Ítem Solo Metadatos Benford's law for integrity tests of high-volume databases: a case study of internal audit in a state-owned enterprise(Universidad ESAN. ESAN Ediciones, 2022-07-08) Morales, Héctor Rubén; Porporato, Marcela; Epelbaum, NicolasPurpose: The technical feasibility of using Benford's law to assist internal auditors in reviewing the integrity of high-volume data sets is analysed. This study explores whether Benford's distribution applies to the set of numbers represented by the quantity of records (size) that comprise the different tables that make up a state-owned enterprise's (SOE) enterprise resource planning (ERP) relational database. The use of Benford's law streamlines the search for possible abnormalities within the ERP system's data set, increasing the ability of the internal audit functions (IAFs) to detect anomalies within the database. In the SOEs of emerging economies, where groups compete for power and resources, internal auditors are better off employing analytical tests to discharge their duties without getting involved in power struggles. Design/methodology/approach: Records of eight databases of an SOE in Argentina are used to analyse the number of records of each table in periods of three to 12 years. The case develops step-by-step Benford's law application to test each ERP module records using Chi-squared (χ²) and mean absolute deviation (MAD) goodness-of-fit tests. Findings: Benford's law is an adequate tool for performing integrity tests of high-volume databases. A minimum of 350 tables within each database are required for the MAD test to be effective; this threshold is higher than the 67 reported by earlier researches. Robust results are obtained for the complete ERP system and for large modules; modules with less than 350 tables show low conformity with Benford's law. Research limitations/implications: This study is not about detecting fraud; it aims to help internal auditors red flag databases that will need further attention, making the most out of available limited resources in SOEs. The contribution is a simple, cheap and useful quantitative tool that can be employed by internal auditors in emerging economies to perform the first scan of the data contained in relational databases. Practical implications: This paper provides a tool to test whether large amounts of data behave as expected, and if not, they can be pinpointed for future investigation. It offers tests and explanations on the tool's application so that internal auditors of SOEs in emerging economies can use it, particularly those that face divergent expectations from antagonist powerful interest groups. Originality/value: This study demonstrates that even in the context of limited information technology tools available for internal auditors, there are simple and inexpensive tests to review the integrity of high-volume databases. It also extends the literature on high-volume database integrity tests and our knowledge of the IAF in Civil law countries, particularly emerging economies in Latin America.Ítem Solo Metadatos Reassessing the feasibility of adopting dollarization in Latin America(Universidad ESAN. ESAN Ediciones, 2022-07-08) Padilla, LeónPurpose: This paper analyses the possibility of Latin America's (LA) major economies adopting dollarization, considering that in the last decade macroeconomic instability has once again challenged the ability of certain economies to properly manage their own currency. Design/methodology/approach: To determine the feasibility of adopting the US dollar as official currency, the author uses the framework of optimum currency area (OCA) theory, since, in fact, dollarization is an incomplete monetary union. The author uses a structural vector autoregressive (SVAR) model to identify what type of structural shock — country-specific, regional or global — prevails in LA economies. For this purpose, the US output is used to represent the global output and determine how the shocks of the US influence the output trajectory of each LA nation. The higher the influence of the US product, the lower the costs of adopting the US dollar. Findings: The results of the variance decomposition show that the influence of the US shocks in the gross domestic product (GDP) trajectory of LA countries has significantly decreased over the last two decades, even in the currently dollarized economies. The estimates for Venezuela and Argentina show that the importance of US shocks in the trajectory of their GDP is low. Therefore, the cost of adopting the US dollar as the official currency would be high. Originality/value: In view of hyperinflation and macroeconomic imbalances in certain LA nations, the dollarization debate has resurfaced in recent years. However, the literature that empirically evaluates the feasibility of adopting dollarization as a monetary system under current economic conditions is limited.Ítem Solo Metadatos Integración económica en América Latina: la visión teórica de la CEPAL confrontada con la evolución del proyecto en la región(Universidad ESAN. ESAN Ediciones, 2011-12-30) Vázquez López, RaúlThis article tracks the main ECLAC ideas over the economic integration in Latin American underlying the change of the ideological background of ECLAC towards an orthodox sense during the nineties. When comparing those ideas with the evolution of intraregional trade in recent years, empirical evidence shows that elements that have historically hindered the projected progress are still present but in more complex forms related to the current dynamics of the international economy. In particular, the implicit management of a partial integration by transnational companies has resulted in unequal relationships between countries and in a wider use from the mentioned process by the strongest economies. The article ends, then, seeking to revitalize the pioneer ideas of ECLAC and proposes guidelines for the construction of an alternative integrationist project that supports the need of exceeding the purely commercial aspects of integration.Ítem Solo Metadatos Obstáculos al desarrollo de las pequeñas medianas empresas en América Latina(Universidad ESAN. ESAN Ediciones, 2006-06-30) Zevallos V., EmilioThis document reports progress made in compared research about the environment, barriers and prospects facing small and intermediate size companies in eight Latin American countries, although only six are presented in this paper, namely Argentina, Colombia, Costa Rica, Chile, El Salvador and Panama. The first section briefly presents each country’s business environment in terms of prevailing concepts, the overall business universe and its trouble spots. It also aims at establishing a general typology of companies. The second section reviews the study’s methodology while the third chapter deals with the elements for doing business in each country (this paper deals only with the financing, human resources and technology components). Finally, it presents some reflections about the condition of small and intermediate companies and some guidelines for public policy actions.Ítem Solo Metadatos Latinoamérica y la cultura en el siglo XXI(Universidad ESAN. ESAN Ediciones, 2002-06-30) Giesecke Sara Lafosse, MargaritaThis study deals with Latin American culture from the perspective of history and as an essential theme to understand the complexity of the problem of underdevelopment. It examines what is meant by culture, traces the history of the formation of Latin American culture and points out the role that this should correspond to overcome underdevelopment in the context of a globalized world. He argues that communication democracy and education are the alternatives for the forging of cultural identities capable of negotiating with globalization.
