Recently, the global economy assumed a new setting in which emerging economies began to make substantial investments in the international market. This study aimed to investigate the determinants of outward foreign direct investment from Brazil from 2002–2011. The proposed models developed included attractiveness of the host country, characteristics of home country, and firms’ strategies. The results corroborate the existing argumentations concerning adaptation of mainstream theory with respect to the realities of emerging economies. Brazilian multinationals do not internationalize their activities in pursuit of cost reduction, efficiency, or to explore new markets or natural resources of the host countries. Results show that Brazilian investments were attracted by the availability of skilled labor, openness of the host market, geographic proximity, improved financial conditions of Brazilian companies, and national companies’ strategy of reaffirmation and consolidation as global players.  相似文献

This paper studies the international transmission of productivity and monetary shocks in a general equilibrium two-country monetary model with portfolio rigidities and distribution costs in trade. The model features two types of transport costs (iceberg costs and distribution costs in terms of nontradables) and incomplete markets. The specification employed here is able to generate the domestic liquidity effect, increase in the foreign–domestic interest rate differential, and the nominal depreciation after a monetary injection. Quantitatively, the model with distribution costs as in Burstein, Neves and Rebelo (2003) performs better matching some business cycle moments, but fails to generate the high volatility of exchange rates observed in the data.  相似文献

ABSTRACT

This paper explores the factors that influence capital structure decisions in South Africa from the perspective of the Chief Financial Officer (CFO). The results of a survey of 33 CFOs of JSE listed companies find that South African CFOs are equally likely to follow the Pecking Order and Static Trade-Off theories. However, small companies are more likely to follow the Pecking Order theory while large companies are more likely to follow the Static Trade-Off theory. In addition, the results show that South African companies are more likely to follow the Static Trade-Off theory than companies in other emerging countries.  相似文献

Aims: Although several therapeutic options are available for chronic immune thrombocytopenic purpura (cITP), little is known about the treatment of cITP in Brazil.

Materials and methods: A multi-center, retrospective chart review, observational study was designed to describe the treatment patterns, clinical burden, resources use, and associated costs for adult patients diagnosed with cITP and treated in public and private institutions in Brazil. Patient charts were screened in reverse chronological order based on their last visit post January 1, 2012. (All costs were calculated using 1.00 USD?=?3.9571 BRL, from February 2016.)

Results: Of 340 patient charts screened, 50 patients were eligible for inclusion in the study. Single-drug therapy (prednisone, dexamethasone, or dapsone) was the most commonly used treatment, followed by combination therapies (azathioprine?+?prednisone, azathioprine?+?prednisone?+?danazol, and prednisone?+?dapsone). Splenectomy was performed in 22% of patients after at least first-line treatment. Platelet count and number of bleeding episodes at diagnosis were 31,561.1/mm3 (SD?=?±26,396.1) and 40 episodes, respectively; in first-line, 92,631.1/mm3 (SD?=?±79,955.3) and 19 episodes, respectively; in second-line, 96,950.0/mm3 (SD?=?±76,476.4) and 17 episodes, respectively. Private system patients had a higher median cost compared to public system patients (USD 17.49/month, range?=?0–2,020.77 vs USD 9.51/month, range?=?0–192.64, respectively).

Limitations: This study does not allow conclusions for causal explanations due to the cohort study design, and treatment patterns represent only the practices of physicians who have agreed to participate in the study.

Conclusions: The data indicate that available therapeutic strategies for second- and third-line therapies appear to be limited.  相似文献

We study the effects of the Internet on regional price differences. Comparing two Dutch regions, we find that before the rise of the Internet, price differences of used cars between those regions amounted to some 11–15%, controlling for mileage, age, fuel type and engine volume. These price differences have completely disappeared after the rise of the Internet, in particular a website that allows consumers to make detailed comparisons between almost all used cars for sale in the Netherlands.  相似文献

Small-scale firms in rural areas play an extremely important role in the development of any country, and especially in developing countries. To understand entrepreneurs who operate in a low-technology industry, we rely on the network perspective on entrepreneurship. In this paper, we investigate how the social and human capital of entrepreneurs (in this case master weavers in the handloom industry) influence their ability to recognize opportunities and mobilize resources. In addition to examining the direct effects, we also explore the possibilities of social capital mediating between human capital, on the one hand, and opportunity recognition and resource mobilization on the other. This paper adds to existing literature in two ways: firstly, we expand the social capital paradigm by including different cultural settings and links to existing studies regarding small enterprises. Secondly, we provide additional evidence to the ongoing debate as to what constitutes a ‘good network’.  相似文献
