We investigate the effect of pre-entry experience on firms’ performance in terms of survival. In particular we focus on entrants from a related upstream industry – semiconductors – into a downstream industry – telecommunications. We examine a sample of 336 de-novo start-ups in the US telecommunication industry and we estimate a discrete time hazard model of firm exit. Our findings show that, after controlling for both firms and founders’ characteristics, firms whose founders had prior experience in a related upstream industry such as semiconductors enjoy a relatively lower hazard of exit with respect to intra-industry spinoffs and other types of start-ups. Additionally, background heterogeneity of the founding team is an important determinant of survival for the firms in our sample. Our results point to the role of interdependences and technological complementarities between two vertically related industries in affecting the performance of new entrants.  相似文献

This paper examines the impact of borrowers’ managerial ability on lenders’ bank‐loan pricing and the channels through which managerial ability affects bank‐loan pricing. Using a large sample of US bank loans, we provide evidence that higher managerial ability is associated with lower bank‐loan prices. This effect is stronger in firms with high information risk, suggesting that an important channel for managerial ability to affect bank‐loan pricing is through improved financial disclosure to mitigate information asymmetry. The relationship is also stronger for firms with weak business fundamentals, implying that another channel is through improved business performance. Of these two mechanisms, path analysis suggests that the business‐fundamentals mechanism is the more important channel through which managerial ability affects bank‐loan pricing.  相似文献

This paper focuses on a specific strategy that developers of mobile applications may use to stimulate demand: The release of updates. We develop a theoretical analysis that shows that developers have incentives to release updates when experiencing a drop in performance. The predictions of the model are then tested using an unbalanced panel of top 1,000 apps in iTunes and Google Play for five European countries. We estimate that while in iTunes the release of an update stimulates a 26% increase in download growth, in Google Play updates play a less significant role. This difference is partly due to systematic differences in apps and in developers operating in the two stores (“selection effect”), and partly to a lack of quality control on apps and updates in Google Play (“quality check effect”). These findings highlight the crucial importance of an appropriate management of updates as well as the relevance of institutional characteristics of the app stores.  相似文献

In questo lavoro si considera la classe dei decisori avversi al rischio e per questa classe viene proposto un metodo per verificare la dominanza stocastica tra due possibilità in alternativa quando la funzione d'utilità sia nota soltanto in un numero finito di punti.
This paper deals with the set of adverse to risk decision-makers. For this set a method to check stochastic dominance is proposed. The method works when utility function value is known only on a finite set of points.

Questo lavoro fornisce condizioni di dominanza stocastica di 1°, 2° e 3° ordine per problemi di decisione in condizioni d'incertezza, quando sia nota la funzione d'utilità solo in un numero finito di punti e quando le funzioni di ripartizione dei guadagni aleatori s'intersecano più d'una volta.  相似文献

Small and medium‐sized enterprises (SMEs) are more vulnerable to globalization and rapid technological change due to their scarcity of resources. SMEs' absorptive capacity allows them to access knowledge and plays a key role in their ability to explore and exploit opportunities in their environment. Therefore, this study aims to identify and categorize knowledge management practices which SMEs can adopt to develop absorptive capacity. From a population of 4,534 Portuguese SMEs, 260 usable completed questionnaires were returned. We concluded that Portuguese SMEs are engaged in knowledge management practices, through collaboration with business partners, favoring learning processes based on experience, knowledge transfer to employees and knowledge absorption by employees, reflecting the importance given by SMEs to the tacit nature of knowledge which helps them in efficiency improvements, strategic adaptation, and the launch of new products and services. Our study contributes to advancing theory in the fields of knowledge management and absorptive capacity. We combine and extend previous research which allows us to reconcile the sometimes contradictory findings concerning knowledge management practices which SMEs can adopt to reinforce absorptive capacity. Some theoretical and practical implications are also presented.  相似文献

In this paper, we focus on the role of persistence and heterogeneity of innovative activities at the level of the firm in determining the patterns of technological change in different industries and countries. We ask: are persistence and heterogeneity associated with higher degrees of concentration in innovative activities, stability in the ranking of innovators, and lower degrees of entry and exit in the population of innovators? Or, do the patterns of innovation depend on other variables like firm size and industrial concentration? Moreover, what are the relationships between the patterns of innovative activities, their determinants, and the technological specialization of countries? We compute indicators of persistence and heterogeneity using the OTAF-SPRU patent database at the firm level for five European countries over the period 1969–1986 for 33 technological classes. Then, we estimate the relationships between our indicators of the sectoral patterns of innovative activities and international technological specialization on the one hand, and our indicators of persistence, heterogeneity and market structure on the other. Results show that persistence and asymmetries are important (and strongly related) phenomena that affect the patterns of innovative activities across countries and sectors, while the role of market structure variables is less clear. Finally, international technological specialization is associated to a competitive core of persistent innovators.  相似文献
