Özet

As is known skewness and outliers are frequently observed in return series, overlooking both concepts during the statistical analysis may cause misleading interpretations. In this paper similar movements of stock markets through the returns of developed and emerging stock markets are recognized and appealing portfolio diversification benefits are identified for investors of USA, UK and Turkey. Different from the previous studies, modified robust principal component analysis which considers skewness and outliers effects was used to investigate the best portfolio diversification. Sixteen stock markets are represented with five components according to findings obtained from analysis. Hence Egyptian, Hungarian, Polish, Thai and Indonesian stock markets provide appealing portfolio diversification opportunities for investors of Turkey. And for the investors of USA and UK, selected emerging markets except Mexican and Turkish offer good diversification benefit.

Anahtar Kelimeler: Global portfolio diversification, Emerging markets, Outliers, Skewness, Robust principal component analysis.

Abstract

As a result of the contributions to science and technology made by humankind, intellectual ability has given rise to knowledge economy that increases the importance of intellectual capital. The development of intellectual capital in corporate dimension provides a competitive advantage and increases the market value of the firms. This study aims to examine whether or not the intellectual capital calculated according to the intangible assets method is reflected in the values that investors accord to firms in the ISE (Istanbul Stock Exchange) banking sector. A new model is developed in this study in order to overcome the limitations of the existing model in the literature. The results suggest that the intellectual capital is highly positively correlated with the market values. The correlation is even stronger for the new model developed in this study. As the importance of the intellectual capital in banking sector is relatively higher than other sectors, firms should give importance to the management of intellectual capital which is not reflected by the traditional accounting method. The intellectual capital should be calculated and reported to the concerned parties.

Keywords: Intellectual capital, Intangible Assets Method, Market Value, Banks, ISE

Özet

İnsanoğlunun entelektüel becerisinin bilim ve teknoloji alanlarına yapmış olduğu katkılar sonucunda bilgi ekonomisinin büyümesi, entelektüel sermayenin önemini artırmıştır. Entelektüel sermayenin işletme boyutunda geliştirilmesi, işletmelere rekabet üstünlüğü ve piyasa değerinde artış sağlamaktadır. Bu çalışma, maddi olmayan değer yöntemine göre hesaplanan entelektüel sermayenin, yatırımcılar tarafından işletmelerin piyasa değerine yansıtılıp yansıtılmadığını İMKB (İstanbul Menkul Kıymetler Borsası) banka sektöründe bulunan tüm işletmeler için araştırmaktadır. Bu çalışmada, literatürdeki mevcut modelde bulunan bazı kısıtlamalar, yeni bir yaklaşımla kısmen aşılarak yeni bir model geliştirilmiştir. Elde edilen sonuçlarda, özellikle bu çalışmada ortaya konan yeni modelin, işletmelere ait entelektüel sermaye değerlerinin piyasa değerleri ile yüksek düzeyde doğru orantılı ilişkili olduğu görülmüştür. Bankacılık sektöründe entelektüel sermayenin taşıdığı önemden dolayı, piyasa değerinin artırılmasında, işletmeler, mevcut muhasebede kayıt yöntemlerinde gösterilemeyen entelektüel sermayenin yönetilmesine özen göstermelidirler. Entelektüel sermayenin yönetilmesi için, öncelikle bu entelektüel sermaye tutarları düzenli olarak hesaplanıp raporlanmalı ve ilgililere sunulmalıdır.

Abstract

This study aims to make out-of-sample forecasts of recessions using the data of Turkey between 1986-2010. Recession forecast is important for decision makers in every level since it increases efficiency of decision making. Forecasting method used in this study is Qual-VAR method which includes information obtained from qualitative and/or discrete variables into vector autoregressions (VAR). Qual-VAR method makes it possible to create dynamic forecasts of qualitative variable using standard VAR projections. The evaluation and interpretation of findings obtained with this method are very simple. The findings obtained indicate that a recession will not occur during next twentyfour months in Turkey. However, we can expect that the probability of a recession will be increasing after 2014.

Keywords: Recessions, forecasting, Gibbs sampling, state-space models, Qual VAR models

Özet

Bu çalışmada, 1986-2010 dönemi verileri kullanılarak Türkiye’de durgunlukların örneklem dışı kestirimlerinin yapılması amaçlanmıştır. Her düzeydeki karar alıcılar açısından, durgunlukların kestirilmesi alınan kararların etkinliğini arttıracağından önemlidir. Kestirim tekniği olarak, kalitatif ve/veya kesikli değişkenlerden elde edilen bilgiyi vektör ardışık bağlanım (VAB) modeline dahil eden Kalitatif VAB yöntemi kullanılmıştır. Kalitatif VAB yöntemiyle, bilindik VAB modeli öngörülerinden hareketle durgunluk gibi kalitatif değişkenlerin dinamik kestirimleri yapılabilmektedir. Bu yöntemle ulaşılan bulguların yorumlanması ve değerlendirilmesi de oldukça kolay olmaktadır. Elde edilen bulgular, gelecek yirmi aylık dönem boyunca Türkiye’de bir durgunluk olayının meydana gelmeyeceğini göstermektedir. Bununla birlikte, 2014 sonrası dönemde bir durgunluğa girilmesi olasılığının artacağı beklenebilir.

Anahtar Kelimeler: Durgunluklar, kestirim, Gibbs örneklemesi, durum-uzay modelleri, Kalitatif VAB modelleri

Yeni ürün geliştirme, bir işletmenin faaliyetlerinde devamlılığı sağlamak açısından önemli bir konudur. Yeni ürünün pazara sürülmesi kararı, yeni ürünün maliyetine bağlı olarak verilmelidir. Özellikle, ürünün tasarım aşamasında tahmin edilen maliyeti, verilecek kararda etkili olmaktadır. Bu nedenle maliyet hesaplama ve yönetimine tasarım aşamasından başlanmalı ve ürünün ömrü süresince sürdürülmelidir. Hedef maliyet yöntemi, yeni ürünlerin tasarım aşamasında maliyetinin hesaplanmasında ve yönetiminde kullanılan bir maliyet yönetim aracıdır. Bu makalede, yeni ürün geliştirme süreci ve bu süreçte maliyetlerin nasıl hesaplanacağı incelenmektedir.

Abstract

Because of the increasing importance of effective and productive management of public organizations, budgetary slack is started to be seen as an important problem for public organizations. In order to contribute the solution of this problem, the current study investigates the effects of budgetary control effectiveness, ethical work climate and managers’ procedural justice perception on propensity to create budgetary slack in pubic organizations. The data is obtained through questionnaire responded by 465 managers who work in different public organizations. The results of the analyses show that effectiveness of budgetary control, ethical work climate and procedural justice perception of managers have a statistically significant and negative impact on managers’ propensity to create budgetary slack in public organizations. Budgetary control and ethical work climate affect managers’ perception of procedural justice. In addition, it is inferred from the study that the perception of procedural justice has partial mediation effect between effectiveness of budgetary control, ethical work climate and propensity to create budgetary slack.

Keywords: Budgetary slack, Budgetary control, Procedural justice, Ethical work climate, Public organizations.
