The purpose of this paper is to compare the short‐term trading behaviour of A shares owned by domestic investors and their dually‐traded B shares owned by foreign investors, after a period of significant price change.

Given that the fundamentals of A and B shares are the same, the paper tests the hypothesis that both types of stocks should behave homogeneously either by exhibiting a momentum behaviour or an over‐reaction pattern. The paper relates any deviations in post‐shock stock returns to the differences in the trading patterns of foreign relative to domestic investors.

While the prices of the A shares are relatively random after the event, those of the B shares carry on increasing significantly after both positive and negative shocks. This trend is more pronounced for large firms with high liquidity, in contrast to the efficient market hypothesis expectations, which suggests that any abnormal performance should be arbitraged away sooner in a frictionless (in this case liquid) market.

The paper relates these results to the high level of optimism of foreign investors, which is an under‐researched area in behaviour finance.

Several studies focus on asymmetric impact of shocks on conventional stocks. However, only few studies explore Islamic stocks, but none has examined the asymmetric impact of shocks on Islamic stocks. This study aims to fill the gap by investigating the asymmetric impact of shocks on Islamic stocks. Specifically, it identifies the effect of good and bad news on Islamic stock market. The study also aims to examine the returns and volatility spillover effects across different Islamic markets.

To carry out the empirical analysis, the authors have applied the exponential generalized autoregressive conditional heteroscedasticity (ARCH) model on daily Islamic stock indices of 18 countries. The study covers the period from July 2009 to July 2016. The authors have started their empirical analysis by examining the time series properties and testing the presence of ARCH effects. Further, the authors have applied several post-estimation tests to ensure the robustness of the results.

The results indicate that there is significant leverage effect in Islamic stocks traded in the sampled countries. That is, negative shocks or bad news have stronger effects on Islamic stock returns’ volatility as compared to positive shocks or good news. The authors also found that there are significant mean spillover effects for the examined countries. This finding implies that increased Islamic stock returns in country have significant and positive effects in Islamic stocks’ returns in another other. Similarly, the results regarding the volatility spillover effects suggest that there are significant volatility spillover effects across all examined countries. However, the authors found both positive and negative volatility spillover effects. It should also be noted that in some cases, the authors did not find any significant volatility spillover effect.

The findings of this study have several important policy implications for both investors and policymakers. As the findings suggest that Islamic stock indices are integrated across countries both in terms of returns (mean) and risk (volatility), they are useful for investors to design well-diversified portfolios. The significant volatility spillovers suggest policymakers to design such policy that may help in reducing the adverse effects of increased volatility of Islamic stock of other/foreign countries on the Islamic stocks of the home countries. The significant evidence of the presence of leverage (asymmetric) effects suggest investors to use effective and active hedging instruments to hedge risk, particularly, in bad times.

Unlike other studies on Islamic stocks, this study takes into account the asymmetric effects of positive and negative shocks. Further, the study examines the mean and variance spillover effects for a large panel of countries having Islamic stocks. Finally, several pre- and post-estimation tests are applied to ensure the robustness of the results.

This study examines the influence of the global geopolitical risk (GPR) on the relationship between oil prices and domestic food prices under the augmented Phillips curve framework.

Using monthly data on Nigeria from January 1995 to December 2021, the authors accommodate symmetry and asymmetry by adopting the linear and nonlinear autoregressive distributed lag, linear and nonlinear Granger causality tests.

The study establishes the positive and significant effects of both oil prices and GPR on food prices in the long and short run, though with a small magnitude in the short run. The asymmetric model shows that, while oil price shocks (positive and negative) exert a positive influence on food prices in the long-run, the effects of oil price shocks differ when accounting for GPR in the short-run. The coefficients of the interactive term, being the moderator of GPR between oil-food prices, are positively significant across models, suggesting that they jointly influence food prices when assuming linearity. The nonlinear model shows that the positive and negative components of interactive terms exert a positively significant influence on food prices, even though food prices tend to be more reactive to positive oil price shocks. The robustness checks show a unidirectional causal flow from oil prices and GPR to food prices under the linear and nonlinear models.

The authors examine the moderating effect of the newly developed global GPR index of Caldara and Iacoviello (2022) on the oil–food inflation relationship in Nigeria by applying the symmetric and asymmetric approaches.

The purpose of this paper is to investigate the possible asymmetric response of inflation expectations to oil price and policy uncertainty shocks.

The authors used the test of asymmetric impulse responses proposed by Kilian and Vigfusson (2011) to explore the issue of asymmetry.

Unlike other studies that assume symmetric effects, this study finds asymmetric effects of oil price and policy uncertainty on inflation expectations for positive and negative shocks and for pre- and post-financial-crisis periods. In particular other things being same, a same magnitude oil price shock has greater effect on inflation expectations in post-crisis period than in pre-crisis period. Moreover, in post-crisis period a positive increasing oil price shock has greater effect on inflation expectations than a negative decreasing oil price shock.

The paper concludes that FED’s greater focus on output stabilization since financial crisis has made inflation expectations less anchored and a sudden surge in oil price may quickly trigger inflation through inflation expectations.

Exploring the issue of the possible asymmetric effects of oil price and economic policy uncertainty on inflation expectations is a relatively new topic (as other studies only assumed symmetry and did not investigate the possible asymmetry in this regard).

Using quarterly data for a sample of 17 industrial countries, the purpose of this paper is to study asymmetry in the face of monetary shocks compared to government spending shocks.

The paper outlines demand and supply channels determining the asymmetric effects of monetary and fiscal policies. The time‐series model is presented and an analysis of the difference in the asymmetric effects of monetary and fiscal shocks within countries is presented. There then follows an investigation of the relevance of demand and supply conditions to the asymmetric effects of monetary and fiscal shocks. The implications of asymmetry are contrasted across countries.

Fluctuations in real output growth, price inflation, wage inflation, and real wage growth vary with respect to anticipated and unanticipated shifts to the money supply, government spending, and the energy price. The asymmetric flexibility of prices appears a major factor in differentiating the expansionary and contractionary effects of fiscal and monetary shocks. Higher price inflation, relative to deflation, exacerbates output contraction, relative to expansion, in the face of monetary shocks. In contrast, larger price deflation, relative to inflation, moderates output contraction, relative to expansion in the face of government spending shocks. The growth of output and the real wage decreases, on average, in the face of monetary variability in many countries. Moreover, the growth of real output and the real wage increases, on average, in the face of government spending variability in many countries. Asymmetry differentiates the effects of monetary and government spending shocks within and across countries. The degree and direction of asymmetry provide a new dimension to differentiate between monetary and fiscal tools in the design of stabilization policies.

The paper's evidence sheds light on the validity of theoretical models explaining asymmetry in the effects of demand‐side stabilization policies. Moreover, the evidence should alert policy makers to the need to relax structural and institutional constraints to maximize the benefits of stabilization policies and minimize the adverse effects on economic variables.

The purpose of this paper is to examine the impacts of large income and expenditure shocks on household food expenditures and determines whether the impacts of large shocks differ among households, especially low-income households.

The study’s data are drawn from a household survey conducted in rural China. Multivariate analysis examines the impacts of large income and expenditure shocks on food expenditures.

The impacts of large positive income shocks on food expenditure are moderate. However, households reduce their per capita food expenditures within a range of about 25-30 percent after suffering large negative shocks. The greatest impact is found for shocks where expenditures more than double, followed by the impact of shocks where income declines by more than half. Moreover, food expenditures among low-income households are much more sensitive to large negative income and expenditure shocks. The paper concludes with policy implications.

This is the first Chinese study to empirically examine the impacts of different income and expenditure shocks on household food expenditures. The results have important implications for smoothing households’ food consumption after they suffer from shocks.

Climate change not only causes serious economic losses but also influences financial stability. The related research is still at the initial stage. This paper aims to examine and explore the impact of climate change on financial stability in China.

This paper first uses vector autoregression model to study the impact of climate change to financial stability and applies NARDL model to assess the nonlinear asymmetric effect of climate change on China’s financial stability using monthly data from 2002 to 2018.

The results show that both positive and negative climate shocks do harm to financial stability. In the short term, the effect of positive climate shocks on financial stability is greater than the negative climate shocks in the current period, but less in the lag period. In the long term, negative climate shocks bring larger adjustments to financial stability relative to positive climate shocks. Moreover, compared with the short-term effect, climate change is more destructive to financial stability in the long run.

The paper provides a quantitative reference for assessing the nexus between climate change and financial stability from a nonlinear and asymmetric perspective, which is beneficial for understanding climate-related financial risks.

This study examines the asymmetric effect of government spending on economic growth in Nigeria over the period 1980–2017. Specifically, this study investigates whether the response of economic growth to government spending shocks differs according to the nature of shocks on them. In addition, the authors examine whether the stabilizing effects of fiscal policies are dependent on the state of the business cycle.

The study adopts the linear fiscal reaction function in addition to the nonlinear regression model of Hatemi-J (2011, 2012), Granger and Yoon (2002), which allows us to separate negative shocks from positive shocks to government spending. Similarly, the authors adopt the generalized method of moments (GMM) techniques of Hansen (1982) to account for simultaneity and endogeneity problems inherent in dynamic model.

The authors’ findings reveal that there is evidence of asymmetry in the government spending–economic growth nexus in Nigeria over the period of study. Specifically, the authors find that the response of economic growth to government spending shocks differs according to the nature of shocks on them. More specifically, the study established that the stabilizing effects of fiscal policies are dependent on the state of the business cycle.

Unlike the traditional method of modeling asymmetry, which adopts the simple inclusion of a squared government spending term or by the inclusion of a cubic government spending term, the model adopted in this study allows us to model shocks and show how the responses of economic growth to government expenditure differ according to the nature of shocks on them.

This study aims to reveal new information about the relationship between energy consumption and economic growth for the time-varying causality.

Economic growth and renewable and nonrenewable energy consumption data of the G7 countries (Canada, France, Germany, Italy, Japan, the UK and the USA) for the 1980–2016 period were used in the study. The nonasymmetric causality test developed by Hacker and Hatemi-J (2006) and both traditional and time-varying forms of the asymmetric causality test by Hatemi-J (2012) were used as the study method.

While the study favors feedback hypothesis for renewable energy consumption in the nonasymmetric causality tests in the UK economy, it favors the same hypothesis for nonrenewable energy consumption in the US economy. However, according to the results reported by Hatemi-J (2012), the feedback hypothesis, which is supported for the UK, is supported only in positive shocks, yet not for each period of analysis. Similarly, feedback hypothesis, which is supported in the USA, is supported only in the negative shocks, yet not for each period of analysis.

This study examined that the asymmetric causality relationship between variables can be analyzed in time-varying form. Therefore, whether positive and negative shocks in renewable and nonrenewable energy consumption always provide useful information in estimations about economic growth is analyzed.

Employees need a sustainable career to prolong their working lives. The ability, motivation and opportunity to work form an important basis for sustainable careers across the lifespan. However, over the lifespan of their careers employees are likely to experience several career shocks (e.g. becoming chronically ill or being fired) which might result in unsustainable trajectories. This study aims to contribute to the literature on sustainable careers by unraveling the process through which careers shocks relate to career (un)sustainability and what role perceptions of human resource practices play in the process.

Thirty-three in-depth retrospective interviews with participants of 50 years and older were conducted and analyzed using a template analysis.

Results showed that career shocks influence career sustainability through a process of changes in demands or changes in resources, which in turn, relate to changes in person–job fit. When person-job–fit diminished, the ability, motivation and opportunity to continue working decreased, whereas when person–job fit improved, the ability, motivation and opportunity to continue working improved as well. Organizations appear to be able to diminish the negative consequences of career shocks by offering job resources such as HR practices in response to career shocks.

A limitation of this study is the retrospective nature of the interviews, which could have resulted in recollection bias.

This study gives HRM practitioners insight into the HR practices that are effective in overcoming career shocks.

This study extends existing literature by including career shocks as possible predictors of sustainable careers.
