The worldwide increase in societal challenges is putting pressure on humanitarian organizations to develop sophisticated approaches to leverage social innovations in the humanitarian sector. Since humanitarian problems are complex problems, with the relevant knowledge being hidden, organizational search theory advocates the application of bottom‐up and theory‐guided search processes to identify the social innovations that solve these. Unfortunately, there has been no theoretical attention to understanding which approaches apply in this context. Further, established theory‐guided bottom‐up search processes, such as the lead user method, are unsuitable to the humanitarian sector, and we lack practice examples of adequate search processes. To start addressing this gap in theory and practice, procedural action research was done with the International Federation of Red Cross and Red Crescent Societies to develop a theory‐guided bottom‐up innovation search process for the real‐life humanitarian problem of recurring floods in Indonesia. It revealed that an innovation search process for this context must differ significantly concerning its objectives and the steps to be taken from the lead user method, which was used as a starting point. Further, a comparison of the technical quality and the social impacts of the identified social innovations with social innovations identified through a non‐theory‐guided bottom‐up search process (i.e., an innovation contest) suggests the superiority of this theory‐guided search process. With this conclusion and the insights derived throughout the development of the search process, this study makes important contributions to theory development in the social and open innovation literatures and delivers important recommendations for social innovation practice in the humanitarian sector.  相似文献

This paper integrates the insight that exporting firms are typically more productive and employ higher‐skilled workers into a directed search model of the labour market. The model generates a skill premium as well as residual wage inequality among identical workers. A trade liberalization increases the skill premium and likely increases residual inequality among high‐skilled workers. The calibrated model generates results consistent with the prior literature examining the effect of the Canada‐US Free Trade Agreement on the Canadian labour market: a significant decrease in employment in manufacturing, but only a small change in unemployment and wages.  相似文献

This study examines financial reporting quality (FRQ) effects around voluntary International Financial Reporting Standards (IFRS) adoptions by German private firms across two important dimensions, earnings quality and disclosure practices. To capture differences in the motivations for IFRS adoptions, we identify four different types of IFRS adopting firms based on a comprehensive set of firm characteristics. We observe earnings quality improvements around IFRS adoptions primarily for one type of firm, which is young, fast growing and seeking access to public equity markets. Using a matched sample of private German GAAP and IFRS reporting firms, we find some evidence suggesting that IFRS also contribute to higher earnings quality. Recognizing that our earnings quality metrics are only incomplete measures of FRQ, we also compare the disclosure practices of IFRS and German GAAP firms. We find that all IFRS firm types disclose significantly more information in their financial reports and show a higher propensity to publish their financial reports voluntarily on the corporate website. Our findings indicate that failure to identify earnings quality changes around IFRS adoption cannot be automatically interpreted as IFRS adoption having no effect on the FRQ of (private) firms. Collectively, our results suggest that both incentives and accounting standards shape private firms’ FRQ.  相似文献

Electronic customer-to-customer interaction (eCCI) becomes crucial in innovative business models (e.g., Ebay, Facebook) that are either intentionally built on such eCCI occurring completely on purpose or for providers that are embedding web 2.0 and social media techniques in their service offering. To enable a more active application and purposeful management of eCCI, it is essential to conceptualize its quality (eCCIq) as a start. In doing so we identify seven factors that constitute the domain of eCCIq: ‘Content’, ‘Security’, ‘Hedonic’, ‘Quantity’, ‘Atmosphere’, ‘Convenience’ and ‘Social’. Construct development is based on existing literature on CCI and various closely-related constructs as well as on an empirical study assessing eCCIq in a qualitative and quantitative manner. Our results enable firms to more selectively influence and control eCCIq and provide the basis to conduct any further research on the impact of eCCI and its quality.  相似文献

A significant change in trends regarding energy prices (in particular oil) has taken place in 2003 at the beginning of the Iraq War. It has revealed a very strong tension between oil prices on the one hand and the relationship between global oil supply and demand on the other. The strong growth rates of emerging economies up to 2008 have generated a very sharp increase in oil prices. The temporary economic recession of 2008-2009 has resulted in turn into a significant decrease of oil prices, down to a level which remained, however, twice as high as that of early 2003. With the economy recovering from the recession, it is highly probable that energy prices will continue to increase and that Europe will be confronted with high energy prices in the coming decades. Against this general background, two scenarios have been elaborated which differ mainly by the time of occurrence of oil peaking.1 The differences between the scenario hypotheses are therefore differences of context in relation to exogenous factors. Policies are also considered in the scenarios, but they are not at the forefront and their impact is considered as limited in relation to that of exogenous factors.The first scenario “Europe in a context of high energy price” assumes that the process of oil peaking will not take place before 2030, but that oil price increase will nevertheless be sustained and substantial until then. Numerous adjustments will have to be made in the economy and their territorial impacts will be significant (less polycentricity, more compact cities, decline of the importance of road and air transport). The second scenario “Europe after oil production peaking” assumes that oil production will peak around the mid-2010s (followed by gas production peaking around 2025), despite significant investments to increase production. In a context of steadily growing oil and gas demand, Europe will be confronted with serious economic difficulties. The territorial impacts will be different from those suggested by the first scenario, with stronger pressure put on rural areas and a loss of attractiveness of large cities related to increasing unemployment and social tensions. In both scenarios, the countries of central and eastern Europe will be more severely hit by the new energy context.The scenarios were elaborated in 2005 and slightly reviewed in 2009 in order to take account of the impacts of the economic recession in Europe and of the growing concerns about climate change.  相似文献

(G)ARCH-type models are frequently used for the dynamic modelling and forecasting of risk attached to speculative asset returns. While the symmetric and conditionally Gaussian GARCH model has been generalized in a manifold of directions, model innovations are mostly presumed to stem from an underlying IID distribution. For a cross section of 18 stock market indices, we notice that (threshold) (T)GARCH-implied model innovations are likely at odds with the commonly held IID assumption. Two complementary strategies are pursued to evaluate the conditional distributions of consecutive TGARCH innovations, a non-parametric approach and a class of standardized copula distributions. Modelling higher order dependence patterns is found to improve standard TGARCH-implied conditional value-at-risk and expected shortfall out-of-sample forecasts that rely on the notion of IID innovations.  相似文献

In this study, we examine whether audit committee accounting expertise helps to promote audit quality by motivating auditors to conduct diligent internal control audits and make appropriate internal control assessments because audit committee accounting expertise safeguards auditors from dismissal following adverse internal control opinions. Among clients with existing and likely internal control material weaknesses (as proxied by future restatements of audited financial statements), we find a greater likelihood of adverse internal control audit opinions when the audit committee has greater accounting expertise (measured by the proportion of accounting experts on the audit committee). Among all clients, we find a lower likelihood of subsequent auditor dismissal following an adverse internal control audit opinion when the audit committee has greater accounting expertise. In further analyses, we find that this lower likelihood of subsequent auditor dismissal occurs when at least two audit committee members possess accounting expertise. We also find some evidence that CFO influence (but not CEO influence) over the audit committee negates the increased likelihood of adverse internal control opinions when internal control material weaknesses likely exist, as well as the decreased likelihood of auditor dismissal following adverse internal control opinions. These findings have important implications for regulators and corporate nominating committees interested in promoting audit committee effectiveness.  相似文献

This study tests for underreaction and overreaction in European large cap markets by examining the abnormal returns of those stocks in the EuroStoxx 50 Index following large price increases and decreases. We find that large price increases and declines tend to be followed by average market returns. Thus, our results support the efficient market theory, rather than any of the behaviour finance hypotheses. This insight is contrary to price patterns found in various national markets.  相似文献
