Abstract

In an intertemporal decision framework, borrowing and wealth holding decisions will incorporate information relevant to future income realizations. One channel for monetary and real disturbances to influence real activity is through revised anticipations of future income. In this study, evidence was uncovered for contemporaneous nominal shock effects on changes in household leverage with nominal and real shock effects uncovered for the growth of nondurables and services consumption and real financial wealth holdings. Evidence was found for potential opportunities to use short‐run monetary policy to offset the impact of sectoral production shocks on the growth rate or the volatility of the growth rate in consumption. The monetary shock would have to be opposite in sign to the sectoral production shock. A similar feature was found for the financial asset holdings. Evidence was uncovered for volatility and growth rate trade‐offs.

Abstract

This article questions the validity of regression models when high correlations exist between independent variables and presents the application of VAR as an alternative technique through the comparison of two groups of selected stocks that represent components of Dow Jones and S&P 500 indices, respectively. The results indicate that panel regressions face serious specification problems, while the impulse response function underlines that the shock to the volume innovation has a mostly positive impact on the volatility in both S&P and Dow Jones sample, but the tendency cannot be easily accounted for. The positive impact of volatility shocks on the inter market depth is rather unexpected, but it may be associated with an increase in volume that does not enormously enhance the spread up to the point where it will be too costly for market‐makers to trade, and accordingly, quickly narrows the spread to absorb new liquidity influx in the market. In the Granger causality tests Dow Jones stocks with comparatively larger average volume depth values and price levels provide slightly stronger relations between analyzed variables compared to the stocks included in the S&P sample.

Abstract

Using unpublished time‐series data for three specific age/gender groups, we first determine the percentage of female employment to total employment for nine sectors of the U.S. economy. Second, we estimate the cyclical change in hours of employment for each age/gender group within each sector. Third, we estimate the cyclical behavior of the nominal wage for each sectoral gender group. The paper’s evidence does not support, in general, a more cyclical response of female hours worked in the service‐producing sectors that are dominated by women. We find partial evidence that hours worked by men are more cyclical compared with hours worked by women in the male‐dominated goods‐producing sectors. Given the evidence of no pronounced difference in the cyclical behavior of hours and wages for men and women, the business cycle is gender‐neutral.That is, the elastic female labor supply is washed out over the business cycle across major sectors of the U.S. Economy. Observational evidence suggests supply‐side and structural factors in the economy have attenuated the business cycle, especially in the service‐producing sectors.

Abstract

Purpose

The main aim of this paper is to empirically test at market level, the investors' differential reaction to information, contribution of their confidence level and adaptive behaviour to excessive market volatility in Indian stock market.

Design/methodology/approach

The Bivariate Vector Autoregression and Impulse Response Analysis are used to study whether investors over/under-react to private and public information. EGARCH models are used to study the contribution of investors' over/under-confidence and adaptive behaviour to excessive market volatility.

Findings

The investors over-react to private information and under-react to public information during pre-crash period, become overconfident and contribute to excessive volatility. They under-react to both private and public information during after-crash period, become under-confident and also conform to adaptive market hypothesis (AMH).

Research limitations/implications

The empirical results of the study can help investors to minimize the negative impact of over/under-confidence on their expected utility.

Practical implications

The investors shall perform a post-analysis of investment, become aware of their past behavioural mistakes and start adapting to changing market conditions. This shall move the markets towards a new equilibrium in long run thus conforming AMH. However, the investors sometimes display an apparently irrational behaviour during this process.

Originality/value

To the best of the author's knowledge, this is the first study at market level data examining investors' over/under-reaction, over/under-confidence and adaptive behaviour in the context of stock market crash.

Abstract

Purpose

The study is intended to identify the macroeconomic factors that drive the use of companies registered in tax havens to purchase properties in the UK housing market.

Design/methodology/approach

Adopts an empirical study that uses Cointegration and Vector Autoregressive models to identify the influence or the motivations of using tax havens regime and its relationship with investment volume by analysing impulse responses of innovations to external and domestic factors.

Findings

The model uses monthly data for the period 1996–2019. This provides sufficient evidence that offshore buyers are particularly motivated by exchange values and the quality of governance in host economies.

Research limitations/implications

There is much to be revealed from the spatial distribution of this phenomena and the welfare effect at the micro-level.

Originality/value

To the best of my knowledge there is limited to no empirical study that primarily focus on the use of tax haven as an offshore investment tool in the UK housing market. The study also uses new dataset, Overseas Companies Ownership Dataset in the UK to understand housing ownership patterns by companies that are registered abroad dubbed, offshore buyers.

Abstract

Purpose

The purpose of this paper is to calculate the Hugoniot relations of polyurea; also to investigate the atomic-scale energy change, the related chain conformation evolution and the hydrogen bond dissociation of polyurea under high-speed shock.

Design/methodology/approach

The atomic-scale simulations are achieved by molecular dynamics (MD). Both non-equilibrium MD and multi-scale shock technique are used to simulate the high-speed shock. The energy dissipation is theoretically derived by the thermodynamic and the Hugoniot relations. The distributions of bond length, angle and dihedral angle are used to characterize the chain conformation evolution. The hydrogen bonds are determined by a geometrical criterion.

Findings

The Hugoniot relations calculated are in good agreement with the experimental data. It is found that under the same impact pressure, polyurea with lower hard segment content has higher energy dissipation during the shock-release process. The primary energy dissipation way is the heat dissipation caused by the increase of kinetic energy. Unlike tensile simulation, the molecular potential increment is mainly divided into the increments of the bond energy, angle energy and dihedral angle energy under shock loading and is mostly stored in the soft segments. The hydrogen bond potential increment only accounts for about 1% of the internal energy increment under high-speed shock.

Originality/value

The simulation results are meaningful for understanding and evaluating the energy dissipation mechanism of polyurea under shock loading, and could provide a reference for material design.

Abstract

Purpose

Despite the growing recognition of the complex interplay between macroeconomic shock indexes and stock market dynamics, there is a significant research gap concerning their interconnectedness and return spillovers in the context of the African stock market. This leaves much to be desired, given that the financial market in Africa is arguably one of the most preferred destinations for hedge and portfolio diversification (Alagidede, 2008; Anyikwa and Le Roux, 2020). Further, like other financial markets across the globe, the increased capital flow, coupled with declining information asymmetry in Africa, has deepened intra and inter-sectoral integration within and across national borders. This has, thus, increased the susceptibility of financial markets in Africa to spillover of shocks from other sectors and jurisdictions. Additionally, while previous studies have investigated these factors individually (Asafo-Adjei et al., 2020), with much emphasis on developed markets, an all-encompassing examination of spillovers and the connectedness between the aforementioned macroeconomic shock indexes and stock market returns remains largely unexplored. This study happens to be the first to consider the impact of each of the indexes on stock returns in Africa, with evidence spanning from May 2007 to April 2023, covering notable global crisis episodes such as the Global Financial Crisis (GFC), the COVID-19 pandemic and the Russia–Ukraine war.

Design/methodology/approach

This study employs the novel quantile vector autoregression (QVAR) model, making it the first of its kind in literature. By applying the QVAR, the study captures the potential nonlinear and asymmetric relationship between stock returns and the factors of interest across different quantiles, i.e. bearish, normal and bullish market conditions. Thus, the approach allows for a more accurate and nuanced examination of the tail dependence and extreme events, providing insights into the behaviour of the variables under extreme events.

Findings

The study revealed that connectedness and spillovers intensified under bearish and bullish market conditions. It was also observed that, among the macroeconomic shock indicators, FSI exerted the highest influence on stock returns in Africa in both bullish and normal market conditions. Across the various market regimes, the Egyptian Exchange (EGX) and the Nairobi Stock Exchange (NSE) were net receiver of shocks.

Originality/value

This study happens to be the first to consider the impact of each of the indexes on stock returns in Africa, with evidence spanning from May 2007 to April 2023, covering notable global crisis episodes such as the GFC, the COVID-19 pandemic and the Russia–Ukraine war. On the methodology front, this study employs the novel QVAR model, making it one of the few studies in recent literature to apply the said method.

Abstract

Purpose

This study aims to revisit the stock price–volume relations, providing new evidence from the emerging market of Qatar. In particular, three main issues are examined using both aggregate market- and sector-level data. First, the return–volume relation and whether or not this relation is asymmetric. Second, the common characteristics of return volatility; and third, the nature of the relation between trading volume and return volatility.

Design/methodology/approach

The study uses the OLS and VAR modeling approaches to examine the contemporaneous and dynamic (causal) relations between index returns and trading volume, respectively, while an EGARCH-X(1,1) model is used to analyze the volatility–volume relation. The data set comprises daily index observations and the corresponding trading volumes for the entire market and the individual seven sectors of the Qatar Exchange (i.e. banks and financial services, consumer goods and services, industrials, insurance, real estate, telecommunications and transportation).

Findings

The empirical analysis reports evidence of a positive contemporaneous return–volume relation in all sectors barring transportation and insurance. This relation appears to be asymmetric for all sectors. For the market and almost all sectors, there is no significant causality between returns and volume. By and large, these findings lend support for the implications of the mixture of distributions hypothesis (MDH). Lastly, the information content of lagged volume seems to have an important role in predicting the future dynamics of return volatility in all sectors, with the industrials being the exception.

Practical implications

The findings provide important implications for portfolio managers and investors, given that the volume of transactions is generally found to be informative about the price movement of sector indices. Specifically, tracking the behavior of trading volume over time can give a broad portrayal of the future direction of market prices and volatility of equity, thereby enriching the information set available to investors for decision-making.

Originality/value

Based on both market- and sector-level data from the emerging stock market of Qatar, this study attempts to fill an important void in the literature by examining the return–volume and volatility–volume linkages.

Abstract

The purpose of this study is to provide down-to-earth macroeconomic policy implications from the up-to-date estimates of the trade system in the OECD countries. Understanding on the linkages between the world trade mechanism and the macroeconomy is of utmost importance for the post-crisis managements of the world economy, the major points regarding the macroeconomic policy implications are as follows.

(1) For the majority of the OECD countries, fiscal expansion is likely to encourage the world trade when it is designed in the way to increase private consumption, in fact, only in a few countries fiscal expansion can increase the world trade volumes in its own right.

(2) Currency depreciation might be an attractive policy option for improving trade balances in the cases of the 9 OECD countries.

(3) There is a clear evidence of pricing-to-market with cross-country diversity, implying that import or domestic price robustness from the external forces.
