Even though the choice of capital structure depends on the three different financial components of foreign direct investment (FDI), previous research has regarded FDI as unidimensional rather than multidimensional. This study addresses new findings in the FDI area and investigates the relevant determinants of capital structure in 30 OECD countries from 2006 to 2014 within the framework of a simultaneous equation model. Our primary findings reveal that each component has its own deterministic features driven by relevant policy variables and risks in the market. While an increase or decrease in equity capital shows the ability of the host country to attract new investments, the subsequent components are mostly used to adjust the equity capital investment exposure.  相似文献

We study the effects private equity (PE) and venture capital (VC) financing have on small and mid-sized single entity business establishments from 1995 to 2009. We focus on single entity establishments to cleanly examine the impact of PE and VC financing on establishments’ organic growth. This study reveals that PE and VC financing have positive impacts on single entity business establishments’ net sales and employment growth. The impact of PE financing on establishments’ growth is slower and smaller than VC financing. However, we find that the benefit of PE financing lasts longer than VC financing. We also find that ethnic minority, female, and foreign business owners are less likely to receive PE and VC financing. Finally, we find evidence that although establishments with government contracts are more likely to receive PE and VC financing, those contracts fail to produce marginal post-funding growth and employment benefits.  相似文献

This article explores how the adoption of company sponsored smart phones inflicts upon the lives of professionals. Drawing upon qualitative interviews at a law firm in Brazil, the experiences of new smart phone users are reported upon in detail. Increased accessibility, accuracy and speed in exchanges gave the users a sense of autonomy and flexibility. However, the technology also helped to intensify the organisation's hold on employees outside of regular working hours, reaching into new settings, time slots and social contexts. Employees expressed concerns regarding demands from superiors that negatively affected their private spheres, yet many of them paradoxically requested more efficient smart phone connectivity. The article focuses on the justifications, the different narrative strategies, employed by professionals for their conscious engagement in escalating work connectivity. It is suggested that these justifications display users' attempt to ‘dis‐identify’ with the role and practice they perform.  相似文献

As documented in the literature, the effects of firm size, financial leverage, and R&D expenditures on firm earnings are inclusive. Our hypothesis is that the inconsistent empirical results of such effects may be driven by the regression models implemented in data analysis. Using the quantile regression (QR) approach developed by Koenker and Basset (1978), this study analyses S&P 500 firms from 1996 to 2005. We find that the effects of firm size, financial leverage and R&D expenditures on firm earnings differ considerably across earnings quantiles. Comparing the results from the QR approach with those from the ordinary least squares (OLS) and least absolute deviation (LAD) methods, this study further explains the puzzling relationship between firm size, financial leverage, R&D expenditures and firm earnings.  相似文献

In the literature on sustainability of agriculture, both labourers and workers are conspicuously absent. Here, the sustainability of agriculture has been defined in terms of whether the farm household in question is able to yield an energy surplus when its members and the animals in its possession are obtaining an adequate ‘energy income’ or Calorie intake. To evaluate the sustainability of 590 farming households in the state of West Bengal, India, during 2004–5, four progressively stricter definitions of sustainability have been proposed, defined and applied. The method of energy balance analysis was followed. A negative surplus was found to be near‐universal across size‐groups in terms of the net area sown (NAS), the gross cultivated area (GCA) and agro‐climatic zones. The threshold output for a non‐negative surplus during the cultivating period was 700,000 megajoules (MJ); in terms of the GCA for a positive ‘full and final’ annual surplus, it was 3 hectares, and in NAS terms it was 2.5 hectares; against NAS per household size, it was 0.6 hectares, for ensuring a positive surplus beyond the annual sustainability. No evidence could be found in favour of household size as an explanation for the negative surplus.  相似文献

Researchers and brand managers have limited understanding of the effects social media communication has on how consumers perceive brands. We investigated 504 Facebook users in order to observe the impact of firm-created and user-generated (UG) social media communication on brand equity (BE), brand attitude (BA) and purchase intention (PI) by using a standardized online survey throughout Poland. To test the conceptual model, we analyzed 60 brands across three different industries: non-alcoholic beverages, clothing and mobile network operators. When analyzing the data, we applied the structural equation modeling technique to both investigate the interplay of firm-created and user-generated social media communication and examine industry-specific differences. The results of the empirical studies showed that user-generated social media communication had a positive influence on both brand equity and brand attitude, whereas firm-created social media communication affected only brand attitude. Both brand equity and brand attitude were shown to have a positive influence on purchase intention. In addition, we assessed measurement invariance using a multi-group structural modeling equation. The findings revealed that the proposed measurement model was invariant across the researched industries. However, structural path differences were detected across the models.  相似文献

The industries in which listed firms are concentrated in less developed equity markets are not random, nor entirely explained by the underlying composition of production. Listed firms and market capitalization are disproportionately concentrated in industries with low beta (measured with their beta with the market portfolio in the U.S.). We document a strong positive relationship between the industry-weighted country beta and the degree of market development across countries. Recent IPO activity confirms the result since new listings have higher betas than the average firm already in the market.  相似文献

This paper explores a wide range of corporate restructurings, all available deals from wire services, in the banking and insurance sectors that led to bancassurance ventures. An event study methodology is employed to calculate excess returns on and around the deals’ announcement date. Using both univariate and multivariate analysis the paper finds bank driven mergers, deal's size and regional categorization all triggering positive and significant market reactions. Unlike the univariate framework, multivariate analysis shows that geographic focus and language are not significant factors. The results also indicate that markets are indifferent with respect to bank withdrawals from the bank‐insurance operations. Finally, Canadian, U.S. and European bank‐insurance deals produce positive results, while Australasian bidders offer statistically insignificant equity returns.  相似文献
