The impact of oil price movements on bank non-performing loans: Global evidence from oil-exporting countries

It is generally believed that economic and financial performance in oil-rich countries are interlinked to oil price movements. On this assumption, we consider whether oil prices shocks have any impact on bank non-performing loans (NPLs), and if so, whether the effect is homogenous across banks. This paper addresses these questions by applying a dynamic GMM model on data from 2310 commercial banks in 30 oil-exporting countries over the period 2000–2014. Three main results emerge. First, changes in oil prices do have a significant impact on bank NPLs: A rise (fall) in oil prices is associated with a decrease (increase) in NPLs. Second, oil prices shocks have asymmetric effects on bank problem loans, with negative oil price movements generally have a greater impact than positive oil price movements. Third, the unfavourable impact of adverse oil prices shocks on the quality of bank loans tends to be more pronounced in large banks. Overall, these robust results favour the adaptation of appropriate macroprudential policies and diversification of the economy, in order to mitigate the adverse impact of oil prices shocks.     

Asymmetric effects of oil price changes on the balance of trade: Evidence from selected African countries

The main new contribution of this study was to delve into the asymmetric impacts of changes in oil prices on the trade balance in the framework of six major African economies. To tackle this topic carefully, we employ three measures of external balances—oil, non‐oil and total trade balances, and assess the asymmetric response of the external balances of those six economies to oil price changes in the short and long run. Like most previous studies, we first assume the impacts of oil price fluctuations to be symmetric and employ the linear autoregressive distributed lag (ARDL) method to explore the topic. We then separate oil price hikes from oil price plunges and implement the non‐linear ARDL method to reveal that the price of crude oil has a vital role to play in the trade balances for those six African economies. Further, there is evidence of significant asymmetric impacts of oil prices typically on the oil trade balance of Africa's top oil producing countries. For the non‐oil and total trade balances, in contrast, there is little evidence of the asymmetry of oil price changes.     

国际油价与人民币汇率的非对称溢出效应研究--基于VEC-BEKK-GARCH模型

石油作为重要的战略能源,其价格波动对全球经济的运行和发展会产生极大的影响。为测算国际油价与人民币汇率的均衡关系及非对称溢出效应,选取2008年1月~2019年7月的每日数据,在平稳性检验的基础上,综合运用协整检验和脉冲响应函数等方式,对二者的均值溢出效应进行测量;在VECBEKK-GARCH模型的支撑下,对其非对称波动溢出效应水平进行测算。研究结果表明:国际油价与人民币汇率的协整关系和均值溢出效应处于长期均衡状态;二者的非对称波动溢出效应是双向的,国际油价会随人民币汇率的变化呈现出时变性和持续性特征,而国际油价变动具备持续性特征时,人民币汇率随之产生变化。这种非对称波动溢出效应表明,无论国际油价如何变化,对人民币汇率的冲击都是非对称的。     

The effect of oil price shocks on asset markets: Evidence from oil inventory news

We quantify the reaction of U.S. equity, bond futures, and exchange rate returns to oil price shocks driven by oil inventory news. Across most sectors, equity prices decrease in response to higher oil prices before the 2007/2008 crisis but increase after it. Positive oil price shocks cause a depreciation of the U.S. dollar against a broad range of currencies but have only a modest effect on bond futures returns. The evidence suggests that changes in risk premia help to explain the time-varying effect of oil price shocks on U.S. equity returns.     

The impact of monetary policy on oil price persistence: An application of the smooth regime-switching model

This paper employs the smooth transition autoregressive model to evaluate the persistence of oil price changes, and chooses monetary policy variables as transition variables of the model to assess their roles in the persistence effects. The empirical results show that oil price changes displayed asymmetric adjustments within different regimes and were more sensitive to the movement of interest rates than inflation rate. In addition, high inflation rate would give rise to low oil price persistence, and expansionary monetary policy would bring about higher oil price persistence. Moreover, when the short- and long-term interest rates were over their threshold values, the persistence effects of oil price changes were opposite. In the present relatively low US interest rates, adopting either an inflation-targeting policy or/and a debt-financing policy to stimulate economic growth, the timing is appropriate and the effect will be positive and expected because of low persistence of oil price changes.     

Modeling the employment–oil price nexus: A non-linear cointegration analysis for the U.S. market

ABSTRACT

Theoretically, fluctuations in oil prices are expected to affect production costs and may force businesses to delay their investment decisions, triggering pressures on employment. Following these theoretical notions, this paper investigates the asymmetric impact of oil prices on employment (measured as total employment, male employment, and female employment), in a nonlinear cointegration structure for the U.S. market. In doing so, this paper adopts the nonlinear autoregressive distributed lags (NARDL) model to shed light on such asymmetric association, as the NARDL model recently emerged as a new direction in examining nonlinear cointegration and asymmetry. The empirical findings document a long-run asymmetric effect in case of total employment and male employment only. Furthermore, the short-run asymmetric effect was detected for all three employment categories. As a final point, the Granger Causality test documents a unidirectional causality running from oil price decrease to both total employment and male employment.     

Oil price shocks in a portfolio-balance model

In the 1970s oil price increases were often associated with downward pressure on the foreign exchange value of the dollar. In order to identify the factors generating this association, we examine an oil price shock in a portfolio-balance framework where a wealth transfer is generated by altered current account positions. We show that the exchange-rate impact of higher oil prices depends importantly on the asset prefernces of both oil importers and oil exporters, as well as exchange rate expectations, which are influenced by countries' abilities to adjust to higher oil prices.     

Crude oil prices and the balance of trade: Asymmetric evidence from selected OPEC member countries

The contribution of this article is to assess whether the effects of crude oil price fluctuations on the trade balance are symmetric or asymmetric in the context of an individual oil-exporting country, specifically four OPEC member countries – Iran, Nigeria, Saudi Arabia, and Venezuela. To examine this subject thoroughly, we use three different measures of trade balances such as oil trade balance, non-oil trade balance, and total trade balance, and examine whether oil prices are asymmetrically passed on to the trade balances for those OPEC countries in the long- and short-run. After implementation of the nonlinear autoregressive distributed lag (ARDL) model, we find that changes in oil prices indeed have asymmetric effects on the oil trade balance for all four OPEC countries in the long-run, though not in the short-run. In the case of the non-oil and total trade balance, however, the asymmetry of oil price changes is not detected in both the long- and short-run.     

Opposing effects of sociodemographic variables on price knowledge

This paper examines the impact of sociodemographic variables (age, income, and occupation) on price memory. We argue that these variables may exert opposing effects on ability and motivation to process price information, explaining why prior literature has found inconclusive effects of sociodemographics on price knowledge. To tease apart the influence of ability and motivation on price processing, we report the results of a field experiment among 683 shoppers manipulating an ability-related variable (familiar or unfamiliar currency) and a motivation-related variable (normal or 50 % higher prices), and we measure willingness and accuracy to recall and recognize prices as a function of consumers’ age, income, and occupation. We find that consumers with the sociodemographic drivers of lower ability but higher motivation (older, less affluent, and lower occupational categories) have worse price memory, especially when the prices are expressed in an unfamiliar currency (the ability-related manipulation).     

Recent Evidence on the Oil Price Shocks on Gulf Cooperation Council Stock Markets

The recent plunge in the price of oil affected many countries, especially major oil producers and exporters, such as the Gulf Cooperation Council (GCC), which accounts for half of the global oil reserves. This paper examines the impact of oil price changes on GCC stock markets, including Bahrain, Kuwait, Oman, Qatar, Kingdom of Saudi Arabia, and United Arab Emirates over a 10-year period, 2005–2015. We examine the direction of influence and influence absorption through Granger causality and impulse response function. The results are important for portfolio management at the international level, and provide insights for government and regulatory authorities in times of oil price change. Additionally, the evidence suggests the need for more economic diversification at the country level in the GCC region to mitigate high volatility in the event of oil shocks.     

The impact of crude oil inventory announcements on prices: Evidence from derivatives markets

This study examines the impact of weekly crude oil storage announcements on oil futures and options prices. We document evidence of a strong announcement day effect on both markets, and find prices to move in anticipation of the inventory surprise. Futures returns significantly decrease with positive surprises and increase with negative surprises. There is no evidence of an asymmetric impact on futures prices. Near‐the‐money options exhibit the greatest price sensitivity, and the magnitude of the price response of both futures and options declines with maturity. The results remain robust even after controlling for various macroeconomic and other storage‐related news variables.     

Foreign investment,regulation and price volatility in South-east Asian stock markets

This paper examines the extent to which changes in the openness of three South-east Asian Stock Markets to foreign investors impact on the volatility of prices in those markets. Regulatory authorities have been cautious about the opening up of markets to foreign investors, fearing that increased liberalisation may lead to increased price volatility, which, in turn, may have a detrimental effect on the operation of the market and the wider economy. Using an asymmetric GARCH model, it is shown that while greater liberalisation has changed the nature of price volatility in the markets, there has not been a destabilising impact. Rather, asymmetric responses of volatility to news have reduced post-liberalisation, suggesting that informed traders are playing a greater role in the markets, with the impact of noise traders being reduced.     

The impact of external reference price on consumer price expectations

Comparative pricing practices are frequently used where actual product prices are accompanied by higher external reference prices. All types of stores, regular-price department stores as well as discount stores, use comparative price claims to frame price deals as attractive [Marketing Science 4 (1985) 199]. In this paper, a quadratic model is specified for the impact of external reference price (ERP) on consumer price expectations. Based on the research on communication discrepancy and advertising claim discrepancy, which in turn draw on assimilation-contrast, attribution, and prospect theories, we hypothesize a quadratic effect of external reference prices on consumer price expectations. An interactive, computer-controlled experiment using multiple levels of ERP is used to estimate the proposed model. As hypothesized, support for an inverted U-shape relationship is found between consumers’ updated price expectations and the difference between ERP and initial price expectations. That is, as the difference between ERP and subjects’ initial price expectations increases, subjects’ updated price expectations increase to a point and then start to decrease. We find that the fit of the quadratic model specification for the effect of external reference price on price expectations is noticeably superior to that of linear, logarithmic, square root, and S-shaped specifications. Finally, we provide implications of our results for both retail managers and for regulatory authorities alike.     

Examining futures price changes and volatility on the trading day after a limit‐lock day

This paper examines the effect that price limits have on futures prices by testing what happens to price changes and volatility on the trading day following a limit‐lock day. The results show evidence that prices continue to rise on average the day after an up‐limit day. In addition, limits appear to influence price volatility for some but not all of the futures contracts. However, since the findings vary across the different commodity futures contracts, it is likely that limits do not directly impact price volatility. © 2000 John Wiley & Sons, Inc.

Time‐varying market price of risk in the crude oil futures market

In this study, a three‐factor model of crude oil prices is estimated, which incorporates a time‐varying market price of risk. The model is able to accurately capture the term structure of futures prices with evidence suggesting that risk premiums in the crude oil market are time‐varying. Using the cross‐section of futures prices, we estimate a time‐series of the market price of risk in the crude oil market implied by the model. We find that the risk premiums in the crude oil market are driven by the same risk factors as equity and bond markets. © 2010 Wiley Periodicals, Inc. Jrl Fut Mark 31:779–807, 2011     

Franchising versus corporate ownership: The effect on price dispersion

This paper uses data on the prices charged at fast-food restaurants in the metropolitan Pittsburgh and Detroit areas to assess the effect of franchising on price dispersion within chains in fairly narrowly defined geographical areas. A review of reasons why firms may face more price dispersion under franchising guides the empirical analyses. Results indicate that 1) franchisors do not aim for fully uniform prices even on the corporate side of their chains, 2) the degree of price dispersion is highest for firms with both franchised and company-owned units, as predicted by models implying a systematic price differential between units operated under these different contracting mechanisms, and 3) price dispersion for fully franchised chains is greater than for fully corporate chains. These last two results, combined with evidence from court cases that franchisors sometimes try to control franchisee prices directly, suggest that franchisors indeed lose some amount of control over prices charged to customers when they use franchising as opposed to corporate ownership. Finally, I find a positive effect of the royalty rate on price dispersion. This suggests that double marginalization is behind at least some of the higher prices found in franchised units in the existing literature.     

Distortion of price discount perceptions through the left-digit effect

Through two experiments, we examined the consumers’ process of comparison of regular and sale price information in advertisements. This is an extension of studies of the left-digit effect with different price levels and multiple digits conducted using Taiwanese data. First, we find that in a comparison of regular and sale prices, specifically three-digit integers with different leftmost digits, consumers perceive the price discount to be larger when the left digit is small (e.g., 1 or 4) than when it is large (e.g., 7). The lower the two prices being compared, the more likely it is that the left-digit effect will exist. Second, the perceived discount is likely to diminish when the number of digits is increased to produce a four-digit integer. In other words, the number of digits can affect perceptions of the numerical difference when comparing two prices. Thus, the effect of a left-digit change to produce a nine-ending price would be weaker for higher-priced products. The findings indicate the existence of a novel boundary to the left-digit effect.     

Large trades and intraday futures price behavior

This study examines the effects of large trades executed by outside customer on the prices of futures contracts traded on the Chicago Mercantile Exchange. We find that, on average, large buyer-initiated trades have a larger permanent price impact (information effect) than large seller-initiated trades, whereas the opposite is found for the temporary price impact (liquidity effects) of large trades. These results are consistent with previous findings for block and institutional trades in equity markets. However, we also find that the information effects of large sells are larger than large buys in bearish markets, whereas the results are the reverse in bullish markets. The liquidity price effects of buys are larger than the liquidity price effects of sells in bearish markets whereas the reverse results hold in bullish markets. Our results are consistent with the hypothesis that the current economic condition is a key determinant of asymmetric price effects between large buys and large sells. © 2008 Wiley Periodicals, Inc.

Using daily store-level data to understand price promotion effects in a semiparametric regression model

Though it has been widely reported in the marketing literature that temporary price discounts generate substantial short-term sales increase, the shape of the deal effect curve constitutes a key research topic, for which there are still limited empirical results. To address this issue, a semiparametric regression approach is used to model the complex nature of this phenomenon. Our model is developed at the brand level using daily store-level scanner-data, which allows the study of several nonreported promotional effects, such as the influence of the day of the week both in promotional and nonpromotional periods. The results show that the weekend is the most effective in increasing promotional sales and that asymmetric and neighborhood effects hold. However, 9-ending promotional prices are not impactful.
