Özet:

Consumer loans play a driving role in economic growth by creating an important momentum in the economy. In this context, the aim of the study is to examine the relationship between economic growth and consumer lending between 2006Q1-2020Q2 in Türkiye. In the study, the rate of change in the chained gross domestic product with the seasonal and calendar adjusted expenditures method as the growth variable, the volume and amount variables as the lending variable, and Biggs et al. (2009) credit impulse (the ratio of changes in credit flows to economic growth) variable, which is introduced to the literature, is used. In addition to the credit impulse in the literature, two more credit impulse models are installed, and these models are also included in the analysis. ADF, Phillips-Perron, KPSS and Fourier KPSS unit root tests are applied to the variables in the analysis. The causality relationship between the variables is examined by Fourier Granger causality and Toda Yamamoto causality tests. According to the results of the Fourier Granger causality test, consumer credit volume and consumer credit impulse, calculated with annual real volume and GDP data, is the reason for economic growth. According to the results of the Toda Yamamoto causality test, consumer lending amount and consumer credit impulse, calculated with annual real volume and GDP data, is the reason for economic growth.
