O imposto territorial rural e os municípios: o impacto nas receitas municipais e a renúncia fiscal

O artigo reúne uma análise do impacto da arrecadação do Imposto Territorial Rural no período de 1995 a 1997 nos municípios paulistas de Bragança Paulista, Franca e Porto Ferreira frente à composição das receitas municipais. A análise é realizada com base nas legislações do imposto vigentes no período e realiza comparações de arrecadação e projeções tendo como referência os valores da terra nua arbitrados pela Secretaria da Receita Federal (SRF) e pesquisados pelo Instituto de Economia Agrícola da Secretaria de Estado dos Negócios da Agricultura e Abastecimento de São Paulo. Os resultados da pesquisa indicam percentuais de evasão fiscal que atingiram de 18% a 52% e inadimplência de até 31% e esse perfil de evasão se acentua quando a partir de 1996 a SRF deixa de estabelecer o valor da terra nua mínimo (VTNm) e passa a tomar como referência apenas os valores declarados pelo contribuinte.

Quantification of water in ethanol using a photothermal transparent transducer

Ethanol with added water may be found during the process of assessing its physical and chemical properties. This addition can damage automotive vehicle engines and also may contribute to tax evasion. The present contribution describes a method based on a photothermal transparent transducer to determine the water content in ethanol. A chamber with a window of lithium tantalate coated with a thin layer of indium tin oxide was used, and a 1450-nm laser diode was employed as the excitation source. The results indicated a nearly linear response of the apparatus, as a function of the water content in water/ethanol solutions ranging from 0 to 100 (vol.%). The results for the dependency of the photothermal signal on the laser power and chopping frequency suggested that reliable results can be obtained using laser power and chopping rates above 100 mW and 10 Hz, respectively. The results reported here may be useful in the development of an alternative method that can provide real-time data on the water concentration in ethanol in a rapid, portable and unambiguous way, and that can be easily used in laboratory analyses or in gas stations. © 2013 Elsevier B.V.

Global financial rulemaking and small economies

This paper addresses some unintended consequences of global financial regulation and international tax evasion prevention and their impact on small economies. It explores how failure to recognize countries’ differing access to finance and varying costs of funding as well as the high costs of complying with financial regulations may overlook some unintended consequences, especially on smaller island countries Then, it discusses the global financial architecture and governance of standard setting bodies and the actions taken to improve representation and legitimacy and remediate some of the unintended deleterious effects on emerging markets and developing economies (EMDEs). Improving governance is ever more urgent at a time when financing the post-2015 agenda will require mobilization of both public and private funds at the national, regional and global levels.

Fiscal Panorama of Latin America and the Caribbean 2016: Public finances and the challenge of reconciling austerity with growth and equality

Latin America’s fiscal accounts deteriorated slightly during 2015, registering an average deficit of 3.0% of GDP and average gross public debt of 34.7% of GDP. Of the 19 countries considered, the fiscal deficit and public debt as a share of GDP both increased in 11. The region started to build up public debt, most of it domestic, after the 2008 international financial crisis to meet the growing financing needs resulting from the worsening growth situation.

From cigarette smuggling to illicit tobacco trade

Background Tax policy is considered the most effective strategy to reduce tobacco consumption and prevalence. Tax avoidance and tax evasion therefore undermine the effectiveness of tax policies and result in less revenue for governments, cheaper prices for smokers and increased tobacco use. Tobacco smuggling and illicit tobacco trade have probably always existed, since tobacco's introduction as a valuable product from the New World, but the nature of the trade has changed. Methods This article clarifies definitions, reviews the key issues related to illicit trade, describes the different ways taxes are circumvented and looks at the size of the problem, its changing nature and its causes. The difficulties of data collection and research are discussed. Finally, we look at the policy options to combat illicit trade and the negotiations for a WHO Framework Convention on Tobacco Control (FCTC) protocol on illicit tobacco trade. Results Twenty years ago the main type of illicit trade was large-scale cigarette smuggling of well known cigarette brands. A change occurred as some major international tobacco companies in Europe and the Americas reviewed their export practices due to tax regulations, investigations and lawsuits by the authorities. Other types of illicit trade emerged such as illegal manufacturing, including counterfeiting and the emergence of new cigarette brands, produced in a rather open manner at well known locations, which are only or mainly intended for the illegal market of another country. Conclusions The global scope and multifaceted nature of the illicit tobacco trade requires a coordinated international response, so a strong protocol to the FCTC is essential. The illicit tobacco trade is a global problem which needs a global solution.

L’elusione fiscale nell’IVA e l’antielusione nell’esperienza comunitaria e nazionale in Europa

La ricerca oggetto della tesi riguarda la disamina delle esperienze comunitarie e nazionali in Europa in materia di elusione IVA ed antielusione IVA, al fine di esaminare le utilizzabili esperienze in materia per la Cina che dovrebbe iniziare a prendere le giuste azioni per fronteggiare il problema della crescente diffusione dei fenomeni dell’elusione IVA, in particolare nel contesto della riforma perdurante dell’IVA cinese verso il modello moderno. A questo fine, prima la tesi ha analizzato dettagliatamente le seguenti principali questioni sulla base delle esperienze comunitarie e nazionali dei determinati Stati Membri dell’UE: la definizione dell’elusione fiscale generale (a tale proposito, più rilevanti le differenze tra elusione fiscale ed altri relativi concetti come risparmio d’imposta, evasione fiscale e simulazione e la relazione intrinseca tra elusione fiscale ed altri relativi concetti come frode alla legge ed abuso del diritto), la definizione dell’elusione IVA (a tale proposito, più rilevanti gli aspetti di particolare interesse ai fini della definizione dell’elusione IVA), i principi e metodologie dell’elusione IVA, le applicazioni delle varie misure antielusive rivolte all’elusione IVA nell’ordinamento comunitario e negli ordinamenti interni degli alcuni principali Stati Membri dell’UE (a tale proposito, più rilevanti l’applicazone del principio Halifax, quale norma antielusiva generale basata sul principio di divieto dell’abuso del diritto, e la considerazione delle altre soluzioni antielusive applicabili nell’IVA, comprese correzioni normative e clausole antielusive specifiche), gli effetti dell’antielusione IVA e i limiti entro cui l’autorità impositiva può esercitare l’antielusione IVA per la tutela degli interessi legittimi dei soggetti passivi come certezza giuridica ed autonomia contrattuale. Poi, la tesi ha avanzato le proposte relative al perfezionamento delle soluzioni antielusive IVA nell’ordinamento tributario cinese, dopo presentati i principali regimi attuali dell’IVA cinese e analizzate le situazioni attuali realtive all’elusione IVA e all’antielusione IVA nel sistema fiscale cinese.

Il diritto alla detrazione e le frodi Iva

Il presente lavoro parte dalla constatazione che l’Imposta sul valore aggiunto è stata introdotta con lo scopo specifico di tassare il consumo in modo uniforme a livello europeo. La globalizzazione dell’economia con l’abolizione delle frontiere ha tuttavia favorito la nascita non solo di un mercato unico europeo, ma anche di “un mercato unico delle frodi”. L’esistenza di abusi e frodi in ambito Iva risulta doppiamente dannosa per l’Unione europea: tali condotte incidono quantitativamente sull'ammontare delle risorse proprie dell’Unione e sulle entrate fiscali dei singoli Stati membri nonché violano il principio di concorrenza e producono distorsioni nel mercato unico. È in questo contesto che intervengono i giudici nazionali e la Corte di Giustizia, al fine di porre un freno a tali fenomeni patologici. Quest’ultima, chiamata a far rispettare il diritto comunitario, ha sviluppato una misura antifrode e antiabuso consistente nel diniego del diritto alla detrazione qualora lo stesso venga invocato dal soggetto passivo abusivamente o fraudolentemente. Vedremo però che il problema non può essere facilmente ridotto a formule operative: al di là dello schema, fin troppo scontato, dell’operatore apertamente disonesto e degli operatori con esso dichiaratamente correi, rimane il territorio grigio dei soggetti coinvolti, qualche volta inconsapevolmente qualche volta consapevolmente, ma senza concreta partecipazione nella frode da altri orchestrata. Permane a questo punto la domanda se sia coerente - in un sistema impositivo che privilegia i profili oggettivi, prescindendo, salvo gli aspetti sanzionatori, da quelli soggettivi- negare il diritto alla detrazione Iva per asserita consapevolezza di comportamenti fraudolenti altrui o se non vi siano regole più adatte al fine di porre un freno alle frodi e dunque più conformi al principio di proporzionalità.

Social Welfare and Behavioral Public Policies

In this work I discuss several key aspects of welfare economics and policy analysis and I propose two original contributions to the growing field of behavioral public policymaking. After providing a historical perspective of welfare economics and an overview of policy analysis processes in the introductory chapter, in chapter 2 I discuss a debated issue of policymaking, the choice of the social welfare function. I contribute to this debate by proposing an original methodological contribution based on the analysis of the quantitative relationship among different social welfare functional forms commonly used by policy analysts. In chapter 3 I then discuss a behavioral policy to contrast indirect tax evasion based on the use of lotteries. I show that the predictions of my model based on non-expected utility are consistent with observed, and so far unexplained, empirical evidence of the policy success. Finally, in chapter 4 I investigate by mean of a laboratory experiment the effects of social influence on the individual likelihood to engage in altruistic punishment. I show that bystanders’ decision to engage in punishment is influenced by the punishment behavior of their peers and I suggest ways to enact behavioral policies that exploit this finding.

Delinquenz als soziales Handeln. Eine erweiterte Modellierung und empirische Überprüfung

Im vorliegenden Beitrag wird aus Perspektive der strukturell-individualistischen Handlungstheorie versucht, kriminelles Handeln als soziales Handeln zu modellieren. Die subjektiv rationale Entscheidung für oder gegen delinquentes Handeln erfolgt in Abhängigkeit von Restriktionen, Gelegenheiten, Assoziationen sowie von normativen Überzeugungen und moralischen Bewertungen von Straftaten. Die empirische Anwendung mithilfe einer Bevölkerungsumfrage in Bern liefert für intendierte Straftaten wie Ladendiebstahl, Schwarzfahren, Versicherungsbetrug und Steuerhinterziehung theoriekonsistente Ergebnisse.

More Is Not Always Better: An Experimental Individual-Level Validation of the Randomized Response Technique and the Crosswise Model

Social desirability and the fear of sanctions can deter survey respondents from responding truthfully to sensitive questions. Self-reports on norm breaking behavior such as shoplifting, non-voting, or tax evasion may therefore be subject to considerable misreporting. To mitigate such misreporting, various indirect techniques for asking sensitive questions, such as the randomized response technique (RRT), have been proposed in the literature. In our study, we evaluate the viability of several variants of the RRT, including the recently proposed crosswise-model RRT, by comparing respondents’ self-reports on cheating in dice games to actual cheating behavior, thereby distinguishing between false negatives (underreporting) and false positives (overreporting). The study has been implemented as an online survey on Amazon Mechanical Turk (N = 6,505). Our results indicate that the forced-response RRT and the unrelated-question RRT, as implemented in our survey, fail to reduce the level of misreporting compared to conventional direct questioning. For the crosswise-model RRT, we do observe a reduction of false negatives (that is, an increase in the proportion of cheaters who admit having cheated). At the same time, however, there is an increase in false positives (that is, an increase in non-cheaters who falsely admit having cheated). Overall, our findings suggest that none of the implemented sensitive questions techniques substantially outperforms direct questioning. Furthermore, our study demonstrates the importance of distinguishing false negatives and false positives when evaluating the validity of sensitive question techniques.

Smuggling and import duties in Myanmar

This paper examines the effects of import duties on smuggling in Myanmar. Following Fisman and Wei (2004), the reporting discrepancies between Myanmar’s imports records and corresponding exports recorded by trading partners are regarded as indicative of smuggling. The paper studies whether reporting discrepancies differ across trading partners as well as across time. Our main findings are first, that the hike in import duties in June 2004 helped to widen the reporting discrepancies, which suggests smuggling for tax evasion purposes and second, that reporting discrepancies differ considerably across trading partners: land borders appear to be particularly attractive venues for smugglers.

Agglomeration effects of informal sector: evidence from Cambodia

The presence of a large informal sector in developing economies poses the question of whether informal activity produces agglomeration externalities. This paper uses data on all the nonfarm establishments and enterprises in Cambodia to estimate the impact of informal agglomeration on the regional economic performance of formal and informal firms. We develop a Bayesian approach for a spatial autoregressive model with an endogenous explanatory variable to address endogeneity and spatial dependence. We find a significantly positive effect of informal agglomeration, where informal firms gain more strongly than formal firms. Calculating the spatial marginal effects of increased agglomeration, we demonstrate that more accessible regions are more likely than less accessible regions to benefit strongly from informal agglomeration.
