (i.e., values that focus on the welfare of
the group rather than on the self-interest of the leader) will be evaluated more positively by their followers than leaders
who do not display group-oriented values. Importantly, we expected these effects to be more pronounced for leaders who are
ingroup members (i.e., stemming from the same social group as their followers) than for leaders who are outgroup members (i.e.,
leaders stemming from a different social group than their followers). We tested our hypotheses in two studies. Results of
a field study (N = 95) showed the expected relationship between leaders’ group-oriented values and followers’ identification with their leaders.
A scenario study (N = 137) replicated the results and extended it to followers’ endorsement of their leaders. Overall, these findings suggest
that displaying group-oriented values pays off more for ingroup than for outgroup leaders. 相似文献

Although researchers and practitioners increasingly focus on health promotion in organizations, research has been mainly fragmented and fails to integrate different organizational levels in terms of their effects on employee health. Drawing on organizational climate and social identity research, we present a cascading model of organizational health climate and demonstrate how and when leaders' perceptions of organizational health climate are linked to employee well-being. We tested our model in two multisource studies (NStudy 1 = 65 leaders and 291 employees; NStudy 2 = 401 leader–employee dyads). Results showed that leaders' perceptions of organizational health climate were positively related to their health mindsets (i.e., their health awareness). These in turn were positively associated with their health-promoting leadership behavior, which ultimately went along with better employee well-being. Additionally, in Study 1, the relationship between perceived organizational health climate and leaders' health mindsets was moderated by their organizational identification. High leader identification strengthened the relationship between perceived organizational health climate and leaders' health mindsets. These findings have important implications for theory and practice as they show how the dynamics of an organizational health climate can unfold in organizations and how it is related to employee well-being via the novel concept of health-promoting leadership. 相似文献
