Asymmetric effects of inflation shocks on inflation uncertainty

The empirically documented regularity that dis-inflationary shocks are associated with larger output changes than are positive shocks presents an interesting puzzle to macroeconomists. This paper presents, and empirically supports, a new explanation for this asymmetry. The authors show, using a TARCH model, that negative inflationary shocks result in greater inflation uncertainty than positive shocks. As Friedman [1977] argues, and a body of empirical evidence demonstrates, inflation uncertainty leads to lower output growth. Drawing on this explanation, this essay points to an avenue by which the output asymmetry of inflationary shocks can be explained.     

Inflation and inflation uncertainty in the ASEAN-5 economies

This study explores the linkage between inflation and inflation uncertainty in the ASEAN-5 countries over the period 1970:01–2007:12. Inflation uncertainty is estimated as a conditional variance in an AR(p)-EGARCH(1,1) model. Granger causality tests show that rising inflation increases inflation uncertainty and that rising inflation uncertainty increases inflation in all five countries. The ASEAN-5 have had low inflation rates relative to other emerging markets. Thus, our study shows that even in low inflation emerging markets inflation can lead to inflation uncertainty and uncertainty can lead to inflation. Given current inflationary pressures in these countries, our results warn of possible costs of not keeping inflation in check.     

Inertial linkages between wages and inflation: Evidence from Brazil

Many observers of the Brazilian economy have suggested that wage growth causes inflation. Because wage growth is linked to past price growth, an inertial component is said to exist. The relationship between wage growth and inflation in Brazil over the period 1981–89 is examined. A model of wage growth and inflation is developed. Lagged effects of inflation on wage growth and a structural break in 1986 are tested for. The estimates suggest a lagged response of wages to prices in the pre-1986 period. However, in the post-1986 period, the response of wages to lagged inflation is not statistically different from zero and the contemporaneous response is not different from one.A preliminary version of this paper was presented at Fundacão Getulio Vargas and CEBRAP in São Paulo in August 1991.

Exchange rates,price levels,and inflation targeting: Evidence from Asian countries

This study examines how the adoption of inflation-targeting influenced exchange rate pass-through and volatility in four Asian countries –Indonesia, South Korea, the Philippines, and Thailand – over the sample period of January 1990 to June 2007. We find that adopting inflation targeting helped reduce pass-through in South Korea, and Thailand, while the results are less clear for Indonesia and the Philippines. Nevertheless, the findings indicate that inflation targeting caused a decline in exchange rate volatility in all four countries. The important lesson from the experiences of these Asian countries is that the adoption of inflation targeting contributes to achieving the ultimate goal of inflation stability through reducing exchange rate pass-through or variability.     

The influence of inflation on differential price changes across European markets

This paper provides the results of an empirical study of the dispersion of consumer price inflation for each of 19 product groups across 11 European countries using monthly data covering the 1980s. The study relates the degree of inflation dispersion in a market to the mean inflation rate. Thus, we show how differential price changes across European markets are influenced by inflation. A model of asymmetric response of relative inflation variability to inflation is tested. Hypotheses are also tested regarding broad categories of traded, nontraded, and regulated products, and results are provided for individual product groups.     

Size really doesn't matter: In search of a national scale effect

I search for a “scale” effect in countries. I use a panel data set that includes 200 countries over forty years and link the population of a country to a host of economic and social phenomena. Using both graphical and statistical techniques, I search for an impact of size on the level of income, inflation, material well-being, health, education, the quality of a country's institutions, heterogeneity, and a number of different international indices and rankings. I have little success; small countries are more open to international trade than large countries, but are not systematically different otherwise. J. Japanese Int.

In search of the Phillips curve for India

The economics literature suggests that the Phillips curve is nonexistent in India. This study finds that supply shocks, namely droughts and oil crises, and the liberalization-policy shock of the early 1990s are the main reasons for the absence of the Phillips curve in India. Once I account for these shocks by reconstructing the data of inflation and the output gap in crop year instead of fiscal year, and move to the industrial sector, the Phillips curve emerges in the conventional fashion. Thus, the short-run tradeoff between inflation and industrial output is still possible in India, as it is in other developed economies.     

In search of FDI-transmitted R&D spillovers: A study based on Swedish data

In Search of FDI-Transmitted R& D Spillovers: A Study Based on Swedish Data. — This paper analyzes empirically whether inward and outward foreign direct investment (FDI) work as channels for international R&D spillovers. The authors utilize firm-level and industry-level data for Swedish manufacturing. Hardly any evidence of FDI-related R&D spillovers is found. But while the results do not provide support for the hypothesis that the activity level of MNEs’ affiliates matters for the extent of FDI-transmitted international spillovers, they suggest that utilizing foreign affiliates’ employment as a weighting scheme may be too crude a measure. The authors’ analysis shows indeed that the type of activity — R&D or assembly — carried out in the affiliates matters significantly for technology sourcing.     

Analysis of the nature of cause-and-effect relationship between inflation and wage in Russia

The nature of the cause-and-effect relationship between inflation and wages in Russia in 2003–2014 has been analyzed. The author has focused on defining the reliability of cost-push inflation theory and demand inflation theory based on Russian data using econometric methods (the Granger causality test and vector error-correction model). The stabilit y of the modeling results (for the purpose of excluding structural changes under the conditions of varying of the principles of Bank of Russia’s monetary policy during the transition to inflation targeting) is checked using the Gregory–Hansen method. In the article, the results are compared to the similar studies carried out for developed countries and countries with developing markets.     

Investment and institutional uncertainty: A comparative study of different uncertainty measures

Investment and Institutional Uncertainty: A Comparative Study of Different Uncertainty Measures. — There is ample empirical evidence of a negative relationship between aspects of institutional uncertainty and investment. Most studies, however, do not allow a comparison between different dimensions of such uncertainty because they focus on specific indicators, particular regions or different periods. The paper concludes with an evaluation of the quantitative effects of the significant uncertainty indicators on investment finding that a lack of rule of law, high corruption, and volatility in real exchange rate distortions are the most detrimental for investment.     

Euro area inflation: aggregation bias and convergence

Monetary policy of the European Monetary Union targets aggregate euro area inflation. Concerns are growing that a focus on aggregate inflation may cause national inflation rates to diverge. While different explanations for diverging aggregate euro area inflation have been brought forward, the very impact of aggregation on divergence has, however, not been studied. We find a striking difference in convergence depending on the level of aggregation. While aggregate national inflation rates are diverging, disaggregate inflation rates are converging. We find that aggregation appears to bias evidence towards non-convergence. Our results are consistent with prominent theoretical and empirical evidence on aggregation bias.     

The choice between a tariff and a quota under uncertainty

Conclusions The results concerning the choice between a tariff and a quota under the assumption of perfect competition and three kinds of uncertainty are summarized in the table. An analysis of the uncertainty, under which a government using a tariff or a quota can determine the value of imports or the quantity domestically supplied (i.e. employment), gives neither the same result for the two instruments (equivalence) nor the same result for the three situations considered. Therefore the choice between a tariff and a quota in case of uncertainty depends on the purpose, and whether the initial uncertainty concerns domestic demand, foreign or domestic supply. This conclusion corresponds to the well-known phenomenon that in case of a disturbance to an open economy the choice between a change in the rate of exchange and a change in the demand policy depends both on the goal and on the kind of disturbance.
