Determinacy with nominal assets and outside money

Summary. We build a finite horizon model with inside and outside money, in which interest rates, price levels and commodity allocations are determinate, even though asset markets are incomplete and asset deliveries are purely nominal.Received: 2 July 2003, Revised: 1 December 2004 JEL Classification Numbers: D50, E40, E50, E58.Correspondence to: J.

Inside and outside fiat money, gains to trade, and IS-LM

Summary. We build a one-period general equilibrium model with money. Equilibrium exists, and fiat money has positive value, as long as the ratio of outside money to inside money is less than the gains to trade available at autarky. We show that the nominal effects of government fiscal and monetary policy can be completely described by a diagram identical in form to the IS-LM curves introduced by Hicks to describe Keynes' general theory. IS-LM analysis is thus not incompatible with full market clearing, multiple commodities, and heterogeneous households. We show that as the government deficit approaches a finite threshold, hyperinflation sets in (prices converge to infinity and real trade collapses). At the other extreme, if the government surplus is too large, the economy enters a liquidity trap in which nominal GNP sinks and monetary policy is ineffectual.

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.     

The election cycle in the inflation bias: evidence from the G-7 countries

This paper derives and evaluates empirical implications which separate the naive voters view [Nordhaus, W.D., 1975. The political business cycle. Review of Economic Studies 42, 169–190.] from the rational-voters view [Barro R., Gordon, D., 1983. Rules, discretion, and reputation in a model of monetary policy. Journal of Monetary Economics 12, 101–121.] under rational expectations. The observational equivalence of the two approaches obtained under a natural rate vanishes as output persistence is introduced. An analysis of inflation in the G-7 countries reveals election patterns supporting the joint hypothesis that demand shocks persist and that monetary policy courts retrospective voters. Patterns turn weaker as central banks become more independent, but do not disappear. Reducing inflationary bias not only requires more central bank independence, but as well less persistence.     

Sectoral variability and the foundations of optimal inflation rate

The recent monetary search models argue that the real effects of inflation on economic activity can be gauged through relative price variability (RPV). Our study uses a large panel data of 32 developed and emerging European economies to test the relationship between inflation and RPV. We use a panel threshold model to explore the regime-specific effects of inflation on RPV. Our results confirm a non-linear profile of the relationship between inflation and RPV. Consistent with the monetary search models, our results show that the effects of inflation on the RPV are more significant in its low (below 0.792% per annum) and high (beyond 2.064% per annum) regimes. Finally, we also report a strong moderating role of central bank independence (CBI) in the inflation–RPV relationship.     

信贷资金配置的市场化程度分析

尽管政府取消了对银行贷款规模的直接控制,改成了对银行的贷款进行窗口指导管理,但在实际操作中,政府对信贷资金的分配仍然有十分强大的控制权.为了考察当前我国信贷市场资金分配的市场化程度,本文以最近五年的宏观金融统计数据,采用了协整检验、向量误差修正模型、Granger因果检验等计量方法验证了我国贷款资金分配的市场化程度.结论表明,当前我国信贷资金分配的市场化程度较低,非市场因素在影响信贷资金的分配中仍占主导作用.     

Deficit sustainability and inflation in EMU: An analysis from the Fiscal Theory of the Price Level

Price determination theory typically focuses on the role of monetary policy, while the role of fiscal policy is usually neglected. From a different point of view, the Fiscal Theory of the Price Level takes into account monetary and fiscal policy interactions and assumes that fiscal policy may determine the price level, even if monetary authorities pursue an inflation targeting strategy. In this paper we try to test empirically whether the time path of the government budget in EMU countries would have affected price level determination. Our results point to the sustainability of fiscal policy in all the EMU countries but Finland, although no firm conclusions can be drawn about the prevalence of either monetary or fiscal dominance.     

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.     

Endogenous skill heterogeneity and inflation

This paper examines the implications of ex ante skill heterogeneity for long run inflation. We develop a dynamic general equilibrium model in which there are two types of labor (skilled and unskilled), two types of capital (human and physical), and money is introduced via a cash in advance constraint on consumption purchases. Skill heterogeneity is characterized in terms of (i) a parameter governing the ease with which the two types of labor can be substituted for each other in production; and (ii) the “productivity” of human capital in the production of skill. The model includes the accumulation of human capital which in turn creates skill heterogeneity among workers through an efficiency wage mechanism. Numerical experiments indicate that there is a range of parameter estimates in which the Friedman Rule may not be optimal. Furthermore, our quantitative experiments also indicate that there is a range of parameter values in which a greater degree of skill heterogeneity may be associated with a greater preference for inflation. Empirically, we also find that the inflation and heterogeneity correlation is positive.     

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.     

Openness, income-tax progressivity, and inflation

This paper considers a model of an open economy in which the degree of income-tax progressivity influences the interaction among openness, central bank independence, and the inflation rate. Our model suggests that an increase in the progressivity of the tax system induces a smaller response in real output to a change in the price level. This implies that increased income-tax progressivity reduces the equilibrium inflation rate and that the effect of increased income-tax progressivity on inflation is smaller when the central bank places a higher weight on inflation or when there is greater openness. Examination of cross-country inflation data provides empirical support for these key predictions.     

信贷量经济效应的期限结构研究

银行信贷和经济波动的关系一直是理论和实务界关注的焦点,过去国内的研究大多仅从信贷总量层面入手而忽视了结构效应,这不利于厘清信贷在经济中的作用机理。在将贷款按期限划分为短期贷款和中长期贷款后,本文通过应用一个小型DSGE模型,发现短期贷款对经济增长虽有短期的促进作用,但却形成通货膨胀压力;而中长期贷款对经济增长有长期的促进作用,同时对通货膨胀有一定的抑制作用。以我国1998-2010年的宏观数据为样本进行的FAVAR检验支持了上述观点。该结论一方面意味着信贷政策及其监管应加强对信贷期限结构的关注,另一方面结合我国近年来中长期贷款比重大幅上升的客观事实,也从一个新的视角解释了货币信贷加速扩张的同时,价格水平却较为稳定的"中国货币之谜"。     

Pricing in debit and credit card schemes

This paper presents a model of a debit or credit card payment scheme, providing a simple determination of the socially optimal structure of fees between those charged to cardholders and those charged to merchants.     

Openness, centralized wage bargaining, and inflation

This paper develops a model of an open economy containing both sectors in which wages are market-determined and sectors with wage-setting arrangements. A portion of the latter group of sectors coordinate their wages, taking into account that their collective actions influence the equilibrium inflation outcome in an environment in which the central bank engages in discretionary monetary policymaking. Key predictions forthcoming from this model are (1) increased centralization of wage setting initially causes inflation to increase at low degrees of wage centralization but then, as wage centralization increases, results in an inflation drop-off; (2) a greater degree of centralized wage setting reduces the inflation-restraining effect of greater central bank independence; and (3) increased openness is more likely to reduce inflation in nations with less centralized wage bargaining. Analysis of data for seventeen nations for the period 1970–1999 provides generally robust empirical support for all three of these predictions.

Announcements and credibility under inflation targeting

We inspect how inflation target announcements are instrumental in building central bank credibility and shaping inflation expectations. Investigating the role of announcements by using a time varying credibility measure, we find that both the accuracy and the frequency of inflation announcements have a positive impact on how much attention the public pays to target announcements.
