This paper empirically analyses how the adoption of Information Technologies (IT) has changed the organization of global supply chains. We focus on international mergers, which are a growing and important component of foreign direct investment. We use data on North–South mergers and acquisitions (M&As). We show that the effect of IT adoption on the number of vertical M&As is decreasing with the routine intensity of the industry. Our interpretation is that the IT revolution enabled new monitoring mechanisms. This allowed Northern headquarters to better monitor suppliers, especially those in less routine‐intensive industries –which were harder to monitor before. 相似文献

The aim of this work is to study corporate governance (CG) in small and medium enterprises (SMEs) from a gender perspective. In particular, we study the participation of women in ownership, management (board and senior management) and external audit in SMEs participating in the Argentinean Securities Market. The results show that participation of women in ownership and in external audit has a significant relationship with financing decisions. However, we do not find evidence of relations among different levels of GC and gender. 相似文献

The allocation problem for multivariate stratified random sampling as a problem of stochastic matrix integer mathematical programming is considered, minimizing the estimated covariance matrix of estimated means subject to fixed cost or fixed total sample size. With these aims the asymptotic normality of sample covariance matrices for each strata is established. Some alternative approaches are suggested for its solution. An example is solved by applying the proposed techniques. 相似文献

In recent years, there has been an increase in empirical and theoretical work that addresses the role of innovation as one of the main sources of firm growth. The purpose of this special issue is to strengthen the role played by innovation as a determinant of firm growth. Despite the emergence of a vast empirical literature on whether innovative firms grow more quickly in terms of sales and employees, a number of crucial questions and answers remain. While a large number of applied papers observe a positive link between innovation and firm growth, the complexity of R&D activities, together with the diversity of innovation strategies and the multiplicity of growth modes, requires a multidimensional approach to examine the contribution of innovations on firm growth. To shed light on the link between firm’ growth and innovation sources, we organized a meeting of leading scholars of firm’ growth and innovation. The papers of this special issue were presented at the workshop on ‘Firm growth and innovation’ held on 28 and 29 June, 2012, in Tarragona, Spain. The papers that compose this special issue deal in depth with innovation activity, firm growth and the interaction between firm growth and innovation. 相似文献

This paper draws on a sample of innovative Catalan firms to identify how two main sources of innovation – internal R&D and external R&D acquisition – affect productivity in the manufacturing and service industries. The sample comprises 1612 innovative firms from the fourth European Community Innovation Survey (CIS-4) during the period 2002–2004. We compare empirical results when applying the usual OLS and quantile regression techniques controlling with a non-parametric sample selection. Our results indicate the different patterns that are attributable to the two sources of innovation as we move up from lower to higher conditional quantiles. First, the marginal effect of internal R&D on productivity decreased as we moved up to higher productivity levels. Second, the marginal effect of external R&D acquisition increased as we moved up to higher productivity levels. Finally, empirical results show significant complementarities between internal and external R&D, which are higher for knowledge-intensive service sectors. 相似文献

In this article, we examine the convenience of dollarization for Ecuador today. As Ecuador is strongly integrated financially and commercially with the United States, the exchange rate pass-through should be zero. However, we sustain that rising rates of imports from trade partners other than the United States and subsequent real effective exchange rate depreciations are causing the pass-through to move away from zero. Here, in the framework of the Vector Error Correction Model, we analyse the impulse response function and variance decomposition of the inflation variable. We show that the developing economy of Ecuador is importing inflation from its main trading partners, most of them emerging countries with appreciated currencies. We argue that if Ecuador recovered both its monetary and exchange rate instruments, it would be able to fight against inflation. We believe such an analysis could be extended to other countries with pegged exchange rate regimes. 相似文献

This article studies the determinants of the financing decisions of small and medium enterprises (SMEs), which we characterize through three cases: trade-off behavior, pecking order, and extreme aversion to debt. We test our hypotheses using a dataset of firms from Bahía Blanca (Argentina) for two years: 2006 and 2010. We find that firm characteristics related to information asymmetries, such as firm age, size, and legal form; and personal factors, such as owner’s age and education; and perception of emotional bankruptcy costs, are relevant variables in SME financing behavior. The recognition of extreme aversion to debt motivates reconsideration of the underleverage problem of SMEs. 相似文献
