The twenty-first century has seen an increase in ethical misconduct at the workplace, highlighting the need to stimulate discussion on the role of work ethics. The objective of the current study is to extend the literature on work ethics by examining the role of Islamic work ethic in enhancing the task performance of employees. The current study proposes that psychological capital mediates the relationship between Islamic work ethic and task performance. It is also proposed that ethical leadership might act as a boundary condition that boosts the positive relationship between Islamic work ethic and psychological capital. Data were collected in three-time lags from employees working in the service sector of Pakistan (N?=?218) through the questionnaire. The results supported the mediation and moderation hypothesis, confirming that psychological capital mediates the relationship between Islamic work ethic and task performance. Ethical leadership moderates the relationship between Islamic work ethic and psychological capital. The results offer implications for theory and practice. Limitations and future research directions are also discussed.
The study examines and highlights the impact of selected foreign inflows (aid, trade, FDI, debt and remittances) on the economic growth of the South Asian Association for Regional Cooperation (SAARC) countries. The existent literature lacks a comprehensive analysis of the SAARC countries as countries like Afghanistan, Bhutan and the Maldives have largely been ignored due to the shorter time periods of available data. The study is empirical in nature and utilizes panel data techniques on macroeconomic data for the period 2008–2015. Foreign aid and foreign direct investment are found to impact economic growth positively. Foreign debt and trade flows are found to adversely affect economic growth. No relationship is established between the flow of remittances and the economic growth of these countries. The obtained results are robust to different proxy variables and the addition of macroeconomic variables. For the first time, the study provides policy implications based on the data of all SAARC countries. The study recommends focusing on increasing the inflows of resources in the form of aid and foreign direct investment (FDI) from the developed world to achieve higher economic growth. 相似文献

The bid-ask spread of stock prices is examined for a sample of dividend initiating firms. The average percentage and dollar bid-ask spreads increase significantly on the day preceding the Wall Street Journal Index announcement date, possibly reflecting, on average, the market maker's anticipatory uncertainty. The day -1 increase in spread is inversely associated with firm size, an information environment proxy, after considering the simultaneous effects of dividend yield, returns variance, dollar trading volume and share price. The average percentage spread declines significantly on day 0 from its day -1 level and remains lower, on average, over a 365 day post-announcement period than 90 day pre-announcement levels. Similar results are obtained for dollar spread averages. The post-announcement percentage spread decline suggests a resolution of uncertainty, and is positively associated with the dividend yield. Dividend initiation announcements appear to reduce informational asymmetry. 相似文献
Islamic financial institutions are being pressurized by critics to offer profit and loss sharing (PLS) financing, such as venture capital (VC) financing, for the purpose of entrepreneurial development aligned to the principle of equity risk sharing. Our study aims to link PLS investments with portfolio optimization opportunities for the Islamic asset managers. Using portfolio analysis with dynamic conditional correlation, Markov switching, and maximal overlap discrete wavelet transformation, our findings tend to indicate that there is indeed a portfolio optimization opportunity in investment universe for the fund managers who invested in PLS investments in the context of VC asset class over the long run. 相似文献
This article provides a fresh insight into the dynamic nexus between oil prices, the Saudi/US dollar exchange rate, inflation, and output growth rate in Saudi Arabia’ economy, using novel Morlet’ wavelet methods. Specifically, it implements various tools of methodology: the continuous wavelet power spectrum, the cross-wavelet power spectrum, the wavelet coherency, the multiple and the partial wavelet coherence to the annual sample period 1969–2014. Our results unveil that the relationships among the variables evolve through time and frequency. From the time-domain view, we show strong but non-homogenous linkages between the four variables. From the frequency-domain view, we uncover significant wavelet coherences and strong lead-lag relationships. From an economic view, the wavelet analysis shows that Saudi economy is still exposed to several global risk factors, which are mainly related to the oil market volatility, and the pegging of the local currency to the US dollar. Such risk factors strongly and negatively affect the real economic growth, exert more pressure on inflation, and substantially limit the freedom to pursue an independent monetary policy. 相似文献
In this article, we consider the recent increase in inequality in Indonesia. We make new, consistent estimates of expenditure inequality for 1993–2013, using several measures that draw on household expenditure data from the National Socioeconomic Survey (Susenas) for 1993–2013. In doing so, we note that the central statistics agency, Badan Pusat Statistik (BPS), used grouped data for its estimates of inequality until 2009 and that this underestimated inequality up to then. Thus the rise in inequality reported since 2009 actually has a longer history. We argue that Indonesia experienced divergence and convergence at the same time: the magnitude of the rise in inequality was significant (divergence), but the rise was greatest in provinces or districts with low initial levels of inequality (convergence). We consider the literature on drivers of changes in inequality and identify a set of hypotheses, with an empirical basis, which we introduce as potential Indonesian-specific drivers of rising inequality for future exploration. 相似文献
