Sequencing in telecommunications reform: A review of the Turkish case

This paper reviews the Turkish case of telecommunications reform with reference to the evidence from the sequencing literature. Turkey’s progress is in line with the proper sequencing of reform suggested by the literature. Accordingly, Turkey has pursued a gradualist approach by restructuring its public utility, the Posts, Telegraph and Telephone Company, and creating Turk Telecom in 1994; establishing the sector regulator, the Turkish Telecommunications Authority, in 2000; and liberalising the sector in 2003 before selling 55% of Turk Telecom to Oger Telecom, a private company, in 2005. Although the proper sequencing of reform was implemented, the Turkish telecommunications sector has not been functioning satisfactorily as yet, as indicated in the recent progress report of the European Union about Turkey’s accession and as revealed by the performance indicators analysed in this paper. The prevailing information, incentive and commitment problems require a close cooperation by the government with the regulators so as to ensure and reinforce the autonomy of the Telecommunications Authority and to establish a more transparent decision-making process.     

Characteristics of innovating firms in Tunisia: The essential role of external knowledge sources

This article is dedicated to the analysis of the first innovation survey of the Tunisian firms. Starting from basic mechanisms of innovation processes and existing results on other developing countries, we test a set of assumptions on the characteristics of innovating firms in a developing country like Tunisia. The analysis of product and process innovations shows the essential role played by external technical knowledge sources: firms must be able to benefit at least from one such a source in order to attain a significant innovation propensity. We also show that the profile of Tunisian firms can be contrasted with other developing countries. The main contrast concerns the limited role of internal R&D and the insignificant role played by foreign participation. For both types of innovations, another important contrasting result concerns the role of sectoral membership. In Tunisia, this dimension does not seem to structure enough systematically the innovative capabilities of firms. That could indicate an immaturity of sectoral systems of innovations in this country.     

Public Education and Intergenerational Economic Mobility

This paper examines the role of public education in determining intergenerational economic mobility. It considers a model in which education is free and admission to schools is competitive. The results indicate that for mobility to increase during the process of development, the share of resources devoted to public education needs to be large enough to offset the relative advantage of having educated parents in academic attainment.     

The trade paradox persists under excise taxes

Brander and Krugman (1983) and Sertel (1988) followed by Krugman (1989), showed two sides of a ‘trade paradox’: The paradox in competition, viz. that opening trade (or increasing competition) may cause welfare to decline, and the paradox in efficiency, viz. that an increase in unit transport cost may increase welfare. In this paper, we consider the situation in an environment where interventionist trade policies are not permitted but each country is sovereign to impose an excise tax (or subsidy). The paradoxes persist under equilibrium excise taxes, reckoned both at the non-cooperative (Nash or dominant strategy) equilibrium and at the cooperative solution among tax-imposing authorities maximizing welfare. We also see that the paradoxes persist in a taxless environment where market equilibrium is Stackelberg rather than Cournot.     

Workers' enterprises in price competition

Extending earlier equivalence results for perfect competition and for (imperfect) quantity competition, here it is shown that in price competition, too, the behavior of a workers‘ enterprise (defined by the coincidence of its workers with its partners) is tamed by the worker-partnership market so as to be identical with that of a twin entrepreneurial firm. Thus, not only is Bertrand–Nash equilibrium unaltered when an entrepreneurial firm is replaced by its workers’ enterprise twin, but such a replacement also leaves Bertrand-von Stackelberg equilibrium intact whether we switch the leader or a follower from one form of ownership/management to the other.     

Managing Capacity in the High-Tech Industry: A Review of Literature

This article surveys a new generation of analytical tools for capacity planning and management, especially in high-tech industries such as semiconductors, electronics and bio-techs. The objectives of the article are to (1) identify fundamental theory driving current research in capacity management, (2) review emerging models in operations research, game theory, and economics that address strategic, tactical and operational decision models for high-tech capacity management, and (3) take an in-depth look at capacity-optimization models developed in the specific context of semiconductor manufacturing. The goal of this survey is to go beyond typical production-planning and capacity-management literature and to examine research that can potentially broaden capacity-planning research. For instance, we explore the role of option theory and real options in modeling capacity decisions. We not only examine capacity-planning problems from the perspective of a particular firm, but also the interaction of capacity investment among supply chain partners. Not only are these issues increasingly important in the fast-changing high-tech environment, they draw on new tools from different disciplines and pose significant intellectual challenges. We also examine papers that represent the multifaceted nature of high-tech capacity planning, integrating capacity decisions with issues related to contracting, coordination, sourcing, and capacity configurations.     

The Real Exchange Rate and the Structural Transformation(s) of China and the U.S.

From 1989 to 2010, the RMB–dollar real exchange rate depreciated, despite China's rapid income growth relative to the US. We develop a macroeconomic-trade model of the very long-run equilibrium RMB-dollar real exchange rate. We show that this long-run depreciation of the RMB-dollar real exchange rate can be justified by our model, if we note that Chinese agriculture has relatively low productivity and that agriculture is tradeable. Relative to our equilibrium benchmark, the current real RMB-dollar rate is, if anything, over appreciated.     

The effect of ethical leadership on service sabotage

ABSTRACT

This study aims at examining the impact of ethical leadership activities on service sabotage, and the mediating role of service climate and corporate ethical values (CEV) on this impact. The study was completed via 384 acceptable questionnaires in total. The research findings show that ethical leadership affects the service climate and the CEV in a positive way whereas it has a negative effect on the service sabotage. In addition, it is observed that the CEV have a positive effect on the service climate. In the light of the research findings, managers’ ethical personal and managerial characteristics affect the service climate in a positive way and play a significant role for the ethical values to become more common within the organization. Furthermore, the ethical leadership is effective for decreasing the service sabotage which is referred as the undesirable and harming behaviors within the organization.     

Performance evaluation using data envelopment analysis in the presence of time lags

Data Envelopment Analysis (DEA) is a methodology that computes efficiency values for decision making units (DMU) in a given period by comparing the outputs with the inputs. In many applications, inputs and outputs of DMUs are monitored over time. There might be a time lag between the consumption of inputs and the production of outputs. We develop an approach that aims to capture the time lag between the outputs and the inputs in assigning the efficiency values to DMUs. We propose using weight restrictions in conjunction with the model. Our computational results on randomly generated problems demonstrate that the developed approach works well under a large variety of experimental conditions. We also apply our approach on a real data set to evaluate research institutions.     

Incentives for Technology Adoption Under Environmental Policy Uncertainty: Implications for Green Payment Programs

Water quality protection policy in the UnitedStates has been based on the provision offinancial incentives to farmers for adoptingimproved nutrient management practices.Increasing reliance on subsidy programs couldresult in expectations for such programs in thefuture. Using an option-value model thatindicates uncertainty can lead to a delay ininvestment, this paper analyzes the extent towhich uncertainty about cost-share subsidypolicies would impact adoption decision.Application of the model to adoption ofsite-specific technologies indicates thatuncertainty about subsidy policies has thepotential to impact the investment decision.When there is currently no cost-share subsidy,an increase in the probability of an expectedpolicy delays adoption. If the policy is ineffect, an increase in the probability of awithdrawal of the program encouragesinvestment. Cost-share subsidy policy is mosteffective when it is immediately offered andguaranteed that it will be removed soon.
