Relative underperformance Alla Turca

From 1960 to 2003, Turkey has underperformed relative to several Western economies, in terms of hours worked and output per hour. Our sectoral analysis illustrates two points. First, Turkey's large drop in hours is due to the fact that the substantial decline in agricultural hours has not been accompanied by a corresponding increase in nonagricultural market hours. Second, the sectoral composition of output is important for understanding Turkey's relatively weak rise in output per hour. We develop a simple model of structural transformation and home production to provide an account of Turkey's performance relative to the U.S. and Southern Europe. We find that the evolution of exogenous differences in sectoral productivity and taxes, between Turkey and the U.S., as well as Southern Europe, can account quantitatively for most of Turkey's relative underperformance to these regions.     

GOVERNANCE INSTITUTIONS AND PRIVATE INVESTMENT: AN APPLICATION TO THE MIDDLE EAST AND NORTH AFRICA

This paper addresses the issue of the low level of private investment in the Middle East and North Africa (MENA) region, with special emphasis on the role of governance. Based on the existing published reports, we categorize what types of governance institutions are more detrimental to entrepreneurial investments. We then estimate a simultaneous model of private investment and governance quality where economic policies concurrently explain both variables. Our empirical results show that governance plays a significant role in private investment decisions. This result is particularly true in the case of “administrative quality” in the form of control of corruption, bureaucratic quality, investment‐friendly profile of administration, law and order, as well as for “political stability.” Evidence in favor of “public accountability” is also found. Our estimations also stress that structural reforms like financial development, trade openness, and human development affect private‐investment decisions directly, and/or through their positive effect on governance.     

Information asymmetry, speculation and foreign trading activity: Emerging market evidence

This paper provides evidence on the relation between private-information-based trading and foreign trading activity on the Istanbul Stock Exchange (ISE). We use a recently developed model that utilizes information in volume-return dynamics of individual stocks and show that variables such as size and Tobin's Q explain the extent of speculative activity across firms traded on the ISE. We present evidence supporting the notion that foreign trading activity is associated with informed trading on the ISE. Implications of our findings for emerging markets research are also discussed.     

Macroeconomic Drivers of Loan Quality in Turkey

We analyze the drivers of nonperforming loans in the Turkish banking system after the 2000–01 Turkish banking crisis. By constructing a vector autoregression model, we perform dynamic out-of-sample forecasts, which yield quite accurate results compared to the actual data. Since forecasting is a very crucial tool for both policy makers and market players, these results are some of the main strengths and contributions of this study. This article shows various patterns between the economic and financial indicators and the nonperforming loans. One important message obtained from the results is that policy makers should be concerned about the status of the economy and the market expectations to maintain stability in the banking system.     

Overcoming the psychological barriers to energy conservation behaviour: The influence of objective and subjective environmental knowledge

Energy conservation is a crucial aspect of responsible consumption which is the reflection of individual efforts for sustainability. However, especially young consumers are reluctant to reduce their energy consumption despite their pro‐environmental attitudes. Resistance to behavioural change can be attributed to various psychological barriers that help consumer to avoid engaging in pro‐environmental actions. In this context, the first aim of the study is to extend the theoretical and empirical evidence regarding impeding effects of psychological barriers on individual energy conservation behaviour. Secondly, the study investigates the alleviating role of environmental knowledge on those barriers that limit energy conservation. Proposed impeding effects of objective and subjective environmental knowledge on various denial mechanisms, which are in turn expected to hinder energy conservation, were tested using the survey data collected from young Turkish consumers. Results suggest that denial mechanisms hinder young consumers’ energy conservation behaviour indirectly through diminishing feelings of moral obligations. Moreover, it was found that objective environmental knowledge's effect can be used to break down the psychological barriers and to facilitate the change towards more sustainable energy consumption patterns. Implications of the findings and directions for future research are discussed.     

How Ethical Behavior of Firms is Influenced by the Legal and Political Environments: A Bayesian Causal Map Analysis Based on Stages of Development

Even though potential impacts of political and legal environments of business on ethical behavior of firms (EBOF) have been conceptually recognized, not much evidence (i.e., empirical work) has been produced to clarify their role. In this paper, using Bayesian causal maps (BCMs) methodology, relationships between legal and political environments of business and EBOF are investigated. The unique design of our study allows us to analyze these relationships based on the stages of development in 92 countries around the world. The EBOF models structured through BCMs are used to explain how EBOF in a given country group are shaped by how managers perceive political, legislative, and protective environments of business in these countries. The results suggest that irregular payments and bribes are the most influential factors affecting managers’ perceptions of business ethics in relatively more advanced economies, whereas intellectual property protection is the most influential factor affecting managers’ perceptions of business ethics in less-advanced economies. The results also suggest that regardless of where the business is conducted in the world, judicial independence is the driving force behind managers’ perceptions of business ethics. In addition, the results of this study provide further support for scholars who argue that business ethics is likely to vary among countries based on their socio-economic factors. In addition to its managerial implications, the study provides directions for policy makers to improve the ethical conduct of businesses in their respective countries.     

Demand shocks,supply shocks and the cyclicality of real wages

The behaviour of real wages over the business cycle has received increasiing attention in recent years. The cyclicality of real wages constitues an important aspect of recent models of the business cycle. However,empirical studies undertaken to determine whether real wages are procyclical or countercyclical have reported conflicting findings. In thiis paper we use vector-autoregressions to analyse the cyclicality of real wages. We find that the source of the disturbance plays a decisive role in the cyclical behaviour of real wages. In particular, we demonstrate that a supply shock generates procyclical real wages,whereas a demand shock yields countercyclicality.     

Product differentiation and welfare: Comment

In general it may be argued that the monopolistically competitive industry is not consistent as viewed from the game-theoretic point of view, and it ignores the strategic aspects of competition. This comment points out specifically how the welfare implications derived from a Nash equilibrium model in which the goods are imperfectly substitutes used by Spence in many articles are incorrect. The total quantities offered by firms at Nash equilibria within this model and those of the market demand curve at the same price levels are not equal. All emanate from the misspecification of the price equation with substitutable goods by Spence which is not appropriate for the Nash equilibria model with many firms. Moreover, some other very important papers of Spence which follow are critisized for the same mathematical contradiction.     

An applied stochastic model of the quality–quantity trade-off in the public health care sector

It is a striking feature of the many of the developing country public service sectors that the sectors in question often overproduce the quantity of services but underproduce the quality. This feature, which is exemplified in this paper, is rooted in a wide spectrum of economic and sociological factors ranging from the economic and sociological profile of the service receiving people to the asymmetric density of service-receiving population across their regions. This feature, we conjecture, is a source of a considerable degree of suboptimality in some of the developing countries. If our conjecture is correct, correcting such suboptimalities is likely to yield significant welfare improvements that could help speed up the process of development in the underdeveloped regions of the world. To analyze the supoopimalites in question, we will first develop a concept (and a model) of optimal quality in the public service sector, which indicates the level of quality that maximizes expected public satisfaction subject to available resources. Resources are used in an efficient manner to produce the service in question. The concept and the model in the paper make a needed contribution to the quality discourse by presenting a way of determining the quality improvements (or adjustments) necessary to achieve optimum in the public service sector. The paper presents an application (a case study) of this new concept in the public healthcare sector in Turkey, and explores the differences between the actual and optimal quality in the sector in question. It turns out that there is a considerable difference between the actual and optimal levels of quality (as well as those of quantity) in the Turkish public healthcare sector in an overpopulated city (Istanbul), indicating a significant overproduction of quantity and underproduction of quality. Thus, to achieve the optimal levels, the sector should increase quality and reduce quantity by a considerable margin. The quantified differences (gaps) between actual and optimal levels point out a considerable room for welfare improvement. Optimum-seeking adjustments closing these gaps could be shown to lead to considerable satisfaction and welfare gains, the measurement of which is worthy of future research.
