Abstract

Purpose

The purpose of this paper is to estimate the Tanzanian shadow economy (SE) from 2003 to 2015 and test the statistical relationships between the SE and its potential causes and indicators.

Design/methodology/approach

The econometric analysis is based on a multiple indicators multiple causes (MIMIC) model. To calibrate the SE from the estimates, the authors adopt the value of 55.4 percentage of the SE to official GDP from the literature for the base year 2005.

Findings

The SE ranges from 52 to 61 per cent of official GDP and slightly decreases from 2013 to 2015. Increase in inflation, unemployment and government spending were the main drivers of the SE dynamics.

Research limitations/implications

Given the challenges facing estimation of the SE (e.g. small sample size, exogenous estimate to calibrate the model, meaning of the latent variable), quantification of SE should be considered to be rough measures.

Practical implications

To lower the size of the SE, the government needs to keep inflation and unemployment stable over time, to reduce government spending because it creates pressure on tax collection due to the limited tax base.

Originality/value

This is the first study specifically focused on Tanzanian SE based on the MIMIC approach. Existing estimates of Tanzanian SE are calculated by monetary models or apply a common MIMIC specification to the worldwide context.

Abstract

Purpose

This paper contributes to the literature concerning the Nigerian informal economy (IE) by estimating its size from 1991 to 2017 and identifying the major causes.

Design/methodology/approach

A structural equation approach in the form of the multiple indicators multiple causes (MIMIC) method is used to estimate the size of the Nigerian IE.

Findings

The results indicate that vulnerable employment and urban population as a percentage of the total population are the main drivers of the IE in Nigeria. The IE in Nigeria ranges from 38.83% to 57.55% of gross domestic product (GDP).

Research limitations/implications

As a result of the empirical challenges in the estimation of the IE, the estimates of Nigeria's IE are considered to be rough estimates.

Originality/value

The authors calibrated the MIMIC model with the official estimate of the informal sector published by the Nigerian National Bureau of Statistics (NBS). This was an attempt to combine the national accounting approach, to estimate the size of IE, with the MIMIC approach, and to estimate the trend of informality.

Abstract

Purpose

The goal of this paper is twofold: to estimate the unrecorded economy (UE) of Turkey over the period 1987‐2007 using a revised version of the currency demand approach, and to analyze the relationship between the UE and recorded GDP.

Design/methodology/approach

The paper proposes to measure the UE using the autoregressive distributed lag (ARDL) approach to cointegration analysis. Toda‐Yamamoto causality tests are also conducted to identify the relationship between unrecorded and recorded GDP.

Findings

This research provides fresh evidence of the size of the UE relative to the recorded GDP in Turkey, which ranges from 10.7 percent to 18.9 percent over the estimation period. Moreover, empirical evidence concretely suggests that causality runs from the recorded GDP to the UE. However, there exists a mild reverse causality.

Research limitations/implications

Measures of the UE, and particularly those based on monetary approaches, have been criticized on several counts, including their lack of robustness and weak theoretical foundations (e.g. the velocity of money in the recorded economy and in the UE is the same).

Practical implications

This analysis suggests that the UE is pro‐cyclical with respect to the recorded GDP. It suggests that the phenomenon of the UE is more dangerous when the economy is in an expensive phase. Hence, during a positive business cycle, it is clearly desirable for the government that the anti‐UE controls should be more effective.

Originality/value

The ARDL approach to estimating the size of the UE eliminates the criticism of the previous currency demand estimations, which were based on partial adjustment models. Therefore, the paper's econometric selected cointegration methodology and causality test is an improvement over the existing studies.

Abstract

Purpose

This study aims to investigate the effects of open innovation (OI) and big data analytics (BDA) on reflective knowledge exchange (RKE) within the context of complex collaborative networks. Specifically, it considers the relationships between sourcing knowledge from an external environment, transferring knowledge to an external environment and adopting solutions that are useful to appropriate returns from innovation.

Design/methodology/approach

This study analyzes the connection between the number of patent applications and the amount of OI, as well as the association between the number of patent applications and the use of BDA. Data from firms in the 27 European Union countries were retrieved from the Eurostat database for the period 2014–2019 and were investigated using an ordinary least squares regression analysis.

Findings

Because of its twofold lens based on both knowledge management and OI, this study sheds light on OI collaboration modes and highlights the crucial role they could play in innovation. In particular, the results suggest that OI collaboration modes have a strong effect on innovation performance, stimulating the search for RKE.

Originality/value

This study furthers a deeper understanding of RKE, which is shown to be an important mechanism that incentivizes firms to increase their efforts in the innovation process. Further, RKE supports firms in taking full advantage of the innovative knowledge they generate within their inter-organizational network.

Abstract

Purpose

This study investigates if wealth from natural resources impacts child health in developing countries.

Design/methodology/approach

The methodology includes testing the effect of rents from natural resources on under-five mortality rates using a multifactor health production model for 57 developing nations. The panel estimation procedure was applied to data covering 2002 to 2017, disaggregated by non-renewable and renewable resources and low and medium human development countries.

Findings

The results provide strong evidence that wealth from total natural resources has not been associated with reductions in under-five mortality rates. However, disaggregation of the sample countries by natural resource constituents revealed that only the wealth of non-renewable is strongly inversely associated with under-five mortality rates. Further disaggregation of countries by the low and medium human development constituents revealed a statistically insignificant negative correlation of non-renewable resources wealth and under-five mortality in the low human development countries. In contrast, the results of the medium human development countries revealed that wealth from natural resources (both non-renewable and renewable) had not been associated with any reductions in under-five mortality rates. The results also confirm that immunization levels, nutrition, private spending on health care, air quality, urban living and countries closer to the equator are other strong correlates of under-five mortality rates in low human development countries.

Social implications

The findings here have implications for the timely achievement of the United Nations Sustainable Development Goal 3 (to reduce under-five deaths to around 25 per 1,000 live births by 2030). Governments ought to ensure that incomes from the extractive sector are aligned in forms that promote and feed into improving child health wellbeing.

Originality/value

This research creates a shift from aggregate health wellbeing research agenda to investigate how specific aspects of human development can be linked to wealth from non-renewable and renewable natural resources in developing nations. It adds new knowledge and provides health and natural resources policymakers opportunities to combine their policies and synergize efforts to improve child health outcomes.

Abstract

Nel riprendere come Libero Docente le mie lezioni presso la Facoltà di Giurisprudenza dopo un lungo intervallo di anni in cui il Corso è stato impartito per Incarico, cioè a titolo ufficiale, prima nella facoltà di Scienze Politiche e poi in quella di Economia e Commercie, ritengo opportuno accennare alle vicende di questo insegnamento che ha segnato in certo modo il punto di partenza ed insieme il banco di prova del primo tentativo di sistematica scientifica della trattazione del turismo dal punto di vista economico e statistico. E mancherei ad un preciso dovere e ad un impulso spontaneo del mio animo se in questa occasione non rivolgessi un memore e devoto pensiero al mio grande ed indimenticabile maestro, Augusto Graziani, che seppe inculcarmi la passione per gli studi di economia politica: debbo anzi a lui anche lo specifico orientamento verso l'indagine turistica, perchè il primo tema che egli mi propose nelle esercitazioni di seminario degli Istituti Giuridici dell'Università di Napoli (oh magnifica palestra per noi giovanissimi studenti appena usciti dal Liceo!) fu quello della bilancia dei pagamenti internazionali con particolare riguardo alle cosidette partite «invisibili».

Abstract

Purpose

The purpose of this paper is to understand the role played by accounting in managing an early nineteenth century lunatic asylum in Palermo, Italy.

Design/methodology/approach

The paper is informed by Foucault’s studies of lunatic asylums and his work on governmentality which gave prominence to the role of statistics, the “science of the State”.

Findings

This paper identifies a number of roles played by accounting in the management of the lunatic asylum studied. Most importantly, information which formed the basis of accounting reports was used to describe, classify and give visibility and measurability to the “deviance” of the insane. It also legitimated the role played by lunatic asylums, as entrusted to them in post-Napoleonic early nineteenth century society, and was a tool to mediate with the public authorities to provide adequate resources for the institution to operate.

Research limitations/implications

This paper encourages accounting scholars to engage more widely with socio-historical research that will encompass organisations such as lunatic asylums.

Originality/value

This paper provides, for the first time, a case of accounting applied to a lunatic asylum from a socio-historical perspective.
