La presente investigación examina la existencia de memoria de largo plazo por medio del cálculo del coeficiente de Hurst y Hurst ajustado, y del análisis de características de estructuras caóticas en la serie del mercado bursátil de Chile, específicamente a través del Índice de Precios Selectivo de Acciones.

Se desarrolló un breve análisis del mercado, según la metodología de Box y Jenkings. La validez de los resultados se realizó por medio de la prueba propuesta por Brock, Dechert y Scheinkman. En segundo lugar, se procedió a analizar la dinámica y patrones del índice y de su rendimiento, para observar si existía evidencia de memoria de largo plazo.

Los resultados demuestran la presencia de esta memoria en el mercado bursátil chileno, determinado a través del índice accionario en dos escalas, diaria y trimestral, lo que además corrobora resultados obtenidos por otros autores, confirmando el uso de la metodología de Rango Re-escaldo para la identificación y determinación de memoria de largo plazo en una serie temporal.

Este estudio permitirá a futuros investigadores realizar análisis similares en otros mercados, aportando un nuevo enfoque al analizar la memoria de la largo plazo y los factores que inciden en ella.

This research examined the existence of long-term memory by calculating the coefficient of Hurst and Hurst set, and the analysis of characteristics of chaotic structures in the series of stock market of Chile, specifically through the Selective Price Index Shares.

A brief analysis of the market was developed, according to Box and Jenkins methodology. The validity of the results was performed by means of the test proposed by Brock, Dechert and Scheinkman. Secondly, we proceeded to analyze the dynamics and patterns of the index and its performance, to see if there was evidence of long-term memory.

The results demonstrate the presence of long-term memory in the Chilean stock market, determined by stock index in two scales, daily and quarterly, which also corroborates results obtained by other authors, confirming the use of the methodology Range Re-scalded for the identification and determination of long-term memory in a time series.

This study will allow future researchers to perform similar analyzes in other markets, providing a new approach when analyzing the long-term memory and the factors that affect it.

The aim of the study is to review the extant literature on International Public Sector Accounting Standards (IPSAS) adoption in emerging economies (EEs) and low-income countries (LICs) (“what do we know?”), and to propose an agenda for future research (“what do we need to know?”).

An analytical framework that builds on diffusion theory is developed. The authors follow the “PRISMA Flow Diagram” to reduce a total of 427 articles from four databases to a final sample of 41 articles. These studies are examined, aided by the analytical framework.

The authors find that IPSASs are a relevant issue for EEs/LICs. Overall, existing research is often explorative. The authors discover that the majority of articles rely on secondary data collection. While two-thirds of the studies perform a content analysis of pre-existing material, about one-fifth of the articles each collect primary data through means of interviews and questionnaires. The findings offer a holistic understanding of where and at what stages IPSAS reforms stand in EEs/LICs, and what factors influence the progression of reforms to the next stage of diffusion.

The authors outline a number of avenues for further research after discussing the dominating trends and structuring the literature based on our analytical framework. These stem from looking at the blank spots and an identified need to contextualise IPSASs adoption in EEs/LICs.

This study aims to fill the research gap regarding the usability of group reporting information in the central government. It answers the question of how the consolidated information should be formed to benefit the real needs of governmental information users.

The empirical research is based on a survey and interviews among key internal preparers and users in the central government sector in the case country, Finland.

Results show that the private sector approach regarding consolidation is not appropriately transferable to the central government sector. The key stakeholders identified several economic and financial reporting needs that exceed what formal Consolidated Financial Statement (CFS) can offer. Consolidation is needed but not according to the extensive full control approach, but rather following the budgetary approach consolidating units of the legal person of the government, and further using the partial control approach for consolidating by discretion essential special purpose SOEs.

Respondents and interviewees represented governmental internal organisations, free experts, auditors and financial managers from the group entities. Politicians and citizens were not directly represented.

Research gives applicable insights into central governments planning and developing group reporting for information needs in a favourable cost-benefit ratio. Findings benefit the development of EU's EPSAS (European Public Sector Accounting Standards) project which is still incomplete.

Research recommends governments to make a thorough analysis before deciding on a new financial reporting system. A critical analysis prevents governments to waste money and resources on a reporting system not fulfilling the real needs of information users.

The value of this research is that the private sector approach in consolidation was not taken as granted. This study investigated critically and empirically the real need for consolidated information serving steering and overseeing purposes of the government's group entities.

Considering the increased financial responsibility of local government (LG), the impact of global crises and the growing adoption of accrual accounting and common standards such as IPSAS, this work focuses on financial indicators for LGs. It explores whether the literature on financial indicators has grown, investigates whether there is any consensus on which indicators to use for assessing LG's financial condition, develops a critical reading of the literature and offers suggestions for future research and policy agendas.

A structured literature review was carried out for publications in English about LG financial indicators.

Results reveal that the number of publications dealing with financial indicators has increased over the past ten years. However, rather than focusing on a set of common indicators, the literature reports a plethora of different ones used for four main purposes: transparency and accountability compliance, performance monitoring and benchmarking, assessing LG's financial health and helping deal with exogenous crises. There is no evidence of convergence towards a common set of indicators, even though liquidity and solvency are the most popular dimensions explored by scholars.

Findings highlight the challenges in converging on financial indicators, yet no claim can be made beyond the reviewed material.

Results provide legislators, public managers, investors and rating agencies with insights about trends in financial indicators, their benefits and limitations.

The article focuses on a less popular aspect of recent financial management reforms for local administration, that is the growing fragmentation in LG indicators, accentuated by the need for common assessment tools during unprecedented widespread crises across countries and sectors.

Within the stream of research on public sector accounting standards, heritage asset accounting represents a difficult and challenging issue. This paper intends to join the debate on heritage reporting by carrying out a critical review of the Consultation Paper (CP) “Financial Reporting for Heritage in the Public Sector” issued by the International Public Sector Accounting Standards Board (IPSASB) in order to highlight its strengths and weaknesses and to make recommendations.

To this end, the current study adopts document analysis as a qualitative research method by referring to Italy as a typical and critical case study. Moreover, the authors actively took part in the Italian working group on heritage assets reporting, so they are well-informed people about the Italian point of view as well as the broad discussion underpinning the Italian response.

Evidence demonstrates that, although the proposals included in the CP represent a new step towards an organic regulation of heritage asset reporting, if these preliminary views are confronted with the reality of an emblematic context, as in the Italian case, much room for improvement remains regarding the definition, recognition, measurement and disclosure of such assets.

The originality of the paper lies in its contribution to overcoming the current controversial aspects of heritage assets reporting and the issuing of an accounting standard. In doing so, the authors also attempt to answer the call made by Anessi-Pessina et al. (2019) to investigate in detail an individual country experience to better understand the state of the art in national and international accounting standards on heritage assets.

This study aims to critically analyse the Law 9 January 2019, n. 3, on “Measures to fight crimes against the public administration and on the transparency of political parties and movements” (so-called bribe-destroyer law).

This paper draws on reports, legal scholarship and other open-source data to examine a legislative innovation for the corruption in Italy in relation to the general guarantees of the trial process and with the controversial paradigm of the national perception index of bribery.

The Italian legislative initiative that will be examined is innovative in nature and goes beyond the constitutional and conventional principles on procedural guarantees. The new initiative needs to be integrated into the international and European action against bribery that targets criminal proceeds, and at the same time, be anchored in respect for human rights during the process.

The new initiative needs to be integrated into the international and European action against bribery that targets criminal proceeds, and at the same time, be anchored in respect for human rights during the process.

Despite the aggressiveness and lofty proclamations by those who aspire to fight corruption from the highest levels, the goal of rehabilitating Italy from one of the seven “deadly sins” that delay economic growth still seems far off.

In the absence of public ethics, the increase in criminalisation does not seem sufficient on its own to guarantee the containment of the phenomenon.

This study examines the strengths and weaknesses of the important new law, its compatibility with human rights standards and its relationship to international standards of anti-bribery policies. The aggressive legislation critically relies on the pervasive and persistent lack of perception of corruption as a crime. In the confiscation (and now also reparation) of equivalent that normally addresses assets accumulated in a lawful manner, the periculum is even presumed in re ipsa and the classical aims of caution undergo a total torsion revealing an authoritarian face that takes on the meaning of anticipating further sanctioning contents. Finally, the presence of many levels of sanctioning in relation to the same fact poses serious problems of violation of the ne bis in idem rule.

The purpose of this polyphonic paper is to report on interdisciplinary discussions on the state-of-the-art and future of public sector accounting research (PSAR). The authors hope to enliven the debates of the past and future developments in terms of context, themes, theories, methods and impacts in the field of PSAR by the exchanges they include here.

This polyphonic paper adopts an interdisciplinary approach. It brings into conversation ideas, views and approaches of several scholars on the actual and future developments of PSAR in various contexts, and explores potential implications.

This paper has brought together scholars from a plurality of disciplines, research methods and geographical areas, showing at the same time several points of convergence on important future themes (such as accounting as a mean for public, accounting, hybridity and value pluralism) and enabling conditions (accounting capabilities, profession and digitalisation) for PSA scholarship and practice, and the richness of looking at them from a plurality of perspectives.

Exploring these past and future developments opens up the potential for interesting theoretical insights. A much greater theoretical and practical reconsideration of PSAR will be fostered by the exchanges included here.

In setting out a future research agenda, this paper fosters theoretical and methodological pluralism in the interdisciplinary research community interested in PSAR in various contexts. The discussion perspectives presented in this paper constitute not only a basis for further research in this relevant accounting area on the role, status and developments of PSAR but also creative potential for practitioners to be more reflective on their practices and also intended and united outcomes of such practices.
