Asymmetric spot‐futures prices adjustments in Quebec grain markets

AbstractAsymmetric price transmission has been the subject of many studies in agricultural economics, but few has been said on Quebec grain market. This study uses threshold cointegration models to examine the dynamic relationship between Quebec spot and futures prices. Estimation results with daily, weekly, and monthly data from September 1994 to May 2022 are three‐fold. First, the main point to keep from cointegration tests is that futures prices and Quebec local grain prices are integrated but estimations with daily data are consistent to highlight a nonlinear long‐run relationship. Second, results indicate overall positive asymmetric for daily and weekly prices transmissions from futures to spot market. Third, the positive asymmetric prices transmissions shed light on the oligopoly structure of Quebec grain market and inefficiencies in the pricing mechanism which favor local grain sellers. Results with different data frequencies show that aggregated monthly prices data compared to more disaggregated data such as daily and weekly prices may lead to different results. Results imply that policymakers and market stakeholders could facilitate increased grain market competition. Grain users like Quebec hog producers need to better understand additional tools for their management of price risk like futures market and real time prices movement monitoring.

Price linkages in major EU virgin olive oil markets

This study examines the price relationships between the three major EU olive oil markets; Spain, Italy and Greece. The empirical analysis utilises a series of linear and non-linear econometric techniques to explore long and short run relations examining market integration as well as the pattern of price transmission. The study utilises monthly wholesale data for virgin olive oil for the three countries, covering the period January 2000 to April 2022. Results from the Diks and Panchenko nonlinear causality test suggest Spain to be the central market and stable long-run relations are revealed between the examined price pairs through the non-linear Momentum Threshold Cointegration model, with the strongest relation being identified between Italy and Greece. Regarding the pattern of price transmission, it is found to be asymmetric for the pairs Spain-Greece and Spain-Italy, whereas for price pair Italy-Greece symmetry is confirmed, and the Law of One Price holds in its strong version. This suggests that while the markets are integrated, the EU olive oil market is characterised by inefficiencies indicating the need for further reforms.

Revisiting the relationship between Oil Price and Food Prices in the US: Evidence from Threshold Cointegration with Asymmetric Adjustment

The main objective of this paper is to investigate the interaction between oil and food prices using threshold cointegration analysis. The study uses monthly data from January 1997 to September 2020. Empirical results reveal evidence of asymmetry in the adjustment process toward equilibrium. Uni-directional causality is detected between the variables, with oil prices causing changes in food prices. Additionally, oil prices are found to be cointegrated with food prices, suggesting the presence of an asymmetric adjustment mechanism. Specifically, the speed of adjustment to equilibrium varies depending on the sign of the last equilibrium error. The study recommends that policymakers should consider adopting measures that promote energy diversification, sustainable agricultural practices, and price stabilization mechanisms to mitigate the impact of oil price fluctuations on food prices and to enhance overall economic stability.

Unravelling the nexus between energy prices and exchange rate in Malaysia: Fresh insights from a non-linear perspective using threshold cointegration analysis

This paper proposes a nonlinear threshold cointegration framework to study how energy prices affect Malaysia's nominal exchange rate, considering the money supply, income, and interest rate. The study employs a threshold cointegration approach utilizing threshold autoregressive and momentum threshold autoregressive models. The momentum threshold vector error correction model determines the short-run adjustment of exchange rate deviation from the long-run equilibrium level. The findings reveal that the nonlinear adjustment process to capture the short-run deviation in the long-run equilibrium path is primarily influenced by energy prices, money supply, and interest rates. These results highlight the importance of considering the impact of energy prices on exchange rate policies when formulating and implementing economic policies in Malaysia. The findings can also be valuable for decision-makers to comprehend the future dynamics of exchange rates and make well-informed decisions.

The Saving-investment Relationship Revisited: New Evidence from Regime-switching Cointegration Approach

This paper exploits the regime-switching threshold cointegration approach to elicit the dynamics in the saving-investment relationship and capital mobility in India. Empirical results offer key insights into the threshold cointegration between the saving and investment rates. We find that the adjustment in investment rate in the upper regime is faster than in the lower regime, indicating the higher mobility of capital in the upper regime. Further, results reveal the absence of firm evidence of long-run vs. short-run asymmetries between saving and investment rates. However, results suggest that cumulative positive and negative sums of saving rates affect investment rates. We have made adjustments to cyclical and trend patterns in our data using Hamilton's (2018) filter and have produced robust results with regard to asymmetric cointegration. The posterior estimation results suggest that a downward trend in the saving rates substantially impacts the investment rates, and widening the gap between saving and investment rates facilitates huge mobility of international capital in the long run.

Threshold cointegration and asymmetries between dividends and earnings news

Cho et al. (2023) provided evidence of an asymmetric relationship between dividends and earnings using postwar US data. This note extends the analysis to threshold cointegration and demonstrates that dividends respond differently to positive and negative earnings shocks and that the response depends critically on which region the system lies when a shock occurs.

Can U.S. strategic petroleum reserves calm a tight market exacerbated by the Russia–Ukraine conflict?

Recent changes in global petroleum markets have driven the debate regarding the use of strategic petroleum reserves (SPRs) as a price management tool during periods marked by extreme price volatility. We examine the price management role of the U.S. SPR under typical market conditions and in extreme emergencies. Furthermore, we discuss the White House's hypotheses that (a) boosted Organization of the Petroleum Exporting Countries' (OPEC) production and releases from the U.S. SPR result in a negative pressure on U.S. gasoline inflation, and (b) crude oil releases from the U.S. SPR helps balance the global oil market. The threshold cointegration results indicate that U.S. SPR releases impact neither OPEC production nor imported input prices. We apply a hybrid open-economy Phillips curve to model gasoline inflation, accounting for backward- and forward-looking price settings, domestic and global slackness, and energy security. We distinguish between normal-, super-, and hyper-backwardation and -contango oil markets using threshold cointegration and regression techniques. Our results demonstrate that SPR releases and OPEC output increases generally decrease inflation, with a crucial exception being the hyper-backwardation market, as seen in 2021–2022. This period was characterized by severely constrained global supply buffers, including OPEC's spare capacity, exacerbated by the Russia–Ukraine conflict. For this period, we conclude that (1) the impact of OPEC production changes on gasoline inflation would be negligible, (2) excess domestic demand relative to domestic supply raises concerns about domestic energy security, and (3) the unprecedentedly large SPR drawdowns are likely to have caused the market to panic and contributed to gasoline price increases, contrary to arguments suggesting that the 2022 releases eased domestic gasoline prices. We conclude that the SPR is an ineffective price control mechanism during crises and may not have the strategic value previously thought in an extremely tight oil market.

Threshold Cointegration and Price Transmission in Commodity Marketsof India

The purpose of this research work is to examine the relationships and price dynamics between agricultural commodities in India, i.e.maize, wheat, barley and soybean. Our approach is to study the long-term relationship using the method of modelling the price transmission for both linear and threshold autoregressive (AR) models and vector error correction (VEC) models. Results revealed that all the price series are well integrated, and threshold error correction models prove that all price series move to restore the long-run relationship, whereas commodity stock prices respond slightly faster than market prices in the short-run. Conclusions from this study show that understanding the price transmission flow and its impact on pricing might help in making better trading strategies. It also regulates the public policy implications of the active participation of farmers in national-level commodity exchanges.

HOW DOES U.S. REDUCE THE FOOD WASTE BY PREDICTING FOOD AWAY FROM HOME AND FOOD AT HOME?

This study examines the relationship among consumer confidence, food away from home (FAFH) and food at home (FAH) in the U.S. to figure out the high potential food sector for reducing food waste. Specifically, this paper uses the monthly data from January 2010 to December 2020 and the threshold vector error correction model (TVECM) for the analysis. Our test results of Johansen cointegration and threshold cointegration show that pairs of consumer confidence–FAFH and consumer confidence–FAH have a nonlinear long-run relationship. According to TVECM results, consumer confidence has a positive long-run Granger causation on FAFH approximately 93% (regimes 2 and 3), and on FAH over 5.4% (regime 3). About 7% of periods (regime 1) not included for a long-run Granger causation of consumer confidence on FAFH, and 5.4% period on FAH pertain to the COVID-19 period. Therefore, we conclude that a positive long-run Granger causation of consumer confidence on food consumption in the U.S. exists only in the FAFH. Based on our results, the policy implication is that the U.S. should focus on the FAFH to reduce food waste by predicting food demand to manage food stock.

Does Twin Deficit Hypothesis Exist in India? A Structural Break Co-integration Analysis

The primary focus of this study is to examine the long-term and short-term impact of fiscal deficit (FD) on the current account deficit (CAD) in India over the period of 1980 to 2021 in the presence of inflation and exchange rate. For the estimation of data series, the study employed autoregressive distributed lag (ARDL) co-integration test and Gregory Hansen (GH) co-integration test with endogenous structural break. The empirical results from ARDL bounds tests fail to provide a long-run relationship for the variables. The threshold co-integration test (GH) estimation suggests a strong evidence of a co-integration relationship for the variables and the break year is found in 2005. Thus, the findings validate the twin deficit hypothesis in the long-run as the FD has a positive significant effect on a CAD in India. Similarly, the long-run estimates of inflation have a positive significant effect on the CAD. It implies that an increase in rate of inflation distorts the CAD in the long-run. Consequently, the government of India should control the price hike and make macroeconomic situations favourable for domestic tradable sectors. The results from the Granger causality technique show bidirectional causality between FD and CAD implies the twin deficit in India. Based on the empirical findings, it may be argued that the Central Bank of India should try to reduce the prolonged CADs and retain stability in the domestic currency.

Revisiting the twin deficits hypothesis in the United States: Further evidence based on system-equation ADL test for threshold cointegration

We revisit the twin deficits hypothesis (budget and trade deficits) for the United States during 1791–2019, using the system-equation ADL test for threshold cointegration proposed by Li (2017). This model can demonstrate the existence of both asymmetric adjustment and asymmetric role in the relationship between trade and budget deficits. Our empirical evidence suggests a nonlinear long-run relationship between the two variables, thus finding the presence of the twin deficits hypothesis. Further, we find time–varying cointegration between the two, and an asymmetric adjustment process. Budget deficits play a vital adjustment role at low regimes (when error-correction terms are below the threshold of 1.11), and trade deficits play an important adjustment role at higher regimes (when error-correction terms are above the threshold of 1.11).

Impact of Exchange Rate on Trade Balance of India: Evidence from Threshold Cointegration with Asymmetric Error Correction Approach

In this research, we investigate the dynamic relationship between the trade balance and exchange rate in the case of India using threshold cointegration and an asymmetric error-correction model. Empirical results validate that the long-run dynamic relationship between the trade balance and exchange rates is asymmetric. In the short run, the trade balance responds only due to positive deviations in the exchange rate. In contrast, in the exchange rate model, the exchange rate reacts only due to negative deviations in the trade balance. In addition, the results exhibit that the adjustment following variation in the exchange rate seems higher than the adjustment in the trade balance in the short run. Besides, the results indicate that the speed of adjustment due to the positive and negative shocks differs in the trade balance and the exchange rate models. Further, the uni- directional Granger causality result suggests that the trade balance substantially affects the exchange rate. However, the Granger causality effect of the exchange rate on the trade balance seems minimal. Finally, our results validate the impact of momentum equilibrium adjustment path asymmetric effects between the trade balance and exchange rate, indicating that the adjustment path is asymmetric in the long run. Therefore, policy planners in India should consider the asymmetric adjustment between these two drivers to overcome trade balance discrepancies in the short and long run.

When cointegration is interrupted: Price transmission analysis in the Italian dairy‐feed industry

AbstractWe analyze price transmission dynamics in the under‐investigated feed supply chain, applying a special case of the Threshold Vector Error Correction model where the cointegrating relationship is interrupted. Weekly Italian dairy feed and corn prices are used, finding evidence of asymmetric price transmission when the feed industry's margins are squeezed and highly volatile. The proposed Interrupted Threshold Cointegration model represents a valid complement to existing threshold and regime‐switching techniques, allowing for the application of an agile nonstructural error correction model when standard cointegration tests fail to detect any long‐run relationship between price series.

Food price and Inflation Adjustments in Nigeria: Evidence from Threshold Cointegration

This paper investigates two stages of transmission through which inflation stabilization policy affects headline inflation by estimating a threshold cointegration model. The paper finds that asymmetric monetary shocks passing-through food prices exerts inflationary pressure on consumer prices, and is characterized by deep asymmetric movement, large degree of stickiness in adjusting downward, while exhibiting upward momentum in correcting food price fall. In addition, asymmetries were found in consumer price adjustment as food price shock transmits substantial inflationary pressure to consumer prices, while disinflationary effect originating from a fall in food price is inconsequential. The coefficients of adjustment were found to be robust in the sub-sample. This paper concludes that an unconventional monetary policy intervention that aims at stabilizing headline inflation by means of stimulating food supply could unavoidably inflate food prices more than it could deflate it especially if the elasticity of domestic food output to money supply growth is less compared to response of food price to money supply. Hence, caution must be taken on the size differential of output response to the net rise in money supply and price adjustment to the expansion in money supply.

Public Debt and Economic Growth in Nigeria: Evidence from Threshold Cointegration

The aim of most government when accumulating public debt is to enhance an improved economy. However, economic performance has been abysmally poor in Nigeria despite its high debt profile. Few studies have considered the nonlinear relationship between public debt and economic performance in Nigeria using the threshold cointegration technique. Therefore, this study examined the threshold effect of public debt on economic growth using time series data from 1985 to 2020. Findings revealed asymmetric cointegration between public debt and economic growth (F [p1 = p2 = 0], = 13.118, p ˂ 0.05). The results of the asymmetric error correction model found that public investment had a positive and significant relationship with economic growth (β = 0.675, t = 3.542, p ˂ 0.05) while trade openness had a negative and significant relationship with economic growth (β = -0.226, t = -3.617, p ˂ 0.05). The study concluded that there is a threshold cointegrating relationship between public debt and economic growth in Nigeria. Therefore, the study recommends that the Nigerian government should efficiently utilize funds borrowed domestically and contract less of external debt in order to maintain a sustainable economic growth.

Interest Rate Pass-through in Nigeria: An Asymmetric Cointegration Approach

This paper empirically examines the pass-through of the Central Bank of Nigeria policy rate to commercial banks’ retail rates. The study covers the pre-liberalization (1962M01–1987M07) and post-liberalization (1987M08–2020M09) periods, and emplys asymmetric cointegration and error-correction modelling approach. The empirical results indicate that the pass-through is incomplete during both periods, though, it is larger during the pre-liberalization period. The study further reveals that the banking crises lead to an increase in the lending rate in the long and short run. The effect of the crises on the deposit rate is also positive but only significant in the short run. The empirical analysis demonstrates that all the threshold cointegration tests for the two sample periods exhibit asymmetric behaviour. The retail loan/lending rate adjustment to changes in the policy rate during both periods appears asymmetric with upward rigidity. The finding supports the adverse customer reaction hypothesis, suggesting that banks are more rigid in raising loan rates than reducing them. The results also support customer reaction on the deposit side, showing among others, downward rigidity in deposit rates in both periods. Therefore, the study recommends that the monetary authorities should strengthen monetary operations to ensure efficient transmission of monetary policy rate. There is also a need for measures that can enhance competitiveness in the banking sector and improve the efficacy of the interest rate channel. More commitments to preventing a systemic crisis in the industry and those that can effectively contain unavoidable ones are also desirable.

A study on the nonlinear dynamics of ASEAN financial integration

PurposeThis study examines the co-integration relationships between Association of Southeast Nations (ASEAN) stock indices as a way to assess the feasibility of policy initiatives to strengthen market integration in ASEAN and identify implications for portfolio investors.Design/methodology/approach The authors employ threshold co-integration tests and a non-linear autoregressive distributed lag (NARDL) model to study the asymmetric dynamics of ASEAN equity markets. The study’s data cover the 2009–2022 period for seven member states: Cambodia, Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam.FindingsThe authors find evidence supporting co-integration relationships; adjustment toward equilibrium is asymmetric in the short run and symmetric in the long run for these countries. While co-movement in ASEAN equity markets seems encouraging for initiatives seeking to foster financial integration in regional economies, the benefits for international portfolio diversification appear to be neutralized.Originality/valueThe issue of stock market integration is important among policymakers, investors and academics. This study examines the level of stock market integration in ASEAN during the 2009–2022 period. For this purpose, advanced co-integration techniques are applied to different frequencies of data (daily, weekly and monthly) for comparison and completeness. The empirical analysis of this study is conducted using the Enders and Siklos (2001) co-integration and threshold adjustment procedure. This advanced co-integration technique is superior compared to other co-integration techniques by permitting asymmetry in the adjustment toward equilibrium.

The regime switching evidence of financial-economic-political risk in Turkey

In recent time, Turkey could be said to have experienced different levels of Economic Risk, Financial Risk, and Political Risk from low- to high-level. This study investigates the linkage between country risks, namely Financial Risk, Economic Risk, and Political Risk (FEP risk) in Turkey for the period 1984Q1 to 2019Q1 by using threshold cointegration, Markow-switching regression (given the nonlinearity and structural breaks observed in the time series variables), and frequency domain causality approaches. The empirical findings of this study reveal that (i) nonlinear cointegration between Economic Risk, Financial Risk, and Political Risk in Turkey is statistically significant given the evidence of threshold cointegration test, which determines the structural breaks endogenously; (ii) there is positive linkage among the component of country risk at different volatility periods; (iii) there is a significant Granger causal linkage between Economic Risk, Financial Risk and Political Risk at the different frequency levels. The study is likely to open debate about the literature since the study concludes with a discussion on short-run and long-run implications for economic, political, and financial stabilises, thus offering policy suggestions for the policymakers in Turkey.
