Enterprise architecture allows companies to deal with digital transformation through the proactive presentation and alignment of business and IT in a holistic manner. One important challenge is EA modelling since it is time-consuming (thus expensive), error-prone, and biased owing to experts’ subjective opinions. This challenge might consequently be addressed through automatic EA modelling. We conducted a systematic mapping study to classify and evaluate the research concerning EA mining proposals developed specifically for TOGAF and Archimate. After analysing results, we concluded that the research field is not sufficiently mature and further research on EA mining is necessary. 相似文献

Controversy over labor market policy often centers on achieving a balance between preventing worker exploitation, and avoiding loss of productivity or employment through excessive regulation. Although the literature documenting the impact of labor market regulation on employment is extensive, there is a dearth of evidence on the impact of such policies in low‐income countries (LICs). Since it is easier for workers, especially women, to slip into the informal sector in LICs, regulations are likely to have stronger impacts on formal employment in these countries (but lower impacts on unemployment). We systematically reviewed available research from countries that are, or were until recently, LICs. Most studies document that more stringent labor regulations are associated with lower formal sector employment and higher informal sector employment. We also conducted a metaregression analysis of the impact of minimum wages on formal and informal employment. After controlling for publication bias, higher minimum wages are associated with lower formal employment and a higher share of informal workers. 相似文献

Our study analyzes rivalry within and across markets of size‐defined strategic groups in the banking industry. We consider that, owing to group‐level effects, like efficiency and funding, the degree of rivalry of size‐defined strategic groups depends on whether the competitor is acting in the same or in a different market and whether the competing firms are within the same strategic group or in different groups. We estimate the effect of group interactions within and across loans and deposits markets on firm performance in the Spanish banking industry. We find evidences of rivalry as described in our hypotheses. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

Abstract Cross-sector inter-organizational partnerships, alliances and networks have become extremely popular. Yet, we may expect competing societal-level institutional logics to play an important role in cross-sector alliances, hence making their management central to alliance success. This article responds to the general research question: How do participants of public–private joint ventures manage competing institutional logics? Based on in-depth interviews we empirically characterize two competing logics in a cross-sector collaborative and identify two practices used to cope with them. 相似文献

The analysis of poverty measures has been receiving increased attention in recent years. This paper contributes to the literature by developing percentile ratio estimators based on the pseudo empirical likelihood method. In practice, variances of poverty measures could be not expressible by simple formulae and consequently other techniques should be used in the variance estimation stage. Assuming percentile ratios, resampling techniques are investigated in this paper. A numerical example based on data from the Spanish Household Panel Survey is taken up to illustrate how suggested procedures can perform better than existing ones. The effect of a model-misspecification on the proposed estimators is also evaluated by using simulated populations. 相似文献

The main purpose of this paper is to analyse the association between open inbound knowledge strategies and the performance of eco‐innovative firms in the food and beverage industry. We propose a mixed framework based on the eco‐innovation literature and the open innovation approach. We consider the characteristics in a traditional sector based upon a resource‐based perspective. Three types of firms are distinguished in terms of their sales growth in the Spanish food industry from the least to the most successful eco‐innovators. Using multinomial logistic regression models, it is shown that the diversity of collaborators (breadth of external sources of knowledge) and joint adoption of product and process eco‐innovations are positively associated with the probability of achieving high sales growth. Moreover, we find an inverted U‐shaped relationship between the breadth of the external search and firm performance, but only for the group of the most successful firms. Moreover, operational flexibility, knowledge‐based capabilities and company size are also positively related to the group of successful eco‐innovators. 相似文献

Khanna and Yafeh hypothesize that business groups should be more common in economies with less developed markets and institutions. We test the time‐series version of this hypothesis by looking at changes in Chilean groups over 20 years (1990–2009). In this period, Chile experienced a deep economic transformation as measured by common proxies of market development (e.g., per capita income doubled). Despite this dramatic transformation, groups remained mostly unchanged in terms of relative size, industrial diversification, vertical integration, control structures, internal capital markets, and reliance on external funds (minority equity plus debt). Only leverage increased. Also, groups' initial conditions were uncorrelated with market development at the time of formation. This evidence casts doubts on the institutional‐voids hypothesis, although more subtle institutional voids, not captured by the type of macro proxies we use, might explain the existence and resilience of business groups. 相似文献

This survey examines the empirical literature on the relationship between public R&D subsidies and private R&D investment over the past five decades. The survey reveals a considerable heterogeneity of empirical results that cannot be explained fully by methodological issues. We aim to provide further explanations of the possible causes of that heterogeneity. In particular, we emphasise a set of issues that, in our view, are critical to understanding the potential effect of public R&D subsidies on private R&D spending. Special attention is paid to the dynamic aspects and composition of firm R&D, the constraints faced by the firm (such as financial constraints), and the amount and source of public subsidies. None of these issues have been investigated in depth. We formulate a set of research assumptions to guide future empirical research in this field. 相似文献

Distance functions are increasingly being augmented, with environmental goods treated as conventional outputs. A common approach to evaluate the opportunity cost of providing an environmental good is the exploitation of the distance function's dual relationship to the value function. This implies that the opportunity cost is assumed to be non‐negative. This approach also requires a convex technology set. Focusing on crop diversification for a balanced sample of 44 cereal farms in the East of England for the years 2007–2013, this paper develops a novel opportunity cost measure that does not depend on these strong assumptions. We find that the opportunity cost of crop diversification is negative for most farms. 相似文献
