This article argues that there is a need to develop a ‘new’ economic and social history of the Middle East and North Africa (MENA) region that is based on exploiting novel sources of data, including (a) primary papyrological sources from the medieval period, (b) primary sources at the region's local archives and European (colonial) archives, and (c) primary sources from the ancient (pre-Islamic) period. The proposed ‘new’ history of the MENA region must be inter-disciplinary for two reasons: (a) digitizing and employing these novel data sources in research requires the collaboration of social scientists, historians, archaeologists, anthropologists, demographers and papyrologists, as well as the co-operation of MENA-based scholars who have better access to MENA's local archives, and (b) even if these novel sources are digitized, data limitations are likely to impose a constraint on the reach of quantitative analysis and thus necessitate an inter-disciplinary methodology that combines quantitative evidence with historical analysis.  相似文献

Multinational firms are increasingly sending their innovative tasks abroad. This article examines whether offshoring research and development, design, and engineering activities provides any gains in terms of firm‐level innovation output. The effects of trade in innovative tasks on the probability of firms being innovative and the share of innovative product sales in total turnover are examined using an instrumental variable approach. The data in use come from a recent survey, which provides cross‐section observations for more than 14,750 firms in seven European countries. The results suggest that those firms that offshore their innovative activities are 60% more likely to successfully innovate. Also, offshoring innovative activities increases the share of innovative product sales in total turnover up to 35%. Furthermore, firms in this sample appear to gain from trade in innovative tasks when such trade is in product innovation but not when such trade is in process innovation.  相似文献

Using data on corporate default experience in the U.S. and market rates of CDX index and tranche swaps of various maturities, we estimate reduced-form models of correlated default timing in the CDX High Yield and Investment Grade portfolios under actual and risk-neutral probabilities. The striking contrast between the estimated processes followed by the actual and risk-neutral arrival intensities of defaults, and between the parameters governing the actual and risk-neutral dynamics of the risk-neutral intensities, indicates the presence of substantial default risk premia in CDX swap market rates. The effects of risk premia on swap rates covary strongly across maturities, and depend on general stock market volatility and several measures of credit spreads. Large moves in the effects of these premia on swap rates have natural interpretations in terms of economic and financial market developments during the sample period, April 2004 to October 2007. Our results suggest that a large portion of the movements in CDX swap market rates observed during the sample period may be caused by changing attitudes toward correlated default risk rather than changes in the economic factors affecting the actual risk of clustered defaults, which ultimately governs swap payoffs.  相似文献

The aim of this paper is to explore the influence of consumer‐generated representations on symbolic brand meaning. The term consumer‐generated representation is used in this research to refer to the image created for a brand based on the defining characteristics of a consumer or group of consumers. A preliminary qualitative study consisting of 12 in‐depth interviews was conducted in Kuwait, specifically exploring Muslim female consumers as consumers of western luxury fashion brands. The findings show that Muslim female consumers generate “Modestly Sexy” representations that recreate meaning for western luxury fashion brands in Kuwait. Thus, marketers need to recognize the importance of managing consumer‐generated representations on a global scale.  相似文献

Exploiting data from Ghanaian schools’ eighth grade students collected in 2011, we estimate the causal effects of school bullying on academic achievement and gender-based mitigating approaches by using propensity score matching (PSM) and doubly robust (DR) estimator approach. We find that students victimized by bullying score at least 0.22 standard deviation lower than their peers in a standardized mathematics examination. Meanwhile, we document that the effect of bullying is significantly attenuated in the presence of female teachers in the classroom. These results hold through a set of robustness checks including placebo regressions and matching quality test. We explain the results through gender difference in teaching paradigm and conclude that a feminine management approach in class is required to reduce the effect of bullying.  相似文献

We know very little about how big data-driven service analytics capabilities (SAC) are built in data-driven service organizations and the potential role of talent capability in facilitating overall SAC and the impact of both on firm performance (FPER). Drawing on the dynamic capabilities (DC) approach, this study investigates the link between SAC and FPER examining the mediating role of talent capability and the moderating influence of a firm’s strategic alignment. On the basis of two Delphi studies and survey data from 267 service analysts in the US and France, the findings show that even though SAC are built on technology, talent and information capabilities, their overall impact on firm performance is mediated by the level of talent capability of service analytics managers. The findings also confirm the critical moderating impact of strategic alignment between dynamic talent capability and firm performance in the big data environment.  相似文献

An intertemporal model of an open economy incorporating risk in the export price is developed. It is shown how the optimal trajectories for consumption, investment, growth, exports, and resource allocation can be determined using dynamic stochastic programming. The risk sensitivity and time effects of the various trajectories are analyzed for the case of a logarithmic social utility function. Interestingly, the results obtained are not all in conformance with the conventional results of portfolio theory analysis as applied to savings.  相似文献

Abstract:   This paper conducts a UK test of a version of the Ohlson (1995) model. We should only expect abnormal earnings to revert to zero if the book value of assets is economically meaningful. In this paper we make use of the property revaluations common in UK accounts, but estimate other asset values and earnings in inflation‐adjusted terms. This, we argue, gives rise to estimates of abnormal earnings that can reasonably be expected to revert to zero. We then test this modified model on UK data using the Dechow, Hutton and Sloan (1999) method. In line with the predictions of the Ohlson model, we find that these modified abnormal earnings appear to mean revert, and that a first order autoregressive process is sufficient to capture the persistence of UK real abnormal earnings. The modified abnormal earnings model in general predicts one year ahead earnings more successfully than an unmodified model. Furthermore, for much of the sample period, one year ahead predictions of abnormal earnings are better for the real model during periods of higher inflation. The undervaluation problem found in prior studies appears to be replaced with an overvaluation problem in the real model which is more acute during periods of high inflation. Last, we show that an estimate of the model based upon an industry level specification appears to perform no better than a market‐wide specification of the model.  相似文献

This study addresses how a stock market prices earnings components around a sudden and severe economic downturn. In particular, the study examines the market valuation of discretionary accruals for debt renegotiating Malaysian firms during the Asian financial crisis. Our analysis shows that negative discretionary accruals for debt renegotiating firms are associated with higher market values of equity and are not related to the firms' future earnings. These findings are consistent with investors placing a positive value on the probability that negative accruals increase the likelihood that concessions can be extracted from lenders during renegotiation. In contrast, discretionary accruals for a control sample of non-debt renegotiating firms are not significantly associated with stock prices but are positively associated with future earnings.  相似文献
