A PANIC analysis on regional and sectoral inflation: the Spanish case

This article studies the stochastic properties of several inflation rates for the Spanish economy using the consumer price index (CPI) for the 17 regions and 12 groups of goods and services, and the producer price index (PPI) for 26 industrial sectors. To this end, we employ the panel analysis of nonstationarity in idiosyncratic and common components (PANIC) approach proposed by Bai and Ng (2004, 2010). This methodology enables us to decompose the observed inflation rate series into a common and an idiosyncratic component, thus allowing us to identify the exact source of nonstationarity. Our analysis provides strong evidence of the presence of a common stochastic trend driving the observed series forming the panel of CPI-based inflation rates for the regions. This, coupled with the presence of a jointly stationary idiosyncratic component, implies the existence of pairwise cointegration across the regional CPI-based inflation rates, which show a clear pattern of convergence over time. This gives an indication of increased geographical homogeneity in consumption patterns. The evidence for the panels of CPI-based inflation of groups of goods and services and PPI-based inflation of industrial sectors indicates the existence of four independent common stochastic trends. This, combined with jointly stationary idiosyncratic series, provides much weaker evidence of cross-cointegration for these two panels.     

Modelling inflation shifts and persistence in Tunisia: perspectives from an evolutionary spectral approach

This article examines the dynamic characteristics of the inflation rate in Tunisia over the last two decades, and particularly following the onset of the Arab Spring in 2010 which causes distortions in this country’s monetary policy. We focus on the two specific dimensions of the Tunisian inflation rate: inflation regimes and persistence. We tackle this issue by adopting an evolutionary spectral approach, initially proposed by Priestley and Tong (1973). Our main findings indicate a stable inflation regime in the last 10 years, with an average inflation rate of around 5.5%. It is also found that the Tunisian inflation experienced a high degree of inertia which reflects its gradual responses to shocks. We also discuss the policy implications of these results, which typically require policy-makers to implement sound institutional reforms to reduce inflation.     

国际资本流动对房地产价格的影响——基于中国的实证检验:1998-2006

Taking the inflation into consideration and making use of the quarter data of the actual foreign investment, housing and land prices in China from 1998 to 2006, this paper examines the relationship between housing prices and international capital flows using Error Correction Model (ECM) and Granger causality test. Results show that in the short run, the increase of housing prices attracts the inflow of foreign capitals; in the long run, foreign capitals help to boost the rise of housing prices. Therefore, at present, Chinese government must impose effective restrictions on the flow of foreign capital into the real estate market. __________ Translated from Caijing Wenti Yanjiu 财经问题研究 (Research on Financial and Economic Issues), 2007, (3): 55–61     

金融状况指数FCI与货币政策反应函数经验研究

文章运用VAR模型经验估计了中国的金融状况指数FCI,结果表明FCI指数对通货膨胀率具有良好的预测力。在此基础上,将FCI指数作为目标和信息变量纳入泰勒规则,运用GMM方法估计了中国的货币政策反应函数,发现FCI指数与短期利率存在正相关关系,可以成为货币政策的短期指示器;但是利率调节对CPI通胀率、产出缺口和金融形势的松紧变化均反应不足。特别是利率对金融形势松紧变化的调节不足,刺激了金融不平衡和资产价格泡沫的相互推动和累积,是经济不平稳发展的重要政策诱因。     

Consumption and disposable income in the EU countries: the role of wealth effects

We investigate the long run relationship between private consumption and disposable income for a sample of EU countries using recently developed panel cointegration techniques. For the ordinary consumption-income model the evidence on cointegration is ambiguous. In addition, the cointegration vector obtained by efficient estimation methods is not consistent with theoretical reasoning, as it reflects a decline in the savings rate over time. Extending the analysis by financial wealth improves the model fit markedly. In particular, the income elasticity is not different from 1 and therefore in line with the life cycle permanent income hypothesis. The marginal propensity to consume out of financial wealth is in a range of 3–5%, thereby confirming recent time series results.     

Empirical research on monetary policy,asset prices and inflation: an analysis based on provincial panel data in China

In this article, we investigate the dynamic correlations among monetary policy, asset prices and inflation and assess the regional effects of monetary policy in China for the period October 2007 to July 2013. We focus on the interdependencies among monetary policy and asset price fluctuations by using the Shanghai Interbank Offered Rate as the preferred variable for analysing monetary policy movement. In particular, we apply a vector autoregressive model in a panel setting, which allows researchers to examine variations over time or across individual regions. The empirical results presented herein indicate that monetary policy reacts actively to asset prices, although it is still shown to be ineffective. In addition, we find that asset prices display some regional differences in their response to an unexpected monetary policy shock.     

Decomposing household,professional and market forecasts on inflation: a dynamic factor model analysis

A dynamic factor model with stochastic volatility is used to investigate the relationships between three alternative measures of inflation expectations. The results show evidence of both a common time-varying trend and a common transitory component between inflation and short-term inflation expectations from households, professionals and markets. While the common time-varying trend has declined in both level and volatility since the early 1980s, it was found that consumer expectations are disproportionately influenced by the visibility of prices of select few goods. Roughly speaking, a 1% point increase in food and energy prices leads to about 1/3% point increase in consumer forecasts of inflation. In terms of policymaking, this finding suggests that stability in highly visible prices can moderate inflation in a meaningful way.     

Oil prices and economic activity: evidence for G-7 economies based on a wavelet approach

This study examines the relationship between oil prices and economic activity in the G-7 economies during the period 1960M1–2014M07 using a wavelet approach. The results show significant differences in the relationship between these two variables depending on the frequencies. Furthermore, we find that oil price shocks affect economic activity at low frequencies (long run) in all G-7 countries, while the effect at high frequencies (short run) is limited to a few countries.     

Services inflation dynamics and persistence puzzle in Brazil: a time-varying parameter approach

This article analyses services inflation dynamics in Brazil, focusing on the Services Inflation Persistence Puzzle, for monthly data from January 2004 to February 2016. We apply a time-varying parameter (TVP) approach, via a Kalman filter, to estimate hybrid Phillips curves and compare inflation inertia for tradable goods and services inflation. Aggregate Brazilian Extended Consumer Price Index inflation serves as a benchmark. To justify the TVP analysis, parameter instability and structural change tests are implemented, based on OLS and Generalized Method of Moments (GMM) frameworks. The main results are as follows: (i) the TVP approach is relevant due to observed instability in some parameters estimated; (ii) inflation expectation coefficients are higher than lagged inflation in all calculations, but inflation inertia is not negligible at all; (iii) services inflation persistence ranges from 27 to 36%, whereas tradable goods inflation persistence ranges from 36 to 47%, providing evidence of the Services Inflation Persistence Puzzle in Brazil; (iv) from 2009 onwards an increase in one percentage point in real wages raises monthly services inflation rate by 0.02 to 0.03 percentage point; (v) there is evidence that cost-push pressures, due to wage increases in the service sector, are more important to explain services inflation than demand pressures from early 2009 to mid-2014.     

Cohort,age and time effects in alcohol consumption by Italian households: a double-hurdle approach

This paper describes the life-cycle alcohol consumption patterns of Italian households by decomposing gender, cohort, age and time effects and estimates the importance of demographic characteristics using a double-hurdle model. The application is based on ISTAT households expenditure survey for the period 1997–2002 organized in cohorts. As expected, cohort and age effects are significant in both participation and consumptions. The significance of gender and geographic differences suggests important policy implications.      

The impact of housing market disturbances on the US financial system: a pre-crisis analysis

A common critique of the Federal Reserve over the past crisis is that it should have better anticipated the impact of the run-up in home mortgage debt and the subsequent housing market crash on the financial system. As a result, the Federal Reserve should have moved much more quickly to shore up financial markets. Our article tests the hypothesis that the impact of the housing market crash on the financial system could have been anticipated. Using a VAR model along with impulse response functions and variance decompositions, we examine the link between housing market mortgage debt shocks and the financial intermediaries’ credit market behaviour. We find important connections between key macroeconomic variables and the credit behaviour of these financial institutions. However, using the pre-crisis data, we find that housing market debt shocks fail to have an impact on the credit markets accessed by these firms. These results support the notion that the impact of this crisis on the financial system could not have been anticipated given the information available at the time.     

The relationship between wealth or income and time preference is empirical, not apodictic: a critique of Rothbard and Hoppe

There is no doubt that when income or wealth increases, impatience for present goods declines. When time preference for the present falls, interest rates decline as well. But is this phenomenon a necessary condition of human action as Rothbard and Hoppe contend? This is widely thought to be true when a man is on the very verge of death. There is an aphorism according to which “a drowning man will grasp even at the blade of a sword.” In this view, someone who is starving will not postpone the consumption of food for tomorrow that is necessary to keep him alive today. But we disagree. And what is the situation under more ordinary circumstances far removed from starvation? We argue in this paper that, contrary to Rothbard and Hoppe, under these conditions it is a reliable but only a broad empirical generalization that time preferences and interest rates are inversely related to wealth or income, it is not a matter of praxeology.     

The public and private provision of pure public goods and the distortionary effects of income taxation: a political economy approach

Abstract .  A pure public good is provided by the government and the voluntary contributions of two types of households. The government finances its contribution by means of income taxation. The latter has distortionary effects. A third type of household never makes contributions. We analyse the effects of changes in the income tax rate on (a) the provision of the public good, (b) the private contributions of the households, and (c) changes in the distribution of income and welfare between contributing and non-contributing households. We derive a simple and testable condition under which the lowering of the income tax entails a Pareto improvement.     

On the detection of extreme movements and persistent behaviour in Mediterranean stock markets: a wavelet-based approach

We combine the global Hurst exponent and Morlet wavelet multi-resolution analysis (MRA) to investigate the dynamic behaviour of six selected stock markets in the Mediterranean region. Specifically, we employ the resonance coefficients and their power spectra to identify potential extreme movements and long-term dependence in stock returns. Using weekly data for the period 2005 to 2010, our results reveal that the wavelet MRA is able to reconstruct the effects of major extreme shocks on stock returns of studied markets, such as the Asian financial crisis, the 9/11 terrorist attacks and the 2007–2009 financial crisis. Moreover, the wavelet-based global Hurst exponent indicates the presence of long-term dependencies in stock returns of all the considered markets, except for France where the anti-persistent behaviour is detected. Overall, our findings are useful to assess the stock market efficiency and provide new insights into stock market dynamics over different time scales.     

Regulatory and environmental effects on public transit efficiency: a mixed DEA-SFA approach

This paper assesses the impact of regulatory and environmental factors and statistical noise on the efficiency of public transit systems within a DEA-based framework. Using a panel of Italian companies, we implement a DEA-SFA mixed approach based on [H.O. Fried et al. (2002) Journal of Productivity Analysis, 17(1–2), 157–174] to decompose DEA inefficiency measures into three components: exogenous effects, managerial inefficiency and stochastic events. Besides providing evidence on the determinants of input-specific efficiency differentials across companies, the results point out that managerial skills play a minor role, and emphasize the relevance of regulatory policies aimed at replacing cost-plus subsidization with high-powered incentive contracts as well as improving environmental conditions of public transit networks.      

Notes and comments. Ricardo on income tax: a note

Despite the fact that Ricardo experienced Pitt's income taxpolicies, and that he regarded taxation as the most importantissue to which the principles of political economy should beapplied, he rarely referred to actual tax reforms. This paperindicates that Ricardo's system of economics cannot bring aboutany tax that is completely compatible with his main criteriafor taxation (distribution neutrality, price neutrality andminimum taxation) as well as certainty, convenience and thesecurity of property. This result may explain why Ricardo didnot say which type of taxation system the British governmentshould establish.     

Technological progress and market growth: An empirical study based on the quality-ladder approach

This paper develops an extended version of the quality-adder model by allowing for heterogeneous markets. Based on this model, it presents an empirical analysis of innovation-based growth at the market level using a technometric measurement concept. It can be shown that a growth-promoting effect due to technological progress in a particular single year is observed after between 2 and up to 7 years. This is true not only for highly innovative markets but also for those in which fewer R&D resources are invested.     

Measuring asymmetry and persistence in conditional volatility in real output: evidence from three East Asian tigers using a multivariate GARCH approach

We search for evidence of conditional volatility in the quarterly real Gross Domestic Product (GDP) growth rates of three East Asian tigers: Singapore, Hong Kong and Taiwan. The widely accepted Exponential Generalized Autoregressive Conditional Heteroscedasticity (EGARCH)-type model is used to capture the existence of asymmetric volatility and the potential structural break points in the volatility. We find evidence of asymmetry and persistence in the volatility of GDP growth rates. It is noted that the structural breakpoints of volatility correspond reasonably well to the historical economic and political events in these economies. Policy implications from our findings are discussed.
