Business Ethics in Turkey: An Empirical Investigation with Special Emphasis on Gender

In today's complex business world, the question of business ethics is increasingly gaining importance as managers and employees face numerous ethical dilemmas in their jobs. The ethical climate in the Turkish business environment is also at a critical stage, and the business community as a whole is troubled by ethical problems. This study attempts to determine the effect of individual, managerial and organizational factors on the ethical judgments of Turkish managers, and to evaluate the ethical perceptions of these managers. The findings of this study reveal that the ethics score, the measure of ethical judgment, of Turkish managers differs significantly only with respect to gender and that female managers have higher ethics score than male managers. Other individual, managerial and organizational factors considered in this study do not have any significant effect on the ethical judgments of the managers. A comparative analysis between female and male managers in terms of their ranking of the eleven ethical business scenarios, ranking of the sixteen unethical acts, ranking of the factors influencing managers to engage in unethical practices, and ranking of the various parties to whom a company is socially responsible enables the researchers to enlighten the subject of business ethics in Turkey.     

A visualization system for mineral elasticity

The authors have developed an efficient visualization system to gain insight into large collections of mineral elasticity data produced by an increasing number of both theoretical calculations and experiments. The system allows us to visualize multivariate elastic moduli (i.e., elastic constant tensors) and their variation with composition, pressure and temperature. Moreover, it supports visualization of elastic wave propagation in an anisotropic medium by rendering the wave velocity data, which are calculated as a function of propagation direction in a three-dimensional space. This paper describes the design, implementation and application of the visualization scheme we have developed for mineral elasticity. In particular, our scheme exploits a combination of parallel coordinates, star plot, scatter plot and polygon-surface rendering techniques, which are implemented using OpenGL, GLUI and C++. The result is a highly portable and flexible interactive visualization system. For illustration, the elastic properties of several important oxide and silicate minerals are successfully visualized as a function of pressure and temperature.     

Options with Constant Underlying Elasticity in Strikes

Closed-form solutions are derived and interpreted for European options, with stochastic strike prices, that maintain constant elasticity of the strike with respect to the price of the underlying asset. We refer to such options as CUES. CUES preserve the relative shares of exercise price risk for both the buyer and writer of the option, regardless of whether the price of the underlying asset moves up or down. The relevance of the CUES concept is established through applications in two distinct fields. First, it is established that CUES-like options are embedded in private equity investments. This concept is then used in a novel application to determine the equity share of a private company corresponding to a given level of investment. Secondly, the advantages that CUES would provide over traditional executive stock option grants are considered and it is shown that CUES can provide enhanced incentive-alignment without increasing options expense to the company.

Signalling with official interest rates: the case of the German discount and lombard rate

A major characteristic of the operating procedure of the European Central Bank (ECB) is its reliance on standing facilities. It is intended that the official rates on those facilities also serve the function of signalling. The case of Germany, where the Bundesbank followed a similar signalling strategy, is analysed. In particular the paper investigates whether announcements of official interest rates provide information not already contained in other policy measures and whether the resulting revisions of expectations are efficient. Significant differences are found between signalling in the case of increasing and decreasing interest rates.     

The Internationalization of Small and Medium-Sized Firms

This paper contributes to the existing research by integrating the notions of organizational learning and entrepreneurial orientation into the body of international entrepreneurship. Our primary framework combines learning theory and the new venture theory of internationalization to study the extent to which small and medium-sized companies engage in international activities. We found that the firms’ international learning effort and entrepreneurial orientation are positively associated with internationalization intent whereas domestic learning effort is negatively related with internationalization intent. Overall, our results suggest (1) that intensive knowledge renewal and exploitation regarding foreign markets and the internationalization process itself may increase internationalization by affecting the perceptions of opportunities offered by further international expansion, and (2) that firms with an entrepreneurial mindset may be more likely to develop a long-term, substantial presence in the international arena, compared to firms that are more reactive or conservative.     

Institutions and economic growth in Portugal: a quantitative exploration

This paper presents a broad diagnostic of the level of institutional development in Portugal in the legal, corporate governance and financial systems. A comparative assessment suggests that Portuguese institutions are less developed than their European Union and East Asian counterparts, more developed than Greek institutions and on a level similar to that of Spanish institutions. We use data for a wide cross-section of countries since 1960 and correlate indicators of institutional development with the long-term average growth rate, identifying issues where reform is likely to significantly affect economic growth. We construct three new indices that measure the potential of institutional reform - the impact of reform on growth, the required reform effort and the efficiency of reform index - by taking into consideration the institutional distance between Portugal and the European Union. These indices measure, respectively, which reforms have the most payoff in terms of growth, which are less costly to undertake and which deliver the most growth per required effort. Our results strongly suggest that in a large number of issues, institutional reform may translate into substantially higher rates of economic growth. Of the ten most promising reforms, six are in the legal area, irrespective of which of the indices is considered. Whereas legal reform is promising at the aggregate and the microeconomic levels, in the financial sector aggregate indicators offer the wider scope for productive reform, while in the corporate governance area it is indices at the micro level that hold the most promise. These results support the view that a comprehensive reform effort is likely to deliver higher rates of growth in Portugal, allowing faster real convergence with the rest of the European Union.Received: January 2003, Accepted: February 2004, JEL Classification: O0, O5, K00, K4, G2, G3This paper is based on Firms, Financial Markets and the Law: Institutions and Economic Growth in Portugal, prepared for the conference Desenvolvimento Económico Português no Espaço Europeu: Determinantes e Políticas, organized by the Banco de Portugal.

Indirect exporters and importers

This paper analyses the relation between firms’ productivity and the different modes of participation in international trade. In particular, it accounts for the possibility that firms can not only export their products, but also internationally source their inputs, either directly or indirectly. Using a cross section of firm level data for several advanced and developing economies, the study confirms the productivity-sorting prediction according to which domestic firms are less efficient than those that resort to an export intermediary, while the latter are less productive than producers which export directly. We show that the same sorting exists on the import side. By considering firms involved in both exporting and importing activities, we also find that direct two-way traders are on average more productive than firms trading indirectly on one of the two trade sides. The latter are in turn more efficient than indirect two-way traders. Finally, we investigate the effects of source-country characteristics on the sorting of firms into different modes of international trade.     

Volatility in the knowledge economy

Summary. We seek to explain the economic volatility of the last 6 years, in particular the rapid expansion and contraction of the knowledge sectors. Our hypothesis is that these sectors amplify the business cycle due to their increasing returns to scale, growing faster than others in an upswing and contracting faster in a downswing. To test this hypothesis we postulate a general equilibrium model with two sectors: one with increasing returns that are external to the firm and endogenously determined - the knowledge sector - and the other with constant returns to scale. We introduce a new measure of volatility of output, a real beta, and derive a resolving equation, from which we prove that the increasing return sectors exhibit more volatility then other sectors. We validate the main results on US macro economic data of real GDP by industry (2-3 digits SIC codes) of the 1977-2001 period, and provide policy conclusions.Received: 18 March 2002, Revised: 16 February 2004, JEL Classification Numbers: D5, D58, E10, L50, L52, O38, O51.Correspondence to: Graciela Chichilnisky     

Chapter 11 and Asbestos: Encouraging Private Enterprise or Conspiring to Avoid Liability?

This paper explores the American bankruptcy system -- especially the Chapter 11 code -- which since 1978 has allowed insolvent companies the opportunity to restructure and reorganise with the benefit of court protection from creditors. Particular attention is focused on asbestos companies, such as Johns--Manville, which have been among the most consistent and controversial filers for bankruptcy under Chapter 11. The history of asbestos and Chapter 11 is explored, against the backdrop of the burgeoning asbestos crisis, caused by increasing mortality and litigation. Some of the business and ethical issues involved are highlighted by examining in detail a recent bankruptcy (Federal Mogul/T&N in 2001) that has implications in both Britain and America. Chapter 11 bankruptcy is evaluated, particularly in the light of the trend towards similar mechanisms of insolvency in the UK, Europe and the rest of the world. It is concluded that, certainly as regards the experience with asbestos, Chapter 11 offers an inefficient and inequitable method of rehabilitating or rescuing failing businesses.
