Moderating Effects of Firm Age on the Relationship between Debt and Stock Returns

This article investigates the moderating effects of firm age on the relationship between debt and stock returns. The system generalized method of moment’s results indicate that firm age has a positive moderating effect on the relationship between book debt and stock returns. The results are robust, as firm age positively moderates the relationship between market debt and stock returns. Moreover, firm age has a direct positive effect on stock returns. Results suggest that as firms grow older, they use their experience to make effective capital structure decisions (i.e., optimal debt-equity mix) to maximize debt interest-tax-shield and increase shareholders’ returns.     

Seeing Borders Through the Lens of Structuration: A Theoretical Framework

Despite a growing body of work, scholars have rarely engaged with the classic divide of structure and agency in border studies. Drawing on theory of structuration by Anthony Giddens, this article proposes a theoretical approach and/or tool that views borders as the result of a continuous production and reproduction of structure(s) and agents. The framework offers an analysis of what makes each border distinct and of the performance of borderwork. The article briefly overviews major theoretical approaches in critical border studies, presents a brief summary of the theory of structuration, discusses the proposed theoretical framework for border studies, and presents a case study based on the recently exchanged Bangladesh-India border enclaves to demonstrate the application of this framework.     

Inspiring employees' ecological behaviors: The roles of corporate environmental strategy,biospheric values,and eco-centric leadership

The consequences of environmental degradation have steered organizations to promote pro-ecological behaviors among their employees, and achieving this effectively is paramount for business and environmental sustainability. Applying a multilevel integrated approach, this study investigates the impact of corporate environmental strategy, biospheric values, and eco-centric leadership on employees' ecological behaviors. A self-administered questionnaire was used to collect data from 289 employees from a cross section of industries in Bangladesh. The findings reveal the significant influences of environmental strategy and biospheric values on employees' ecological behaviors as well as the moderating role of eco-centric leadership. The study also provides some significant insights for formulating environmental strategy and inspiring employees' ecological behaviors in organizational contexts. Theoretical and managerial implications as well as future research directions have also been provided.     

Bitcoin—A hype or digital gold? Global evidence

This study explores whether Bitcoin constitutes as a hedging instrument whilst seeking portfolio diversification opportunities among sustainable, conventional and Islamic asset classes since Bitcoin emerges as a distinct alternative investment and asset class across the world. We apply multivariate generalised autoregressive conditional heteroscedastic-dynamic conditional correlation and continuous wavelet transforms based on the recent data set ranging from August 18, 2011, to September 10, 2018. First, our findings show that Bitcoin returns are mean-reverting which implies that its value tends to come down to mean value in the long run and not completely crushed to zero irrespective of price changes suggesting Bitcoin as a sustainable asset class. Second, the time-invariant model shows that Bitcoin offers portfolio diversification opportunities with almost all equity indices, in particular, Dow Jones Islamic followed by FTSE 4 Good index. Finally, the time-variant analysis reconfirms that Bitcoin offers portfolio diversification benefits both in the short and long run. These findings carry meaningful policy considerations for fund managers and cross-country investors.     

The long-run impact of Information and Communication Technology on economic output: The case of Australia

This paper investigates the cointegration and causal relationships between Information and Communication Technology (ICT) and economic output in Australia using data for about five decades. The framework used in this paper is the single-sector aggregate production function, which is the first comprehensive approach of this kind to include ICT and non-ICT capital and other factors to examine long-run Granger causality. The empirical evidence points to a cointegration relationship between ICT capital and output, and implies that ICT capital Granger causes economic output and multifactor productivity, as does non-ICT capital.     

TRIBUTE: Trip-based urban transportation emissions model for municipalities

This research aims at developing modeling and scenario-comparison tools to explore the impacts of various transportation and land use planning policies on changing travel behavior and eventually greenhouse gas (GHG) emissions. A Trip-Based Urban Transportation Emissions (TRIBUTE) model is developed. Data required for TRIBUTE comes from household travel surveys and emissions inventories, which is a major advantage in cases where a detailed transportation network model is unavailable. TRIBUTE is composed of two main parts: a mode choice model and an emissions forecasting model. The mode choice model is responsible for estimating modal shares of alternative modes of travel in response to changes in personal, modal, and land use attributes. The emissions forecasting model translates the modal shares into vehicle kilometers traveled, and subsequently GHG emissions. TRIBUTE is a macroscopic model intended to assist municipalities evaluate alternative transportation and land use policy scenarios and eventually select the one(s) that help them meet their future GHG emission targets. This paper reports on the conceptual framework of the developed model and presents a case study.     

The effects of human capital composition on technological convergence

This paper empirically investigates whether the contribution of human capital to productivity growth depends on the composition of human capital and proximity to the technology frontier in a panel of 87 sample countries over the period 1970–2004. It tests the hypothesis that primary and secondary education is more suitable for imitation whereas tertiary education is more appropriate for innovation. The results show that the growth enhancing effects of higher education increase with proximity to the technology frontier only for high and medium income countries.     

Marketing challenges and organic farming in India—Does farm size matter?

The growing health consciousness among the consumer and increasing awareness about organic food has led numerous opportunities for organic producers. Along with opportunities, there also arise challenges; thus, the main purpose of this study is to explore the marketing challenges faced by the organic and conventional farmers in India. The study also aims to examine the differential association of the marketing challenges on various farm sizes. The sample comprised 400 Indian farmers including both conventional and organic producers. A sequential form of mixed‐method design, that is, qualitative–quantitative, was applied. In the first phase, an exploratory study was convened to find out the marketing challenges among organic and conventional farmers. In the second (quantitative) phase, binomial and multinomial logistics regression was applied to ascertain the differential impact of the marketing challenges on the type of farming and different farm sizes. The results of the qualitative analysis revealed six major marketing challenges faced by the farmers, namely, lack of warehousing facility, lack of price information, inadequate demand for crop, costly transportation, market price variations, and lack of government support. The results suggest there are significant differences in the marketing challenges faced by the conventional and organic farmers across farm sizes. This study is among the few to examine the marketing challenges of organic and conventional farmers in a developing country such as India. The findings will help different stakeholders to frame policies and build strategies to promote organic farming, which will lead to sustainable and responsible consumption in India.     

Two-stage point estimation with a shrinkage stopping rule

Consider the problem of estimating a mean vector in ap-variate normal distribution under two-stage sequential sampling schemes. The paper proposes a stopping rule motivated by the James-Stein shrinkage estimator, and shows that the stopping rule and the corresponding shrinkage estimator asymptotically dominate the usual two-stage procedure under a sequence of local alternatives forp3. Also the results of Monte Carlo simulation for average sample sizes and risks of estimators are stated.
