Using quantile regressions, this paper examines the possibility of significant nonlinear relationships between the profitability of Portuguese service small- and medium-sized enterprises (SMEs) and its specific determinants. The results lead to the conclusion that there is a significant nonlinearity between specific determinants and profitability in Portuguese service SMEs. In the lower quantiles of the distribution of profitability of Portuguese SMEs, it is found that profitability on the one hand is catalysed by size, long-term debt and managerial control, and on the other hand, it is restricted by risk and research and development intensity. In the upper quantiles of the profitability distribution of Portuguese service SMEs, liquidity and research and development intensity serve as catalysers of profitability, while long-term debt restricts the level of profitability. 相似文献

This study analyzes the effect of informational clues and Chef-Cuisine congruence, and their relation to advertisements for a Japanese restaurant. Two experiments were conducted with 171 consumers. Findings supported the following: Congruence between a Japanese restaurant and Japanese Chef results in higher approval ratings than the combination of Japanese restaurant with Brazilian Chef. However, if the advertisement states that the restaurant has won an award, then Chef-restaurant congruence is no longer an important factor in consumers’ evaluations. 相似文献

Consider N independent stochastic processes \((X_i(t), t\in [0,T])\), \(i=1,\ldots , N\), defined by a stochastic differential equation with random effects where the drift term depends linearly on a random vector \(\Phi _i\) and the diffusion coefficient depends on another linear random effect \(\Psi _i\). For these effects, we consider a joint parametric distribution. We propose and study two approximate likelihoods for estimating the parameters of this joint distribution based on discrete observations of the processes on a fixed time interval. Consistent and \(\sqrt{N}\)-asymptotically Gaussian estimators are obtained when both the number of individuals and the number of observations per individual tend to infinity. The estimation methods are investigated on simulated data and show good performances. 相似文献

We examine the innovation performance of MNE subsidiaries and their embeddedness in sources of local knowledge in a policy
framework within the context of an emerging economy. Based on first-hand evidence from multiple case studies, we found that:
(1) there was variability between the subsidiaries in terms of the cumulative manner and speed at which they improved their
innovation performance over time, using progressively levels of accumulated capability as a proxy; (2) these differences in
innovation performance improvement reflected heterogeneity between the subsidiaries in terms of the learning efforts made to acquire knowledge from local organizations; (3) the varied frequency in which the subsidiaries developed such local
relationships reflects their differing responses to a common industrial policy that makes use of tax incentives to stimulate
such links. The paper reveals the limitations of this conventional type of industrial policy in stimulating industrial development
and the embeddedness of MNEs. It also suggests that a new direction for policy, which incorporates public–private negotiations
and a focus on the firm-centred building of innovation capabilities, should be pursued in order to accelerate the innovation
performance progress of latecomer firms. 相似文献

This article discusses the asymptotic and finite‐sample properties of the CUSUM tests for detecting structural breaks in volatility when the data are perturbed with (additive) outliers and/or measurement errors. The special focus is on the parametric and non‐parametric tests in Inclán and Tiao (1994) and Kokoszka and Leipus (2000) . Whereas the asymptotic distribution of the former can be largely affected, the distribution of the latter remains invariant and renders consistent break‐point estimates. In small samples, however, large additive outliers are able to generate sizeable distortions in both tests, which explains some of the contradictory findings in previous literature. 相似文献

This article presents the process of creation and expansion of the Fundação Abrinq pelos Direitos da Criança et do Adolescente (Abrinq Foundation for Rights of Children and Adolescents). Established in 1990 by a group of entrepreneurs from the Brazilian Toy Manufacturers’ Association (ABRINQ), the Fundação Abrinq has been successful at raising the issue of children in Brazilian society by bridging business and several other sectors of society. This article more particularly examines (1) the societal challenges related to the situation of children in Brazil; (2) the creation and development of the Abrinq Foundation; and (3) the achievements of this innovative bridging organization over 15 years. 相似文献

This paper aims to identify some factors that may be explaining differences among secondary students in start-up intentions.
For that, the study develops an entrepreneurial intention model sustained by the use of Azjen’s Theory of Planned Behaviour
(TBP). Using a sample of students aged between 14 and 15 years old, a questionnaire based on the Li?án and Chen’s Entrepreneurial
Intention Questionnaire was administrated. The purpose is to test a model of entrepreneurial intention using structural equations.
The findings point that TPB is an appropriate tool to model the development of entrepreneurial intention through pedagogical
processes and learning contexts. The education and training should centre itself much more in changing personal attitudes
than in knowledge. Moreover, it is desirable that an entrepreneurship educational programme could contribute to the development
of competences related to entrepreneurship, social and civic skills, and cultural awareness. 相似文献

Do individual top managers matter for wages and wage policies? Are there general differences in “style” among managers with respect to worker compensation? To shed light on these questions, we exploit a large panel dataset from Portugal that allows us to match workers, firms, and managers, and follow the movements of the latter across different firms over time. While accounting for the effect of worker and firm heterogeneity, we estimate the role of top manager fixed effects in determining wages and wage policies. The estimates suggest that (i) top managers have a significant influence on wages and wage policies; (ii) there exists different managerial “styles”; and (iii) managers’ (observable) attributes matter for worker compensation. 相似文献
