Can inflation targeting reduce price information asymmetry and alleviate corruptive behavior? Evidence from developing countries

This paper examines the role of inflation targeting as a price signaling mechanism reducing price information asymmetry and potentially reducing incentives for corruptive actions through its direct control on the inflation rate, thus simultaneously increasing institutional quality. The obtained evidence suggests that adopting inflation targeting lowers corruption in a sample of 61 developing countries for the period between 1990 and 2018. Countries that have adopted inflation targeting experience lower corruption levels, as measured by the corruption perceptions (CP) index, controlling for other relevant determinants of corruption identified in the empirical literature, such as inflation, level of income, income distribution, trade openness and the rule of law. This result is sensitive to the type of inflation targeting adopted. Soft (unofficial) inflation targeting has no significant effect on the corruption level, giving support to the claim that strong institutional commitment, accompanied by transparency and constant communication with regards to inflation targets by the central bank, provides an adequate price signaling mechanism. In addition, the analysis provides evidence that an efficient rule of law reduces corruption levels significantly, although its effects are rather modest to support the claims that it can solely lessen corruptive behavior in the sample of developing countries.     

对中国通货膨胀的实证研究——从一般到特殊的建模方法

本文采用从一般到特殊的建模方法,利用PcGets软件,实证考察了1994~2009年中国通货膨胀与货币供应、产出缺口、汇率和国际原油价格之间的联系。研究表明,通货膨胀和货币供应之间存在长期稳定的正相关关系,但通货膨胀并不完全是货币现象。除货币供应外,还有其他更多重要变量共同决定通货膨胀的变化。产出缺口与通货膨胀之间存在显著关系,因而不能忽视汇率因素对通货膨胀的影响等。     

A new look at variation in employment growth in Canada: The role of industry,provincial, national and external factors

We examine fluctuations in employment growth using Canadian data from 1976 to 2010. We consider a wide range of models and examine the sensitivity of our findings to modelling assumptions. The results from our most preferred model, which we selected using the Bayesian Information Criteria, indicate that most of the variance in employment growth that is not due to the idiosyncratic error comes from domestic sources, with most of this coming from industry and provincial factors. Overall, we find that external and national factors play a much smaller role in employment fluctuations than in earlier research. We provide some possible explanations for these differences and discuss the implications of our findings for public policy and theory.     

Inflationary equilibrium in a stochastic economy with independent agents

We prove the existence of stationary monetary equilibrium with inflation in a “Bewley” model with constant aggregate real variables but with idiosyncratic shocks to the endowments of a continuum of individual agents, when a central bank stands ready to borrow or lend fiat money at a fixed nominal rate of interest and the agents face borrowing constraints. We also find that, in the presence of real micro uncertainty about individual endowments, the rate of inflation is higher (equivalently, the real rate of interest is lower) than it would be in a “certainty-equivalent economy”; to wit, one in which every agent’s endowment is replaced by its expected value. Thus, underlying microeconomic uncertainty and borrowing constraints are shown to generate additional inflation.     

通货膨胀传导机制研究——基于货币供给和经济增长的视角

通货膨胀管理是宏观经济的重要内容,通货膨胀、货币供给和经济增长之间互相影响、互相制约。本文利用中国2005年1月～2010年3月度数据构建模型分析,得出结论:(1)短期影响消费者物价指数的因素主要是国内生产总值增长率,长期控制消费者物价指数上涨的要素主要是货币的供给;(2)宏观经济形势稳定条件下通货膨胀、货币供给和经济增长之间具有长期协整关系;(3)消费者物价指数对自身的波动具有较强的累积效果,经济增长贡献了消费者物价指数波动的55%,而广义货币的这一比例仅为18%;(4)中国货币收入的真实需求弹性为1.152,这一数据远高于发达国家的水平。文章最后给出了相应的政策性建议。

An index aggregation approach to comparing the overall performance of emerging and developed countries

An index aggregation approach is proposed to carry out comparisons of BRICSAM, a populous rapidly growing economic group consisting of Brazil, Russia, India, China, South Africa, Association of South-East Asian Nations (ASEAN), and Mexico with Group of Seven (G7), the most developed country club including Canada, France, Italy, Japan, Germany, United Kingdom and the United States. It is estimated that by 2050 the accelerated economic activity of BRICSAM could have significant impact on investment flows, legal and regulatory frameworks, the stability of political institutions, human capital and migration flows, competition policy, intellectual property rights, and social and environmental policies. The comparison analyses of BRICSAM and G7 countries could assist people to better understand the status quo of these countries in the global economy and international system, particularly in the areas of economics and responsible activities such as sustainable development, global commitments and transparent practices. Many country-ranking indices, such as the indices given in the global competitiveness report by the World Economic Forum, and the environmental sustainability index by Yale University, constitute evaluations of countries from different perspectives. This paper proposes a data envelopment analysis-based approach to aggregate different ranking indices for BRICSAM and the G7 countries. The approach can provide a fair overall assessment of a country's standing by maximizing its possibility of obtaining the best possible result.     

Inflation aversion in transition countries: Empirical evidence from the Baltic States

In command economies, inflation is either absent or at least unrelated to supply and demand. However, when the economies in Eastern Europe started transforming into market economies, they suddenly experienced high and volatile inflation rates. Transformation countries are therefore interesting laboratories for studying individual inflation aversion. In this paper we study the level and determinants of individual inflation aversion in the three Baltic countries. Using data from 11 waves of the Eurobarometer survey, we find age, education and the macroeconomic situation to have significant effects on the likelihood to mention inflation among the most important problems facing the country. Moreover, we find the populations of all three Baltic countries to be significantly more inflation averse than the population of the United Kingdom, a western democracy with a long tradition as a market economy. We attribute this finding to the specific experiences of the Baltic populations with inflation.     

我国灵活动态金融状况指数构建与应用研究

鉴于目前研究缺乏灵活动态性,本文从通胀控制目标出发,引进MI-TVP-SV-VAR模型,选取5个金融变量,估计其每一期的灵活动态权重,构建我国灵活动态金融状况指数,并分析它对通胀率的预测能力。经验分析结果表明利率和房价的权重相对较大,反映出货币政策依然倚重于价格型传导渠道;FCI与通货膨胀有很高的相关性,且领先通胀1~7个月,能够很好地预测通胀。建议政府定期构建我国灵活动态金融状况指数并应用于通货膨胀预测。     

How should monetary policy respond to changes in the relative price of oil? Considering supply and demand shocks

This paper examines optimal monetary policy in a New Keynesian model where supply and demand shocks affect the price of oil. Optimal policy fully stabilizes core inflation when wages are flexible. The nominal rate rises (falls) in response to the demand (supply) shock. With sticky wages core inflation falls (rises) in response to the demand (supply) shock. Impulse response functions from a VAR estimated with post-1986 U.S. data show minimal movement in core inflation in response to both shocks. The federal funds rate rises (falls) in response to the demand (supply) shock, consistent with the predictions from the theoretical model for policy that stabilizes core inflation.     

Macroeconomic shocks and fluctuations in African economies

We estimate a monetary DSGE model to examine the role of macroeconomic shocks in generating fluctuations in ten African countries. The model is estimated with the Bayesian technique using twelve macroeconomic variables. The findings indicate that both the internal and external shocks significantly influence output fluctuations in African economies. Over a four quarter horizon, internal shocks are dominant and over eight to sixteen quarter horizons, external shocks are dominant. Among the external shocks, external debt, exchange rate, foreign interest rate and commodity price shocks account for a large part of output variations in African economies. Money supply and productivity shocks are the most important internal shocks contributing to output fluctuations in African countries.     

Addressing the growth failure of the oil economies: The role of financial development

The oil exporting countries have experienced a relatively continuous fall in GDP per capita over the last 30 years. This is in spite of benefiting from a more than average of the rest of the world investment rate. The findings of this paper, report a lower level of financial development for the oil economies when compared with the rest of the world. We will show in this paper that the higher rate of investment of the oil economies can be explained mainly by the oil revenues and surprisingly, financial development has a net dampening effect on investment for these economies. The paper also shows that the weakness of financial institutions, contributes to the poor performance of economic growth of the oil economies and the weakness of financial institutions might be associated with the dominant role of government in total investment and the weakness of private sector.     

Money demand and the role of monetary indicators in forecasting euro area inflation

This paper examines the stability of money demand and the forecasting performances of a broad monetary aggregate (M3), excess liquidity and excess inflation in predicting euro area inflation. The out-of sample forecasting performances are compared to a widely used alternative, the spread of interest rates. The results indicate that the evolution of M3 is still in line with money demand, even when observations from the economic and financial crisis are included. Both excess measures and the spread are useful for predicting inflation.     

Oil price shocks and unemployment in Central and Eastern Europe

The aim of this paper is to examine the effect of oil price movements on unemployment in Central and Eastern Europe. We do this by disentangling oil prices movements by their sign and from there we analyse the separate effects of positive and negative movements of oil prices on unemployment rates. We find that, although oil prices and unemployment are not correlated very much in the short run, the effect of oil price shocks on the natural rate of unemployment goes in the same direction, so that increases or decreases in oil prices increase or decrease the natural rate of unemployment.
