Abstract

Importance sampling is a popular Monte Carlo method used in a variety of areas in econometrics. When the variance of the importance sampling estimator is infinite, the central limit theorem does not apply and estimates tend to be erratic even when the simulation size is large. The authors consider asymptotic trimming in such a setting. Specifically, the authors propose a bias-corrected tail-trimmed estimator such that it is consistent and has finite variance. The authors show that the proposed estimator is asymptotically normal, and has good finite-sample properties in a Monte Carlo study.

Abstract

This chapter conceptually addresses outward internationalisation of small and medium sized enterprises (SMEs) from the emerging markets (EMs) by focussing on the role of prior contract manufacturing relationships with a developed market multinational enterprise (DMNE). The internationalisation of SMEs originating from EMs is a rather under-researched area and the role of prior contract manufacturing experience specifically has not been addressed in prior studies. Based on a literature review, the authors identified four capabilities developed by EM SMEs during their contract manufacturing relationships with DMNE(s) that potentially help in later outward internationalisation. The authors incorporate some insights from dynamic capabilities theory, and develop propositions addressing the role of relational capital, human capital, manufacturing productivity capabilities and product innovation capabilities in this specific context. Despite being conceptual in nature, this chapter is one of the first to explicitly highlight the role of these specific capabilities developed during contract manufacturing relationship for outward internationalisation, setting bases for future studies to further empirically investigate them in different contexts.

Abstract

Purpose

In heterogeneously segmented markets, collaborating with product users in product innovation is important for business success. End user innovators and embedded user innovators differ in terms of their prior embeddedness in the target industry. The purpose of this study is twofold. First, the authors empirically compare these two types of user innovators in terms of their diffusion channel selection. Second, the authors analyze how the technological advances of their innovations affect this difference.

Design/methodology/approach

Using an online questionnaire survey, this study collected a sample of 237 user-generated innovations in Japan and analyzed several hypotheses using quantitative statistical approaches.

Findings

The analysis shows that embedded user innovators are more likely than end user innovators to transfer their innovations to producers rather than peers. As the technological advances of their innovations increase, end user innovators' likelihood of transferring their innovation to producers increases more significantly than that of embedded user innovators.

Originality/value

This is the first paper to investigate the difference between end user innovators and embedded user innovators with respect to their diffusion channel selection as well as the moderating role of technological advances. The findings bring new perspectives to the domains of user–producer collaboration and technology transfer.

Abstract

Purpose

The purpose of this study is to analyze the topics of COVID-19 news articles for better obtaining the relationship among and the evolution of news topics, helping to manage the infodemic from a quantified perspective.

Design/methodology/approach

To analyze COVID-19 news articles explicitly, this paper proposes a prism architecture. Based on epidemic-related news on China Daily and CNN, this paper identifies the topics of the two news agencies, elucidates the relationship between and amongst these topics, tracks topic changes as the epidemic progresses and presents the results visually and compellingly.

Findings

The analysis results show that CNN has a more concentrated distribution of topics than China Daily, with the former focusing on government-related information, and the latter on medical. Besides, the pandemic has had a big impact on CNN and China Daily's reporting preference. The evolution analysis of news topics indicates that the dynamic changes of topics have a strong relationship with the pandemic process.

Originality/value

This paper offers novel perspectives to review the topics of COVID-19 news articles and provide new understandings of news articles during the initial outbreak. The analysis results expand the scope of infodemic-related studies.

Abstract

Purpose

One of the crucial issues in the contemporary finance is the prediction of the volatility of financial assets. In this paper, the authors are interested in modelling the stochastic volatility of the MAD/EURO and MAD/USD exchange rates.

Design/methodology/approach

For this purpose, the authors have adopted Bayesian approach based on the MCMC (Monte Carlo Markov Chain) algorithm which permits to reproduce the main stylized empirical facts of the assets studied. The data used in this study are the daily historical series of MAD/EURO and MAD/USD exchange rates covering the period from February 2, 2000, to March 3, 2017, which represent 4,456 observations.

Findings

By the aid of this approach, the authors were able to estimate all the random parameters of the stochastic volatility model which permit the prediction of the future exchange rates. The authors also have simulated the histograms, the posterior densities as well as the cumulative averages of the model parameters. The predictive efficiency of the stochastic volatility model for Morocco is capable to facilitate the management of the exchange rate in more flexible exchange regime to ensure better targeting of monetary and exchange policies.

Originality/value

To the best of the authors’ knowledge, the novelty of the paper lies in the production of a tool for predicting the evolution of the Moroccan exchange rate and also the design of a tool for the monetary authorities who are today in a proactive conception of management of the rate of exchange. Cyclical policies such as monetary policy and exchange rate policy will introduce this type of modelling into the decision-making process to achieve a better stabilization of the macroeconomic and financial framework.

Abstract

Judgments and decision are central to entrepreneurship, but capturing them empirically is challenging. Shepherd and Zacharakis (1997) addressed this challenge by identifying metric conjoint analysis as an experimental method capable of capturing the decision policies of actors engaged in entrepreneurial task, creating a “window of opportunity” for entrepreneurship research. On the twentieth anniversary of this chapter, the authors reflect on the impact the ideas had on their own work and careers, while, at the same time, address the possibility that the “typical” conjoint study may have reached the end. From this platform, the authors identify unknown attributes, interactive effects, rich media, mixed methods, and sophisticated data analysis as potential pathways by which conjoint analysis can continue to advance understanding of entrepreneurship. Their conclusion is that when coupled with impactful research questions, innovative uses of conjoint analysis have an important role to play in the future of entrepreneurship research. Hence, the authors believe that Dean A. Shepherd’s and Zach Zacharakis’s bold effort will continue as a quintessential resource for those researchers who wish to tap the mind of entrepreneurs, investors, and other key actors as they traverse the journey of business venturing.

Abstract

Purpose

Social enterprises (SEs) face tensions when combining financial and social missions, and this is particularly evident in the scaling process. Although extant research mainly focuses on SEs that integrate their social and financial missions, this study aims to unpack social impact scaling strategies in differentiated hybrid organizations (DHOs) through the case of African SEs.

Design/methodology/approach

The study entails an inductive multiple case study approach based on four case SEs: work integration social enterprises (WISEs) and fair trade producer social enterprises (FTPSEs) in Uganda and Kenya. A total of 24 semi-structured interviews were collected together with multiple secondary data sources and then coded and analyzed through the rigorous Gioia et al. (2013) methodology to build a theoretical model.

Findings

The results indicate that SEs, as differentiated hybrids, implement four types of social impact scaling strategies toward beneficiaries and benefits (penetration, bundling, spreading and diversification) and unveil different dual mission tensions generated by each scaling strategy. The study also shows mutually reinforcing mechanisms named cross-bracing actions, which are paradoxical actions connected to one another for navigating tensions and ensuring dual mission during scaling.

Research limitations/implications

This study provides evidence of four strategies for scaling social impact, with associated challenges and response mechanisms based on the cross-bracing effect between social and financial missions. Thus, the research provides a clear framework (social impact scaling matrix) for investigating differentiation in hybridity at scaling and provides new directions on how SEs scale their impact, with implications for social entrepreneurship and dual mission management literature.

Practical implications

The model offers a practical tool for decision-makers in SEs, such as managers and social entrepreneurs, providing insights into what scaling pathways to implement (one or multiples) and, more importantly, the implications and possible solutions. Response mechanisms are also useful for tackling specific tensions, thereby contributing to addressing the challenges of vulnerable, marginalized and low-income individuals. The study also offers implications for policymakers, governments and other ecosystem actors such as nongovernmental organizations (NGOs) and social investors.

Originality/value

Despite the growing body of literature on scaling social impact, only a few studies have focused on differentiated hybrids, and no evidence has been provided on how they scale only the social impact (without considering commercial scaling). This study brings a new perspective to paradox theory and hybridity, showing paradoxes come into view at scaling, and documenting how from a differentiation approach to hybridity, DHOs also implemented cross-bracing actions, which are reinforcement mechanisms, thus suggesting connections and synergies among the actions in social and financial mission, where such knowledge is required to better comprehend how SEs can achieve a virtuous cycle of profits and reinvestments in social impact.

Abstract

Purpose

The purpose of this paper is to examine the trust repair efforts of top management within an organization specifically focusing on the impact of perceived organizational support and issue‐selling success. Building on the theoretical trust repair literature, the authors bridge the gap between the laboratory dyad trust repair settings and the severe organization‐wide trust repair settings.

Design/methodology/approach

The authors focus on one organizational context that experienced competency‐ and integrity‐based trust violations between managers and top management. Surveys and interviews were conducted with 32 managers to capture trust in top management, issue‐selling success rate, and perceived organizational support.

Findings

Results demonstrate that perceived organizational support is significantly and positively related to trust in top management. In contrast, issue‐selling success rate is negatively related to trust in top management above and beyond the impact of perceived organizational support.

Practical implications

Trust repair approaches should include demonstrations of organizational support of employees by showing care and concern along with engaging employees in a change process that demonstrates top management commitment to repairing trusting relationships. In addition, top management trust repair efforts should focus on providing managers with the opportunity to engage in multiple issue‐selling episodes.

Originality/value

The paper contributes to an existing research base by extending the approaches to repairing trust in organizational settings to specifically examine the impact of perceived organizational support and issue‐selling.

Abstract

Purpose

The authors probe the relationships between country institutional support for entrepreneurship and new venture survival. Specifically, the authors unpack the nuanced influences of entrepreneurs' perceived environmental uncertainty and their subsequent entrepreneurial behavioral profiles and how this particularly bolsters venture survival in contexts with underdeveloped institutions for entrepreneurship.

Design/methodology/approach

Coleman (1990) ‘bathtub’ framework is applied to develop a model and propositions surrounding how and when emerging market entrepreneur's perceptions of their countries institutional support toward entrepreneurship can ultimately enhance new venture survival.

Findings

Entrepreneurs' interpretations of regulatory, cognitive and normative institutional support for private enterprise helps them embrace uncertainties more accurately reflective of “on the ground” realities and stimulates constructive entrepreneurial behaviors. These are critical for increasing survival prospects in characteristically turbulent, emerging market contexts that typically lack reliable formal resources for cultivating nascent ventures.

Practical implications

This paper has implications for international policymakers seeking to stimulate and sustain entrepreneurial ventures in emerging markets. The authors shed light on the practical importance of understanding the social realities and interpretations of entrepreneurs in a given country relating to their actual perceptions of support for venturing—cautioning a tendency for outsiders to over-rely on aggregated econometric indices and various national ‘doing business' rankings.

Originality/value

This study is the first to create a conceptual framework on the mechanisms of how entrepreneurs in emerging economies affect new venture survival. Drawing on Coleman's bathtub (1990), the authors develop propositional arguments for a multilevel sequential framework that considers how developing economies' country institutional profiles (CIP) influence entrepreneurs' perceptions of environmental uncertainty. Subsequently, this cultivates associated entrepreneurial behavior profiles, which ultimately enhance (inhibit) venture survival rates. Further, the authors discuss the boundary conditions of this regarding how the national culture serves to moderate each of these key relationships in both positive and negative ways.
