Banks’ Net Interest Margin in the 2000s: A Macro-Accounting international perspective

This paper re-examines the determinants of Net Interest Margin (NIM) in the banking industries of 15 developed and emerging economies. It presents three main contributions with respect to previous studies: first, we analyze the determinants of NIM in the years leading to the 2008 financial crisis; second, we account for the role of different accounting standards across countries; third, we use multi-way cluster estimation methodologies which control for cross-sectional and time-series dependence in macroeconomic and banking variables. We find that the introduction of International Financial Reporting Standards (IFRSs) contributed to lower NIM variations unexplained by standard accounting variables. Interest rate volatility is found to be positively and strongly related to NIM dynamics, whereas inflation risk is often found to be a relevant driver of NIM cross-country differences.     

Modelling Electricity Prices: International Evidence*

This article analyses the evolution of electricity prices in deregulated markets. We present a general class of models that simultaneously takes into account several factors: seasonality, mean reversion, GARCH behaviour and time‐dependent jumps. The models are applied to daily equilibrium spot prices of eight electricity markets. Eight different nested models were estimated to compare the relative importance of each factor in each of the eight markets. We find strong evidence that electricity equilibrium prices are mean‐reverting, with volatility clustering (GARCH) and with jumps of time‐dependent intensity, even after adjusting for seasonality.     

South African Capital Structure Decisions: A Survey of Listed Companies

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.     

Romanians,Hungarians and their wages,in transition,in Romania

Legally binding treaties or memorandums have been used over time to regulate the issue of national borders of many European countries. As a result, relatively large groups of people have become ethnic minorities in other countries. They may conserve their ethnic identities, and therefore their children may accumulate ethnic human capital (e.g., language, culture, and religion) in addition to the general human capital of the country. Therefore, they can get access to an appropriate occupation linked by tradition or other factors to their ethnic group. This paper uses estimates from a selection model with an endogenous switch among three broad types of occupational groups to analyze the composition of the wage gap between Romanians and ethnic Hungarians in Romania before and during the transition from a planned to a market economy. The results suggest that the institutional settings of the controlled economy allowed Romanians to work in occupations that gave them the best returns, while the changes during the transition years allowed ethnic Hungarians to work in occupations that gave them the best returns.     

Employment Effects of Offshoring across Sectors and Occupations in Japan

In the case of Japan, the studies conducted so far focus alone on firm‐level data and delve into the productivity effects and the skill upgrading between skilled and unskilled workers. Here, we carry out an empirical analysis of the employment effects of offshoring for Japanese industries on a broader classification of skills or occupations, while considering the three major sectors of the economy and taking account of both services and materials offshoring. The results suggest that various types of offshoring affect occupations differently. In particular, services offshoring tends to benefit highly skilled occupations more, while materials offshoring tends to benefit production workers instead.     

Patterns of care and burden of chronic idiopathic thrombocytopenic purpura in Brazil

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.
