The simple macroeconometrics of the quantity theory and the welfare cost of inflation

The quantity theory of money hypothesizes that the price level is determined through the equilibration of money supply and demand. Predicated on this causal structure, a single-equation error correction model decomposes from a larger vector autoregressive system so as to make available bounds tests for a levels relationship that are robust to the univariate integration properties of the variables. This model is estimated using three monetary aggregates and two money demand specifications, for U.S. and U.K. annual data over the past century and quarterly post-WWII data. The classic homogeneity propositions of the quantity theory are testable, and are found to be most compatible with U.S. annual M2 using log-log money demand with structural change permitted. Nevertheless, the resulting welfare costs are similar to those yielded by the U.K. annual data, being less than one percent of GDP at interest rates experienced during the past century.

Impact of Petroleum Energy Price Volatility on Commodity Prices in Ghana

The purpose of this article is to demonstrate the relationship between petroleum energy volatility and commodity prices in Ghana, which are indexed (energy grains, meat, and cooking oil), as well as to provide an empirical specification of the impact's direction. With reference to time series literature, the paper examined energy and commodity price connection models such as augmented dickey fuller, granger causality, co-integration, vector autoregressive and the vector error correction models used in estimating the association among petroleum energy volatility and the three selected commodity variables. The paper found that, there is a long run relationship between petroleum energy volatility and commodity prices in Ghana from 2011 to 2022. A single equation error correction model suggested that, petroleum energy shocks increase prices of grains, meat and cooking oil in both the short and long run. Impulse response function and variance decomposition conducted on the variables also suggested that there is both short and long run association between the variables.

Employment to output elasticities and reforms towards flexicurity: Evidence from OECD countries

AbstractLabor market reforms in the direction of “flexicurity” have been widely endorsed as a means to increase an economy's ability to adjust to negative shocks while offering adequate social safety nets. This paper empirically examines how such reforms influence employment's responsiveness to output fluctuations (employment–output elasticity). To address this question, we employ a single equation error correction model with policy interactions on a panel of OECD countries, which also incorporates the period of the Great Recession, and distinguish between passive and active labor market policy types. Flexicurity is represented by three policy measures: unemployment benefit generosity, the flexibility of hiring and firing rules, and spending on active labor market policies. We find that the effects of any single policy change are shaped by the broader existing policy mix within which it takes place. A hypothetical flexicurity reform towards the policy mix of Denmark, a well‐known example of the flexicurity regime, is found to increase or leave unchanged countries' short‐run employment–output elasticities, depending on the initial policy mix. These results are robust to accounting for a large set of additional labor market institutions.

A new analytical approach for identifying\xa0market contagion

This study proposed a new analytical approach to identify the excessive comovement of two markets as contagion. This goal is achieved by linking latent-factor and single-equation error correction models and evaluating the breaks in the short- and long-term relationships and correlatedness in the linked model. The results demonstrated that a short-term relationship representing the market speed ratio between two markets plays a key role in contagion dynamics. When a long-term relationship or correlatedness is broken (comovement change) due to a break in the short-term relationship (market speed ratio), contagion is highly likely and should be formally declared. Bayesian posterior probabilities were calculated to determine the cause. Furthermore, this study applied this analytical Bayesian approach to empirically test the contagion effects of the U.S. stock market during the global financial crisis between 2007 and 2009 using 22 developed equity markets.

Aplikace Taylorova pravidla na měnovou politiku ČNB

This paper tests the usability of the Taylor rule under the conditions of the Czech economy using a single-equation error correction model in the period from 2000 to the second quarter of 2019 and finds key variables for the CNB's monetary policy setting. Other important monetary policy rules and their effect on the optimal monetary policy setting are also discussed. The starting point of the empirical part is a summary of the current monetary policy of the CNB and an analysis of its decision model. Since 2008, the new DSGE model g3 replaced the previous QPM model. At the end of the theoretical part, foreign experience and various approaches to the estimation of the Taylor rule are summarized. The CNB's two-week repo rate is best described by the size of the output gap in the domestic economy, the ECB's base refinancing rate, the change in the price level measured by the consumer price index and the previous value of the repo rate. The paper also analyses the relationship between the repo rate and the ECB's basic refinancing rates, confirming the historically high dependence of domestic monetary policy on the ECB's actions.

Global economic activity, crude oil price and production, stock market behaviour and the Nigeria-US exchange rate

This paper investigates the dynamic relationship among oil price, Nigeria-US exchange rate, stock market activity, Kilian's global economic activity index, and global oil production. We develop a robust, stable single-equation error correction model where the exchange rate solely bears the burden of short-run adjustments with causal influences from the rest of the variables included in the model. We find a role for asymmetry in the long run, confirming the presence of equilibrium-path adjustment asymmetry and suggesting that the positive and negative variations must be accounted for in designing the policymaking process to enforce stable exchange rate movement. By comparing the linear and nonlinear models, we find that the two models are complementary and that each is horizon-bound in its forecasting ability. • Link between oil price, Nigeria exchange rate, equity, global activity index and oil production. • A robust, stable single-equation error correction model is developed. • We find a role for asymmetry in the long-run, confirming the presence of equilibrium-path. • Find that the positive and negative variations must be adopted in model building. • We find linear and nonlinear models as complementary.

An automated approach towards sparse single-equation cointegration modelling

In this paper we propose the Single-equation Penalized Error Correction Selector (SPECS) as an automated estimation procedure for dynamic single-equation models with a large number of potentially (co)integrated variables. By extending the classical single-equation error correction model, SPECS enables the researcher to model large cointegrated datasets without necessitating any form of pre-testing for the order of integration or cointegrating rank. Under an asymptotic regime in which both the number of parameters and time series observations jointly diverge to infinity, we show that SPECS is able to consistently estimate an appropriate linear combination of the cointegrating vectors that may occur in the underlying DGP. In addition, SPECS is shown to enable the correct recovery of sparsity patterns in the parameter space and to possess the same limiting distribution as the OLS oracle procedure. A simulation study shows strong selective capabilities, as well as superior predictive performance in the context of nowcasting compared to high-dimensional models that ignore cointegration. An empirical application to nowcasting Dutch unemployment rates using Google Trends confirms the strong practical performance of our procedure.

The Dynamics of Inflation in Ethiopia: Time Series Approach

One of the prime objectives of governments is achieving stable macroeconomic condition. This objective requires that prices be kept to a reasonably stable level. High and persistent inflation introduces uncertainties into the economy and may lead to slowdown of economic growth by discouraging domestic as well as foreign investments. It may also cause balance of payments problems by eroding a country’s competitive advantage. Moreover, because it hits the poor the most it needs to be tackled. This study aims at understanding the forces behind the current inflationary process in Ethiopia. In order to achieve the stated objective a synthesis model of monetarist and cost-push inflation theories is estimated using vector autoregressive (VAR) and single equation error correction models. The estimated models enable to understand the short run and the long run inflation dynamics in Ethiopia between 1980 and 2017.The result shows that in the long run real money supply. Real GDP growth real effective exchange rate and Budget deficit have significantly affect inflation. But budget deficit and real GDP is not found the expected sign rather. The short run the change in real GDP growth and change real money supply significantly affect inflation. However the change real effective exchange rate and budget deficit are insignificant. The study suggests that adopting restrictive monetary and fiscal policy. Have essential tools to curb inflationary problem of Ethiopia.

The Contribution of Foreign Holdings of U.S. Treasury Securities to the U.S. Long-Term Interest Rate

We find empirical evidence of a possible structural break in the relationship between the foreign holdings of U.S. Treasury securities and the U.S. long-term interest rate occurring at the time when U.S. monetary policy became constrained at the zero-lower bound (ZLB). The estimated marginal effect of the foreign holdings ratio on the U.S. long-term interest rate, particularly its long-run effect, appears to have become stronger during the ZLB regime than it was before. We argue that the leading explanation of this apparent break is the nonlinearity introduced by the ZLB. Motivated by theory, we propose a flexible nonlinear specification to deal with the ZLB — a threshold single-equation error-correction model splitting the sample in two regimes, pre-ZLB and ZLB, which replaces the observed Fed Funds rate with a shadow Fed Funds rate derived from a Tobit-IV model to incorporate a broader measure of the stance of monetary policy. With this setup, we find no significant structural break in the relationship between foreign holdings and long-term rates at the ZLB. Therefore, we argue that the ZLB is a leading cause of the apparent shift in the empirical relationship. We also show that the estimated effects are not just statistically-significant, but also economically-significant. Through counterfactual analysis, we show that changes in China’s holdings of U.S. Treasury securities played an important role in explaining the 2004-2006 interest rate conundrum period and kept the long-term interest rate from going ever lower in the recent ZLB period.

Exchange Rate Pass-Through in Turkey before and after the Adoption of Inflation Targeting Regime

The impact of exchange rate change on the domestic price level which is called as exchange rate pass through has long been of interest in international economics literature. Along with the application of inflation targeting regime widely, the focus of this interest has also evolved to examine the changes in degree and speed of exchange rate pass through under inflation targeting regime. Turkey, adopted Inflation Targeting (IT) as a monetary regime between 2001 and 2006 implicitly and then explicitly, exhibits which was a genuine experience to be analyzed in this respect. From this point of view, the goal of the study is to provide a time-series analysis of exchange rate pass-through for Turkish economy based on single equation Error Correction Model estimation using the monthly data under pre-IT period 1995-2000 and post-IT period 2006-2014. Thus, we try to clarify the effectiveness of inflation targeting regime as monetary policy on the exchange rate pass-through. The findings of the study indicate that the exchange rate pass-through decreased in the post-IT period compared to pre- IT period. Accordingly, it can be argued that the implication of inflation targeting regime reduced exchange rate pass through in Turkey.

What determines the gold inflation relation in the long-run?

PurposeThe author aims to examine the long-run dynamic relation between gold price and inflation in the Indian context from 1982 to 2015. The author measures inflation using consumer price index and wholesale price index (WPI). However, this study focuses on the long-run dynamic relation between gold price–WPI inflation.Design/methodology/approachThe author uses Johansen’s cointegration technique (Johansen, 1991); single equation error correction model based on Pesaran et al. (2001) and Kanioura and Turner (2005); and the Saikkonen and Lütkepohl (2000) approach. The author also uses a time-varying regression framework in level form based on Kalman filter to examine the dynamic nature of gold–WPI relation.FindingsThe author finds no evidence of cointegration between gold and WPI. However, The author reports a significant dynamic relation between gold and inflation using a Kalman filter framework, and the comovement between these variables has in fact increased in the past decade. The results further indicate that variation in gold’s sensitivity to inflation can be explained by real effective exchange rate which supports the notion of using gold as an alternative to paper currency. Moreover, the WPI beta of gold is found to be predicted by both short- and long-term interest rate changes highlighting the monetary value of gold as a valuable asset.Practical implicationsFrom an emerging economy point of view, the results have implications for policy makers, particularly the central banks. The results of this paper caution the Reserve Bank of India against increasing its gold holdings as a reserve asset presuming that gold would preserve its purchasing power parity, at the same time providing a hedge against inflation.Originality/valueTo the best of the author’s knowledge, this is the first study to examine the gold price–inflation relation in the Indian market for such a long period of time. More importantly, the study shows that the changes in gold’s long-term sensitivity to WPI can be forecast using fundamental variables like interest rates.

Exchange Rates and Monetary Fundamentals: Evidence from Turkey

(ProQuest: ... denotes formulae omitted.)1. IntroductionExchange rates, which is simply the price of one currency in terms of another currency, are one of the key component of the macroeconomics discussions in the literature. If one want to understand why some currencies depreciate and others appreciate, the factors that cause the change in supply and demand of currencies must be investigated. These factors include various fundamentals such as real income, inflation rates, real interest rates, consumer preferences, and government trade policy. For example, Purchasing Power Parity (PPP) states that a country's currency will depreciate by an amount equal to the excess of domestic inflation over foreign inflation while Uncovered Interest Parity (UIP) suggests that the interest rate differentials change the exchange rates. Traditional Flow Approach, which is also called the balance-ofpayments view, states that exchange rate moves to keep the balance of payments in equilibrium under the assumption of no government interventions. On the other hand, nominal exchange rate fluctuations should reflect movements in a country's monetary fundamentals such as relative money, output, interest rates and prices, according to the Monetary Model of Exchange Rate Determination.One of the important debates centers on the international economics is the difficulty of predicting exchange rates by using monetary fundamentals such as money supplies, outputs, and interest rates. As stated above, some theories in the economic literature claim that the exchange rates might be determined by such fundamental variables. However, since Meese and Rogoff (1983), it has been considered that exchange rates are very difficult to predict using monetary fundamentals; in particular, a simple random walk without drift (RW), is found to produce better exchange rate forecasts than fundamental-based exchange rate models. In other words, fundamental variables do not help predict future changes in exchange ratesMeese and Rogoff's (1983) finding was a shock for economists since monetary fundamentals have long been considered key determinants of exchange rates. If their finding is true, then all exchange rate models based on the fundamentals are misleading. Therefore, large numbers of studies have attempted to refute Meese and Rogoff's findings and find positive results in favor of fundamentals-based models. One of the most well-known rebuttals to Meese and Rogoff's work is Mark's (1995) study. Mark concludes in his study that monetary fundamentals contain predictive power for exchange rate. He used the long horizon regression (or Error Correction Model (ECM)) derived from the VECM (Vector Error Correction Model). However, these two studies are not the only ones testing the predictive ability of exchange rate models. Several models such as the single equation linear models, single-equation ECM, multi-equation VECM models, time-varying parameter models, and panel models have been used in the literature in the attempt to predict exchange rates. Even though most of the authors are unable to document short-run exchange rate predictability, some of them find evidence of long horizon predictability. Nevertheless, the literature has remained pessimistic about the link between exchange rates and fundamentals.The main purpose of the study is to investigate the exchange rate predictability in Turkey by using the monetary fundamentals in the ECM. This study first examines the in-sample fit of the ECM model, and then evaluates the out-of sample forecast performance of the ECM against benchmark RW model. The fundamental value of exchange rate used in this study is obtained from Frankel-Bilson Monetary Model. The error correction term is constructed under the assumptions of zero/nonzero interest rate differentials and country specific money demand elasticities to satisfy the cointegration assumption between fundamentals and exchange rates. The in-sample analysis results present evidence that monetary fundamentals are useful to explain the long horizon changes in the logarithm of the exchange rates while the out-of sample analysis results suggest that whether the ECM or the RW explains the nature of exchange rate changes might be considered that time varying. …

Hedge Fund Styles and their Contagion from the Equity Market

AbstractWe examine the dynamic contagion process of the equity market on 10 hedge fund styles. We investigate the contagion mechanism for each style using single equation error correction and latent factor models. We find that the contagion effects of the equity market on each style index depend specifically on the fund style strategy. We demonstrate that certain fund styles are more prone to contagion from the equity market than others. Our results help illuminate the relative effectiveness of a particular strategy under certain market conditions and provide insights into the long‐standing controversy around the efficient market hypothesis.

The contagion versus interdependence controversy between hedge funds and equity markets

AbstractThis study considers the ‘contagion versus interdependence’ controversy between hedge funds and equity markets. We find that contagion effects break down the established interdependence between hedge funds and equity markets and conditional return smoothing could play a key role in the contagion process by increasing or decreasing the contagion likelihood during crisis and prosperity. It is noted that the return smoothing tends to produce a biased pattern of returns during crisis and a decreased amount of return during prosperity. These findings are obtained by linking a single equation error correction model to a factor model and carrying out quantile regression, Z‐test and Wald–Wolfowitz runs tests.

The cyclical effect of advertising

Purpose – The purpose of this paper is to provide an understanding of the effects of advertising based on economic cycles. To comprehend advertising effects in the restaurant industry from an economic cycle perspective, this study investigated both short- and long-run advertising effects under periods of economic contraction and expansion and compared those effects between the two economic periods. Design/methodology/approach – The data were collected from the COMPUSTAT database for the restaurant industry (SIC 5,812) from 1979 to 2010. To estimate the economic cycles, the 2005 year-based real gross domestic product (GDP) was used from the Bureau of Economic Analysis. Also, all variables were depreciated by the value of the US dollar in 2005. For estimation, a single equation error correction model was used to examine the short-term and long-term effects of advertising. Findings – The results of this study indicated that both the short- and long-term effects of advertising on sales growth were more obvious in contraction periods than in expansion periods. However, the short-run effects of advertising on brand equity did not significantly differ between expansion and contraction periods. Further, the long-term effects of advertising on brand equity were greater in expansion periods than in contraction periods. The findings suggest that restaurant firms should not reduce their advertising budgets during periods of economic contraction to take advantage of superior sales growth outcomes during these periods. Practical implications – The results of this study provide restaurant managers with useful practical implications. During economic contraction periods, restaurant managers should not reduce advertising budgets to take an ascendant position in terms of sales growth. Though the net positive effect at year t + 1 of contraction periods was smaller than that of expansion periods for sales growth, this is temporal and the long-run positive effect on sales growth spreads into future periods. Thus, a counter-cyclical advertising strategy could compensate for reduced sales from weak customer demands during economic contraction periods. Originality/value – There have been many empirical studies on the advertising effect in the literature. However, this study examined whether the effects of advertising differ between economic expansion and contraction periods. This specificity is helpful for industrial practitioners as well as academic researchers.

FUGA DE CAPITALES EN MÉXICO: ANÁLISIS Y PROPUESTA DE MEDICIÓN

This article will propose a methodology to measure capital flight in globalization. With the aid of social accounting analysis, a set of single equation error correction models and cointegration tests, this work estimates capital flight and compares the results, including a discussion and principle contributions. Capital flight is a short-term effect. Efforts to measure and analyze this phenomenon have faced challenges and ambiguities, especially now, with the added complexities of foreign portfolio investment and new financial derivatives. There is evidence of capital flight in some countries starting with the Great Recession of 2008, while the error correction model was applied to Mexico for the time period 1980-1998, when capital flight led to economic and financial destabilization.

Distributional Consequences of Commodity Price Shocks: Australia Over A Century

This paper studies the distributional impact of commodity price shocks over the short and the very long run. Using a GARCH model, we find that Australia experienced more volatility than many commodity exporting developing countries over the periods 1865–1940 and 1960–2008. We conduct cointegration tests to assess the commodity price shock inequality nexus. A single equation error correction model suggests that commodity price shocks increase the income share of the top 1, 0.05, and 0.01 percent in the short run. The very top end of the income distribution benefits from commodity booms disproportionately more than the rest of the society. The short run effect is mainly driven by wool and mining and not agricultural commodities. A sustained increase in the price of renewables (wool) reduces inequality whereas the same for non‐renewable resources (minerals) increases inequality. We expect that the initial distribution of land and mineral resources explains the asymmetric result.

Pension reform and capital market development in Central and Eastern European countries

The paper provides new empirical evidence for the connection between pension reform and capital market development using a sample of ten Central and Eastern European countries. Using a single equation Error Correction Model, the results confirm the existence of a strong positive short-term effect, as well as a lower magnitude positive long-term effect of the pension funds’ assets on the market capitalisation.

Structural and Cyclical Determinants of Bank Interest Rate Pass-Through in Eurozone

This paper empirically investigates the evolution and the sources of interest rate pass-through heterogeneity in the Eurozone for a sample of 11 euro area countries over the period 2003M1-2011M12. Considering two harmonized bank retail rates, we first estimate single equation error correction models (ECM) and find an important pass-through heterogeneity, both for household and firm rates, even if results suggest that heterogeneity is not a new phenomenon. On the basis of this result, we then extend our analysis by studying the role played by a large number of structural and cyclical factors on monetary policy transmission. Findings based on a panel ECM approach and a panel interaction VAR framework indicate that financial tensions and fragile economic activity following the crisis are not the only factors that explain the heterogeneous monetary transmission in the euro. The differences of financial market structures across countries, in terms of banking competition and financial market development, also explain a part of this heterogeneity. In terms of policy implications, this means that future reforms promoting a more efficient and homogeneous monetary policy transmission should not only focus on risk factors, but also try to consolidate financial integration.

International travel to and from Brazil – Overseas tourism as a luxury good and a status symbol

Using data for the period 1995Q1–2012Q4, single-equation error correction models for real tourism import demand to Brazil and real tourism export demand from Brazil are derived. According to breakpoint tests, two periods (pre-2003 and post-2003) have to be distinguished. While international travel to and from Brazil can be seen as a luxury good for the whole period, low economic growth rates at the global level and the real appreciation of the Brazilian currency “real” from 2003 onward have led to stagnating real tourism exports and decreases in long-term income and price elasticities. However, high economic growth rates in Brazil and the real appreciation from 2003 onward have led to strongly growing real tourism imports and increases in long-term income and price elasticities. In line with international travel being regarded as a status symbol in Brazil, a Veblen effect of conspicuous consumption can be confirmed for the post-2003 period.
