Article Citation Count: 0Card spending dynamics in Turkey during the COVID-19 pandemic(Central Bank Republic Turkey, 2021) Kantur, Zeynep; Özcan, Gülserim; EconomicsThis paper provides an extensive analysis of card spending during the COVID-19 pandemic in Turkey by using weekly aggregated and sectoral credit and debit card spending data from March 2014 to December 2020. At an aggregated level, we show that aggregate demand decreases significantly at the early stages of COVID-19 and seems to reinstate its pre-COVID trend. However, when we include the pre-existing conditions of Turkey, the 2018 currency crisis, we observe that the recovery in demand is not that strong. To highlight the underlying reasons for structural change in aggregate demand, we estimate the model with stringency index and unemployment-related search index. The estimated model indicates that containment measures and restrictions and fear of job/income loss mainly explain the overall impact of COVID-19 on aggregate demand. We also examined sectoral data to understand aggregate demand dynamics better. Only stable and delayable sector groups have reached a trend above their pre-pandemic trajectories. However, the social and work-related sectors are far from their respective pre-pandemic trend.Article Citation Count: 0Monetary Policymaking under Climate Uncertainty(2022) Kantur, Zeynep; Özcan, Gülserim; EconomicsThe most effective policy to prevent climate change is the decarbonization of the production process. Decarbonization, which should be planned and not delayed, will cause some assets to become idle or stranded, either entirely or partially. Therefore, the transition to a low-carbon economy results in sudden and unexpected fluctuations in asset prices. These shocks will affect the relevant sector and all production sectors with a domino effect and deteriorate financial stability. To the extent that these shocks are predictable, policymakers can prepare for the repercussions of green financial transformation. However, the tools needed to pre-measure them are new and dependent on many economic variables. Therefore, policymakers need a road map to act under this uncertainty. This paper theoretically provides insights into central banks’ role/engagement under climate change ambiguity. The paper shows that the less the central bank trusts its policy model, the higher the sensitivities of inflation, output-gap, and asset price-gap to climate-related shocks. Hence, an aggressive response of monetary policy is required in the face of uncertainty.Article Citation Count: 0Türkiye'de Tüketim Modelinin Deşifre Edilmesi: Bir Euler Denkleminin İncelenmesi(2022) Kantur, Zeynep; Özcan, Gülserim; EconomicsPolitika yapıcıların ekonomik modellerinde tüketim için yapısal bir biçim varsaymaları nedeniyle tüketim dinamiklerini anlamak çok önemlidir. Bu çalışma, kredi ve banka kartı harcama verilerini kullanarak bir Euler denklemi tahmin etmekte ve Türkiye'deki tüketim dinamiklerini ayrıştırmaya çalışmaktadır. Standart Euler denkleminden farklı olarak, döviz kuru dinamiklerinin tüketim üzerindeki etkisini anlamak için bir modelleme şeması kullanılmaktadır. Bulgularımıza göre Türk Lirası değer kaybettikçe tüketim artmaktadır. Ayrıca, tüketim davranışında önemli bir alışkanlık oluşumu olduğunu gösteriyoruz. Bununla birlikte, geriye dönük harcama davranışı, gelecekteki tüketime ilişkin beklentiler tarafından domine edilmektedir.
