    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.

    Supply Response of the Wine Industry in Turkey
    (Asia Life Sciences, 2011) Sakarya, Arif Orçun; Sakarya, Arif Orcun; Temiz, Dilek; Temiz, Dilek; İşletme; Uluslararası Ticaret ve Finansman
    Regarding the high wine production potential; the main goal of the study is to discover whether there is a long run relationship between wine production, wine net export and demand and to display the possible contribution of latter variables on wine production in Turkey. Following the wine market overlook; related contribution is analyzed by using annual time series data for the years 1961-2005, the Johansen cointegration test and ordinary least squares method. The empirical findings have shown that, as the wine net export or the wine demand increases, wine production also increases in Turkey. Cointegration test has proved that there is a long run relationship between wine production and the other variables.

    Exchange Rate and Turkish Agricultural Trade Balance With Eu (15)
    (2012) Yazici, M.; Yazıcı, Mehmet; Islam, M.Q.; İktisat
    This paper investigates the short-run and long-run impact of exchange rate on the trade balance of Turkish Agriculture with EU (15) countries. The bounds testing approach to the cointegration and the error correction modeling is employed. A new strategy in the model selection phase is adopted and the optimal model is selected from the set of those models that satisfy both diagnostic tests and cointegration. Thus, unlike the previous literature utilizing this approach, it is ensured that a statistically reliable and cointegrated model is picked up for estimation. Estimation results based on the data for 1988-I to 2008-IV period indicate that in the short-run real exchange rate variable affects agriculture trade balance in trade with EU(15) and depreciation of Turkish Lira improves the trade balance. As for the long-run impact of the exchange rate, depreciation of domestic currency has a statistically significant negative effect on trade balance of agriculture.

    Ppp Hypothesis and Temporary Structural Breaks
    (Economics Bulletin, 2017) Corakci, Aysegul; Omay, Tolga; Emirmahmutoglu, Furkan; Çorakcı, Ayşegül; Tolga, Omay; Çankaya Meslek Yüksekokulu; İktisat
    In this study our aim is to explore a better testing strategy for the PPP hypothesis under a temporary structural break. For this purpose we use the exponential smooth transition (EST) function in the unit root testing framework and compare this methodology with the one that uses a Fourier function. Although the Fourier function is extensively used in the literature to test the validity of the PPP hypothesis under temporary breaks, this investigation shows that it leads to misleading results.

    Model Selection Uncertainties and Model Averaging in Autoregressive Time Series Models
    (Isoss Publ, 2012) Islam, M. Qamarul; Yazıcı, Mehmet; Yazici, Mehmet; Islam, M.Qamarul; Qamarul Islam, M.; İktisat
    Selecting the correct lag order is necessary in order to avoid model specification errors in autoregressive (AR) time series models. Here we explore the problem of lag order selection in such models. This study provides an in-depth but easy understanding of the model selection mechanism to the practitioners in various fields of applied research. Several interesting findings are reported and through these the pitfalls of the model selection procedures are exposed. In particular, we show that the whole exercise of model selection and subsequent statistical inference invariably depends upon unknown entities, namely the true values of parameters in the model. The model averaging technique is proposed as an alternative to the common practice of model selection and it is shown that, as a result, the properties of post-model-selection estimates substantially improve.

    Ülke Risk Primi Şokunun Makroekonomik Etkileri: Türkiye Örneği
    (2018) Varlık, Nimet; Gebeşoğlu, Fulya
    Ülke risk primi şokunun makroekonomik etkileri 2005:12- 2017:3 dönemi için Yapısal Vektör Otoregresyon Modeli kullanılarak incelenmiştir. Türkiye için ülke risk primi göstergesi olarak EMBI+TR kullanılan model nominal döviz kuru sepeti, tüketici fiyatları endeksi, tüketici kredileri, sanayi üretim endeksi ve cari açık bilançosunu içermektedir. Ampirik sonuçlar ülke risk priminde gözlenen yapısal şokların Türkiye’nin açık enflasyon hedeflemesi döneminde makroekonomik değişkenlerini olumsuz yönde etkilediğini göstermektedir. EMBI+ TR göstergesindeki bir standart sapmalık şok Türk Lirasında devalüasyona, fiyat seviyesinde artışa, kredi hacminde daralmaya, sanayi üretim endeksinde düşüşe ve cari açık bilançosunda artışa yol açmaktadır. Ülke risk priminin döviz kuru ve krediler üzerindeki olumsuz etkisi diğer değişkenler üzerindeki etkisine kıyasla daha fazladır. Ayrıca ülke risk primi şokları kredi daralması yaratmak suretiyle reel ekonomide küçülmeye ve cari açık bilançosunda artışa yol açmaktadır. Varyans ayrıştırmasının bulguları ile etki tepki analizinin sonuçları tutarlı olupülke risk priminde gözlenen yapısal şokların kredi üzerindeki etkilerinin diğer değişkenlere kıyasla daha fazla olduğu sonucuna varılmıştır.

    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 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.

    Private Charity and Cooperation Vs. Non-Cooperation
    (2006) Yazici, M.
    This study analyzes cooperative and non-cooperative outcomes in the context of private charity and compares them on efficiency grounds. Analysis is conducted in a model economy where there are two rich individuals and one poor and the rich care about the well-being of the poor. The results of the analysis suggest that, when making donations to the poor, the rich should get together and act cooperatively instead of behaving independently. Given the fact that there are many donors in reality and therefore it is difficult for them to get together for cooperation, this result implies a role for government to provide a mechanism for cooperation and justifies the support of the governments for charity organizations. © 2006 Asian Network for Scientific Information.
