Bank size,competition and risk in the Turkish banking industry

This paper investigates the impact of bank size and competition on earnings volatility and insolvency risk using quarterly data for commercial banks operating in the Turkish banking industry for the period 2002Q1–2012Q2. The main result of the paper indicates that bank size and earnings volatility are negatively related, suggesting that larger banks are less risky. The results also indicate that competition measured by the Boone indicator increases earnings volatility. The results further suggest that higher capitalized banks, banks with a higher share of non-interest income in total income and efficient banks face lower earnings volatility. Finally, insolvency risk measured by Z-score and bank size are positively related, suggesting that larger banks are more stable.     

The impact of interest rate and exchange rate volatility on banks' stock returns and volatility: Evidence from Turkey

This paper investigates the effects of interest rate and foreign exchange rate changes on Turkish banks' stock returns using the OLS and GARCH estimation models. The results suggest that interest rate and exchange rate changes have a negative and significant impact on the conditional bank stock return. Also, bank stock return sensitivities are found to be stronger for market return than interest rates and exchange rates, implying that market return plays an important role in determining the dynamics of conditional return of bank stocks. The results further indicate that interest rate and exchange rate volatility are the major determinants of the conditional bank stock return volatility.     

Performance implications of institutionalization process in family-owned businesses: Evidence from an emerging economy

This paper attempts to understand the role of two highly relevant founder family characteristics, harmony among family members and the degree of democratization in decision-making, in the institutionalization and adaptive capability development processes of family firms in Turkey as an exemplar of an emerging market. The paper examines how institutionalization and adaptability jointly drive firm-level differences in quantitative (i.e., sales growth, market share, and return on investment) and qualitative performance (i.e., quality of goods/services, new product development, employee satisfaction) components. Data were collected from 436 respondents in 132 family firms through structured questionnaires administered to at least three respondents from each firm. Findings indicated that among the institutionalization dimensions, transparency had the strongest effect on both quantitative and qualitative firm performance, whereas adaptability influenced qualitative performance only. Harmony in family relations increased efforts for institutionalization, whereas democracy in decision-making enhanced adaptability. Implications of these findings are discussed and several future research directions are suggested.     

Technical Change in Banking: Evidence From Transition Countries

This paper investigates the effect of technical change on the costs of banking firms operating in 11 Central and Eastern European countries using Fourier‐flexible cost function specification for the period 1995–2002. A common cost frontier with country‐specific variables is employed in order to take into account macro‐economic and regulatory conditions that vary over country and time. Our findings suggest that the rate of reduction in costs resulting from technical change increased during the sample period. Banks operating in Hungary, Czech Republic and Poland benefited more from technical change than their counterparts. In terms of cost reduction, large banks benefited more from technical progress. This indicates that large banks are more able to change their optimal input mix in response to changes in technology.     

Dual long memory property in returns and volatility: Evidence from the CEE countries' stock markets

This paper investigates the presence of long memory in the eight Central and Eastern European (CEE) countries' stock market, using the ARFIMA, GPH, FIGARCH and HYGARCH models. The data set consists of daily returns, and long memory tests are carried out both for the returns and volatilities of these series. The results of the ARFIMA and GPH models indicate the existence of long memory in five of eight return series. The results also suggest that long memory dynamics in the returns and volatility might be modeled by using the ARFIMA–FIGARCH and ARFIMA–HYGARCH models. The results of these models indicate strong evidence of long memory both in conditional mean and conditional variance. Moreover, the ARFIMA–FIGARCH model provides the better out-of-sample forecast for the sampled stock markets.     

Nominal and real convergence between the CEE countries and the EU: a fractional cointegration analysis

This paper examines the real and nominal convergence between the Central and Eastern European countries and the EU, using fractional cointegration analysis for the period 1980–2003. Fractional cointegration analysis is a flexible methodology, which allows for more subtle forms of mean reversion. The tests performed are those of Geweke and Porter-Hudak. The convergence processes are valid when macroeconomic time series used in the study are fractionally cointegrated. The results indicate that inflation and interest rates series of six sample countries are fractionally cointegrated with those of the EU. Therefore, nominal convergence has been achieved by some of the transition countries, but the equilibrium errors display long memory. Results also indicate that industrial outputs of most countries in the sample are not fractionally cointegrated with that of the EU. The results further indicate that both nominal and real convergence have been achieved only for Hungary.     

Health state utilities associated with treatment options for acute myeloid leukemia (AML)

Abstract

Aims: Acute myeloid leukemia (AML) treatment typically involves remission induction chemotherapy followed by consolidation chemotherapy. New treatments for AML have recently been introduced, including a chemotherapy formulation called CPX-351, which is administered via less time-intensive IV infusion than the standard “7?+?3” continuous infusion regimen of cytarabine plus an anthracycline. The purpose of this study was to estimate utilities that could be used in economic modeling of AML treatment.

Materials and methods: In time trade-off interviews, participants from the UK general population valued 12 health states drafted based on literature and clinician interviews. To identify disutility associated with chemotherapy, two types of induction and four types of consolidation were added to an otherwise identical health state describing AML. The decrease in utility when adding these chemotherapy regimens represents the disutility of each regimen. Five additional health states were valued to estimate utilities associated with other AML treatments.

Results: Two hundred participants completed interviews. Mean (SD) utilities were 0.55 (0.31) for pre-treatment AML and 0.66 (0.29) for AML in temporary remission. Adding any chemotherapy significantly decreased utility (p?<?0.0001). Induction had a mean disutility of –0.11 with CPX-351 and –0.15 with 7?+?3. Mean disutility for consolidation ranged from –0.03 with outpatient CPX-351 to –0.11 with inpatient 5?+?2. Utilities are also reported for other AML treatments (e.g. transplant, low-intensity chemotherapy).

Limitations: One limitation is that the differences in adverse event profiles between the treatment regimens were based on clinician opinion. Future use of CPX-351 in clinical trials or clinical settings will provide additional information on its adverse event profile.

Conclusions: While all chemotherapy regimens were associated with disutility, regimens with shorter hospitalization and less time-intensive infusion were generally perceived as preferable. These utilities may be useful in cost-utility models comparing the value of AML treatments.     

The Influence of Funding Approaches,Growth Expectations,and Industry Gender Distribution on High‐Growth Women Entrepreneurs

This study examines three key aspects of entrepreneurship associated with women business owners and their ability to achieve high growth: debt versus equity financing, growth expectations, and industry gender distribution. We present a number of theoretical lenses spanning disciplines such as gender studies, entrepreneurship, social psychology, and finance. Using longitudinal data from U.S. startups over an eight‐year period, our research reveals a number of interesting findings. We find that, proportionally, high‐growth women entrepreneurs are more likely to finance their growth with personal and business equity funding. Additionally, women‐owned firms in “feminine industries” are more likely to achieve high growth than women‐owned firms in “non‐feminine industries.”     

The degree of integration in strategic alliances in biotechnology

This paper looks at the spection of strategic alliances in biotechnoloy in the late 1980s from the point of view of whether the alliance was of a contractual type or, at the other end of the spectrum, have integrated the two companies of the alliance were. It uses an ordered probit model to test for any systemalic association between alliances within indeustrial sectors and of different size types, and the type of alhance that occurred. The paper find that more contractual, less integrated types of alliance were concentrated in the healtheare secters of thenapeutics and diagnostics and where at least one of the firms was small in size. More integrated types of alliance revailed in the agriculature and cheicals sectors and between two lage companies. It relates these results to conditions of appropriability, the impact of the new lechnologies on existing compelencies and absorptwe capacity within the different industrial sectors at that time. It compares the situation of the late 1980s with more recnt developments in corporate strategy lowards allliance formation.
