Bitcoin Market Price Analysis and an Empirical Comparison with Main Currencies, Commodities, Securities and Altcoins
(Springer Science and Business Media Deutschland GmbH, 2019) Pirgaip, B.; Pirgaip, Burak; Dinçergök, B.; Haşlak, Ş.; Bankacılık ve Finans
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.

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.; 19320; 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.

Innovation Cluster Development Potential In the Regions of Turkey: A Geographical Perspective
(Igi Global, 2013) Sakarya, Arif Orcun; Sakarya, Arif Orçun; 19342; İşletme
The assessment of firms' innovativeness levels in a specific territory can be assumed to be an important indicator of future innovative collaboration, some of which might also be cluster setup initiatives. Assuming that geographical proximity can also provide a favorable opportunity for strengthening interfirm ties, the goal of the chapter is to discover the best innovation variables for Turkish firms in terms of being members of potential innovative cluster formations. Following an overview of the innovation parameters used in the study, the current situation of the firms in question and their problems are briefly stated. The analysis part includes a regression test to discover the variables affecting firms' innovativeness in order to tackle the problems stated. Regression results have shown that intellectual capital, technology infrastructure, and geographical concentration levels affect the innovation performance of the firms in different regions. The conclusion involves further policy improvements for empowering regional innovation capabilities.
