Abstract

Purpose

In order to assess the performance of an induction generator in standalone wind power application, it is imperative that mathematical models are developed that accurately represent the system and take into account various electromagnetic influences such as skin effect. The purpose of this paper is to utilize mathematical models to study the transient and steady‐state behaviour of the self‐excited induction generator (SEIG), in one case with an aluminum rotor, in another case, with a copper rotor, under various load conditions while taking the above factor into account.

Design/methodology/approach

Mathematical models of a SEIG in the d‐q axis frame have been developed based on the generalized machine theory. A relationship between the mutual inductance and the magnetizing current of the machine has been presented. The rotor impedances have been customized to include skin effect. Using these relations, the model has been extended to include the saturation and skin effects. In order to verify the accuracy of the models, numerical and experimental investigations have been carried out on two 7.5 hp aluminum‐rotor and copper‐rotor SEIGs.

Findings

It was found that the model that takes into account the saturation and skin effects produces numerical results that closely match experimental values for both the machines.

Originality/value

This paper describes how a model of an SEIG considering saturation and skin effect has been developed and applied to aluminum‐ and copper‐rotor machines of similar power ratings to analyze their performance.

Abstract

Purpose

The financial industry offers a unique setting to study innovations. Financial innovations have fueled the growth of economies, markets and societies. The financial industry has successfully become the breeding ground for innovative services, processes, business models and technologies. This study seeks to provide a holistic view of the literature on financial innovations, synthesize the research findings and offer future directions for research in light of three market developments that are disrupting the industry and opening up a new era for the financial services industry. Disruptions from within and outside the industry offer new generations of radically innovative services. Moreover, new generations of consumers differ from previous generations in their needs and wants and look for innovative ways to handle their financial needs. Finally, significant developments related to financial innovations have emerged in Asia and developing countries.

Design/methodology/approach

This study systematically reviews the academic research literature on financial innovations in two phases. The first phase provides a quantitative review of 546 journal articles published between 1990 and 2018. In the second phase, the study synthesizes the extant research on financial innovations and maps them in five research areas: firms' introduction and adoption of FIs, financial innovation development, the outcomes of financial innovations, regulations and intellectual property, and consumers.

Findings

The analysis found that disciplines differ with regard to the employed research methodologies, the units of analysis, sources of data and the innovations they examined. A positive trend in the number of published articles during this period is observed. However, studies have primarily focused on the USA and Europe and less so on other parts of the world. The literature synthesis further identifies research gaps in the available research that highlight future research opportunities in light of the three market disruptions. The financial services industry is on the brink of a new era due to disruptions from within and outside the industry and the entrance of new generations of consumers. Moreover, the financial industry has successfully become the breeding ground for innovative services, processes and business models. Therefore, financial innovations offer promising opportunities for bridging the gap between research on product and service innovations.

Research limitations/implications

The work provides a holistic and systematic overview of extant research on financial innovations and highlights future research opportunities in light of the three disruptive market developments. It helps researchers take advantage of the opportunities in studying financial innovations while maintaining industry relevance.

Originality/value

The study is the first to review and synthesize the academic research literature on financial innovations across marketing, finance and innovation disciplines. In addition, the study highlights three primary disruptive forces in the financial industry and identifies future research directions in light of these disruptive forces.

Abstract

Purpose

The purpose of this paper is to investigate the impact of the macroeconomic condition on investment-cash flow sensitivity (ICFS) of Indian firms and examine whether the effect of macroeconomic condition on ICFS depends on the size and group affiliation of the firm.

Design/methodology/approach

An empirical investigation is conducted using a dynamic panel data model or more specifically system generalized method of moments (GMM) estimation technique.

Findings

Empirical findings postulate that the availability of cash flow influences the investment decisions which depicts that Indian manufacturing firms are internally as well as externally financially constrained. This study finds that good economic condition (period of high GDP growth rate) reduces the ICFS, although this effect is stronger for small-sized and standalone firms than the large-sized and business group affiliated firms. The authors find that macroeconomic condition has a positive and significant effect on investment decisions.

Research limitations/implications

This study has considered only the non-financial sector. The future research could explore the effect of macroeconomic condition on ICFS might be affected by firm other characteristics such as firm age and firm capital structure.

Social implications

The government should provide loan on the low rate to the small-sized firms and standalone firms because it is very difficult for these firms to finance their investment during the bad economic condition (period of low high GDP growth rate).

Originality/value

This study contributes to the existing literature by analyzing the impact of the macroeconomic condition on ICFS as well as investment decisions of the Indian manufacturing firms, which is an unexplored issue from an emerging market perspective. To the best of my knowledge, this is a first-ever study which explores the effect of macroeconomic condition on investment decisions with respect to business group affiliation and firm size.

The purpose of this study is to explore the possible impact of banking market structure on the idiosyncratic risk of financially dependent firms in China.

Abstract

Purpose

The purpose of this study is to explore the possible impact of banking market structure on the idiosyncratic risk of financially dependent firms in China.

Design/methodology/approach

The study analyzes firm-level data for China from 1999 to 2018 using a two-step dynamic panel system generalized method of moments (GMM).

Findings

The findings imply that bank competition lowers corporate risk, particularly among firms that are highly dependent on external funding for their financing needs. The findings are consistent with alternative indicators of competition, corporate risk, and financial dependence. The analysis of the transmission mechanism – the channel through which competition affects corporate risk – reveals that bank competition reduces corporate risk by curtailing financing constraints faced by firms.

Research limitations/implications

The competition-enhancing policy should consider the optimum level of bank competition for financial and economic stability. Further research is necessary to define the “desirable” or “optimum” level of bank competition.

Practical implications

In China, where the banking sector is still highly concentrated, the findings of this study call for policies aimed at encouraging healthy competition among banks. Nevertheless, such a policy must also consider the extent of bank competition that is optimal for the economy, particularly for financial and economic stability.

Originality/value

The paper provides the first evidence of the possible linkage between bank competition and corporate risk in China.

Abstract

Purpose

There is a lacuna in research work in terms of understanding how Indian IT organizations can become global brands. Benchmarking has not received much attention in marketing literature due to lack of benchmarking framework, and IT organizations are yet to make progress in benchmarking. The purpose of this paper is to examine the impact of brand strength on global branding by developing a conceptual benchmarking framework for Indian IT organizations.

Design/methodology/approach

Semi-structured in-depth interviews are conducted with thirty middle-level managers from two Indian IT organizations, two US-based global IT organizations and one UK-based leading bank, which is a customer of these IT organizations.

Findings

Results show a positive relationship between brand strength and global branding, between customer loyalty and global branding, between brand loyalty and competitive advantage and between global branding and competitive advantage. Indian IT organizations can benchmark global IT organizations to improve delivering brand promise, positioning, awareness building and authenticity toward making Indian IT organizations future ready to address the entire breadth of opportunities in the evolving world of cloud and digital.

Practical implications

This research helps managers with a brand strength-based benchmarking framework toward global branding of Indian IT organizations.

Social implications

IT is instrumental for rapid growth of Indian’s economy. India should optimally utilize its greatest wealth, its human potential, with the latent global demand in IT through building global IT brands.

Originality/value

The originality of the study lies in conducting a qualitative study on global branding of Indian IT organizations and also proposing a conceptual benchmarking framework. The study further validates the model using qualitative analysis.

Abstract

Purpose

This study aims to analyze how Indian management practices have influenced the international management research agenda. International interest in India as a business destination has been growing since the Indian policy-makers began opening up the economy in 1991. India’s continuing economic development and integration with global economy has led to a reassessment of its political, social and commercial relevance by the international community.

Design/methodology/approach

The authors choose four management disciplines and examine 40 peer-reviewed international journals for research related to India over the period 1991-2014. From the sample of 217 papers, the authors identify the trends, themes and motivations, and discuss the potential for future research.

Findings

The authors find that research on India remains flat for the 1991-2000 decade, and starts growing from 2005 onwards. Organizational behavior remains non-participative in the overall growth of research. The authors find very low levels of qualitative research, and none on endogenous phenomena that have been tested for applicability in non-Indian contexts. Marketing research remains mainly peripheral to Indian contexts. Review of highly cited papers reveals that management research on India is at an early stage, and offers fairly significant opportunities for future researchers.

Research limitations/implications

Normal limitations of sample-based literature review apply. Further, the literature search is limited to a select set of highly ranked journals.

Originality/value

Studies analyzing themes related to Indian contexts in international publications are sparse. To the best of authors’ knowledge, no study of this nature exists in literature. This study makes a primary contribution for future management researchers across the four areas by informing on the research trends, journal outlets, and the characteristics of the research agenda.
