Understanding changes in exchange rate pass-through

Recent research suggests that there has been a decline in the extent to which firms “pass-through” changes in exchange rates to prices. This paper provides further evidence in support of this claim. Additionally, it proposes an explanation for this phenomenon. The paper then presents empirical evidence of a structural break during the 1990s in the relationship between the real exchange rate and CPI inflation for a set of fourteen OECD countries. It is suggested that the recent reduction in the real exchange rate pass-through can in part be attributed to the low inflationary environment of the 1990s.     

The Quantity and Quality of Schooling and U.S. Labor Productivity Growth (1870–2000)

This paper accounts for the contribution of the quantity and quality of schooling to worker productivity growth in the United States from 1870 to 2000. Schooling investments rose dramatically over the period before leveling off around 1970. Schooling likely caused 30 to 40 percent of the fivefold rise in worker productivity from 1870 to 1970 and produced a “wave pattern” in productivity growth (previously attributed solely to the timing and diffusion of important technological innovations). The results suggest that about 1 percent of the century-long 1.6-percent growth rate in worker productivity is sustainable. Journal of Economic Literature Classification Numbers: O47, J24.     

Do inflation targets anchor inflation expectations?

We suggest a simple test of whether an inflation target anchors private-sector inflation expectations. The test is easy to compute and it is robust to various sources of misspecification. The test may be a useful alternative to dispersion measures commonly studied in research on inflation targeting. Using data for 22 inflation targeting countries, we find for many countries that the forecasters scatter their inflation forecasts away from the inflation target. We account for the endogeneity of inflation targets, we study the variability of our finding across countries and across time, and we study to which extent our results depend on the level and variability of inflation targets.     

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.     

Non-linearity in the inflation–growth relationship in developing economies: Evidence from a semiparametric panel model

Using data on developing economies, we estimate a flexible semiparametric panel data model that incorporates potentially nonlinear effects of inflation on economic growth. We find that inflation is associated with significantly lower growth only after it reaches about 12 percent, which is notably lower than the comparable estimate obtained from a threshold model. Our results also suggest that models with restrictive functional form assumptions tend to underestimate marginal effects of inflation on economic growth. We also document significant variation in the effect of inflation on growth across countries and over time.     

The relationship between the inflation rate and its variability: the issues reconsidered

This paper empirically reexamines the hypothesis of a positive relationship between the inflation rate and its variability. The sample consists of 66 countries for the 1955–85 sample period. Using pooled cross-section time series data, empirical tests are performed for nine different country-groupings ranging from the G–7 developed countries to a group of 10 developing Asian countries. Several important conclusions can be derived. First, irrespective of the variability measure employed, the results indicate the presence of a significant positive relationship between the inflation rate and its variability. This provides strong support to Okun's hypothesis. Second, this relationship is stronger during the flexible rather than the fixed exchange rate period. Third, there appears to be an optimum zone of inflation rate within which the predictability of inflation is at its highest and hence uncertainty cost is at its lowest. For the 1955–85 sample period, this optimum zone of average inflation rate lies in the range of 5 to 7 percent.

The optimal neglect of inflation: An alternative interpretation of UK monetary policy during the “Great Moderation”

This paper argues that UK monetary policymakers did not respond to the inflation rate during most of the “Great Moderation” that ran from the early 1990s to the mid-2000s. We derive a generalisation of the New Keynesian Phillips curve in which inflation is a non-linear function of the output gap and show that the optimal response of the policy rule to inflation depends on the slope of the Phillips curve; if this is flat, manipulation of aggregate demand through monetary policy does not affect inflation and so policymakers cannot affect inflation. We estimate the monetary policy rules implied by a variety of alternative Phillips curves; our preferred model is based on a Phillips curve that is flat when output is close to equilibrium. We find that policy rates do not respond to inflation when the output gap is small, a situation that characterised most of the “Great Moderation” period.     

Relative price variability and inflation: The Italian evidence

Using Italian data from 1954 to 1983, it is found that relative price variability and inflation are positively correlated only during the 1970s and the early 1980s, when their relationship appears to be largely induced by movements in the oil price, rather than by aggregate demand shocks. This result is consistent with the findings of Fischer, 1981, Fischer, 1982 for the U.S. and Germany (although, in contrast to the evidence for these two countries, no relationship can be detected between unexpected inflation and relative price variability). Furthermore, the comparison between the three countries provides substantial support for the hypothesis — tentatively advanced by Fischer (1982) — that the correlation between relative price variability and inflation is enhanced by monetary accommodation of real shocks. There is also evidence that in Italy both variables have been considerably affected by exchange rate movements.     

Universities and intellectual property rights in Southern European countries

This paper analyses and discusses the patenting activity of Public Research Organizations (PROs) in Southern European countries. Despite the importance of the topic, studies about the European experience are rare. By using an original database of “American” (USPTO) and “European” (EPO) patents held by PROs in Portugal, Spain, France, Italy and Greece, we observe that the number of university patents in these countries has not increased dramatically during the last years, despite a growing interest at both European and national level during the same period. However, differences do exist among countries in terms of number of granted patents and regulative frameworks. With regard to PROs patenting strategies, we argue that PROs should be progressively able to adopt a “balanced” approach, in order to achieve co-existence between the traditional mechanisms of the so-called “open research system” and the more recent concerns about intellectual property protection, technology transfer and regional development.     

Increased price flexibility and output stability

Simulation results of previous authors show an ambiguous effect of increased price flexibility on output stability in models incorporating a Mundell inflation effect on aggregate demand. This paper interprets their results in an analytically tractable model with imperfect, goods-market competition. To be destabilizing, increased flexibility must increase the “hump” of the price level's response to demand shocks. Output variability is always reduced by increasing the size of the flex-price sector and sometimes reduced by shortening contract lengths in the fix-price sector.     

Ireland and Switzerland: The jagged edges of the Great Inflation

Ireland and Switzerland both had rising inflation during the early 1970s, but their experiences diverged thereafter, so that they form a rare example of two countries whose inflation rates are poorly correlated with one another over the Great Inflation period. This paper proposes that the monetary policy neglect hypothesis can account for both countries’ experiences. Extensive archival evidence is considered for each country regarding the doctrines that guided 1970s policymaking. This evidence establishes that Switzerland's better record is accounted for by the competition between monetary and nonmonetary views of inflation being resolved earlier and more decisively in favor of the monetary view. In Ireland, by contrast, nonmonetary views of inflation dominated policymaking throughout the 1970s.     

Reexamining the relationship between inflation and growth: Do institutions matter in developing countries?

Using a large panel of countries during the period 1950–2009, we estimate the inflation thresholds above which its association with economic growth is expected to be negative, taking into account differences in institutions across countries. First, in line with previous literature, we find that the estimated threshold is substantially higher for developing countries compared to that of developed countries. However, we further show that the inflation threshold in developing economies falls when we consider reduced groups that exceed certain levels of institutional quality. We also find that the cost of inflation increases with the quality of institutions.     

The future of fiscal federalism

For at least three decades after World War II, there was little interest in fiscal decentralization. Because of the large growth in public spending that took place during that period, a growth that was mainly focused at the central government level, this was a period characterized by fiscal centralization in most countries. Starting in the late 1970s, a reaction against large governments started. This reaction followed two distinct tracks: privatization and fiscal decentralization. The paper argues that these two tracks were almost two sides of the same coin and were largely mutually exclusive. They reflected similar concerns and objectives. In more recent decades, globalization has been creating global public goods or public “bads” and international activities that would require public attention or the action of a “world government”. Because no such government exists, its role is progressively being delegated to proxies, in the form of international organizations, agreements, treaties, accords and other forms of international understandings. The paper concludes that this development is likely to weaken over time the role of central governments. It also speculates that it may strengthen the importance of municipalities.     

Inflation and real sectoral output shares: Dynamic panel model evidence from seven OECD countries

Models of the cost of inflation often conclude that inflation misallocates resources. For example, inflation may lead to an increase in the variability of relative prices and it is often claimed that this increase in variability leads to a misallocation of resources. This claim raises the following empirical question, does inflation alter the composition of real output; that is, does it change real output shares? We examine this question using dynamic panel data methods for nine sector panels each with seven OECD countries from 1970 to 2005. We find evidence that inflation changes the real shares of some sectors even when inflation is treated as endogenous.     

Stochastic convergence of per capita carbon dioxide emissions and multiple structural breaks in OECD countries

This research applies an innovative panel data stationarity testing procedure developed by Carrion-i-Silvestre et al. [Carrion-i-Silvestre, J.L., Barrio-Castro, T.D. and Lopez-Bazo, E., 2005. Breaking the panels: An application to the GDP per capita, Econometrics Journal 8, 159–175.], which has the advantage of recognizing multiple structural breaks and the presence of cross-section dependence in order to re-investigate the hypothesis that per capita carbon dioxide (CO₂) emissions stochastically converge for 21 OECD countries from 1950 to 2002. Remarkably, the evidence clearly indicates that the panel dataset of relative per capita CO₂ emissions is stationary after the structural breaks and cross-sectional dependence are introduced into the model. These findings offer strong policy implications for governments, regardless of whether they are in “convergent group” or “divergent group” countries. We also find that the structural breaks in the 1960s and over the 1970–1982 period are associated with time periods of fossil fuel becoming the main source of productivity, higher oil prices, and the development of nuclear power.     

Nominal rigidities, skewness and inflation regimes

The menu-costs model developed by Ball and Mankiw (BM) [Ball, L., Mankiw, N.G., 1994. Asymmetric price adjustment and economic fluctuations. Economic Journal 104 (423), 247–261; Ball, L., Mankiw, N.G., 1995. Relative-Price Changes as Aggregate supply shocks. Quarterly Journal of Economics 110 (1), 161–193] predicts that inflation is positively related to the skewness of price changes distribution. We test this prediction in different inflationary contexts: Spain (1975–2002) and Argentina (1960–1989). We find a positive inflation–skewness relationship in both countries at low inflation, even though the mean annual inflation rates were very different: 2.2% for Spain and 23% for Argentina. Therefore, the threshold of low inflation under which the menu-costs model is suitable is determined endogenously, and it depends on the inflationary experience of each economy. In the higher inflation periods skewness is not significant. Finally, our results suggest that the menu-costs model is not suitable beyond certain threshold of inflation.     

Threshold Effects of Inflation on Economic Growth: Is Africa Different?

This study examines nonlinearities in the inflation-growth nexus in Africa. The study employs a novel dynamic panel threshold regression method developed by Kremer et al. [(2013). Inflation and growth: New evidence from a dynamic panel threshold analysis. Empirical Economics, 44, 861–878. doi:10.1007/s00181-012-0553-9] that extends Hansen’s [(1999). Threshold effects in non-dynamic panels: Estimation, testing, and inference. Journal of Econometrics, 93, 345–368. doi:10.1016/S0304-4076(99)00025-1] non-dynamic panel threshold model as well as Caner and Hansen [(2004). Instrumental variable estimation of a threshold model. Econometric Theory, 20, 813–843. doi:10.1017/S0266466604205011] cross-sectional threshold model to deal with potential endogeneity problems. The findings of this study confirm a non-linear relationship between inflation and economic growth in Africa. More specifically, the results show that the inflation threshold values are 6.7% for the whole sample, 9% for the sub-sample of low-income countries and 6.5% for middle-income countries. The regression results suggest that relatively lower level of inflation appears to be in favor of higher economic growth only in African middle-income countries. However, inflation rate beyond a certain threshold is more likely to be detrimental to economic growth for all the cases. These results are robust by considering additional control variables and using three-year averages of the data. The findings of this study may be useful to African monetary policymakers as they decide on inflation targets to adopt to avoid the detrimental effects of high inflation while reaping the growth benefits of low inflation.     

The case for a “productivity norm”: Comment on Dowd

Instead of aiming for zero inflation, a “productivity norm” would allow permanent changes in the price level reflecting opposite changes in productivity or unit costs of production. Dowd (1995) disputes my claim that a productivity norm would be more conducive to macroeconomic stability than a stable price level. But Dowd's arguments succeed in undermining the case for a productivity norm only to the extent that they also undermine his own case for zero inflation.     

The lag from money to prices

This note accepts Terry Seaks's critique of my earlier method of estimating the lag between monetary growth and inflation by using percent changes over time spans of three or four years. However, Seaks's critique does not impair the main findings of this early work, which have been confirmed by several recent studies that avoid the pitfalls emphasized by him. These findings are that monetary growth has been a major determinant of inflation in a large number of countries since the late 1950s, and that money typically influences prices with lags of a year and a half or more.
