The structuralist theory of imported inflation: an application to South Africa

This study emphasizes the importance of identifying the origin of inflation in the present context of inflation targeting by many emerging market and transition economies. The analysis shows, based on South African data, how structural (supply) and demand inflation can be distinguished. The results indicate that South Africa's inflation experience between 1973q1 and 1998q4 is characterized by two monetary regimes. During the first regime (1973q1–1984q4) the long-run cause of inflation is demand-pull. The second regime (1987q1–1998q4) represents major changes to structural (‘imported’) and cost-push inflation. The two-year period 1985–1986 signifies structural change from the first to the second regime. Moreover, the results in the second regime remain robust when the inflation model is subjected to ‘new’ out-of-sample data until 2001q2. Evidence of structural (‘imported’) inflation in the second regime suggests that inflation should not entirely be squeezed out of the system nor should it necessarily be kept at the lowest possible level, because some inflation may be regarded as the natural by-product of the growth and development process. South Africa's inflation experience points to several lessons for existing (and potential) emerging market and transition economies with some form of inflation targeting.     

The information content of the Reserve Bank of Australia's inflation forecasts

In this article, the inflation forecasts produced by the Reserve Bank of Australia (RBA) and that generated by private forecasters, are used to assess whether the Reserve Bank possesses information about inflation that the private sector does not have. The results show that the Reserve Bank inflation forecasts embody useful predictive information about inflation, beyond that contained in private forecasts, over the recent inflation targeting period.     

The effects of learning and signaling on money demand: With an application to heterodox inflation stabilization programs

This paper develops a nonlinear vector autoregression of inflation and money growth subject to changes in regime. The regimes are fully characterized by the mean and variance of inflation and are conjectured to be the result of alternative government policies. Agents are unable to observe directly whether government actions are indeed consistent with the inflation rate targeted as part of a stabilization program. However, as part of their money demand decision, agents construct probability inferences regarding the regime. Government announcements are assumed to provide agents with additional, possibly truthful information regarding the regime.  This specification is estimated using data from the Israeli and Argentine high-inflation periods. Results indicate that the successful stabilization program implemented in Israel in July 1985 was more credible than either the earlier Israeli attempt in November 1984 or the Argentine programs. Government's signaling might simplify the agents' inference problem and increase the speed of their learning but, under certain conditions, it might also increase inflation volatility. Welfare gains from a temporary increase in real balances might be high enough to induce agents to raise their money demand in the short-term even if they are uncertain about the nature of government policy and the eventual outcome of the stabilization attempt. Statistically, the model restrictions cannot be rejected at the 1% significance level. First version received: August 1998/Final version received: January 1999     

The negative side of inflation targeting: revisiting inflation uncertainty in the EMU

ABSTRACT

This article tests the Friedman–Ball hypothesis for the European Monetary Union (EMU) countries, using a GARCH methodology. The empirical results show a positive relationship between inflation and inflation uncertainty, largely supportive of the Friedman–Ball hypothesis. Furthermore, the ECB’s price stability mandate is found to have asymmetric, if not limited, effects on inflation uncertainty since 1999, with the findings different for the so-called peripheral countries when compared to the core. For the majority of the EMU countries, shifts away from the 2% target served to increase inflation uncertainty. The credibility of the ECB since the financial crisis, in attempting to meet its 2% inflation target has seen inflation uncertainty increase for some, likely driven by inflation failing to re-anchor. Furthermore, recent periods of deflation are found to generate inflation uncertainty, with short-term price variability increasing in line with observed negative price growth for the majority of the EMU countries. The results are supportive of a U-shaped relationship between inflation and inflation uncertainty. Using spline techniques, we formally provide support for such a U-shaped relation where inflation uncertainty broadly increases below a certain threshold for each country’s inflation rate. Asymmetric effects across countries are found in the level of this threshold.     

Perceived inflation and the euro: Evidence from an Austrian survey

This paper employs an Austrian micro-dataset to analyze why inflation perceptions became disconnected from official inflation measures in the course of the euro cash changeover. We find evidence that persons who are more often confronted with prices, who expected price increases and who mentally convert euro prices into old currency prices when making price comparisons have a significantly higher perception of inflation. Furthermore, our results indicate that the latter two factors have a persistent impact. This contributes in explaining why price perceptions have not normalized for several years in some countries. The results suggest that policy measures in countries which are going to introduce the euro should address these issues in order to prevent a similar development as experienced in many euro area countries.     

试析人民币对外升值与对内贬值并存

Since 2002, RMB has shown a phenomenon which is the co-existence of the external appreciation and the domestic inflation. This new monetary phenomenon has been strengthened in the context that US dollar depreciates internationally and that domestic economy is overwhelmed with excessive liquidities. The new monetary phenomenon is the reflection of the real economy that continuing trade surplus, triggered robustly by the export-driven economy, which brings a huge amount of foreign exchange reserve and accelerates sequentially the expansion of domestic money supply. Furthermore, a refrained appreciation of RMB tends to deteriorate the domestic inflation, which is not simply a traditional concept of CPI but a broad inflation parameter including a variety of asset prices. It is sure that the new phenomenon is becoming a new challenge to the macroeconomic equilibrium as well as the decision maker of monetary policy. __________ Translated from Jingji yanjiu 经济研究 (Economic Research Journal), 2007, (9): 32–48     

A PANIC analysis on regional and sectoral inflation: the Spanish case

This article studies the stochastic properties of several inflation rates for the Spanish economy using the consumer price index (CPI) for the 17 regions and 12 groups of goods and services, and the producer price index (PPI) for 26 industrial sectors. To this end, we employ the panel analysis of nonstationarity in idiosyncratic and common components (PANIC) approach proposed by Bai and Ng (2004, 2010). This methodology enables us to decompose the observed inflation rate series into a common and an idiosyncratic component, thus allowing us to identify the exact source of nonstationarity. Our analysis provides strong evidence of the presence of a common stochastic trend driving the observed series forming the panel of CPI-based inflation rates for the regions. This, coupled with the presence of a jointly stationary idiosyncratic component, implies the existence of pairwise cointegration across the regional CPI-based inflation rates, which show a clear pattern of convergence over time. This gives an indication of increased geographical homogeneity in consumption patterns. The evidence for the panels of CPI-based inflation of groups of goods and services and PPI-based inflation of industrial sectors indicates the existence of four independent common stochastic trends. This, combined with jointly stationary idiosyncratic series, provides much weaker evidence of cross-cointegration for these two panels.     

The enlargement of the euro area: differences in relative inflation

This paper investigates the structural determinants of relative inflation (i.e. the inflation of non‐tradables vs tradables) in the context of overall inflation differentials in the EU. The analysis is based on the Bergstrand theoretical model. This framework incorporates three alternative hypotheses of relative inflation (Harrod–Balassa–Samuelson, relative factors endowment, and demand effects). Due to the lack of reliable data on capital stocks only a curtailed version of the model is tested here empirically. The various specifications of the model are estimated for the majority of EU countries, using the Pedroni panel group mean FMOLS estimator. In general, relative labour productivity and demand factors turn out to be significant and correctly signed, though evidence in favour of the latter effect seems to be less robust. In addition, differences in the determination of relative prices between the new and old EU Member States are found. They seem to be consistent with theoretical considerations and the transition phenomenon. The estimation results are very sensitive to the definition of non‐tradables. The paper also discusses policy implications for overall inflation, stemming from relative price models. It questions the usefulness of relative inflation models for the analysis of overall inflation differentials and practical policy decisions.     

The new structuralist critique of the monetarist theory of inflation: The case of the Philippines

Developing economies may be characterized by long production lags. Advanced outlays to finance working capital needs will therefore assume primary importance. With weak commodity and equity markets, the financing is usually funded by credit either from the legal banking sector or from an underground curb market. Monetary and credit contraction, espoused by monetarists as a key policy for controlling inflation, will increase the cost of financing working capital needs. This has an immediate short-run stagflationary impact coming from the supply side of the economy. The study uses a one-sector macro model to test this hypothesis on the Philippines with annual data from 1958 to 1980. The results give empirical support to the claim that the working capital cost-push, supply-side effect is strong enough, which means that austerity measures may require a heavy and costly recession before price inflation can be brought down.     

An evolutionary theory of the convergence towards low inflation rates

This paper presents an evolutionary interpretation of Barro-Gordons monetary policy game. The model describes a multi-country setup where governments and private agents are boundedly rational players. The behavioral rule of players decisions leads to the imitation of the strategy giving the highest payoff. In this evolutionary monetary policy game, we show how a low inflation state is reached from an international context dominated by inflationary policies. The analysis explains the convergence towards low inflation rates observed during the past twenty years. Moreover, the low inflation state appears to be the long-run equilibrium of the game under some conditions featuring the observed macroeconomic context.JEL Classification: E5, C72, C73 Correspondence to: A. dArtigues     

The suspension of borrowing: an implicit penalty for loan default under imperfect information

A credit seeker may be suspended from borrowing for a period of time due to a previous default. Such suspension is widely used in bank lending through credit check. Our work analyses the effects of suspension on the investment choice of borrowers under uncertainty and on the lending policy of banks facing asymmetric information. We show that suspension should be tightened at low loan rates, but loosened otherwise, to improve the repayment performance of borrowers. We also show that although credit rationing may not be completely removed due to imperfect information, the excess demand for credit or transitive waiting in the market can actually be attenuated by such efficient use of suspension. Our theoretical predictions are consistent with observed cyclical patterns of changes in lendingrates and suspension severity.     

Stock return predictability: the role of inflation and threshold dynamics

This paper argues that the nature of stock return predictability varies with the level of inflation. We contend that the nature of relations between economic variables and returns differs according to the level of inflation, due to different economic risk implications. An increase in low level inflation may signal improving economic conditions and lower expected returns, while the opposite is true with an equal rise in high level inflation. Linear estimation provides contradictory coefficient values, which we argue arises from mixing coefficient values across regimes. We test for and estimate threshold models with inflation and the term structure as the threshold variable. These models reveal a change in either the sign or magnitude of the parameter values across the regimes such that the relation between stock returns and economic variables is not constant. Measures of in-sample fit and a forecast exercise support the threshold models. They produce a higher adjusted R², lower MAE and RMSE and higher trading related measures. These results help explain the lack of consistent empirical evidence in favour of stock return predictability and should be of interest to those engaged in stock market modelling as well as trading and portfolio management.     

The information content of market-based measures for the long-term inflation expectations of professionals: evidence from a midas analysis

Long-term inflation expectations taken from the Survey of Professional Forecasters are a major source of information for monetary policy. Unfortunately, they are published only on a quarterly basis. This article investigates the daily information content of market-based measures, such as inflation-linked swaps and breakeven inflation rates, for the next survey outcome. Using a mixed data sampling approach, we find that professionals account for the daily dynamics of market-based measures when they submit their long-term inflation expectations. We propose a daily indicator of professionals’ inflation expectations that outperforms alternative indicators that ignore the high-frequency dynamics of market-based measures. To illustrate the usefulness of the new indicator, we provide new evidence on the (re-)anchoring of U.S. inflation expectations.     

Nonlinearity and stationarity of inflation rates: evidence from the euro-zone countries

Earlier studies hardly reject the hypothesis of a unit root in inflation. Few studies have examined the possibility of nonlinearity in inflation and tested nonlinear stationarity of the inflation rates. This study thus intends to fill the gap. This study utilizes the tests for nonlinearity along with the unit root tests that allow for nonlinearity in the variables to examine the stationarity of inflation rates of 12 European countries that formed the Euro Zone (EZ) later in the sample period. The results suggest that the majority of these countries’ inflation rates can be characterized by mean reversion during the floating exchange rate period. Many of them appear to be nonlinear stationary. This finding is essential in conducting applied economic studies for these countries, when constructing models whose validity relies on whether or not inflation is stationary. The results of this study also imply that shocks to inflation have a transitory effect on inflation in the euro area. Therefore, it would be less costly in exercising the policies of disinflation for the monetary authorities of the euro area than for those of the countries with nonstationary inflation.     

The dynamics of inflation: a study of a large number of countries

Over the last twenty years the statistical properties of inflation persistence has been the subject of intense investigation and debate without reaching a unanimous conclusion yet. In this article we attempt to shed further light to this debate using a battery of econometric techniques in order to provide robust evidence on the degree of inflation persistence and whether this has changed during the period in which several countries have followed inflation-targeting regimes or new monetary regimes. We consider the inflation rates of thirty developed and emerging economies using quarterly data for the period 1958 to 2007 which include alternative monetary policy regimes. The coefficient of the inflation parameter is estimated by Ordinary Least Squares (OLS), Autoregressive Moving Average (ARMA) and Autoregressive Fractionally Integrated Moving Average (ARFIMA) models. Furthermore, the grid-bootstrap Median Unbiased (MUB) estimator approach developed by Hansen (1999) is used to estimate the finite sample OLS estimates coupled with the 95% symmetric confidence interval. We also examine parameter stability of persistence coefficients by estimating a model with time-varying parameters.     

The effect of VAT rate on inflation in Latvia: evidence from CPI microdata

This article evaluates the inflation effect of recent value added tax (VAT) rate changes in Latvia by using consumer price index (CPI) microdata. Our findings suggest that the pass-through of the tax rate to consumer prices is strong in case of upward tax adjustments, especially when there are no demand restrictions, while the pass-through is weaker for tax reductions. The frequency of price changes peaks at the moment of VAT adjustment, which, however, is partially compensated by lower average size of price revisions. The level of pass-through exhibits a high degree of heterogeneity with higher pass-through for goods, especially food, and lower for services.     

Towards an information economy : The case of Singapore

Recent empirical studies have documented the emergence of information-based economies in developed countries within Europe, the U.S.A., Japan, and Australia. Casual observations suggest that the newly industrializing country of Singapore is proceeding towards a similar trend. The primary purpose of this paper is to account for the share of Singapore's national product which originates from informational activities. In particular, we define and estimate the size of Singapore's information sector within an input-output framework. Our results indicated that a sizable portion of Singapore's economy is information-based. In view of the significant penetration of informational activities in economic production, advances in communication technology and concomitant improvements in information-handling capabilities are bound to affect factor productivities and incomes with consequences for a country's pattern of employment and production structure. It is anticipated that an economics of communication becomes necessary for an awareness of communication technology as a choice variable in economic planning. We conclude our discussion with an assessment of the admissability of an information sector concept in economic analysis and the usefulness of empirical studies based on such a concept.     

The impact of China's accession to the WTO on its economy: an imperfect competitive CGE analysis

To examine the impact of trade barrier reductions on the Chinese economy following its WTO accession, a single‐country, static CGE (Computable General Equilibrium) model is constructed, which incorporates certain elements of imperfect competition in China's current economic situation. China's real GDP and total employment are expected to rise by small degrees, while the general price level may decline by a few percentage points. Total imports would rise by more than 10%, whereas total exports would increase far less. China's trade surplus is, therefore, likely to shrink substantially and its dependence upon foreign trade is likely to rise by a few percentage points. A sensitivity analysis confirms the robustness of the simulation results. A comparison with other CGE studies on China's trade liberalization also shows the plausibility of this study's predictions.

The effect of the market-based monetary policy transparency index on inflation and output variability

This paper examines empirically the effectiveness of the Federal Reserve’s policy under different levels of transparency by using a dynamic and continuous market-based index proposed by Kia (2011 Kia, A. 2011. “Developing a Market-based Monetary Policy Transparency Index: Evidence from the United States.” Economic Issues 16 (2): 53–79. [Google Scholar]) on inflation volatility and output volatility. In theory, the more transparent the monetary policy, the less volatile the money market will be with fewer disturbances and thus the more stable will be the economy. First, a bivariate VAR-BEKK-GARCH(1,1) model is estimated for inflation and output variables in the US economy in order to produce conditional variances and covariance over the period October 1982 to December 2011. Second, by incorporating conditional variances and transparency in a VAR model, impulse response functions reveal that after a positive shock in the Federal Reserve’s transparency (i.e. market participants consider the Federal Reserve’s actions to be more transparent), there is a statistically significant decrease in both inflation volatility and output volatility. Our results reveal the dynamic and crucial role that a central bank’s transparency plays in retaining economic stability and assuring the forecasts concerning inflation and economic growth made by the economic units.     

Raising an inflation target: The Japanese experience with Abenomics

This paper draws from Japan׳s recent monetary experiment to examine the effects of an increase in the inflation target during a liquidity trap. We review Japanese data and examine through a VAR model how macroeconomic variables respond to an identified inflation target shock. We apply these findings to calibrate the effect of a shock to the inflation target in a new-Keynesian DSGE model of the Japanese economy. We argue that imperfect observability of the inflation target and a separate exchange rate shock are needed to successfully account for the behavior of nominal and real variables in Japan since late 2012. Our analysis indicates that Japan has made some progress towards overcoming deflation, but further measures are needed to raise inflation to 2 percent in a stable manner.
