Turnover, Ownership and Productivity in Malaysian Manufacturing
(Routledge Journals, Taylor & Francis Ltd, 2013) Dogan, Ergun; Wong, Koi Nyen; Yap, Michael M. C.
Applying Foster, Haltiwanger, and Krizan's decomposition of productivity growth method to Malaysian manufacturing census data for 2000 and 2005, we analyze if firm turnover by ownership (domestic vs. foreign) has any impact on the sector's aggregate productivity growth. The findings show that turnover matters regardless of ownership, but more importantly, attracting foreign direct investment inflows could induce positive net entry effect'. The analysis shows that large-sized foreign and domestic entrants are more productive than medium-sized and especially small-sized ones. The study provides important implications for government policies based on ownership and firm size.
The Journal Forum: 1954-1960 in Turkey
(Common Ground Research Networks, 2007) Cakmak, D.
In the ten years (1950-1960) of Democrat Party rule in Turkey, intellectuals were obliged to create some alternative centers of power, particularly in view of government's oppressive policies towards the universities and the press. Forum Journal constituted one such center of criticism. Forum's writers -most of whom were educated in the republican regime- opposed the DP's pragmatic approach to politics and wanted to center political life on reason and to eliminate conservative attitudes. Most of the writers were from the Faculty of Political Science in Ankara University. Forum started to be published in April 1954. Forum did not aim at a struggle to acquire political power. Forum had an influence on almost the whole of the Turkish intelligentsia in the years 1954-1960. The institutions and ideas suggested by Forum were realized to a large extent with the Constitution accepted after the military intervention in the year 1960. For example, the establishment of a second chamber of the legislative assmebly -the Senate-, the constitutional court, the state planning organization, autonomous universities, independence of judges, free press, granting rights to strike and collective negotiations to workers, free opposition, the principal of social equality..etc that had all been discussed in the pages of Forum, found place in the Constitution 1961. So it is possible to claim that Forum Journal with its great contribution for the reconsolidation of the democratic regime demonstrated the higly significant role in Turkish political life. Forum writers treated the military intervention in 27 May 1960 as the liberator of Turkish democracy although it caused a temporary break in the democratic regime. This study which is based on the evaluation of Forum Journal will be a serious contribution considering the journal's support in military intervention of 1960 in Turkish political life. © Common Ground, Diren Cakmak, All Rights Reserved.

Distinct Asymmetric Effects of Military Spending on Economic Growth for Different Income Groups of Countries
(Taylor & Francis Ltd, 2023) Ocal, Nadir; Yildirim, Julide; Karadam, Duygu Yolcu
Although possible asymmetries for univariate and multivariate dynamics have been the focus of interest in many areas of economic explorations, it seems that most of the research on military expenditure - economic growth nexus has tended to assume linear relationships. This paper aims to examine possible nonlinearities in military expenditure-economic growth nexus employing data for a sample of 103 countries covering the 1988-2019 period. For this purpose, Panel Smooth Transition Regression, PSTR, models are estimated not only for all countries' sample but also for low income, middle income, and high-income countries' subsamples to reveal possible distinct asymmetric relationships for country groups with different income levels. Empirical results for the whole sample, low income and middle income groups indicate that military expenditure not only governs the regime change, but also low and high levels of military expenditure have distinctive and rising negative effects on economic growth with dissimilar threshold effects. Moreover, empirical findings also indicate that net arms exports govern regime change for high income countries, and as net arms exports rise, the negative impacts of military expenditure on economic growth become deeper.

The Effects of Federal Regulations on Corruption in Us States
(Elsevier Science inc, 2020) Gunalp, Burak; Dincer, Oguzhan
Using the newly constructed Federal Regulation and State Enterprise Index (FRASE Index) to measure the federal regulations and the existing Corruption Convictions Index (CCI), we investigate the effects of federal regulations on corruption in U.S. states. Controlling for several demographic and economic variables including the Fraser Institute's Economic Freedom Index (EFI), which measures the size and scope of government in U.S. states, we find a positive and statistically significant relationship between federal regulations and corruption. Our findings have important policy implications. A 1 standard deviation increase in FRASE Index causes CCI to increase by approximately 0.5 standard deviations. Standardized coefficient of EFI is also approximately equal to 0.5. In other words, it is possible to mitigate the effects of regulations at the federal level by reducing the size and the scope of the government at the state level.

Transportation-Communication Capital and Economic Growth: a Vecm Analysis for Turkey
(Routledge Journals, Taylor & Francis Ltd, 2012) Eruygur, Aysegul; Kaynak, Muhtesem; Mert, Merter
This paper analyses the short- and long-term relationships between the transportation-communication capital and the output for Turkey. The study applies a Cobb-Douglas production function under the assumption of constant returns to scale and employs co-integration analysis by estimating a vector error correction model (VECM). As a result of the VECM estimation, one co-integrating relationship is detected. The results based on the impulse response function analysis imply that per labour transportation-communication capital appears both to have been a crucial input in the Turkish productive process and to have had a positive crowding in effect on the per labour non-residential total capital formation. Moreover, the results support the argument that the transportation-communication capital has a lagged impact on economic growth. The long-term accumulated elasticity of output to transportation-communication capital has been found to be 0.59. The long-term accumulated marginal product was also calculated. It implies that a 1 Turkish Lira increase in per labour transportation-communication capital results in a long-term rise of 1.45 Turkish Liras in per labour output. All these findings suggest that transportation-communication capital may be a powerful tool for policy-makers to promote long-term per labour real output growth in Turkey.

Analysis of Distinct Asymmetries in Financialintegration-Growthnexus for Industrial, Emerging and Developing Countries
(Wiley, 2022) Ocal, Nadir; Yolcu Karadam, Duygu
This paper examines the threshold conditions in financial integration and growth relationship for a large set of threshold variables and different income group of countries employing Panel Smooth Transition Regression Models. Except developing countries, our findings strongly indicate nonlinear dynamics and imply that the impact of financial integration on growth is asymmetric depending on a number of indicators such as countries' degree of institutional quality, financial sector development, trade openness, budget deficit, inflation volatility and the level of financial integration. Our results show that these threshold effects substantially differ for emerging and industrial countries. As far as whole set of countries is concerned, our findings imply that countries having developed financial systems, qualified institutions and stable macroeconomic environment benefit from financial integration. Moreover, threshold effects are stronger and different for emerging countries compared to the industrial countries. Unlike emerging economies, higher levels of financial integration and trade openness decrease benefits from financial openness for the industrial countries. Besides, high fiscal deficit has more pronounced negative effect on the growth of the industrialized countries compared to emerging economies and other indicators.

Inflation and Growth: an Empirical Study for the Comparison of the Level and the Variability Effects
(Nova Science Publishers, Inc., 2006) Arin, K.P.; Omay, Tolga; Omay, T.; Çankaya Meslek Yüksekokulu
This paper analyzes the interaction between the inflation and growth within the Mankiw-Romer-Weil (1992) framework. Our results indicate that the inflation level has a significant negative effect on output in advanced capitalist economies, whereas inflation variability has a negative and significant effect on output in the long-run for all sub-samples. Our results also show that the variability effects are larger in terms of significance. © 2006 Nova Science Publishers, Inc. All rights reserved.
Multiple linear regression model under nonnormality
(2004) Islam, M. Qamarul; Tiku, Moti L.
We consider multiple linear regression models under nonnormality. We derive modified maximum likelihood estimators (MMLEs) of the parameters and show that they are efficient and robust. We show that the least squares esimators are considerably less efficient. We compare the efficiencies of the MMLEs and the M estimators for symmetric distributions and show that, for plausible alternatives to an assumed distribution, the former are more efficient. We provide real-life examples.
Is there convergence in renewable energy deployment? Evidence from a new panel unit root test with smooth and sharp structural breaks
(2023) Çorakçı, Ayşegül; Omay, Tolga
This study examines whether the contribution of renewable energy to the total primary energy supply converges in a panel of 24 OECD countries over the period 1960–2020. To this end, a new panel unit root test that allows for both sharp and smooth breaks is proposed to test for the stochastic convergence hypothesis. Although renewable energy convergence is not rejected when the newly proposed test is applied to the full panel of OECD countries, it found only moderate support within the members of the panel using a sequential panel selection methodology. In fact, in two high-income OECD countries, the contribution of renewable energy to the primary energy supply shows no sign of convergence: Poland and Iceland. Therefore, the renewable energy shares seem to be converging to a common steady state in only a group of OECD countries over the long run. This uneven pattern of convergence, in turn, suggests that the OECD countries are still far away from developing a common sustainable renewable energy target, calling for urgent international policy cooperation to encourage the divergent economies to seek out the menu of policies that ensure the worldwide success of renewable energy transformation.
Does workplace envy always have detrimental consequences in organizations? A study of public and private sector employees
(2020) Şener, İrge; Karabay, Melisa; Elçi, Meral; Erman, Halil
Purpose Based on the situational approach for envy, the purpose of this paper is to examine the effect of two-dimensional workplace envy (being envied and envying others) on the task and contextual performance of employees working in either private or public sector organizations. Design/methodology/approach This study was conducted on survey data collected from 988 private sector employees and 530 employees from the public sector employed in Istanbul. Following a quantitative empirical design, structural equation modeling was used to test the hypotheses. Findings The study results revealed that envying-others dimension has a significant negative effect on both task performance and contextual performance. In addition, the findings indicate more envious feelings of private sector employees than public sector employees. For public sector employees, male participants were found to envy others more than females. Research limitations/implications In addition to the contributions, this study has its limitations. First, although the study was carried out with a comprehensive sample, it is limited to the views of 1,518 employees in Istanbul and is a cross-sectional study. Also, employee performance is evaluated through self-reporting, which forms another limitation; it could have been more reliable for the supervisors to assess their subordinates' performance. Practical implications Apart from scholars, our findings have implications for practitioners. Feelings such as envy that comes with a sense of competition can create an environment that stimulates people, motivates them to work, can make them productive and can also cause an ultimately destructive situation. This makes it critical to manage envy in the workplace. Though there may be facilitators behind it, one crucial factor that fuels envy in the workplace is the lack of fair human resources policies and systems. Still, human resources management is undeveloped in most public organizations. With effective human resources management, there may be some roadmaps for managers to dissolve conflicts arising from envy. First, it is imperative to have systems that will separate the employee from the others, which everyone will accept, strengthening the feelings of justice among employees. Envy often occurs following a social comparison. Management can implement an incentive system that supports employee collaboration and avoid nepotism. Especially in private organizations where the competition is more among employees, managers should give more attention to understand their subordinates' feelings. The managers' attention to expressing their feelings toward their subordinates could establish an equal distance within the workplace. In this sense, language selection is critical, and managers should be mindful of linguistic triggers. Managers should not avoid giving both positive and negative feedback to their employees. Unwarranted and unsystematic reward and/or punishment systems, made with the good intentions of increasing competition, can trigger envy. Finally, managers should implement an open-door policy and open communication that will encourage all team members to be transparent to each other. Originality/value The study was based on a rationale that envy has detrimental workplace outcomes that lead to low task and contextual performance. Although there exists a recent interest for examining the relation between workplace envy and employee performance, based on being envied and envying others dimensions, these studies are limited. This study focuses on these dimensions and performance relations, and it also provides a comparative outlook for public and private sector employees in Turkey in terms of workplace envy.

Bitcoin Market Price Analysis and an Empirical Comparison With Main Currencies, Commodities, Securities and Altcoins
(Springer Science and Business Media Deutschland GmbH, 2019) Dinçergök, B.; Haşlak, Ş.; Pirgaip, B.
The purpose of this study is to analyze Bitcoin (BTC) market prices and to answer the question of whether there is a relationship between BTC and other asset prices, where other assets include currencies, commodities, securities and altcoins. In the empirical part, we evaluate the lead-lag relationships among each type of asset. Consequently, we compare BTC with major currencies and stock exchanges of the U.S., the EU, the U.K. and Japan (USD-SPX, EUR-DAX, GBP-FTSE and JPY-NIK), with currencies and stock exchanges of the U.S., the U.K., Russia, Venezuela and China where BTC is actively traded (USD-SPX, GBP-FTSE, RUB-MOEX, VEF-IBVC and YUAN-SSCE), with major commodities (GOLD and OIL) and with major altcoins (ETH, XRP and LTC) on a daily basis for the period spanning from 2010.07 to 2018.12. We employ Johansen co-integration, Granger causality, impulse response functions and forecast error variance decomposition analyses in our study. Our results show that BTC does not have a long-run relationship with any asset type, but that it has a short-run relationship with gold and especially altcoins, which are both significant and bidirectional. While BTC and altcoins are closely interrelated with each other, BTC price variation is mostly borne by its own prices in all cases. © Springer Nature Switzerland AG 2019.
The intermediary institutions which are preferred for manipulative trading: Evidence from an emerging market
(2017) Doğanay, Mete; Aktaş, Ramazan; Somuncu, Kartal
This research investigates the type of intermediary institutions chosen by the manipulators for their manipulative trading. Univariate and multivariate analyses are performed and three variables having significant effect on the manipulators’ choice of intermediary institution for their manipulative trading are found. These variables are being publicly traded, size in terms of total assets, and gross profit margin. Being publicly traded and size are positively; gross profit margin is negatively related to the manipulators’ choice of intermediary institution for their manipulative trading. Managers of the intermediary institutions and regulators should be aware of these results and regulators should scrutinize high volume transactions conducted through this type of intermediary institutions more closely.

Labor Mobility Across the Formal/Informal Divide in Turkey Evidence From Individual-Level Data
(Emerald Group Publishing Ltd, 2017) Acar, Elif Oznur; Tansel, Aysit
Purpose - This paper, the first one to use individual-level Turkish panel data, examines the labor market transitions in Turkey along the formal/informal employment divide. The purpose of this paper is to contribute to the limited body of empirical evidence available on mobility and informality in the Turkish labor market. Design/methodology/approach - Toward this end, the authors use Turkish income and Living Conditions Survey panel data for 2006, 2007, 2008 and 2009 to compute the Markov transition probabilities of individuals moving across six different labor market states: formal-salaried (FS), informal-salaried, formal self-employed, informal self-employed, unemployed and inactive. In order to examine the nature of mobility patterns in more detail, the authors then estimate six multinomial logit models individually for each transition adopting a number of individual and employment characteristics as explanatory variables. Findings - The authors find evidence that mobility patterns are fairly similar across different time spans, the probability of remaining in initial state is higher than the probability of transition into another state for all the labor market states, except for unemployment, there is only very limited mobility into the FS state. Gender, education and sector of economic activity are observed to display significant effects on mobility patterns. The results reveal several relationships between the covariates and likelihood of variant transitions. Research limitations/implications - This study provides a comprehensive and detailed diagnosis of the Turkish labor market. The market is observed to display a rather static structure throughout the period considered. The results indicate that a well recognition of underlying dynamics may help policy makers to produce various effective tools for addressing informality. Originality/value - First study to analyze labor market mobility across formal/informal sectors using newly available panel data.
Republican citizenship in Turkey: historical development, perceptions and practices
(Routledge Journals, 2011) Kardam, Filiz; Cengiz, Kurtuluş
This article, the result of qualitative research conducted in Ankara, aims to depict the republican understanding of citizenship from the behaviour patterns and daily practices of citizens and to show how it diverges from various other forms of citizenship understanding. Republican citizenship-the most dominant and hegemonic understanding of citizenship in Turkey-was constituted in the process of foundation of the Turkish Republic as a nation-state. In Turkey's historical experience, this tradition, which is based on civil responsibilities, could not develop sufficiently in terms of individual rights and democratic values. As reflected in the perceptions and practices of citizens, Turkish society is still not very close to a democratic understanding of citizenship that strongly defends human rights, legitimacy of differences, equality between people as well as embodying responsibilities for the society

Sources and Channels of International Knowledge Spillovers in Asean-5: the Role of Institutional Quality
(Wiley, 2020) Dogan, Ergun; Wong, Koi Nyen
Association of Southeast Asian Nations (ASEAN) is a dynamic and outward-looking regional economy, which has made notable progress in expanding trade and investment. This paper examines whether knowledge spillovers are prevalent among ASEAN-5, focusing on the issues of which channels and which sources are the potential drivers of total factor productivity. The findings reveal that the key spillover channels are exports and non-capital imports coming from source countries such as the Organisation for Economic Co-operation and Development (OECD) countries, the G7 countries. The institutional quality plays an instrumental role in increasing total factor productivity through foreign direct investment, especially when the spillovers originate from the OECD and the G7.

Impact of exchange rate and customs uinon on trade balance at commodity level of Turkey with EU (15)
(Juraj Dobrila ,University Pula, 2011) Yazıcı, Mehmet; Islam, M. Qamarul
This paper investigates the short-run and long-run impact of exchange rate and customs union on the trade balance at commodity-group level of Turkey with EU (15). Bounds testing approach is employed where a new strategy in the model selection phase is odopted ensuring that optimal model is selected from those models satisfying both diagnostics and cointegration. Results indicate that in the short-run exchange rate matters in determination of trade balance of 13 commodity groups out of 21 and customs union in 8 cases. Pattern of response of trade balance to exchange rate does not suggest a J-curve effect in any of cases. As for the long-run effect, neither exchange rate nor customs union has a statistically significant effect on trade balance of any of commodity groups, suggesting that those significant short-run effects don't last into long-run
Terrorism and the Stock Market: A Case Study for Turkey Using STR Models
(2014) Çorakçı, Ayşegül; Omay, Tolga
Several attempts have been made in the literature to analyze the detrimental effects of terrorist activities on the stock market. However, in neither of these studies the effects of terrorist activities on stock returns are investigated through employing nonlinear models in spite of the fact that most financial data is shown to exhibit nonlinear behaviour. This study, therefore, aims to contribute to this growing area of research by exploring the potential nonlinear effects of terrorist activities on stock returns by employing smooth transition regression (STR) models. Our results show that terrorism has a statistically significant negative effect on the stock index when the intensity of terrorist activities passes a certain threshold level. This negative effect continues for terrorist activities below this threshold level, but becomes statistically insignificant. This study by conducting the analysis within a nonlinear framework offers important insights into the investors who want to make portfolio diversification strategies against terrorism risk.
