The effect of inflation uncertainty on inflation: Stochastic volatility in mean model within a dynamic framework

This paper investigates the effect of inflation uncertainty innovations on inflation over time by considering the monthly United States data for the time period 1976–2006. In order to investigate the effect of inflation uncertainty innovation on inflation, a Stochastic Volatility in Mean model (SVM) has been employed. SVM models are generally used to capture the innovation to inflation uncertainty, which cannot be achieved in the framework of popular deterministic ARCH type of models. Empirical evidence provided here suggests that innovations in inflation volatility increases inflation persistently. This evidence is robust across various definitions of inflation and different sub-periods.     

Population ageing and inflation with endogenous money creation

This paper models a mechanism through which population ageing may induce a deflationary process. We propose an overlapping-generations model (OLG) with money created by credits (inside money) and intergenerational trade. The model links demographic factors, such as fertility rates and longevity, to prices. We show that lower fertility rates lead to smaller demand for credit and lower money creation, which in turn cause a decline in prices. Changes in longevity affect prices through real savings and the capital market. Furthermore, a few links between interest rates and inflation are addressed; they arise in the general equilibrium and are not thoroughly discussed in literature. Long-run results are derived analytically; short-run dynamics are simulated numerically.     

On the real effects of inflation and inflation uncertainty in Mexico

We estimate an augmented multivariate GARCH-M model of inflation and output growth for Mexico at business cycle frequencies. The main findings are: (1) inflation uncertainty has a negative and significant effect on growth; (2) once the effect of inflation uncertainty is accounted for, lagged inflation does not have a direct negative effect on output growth; (3) However as predicted by Friedman and Ball, higher average inflation raises inflation uncertainty, and the overall net effect of average inflation on output growth in Mexico is negative. That is, average inflation is harmful to Mexican growth due to its impact on inflation uncertainty. (4) The Mexican Presidential election cycle significantly raises inflation uncertainty both during the year of the election and the year following the election which has correspondingly negative effects on output growth.     

Optimal trade policy in tariff games with inside money

We construct a bilateral trade model incorporating two physical goods and a financial asset (inside money) to discuss the optimal trade policy that countries would choose to maximize their respective utilities. In this Nash tariff game, the trade of physical commodities only occurs geographically across countries, and the trade of inside money allows for intertemporal allocation of consumptions. When the preferences, present and future endowments for each country are given, according to our numerical analysis, trade surplus or deficit (inside money) and optimal tariff rates are endogenously determined when general equilibrium conditions hold. One country may purchase inside money to shift current consumption to the future, and the other may be willing to issue inside money for smoothing its consumptions in two periods. This imbalance trade contradicts traditional trade models which imply a balanced trade policy. We further find that the price of inside money as an implied interest rate also is determined by the trade intervention policies.     

An augmented P-star model of Indian inflation

ABSTRACT

An augmented P-Star model is estimated and tested to identify the drivers of inflation in India. The model includes monetary and non-monetary factors, demand-pull and cost-push factors, and domestic as well as foreign factors. The results show that inflation in India is driven by a combination of monetary factors and non-monetary factors, some of which affect inflation on the supply side while others operate on the demand side. It turns out, however, that inflation in India is determined more by domestic rather than foreign factors.     

The dynamics of persistence in US inflation

Using a recently developed time-series approach, we show that post-WWII US inflation became highly persistent during the ‘Great Inflation’ period, and then switched back to a low persistence process during 1984, and has remained stationary until the present day.     

Evaluating inflation persistence considering model uncertainty and structural break

There is little consensus about the historical change in inflation persistence. One of the reasons is that researchers cannot choose a uniform model structure due to model uncertainty. In this study, a model to investigate inflation persistence is proposed. Unlike previous studies, I try to overcome model uncertainty by being agnostic about the structure of the model. Estimation results indicate that inflation has become less persistent over time, implying that inflation persistence is related to the way how monetary policy is conducted.     

The time-varying effect of inflation uncertainty on inflation for Turkey

We investigate the effect of inflation uncertainty on inflation from January 1982 through March 2016 for Turkey by using the Stochastic Volatility in Mean model with time-varying parameters. Our empirical evidence from consumer price index (CPI) inflation suggests that the observed positive relationship between inflation and inflation uncertainty is not robust. This positive relationship diminishes after 2002. This finding is valid for all five subcomponents of CPI inflation; however, for Health Services, Transportation Services, and Recreational and Cultural Services, an inflation-positive association is reported after 2010.     

Dynamic asset allocation and consumption under inflation inequality: The impacts of inflation experiences and expectations

Differences in spending patterns and in price increases across goods and services lead to the unequal inflation experiences of households (called inflation inequality). These differences then cause disagreements in inflation expectations and eventually have a significant effect on households’ asset allocation and consumption decisions. The asset allocation model in this paper explains how inflation experiences affect household investment and consumption through corresponding inflation expectations, which are characterized by long-term expected inflation, the impact coefficient of the expected inflation and the correlation between expected inflation and the risky return. Using China's economic data, the empirical results show that significant differences in inflation expectation arise from income gap, regional inequality, different inflation measures and economic sector spending differences. Using the estimated coefficients, the calibration results have policy implications that households need more financing channels to resist inflation, especially in rural areas and in the raw material sector.     

Expected inflation, expected stock returns, and money illusion: What can we learn from survey expectations?

We show empirically that survey-based measures of expected inflation are significant and strong predictors of future aggregate stock returns in several industrialized countries both in-sample and out-of-sample. Empirically discriminating between competing sources of this return predictability by virtue of a comprehensive set of expectations data, we find that money illusion seems to be the driving force behind our results. Another popular hypothesis – inflation as a proxy for aggregate risk aversion – is not supported by thedata.     

Optimal monetary and fiscal policies in a search theoretic model of monetary exchange

Search models of monetary exchange commonly assume that terms of trade in anonymous markets are determined via Nash bargaining, which generally causes monetary equilibrium to be inefficient. Bargaining frictions add to the classical intertemporal distortion present in most monetary models, whereby agents work today to obtain cash that can be used only in future transactions. In this paper, we study the properties of optimal fiscal and monetary policy within the framework of Lagos and Wright (2005). We show that fiscal policy can be implemented to alleviate underproduction while money is still essential. If lump sum monetary transfers are available, a production subsidy can restore the efficiency of monetary equilibria. The Friedman rule belongs to the optimal policy set, but higher inflation rates are also possible. When lump-sum monetary transfers are not available, equilibrium allocations are generally not first-best. Nevertheless, fiscal policy still results in substantial welfare gains. Money can be extracted from circulation via a sales tax on decentralized market activities, and the Friedman rule is only optimal if the buyer has relatively low bargaining power.     

Conflict inflation: estimating the contributions to wage inflation in Australia during the 1990s

One of the major emerging macroeconomic problems during thepast century has been the tendency for inflation to accelerateunder prolonged periods of full employment. According to Isaacand Kaldor, this arises because the three major objectives ofwage earners often conflict. The first objective is the desireto maintain relativities; the second is the desire to have a‘fair’ share of companies' profits; and the thirdis a reluctance to allow any encroachment on achieved standardsof living owing to unfavourable (exogenous) events. This papertests how well these three objectives explain wage inflationin Australia using a pseudo-panel data based on the period 1989–2000.The authors find that wages are sensitive to the three majorobjectives, but not to occupational unemployment rates.     

Inflation and inflation uncertainty in China

The study examines the relationship between inflation and inflation uncertainty in China using Generalized Autoregressive Conditional Heteroscedasticity model. Particularly, this link is investigated in China’s urban and rural sectors, motivated by the substantial urban–rural divide. The results provide strong statistical supportive evidence that higher inflation raises inflation uncertainty. On the other hand, evidence on the effect of inflation uncertainty on inflation is mixed depending on the sample periods and areas examined. The understanding of inflation-uncertainty nexus in China could provide implications to policymakers in the adoption of monetary policies.     

Nominal uncertainty and inflation: The role of European union membership

We provide evidence that higher inflation uncertainty leads to higher inflation in the new European Union (EU) member states and candidate countries only prior to EU accession. During EU accession and entry, inflation uncertainty has no effect on mean inflation.     

Understanding the dynamics of labor shares and inflation

Calvo-style models of nominal rigidities currently provide the dominant paradigm for understanding the linkages between wage and price dynamics. Recent empirical implementations stress the idea that these models link inflation to the behavior of the labor share of income. Ga?´ et al. (2001) argue that the model explains the combination of declining inflation and labor shares in Euro area. In this paper, we show that with realistic parameters, the canonical Calvo-style model cannot explain the joint behavior of inflation and the labor share in Europe. In addition, we show that the model fails very badly in sectoral data with consistently negative estimated coefficients on the labor share in a number of different inflation specifications. Indeed, the use of a traditional output gap measure proved more successful in terms of a positive relationship with inflation.     

A simple analytical model of the adverse real effects of inflation

Abstract

The essential insight advanced in this paper is that the claim that inflation can impair growth makes most sense in the context of a monetary production economy, wherein a role for money in the determination of real activity is posited from the very start. We construct a model of inflation and growth that distinguishes between the properties of various qualitatively different inflation regimes. It is then shown how some of these regimes, by undermining confidence in various nominal contracts that are central to the process of accumulation in a monetary production economy, can adversely affect growth.     

Stepping on a rake: The role of fiscal policy in the inflation of the 1970s

The inflation of the 1970s in the US is often discussed as if the only type of policy action that could have prevented the inflation were monetary policy actions and the only type of policy errors that might have induced the inflation were monetary policy errors. Yet fiscal policy underwent dramatic shifts in the 1970s and economic theory makes clear that in an environment of uncertainty about future fiscal policy, monetary policy instruments may lose potency or have perverse effects. This paper documents the vagaries of fiscal policy in this period and argues that people at the time must have been uncertain about fiscal policy's future course. It also lays out a theoretical framework for understanding the effects of fiscal uncertainties on monetary policy and shows that fiscal variables have predictive value in dynamic models, even if traditional monetary policy indicators are included in the system.     

A persistence-weighted measure of core inflation in the Euro area

We propose a new core inflation measure for the Euro area which places the emphasis on the more lasting, i.e. persistent, price developments at a disaggregated level. The importance of each component of the HICP is reweighted according to its relative persistence, as measured by the sum of the autoregressive coefficients or by an indicator of mean reversion. Unlike headline inflation, our baseline core inflation measure is highly correlated with ECB monetary policy decisions, which could mean that they contain ex ante (pre monetary policy) information on inflationary pressure.     

Identifying fiscal inflation

Fiscal theorists warn about the risk of future inflation as a consequence of fiscal imbalances in the US. Because actual inflation remains historically low and data on inflation expectations do not corroborate such risks, warnings for fiscal inflation are often ignored in policy and academic circles. This paper shows that a canonical NK-DSGE model enables identifying an anticipated component of inflation expectations that is closely related to fiscal policy. Estimation results suggest that fiscal inflation concerns have induced a 1.6%-points increase in long-run inflation since 2001. The model also rationalizes why data on inflation expectations do not reveal such concerns outright.
