Abstract
In this paper, we study partial identification of the distribution of treatment effects of a binary treatment for ideal randomized experiments, ideal randomized experiments with a known value of a dependence measure, and for data satisfying the selection-on-observables assumption, respectively. For ideal randomized experiments, (i) we propose nonparametric estimators of the sharp bounds on the distribution of treatment effects and construct asymptotically valid confidence sets for the distribution of treatment effects; (ii) we propose bias-corrected estimators of the sharp bounds on the distribution of treatment effects; and (iii) we investigate finite sample performances of the proposed confidence sets and the bias-corrected estimators via simulation.

Abstract
Advances in Econometrics is a series of research volumes first published in 1982 by JAI Press. The authors present an update to the history of the Advances in Econometrics series. The initial history, published in 2012 for the 30th Anniversary Volume, describes key events in the history of the series and provides information about key authors and contributors to Advances in Econometrics. The authors update the original history and discuss significant changes that have occurred since 2012. These changes include the addition of five new Senior Co-Editors, seven new AIE Fellows, an expansion of the AIE conferences throughout the United States and abroad, and the increase in the number of citations for the series from 7,473 in 2012 to over 25,000 by 2022.

Abstract
We provide a new characterization of the equality of two positive-definite matrices A and B, and we use this to propose several new computationally convenient statistical tests for the equality of two unknown positive-definite matrices. Our primary focus is on testing the information matrix equality (e.g. White, 1982, 1994). We characterize the asymptotic behavior of our new trace-determinant information matrix test statistics under the null and the alternative and investigate their finite-sample performance for a variety of models: linear regression, exponential duration, probit, and Tobit. The parametric bootstrap suggested by Horowitz (1994) delivers critical values that provide admirable level behavior, even in samples as small as n = 50. Our new tests often have better power than the parametric-bootstrap version of the traditional IMT; when they do not, they nevertheless perform respectably.

Abstract
Purpose
This paper analyses how entrepreneurs recognise and exploit entrepreneurial opportunities following a sustainable approach that respects the equilibrium among environmental, social and commercial purposes, and how their personality affects this process. The main personality traits focused in this study are narcissism, locus of control and sustainability orientation.
Design/methodology/approach
This single case study involves Essentia Dimora Rurale, a small agritourism business, located in Molise (Italy), characterised by a sustainable business model that generates value for the local environment, thus revitalising abandoned territories. Data are collected using qualitative and quantitative methods and are analysed using the Gioia methodology.
Findings
The Essentia Dimora Rurale's approach is rooted in the concept of sustainability and the development of tourism in the territory. The preservation of traditional values and the creation of a network allow the firm to prosper and survive. The personalities of the two sibling entrepreneurs fuel the process, and the authors show that each personality trait plays a different role in each phase of the firm's growth.
Research limitations/implications
From a theoretical point of view, the study contributes to entrepreneurial, sustainability and personality literature. However, using a single case study can represent a limit for the research.
Practical implications
Various practical implications are recognised concerning several stakeholders, such as the owners and the entities linked to the regional promotion and tourism sectors.
Originality/value
The novelty of the research relies on the importance of entrepreneur opportunity identification, particularly in sustainable firms. Moreover, the authors fill the literature gap investigating the impact of three personality traits in this process.

Abstract
Purpose
The purpose of this paper is to report results of a study carried out to establish the mediation effect of sustainability intention in the relationship between sustainability behavioral control and sustainable entrepreneurship.
Design/methodology/approach
This study is cross sectional and correlational. Data were collected through a questionnaire survey of 384 small businesses. Data were analyzed through correlation coefficients and linear regression using Statistical Package for Social Sciences and the Medgraph program.
Findings
The results suggest that sustainability intention partially mediates the relationship between sustainability behavioral control and sustainable entrepreneurship. Results further indicate that sustainability behavioral control and sustainability intention are significant predictors of sustainable entrepreneurship.
Originality/value
This study provides an initial empirical evidence on the mediation effect of sustainability intention in the relationship between sustainability behavioral control and sustainable entrepreneurship. To the researcher's knowledge, no study had been conducted on such an interesting topic using evidence from a developing country such as Uganda.

Abstract
Purpose
This paper reviews the literature available on sustainable entrepreneurship along with the terms used interchangeably (as the context demands) and explores the themes research have undertaken to explain the concept across multidisciplinary avenues. The purpose of this literature review is to determine the direction of research in the field of sustainable entrepreneurship. It also enables the author to find out the relevance with similar terminologies, i.e. green entrepreneurship, ecopreneurship, ecological entrepreneuship etc. Also, how various differentiating concepts under the guise of sustainable entrepreneurship contribute to the similar goals on organizational level.
Design/methodology/approach
Scopus and Web of Science databases are explored for research articles including term “sustainable entrepreneurship”. A list of 50 most cited articles is extracted from the results and analyzed for underlying themes and trends in current research. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standard is used to systematically search articles from two databases and filtering for the most relevant manuscripts.
Findings
The categorization of research articles is conducted to understand the direction of research in this field and the emphasis on specific aspects. Themes identified are further elaborated into subcategories to get to the underlying theme of the research article. The research trend implicates the shift toward practical application and evaluation along with conceptual exploration and analysis which is inherent in any field of research.
Originality/value
The literature review in primarily conducted on two most referred databases, i.e. Scopus and Web of Science, as the search for term “sustainable entrepreneurship” yeilded most results in these databases. Also the methodology adopted focused on the most cited articles in the past two decades to extract the themes and subthemes. This allows the researcher to determine the trends and gaps in the current research.

Abstract
Though logistics security only took care of trading phase in the past, many countries in the world have begun to introduce logistics security system as its coverage has been extended from production stage to delivery at the final destination. Logistics security system has become indispensable element for global corporations involved in international trading and studies on logistics security keep going on. Most of the studies, however, are focused on discussion of system, cost and influence of logistics security and few of them have been specifically dealing with substantial effectiveness thereof. This study developed the models of supply chain security activities and their outcome by means of using Balanced Scorecard (BCS) which is a well known performance indicator to identify relationship between supply chain security activities and their accomplishment. In this study we have presented 8 supply chain frameworks, human resources management, information system management, facilities/freight management, security process, crisis management capability, relationship with partners, sharing of logistics information and logistics security accomplishment, with reference to standards of C-TPAT and AEO based on WCO framework, 10 supply chain security capabilities. This study further indicates that relationship with partners has more effect on logistics security accomplishment than sharing of logistic information. Just as relationship between corporations in chain of supply and sharing of information among them are important elements in management of supply chain, relationship with partners and sharing of logistic information will have positive effect on supply chain security accomplishment and raise its effectiveness.

Abstract
Purpose
This paper explores how sustainability consciousness varies among undergraduate students at a higher education institution in the Republic of Korea. Based on the analyses of survey data, this paper aims to understand the present state and future prospect of education for sustainable development, specifically within higher education in the Republic of Korea.
Design/methodology/approach
This study involves analyzing 254 complete responses from undergraduate students at Seoul National University using confirmatory factor analysis. Subsequently, it explores how five variables (gender, grade year, type of college, prior exposure to sustainable development and prior exposure to education for sustainable development) influence the level of sustainability consciousness among these undergraduates.
Findings
The goodness-of-fit indices of the adapted sustainability consciousness questionnaire indicate a good fit. The analysis reveals a notable gender-based disparity in sustainability consciousness, with female students exhibiting higher levels than their male counterparts. Additionally, academic progression also affects sustainability consciousness; students in their first and second years show greater awareness compared to those in their third year. Furthermore, the academic discipline of respondents plays a role, as evidenced by students from the College of Education displaying higher sustainability consciousness than those from other colleges.
Originality/value
This research distinguishes itself from prior studies in two key dimensions. First, it offers an analysis of the sustainability consciousness among South Korean undergraduate students, with a particular focus on those who have experienced the COVID-19 pandemic. Second, this study endeavors to establish the validity of sustainability consciousness as a psychological construct, expanding the understanding of its implications and relevance in the context of higher education.
