  The relationship between housing prices and inflation rate in Turkey: Evidence from panel Konya causality test

  Korkmaz, Özge

  Purpose: Human beings need shelter as the beginning of their existence. Same holds true for people who live in Turkey as it is a cultural and traditional reason to be the host and endeavor to buy a home even if one has to pay the debt for years. Another factor that is important for individuals and even for countries is the inflation rate. In this context, the purpose of this study is to investigate whether the 26 regions of Turkey are affected by the inflationary pressure, specifically in the housing price index (HPI). Design/methodology/approach: For this purpose, data from 2010:01 to 2019:01 and the consumer price index (CPI), as well as HPI have been used. The causal relationship between the variables is analyzed by Konya Causality (2006) test. Findings: The key results suggest that HPI causes inflationary pressures in some regions. Research limitations/implications: The study has some limitations in terms of data set and scope. These are as follows: although there are many variables affecting housing prices, this study aims to investigate the causal link between inflation and housing prices. In addition, only the CPI and HPI variables were provided on a monthly basis in the 2010-2019 period for 26 regions due to the aim of making regional propositions in the investigation of this relationship. For these reasons, different macroeconomic variables could not be studied. Originality/value: This study makes the following contribution to the literature. While the majority of existing literature investigates the relationship between housing prices and inflation from an empirical perspective for country, very few studies have been for the sub-regions and also these studies have focused on only some sub-regions. In other words, in the literature review, a study has observed that Turkey has to examine the relationship between the housing price and inflation variables for all sub-regions in particular. To overcome this deficiency in the literature, this study aims to investigate the relationship between housing price and inflation for 26 regions.

  The relationship between renewable energy consumption and economic growth The case of Bulgaria

  Can, Hamit; Korkmaz, Ozge

  Purpose The purpose of this study is to investigate the relationship between renewable energy and economic growth of Bulgaria. Design/methodology/approach This study analyzes the relationship between renewable energy and economic growth of Bulgaria for the period 1990-2016, based on annual data, by using the Toda-Yamamoto analysis and Autogressive Distrubuted Lag (ARDL) bound test. This period is characterized by the democratization of the Balkans and several crisis cycles in Bulgaria. Renewable energy consumption (REC, percentage of total final energy consumption), renewable electricity output (REO, percentage of total electricity output) and economic growth (GDP constant 2010 US$) were used. The levels or differences of the variables that are stationary were investigated using the augmented Dickey-Fuller (ADF), Philips-Perron (PP) and Kwiatkowski-Philips-Schmidt-Shin (KPSS) unit root tests. Findings Three different results were obtained from this study. One showed that renewable energy consumption and renewable electricity output are the causes of economic growth. Another result of this study is that economic growth and renewable electricity output are the causes of renewable energy consumption. The last result is that economic growth and renewable energy consumption are not causes of renewable electricity output. There was no long-term relationship between variables. Originality/value This study is an original work for Bulgaria, showing the results of the relationship between renewable energy and economic growth. In line with the results of this study, renewable energy projects related to Bulgaria can be predicted.

  The Relationship Between Credit Utilization Rate and Inflation Rate: A Case Study of Turkey

  Korkmaz, Ozge

  The reforms to be made in relation to the determination of the relationship between inflation rates and loans in a country are very effective in the success of the anti-inflation programs. Within this context, the aim of this study to investigate the impact of utilization rates of consumer loans as well as commercial and corporate credit cards on the volatility of consumer price index (CPI) and producer price index (PPI) in Turkey for the 2005:12-2018:1 period. In this study, the interaction between variables was investigated by using symmetric and asymmetric conditional volatility models. As a result of the study, it was found that the rates of credit use raised the volatility of inflation rates while the use of installment commercial loans and corporate credit cards reduced their volatility.

  Detecting housing price bubbles using panel unit roots tests

  Korkmaz, Özge

  The current developments in the global economy indicate that fluctuations in housing price have important effect on macroeconomic stability. Housing price is one of the indicators of household prosperity. Therefore, excessive volatility in housing market may influence macroeconomic prosperity. Especially it has recently seen higher increases in housing price in Turkey than in previous years. The aim of the study is to investigate regional house price bubbles in Turkish housing market using different panel unit root tests, which are CADF, SURADF, PANKPSS, Fourier KSS, sequential ADF and generalized sequential ADF unit root tests and KPSS stationarity test with sharp and smooth breaks. Therefore, the advantages and performances of so-called unit root tests were compared. The results of the analysis show that the presence of the bubbles in some regions was evidenced by CADF and SURADF unit root tests, while any evidence regarding the presence of bubble was not found by PANKPSS, FKSS unit root tests and KPSS stationarity test with sharp and smooth breaks. This study contributes to the existing literature in comparing of new methods used in detecting of the bubbles in housing prices.

  Selected Topics in Applied Econometrics

  Akay, Ebru Çağlayan; Korkmaz, Özge

  This book aims to bring together studies using different data types (panel data, cross-sectional data and time series data) and different methods (for example, panel regression, nonlinear time series, chaos approach, deep learning, machine learning techniques among others) and to create a source for those interested in these topics and methods by addressing some selected applied econometrics topics which have been developed in recent years. It creates a common meeting ground for scientists who give econometrics education in Turkey to study, and contribute to the delivery of the authors' knowledge to the people who take interest. This book can also be useful for «Applied Economics and Econometrics» courses in postgraduate education as a material source.

For this purpose, a panel regression analysis was made on a sample consisting of 12 banks and 5 insurances operated in Stock Exchange Istanbul, using quarterly data for 2008-2015 period. The price to book ratio and Tobin’s Q is used as a dependent variable in the study. Liquidity, return of equity, leverage ratio, size, asset growth and intangible asset ratios are used as independent variables. According to the results of the regression analysis, it is determined that the leverage ratio in insurance companies affects the price to book ratio positively and the return on equity negatively.
