Besides mitigating pollution, can such investment lead to other financial benefits? In response to this research question, the objective of the current analysis is to reveal the impact of going green on the cost of production (COP) for enterprises. To achieve this aim, we conduct an empirical analysis using 10 years of data (2010–2019) from non-financial sector enterprises in BRICS (Brazil, Russia, India, China, and South Africa) economies. Due to the existence of endogeneity issues, we select the system GMM (Generalized Method of Moments) model as our estimation technique. The empirical results reveal that investment in green technologies has a non-linear negative and statistically significant relationship with COP. Initially, focusing on green investment increases the COP due to technology replacement and learning costs. However, after a certain level, such investment reduces the COP, implying an inverted U-shaped relationship between green investment and the cost of production. The conclusion of the study suggests that corporate managers should consistently invest in green technologies and adopt it as a long-term strategy. This study contributes to the literature by demonstrating the real-time role of green investment in reducing the COP.</div></div>","PeriodicalId":43998,"journal":{"name":"Central Bank Review","volume":"25 3","pages":"Article 100202"},"PeriodicalIF":2.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144242301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Does difference in monetary policy framework matter for interest rate Pass-through? Evidence from TVP-VAR with stochastic volatility","authors":"Usman Adamu Bello ,&nbsp;Auwal Isah","doi":"10.1016/j.cbrev.2025.100201","DOIUrl":"10.1016/j.cbrev.2025.100201","url":null,"abstract":"<div><div>The relative success of Inflation Targeting (IT) amidst widespread rising inflation globally is motivating the Central Bank of Nigeria (CBN) to renew its desire for an IT framework. This paper applies the Time-Varying Parameter Structural Vector Autoregression with the Stochastic Volatility model (TVP-SVAR-SVM) to examine the potential benefits and provide hindsight for the CBN within the interest rate channel. The paper draws parallels between the CBN's Monetary Targeting (MT) and South Africa's Reserve Bank (SARB) IT. The result of the SVM uncovers a disparity regarding inflation uncertainty associated with interest rate pass-through. At the same time, two distinct parallels were unveiled regarding the impulse response function (IRF) result. Although CBN was found to have experienced decelerating inflation uncertainty, the SARB's IT shows no potential benefit. Meanwhile, compelling distinctiveness from the results of the IRF is: first, relative consistency in short-term inflation forecast and the future expected inflation (8-period and 12-period) found in the SARB's IT. This was accompanied by an observed absence of distortions over the declining trajectory of inflation, which allows it to build monetary policy credibility over time, while the strong indication of achieving rapid long-run disinflation over time was also detected. Thus, confirming the relatively greater degree of expectation anchoring. In contrast, the CBN's MT showed manifestation of distortions over time, with difficulties in suppressing impending inflationary pressure, whereas the expected inflation forecast deviated from its short-term (4-period) inflation forecast. Secondly, evidence of speed in the SARB's IT during the initial impact of interest rate pass-through was twice as fast as the CBN's MT. Consequently, the total impact of the pass-through to inflation under MT was also found to be delayed by 8 periods relative to the IT. This paper concludes that the characterized evidence uncovered constitutes a relatively effective SARB's IT, and a key benefit resides in the comparatively faster interest rate pass-through in the IT. This could potentially restrain the rapidness with which nominal adjustable inflation-indexed wages under short contracts have on inflation.</div></div>","PeriodicalId":43998,"journal":{"name":"Central Bank Review","volume":"25 2","pages":"Article 100201"},"PeriodicalIF":2.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing monthly data from 2004 to 2024, the study applies a novel augmented Phillips Curve framework, integrating a Time-Varying Parameter (TVP) approach with a connectedness measure derived from the Antonakakis et al. (2020) methodology. Our aim is to investigate the interplay between consumer price inflation and sub-level pricing dynamics to understand how interconnectedness amplifies inflation persistence. This study uniquely contributes to the literature by analyzing inflation inertia alongside the influence of commodity price interconnectedness, offering a dual perspective on inflation dynamics. The findings reveal a marked increase in inflation inertia in Türkiye since 2018, driven by stronger inflation expectations and intensified price interconnectedness, particularly after 2022. The results underscore the compounded impact of synchronized pricing adjustments and sectoral linkages in perpetuating inflation persistence, which hinders the effectiveness of conventional monetary policy. Robustness checks by employing Markov Switching Regression (MSR) models, the quantile-on-quantile (QQ) regression and causality results confirm these dynamics. Policy recommendations emphasize the need for a coordinated approach, integrating monetary, fiscal, exchange rate, and income policies to reduce system-wide price interconnectedness. Central banks must adopt a clear and credible policy horizon to break inflationary expectations and mitigate inertia. By addressing these systemic challenges, policymakers can enhance the efficacy of inflation-targeting frameworks, supporting sustainable price stability in the face of entrenched inflation dynamics.</div></div>","PeriodicalId":43998,"journal":{"name":"Central Bank Review","volume":"25 2","pages":"Article 100199"},"PeriodicalIF":2.0,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143850203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low interest rates, coupled with escalating housing prices, are the key drivers of growing household debt. In this context, monetary tightening may play an opposite role to conventional monetary policy. Moreover, inordinate indebtedness likely acts as a deterrent to household consumption. Using threshold regression, this study explores the nonlinear nexus between monetary policy and household debt, as well as the nexus between household consumption and debt in Korea. The results reveal that an increase in the monetary policy rate boosts household debt in a regime with values beyond the threshold of the nominal (real) housing sales price index approximately 61.3 and 63.9 (80.7) for regressions on the regime-specific nominal and real policy rates, respectively. This implies that monetary tightening can enhance household debt due to high housing price expectations. Furthermore, an increase in household indebtedness suppresses household consumption when the household debt-to-annual GDP ratio is above the thresholds of approximately 84% and 82% for regressions on household debt growth and household debt-to-GDP ratio growth, respectively. These findings suggest that, under low interest rates, in the face of high housing prices and “excessive” household indebtedness, monetary tightening and debt expansion are unviable courses of action for resolving growing household indebtedness and declining household consumption. Therefore, when regulating the policy rate to control household debt and spending effectively, it is crucial to maintain housing prices and household indebtedness at desirable levels. In tandem with this, additional policy instruments such as macroprudential and housing-related fiscal regulations may also be needed to attain financial stability.</div></div>","PeriodicalId":43998,"journal":{"name":"Central Bank Review","volume":"25 1","pages":"Article 100190"},"PeriodicalIF":2.0,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given its significant contribution to employment, exports and national income, agricultural production-climate change relation is considerably crucial for the Turkish economy. In this paper, we investigate the impact of climate change on wheat production at the province-level with a unique, up-to-date and comprehensive dataset that is constructed by the Central Bank of the Republic of Türkiye (CBRT) under the Early Warning System Project (EWSP). In the corresponding models, climate change is initially considered in a conventional way via temperature and precipitation measures, later considered with new alternative composite climate indicators. The estimation results obtained from models with two different alternative climate measures are comparable and similar: Climate change has a statistically significant adverse impact on wheat production. Combining model estimation results with the climate scenarios, the impact of hotter springs and summers on wheat production for different time spans has been put forward. The impact is found to be increasing over time, regardless severity of the climate scenarios. We believe that our understanding regarding climate change-agricultural production relation will improve with the advancements of the data set, and this will support the development of more efficient policy recommendations.</div></div>","PeriodicalId":43998,"journal":{"name":"Central Bank Review","volume":"25 1","pages":"Article 100191"},"PeriodicalIF":2.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigation is based on a structural vector autoregression model, where sector-specific real credit card spending data (adjusted for inflation) representing an overall country, Türkiye, are used. The empirical results (in the long run) suggest that a positive shock to the monetary policy rate reduces real credit card spending in cars, health, insurance, and shopping in a statistically significant way, whereas it increases real credit card spending on airlines and travel. Monetary policy shocks contribute to the volatility of credit card spending by up to 36% for insurance, 26% for markets and shopping centers, and 22% for travel sectors, whereas this contribution is only about 3% for contractor services and about 4% for car rentals, jewelry, and casino sectors.
