Abstract

Purpose

The purpose of this paper is to empirically analyze the dynamic relationship between stock market and bond market based on the effect of different information shocks.

Design/methodology/approach

This paper decomposes the information of stock market and bond market into public information and private information. The characteristics of response of stock market and bond market to the information shocks are examined by SVAR model and modified BEKK model.

Findings

The study shows that the information shocks in financial market yield not only the effect on linear asset return but also the effect on nonlinear asset volatility. The public information mainly produces a short effect of return while the private information mainly produces a permanent effect on volume. The interactive relation between stock market and bond market is mainly reliant on the effect of the information shock volatility to market return volatility.

Originality/value

The paper empirically analyzes the influence characteristics of different information shocks, which has some reference value not only for deeply understanding the market microstructure but also for improving the construction of various capital markets.

Abstract

Purpose

Since 2008, bitcoin has continued to attract investors due to its growing capitalization and opportunity for speculation. The purpose of this paper is to analyze the impact of bitcoin (BTC) on gold, the volatility index (VIX) and the dollar index (USDX).

Design/methodology/approach

The series used are weekly and cover the period from January 2016 to November 2022. To generate the results, the unrestricted vector autoregression (VAR), structural vector autoregression (SVAR) and wavelet coherence were performed.

Findings

The findings are mixed as not all tests show the exact effects of BTC in the three asset classes. However, common to all the tests is the significant influence that BTC maintains on gold and vice versa. The positive shock in BTC significantly increases the gold prices, confirmed in three different tests. The effects on the VIX and USDX are still being determined, where in some tests, it appears to be influential while in others not.

Originality/value

BTC’s diversification potential with equity stocks and USDX makes it a valuable security for portfolio managers. Furthermore, regulatory authorities should consider that BTC is not an isolated phenomenon and can significantly influence other asset classes such as gold.

Abstract

Purpose

This study investigates the spillover effects between exchange rate changes and stock returns in China. The authors find that no significant interconnections exist between stock returns and exchange rates changes.

Design/methodology/approach

Although the conventional structural VAR (SVAR) approach fails to examine the contemporaneous effects, the Markov switching SVAR model captures the volatile structure of the Chinese financial market. The regime-switching estimates indicate that volatile structure tends to be significant during two financial crisis periods.

Findings

Notwithstanding the fact that exchange rate changes cannot Granger-cause stock returns in the long run, its contemporaneous spillover effects on stock returns are found to be statistically significant.

Originality/value

This study aims to shed light on the spillover effects between exchange rate changes and stock returns in China, as the Chinese currency is becoming flexible and China’s stock market has undertaken important reforms. The spillovers between the two markets are of topical importance due to the increasing connections between China and the global economy.

The purpose of this study is to examine oil price shocks on US shale oil supply and energy security during the period 2000q1–2020q4.

Abstract

Purpose

The purpose of this study is to examine oil price shocks on US shale oil supply and energy security during the period 2000q1–2020q4.

Design/methodology/approach

In this study, the Shannon–Wiener index was used to calculate energy security, and then a structural vector autoregression (VAR) was applied to measure the effect of oil price shocks.

Findings

The results of the variance decomposition indicate that oil prices account for about 20% of changes in US shale oil production, while it explains only about 3% of changes in energy security. Finally, historical decomposition confirms the results of impulse response functions.

Originality/value

The novelty of this study is that so far, no study has examined the effect of oil price shock on shale oil production and energy security in the USA using the structural VAR model. This study also used the latest Shannon–Wiener index as a measure of energy security in the USA. The reason for selecting this index is that, in addition to considering the share of the total consumption of each primary energy, the share of energy imports from each country as well as the political risk of energy exporting countries to the USA are also included.

Abstract

Purpose

The purpose of this paper is to study the short‐term macroeconomic effects of the fiscal policy in Colombia for the 1980‐2007 period using a structural vector autoregression (SVAR) model.

Design/methodology/approach

The authors' benchmark is a five‐variable SVAR model which includes government spending, output, tax revenues, inflation and short‐term interest rates. In addition, the authors specified six‐variable VAR models, adding in turn private consumption, private investment, the unemployment rate and the real minimum wage to the last set of variables. Two alternative identification techniques are used in the VARs to check the robustness of the results.

Findings

The following effects of a positive government spending shock are found. First, the GDP responds positively and significantly during the first six quarters. The cumulative output multiplier fluctuates between 1.12 and 1.19. Second, both inflation and nominal interest rates respond positively and significantly. Third, the authors find a significant positive response by both private consumption and private investment. Finally, the unemployment rate reacts negatively and significantly.

Research limitations/implications

The most surprising result comes from the response of output to a positive shock in taxes. Nonetheless, the positive respond of the GDP is short lived and has little significance.

Practical implications

The authors' results support the smoothing role of fiscal policy on output fluctuations, which implies its capacity to restore real activity effectively in critical times like the ones currently being forecast.

Originality/value

The negligible results found previously for Colombia could be related to the fiscal data used, which are not keep coherence with national accounting. To solve these obstacles, a quarterly fiscal database is assembled on an approximately accrual basis for the general government.

This study aims to focus on two-way interaction between monetary policy and house prices in emerging economies.

Abstract

Purpose

This study aims to focus on two-way interaction between monetary policy and house prices in emerging economies.

Design/methodology/approach

This study uses panel structural vector autoregressive model.

Findings

The results show that real house prices decrease in response to a contractionary monetary policy shock. However, relative to advanced economies, the reaction of the prices is limited in emerging economies, pointing out the structural differences in emerging economies including the small size of the mortgage market and the lack of a well-functioning secondary market in housing finance. This study further finds that monetary policy is tightened in response to a positive shock to house prices. However, this response is also weak when compared to that response in advanced economies.

Research limitations/implications

These findings suggest that house price developments should not be prior target for monetary policies in emerging economies unless they become problem for financial stability or inflationary concerns.

Originality/value

Using a sample of inflation targeting emerging countries, this study contributes to the literature by conducting both panel setting and single-country analysis to explore the two-way dynamic relationships between the monetary policy and housing market in emerging economies.

Abstract

Purpose

The purpose of this paper is to re‐examine the structural origins of international crude oil price fluctuation.

Design/methodology/approach

The paper establishes a structural vector autoregression model based on the generalized supply and demand analysis of crude oil price fluctuation and performance the structural decomposition of price shocks with impulse response analysis of those factors.

Findings

It is found that four kinds of structural shocks derived from the generalized supply and demand analysis are the essential determinants of crude oil prices fluctuation. On one hand, similar to Kilian's results, the supply side shocks – both the exogenous geopolitical ones and other oil supply shocks have little influence. Whereas, the demand side shocks – both the aggregate demand shock and the oil market specific demand shock have prominent effects. On the other hand, with the expanded sample range, it is found that the dynamic characteristic of the impulse response of oil price to demand side factors is not only incompatible with the basic economic theory, but also clashes with Kilian's statement based upon his research. It is conjured that the incompatibility comes from the ignorance of the finer decomposition of demand side factors. To decompose those demand side factors further, the US dollar liquidity was added into the model. The results show that the impact of US dollar liquidity on the fluctuation of oil prices cannot be ignored. The argument that ascribes the soaring international crude oil price to China's economic growth lacks theoretical and empirical evidence.

Originality/value

The paper contributes marginally to the research on the structural origins of international crude oil price fluctuation and sheds light on the possibility of finer decomposition of demand side oil shocks.

This paper aims to investigate the relationship between oil price shocks and world food prices between 1974 and 2018.

Abstract

Purpose

This paper aims to investigate the relationship between oil price shocks and world food prices between 1974 and 2018.

Design/methodology/approach

The authors use the SVAR model to disentangle the oil price into supply, aggregate demand and oil-specific demand shocks and apply the detrended cross-correlations analysis to measure the association between oil price shocks and food returns/volatility and analyze contagion effects between oil and food markets.

Findings

The results show that the correlations between oil and food prices depend on whether oil prices changes are driven by supply or demand shocks. Particularly, food returns (volatility) are positively (negatively) more dependent on the oil price changes driven by aggregate demand (oil specific demand) shocks. Further analysis dealing with contagion analysis between oil and food markets shows a contagion effect during the food crisis of 2006–2008. Oil-specific demand shocks are the main source of this phenomenon.

Research limitations/implications

This study differentiates itself from the previous literature by simultaneously disentangling oil price into supply, aggregate demand and oil-specific demand-driven shocks and evaluating the cross-correlations between each shock type and food returns/volatility. Specifically, this study has the originality of detecting the main source of contagion effects between oil and food markets over the food crisis of 2006–2008.

Practical implications

The results of this study are important for policymakers and investors. They should account for the oil price fluctuations differently depending on whether the oil price shocks are driven by the demand or supply side. Moreover, they should anticipate an increase (decrease) in food prices due to a positive (negative) oil shock. In addition, special attention should be accorded to the world oil demand. Finally, when a food crisis occurs, markets operators should focus more on the specific oil-demand shocks, as it is the most contributor to possible contagion effects between oil and food markets.

Originality/value

This study differentiates itself from the previous literature by simultaneously disentangling oil price into supply, aggregate demand and oil-specific demand-driven shocks and evaluating the cross-correlations between each shock type and food returns/volatility. Specifically, this study has the originality of detecting the main source of contagion effects between oil and food markets over the food crisis of 2006–2008.

This paper aims to examine the interrelationships of monetary policy's structural shocks, the real exchange rate and stock prices.

Abstract

Purpose

This paper aims to examine the interrelationships of monetary policy's structural shocks, the real exchange rate and stock prices.

Design/methodology/approach

According to quarterly data, variables such as gross domestic product, consumer price index, the real exchange rate, stock price and monetary policy indices in the structural vector autoregressions model are estimated. These variables' volatility is attributed to other variables’ structural shocks separately, and analysis of variance tables for all variables is presented.

Findings

The results show that structural shock on the exchange rate does not affect the stock price, but the monetary policy's structural shock positively impacts the real exchange rate. Moreover, the real exchange rate and monetary policy's structural shocks have a negative impact on the stock price index. However, no significant effect is found pertain to the real exchange rate structural shock, statistically.

Originality/value

To the best of the authors’ knowledge, the current study model is relatively novel in developing countries, and the study sought strength to develop knowledge on the subject of the study.
