Abstract

Purpose

The relationship between returns and trading volume is central in financial economics because it has both a theoretical interest and important practical implications with regard to the structure of financial markets and the level of speculation activity. The aim of this study is to provide new insights into the association between returns and trading volume by investigating their kernel (instantaneous) causality. The empirical analysis relies on time series data from 22 commodities futures markets (agricultural, energy and metals) in the USA.

Design/methodology/approach

Non-parametric (local linear) regressions are applied to daily data on returns and on trading activity; generalized correlation measures are computed and their differences are subjected to formal statistical testing.

Findings

The results suggest that raw returns are likely to kernel-cause volume and volume is likely to kernel-cause price volatility. The patterns of causal order are generally in line with what is stipulated by the relevant theory, they provide guidance for model specification and they appear to explain the empirical evidence on temporal (lag-lead) causality between the same pairs of variables obtained in earlier works.

Originality/value

The concept of kernel causality has very recently become a part of the toolkit for econometric/statistical analysis. To the best of the author’s knowledge, this is the first study that relies on the notion of kernel (instantaneous) causality to provide new evidence on a relationship that is of keen interest to investors, professional economists and policymakers.

Abstract

This is a survey paper of the recent literature on the application of semiparametric–econometric advances to testing for functional form of the environmental Kuznets curve (EKC). The EKC postulates that there is an inverted U-shaped relationship between economic growth (typically measured by income) and pollution; that is, as economic growth expands, pollution increases up to a maximum and then starts declining after a threshold level of income. This hypothesized relationship is simple to visualize but has eluded many empirical investigations. A typical application of the EKC uses panel data models, which allows for heterogeneity, serial correlation, heteroskedasticity, data pooling, and smooth coefficients. This vast literature is reviewed in the context of semiparametric model specification tests. Additionally, recent developments in semiparametric econometrics, such as Bayesian methods, generalized time-varying coefficient models, and nonstationary panels are discussed as fruitful areas of future research. The cited literature is fairly complete and should prove useful to applied researchers at large.

Abstract

It is known that model averaging estimators are useful when there is uncertainty governing which covariates should enter the model. We argue that in applied research there is also uncertainty as to which method one should deploy, prompting model averaging over user-defined choices. Specifically, we propose, and detail, a nonparametric regression estimator averaged over choice of kernel, bandwidth selection mechanism and local-polynomial order. Simulations and an empirical application are provided to highlight the potential benefits of the method.

Abstract

Purpose

The purpose of this paper is to investigate the endogeneity of asset values and how it relates to farm financial stress in US agriculture. The authors conceptualize an implied measure of farm financial stress as a function of debt position. The authors posit that there are variations in the asset values that are beyond the farmer’s control and therefore have implications on farm debt.

Design/methodology/approach

The framework recognizes the endogeneity of return on assets (ROA). It uses a non-parametric technique to approximate the variance of expected ROA (VEROA). The authors model the rate of return on agricultural assets and interest rate with a formulation that focuses on macroeconomic policy. Further, the authors use a dynamic balanced panel data set from 1960 to 2011 for 15 US agricultural states from the Agricultural Resource Management Survey, and information from traditional state-level financial statements.

Findings

Estimation of linear dynamic debt panel data models accounting for the endogeneity of ROA and VEROA is a challenging task. Estimated variances are unstable. Hence, the authors focus on variance specification that uses the residuals squared from the ARIMA specification and non-parametric estimators. Arellano-Bover/Blundell-Bond generalized method of moments estimation procedures, although may be biased, show that VEROA has a negative and significant effect on the total amount of debt in the agricultural sector.

Research limitations/implications

The instruments used in this analysis are lagged regressors which may be weakly correlated with the relevant first-order condition, hence not properly identifying the parameters of interest. Future research could include the identification of better instruments, potentially use of sequential moment conditions.

Originality/value

Unlike previous study, the authors use non-parametric approximation of VEROA. The authors model the rate of return on agricultural assets and interest rate with a formulation that focuses on macroeconomic policy. Second, the authors make use of a large dynamic balanced panel data set from 1960 to 2011 for 15 agricultural states in the USA. To the best of the authors’ knowledge, this study is one of the few that provides evidence on risk-balancing behavior at the agricultural sector level, of the USA.

Abstract

Purpose

The purpose of this paper is to provide an overview on the state of the field in intercultural dynamics on competition and cooperation at the individual, team, and organizational levels. The authors integrate previous studies from multiple disciplines to articulate the contextual importance of intercultural dynamics. The authors also suggest three overarching themes to expand the field of research on intercultural dynamics.

Design/methodology/approach

The authors use an integrative literature review to articulate the importance of intercultural dynamics, provide an introduction to the new contributions in this special issue, and propose new directions for future research.

Findings

Intercultural dynamics research has the potential to expand in three overarching areas: constructive controversy, collaborative communication, and global competency and identity at multiple levels.

Research limitations/implications

Intercultural dynamics is still a nascent field emerging from cross-cultural and strategic management. The authors hope the review lays the groundwork for more studies on intercultural dynamics at the interpersonal, team, organizational, and mixed levels of analysis in both theory building and empirical works.

Practical implications

Understanding intercultural dynamics in competition and cooperation can help individuals and managers in multinationals and born global organizations navigate cultural complexity and foster cooperation.

Social implications

The authors hope the ideas on intercultural dynamics can facilitate collaboration and reduce conflict in intercultural encounters at the individual, organization, and societal levels.

Originality/value

This paper offers an overview on the state of the field and lays groundwork for more systematic inquiries on intercultural dynamics in competition and cooperation.

Abstract

Purpose

The purpose of this study is to investigate the effect of electromigration (EM) on solder alloy joint on copper with nickel surface finish. Sn-Bi solder alloy has been used in this research.

Design/methodology/approach

The EM process was completed with the duration of 0, 24, 48, 72 and 96 h under direct current (DC) of 1,000 mA. Tensile stress on the substrates was assessed after EM at a tension rate of 0.1 mm/min. Microscopy was used to observe the formation and size of voids and conduct an analysis between copper and nickel substrates.

Findings

Four types of intermetallic compounds (IMCs), namely, Cu-Sn, Cu3Sn, Cu6Sn5, and Sn-Bi, were detected between the Sn-Bi/Co solder joint. Voids appear to be at the anode and the cathode for 96 h of EM for Sn-Bi/Ni solder join; however, there seem to be more voids at the cathode.

Originality/value

EM is one of the crucial keys to produce a good integrated circuit (IC). When the current density is extremely high and will cause the metal ions to move into the electron direction flow, it will be characterised based on the ion flux density. In this research, the effect of EM on the Sn-Bi solder alloy joint on copper with nickel surface finish was studied.

Abstract

Purpose

Hospitality workers are emotional labor workers because they must display appropriate emotions to their customers to provide outstanding service. Emotional intelligence (EI) helps employees regulate their emotions and display appropriate emotions, and hence should help hospitality workers provide outstanding service. However, the strength of the relationship between EI and hospitality workers’ job performance substantially varied across studies. Hence, the purpose of the present study is to clarify the mixed findings and to examine if EI can improve hospitality workers’ job performance.

Design/methodology/approach

A meta-analysis was performed to investigate the relationship between EI and hospitality workers’ job performance as well as the moderators which condition this relationship.

Findings

The present meta-analysis indicated that EI is positively related to hospitality workers’ job performance (ρ̅̂ = 0.54); the relationship between EI and hospitality workers’ job performance is stronger when the percentage of married subjects is low and in feminine cultures; and this relationship does not differ between male-dominated and female-dominated studies, across educational levels, between collectivistic and individualistic cultures, between low and high power distance cultures and between low and high uncertainty avoidance cultures.

Research limitations/implications

This study uncovers theoretically important moderators that contribute to cross-cultural research, work–family literature and gender-related literature in hospitality research.

Originality/value

The present study builds a theoretical foundation and performs a meta-analysis to elucidate the relationship between EI and hospitality workers’ job performance and to identify the moderators which condition this relationship.

Abstract

The study of 5-year-old children with symptoms of attention-deficit hyperactivity disorder (ADHD) is important because it provides an opportunity to discover early intervention strategies for children who are expected to develop severe problems later in life. This chapter presents a research program intended to develop assessment and interventions tools for kindergarten children. Specifically, we present two rating scales (one for teachers and one for parents), two neuropsychological tests, and an intervention program intended to promote controlled attention and working memory. Finally, we present an investigation, with a small group of 5-year-old children with ADHD symptoms, validating the program.
