Efficiency in Turkish banking: post-restructuring evidence

Turkish banking sector went through a significant restructuring process in the aftermath of the country's financial crisis of 2000–2001. In this paper, we analyze the evolution of banking performance using a novel approach due to Ray [(2007). “Shadow Profit Maximization and a Measure of Overall Inefficiency.” Journal of Productivity Analysis 27, 231–236]. We derive ‘shadow unrealized profit scores’ as well as ‘shadow input–output prices’ for each year and bank in the sector from 2002 to 2011. We argue these scores operationalize the Hicksian concept of ‘monopolistic quiet life’. We provide some evidence the sector came closer to the ‘zero profit condition’ as well as displaying a closer approximation to the ‘law of one price’ over time. We show the variability of these ‘shadow prices’ essentially coincides with that of corresponding actual prices. We utilize shadow price information to show that business models and competitive choices of banks differ across ownership types with foreign banks competing on the broadest front compared to state-owned and privately owned Turkish banks.     

Revenue management for make-to-order manufacturing systems with a real-life application

Abstract

Due to successful applications of revenue management in the airline industry, in recent years, there has been a growing interest to adopt revenue management in make-to-order (MTO) manufacturing systems. Several interrelated decision problems such as order acceptance/rejection, short-term capacity planning, due date assignment, and order scheduling need to be studied simultaneously in order to manage revenues effectively in MTO manufacturing systems. Both the producer’s and customer’s requirements need to be taken into account through some negotiation mechanisms that are sensitive to the service-level reputation of the manufacturing companies. In this article, we propose a new dynamic bid price–based revenue management model that considers all of the aforementioned decision problems simultaneously. A simulation optimization approach is utilized in order to determine the best possible values of control parameters for bid price, due date assignment, and price increment/reduction mechanisms. The performance of the proposed integrated revenue management model is tested on both a hypothetical example and a real problem of a bridal gown company. The computational results show that the proposed model provides significant improvements in total revenue compared to other static and dynamic bid price policies.     

Do Low Wages Stimulate Investment? An analysis of the relationship between distribution and investment in Turkish private manufacturing industry

This study analyses the relative impact of profitability and demand on accumulation in Turkish private manufacturing industry on the basis of the theoretical framework outlined by Marglin & Bhaduri (1990). The main motivation behind this analysis is to shed light on the demand aspects of the slowdown in accumulation in the manufacturing industry despite the increase in profitability during the structural adjustment episode. For this purpose, the ratio of investment to value-added is estimated as a function of the profit share and an accelerator term, namely the growth rate of value-added, using panel data for the 26 industries of the private manufacturing sector. The results show that investment is not responsive to the profit share, whereas growth has a consistent positive impact. This result is significant in explaining the inability of pro-capital income policies to stimulate manufacturing investments throughout the export-promotion era. The export boom maintained by the use of the existing capacity rather than by new investments shows the limits of export demand to compensate for the fall in domestic consumption out of wages. The results make a strong case against the argument that profitability enhances accumulation. Evidence shows that it is not possible to enhance accumulation and long-term potential for growth simply based on promoting profitability, without paying attention to the demand aspects.     

An application of data envelopment analysis to the evaluation of audit risk: a reinterpretation

This paper, which reinterprets previous work by Bradbury and Rouse (2002 ), addresses the risk quantification issue at an intuitive level. The insights provided by such quantification are discussed. Risk factors are associated with the risk-return concept. This allows measuring whether risks taken on are appropriately rewarded. The paper gives a non-technical exposition of DEA and outlines possible applications to accounting and finance. Using data for a large multinational, it shows how DEA analysis can be combined with internal audit procedures. It explains how the results obtained can be used to improve risk management.     

Determinants of Saving-Borrowing Decisions and Financial Inclusion in a High Middle Income Country: The Turkish Case

We use a representative survey of the Turkish household sector and investigate factors impinging on saving-borrowing behavior. We run four probit regressions to elucidate (i) the saving decision, (ii) asset choice or portfolio composition for those who save, (iii) the bank loan decision and lastly (iv) the formal versus informal borrowing decision. We find income, education, marital status and region within country strongly correlate with those decisions. We offer some insights regarding the influence of variables like rural to urban migrant status and religious belief on saving and borrowing decisions. We discuss the long-term implications of our findings on the Turkish household savings performance.     

Assessing the efficiency of Turkish secondary education: Heterogeneity, centralization, and scale diseconomies

This paper begins with a historical overview of the Turkish educational system. We then use Data Envelopment Analysis (DEA) and econometric methods to evaluate the system's efficiency. In doing so we identify scale diseconomies and relate them to underlying structural characteristics of the system. Selected suggestions on improving performance are offered. The roles of heterogeneity and centralization are also highlighted. Heterogeneity is modeled as an undesirable measure. The linkage between indicators of centralization and scale diseconomies was found to be statistically significant. The authors believe this to be the first study that investigates the impact of systemic characteristics such as heterogeneity and centralized structure on educational outcomes for Turkey. Since the country straddles the Middle East and the Balkans, culturally as well as geographically, it may be of interest to other countries in the region.     

Impacts of capital inflows on aggregate spending categories: the case of Turkey

This paper discusses the impact of foreign savings on aggregate spending categories in Turkey. Using the vector autoregressive (VAR) models the major finding is that foreign savings has an increasing effect on consumption. The increase of investment arises from the accelerator effect of consumption, which results in an upward trend in investment in non-tradable sectors. Concluding that the policy of relying on foreign savings, to obtain long-term increases in tradable sector investment and competitiveness is ill-judged.     

Measuring the quality of hospitality at Antalya

Tourism has become an important pillar of the Turkish economy. Therefore, service quality of the catering sector deserves and attracts attention. This paper employs data envelopment analysis (DEA), a linear programming method, to gauge the validity of official quality ratings at Antalya, a major seaside resort. This benchmarking‐based technique is applied to standardise the ‘starring’ system used by regulators and rating agencies. This is done by using efficiency scores generated by the DEA technique. Such standardisation helps tourists and tour operators. In addition, a second‐stage Tobit regression identifies the causes of inefficiency, and the managerial implications of the findings are discussed. Copyright © 2007 John Wiley & Sons, Ltd.
