The Buyer–Supplier Relationship: An Integrative Model of Ethics and Trust

Dialogues between companies and actors of society often start as a result of a public scandal or in a situation of crisis. They can lead to short-term public relations activism or to long-term reputation gains. On the basis of cases and of a typology of forms of dialogues, the author develops ethical criteria and conditions for a successful dialogue – the ethical basis for such criteria being values such as equality, freedom and participation. A special focus is put on challenges that often result from dialogues such as the ethical judgment of compromises. This article proposes ethical criteria to evaluate compromises. This leads to a model of ethical dialogue.     

政府规模、市场化与地区腐败

Using a panel data at the provincial level during the period of 1989–2004, this paper examines the effects of social and economic factors such as government scale, privatization, openness, and education on regional corruption. Applying a fixed-effect model and IV estimation, we find that government size positively affects the incidence rate of corruption, and the effect becomes larger with the increase in the size of the core department of the government. 1% increase in the core department of the government leads to a 0.68%–1% increase in the number of corruption cases. While the proportion of FDI is positively associated with the corruption of regional officials, the ratio of the import and export trade to GDP is negatively associated with corruption. The impact of privatization on corruption is ambiguous. We also identify the significant impacts of the size and structure of the government expenditure on corruption. __________ Translated from Jingji Yanjiu 经济研究 (Economic Research Journal), 2008, (11): 16–26     

Work Values of Turkish and American University Students

The first aim of this paper was to investigate how the traditional Protestant work ethic (PWE) and more contemporary work values (i.e., masculine, feminine, and entrepreneurship values) were related to one another, and differed across genders and two cultural contexts, namely Turkey and the U.S. The second aim was to elucidate the role of religiosity in PWE among the two cultural groups. Two hundred and sixty six American and 211 Turkish university students participated in this questionnaire study. The analyses examining cross-cultural differences revealed that Turkish university students reported greater scores in the PWE and all contemporary work values as compared to their American counterparts. For the Turkish sample, there were no gender-related differences in the PWE, whereas in the U.S. sample, men reported greater PWE scores than did women. With regard to gender differences in contemporary work values, our results showed that gender groups differed in feminine and entrepreneurship values in both cultural contexts; men emphasized femininity and entrepreneurship more than women in Turkey but the reverse was true in the U.S. Correlations between contemporary work values and the PWE illustrated that the PWE is associated with entrepreneurship and masculine values in both cultural contexts and with feminine values in the Turkish context. Finally, our results regarding the role of religiosity in PWE indicated that highly religious participants reported greater PWE scores than the less religious ones regardless of culture. Findings are discussed with reference both to differences in the two socio-cultural contexts and to recent change in the social structure of Turkish society.

A New Approach to Gravity Anomaly Separation: Differential Markov Random Field (DMRF)

In this paper the authors introduce a novel approach to stochastic image processing, denoted as Differential Markov Random Field (DMRF), which has been applied to gravity anomaly separation problems. The advantages of the method are that it introduces only little distortion into the shape of the original image and that it is not affected significantly by factors such as the overlap power spectra of regional and residual fields. Testing of the proposed meth using synthetic examples gave excellent results.     

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.     

Career success schemas and their contextual embeddedness: A comparative configurational perspective

We introduce career success schemas as critical for understanding how people in different contexts perceive and understand career success. Using a comparative configurational approach, we show, in a study of 13 countries, that two structural characteristics of career success schemas—complexity and convergence—differ across country contexts and are embedded in specific configurations of institutional factors. Adopting complexity and convergence as primary dimensions, we propose a taxonomy of career success schemas at the country level. Based on this taxonomy, we contribute to the understanding of subjective career success across countries, discuss the importance of schemas for organisational career systems in multinational enterprises, and propose specific guidelines for future comparative careers research.     

A STRUCTURAL MODEL OF ELECTORAL ACCOUNTABILITY

This article proposes a structural approach to measuring the effects of electoral accountability. We estimate a political agency model with imperfect information in order to identify and quantify discipline and selection effects, using data on U.S. governors. We find that the possibility of reelection provides a significant incentive for incumbents to exert effort, that is, a disciplining effect. We also find a positive but weaker selection effect. According to our model, the widely used two‐term regime improves voter welfare by 4.2% compared to a one‐term regime, and better voter information about the effort of the governors would further increase voter welfare by up to 0.5%.     

Economic growth and carbon emissions: evidence from CIVETS countries

ABSTRACT

This paper examines whether a long-run relationship exists between CO₂ emissions and selected variables: real gross domestic product per capita, inward stock of foreign direct investments, gross fixed capital formation, industry, value added and energy use per capita for Colombia, Indonesia, Viet Nam, Egypt, Turkey and South Africa countries in the period of 1989–2016. We used panel unit root testing, followed by panel cointegration tests and panel causality. The results clearly prove the existence of a bidirectional long-run causal relationship between all the variables except between CO₂ emissions and GDP and CO₂ emissions and GFCF. Major finding of the short-run causality analysis is that CO₂ emission in the short run does not result in changes of other variables. On the other hand, all variables except foreign direct investments (FDI) cause the changes in the CO₂ emissions, and there is a positive bidirectional causal relationship between GDP and FDI, between GFCF and FDI, and between GFCF and IVA. Finally, positive unidirectional causal relationship also exists, running from GDP to IVA, GDP to ENUSE, IVA to FDI and ENUSE to FDI.     

Is ‘oil and gas’ industry of ASEAN5 countries integrated with the US counterpart?

ABSTRACT

This paper employs the VARMA-MGARCH-ABEKK model and Granger causality on 15 years’ daily time series data to examine investment opportunities in the oil and gas industries for ASEAN5 countries relative to the US counterpart. It shows that the latter leads the former in decomposing integration into cross-country effects on returns and conditional return volatilities. The empirical results show that investors can gain an international intra-industry diversification benefit in Malaysia, the Philippines, Singapore and Vietnam by holding US oil and gas assets in their portfolios whereas Asian oil and gas assets may result in negative shocks due to the increase in return volatilities for Malaysia, Singapore and Vietnam. However, Thailand are insensitive to the cross-country intra-industry diversification. While making trading decisions, investors should be aware of the impulse responses of ASEAN oil and gas markets from the shocks in the US and the Asian markets and their asymmetric spill over effects.     

Order anticipation around predictable trades

I study the presence of order anticipation strategies by examining predictable patterns in large order trades. I construct three simple signals based on child-order execution patterns and find empirical evidence that stronger signals are correlated with higher execution costs. I use the SEC's (Securities and Exchange Commission's) ban on unfiltered access and increase in noise trading as shocks to order anticipatory activities of algorithmic traders and find that the price impact of predictability is smaller when order anticipation becomes difficult. The empirical findings are mostly consistent with the back-running theory that predicts delayed price impact as strategic traders learn about large orders gradually.
