通货膨胀国际间传导对我国影响的实证检验

本文运用时间序列分析方法,实证检验了欧盟和美国的价格冲击向我国传导的总体效应.实证结果表明,各国物价存在明显的协整关系,脉冲响应分析和方差分解的结论进一步刻画了外国通胀冲击的特征.协整变结构检验证实了近年来通货膨胀国际传导效应显著增强.本文还利用格兰杰因果检验,考察了通货膨胀的各条跨国传导路径,研究发现,消费品和原材料价格传导路径非常通畅,而通过国际储备影响货币供应量的传导渠道,以及总供给-总需求传导渠道不能得到实证支持.     

人民币汇率变动的物价传递效应:多结构变化协整回归分析

现有研究物价传递效应的文献以线性模型为主,甚少关注物价传递过程中可能存在的结构变化,本文在充分考虑我国转轨时期所面临的各种经济冲击的条件下,利用最新发展的多结构变化协整回归方法考察了1994年1月至2008年12月间人民币汇率变动的物价传递效应。研究结果表明,人民币汇率变动的物价传递效应分别在1998年8月、2002年10月、2005年8月及2007年7月发生了四次结构变化,传递效应虽总体趋减,但2007年7月后出现了反复,且符号也发生了改变。在上述结论基础上,本文提出了相关政策建议。     

Exchange rate pass-through and relative prices: An industry-level empirical investigation

In this paper we explore the extent of exchange rate pass-through for the USA, UK and Japan using a post-Bretton Woods industry-level dataset. We investigate how different channels of exchange rate pass-through affect domestic and import prices. Our analysis is suggestive of two channels of transmission and we find considerable variation in the extent of pass-through across industries and countries.     

我国出口汇率传递的非对称性:来自中日贸易的证据

文章扩展了Yang（2007）的厂商定价模型，对汇率传递非对称性、特点和成立条件进行理论分析，发现对称传递需要满足严格的条件，而现实中更常见的是非对称汇率传递。在一定条件下，商品需求弹性越大，越可能呈现出口国货币贬值传递率高而升值传递率低的特点。利用2000年1月至2011年12月我国出口日本的966种商品价格数据，发现汇率波动向价格传递具有非对称性：（1）人民币升值时，日元价格上涨较少；而贬值时，价格下降较多。我国出口商品的需求弹性较大，在日本市场上面对的是一个强竞争结构。（2）若月度升值超过一定幅度（测算约为2.43%），传递率又会有所上升，说明尽管日元价格易跌难涨，但在升值导致成本上涨较多、明显挤压利润时，厂商不得不适当提高日元售价。采用2000年至2018年9月日本从中国进口单位价值指数进行稳健性检验，得出类似结论。现阶段稳定的人民币名义汇率对我国出口企业是更为有利的。     

The effects of exchange rate pass-through and cost channel on price level: The case of fragile five countries

ABSTRACT

In this study, we investigated whether the exchange rate and the interest rate had an effect on the inflation rate in the fragile five countries between the years of 1996Q4 and 2015Q4. In this context, a model was created to estimate the effect of interest rate and exchange rate on the inflation rate. The methods used in the study take into account cross-section dependence and heterogeneity. As a result of the analysis, it was determined that there was an exchange-rate and interest-rate pass-through effect in the fragile five countries. Moreover, it was found out that the cost channel and price puzzle were effective in Indonesia and South Africa but were not effective in Turkey, Brasil and India.     

Commodity price pass-through in the US airline industry and the hidden perks of consolidation

How do changing jet fuel prices impact airline revenues? As expenses for jet fuel are one of the most relevant cost factors for airlines, their economic success largely depends on the ability to match changes on the cost side with an adaption on the revenue side. While previous studies primarily focused on the impact of fuel price changes to consumer prices, this paper empirically examines the ability of US airlines to pass-through lagged jet fuel prices to scaled operating revenues from an airline driven perspective. Our results suggest that the extent to which an exogenous increase in fuel prices can be passed on to revenues will deviate according to the competitive situation faced by an airline. Based on these findings our research should also be of interest for European policy makers who are discussing actions to exogenously increase jet fuel prices due to environmental reasons.     

Interest rate pass-through in Morocco: Evidence from bank-level survey data

We investigate the relationship between banks’ marginal cost and retail lending rates in Morocco. The data covers the rates of new business loans for four market segments broken down by institutional sector between 2006Q2 and 2016Q4. We examine the pass-through mechanism using recently developed heterogeneous panel cointegration framework. Our findings suggest that there is a high degree of pass-through heterogeneity over bank products. The weak adjustment for short-term credit facilities and consumption loans can be explained by credit risk compensation allowing banks to reduce their exposition to systemic risks. Corporate loans are priced more competitive than household and individual entrepreneur products, suggesting that negotiation power or the competition from the borrower side matters. Overall, our results indicate that banking market contestability has improved during the last decade.     

Understanding changes in exchange rate pass-through

Recent research suggests that there has been a decline in the extent to which firms “pass-through” changes in exchange rates to prices. This paper provides further evidence in support of this claim. Additionally, it proposes an explanation for this phenomenon. The paper then presents empirical evidence of a structural break during the 1990s in the relationship between the real exchange rate and CPI inflation for a set of fourteen OECD countries. It is suggested that the recent reduction in the real exchange rate pass-through can in part be attributed to the low inflationary environment of the 1990s.     

Who bears the cost of a change in the exchange rate? Pass-through accounting for the case of beer

Nominal exchange rates are remarkably volatile. They ordinarily appear disconnected from the fundamentals of the economies whose currencies they price. These facts make up a classic puzzle about the international economy. If prices do not respond fully to changes in the nominal exchange rate, who bears the cost of such large and unpredictable changes: foreign firms, domestic firms, or domestic consumers? This study presents a new analysis of the sources of incomplete pass-through and then uses this analysis to re-examine its implications for social welfare. I develop and estimate a structural model that analyzes the sources of local-currency price stability for a particular industry. The model enables counterfactual simulations that quantify the relative importance of firms' local-cost components and markup adjustments in the incomplete transmission of exchange-rate shocks to prices and the effect of the exchange-rate shock on domestic and foreign firms' profits and on consumer surplus. The model is applied to a panel dataset of one industry with retail and wholesale prices for UPC-level products. I find that markup adjustments by manufacturers and the retailer explain roughly half of the incomplete transmission and local-cost components account for the other half. Foreign manufacturers generally bear a greater cost (or reap a greater benefit) following an exchange-rate-induced marginal-cost shock than do domestic consumers, domestic manufacturers, or the domestic retailer.     

Vehicle currency use in international trade

We explore the major driving forces for currency invoicing in international trade with a simple model and a novel dataset covering 24 countries. We contrasts a “coalescing” effect, where exporters minimize the movements of their prices relative to their competitors', with incentives to hedge macroeconomic volatility and transaction costs. The key determinants of invoice currency choice are industry features and country size, with some role for foreign-exchange bid-ask spreads. The coalescing effect also goes a long way to explaining the well-known dominance of the dollar. Trade flows to the United States are predominantly invoiced in dollar, as foreign exporters face competition with U.S. firms. The use of the dollar in trade flows that do not involve the United States reflects trade in homogeneous products where firms need to keep their price in line with their competitors'.
