Are inflation expectations rational?

Several recent papers report evidence of an apparent statistical bias in inflation expectations and interpret these findings as overturning the rational expectations hypothesis. In this paper, we investigate the validity of such an interpretation. We present a computational dynamic general equilibrium model capable of generating aggregate behavior similar to the data along several dimensions. By construction, model agents form “rational” expectations. We run a standard regression on equilibrium realizations of inflation and inflation expectations over sample periods corresponding to those tests performed on actual data and find evidence of an apparent bias in inflation expectations. Our experiments suggest that this incorrect inference is largely the product of a small sample problem, exacerbated by short-run learning dynamics in response to infrequent shifts in monetary policy regimes.     

Unexpected inflation and bank stock returns: The case of France 1977–1991

This paper evaluates the impact of unexpected inflation on the stock returns of a sample of French banks. It offers an empirical test of theories that have predicted an impact of inflation on the stock returns of banks. The paper complements a large literature that has focused exclusively on the impact of unexpected interest rates. The analysis provides empirical support to the hypothesis that, in periods of volatile inflation, there exists an inflation risk factor which is independent of the well-documented interest rate factor.     

Foreign trade shocks and the dynamics of high inflation: Israel, 1978–1985

The purpose of this paper is to provide empirical answers to questions related to the propagation of shocks in a high-inflation economy. Do one-time shocks give rise to long-term persistence of inflation? Do foreign trade shocks trigger a process that, through indexation and monetary accomodation, results in long-term changes in inflation? Within the context of a specific hypothesis, influential both in policy discussions and in economic analyses, the paper addresses these issues using Israeli data and vector-autoregression techniques. The evidence does not support the hypothesis from the ‘inertia approach’ that one-time nominal shocks have a persistent effect on the inflation rate, or the hypothesis that long-term changes in inflation are triggered by autonomous fluctuations in the trade deficit.     

Can aggregation explain the persistence of inflation?

An aggregation exercise is proposed that aims at investigating whether the fast average adjustments of the disaggregate inflation series of the euro area CPI is coherent with the slow adjustment of euro area aggregate inflation. Estimating a dynamic factor model for 404 inflation sub-indices of the euro area CPI allows to decompose the dynamics of inflation sub-indices into a part due to a common macroeconomic shock and to sector specific idiosyncratic shocks. Although idiosyncratic shocks dominate the variance of sectoral prices, one common factor appears to be the main driver of aggregate dynamics. In addition, the heterogenous propagation of this common shock across sectoral inflation rates, and in particular its slow propagation to inflation rates of services, generates the persistence of aggregate inflation. We conclude that the aggregation mechanism explains a significant amount of aggregate inflation persistence.     

Do monetary indicators lead euro area inflation?

This paper assesses based on euro area data whether the strong in-sample long-run link between money growth and inflation that has been highlighted by a number of recent empirical studies is exploitable to predict inflation out of sample. The results from standard bivariate forecasting models suggest that no monetary (nor any other) single indicator significantly outperforms a simple benchmark forecast. The further analysis shows that it would be premature however to discard based on such evidence the usefulness of monetary (and all other) indicators. First, it is shown that based on judgemental adjustments to monetary indicators correcting for the effects of identifiable, persistent velocity shifts, it appears possible to significantly improve predictive ability in real time. Second, I find that a factor forecasting model combining monetary and economic indicators, which can be regarded as a generalized quantity theory- or two-pillar Phillips Curve-forecasting model, delivers a fairly good and stable forecasting performance.     

Are equities good inflation hedges? A frequency domain perspective

By using industry level data, we examine the relation between equity returns and inflation in a frequency dependent framework. Our analysis shows that a positive relation in fact exists between equity returns and high frequency inflation shocks for commodity and technology related industries. Since higher frequency shocks are independent from trend and are transitory in nature, our findings imply a positive relation between stock returns and the unexpected component of inflation. Furthermore, we show that the results are robust to firm-level data by using a sample from the oil industry. Hence, our study provides a new look at the impact of inflation on equities by showing the sensitivity of conclusions in prior work to frequency dependence in data.     

How much inflation is necessary to grease the wheels?

Tobin's proposition that inflation “greases” the wheels of the labor market is studied using a simple dynamic stochastic general equilibrium model with asymmetric wage adjustment costs. The simulated method of moments is used to estimate the nonlinear model based on its second-order approximation. Optimal inflation is determined by a benevolent government that maximizes the households’ welfare. Econometric results indicate that nominal wages are downwardly rigid and that the optimal level of grease inflation for the U.S. economy is about 0.35% per year, with a 95% confidence interval ranging from 0.04% to 0.87%.     

Is gold a hedge against inflation? A wavelet time-scale perspective

Among the many presumed characteristics of gold, the ability to act as an enduring store of value is frequently noted. In this paper, the ability of gold to dynamically hedge against inflation is examined for various holding periods using the continuous wavelet transformation. Gold is first established as both a short- and long-term hedge against realized inflation for a number of developed economies. Dynamic analysis demonstrates that these hedging properties are not limited to a single historical cohort. Next, gold is shown to comove with unexpected inflation across all countries examined, albeit with some variation in the direction of the relationship. Finally, the capacity of both gold futures and gold stocks to act as a hedge against inflation is demonstrated.     

How important is the financial sector to price indices in an inflation targeting regime? An empirical analysis of the UK and the US

This paper investigates whether there are benefits in terms of higher economic stability from incorporating stock prices into the price index targeted by the central banks. It also looks into the question of whether central banks should use stock prices as a component of the output stability index and how the index can be constructed. An optimization technique is employed to estimate weights for the various sectoral prices. The obtained weights, which depend on sectoral parameters, differ from those used in the construction of the consumer price index, CPI. Using data from the UK and the US, our analysis demonstrates that in comparison to the CPI, our measure of inflation leads to a higher output stability. Thus, in an inflation-targeting monetary policy environment, it is important to adopt a broader inflation benchmark than the CPI for the general macroeconomic stability.     

Are common stocks a good hedge against inflation? Evidence from the Pacific-rim countries

We explore whether the observed real stock return–inflation relations in the U.S. and 10 Pacific-rim countries for the sample period of 1970–1997 can be explained by the interaction between real and monetary disturbances. Ten countries exhibit a negative relation between real stock returns and inflation. Malaysia is the only country that exhibits a positive relation. For nine countries, real output disturbances drive a negative stock return–inflation relation, while monetary disturbances yield a positive relation. In addition, real shock components appear to be relatively more important than monetary shock components for these countries, and as a result the observed relation between stock returns and inflation is negative. Neither the tax hypothesis nor the monetary regime hypothesis seems to be easily compatible with the diverse experiences of the Pacific-rim countries.     

A happy “half way-house”? Medium term inflation targeting in New Zealand

The 2002 Policy Targets Agreement (PTA) between the government and central bank of New Zealand asks the central bank to target inflation “over the medium term” rather than over an annual target. Delegating such a medium term objective to the central bank shifts inflation targeting towards a “halfway-house” between inflation targeting and price level targeting. We show empirically that this helps time consistent policy approximate the first-best commitment policy even when the government asks the central bank to weight output stabilisation differently to society. We estimate the New Zealand economy with a small open economy DSGE model and show that the happiest halfway house is located around a two year averaging horizon at most, which leads to mild improvements in monetary policy efficiency.     

The housing price boom of the late 1990s: Did inflation targeting matter?

The recent boom in the housing markets of most developed economies has spurred criticism that inflation targeting central banks may have neglected the build-up of financial imbalances. This paper provides a formal empirical test of such claims, using a standard program evaluation methodology to control for a possible bias due to self-selection into inflation targeting. We consider 17 industrial economies over the period 1980–2007, among which nine countries have targeted inflation at some point. We find robust evidence of a significant positive effect of inflation targeting on real house price growth and on the house price-to-rent ratio.     

Bias in Federal Reserve inflation forecasts: Is the Federal Reserve irrational or just cautious?

Inflation forecasts of the Federal Reserve seem to have systematically under-predicted inflation from the fourth quarter of 1968 until Volcker's appointment as Chairman, and to systematically over-predict it afterwards until the second quarter of 1998. Furthermore, under quadratic loss, commercial forecasts seem to have information not contained in those forecasts. To investigate the cause of this apparent irrationality, this paper recovers the loss function implied by Federal Reserve's inflation forecasts. The results suggest that the cost of having inflation above an implicit time-varying target was larger than the cost of having inflation below it for the period since Volcker, and that the opposite was true for the pre-Volcker era. Once these asymmetries are taken into account, the Federal Reserve's inflation forecasts are found to be rational.     

Apples and oranges? Corporate rescue and functional convergence in the US and UK

This paper challenges the standard characterisation that US law in the sphere of corporate bankruptcy is ‘pro debtor’ and UK law is ‘pro creditor’. It suggests that the traditional thesis is, at best, a potentially misleading over‐simplification. It also offers the conclusion that there is functional convergence in practice, while acknowledging that corporate rescue, as distinct from business rescue, still plays a larger role in the US. The functional convergence has partly come through the UK Enterprise Act 2002 but the paper suggests that the main move has been that of US law and practice in a UK direction with more emphasis on business disposals and speedier cases than on corporate reorganisations, as traditionally understood. This mirrors practice in the UK where the emphasis has always been on business disposals. Unfortunately, the current economic recession on both sides of the Atlantic has shone a heightened spotlight on business bankruptcy and is likely to generate further changes in practice and ultimately legislation.

Partners and Competitors

The United States and China are entering an entirely new and complex era in their economic relationship. In a nutshell, China is both partner and competitor, and simplistic efforts to cast the complexity of U.S.-China economic relations as either one of partnership or competition are unhelpful to the development of     

Of stars and galaxies – Co-authorship network and research

We examine the association between network centrality and research using the accounting research community setting. We establish co-authorship network using papers published in the five top accounting journals from 1980 to 2016. We find that the co-authorship network in accounting is a “small world” with some most connected authors playing a key role in connecting others. We use machine learning to label published papers with multiple topics and find patterns in topics over time. More importantly, we find that co-authorship network centrality is positively associated with future research productivity and topic innovation and that the impact of centrality on productivity is higher with more senior authors. Further, centrality of an author’s co-authors also has an incrementally positive impact. We conclude that network centrality positively influences research output.     

Sand and Stone

A story goes that two friends were walking through a desert. During some point of the journey they had an argument, and one friend slapped the other one in the face. The one who got slapped was hurt. But without saying anything, he wrote in the sand with his finger： ＂TODAY MY BEST FRIEND SLAPPED ME IN THE FACE. ＂     

Sorting and comparing: Standard-setting and “ethical” categories

The Financial Accounting Standards Board (FASB) describes its public interest function as “…developing standards that result in accounting for similar transactions and circumstances in a like manner and different transactions and circumstances…in a different manner (Facts about FASB).” This statement implies that rule-makers possess an expertise that makes analogizing transactions or circumstances to other transactions or circumstances unproblematic. In this paper we utilize two instances of standard-setting, SFAS 123R and SFAS 143, to demonstrate from FASB's analogic reasoning in these cases that similarity and dissimilarity are not so easily ascertained. A judgment about similarity invariably involves ignoring some perspectives of similarity that would lead to substantially different conclusions about the appropriate accounting. We also illustrate via the two examples the inherent value judgments that underlie the conclusions reached by FASB and how these value judgments raise questions about the ethics of the current standard-setting process.
