To this end, we estimate network connectedness using a Lasso VAR model and time-varying analyses using a rolling linear VAR model for the pre-crisis and post-crisis periods. Our empirical results provide evidence of a high connectedness of house prices, with a greater degree of connectedness witnessed during the post-crisis period across regions in Turkiye. The results further divulge that Ankara (region TR51) is a major transmitter of connectedness ¨ during the pre-crisis period, while Istanbul (region TR10) is a major transmitter of connectedness during the post-crisis period. By and large, our results show that the degree of connectedness is associated with the period of financial and economic destabilization, characterized by a significant depreciation of the local currency, rising inflation rates, and an increasing cost of borrowing accompanied by rising loan restructurings and defaults. Furthermore, the empirical results indicate substantial evidence of a positive impact of consumer sentiment on the degree of connectedness during the post-crisis period. These empirical results are validated by the results of the time-varying Granger causality testseninfo:eu-repo/semantics/openAccessHouse prices; Network analysis; Connectedness; Granger causality; Macroeconomic crisis; TurkiyeArticleN/AWOS:001169547100001N/A2-s2.0-8516961787110.1016/j.bir.2023.08.006
