The research investigated whether economic context and prior financial reinforcement/punishment moderate the effectiveness of marketing behavior in generating gains for the firm. An experiment with a longitudinal design was conducted using 1,759 companies from 2000 to 2017. The results demonstrate that marketing is effective in gaining market share when the country's economy is growing. In contrast, it increases return on assets and Tobin's Q when the country's economy is in recession, this increase being maximized when the company was financially reinforced. The study helps explain the circumstances in which marketing activities boost firms' financial gains. 相似文献

Setting the right approach for new product development (NPD) in the presence of uncertainty remains an ongoing debate in innovation management. Stage-gate systems (SGS) and agile methodology (AM) are the dominant approaches. Recently, hybrid approaches (combining SGS and AM) have been proposed. Although these hybrid approaches represent a significant development in NPD, combining them without considering their design principles might lead to contradictory and competing conceptual formulations, thus increasing the difficulty of comparison among studies. Moreover, scholars and practitioners may struggle to understand when, why and how a certain configuration of the NPD process provides the right response to different manifestations of uncertainty. The current literature faces problems regarding the clarity of design principles (e.g. flexibility and adaptability), and this has led to research gaps concerning the uncertainty contingency and outcomes of hybrid approaches. This study combines bibliometric and content analyses to identify four design parameters and principles of NPD hybrid approaches: flexibility, adaptability, velocity and integration. Our findings might help advance the development and comparison of different hybrid approaches. 相似文献

Opening the black box: Finding the source of cost inefficiency 总被引:2,自引:0,他引:2
Santiago Carbó Valverde David B. Humphrey Rafael López del Paso 《Journal of Productivity Analysis》2007,27(3):209-220
Parametric and nonparametric procedures are used to identify the apparent source of cost inefficiency in banking. Inefficiencies
of 20–25% from earlier studies are reduced to 1–5% when, in addition to commonly specified cost function influences, variables
reflecting banks’ external business environment and industry indicators of “productivity” are added. These productivity indicators
explain most of the reduction in bank operating cost over 1992–2001 and was 5 times the reduction in the dispersion of inefficiency.
Inefficiency appears stable over time because it is small relative to industry-wide cost changes occurring concurrently and
because technology dispersion is imperfect.

Since 2002, the Institute for Peace Promotion and Injury/Violence Prevention (CISALVA) at the Universidad del Valle, Cali, Colombia and the Colombia Program at Georgetown University have developed and implemented 21 epidemiologically based municipal crime observatories in intermediate-sized municipalities in Colombia. These crime observatories serve as monitoring centres that provide low cost, geo-referenced methods of data collection and analysis, which allow cities to develop more responsive policies and prevention programmes and enhance governance. This article focuses on the methodology employed and lessons learned that may be applicable to similar settings. Worth noting within the results was a significant decrease in homicides after the first year of the programme. Whether or not such results could be attributed to the method or to the nature of the interventions and policy initiatives stemming from it remains open to conjecture. 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

The external business environment is a major determinant of which sources firms select to obtain financial capital. We examine how the regulatory, political, and financial dimensions of the institutional environment influence the extent to which firms rely on informal sources of financial capital. The analyses of data from 2869 firms in twenty-six transition economies in Central and Eastern Europe (CEE) indicate that ineffective regulatory system, underdeveloped financial system, and government corruption are strong determinants of firms' reliance on informal channels for financial capital. We also find that smaller firms are more vulnerable when the local financial system is underdeveloped and the regulatory institutions are less effective in these transition economies. A subgroup analysis of firms' forms of establishment shows that private firms are sensitive to the level of development of the local financial system and state-owned enterprises are particularly sensitive to the degree of corruption. 相似文献

In this paper we address the problem of information overload in synchronous group work: the large quantity of information, multiple information sources, and the need to sustain reciprocal interdependence have a negative impact on the capacity to attend to the group. We propose a group attention model characterizing the dynamic coupling between the group members and the mediating technology. Based on that model, we developed a compensation mechanism capable to estimate the most adequate time to raise the users?? attention to the group. We describe how this compensation mechanism was applied to synchronous brainstorming and present results from a laboratory experiment. The obtained results indicate that groups using the compensation mechanism produced 9.6% more ideas when compared to the control groups. A detailed post-hoc analysis of the data obtained in the experiment also indicates that users using the compensation mechanism had 7.5 s of extra uninterrupted time to think about and type an idea, which they began to write 6.4 s sooner, and completed in 4.2 s less time. 相似文献

We examine the exports versus foreign direct investment (FDI) decision under demand uncertainty for an asymmetric cost duopoly. One of the firms can lead entry before demand realization or retain flexibility enjoying an informational advantage. When the time value of information is small and for sufficiently low investment costs, follow‐the‐leader behavior in FDI arises. Relatively high investment (fixed) costs result in follow‐the‐leader exporting behavior. When the time value of information becomes significant, the potential leader will opt for a wait‐and‐see strategy. For intermediate values of investment costs, the efficient firm invests, while the rival chooses to export. 相似文献

When modelling rating transitions as continuous-time Markov processes, in practice, time-homogeneity is a common assumption,
yet restrictive, in order to reduce the complexity of the model. This paper investigates whether rating transition probabilities
change after the origination of debt. Accordingly, we develop a likelihood-ratio test for the hypothesis of time-homogeneity.
The alternative is a step function of transition intensities. The test rejects time-homogeneity for rating transitions observed
over 7 years in a real corporate portfolio. Especially 1-year transition probabilities increase over the first year after
origination. This time effect suggests that banks should manage their credit portfolios with respect to the age of debt.

This paper examines Portuguese firms’ survival over the business cycle and investigates whether the effect of firm size varies across the phases of the cycle and with the type of shock associated with periods of economic contraction. Our results show that smaller firms are more likely to shut down than larger firms. Within each size band, however, we found that during the two crises examined, micro firms experienced hazards of closing (relative to large firms) at least similar to those observed in the pre-crisis period, while medium-sized firms were found to have been more vulnerable during the financial crisis period but showed more resilience during the sovereign debt crisis. The results suggest that during the sovereign debt crisis, firms faced a higher probability of closing than they did during the financial crisis. 相似文献
