Monetary Shocks, Inflation and the Asymmetric Adjustment of EU Output

Empirical studies have suggested that price rigidities ensure that real output responds asymmetrically to monetary shocks. Models advanced by Tsiddon and Ball and Mankiw argue that the degree of asymmetry to demand shocks is sensitive to inflation. This study tests whether this is the case for a sample of EU economies. Maximum likelihood estimation offers confirmation of output asymmetry in the cases of Germany and Italy but no such evidence in France and the UK.     

Asymmetric Adjustment Costs, Asymmetric Pricing and Employment: Evidence from the UK

This paper uses an asymmetric multivariate model to investigate asymmetries in employment and pricing behaviour by firms. This generalises the approach of Granger and Lee (1989) and also exploits the cross equation restrictions on the equations for prices and employment implied by a restricted cost function—the dual to a Cobb‐Douglas production function. Our results suggest that both prices and employment respond asymmetrically to shocks to costs and demand.     

Macroeconomic Structure and Oil Price Shocks at the Industrial Level

This paper analyses the role of the macroeconomic structure in the response of industrial output to an oil price shock in six OECD countries. The modelling of the macroeconomic structure is important in examining the effect of an oil price shock on the industry-level output, since the analysis of the transmission mechanisms helps us to better understand the response of industrial output to such a shock. Thus, cross-country differences found in the responses of industrial output to oil price shocks within the European Monetary Union can be partially explained by differences in the transmission mechanisms of such shocks.     

国际原油价格波动对中国宏观经济影响的重新考察

本文对国际原油价格波动对中国宏观经济的影响进行了重新考察。研究发现:国际原油价格通过影响采购经理人指数进而影响中国主要宏观经济变量,采购经理人指数的引入,完善了国际原油价格波动对中国宏观经济影响的时序传导机制,从而提高了实证结果的显著性。实证结果显示:国际原油价格上涨对中国消费者价格指数有正向影响,但这一结果并不显著;同时国际原油价格上涨并未改变中国经济增长的总体态势。VEC实证模型的估计结果表明:国际原油价格与中国宏观经济变量之间存在显著的协整关系,而且国际原油价格波动对中国宏观经济的影响存在滞后效应。     

非完全竞争市场假设在CGE模型中的引入及应用

通过对部门生产函数及相关参数、系数的改造,将非完全竞争市场条件引入CGE模型,并模拟在完全竞争与不完全竞争两个不同市场结构下国际油价上升对我国经济的影响.结果表明,当油品市场设定为不完全竞争时,面对国际油价上升的冲击,GDP下降的程度大于完全竞争的情况.因此随着油品市场逐渐开放,油品市场的产出增加,可以增强我国石油产业和总体经济应对国际油价上升冲击的能力,应继续推动我国石油产业市场自由化的进程.     

Macroeconomic Response to Oil and Food Price Shocks: A Structural VAR Approach to the Indian Economy

The study analyzed the dynamic impact of oil and food price shocks on the macroeconomy of India, using the monthly time series data from April 1994 to May 2016 in a structural vector autoregression (SVAR) framework. Being a net food exporter and net oil importer, the economy is found to face deleterious impacts of global oil and food price shocks on its macroeconomic performance. Output responds negatively to oil and food price hikes along with their volatility and positively to the fall in these prices. Inflation responds positively to all the three transformations of shocks with no signs of coming down, highlighting the price downward inflexibility in India. The study could not establish any evidence of negative demand shocks in face of oil and food price volatility. Central bank responds with a contractionary policy stance to negate the influences of external shocks. Forecast error variance decomposition points out the dominance of external shocks in influencing the domestic variables after their own shocks. Finally, the inflation downward rigidity is observed even in the long run.     

交易冲击下买卖报价的非对称调整模式研究

由于买卖报价共同分享股票有效价格,故两者是协整的时间序列,交易冲击后买卖报价在买卖价差的误差修正作用下逐渐回归到均衡水平。本文构建一个限制性VEC模型并利用中国股票市场数据进行实证研究。结果表明,交易冲击下买卖价差的修正作用显著,并通过买价的大幅增加和卖价的小幅降低来实现的。同时,交易冲击下的买卖报价是非对称调整的,主动性买使得买卖报价同时增加但买价增加得更多,而主动性卖导致买卖报价同时下调且买价调整幅度更大。另外,还发现买入往往比卖出包含更多的信息。     

Estimating the Markov-switching almost ideal demand systems: a Bayesian approach

Allias and Nichèle (Eur Rev Agric Econ, 34(4):517–538, 2007) proposed a Markov-switching almost ideal demand system (MS-AIDS) model by extending the idea of Hamilton (Econometrica, 57(2):357–384, 1989). In this paper, we propose a Bayesian estimation for MS-AIDS model and illustrate applicability of our proposed method. We then run two sets of simulation studies to confirm the validity of the proposed method. In the empirical study on the Japanese meat market, our Bayesian estimation improves the MSEs for all meat products over the ML estimation, while successfully capturing the regime shifts of meat demand coinciding with the timing of bovine spongiform encephalopathy cases in Japan and US.     

Smooth and Sticky Adjustment: A Comparative Analysis of the US and UK

This paper adopts the methodology of the microeconometric labor literature to analyze a common assertion from trade economists that reallocation within sectors is less costly than between sectors. Findings are compared across two countries (the UK and US) which have experienced very different recent aggregate unemployment experiences. Workers previously employed in "declining" sectors are more mobile than those employed in 'expanding' sectors in both countries, and individuals are more likely to switch sector the longer they are unemployed. A plausible explanation for this is that individuals initially attempt to find jobs that complement their general and specific skills in order to accrue the associated rewards, and move sector only as this prospect diminishes. This would seem to accord with the 'smooth adjustment hypothesis' which proposes that intraindustry adjustments are less costly than interindustry ones.     

Revisiting the interest rate–exchange rate nexus: a Markov-switching approach

In this paper the interest rate–exchange rate nexus and the effectiveness of an interest rate defense are investigated empirically. I present a reduced form evidence which characterizes the empirical relationship between interest rates and exchange rates. I use a Markov-switching specification of the nominal exchange rate with time-varying transition probabilities. Empirical evidence from six developing countries: Indonesia, South Korea, the Philippines, Thailand, Mexico, and Turkey indicates that raising nominal interest rates leads to a higher probability of switching to a crisis regime. Thus, the empirical results presented here may support the view that a high interest rate policy is unable to defend the exchange rate. Unlike other studies which consider linear models only, my findings are robust and consistent over different countries and crisis episodes (Asian 1997 crises, Mexico 1994 crisis, and Turkey 1994, 2001 crises). In order to explain the empirical findings, I construct a simple theoretical model by incorporating an interest rate rule in the model proposed by Jeanne and Rose (2002) [Jeanne, O., Rose, A.K., 2002. Noise trading and exchange rate regimes, Quarterly Journal of Economics. 117 (2) 537–569]. The model has multiple equilibria, and under plausible conditions, higher exchange rate volatility is associated with higher interest rates.     

Nonlinear effects of oil shocks on stock returns: a Markov-switching approach

Using Markov-switching models, we investigate whether oil price shocks have nonlinear effects on stock returns. Empirical evidence from a set of international stock indexes suggests that an increase in oil prices has a negative and significant impact on stock prices in one state of the economy, whereas this effect is significantly dampened in another state of the economy. Furthermore, it is shown that changes in oil prices or in oil price volatility do not lead to a higher probability of switching between regimes.     

国际原油价格波动对我国工业品出厂价格的影响——基于行业层面的实证分析

随着我国石油消费量和进口量的不断增长,国际原油价格的波动对我国经济的影响越来越大。基于38个行业的月度数据,本文详细分析了2003年1月-2009年2月国际原油价格波动对我国PPI指数的影响,研究发现:尽管为了降低国际油价对国内经济的冲击,政府仍对成品油定价体制实行部分调控,但国际原油价格的波动对我国PPI指数仍具有重要影响,尤其是生产资料价格以及石化行业等高耗能行业,而这主要与各行业的能源消费总量和能源利用效率有关。为此,我国应加快国内成品油定价体制改革,实施有效的产业政策,以促使各行业提高其能源利用效率,并最终有效地降低国际油价波动给我国经济带来的价格效应。     

UK Output Variability and Growth: Some Further Evidence

This paper re-examines the empirical evidence concerning the relationship between UK output variability and growth using GARCH-M models applied to post-war monthly industrial production data, estimated under quasi-maximum-likelihood with the consistent variance–covariance estimator of Bollerslev and Wooldridge (1992). In contrast to previous results suggesting a significant positive relationship between UK output variability and growth, we find no significant relationship. Rather than suggesting a connection between risk and return in the attitudes of investors, our findings may be interpreted as more supportive of macroeconomic models which dichotomize the determination of output growth and variability.     

Persistence of Shocks to Output in Austria and Theories of Economic Growth

The paper analyzes the degree of output persistence in GDP in order toempirically discriminate between the Solow growth model, the perfect competition endogenous growth model and the imperfect competition endogenous growth model for the case of Austria. Wefind that a shock in the growth rate of output induces a permanent and larger effect on the level of GDP. This leads us to refute the Solow growth model and the perfect competition model of endogenous growth.We may not reject the imperfect competition growth model.

中国产出冲击持久性影响的实证分析

产出冲击持久性影响的检验和估计是国外研究的热点.本文采集1952-2004年中国实际GDP数据,采用基于ARMA模型的脉冲反应函数的方法估计了中国产出冲击持久性影响的衡量指数.结果表明,整个样本期间产出冲击持久性影响的衡量指数为0.959,改革前和改革后这一指数分别为0.754和3.314,说明冲击对产出的影响具有持久性,但整个样本期间和改革前这种影响会被缩小,而改革后这种影响则会被放大.这些结果对宏观调控政策的操作具有一定意义.     

Forecasting UK international trade: A general equilibrium approach

Monthly retail unit sales of clothes washers and dryers in eastern Washington state were regressed on average employment during the current and preceding two months, the average advertised price of these appliances relative to the Consumer Price Index, the expected change in consumer stocks of such applicances for each year on the basis of a hypothetical rate of accumulation, and the unit volume of newspaper advertising in order to determine the viablity of alternative models for analysing and forecasting monthly sales in a localized retail market during the periods of growth, maturity, and decline in market demand.

Employment and advertising, the two most useful variables in the functions tested, were able to account for 70–75 per cent of the monthly sales variance for automatic washers and dryers. Employment elasticity coefficients, though not linearly related to income elasticity coefficients for these products, appear to be a useful measure of purchasing power for localized demand and forecasting functions. The average advertising elasticity for the products studied was 0.095, which was approximately equal to advertising expenditures as a ratio of the gross margin of furniture and house furnishings corporations and kitchen appliance departments of department stores for the period studied, in keeping with the Rasmussen hypothesis. Correction of the models for the presence of autocorrelation altered the explanatory power of some of the variables substantially and resulted in regression coefficients for some variables that were more nearly consistent with theoretical expectations.     

粮食产量与粮价波动关系的再研究

运用计量经济学的方法对粮食产量和粮食价格波动进行了实证研究。结果表明,粮食产量和粮食价格之间存在相互影响的关系,彼此之间对对方的变化都存在着滞后效应,而且价格变化对产量变化的影响要大于产量变化对价格变化的影响。从维护国家粮食安全的角度出发,为保证粮食持续稳定增长和价格的相对稳定,提出了相应的政策建议。     

论价格竞争与产业结构调整

近年来我国出现了接连不断的价格竞争,这不仅在企业界引起了阵阵恐慌与激烈的争论,也成为经济学界关注和讨论的重点。笔者认为,我国近年来出现的价格竞争有着深厚的产业结构背景,它是我国产业结构不合理的必然产物,是经济规律、价值规律在经济生活中的自发的强行的实现,只要能将价格竞争控制在一个合理的范围之内,它对我国的产业结构调整将会起到一定的积极作用。一、引起价格竞争的产业结构背景笔者在分析参与价格大战的产品与行业时,发现它们都有一个共同的特点———产业结构不合理,表现为:行业集中度低、规模效益低下、重复化建设严重、…     

The Role of Stocks and Shocks Concepts in the Debate Over Price Versus Quantity

Recent literature showed that the choice between a price or quantity control depends, in part, on the dynamic structure of cost uncertainty. Temporary shocks to abatement cost favors the use of a price control, while permanent shocks favor a quantity control. Unfortunately, the importance of this assumption to the optimal choice has not yet received wide attention among economists. We analyze the regulatory sproblem in an alternative setting and reproduce these results. Our contribution is the simplicity of the model and the accessibility of the results, which reinforce the critical role played by the assumed structure of uncertainty.
