This paper investigates inflation dynamics in emerging markets. We apply a multi-country model (GVAR) and a time-varying Granger causality test (TVGC) to examine the drivers of inflation in Brazil, China, India, Indonesia, South Africa, and Türkiye over the period 1980Q1-2022Q4. The aim is to ascertain whether these drivers are locally or globally determined and vary over time. The GVAR model results indicate that local and global factors drive domestic inflation, collectively contributing to inflationary pressures in emerging countries. The TVGC results, on the other hand, provide strong evidence of the causality from local and global factors to domestic inflation. Local factors appear to have a stronger influence than global ones, suggesting that local dynamics play a more significant role in explaining inflation in these countries. Consequently, globalization and economic/trade integration, seen as tools to suppress inflation, can turn into factors that cause inflation in the face of a supply shock such as the one caused by the pandemic.

This study investigates the relationship between inflation dynamics and retail energy prices across Nigerian states. The paper utilizes LSDV and SYS-GMM techniques for the estimation of the static and dynamic panel models. The research disaggregates energy prices into PMS, AGO, HHK and Gas, with CPI as the dependent variable. State Revenue per capita income, representing demand-pull factor of inflation, is used to capture excess liquidity's impact on inflation. Key findings reveal that PMS, AGO, and HHK have significant and distinct effects on inflation, with PMS and AGO driving the largest increases in CPI. Gas price also contribute to inflation, but its impact is moderated by a substitution effect, where consumers shift to gas in response to rising prices of HHK and other household cooking energy sources. This substitution effect reduces the inflationary pressure from gas, making its overall contribution to CPI less pronounced. Importantly, State Revenue per capita income is positively correlated with inflation, highlighting the role of federal transfers in exacerbating demand-pull inflation. For policymakers, these findings emphasize the importance of targeted interventions to stabilize energy prices, particularly PMS, AGO and federal transfers in shaping local economic dynamics and inflationary pressures. This targeted interventions to stabilize energy prices are vital for mitigating inflationary pressures in Nigerian states, as they account for regional economic differences, ensuring more effective and equitable economic stability across the country.

We test the impact of globalization on the inflation process (global slack hypothesis) for 15 emerging economies over the period (1996Q1-2019Q4). The novelty of this article lies in testing the impact of globalization on the inflation process. We introduce the smooth transition regression (STR) model of the Phillips curve to capture the gradual impacts of globalization on inflation dynamics. The main results are as follows. (i) The asymmetries in inflation exist that are not captured by the linear Phillips curve. (ii) The domestic output gap remains a main driving force of inflation. (iii) Globalization based on the trade weighted average of the domestic output gap does not affect the inflation process compared to other variables like the trade openness, import prices, real exchange rate and international oil prices. Our results yield important implications that the central banks of the emerging economies can stabilize inflation and output gap in an effective way, exploiting the inflation-output gap relationship. When economic expansion of the trading partners increases, the process of inflation dynamics changes in two economies (Brazil, and China). [ABSTRACT FROM AUTHOR]

Central banks wish to avoid self‐fulfilling fluctuations. Interest rate rules with a unit response to real rates achieve this under the weakest possible assumptions about the behavior of households and firms. They are robust to household heterogeneity, hand‐to‐mouth consumers, non‐rational household or firm expectations, active fiscal policy, and to any form of intertemporal or nominal‐real links. They are easy to employ in practice, using inflation‐protected bonds to infer real rates. With a time‐varying short‐term inflation target, they can implement an arbitrary inflation path, including optimal policy. This provides a way to translate policy makers' desired path for inflation into one for nominal rates. U.S. Federal Reserve behavior is remarkably close to that predicted by a real rate rule, given the desired inflation path of U.S. monetary policy makers. Real rate rules work thanks to the key role played by the Fisher equation in monetary transmission. [ABSTRACT FROM AUTHOR]

Electricity prices can be an important driver of inflation. However, the transmission from wholesale electricity price to inflation depends on the type of pricing mechanism in the retail market. Using the introduction of Real-Time Pricing (RTP) in the Spanish retail electricity market, we analyze the transmission of wholesale electricity price shocks to inflation dynamics and how this transmission is affected by the introduction of RTP. The main findings are that—after RTP was rolled out—electricity price shocks display a swifter transmission to inflation while the maximum impact is around three times higher than in the previous period. This higher transmission is not only generated by a more pronounced reaction of the retail electricity price but is also caused by a greater transmission of these shocks to core inflation. These results imply that introducing RTP impacts inflation dynamics and, therefore, affects how central banks should react to this type of shock.

There has been a wide belief that real estate is a source of good investment portfolios because it has a hedge against inflation. Considering this notion, the present research examined the dynamics of the inflation-hedging capabilities of real estate investment in Nigeria's three foremost property markets, Abuja (Maitama and Central Business District), Lagos (Lekki and Victoria Island), and Port Harcourt (Rumu Ibekwe and Aba Road). To achieve this aim, this study was carried out by exploring the returns on different types of commercial properties in the chosen location and investigating the effect of inflation on such returns in order to come up with the hedging capabilities of the assets. Out of the four property prime locations in Nigeria's market, these selected study sites were purposely selected for investigation because they comprise the most desirable and preferred properties regarding location, standards, aesthetics, and value. From the data collected, a mean return, coefficient of variation, and ordinary least square regression analysis were completed. In terms of the coefficient of variation (CV), the findings reveal that the duplex in Port Harcourt exhibits the most performed investment, with a value of 0.33, compared to other locations. However, in terms of the expected return (ER), the duplex outperformed other property types in the different locations, with a return of 39.56%. Results also show that inflation has an adverse effect on the returns of the office space for the three locations considered, with the expected returns below 1%. The block of flats in Abuja has a complete defence against the three components of inflation, with a coefficient beta of 0.5633, 0.6586, and 0.8440, respectively. Thus, investors should consider inflation and other investment attributes when making decisions among arrays of investments. This will help guard against the widespread perception that real estate has a hedge against inflation. This paper adds to the existing literature on inflation hedging by investigating the effect of inflation on the real estate investment returns of commercial properties. [ABSTRACT FROM AUTHOR]

The effects of various geopolitical tensions, conflicts between countries and the global post-pandemic COVID-19 have caused an acceleration in the price level in many countries around the world. This research focuses on Mexico since its monetary policy has created intricate interactions between inflation and growth in the short and long term, maintaining recently one of the highest real interest rates in Latin America (on average 5.75% vs. the US 2.3%). This paper examines the asymmetric link between the National Consumer Price Index and the Global Economic Activity Index in Mexico during the period 1994–2023. To do this, a Nonlinear Autoregressive Distributed Delay (NARDL) model is used with monthly data, which will allow the relationship between both variables to be more adequately investigated. The main empirical finding is that upward or downward shocks to the consumer price index have caused different effects in magnitude and sign on economic growth over time. Finally, several reasonable, practical, and feasible recommendations are provided for the design of the monetary policy considering non-linear effects. [ABSTRACT FROM AUTHOR]

This paper estimates a standard Dynamic Stochastic General Equilibrium (DSGE) model that includes a wage and price Phillips curves with different expectation formation processes for Brazil and the USA. Other than the standard rational expectation process, we also use a limited rationality process, the adaptative learning model. In this context, we show that the separate inclusion of a labor market in the model helps to anchor inflation even in a situation of adaptive expectations, a positive output gap and inflation above target. The estimation results show that the adaptive learning model does a better job in fitting the data in Brazil. In addition, the estimation shows that expectations are more backward-looking and started to drift away sooner in 2021 in Brazil than in the USA. We then conduct optimal policy exercises that prescribe front-loading monetary policy tightening and easing earlier than the estimated monetary policy rule in the context of positive output gaps and inflation far above the central bank target.

Gelişmekte olan ekonomilerin önündeki en önemli problemlerden biri artan ve artışı hareketi kalıcı olan enflasyondur. Enflasyon yapışkanlığı olarak adlandırılan bu durum iktisadi ajanların enflasyon beklentilerinde bozulma meydana getirmektedir. Fiyatlama davranışının da bozulmasına sebep olan enflasyon sürekliliği para otoritesinin politika alanını daraltarak iktisadi problemlerin çözümü önünde ciddi bir engel oluşturmaktadır. Sıradan bir gelişmekte olan ekonomiye göre çok daha fazla iç ve dış şoklara maruz kalan Türkiye için bu çalışmada üç doğrusal olmayan birim kök sınaması kullanılarak enflasyon yapışkanlığı incelenmiştir. Bu birim kök sınamalarından ikisi iktisadi zaman serilerinde gözlenen tek bir yapısal değişimi dikkate alıyorken, diğeri Fourier dalga fonksiyonundan faydalanarak birden fazla yapısal değişimi modellemektedir. Ocak 2002-Mart 2022 dönemini kapsayan bu çalışmada, doğrusal olmayan birim kök sınamalarının ayrıca Rolling Windows örnekleme yöntemi ile de kullanıldığı çalışmada Türkiye’nin son 10 yılında enflasyon yapışkanlığı yaşanan dönemler tespit edilmiştir. Analiz sonuçlarına göre tek bir yapısal değişimi dikkate alan birim kök sınamalarının Türkiye için işlevsiz kaldığı vurgulanmış, yapışkanlığın gözlendiği dönemler iktisadi çerçevede yorumlanmıştır.

This paper estimates the New Keynesian Phillips Curve (NKPC) with imperfect exchange rate pass-through (alternatively, deviations from the law of one price). Our results describe the nature of inflation dynamics and business cycles under imperfect pass-through, with importance of both domestic price rigidity and import price rigidity for the US and other four open economies. The estimates of structural parameters of the import price and domestic price rigidities are not same and affect inflation-output gap elasticity and inflation-law of one price gap elasticity. The results yield implications for the stabilisation of real activity (also domestic inflation) compared to the deviations from the law of one price. [ABSTRACT FROM AUTHOR]

Employing a novel instrumental variable method, we provide three findings with the idea of introducing regime switching into the NKPC for Australia, Canada, New Zealand, the United Kingdom and the United States. First, the response of inflation to the driving force is asymmetric in expansion/contraction, and high/low inflation regimes. The switch between regimes changes the inflation dynamics, thus changing the trade-off between stabilizing inflation and the output gap. Second, price stickiness changes in regimes. The price rigidity explains the inflation-output gap and the inflation-law of one price gap relationship across regimes. Third, inflation dynamics are more forward-looking in the expansionary regime. These results yield the implications of targeting deviations from the law of one price for stabilizing inflation and business cycles. [ABSTRACT FROM AUTHOR]

The main objective of this paper is to test the ability of the new Phillips-Keynesian curve in interpreting the inflation dynamics in Algeria during the period (1990 - 2021), and to achieve the objective of the study, we relied on the descriptive and quantitative approach using the generalized moments model (GMM). The study results concluded that the effect of the expected future inflation rate, delayed inflation and the output gap is positive and significant. The impact of the change in the real effective exchange rate and the M2 monetary mass is not significant, and that past expectations of inflation and future expectations of inflation contribute in a balanced way to determining the inflation rate in Algeria.

We assess the effects of financial shocks on inflation, and to what extent financial shocks can account for the "missing disinflation" during the Great Recession. We apply a Bayesian vector autoregressive model to US data and identify financial shocks through a combination of narrative and short-run sign restrictions. Our main finding is that contractionary financial shocks temporarily increase inflation. This result withstands a large battery of robustness checks. Negative financial shocks help therefore to explain why inflation did not drop more sharply in the aftermath of the financial crisis. Our analysis suggests that higher borrowing costs after negative financial shocks can account for the modest decrease in inflation after the financial crisis. A policy implication is that financial shocks act as supply-type shocks, moving output and inflation in opposite directions, thereby worsening the trade-off for a central bank with a dual mandate.

This paper provides new evidence on the role of expectations for the change in unemployment dynamics over time. We show that unanticipated changes in expectations display large and persistent effects on the unemployment rate in the 2007–09 downturn, contributing to maintain unemployment high well after the most recent recession. We also find that the changes in the autocorrelation of the unemployment rate and its correlation with inflation generated by unanticipated changes in unemployment expectations help to rationalize the pattern observed in the data in the post‐1990 recessions.

Standard theory of consumer behavior stands on the maxim of utility maximization. Optimizing behavior of consumer is achieved by maximization of utility subject to budget constraint. An increase in inflation that is not accompanied by proportionate increase in income can leave a consumer worse off. Therefore, it is imperative for consumers to have right assessment about inflation which in turn requires appropriate modelling of inflationary behavior. This study assesses efficacies of different versions of new Keynesian Phillips curve for capturing dynamics of CPI inflation. Estimation of different formulations of this curve is achieved by employing generalized method of moments. This choice of estimation technique is made to handle potential problem of endogeneity. Countries with different resource and market structures are included to evaluate and compare fitness of different formulations for different economies. Economies of Pakistan and Turkey represent developing economies, economy of South-Korea is incorporated for emerging market economy and economies of Canada, UK and US are included for developed economies. The results of this study reveal that internal as well as external factors are crucial for explaining inflationary behavior of developing economies. Whereas, dynamics of domestic inflation for advanced economies are mostly explained by internal factors.

The policy debate in Turkey over the impact of interest rate on inflation concerns the question of what policymakers should do when faced with volatile and high inflation. Motivated by this discussion, we provide an empirical analysis by connecting the cost channel to the Phillips relation. Our findings prove the existence of the cost channel. However, other determinants of inflation —labor share of income, prices of imported inputs, and consumption goods —dominate the cost channel in Turkey. [ABSTRACT FROM AUTHOR]

Recent research in macroeconomics has sought to develop a tractable form of heterogeneity in attempting to model sluggish responses in the price level. In addition, economists have struggled to explain why the demand for safe assets has increased as evidenced by the decline in real interest rates and even nominal interest rates in the last three decades [King, M (2017). Uncertainty and large swings in activity. In National Bureau of Economic Research Martin Feldstein Lecture, Cambridge, MA: NBER Summer Institute; King, M and D Low (2014). Measuring the 'World' Interest Rate. National Bureau of Economic Research Working Paper 19887, Cambridge, MA]. We build a simple two-period lived overlapping generations model that displays both heterogeneity of expectations and robustness. Our goal is to derive the economic impacts associated with greater uncertainty; more specifically, to answer the question can these two versions of uncertainty account for an increase in the demand for money and the low return on safe assets? Since analysis of even such a simple model requires a lot of technical work, we put most of this technical work into a rather lengthy technical Appendix for the benefit of readers who wish to follow such details. The main text in the paper will just focus on the basic economics. [ABSTRACT FROM AUTHOR]

Price inflation in the U.S. has been slow to pick up in the last two decades. We show that this missing inflation can be traced to a growing disconnect between unemployment and core goods inflation. We exploit rich industry‐level data to show that weakening pass‐through from wages to prices in the goods‐producing sector is an important source of the slow inflation pickup. We develop a theory where markups and pass‐through depend on firms' market shares and show that increased import competition and rising market concentration reduce pass‐through from wages to prices. We find strong empirical support for these predictions. [ABSTRACT FROM AUTHOR]

This paper aims to analyse the relationship between the euro/dollar exchange rate and oil prices and examine what effect this relationship had on the transmission of oil price fluctuations to headline inflation in the euro area since the currency's creation. We estimate an augmented Phillips curve including changes in oil price, through which we study the role of the exchange rate in oil price pass-through by using different specifications. The main findings reveal a positive relationship between the euro/dollar exchange rate and oil prices, such that an increase in the price of oil is followed by an appreciation in the euro. We also find that the transmission of oil price fluctuations to headline inflation in the euro area has been partially dampened by this appreciation in the euro/dollar exchange rate. These results do not hold for other economies with internationally relevant currencies, such as Japan and the United Kingdom. These findings have important implications for the implementation of monetary policy in the euro area in the face of oil price shocks. [ABSTRACT FROM AUTHOR]

Using a new survey of firm managers, we investigate whether inflation expectations in New Zealand are anchored or not. In spite of 25 years of inflation targeting by the Reserve Bank of New Zealand, firm managers display little anchoring of such expectations. We document this finding along a number of dimensions. Managers are unaware of the identities of central bankers or of central banks’ objectives, and they are generally poorly informed about recent inflation dynamics. Their forecasts of future inflation reflect high levels of uncertainty and are extremely dispersed, and they are volatile along both short-run and long-run horizons. Similar results can be found for the United States using currently available surveys.

This paper studies the implications of globalization for the dynamics of macroeconomic variables over the business cycle for a small open trade-dependent economy, such as South Korea.We study the impact of globalization through the lens of a structural model. Globalization is modeled as a time-varying degree of openness in the economy. We estimate the model allowing for non-fully rational expectations, learning by economic agents, and incomplete international financial markets.The empirical results show that globalization led to important changes in the macroeconomic environment. Domestic variables have become much more sensitive toward global measures over the 1991-2012 sample. In particular, domestic output and inflation are significantly affected by global output. Fluctuations in Korean output, inflation, and interest rates, which were driven for the most part by domestic shocks in the early 1990s, are, by the end of the sample, due in large part (roughly 70%) to global shocks (and shocks that are open-economy in nature).

We study inflation dynamics in emerging, small open economies of Central and Eastern Europe (CEE) and find new empirical evidence of the existence of the New Keynesian Phillips Curve (NKPC). Acknowledging specification uncertainty, a comprehensive set of alternative proxies for the NKPC's components is assessed. Our results indicate the superiority of labor market measures for economic slack, support the use of survey inflation expectations and confirm the NKPC's open economy version. Further, we investigate the stability of the NKPC over time, performing Bayesian inference in a time-varying parameter stochastic volatility version of the model. The results do not suggest the NKPC to have flattened in CEE challenging recent evidence in advanced economies. Inflationary dynamics have not decoupled from the state of the domestic economy. Therefore, a balanced approach to monetary policy which neither neglects the domestic nor external drivers of inflation and focuses on anchoring inflation expectations is well justified.

Summary: We build a time‐varying parameter model that jointly explains the dynamics of euro area inflation and inflation expectations. Our goal is to explain the weak inflation during the post‐financial crisis economic recovery of 2013–2019. We find that the inclusion of survey data leads to a more muted decline of trend inflation in recent years and more economic slack. Moreover, the impact of economic slack and import prices on inflation has recently strengthened, and survey respondents updated their beliefs more actively over the financial crisis period. Our model compares well against restricted specifications in terms of forecast performance and marginal likelihood. [ABSTRACT FROM AUTHOR]

The technological progress is transforming economy, trade and also their determinants and dynamics. Technological developments have serious effects on payment services, especially in the last 20 years. The world has been in a low inflation period compared with the previous periods. In this context, this study investigates the relationship between electronic payments and inflation dynamics in Turkey. A single equation model with the electronic payments variables is applied with quarterly data between 2005:3 - 2016:3. In the equation, the total number and total volume of transactions in the electronic fund transfer system are used as proxies for the real economy and monetary policy actions. The estimation results show that both the volume and number of transactions have effects on inflation dynamics. [ABSTRACT FROM AUTHOR]

The New Keynesian Phillips Curve (NKPC), a fast-evolving model developed, describes the relationship between inflation and unemployment. The model wields several advantages including its development from micro-foundations, the inclusion of future expectations in modeling inflation thus makes monetary policy systematic and its ability to replicate the inflation dynamics found in data. Despite its interesting attributes, result obtained from countries such as the USA, EU countries and South Africa amongst others show that the model has significant setbacks including its somewhat inability to replicate the actual relationship between inflation and economic output, the overstating role of expectations in price setting, and the relative importance of lagged inflation in the model. To test its performance for Nigeria, which is nonexistent, this study is developed. It employs the Hybrid- NKPC for Nigeria using a quarterly dataset from 2000Q1 -2018Q4. The time frame is chosen due to the availability of data. The NKPC model relates current inflation to future expected inflation and the output gap. The H-NKPC is an extension of the basic NKPC model with the inclusion of the lagged inflation in the model, also developed from micro-foundations. In the estimation of H-NKPC, two sets of results are obtained, first using the detrended output and second using marginal cost proxied by share of labor compensation in income. Results are obtained using Generalized Methods of Moments (GMM). In the first case, using detrended output results strongly support the importance of forward-looking factors, the need for the lagged inflation but the output gap is not statistically significant as a driver of inflation. In the second case using marginal costs, similar results are obtained. That is, both future expected and lagged inflation are statistically significant, but with the real variable that is, the marginal cost is statistically insignificant. Thus, the result lends support to H-NKPC which implies that lagged inflation is a significant part of inflation determination in Nigeria. These results suggest the dominant price-setting behavior is forward-looking. Furthermore, neither real marginal costs nor output gap is found statistically significant. As empirical evidence suggests, changes in real economic activities are the relevant determinant of inflation, thus different perspectives on the output gap such as the use of lagged marginal costs or growth rate of marginal costs may suffice.

This study contributes to the literature on inflation dynamics by examining whether internal or external factors drive inflationary pressure in Nigeria. Using the annual time series data from 1981 to 2017 and applying Johansen cointegration analysis, the vector error correction mechanism and the impulse response function, the study reveals some compelling evidence to suggest that external forces are responsible for inflationary pressure in Nigeria. The results, amongst others, reveal that: external drivers – exchange rate, imported inflation and openness – induce a positive and direct relation to inflation. This is because a percentage change in these variables results in an increase in inflation of 0.49%, 0.47% and 4.28%, respectively, on average, ceteris paribus; the internal drivers – government expenditures, net food exports and lending interest rate – dampen inflation by 0.48%, 1.70% and 0.02%, respectively, on average, ceteris paribus; there is evidence of cointegration indicating that 57.48% of short-run errors will be corrected in the long run; imported inflation contributes to a deviation of about 33% deviation in the first five periods and accounts for cumulative average of over 100% deviation in inflation. Policy implications are discussed.

The empirical literature provides mixed results on the relationship between inflation and unemployment; therefore, there is no consensus on validity and stability of the Phillips Curve. It also seems to be closely related with country-specific factors and the examination time periods. Considering the importance of this trade-off for policy-makers, this study aims to examine validity and stability of expectations-augmented Phillips Curve across 41 countries focusing on three different time periods between 1980 and 2016. The study documents several findings both in country-specific and in panel estimation analysis. First, we find that forward-looking characteristic of inflation picks up weight after 1990’s which indicates that inflation became more sensitive to the expected prices. Second, we observe that inflation in developed markets is more forward-looking comparing to emerging and frontier markets. This indicates that developed markets dear forward-looking price expectations more than other markets. Third, we find that that both forward- and backward-looking Phillips Curve fails to work in Brazil, Greece, Indonesia, Mexico, South Africa, Romania, and Turkey. We address it to their long history of high and volatile inflation.

This paper examines a comparative view of the inflation dynamics in three African countries. The study used monthly data from January 2007 to April 2018. To achieve the objectives, the study was deployed varieties of econometric methods. The exploratory analysis reveals that inflation of the sampled countries exhibits similar trends over the long run. The Johansson Co-integration test result evince that inflation, oil price and exchange rate of Ethiopia and South Africa had a long run relationship. Exchange rates had significant positive effects on inflation dynamics of both countries while world oil price contributes positively in Ethiopia but negatively in South Africa. In the short run, inflation in Kenya was found to be a sign of Ethiopia’s inflation. Likewise, in South African inflation was an indicator of the inflation in Kenya whereas inflation in Kenya and Ethiopia could not predict inflation would occur in South Africa. Furthermore, the outcome of the impulse response function demonstrates that exchange rates and oil price shocks affected inflation dynamics of the sampled countries at different stages both directly and indirectly. In the short run, shocks to inflation have an interaction effect across the selected countries. The findings also report that world oil prices are not equally contributes for inflation dynamics in the sampled countries.

This study investigates under which circumstances trade has impact on inflation dynamics by examining the independent effects of trade intensity, intra‐industry trade and trade on value added. Trade in goods is decomposed into consumption (final) goods and intermediate inputs to deepen the assessment of the role of the globalisation of production activities on inflation dynamics. Open‐economy new Keynesian Phillips curve (NKPC) analyses suggest that inflation is sensitive to domestic factors and that the relevance of external factors changes with respect to the nature of trade, country groups and time. Vertical intra‐industry trade in intermediate inputs and value‐added trade play important role, whereas final goods trade has no statistically significant effect on inflation dynamics.

Recent studies have argued that the New Keynesian Phillips curve (Calvo pricing model) is empirically valid, provided that real marginal cost rather than detrended output is used as the variable driving inflation. One interpretation of this result is that real marginal cost is not closely related to the output gap, and so models for monetary policy need to include labor- market rigidities. An alternative interpretation is that marginal cost and the output gap are closely related, but that the latter needs to be measured in a manner consistent with dynamic general equilibrium models. To date, there has been little econometric investigation of this alternative interpretation. This paper provides estimates of the New Keynesian Phillips curve for the U.S., the U.K., and Australia using theory-consistent estimates of the output gap. Using this theory to measure the output gap leads to a considerable improvement in the empirical performance of output-gap- based Phillips curves. [ABSTRACT FROM AUTHOR]
