Barabási‐Albert and small‐world networks. In this model, the order‐disorder phase transition of the order parameter is well defined on small‐world networks. We calculate the value of the critical temperature Tc for several values of rewiring probability p of the directed small‐world network. For directed small‐world networks we obtained a second‐order phase transition for p = 0.2 and first‐order phase transition for p = 0.8. On directed Barabási‐Albert we show that phase transition do not exist for Ising model with spin S = 1, 3/2 and 2.

In this contribution, the solution of Mass-Spring-Damper Systems in the fractional context by using Caputo derivative and Orthogonal Collocation Method is investigated. For this purpose, different case studies considering constant and periodic sources are evaluated. The dimensional consistency of the model is guaranteed by introducing an auxiliary parameter. The obtained results are compared with those found by using both the analytical solution and the predictor-corrector method of Adams–Bashforth–Moulton type. The influence of the fractional order on the mechanical system is evaluated.

In the present contribution, an extension of the Orthogonal Collocation Method to solve fractional differential equations is proposed.

In general, the proposed methodology was able to solve a classical mechanical engineering problem with different characteristics.

The development of a new numerical method to solve fractional differential equations is the major contribution.

The purpose of this paper is to conduct a systematic review of the factors that shape tax morale. A large range of random explanatory variables identified in the literature as determinants of tax morale are synthesised and structured by drawing inspiration from the institutional theory.

To do this, a systematic search has been conducted using a library catalogue which provides access to more than 400 databases.

The finding is that the institutional theory provides a suitable theoretical basis to explore tax morale. Indeed, all the factors until now identified as determinants of tax morale (except the control variables/socio-demographic characteristics) can be categorised either as belonging to formal institutions or to informal institutions. The most salient factor is trust, with both vertical and horizontal trust positively related to tax morale.

The outcome is a call for a more nuanced understanding of not only the effect of formal and informal institutions on tax morale but also how formal and informal institutions interact and alter each other and, consequently, affect tax morale.

The paper seeks to encourage governments to start recognising that as low tax morale arises when a gap exists between formal and informal institutions, they need to design policy measures aimed to reduce this gap, rather than persisting with deterrence measures.

This is the first systematic review of the factors that influence tax morale using an institutionalist lens.

The aim of this paper is to evaluate whether the acceptability of different types of business- and individual-level non-compliance has different impacts on the likelihood of participation in undeclared work.

To evaluate this, data is reported on the EU27 and the UK from the special Eurobarometer survey no. 498, using a novel statistical methodology that deals with two potential sources of bias: sample selection error (avoidance to answer to the question about participation to undeclared work) and misclassification in the response variable (false statements about engagement in undeclared work).

This reveals the association between tax morale and participation in undeclared work. It shows that citizens find far more unacceptable undeclared work conducted by firms than individuals, but both are significantly associated with participation in undeclared work although the greatest effect is clearly exerted by individual-level tax morale.

This paper uses a methodology that accounts for the potential bias related to sample selection error and misclassification in the response variable of participation in undeclared work and sheds light on different components of tax morale.

The study aims at reviewing a synthesis of disclosure, transparency, and International Financial Reporting Standards (IFRS) implementation in an attempt to provide directions for future research. Prior research overwhelmingly supports that the IFRS adoption or effective implementation of IFRS will enhance high-quality financial reporting, transparency, enhance the country’s investment environment, and foreign direct investment (FDI) (Dayanandan, Donker, Ivanof, & Karahan, 2016; Gláserová, 2013; Muniandy & Ali, 2012). However, some researchers provide conflicting evidence that developing countries implementing IFRS are probably not going to encounter higher FDI inflows (Gheorghe, 2009; Lasmin, 2012). It has also been argued that the IFRS adoption decreases the management earnings in countries with high levels of financial disclosure. In general, the study indicates that the adoption of IFRS has improved the financial reporting quality. The common law countries have strong rules to protect investors, strict legal enforcement, and high levels of transparency of financial information. From the extensive structured review of literature using the Scopus database tool, the study reviewed 105 articles, and in particular, the topic-related 94 articles were analysed. All 94 articles were retrieved from a range of 59 journals. Most of the articles (77 of 94) were published 2010–2018. The top five journals based on the citations are Journal of Accounting Research (187 citations), Abacus (125 citations), European Accounting Review (107 citations), Journal of Accounting and Economics (78 citations), and Accounting and Business Research (66 citations). The most-cited authors are Daske, Hail, Leuz, and Verdi (2013); Daske and Gebhardt (2006); and Brüggemann, Hitz, and Sellhorn (2013). Surprisingly, 65 of 94 articles did not utilise the theory. In particular, four theories have been used frequently: agency theory (15), economic theory (5), signalling theory (2), and accounting theory (2). The study calls for future research on the theoretical implications and policy-related research on disclosure and transparency which may inform the local and international standard setters.

The objective of this study aims at reviewing a synthesis of the economic impact of the implementation of International Financial Reporting Standards (IFRS) in an attempt to provide directions for future research. There are significant evidences of adopting a high-quality set of harmonised accounting standards (i.e. IFRS) fosters trade and foreign direct investment (FDI), financial transparency, and comparability and reduces information asymmetries. From the extensive structured review of literature using the Scopus database tool, the study reviewed 108 articles, and in particular, the topic-related 41 articles were analysed. Seven journals contribute to 39% of the articles (The Accounting Review; European Accounting Review; International Journal of Accounting; Journal of Accounting Research; Revista Espanola de Financiacion y Contabilidad; Asian Review of Accounting; and International Journal of Economics and Management). However, most of the cited journals were Journal of Accounting Research, The Accounting Review, European Accounting Review, and International Journal of Accounting (Armstrong, Barth, Jagolinzer, & Riedl, 2010; Brüggemann, Hitz, & Sellhorn, 2013; Christensen, Lee, & Walker, 2007; Daske, Hail, Leuz, & Verdi, 2008, 2013). Most of the studies did not use any theory, and most of the articles utilised quantitative approach. The study calls for future research on the theoretical impactions on the economic impact of IFRS implementation in a country-specific study, cross-country study, and global study. Future studies should also focus on the policymaking agenda for the local and international standard setters.

The purpose of this paper is to contribute to the literature on demand-driven Keynesian growth in open economies by developing a formal model that combines Dixon and Thirlwall’s (1975) export-led growth model and Thirlwall’s (1979) balance-of-payments constrained growth model into a more general specification. Then, based on the model developed in this paper, the authors analyse more broadly some important issues concerning the net impact of currency depreciation on the short-run growth.

The authors build upon Dixon and Thirlwall’s (1975) export-led growth model and Thirlwall’s (1979) balance-of-payments constrained growth model in order to develop the theoretical framework. The authors also run numerical simulations to illustrate the net impact of devaluation on the short-run growth rate in different scenarios.

The authors demonstrate that the net impact of currency devaluation on growth can go either way, depending on some structural conditions such as the average share of imported intermediate inputs in prime costs of domestic firms and the institutional capacity of trade unions to set nominal wages through the bargaining process. The model also shows that the effectiveness of a competitive real exchange rate to promote growth is higher in countries where the share of labour in domestic income is also higher.

This paper provides a coherent formal starting-point for further theoretical developments on the interrelatedness between currency devaluation, income distribution and growth. These findings provide empirically testable hypothesis for future research.

The present study proposes an alternative formal solution for the theoretical problem of imposing a balance-of-payments constraint on the process of cumulative causation often incorporated in Kaldorian growth models. In terms of policy, the framework sheds further light on the relevance of income distribution and the labour market institutional framework for the dynamics of the exchange rate pass-through mechanism and allows us to map out related conditions under which currency devaluation can promote growth.

This article aims to propose a model to support the assessment and prioritization of risk in manufacturing processes.

The model integrates the failure modes and effects analysis (FMEA) criteria with the evaluation procedures of a new hesitant fuzzy linguistic-technique for Order of Preference by Similarity to Ideal Solution (HFL-TOPSIS) variation. A case study evaluating failure risk in a wiring harness assembly process demonstrated the model's applicability. A sensitivity analysis was performed to verify the effect of the variation in the weights assigned to the decision-makers (DMs).

The failure mode (FM) ranking was FM4 > FM9 > FM17 > FM2>FM8>FM12 > FM16 > FM19 > FM11 > FM3>FM18 > FM15 > FM13 > FM10 > FM14 > FM7 > FM1 > FM5 > FM6. These outcomes suggest that “stripping length less than specified” was the top priority among the 19 FMs evaluated. Sensitivity tests demonstrated the effect of the DMs’ weights on the ranking of FMs. A comparison with FMEA and HFL-TOPSIS demonstrates the model's greater capacity to discriminate levels of risk priority, as it identifies a total of 19 risk levels compared with 9 levels in the other approaches.

The adoption of the proposed model can drive substantial improvements in risk management practices across industries, provided that the organization has a decision-making team experienced with FMEA. Therefore, this approach promotes the continuous improvement of operations and ensures that mitigation actions effectively address critical FMs.

This is the first study to propose a risk evaluation model that accounts for DMs' hesitation in defining criteria weights through linguistic expressions. Additionally, it addresses uncertainty when assessing weights for the DMs’ opinions and considers multiple factors that affect these weights in decision-making for risk prioritization.

Many neo-Weberians adopt the state’s authority-monopolizing aim as their theoretical expectation. Through a case study of the Peruvian state and Lima’s squatter settlements, I provide evidence in support of the opposite contention: that states may unintentionally produce non-state extractive-coercive organizations. During the mid- to late-twentieth century, Lima’s population grew rapidly. Since they had few economic resources, the new urban poor requisitioned public lands and set up dozens of squatter settlements in the city’s periphery. Other researchers have identified several novel political phenomena stemming from such urban conditions. I focus here on the impact of the state. Using secondary and primary data, I examine three periods during which the state applied distinct settlement policies and one in which it did not apply a settlement policy, from 1948 to 1980. I find that when it applied each of the settlement policies, the state produced non-state political authorities – neighborhood elites – who extracted resources from squatters and tried to control neighborhood turf even against state encroachment, and that the state’s non-involvement did not produce them.

In a pandemic framework (COVID-19), this chapter explores the impact of the global economy and socio-cultures concerning three axes: recreational, tourism, and hospitality. Although we slowly see an economic revival, it is well known that this sector of study is very susceptible to being affected by the context of nations. Following restrictions and measures taken by governments around the world to reduce the number of cases of coronavirus infections, many nations closed their borders, affecting international travel and by 2020 tourism had been reduced to the near cessation of operations due to the imminent fear of this poorly studied disease, and the service sector was negatively affected. It should be added that, according to the World Tourism Organization's projections, a decrease of between 20 and 30% is forecast for 2020 compared to the previous year.
