Abstract:
Nonostante l'abbondanza di studi sull'innovazione sociale, il focus è solitamente rivolto alle organizzazioni senza scopo di lucro il cui obiettivo principale è raggiungere il cambiamento sociale, mentre il coinvolgimento di attori esterni, tra cui le imprese profit, nello sviluppo dell'innovazione sociale è ancora trascurato nella letteratura.Pertanto, il principale obiettivo è estendere la comprensione concettuale dell'innovazione sociale e fornire un contributo alla concettualizzazione ed agli studi sulla open social innovation.Quindi, il social open innovation viene studiato attraverso un framework concettuale, che prevede una revisione della letteratura relativa ai modelli di social innovation e di open innovation.Tant'è che il lavoro delinea l'aspetto "aperto della social innovation, evidenziando sia l'utilità del coinvolgimento di differenti attori e processi nella generazione e diffusione di idee in grado di affrontare un cambiamento sociale, che la tendenza a definire nuovi modelli di business.Per raggiungere tale obiettivo, lo studio si concentra su una revisione della letteratura senza analisi empiriche. Casi di studio o approcci quantitativi potrebbero rappresentare utili sviluppi per ulteriori ricerche.Inoltre, il lavoro si focalizza sulla social innovation prodotta da imprese profit in un contesto di collaborazione con stakeholder di varia natura, tanto da caratterizzare un'evoluzione dei modelli di business tradizionali verso un modello "hybrid.

Abstract:
En este trabajo se examina la relación entre la inclusión financiera y la pobreza monetaria de los hogares del municipio de Sincelejo, departamento de Sucre (Colombia), y se confirma la correlación entre las dos variables a través de un modelo econométrico probabilístico o de respuesta cualitativa, denominado Probit; utilizando, además, otras variables socioeconómicas que ayuden a explicar el fenómeno de la inclusión financiera. Para lograrlo se tomó información primaria mediante encuestas a 541 hogares sincelejanos sobre las variables involucradas en el análisis y, mediante el programa Eviews 7.1, se procesó la información para obtener la estimación del modelo econométrico. Los resultados confirman que este fenómeno se puede estudiar, adecuadamente, a través de un análisis de regresión binomial y que existe una relación inversa entre pobreza monetaria e inclusión financiera (medida a partir de hogares que han tenido algún tipo de servicio o producto en entidades financieras formales). Se confirma, igualmente, que el factor más relevante para incrementar las probabilidades de inclusión de los hogares son los mayores niveles de educación del jefe del hogar.

El presente trabajo analiza el impacto de la demanda efectiva sobre el nivel de ocupación en las 51 clases de actividad económica que conforman el subsector 32 de la industria manufacturera en México. Específicamente, se procura identificar las clases de actividad económica que presentan una probabilidad aceptable de potenciar el empleo por encima del promedio del subsector. Para tal efecto, se estiman tres modelos de elección discreta: uno de probabilidad lineal, un Logit y un Probit. Esto con el interés de contrastar resultados alternativos y seleccionar el modelo más idóneo para explicar la relación analítica indicada. Los resultados empíricos indican que el modelo Probit exhibe el mejor ajuste para explicar la capacidad de generar empleos.

Abstract:
Objetivou-se, neste trabalho, equacionar a qualidade inicial das sementes (Ki), utilizada no modelo de probit, para a previsão da longevidade de sementes de milho (Zea mays) e soja (Glycine max), em função do resultado dos testes iniciais de germinação e vigor. Onze lotes de sementes de diferentes cultivares de milho e de soja foram submetidos aos testes de germinação (TG), envelhecimento acelerado (TEA), frio sem solo (TF), para milho, e tetrazólio (TZ), para soja, e a testes de envelhecimento acelerado, com condições constantes do grau de umidade e da temperatura das sementes, para determinar o valor de Ki. Dados da literatura contendo resultados de testes de TEA e TF para milho e TEA e TZ para soja também foram usados nesta pesquisa. Conduziram-se análises de regressão linear simples e múltipla para equacionar: a) Ki em função de TG e TEA para milho e soja, b) TEAm (envelhecimento acelerado do milho) em função de TF; c) TEAs (envelhecimento acelerado da soja) em função de TZ. As equações obtidas foram: Ki = 0,4230 + 0,4464 TG + 0,4131 TEA TEA M = - 0,4408 + 1,214 TF TEA S = - 0,1872 + 0,9875 TZ. A equação de Ki apresentou coeficiente de determinação ajustado (r²) de 0.80 (d.p. 0.18 probit e parâmetros significantes em p < 0.01, p < 0.02 e p < 0.05, respectivamente). A equação de TEAm apresentou r² de 0.80 (d.p. 0.24 probit e parâmetros significantes em p < 0.002). A equação de TEAs apresentou r² de 0.84 (d.p. 0.18 probit e parâmetros significantes em p < 0.005). O valor de Ki pode ser equacionado em função do resultado dos testes iniciais de germinação e vigor para milho e soja (TEA ou TF para milho e TEA ou TZ para soja).

Abstract:
Utilizaram-se os modelos lineares generalizados com as funções de ligação probit e logit na avaliação da prenhez precoce, e observaram-se os efeitos na variabilidade genética e na seleção de reprodutores quando diferentes idades são adotadas na definição dessa característica. A prenhez precoce foi estudada aos 15 (PP15) e 21 meses (PP21). Correlações entre os valores genéticos preditos e a porcentagem de touros em comum, considerando 10% dos touros com maiores valores genéticos (TOP10), entre a classificação dos modelos com função de ligação logit e probit e em cada modelo entre PP15 e PP21, foram calculadas. As herdabilidades para PP15 e PP21 foram próximas entre os modelos, exceto para PP15 utilizando a função de ligação probit. Aquelas entre os modelos e a TOP/10 foram altas. Os critérios de Akaike e Bayesiano apresentaram-se semelhantes entre os modelos. As correlações entre PP15 e PP21 e a TOP10, considerando o mesmo modelo, foram de média magnitude.

Abstract:
Der vorliegende Beitrag beschreibt Methoden und stellt deren Ergebnisse vergleichend gegenüber, die in jüngster Zeit auf der Grundlage einer Statistik, der Einkommens- und Verbrauchstichprobe 2018 (EVS 2018), für den Regelbedarf ermittelt wurden. Einbezogen in die Darstellung sind die Modelle des Bundesministeriums für Arbeit und Soziales, der Parität auf der Grundlage von Sonderauswertungen der EVS 2018 durch Die Linke, von Becker/Tobsch (2020) für die Bundestagsfraktion Bündnis 90/Die Grünen, von Becker/Held (2020) für die Diakonie Deutschland sowie das Modell von Schüssler (2018; 2019). Für das Modell von Schüssler werden erstmals Resultate publiziert. Die Ergebnisse weisen mit Ausnahme des BMAS-Modells eine eher geringe Spannweite der resultierenden Euro-Beträge des „Bedarfs“ auf. Sie ist im wesentlichen durch die Wahl des Referenzbereichs (Bereich unterer Einkommen oder gesellschaftliche Mitte) sowie durch den politisch gesetzten Abstand des Regelbedarfs vom gewählten Referenzbereich bestimmt. From Standard Needs to Standard Income. Methods and Calculation Results Based on the EVS 2018 The following paper describes the methods and compares the results of recent studies carried out to determine income support, which were based on the 2018 federal statistic on income and consumer expenditures (EVS 2018). This paper examines the models of the BMAS (the German Federal Ministry of Labour and Social Affairs), of “Parität” (a german non-profit organisation) on the basis of special evaluations by the political party “Die Linke”, by Becker/Tobsch (2020) for the parliamentary group of “Bündnis 90/Die Grünen”, by Becker/Held (2020) for the “Diakonie Deutschland”, as well as the modelling by Schüssler (2018; 2019). For the first time results of Schüssler’s model are published here. The findings reveal – with the exception of the BMAS-Model – a relatively small range in the proposed level of “needs“ in Euros. This range is primarily determined by the choice of the reference range (lower household income or median income group), as well as by the politically determined gap between income support and the chosen reference range.

Abstract:
In seguito al recepimento della nuova disciplina di vigilanza prudenziale, le banche possono optare per due metodi alternativi per il calcolo dei requisiti patrimoniali minimi a fronte del rischio di credito: il metodo standardizzato, che prevede il ricorso ai rating esterni forniti da Agenzie specializzate, ed il metodo dei rating interni, basato su modelli testati internamente dalle banche. Mentre da tempo sono state implementate metodologie interne per il calcolo del rating del segmento imprese (peraltro, ancora non del tutto affidabili), sono poche le banche che hanno sviluppato una valutazione interna delle amministrazioni statali e locali e non si trova, inoltre, adeguato supporto teorico da parte della letteratura scientifica. Partendo da tale premessa, il presente lavoro di ricerca si propone di analizzare le metodologie di valutazione adottate dalle Agenzie di rating per individuare quali fattori economico-finanziari incidono in maggior misura sui sub-sovereign credit rating assegnati agli Enti Locali italiani, anche allo scopo di poter mutuare tali metodologie nei processi di valutazione del merito di credito delle banche. A tal fine, è stato applicato un modello probit ordinato multinomiale ad oltre 310 rating assegnati da Moody’s, Standard & Poor’s e Fitch Ratings ad un campione di Province e Comuni capoluogo italiani tra il 2004 e il 2008. I risultati dell’analisi aggregata consentono di confermare in parte le attese teoriche, evidenziando altresì le divergenze di valutazione tra Agenzie riscontrate in letteratura. In particolare, solo l’indicatore macro-economico rappresentativo del PIL locale pro-capite appare statisticamente significativo e di segno atteso, mentre le variabili di natura strutturale e comportamentale degli Enti sono significative solo per due Agenzie, ma non sempre rispettano il segno atteso. Contrariamente alle attese teoriche e alle evidenze empiriche emergenti in letteratura, il livello di indebitamento locale pro-capite nonché l’indicatore del fabbisogno finanziario non risultano essere statisticamente significativi. Alla luce di tali evidenze, lo studio contribuisce ad arricchire lo stato dell’arte sulla c.d. public finance con spunti di ricerca che offrono importanti implicazioni anche di carattere operativo.
Following the adoption of the new capital adequacy and requirements rules, banks currently have two options in order to calculate the minimum capital requirements for credit risk: the standardised approach, supported by external credit assessments, and the internal ratings-based (IRB) approach, relied on banks’ own internal estimates. While banks have been implementing (not quite reliable yet) internal methodologies to estimate corporate ratings long ago, there are not many banks which currently assess state and local governments, and also literature investigates this theme not much. So the research aims analyzing Agencies’ methodologies to identify which are the economic and financial determinants of Italian local government ratings, so as to transfer Agencies’ experience inside banks. Consequently, this analysis applies a multinomial ordered probit model to more than 310 Italian sub-sovereign ratings, as overall assigned by Moody’s, Standard & Poor’s and Fitch Ratings in the period 2004-2008. The results of pooled analysis allow to partially confirm theoretical expectations, and highlight differences of valuation among Agencies as shown in literature. So, only the local GDP per capita is statistically significant and has the expected sign, while other structural and behavioural variables are significant just for two Agencies, but sometimes have the unexpected sign. Instead, contrary to theoretical expectations and empirical evidences from literature, both local debt per capita and borrowing needs are never statistically significant. So this study contributes to improve the literature on public finance pointing out relevant managerial and operational implications too.

O presente trabalho teve por objetivo identificar os fatores que concorrem para que alguns indivíduos na terceira idade se encontrem em situação de pobreza. Mais concretamente, pretendeu-se identificar o perfil socioeconómico de pessoas em situação de pobreza através de um modelo explicativo probit, que estimasse o peso de vários fatores para a referida situação. Porque em Portugal, mais concretamente em zonas rurais, existe uma forte componente de autoconsumo, entrámos em linha de conta com as linhas de pobreza monetária e não-monetária. Esta caracterização é feita a partir do Inquérito às Despesas das Famílias IDEF 2010/2011. O modelo revelou o impacto na probabilidade de se ser pobre (em termos monetários e totais) de variaveis como o nível de ensino do idoso, a sua idade, tipo de ADP onde se encontra inserido, localização rural/ urbana e fonte mais frequente de rendimento. Foram ainda discutidas as implicações do modelo para políticas sociais de apoio.
The present study had the aim to indentify the factors associated to poverty in the elderly. More precisely, we intended to indentify the socioeconomic profile of people in poverty situation through a probit model, capable of estimating the weight of various factors for the referred situation. Because in Portugal, more specifically, in rural areas, there is a strong component o autoconsumption, we took into account the monetray and non-monetary poverty lines. This characterization was made using the Housing Buget Survey 2010/2011. The model revealed an impact on the probability of being poor (in terms of monetary and total income) of variables such as education, age, type of household, and main type of income. We also discuss the implications of the model for social policies.

Les modeles logit et probit polytome multinomial ou conditionnel sont analyses lorsque la variable a expliquer est a plusieurs modalites. L'etude et la modelisation simultanee de plusieurs variables qualitatives fait appel au modele descriptif et explicatif log-lineaire, au modele a reponses multinomiales, ou aux modeles a equations simultanees logit et probit lorsque parmi les variables explicatives figurent des variables endogenes. Enfin dans le cas de donnees binaires individuelles temporelles et sous differentes hypotheses de vraie dependance entre les etats du processus, de non stationnarite et d'heterogeneite, nous etudions les solutions theoriques et la mise en oeuvre informatique des modeles logit et probit associes

The study and the simultaneous modelisation of two or many qualitative variables deal with descriptive and explanatory log linear model, multinomial responses models, and simultaneous equations logit and probit models when some of the explanatory variables are endogeneous. Finally in the case of individual temporal binary data and with some different true dependency hypothesis between process states, non stationarity and heterogeneity, we study not only the theorical solutions but the computational work of logit and probit models associated as well

In the last few years there has been an increase in the Brazilian credit market in terms of volume and modality of credit operations. Besides, Banks, which are the main economics financial mediator, have increased their role on this area. Therefore, in a developing marked, it becomes increasingly important the correct evaluation and administration of the financial risk involved in credit operations: credit risk. In this context, rating classification emerge as a reference to investors. However, as the Brazilian financial market is only slightly developed, rating agencies operating in this country classify only the biggest and more important institutions. The purpose of this study is to develop a rating methodology -based on the ordered probit modelcapable of replicating the rating level of a certain agency. This way, it would be possible to estimate the rating level to those Banks that are not classified by any rating agency.
Nos últimos anos o mercado de crédito brasileiro apresentou grande crescimento em termos de volume e modalidade de operações de crédito. Além disso, observou-se também o aumento da participação dos bancos nesse setor, principais intermediários financeiros da economia. Com isso, em um mercado em desenvolvimento, torna-se cada vez mais importante a correta avaliação e administração do risco financeiro envolvido nas operações: o risco de crédito. Nesse contexto, a classificação de rating surge como referência para investidores. No entanto, como o mercado bancário brasileiro ainda é pouco desenvolvido, apenas instituições de grande porte são classificados pelas agências de rating em funcionamento no país. Este trabalho tem como objetivo o desenvolvimento de uma metodologia de rating baseada no modelo ordered probit, que seja capaz de replicar o nível de rating de uma determinada agência, e assim conseguir estimar o nível de rating para aqueles bancos que não têm a referida classificação de rating

Abstract:
La crisi finanziaria del 2007-2009 non solo ha attaccato l’economia globale in maniera diversificata, ma ha anche generato effetti differenti per i diversi paesi colpiti. Proprio avendo preso atto della crisi di liquidità, che si è profilata in Europa e non solo, e della presenza di situazioni di estrema difficoltà in cui versano i mercati finanziari, si è dovuto riscoprire una tipologia di rischio che prima della crisi era stato considerato secondariamente, si tratta del rischio sistemico. Questa tipologia di rischio non scaturisce, come si pensava inizialmente, solo a seguito di crisi di tipo valutario o di crisi bancarie, ma oltre alle banche ha colpito anche altri settori come hedge funds, assicurazioni, brokers ecc. Per studiare la salute del nostro sistema economico bisogna andare ad analizzare le relazioni esistenti all’interno di un sistema in cui autorità di vigilanza, intermediari finanziari e destinatari dei servizi offerti sono sempre più legati tra loro. Il legame tra queste figure che lavorano nei mercati è così forte che uno shock, che può essere creato da una qualsiasi tipologia di evento negativo, riesce a diffondersi talmente velocemente da riuscire a produrre quell’effetto definito “effetto domino” che va a colpire tutti gli intermediari presenti sul mercato. A seguito di questa “reazione a catena” le tensioni che si vengono a generare a causa del fallimento di una società di intermediazione finanziaria o di una banca, si ripercuotono non solo sugli altri intermediari ma anche nei diversi mercati, provocando il fallimento di tutti quei soggetti che sono presenti sul mercato. La crisi è riuscita a mettere in risalto come gli operatori di mercato non siano capaci di reggere un sistema che, grazie ai progressi tecnologici dell’informazione e ai diffusissimi mezzi di comunicazione, risulta effettivamente complesso. Per questo motivo organizzazioni internazionali e le banche centrali hanno concentrato sforzi e tempo per incrementare modelli e strumenti che siano d’aiuto al fine di valutare, individuare e monitorare costantemente possibili minacce che possono andare ad intaccare la stabilità del sistema. La recente crisi finanziaria ha messo in risalto quelli che sono i limiti del nostro sistema, sia dal punto di vista della regolamentazione, che da quello della supervisione degli intermediari e dei mercati. Il problema più evidente è dato dal fatto che si è sempre posta l’attenzione sulla solidità delle singole componenti che compongono il sistema finanziario, cioè inizialmente si è sempre avuto un approccio micro-prudenziale anziché tenere presente la stabilità del sistema nella sua complessità. La crisi infatti ha mostrato come il sistema è stato vulnerabile, tant’è vero che shock che si ritenevano circoscritti a determinati settori, hanno infine intaccato l’intero sistema.

Neste trabalho é apresentado inicialmente um levantamento da literatura referente a modelos dinâmicos, modelos de regressão não lineares, com variável dependente binária com dados de painel. Estes modelos podem incluir efeitos de várias fontes, tais como, variáveis específicas de interesse, heterogeneidade não observada dos indivíduos e valores desfasados da variável dependente. Neste trabalho iremos analisar aspetos relacionados com a especificação, estimação e inferência do modelo proposto por Wooldridge (2005). O modelo probit é um dos métodos de estimação viáveis de modelos de resposta binária. Este modelo irá ser usado para explicar o uso de internet no telemóvel no período que decorre entre Fevereiro de 2011 e Junho de 2001. Utilizou-se com este fim o software STATA.
This paper presents an initial survey of the literature on dynamic models, nonlinear regression models with binary dependent variable for panel data. These models may include effects of various sources, such as specific variables of interest, unobserved individual heterogeneity and lagged values of the dependent variable. In this paper we analyze aspects related to the specification, estimation and inference of the model proposed by Wooldridge (2005). The probit model is a viable estimation method for binary response models of the type described above. This model will be used to explain the use of mobile internet with dates between February 2011 and June 2011. The software STATA was used for this purpose.

The present work search investigate the chance of financial involution among the Cearenses' municipalities, from accounting data for 150 localities in periods of 2004, 2008 and 2012. The sample comprises 82% of the total number of municipalities in the state of Ceará and the method used follows a binary dependent variable model, with Probit's hypothesis. The econometric model proposed considered variables of financial autonomy,dependence on transfers, personnel expenses and charges, education expenses and health expenses. The estimates leads us to conclude that the chance is significant in that a new municipality that will be created has fundraising less than the average, being considered a economic-financial scenario unfavorable the process of emancipation of districts in the state of Ceará, there is a view that the Cearenses' municipalities are considered to be poor and highly dependent on features of transfers.
O presente trabalho busca investigar a chance de involução financeira dentre os municípios cearenses, a partir dos dados contábeis de 150 localidades nos períodos de 2004, 2008 e 2012. A amostra utilizada compreende 82% do total de municípios no estado do Ceará e o método utilizado segue um modelo de variável dependente binária, com hipótese Probit. O modelo econométrico proposto considerou variáveis de autonomia financeira, dependência de transferências, despesas com pessoal e encargos, gastos com educação e gastos com saúde. As estimativas permitem constatar que a chance é significativa de que um novo município que venha a ser criado possua arrecadação inferior à média, sendo considerado um cenário econômico-financeiro desfavorável ao processo de emancipação de distritos no estado do Ceará, haja vista que os municípios cearenses são considerados pobres e altamente dependentes de recursos de transferências.

Abstract:
La Internet de las cosas (IoT) complica sobremanera la extracción de evidencias electrónicas que pueden servir de base para una investigación forense. En entornos altamente cambiantes y con una densidad de dispositivos tan elevada, es muy difícil entender completamente el contexto de la ofensa. Es por ello que la cooperación de los individuos, aún no estando directamente implicados en la ofensa, puede ser muy relevante para el analista forense. En este artículo se propone un nuevo modelo para la IoT-Forensics, que pretende sentar las bases para la cooperación voluntaria de los individuos en las investigaciones de delitos telemáticos. Para ello, el modelo integra requisitos de privacidad de la norma ISO/IEC 29100:2011 durante todo el ciclo de vida de la investigación.

Abstract:
The ballistic acceleration of electrons inside a semiconductor in response to an applied field has recently been optically observed along with a sub-picosecond burst of terahertz electromagnetic radiation related to the acceleration of the carriers.1 This experiment provides unique challenges to a modeler as it combines broadband electrodynamics with complex transport, e.g., the acceleration of carriers by the field during the finite duration of electron-phonon processes. In our paper, we discuss techniques by which all of these features may be modeled.2 We additionally consider the prospect that may arise in other situations of interest in ultrafast studies of semiconductor devices and circuits.

Abstract:
The paper presents the optimization of the sustainability profit achieved by the production of clamped beams in civil engineering. It proposes to design a range of beams using three different material alternatives: structural steel, reinforced concrete and glulam. For this reason, three optimization models of beams are developed for the three materials. In addition, two different objectives are defined for each material alternative: for the economic profit and for the sustainability profit (which includes the eco costs of global warming). The proposed objectives are subject to the design, resistance and deflection constraints of the clamped beam, which are determined in accordance with the specifications of Eurocodes 2, 3 and 5. The mixed-integer non-linear programming (MINLP) approach is used to find most advantageous material alternative of the beams. GAMS /Dicopt is used. The numerical example presented at the end of the paper clearly shows that reinforced concrete beams have the highest economic and sustainability profit.

Garcia-Bernardo, Javier, and Petr Janský. Profit Shifting of Multinational Corporations Worldwide. Institute of Development Studies, March 2021. http://dx.doi.org/10.19088/ictd.2021.005.

Full text
Abstract:
Multinational corporations (MNCs) avoid taxes by shifting their profits from countries where real activity takes place towards tax havens, depriving governments worldwide of billions of tax revenue. Earlier research investigating the scale and distribution of profit shifting has faced methodological and data challenges, both of which we address. First, we propose a logarithmic function to model the extremely non-linear relationship between the location of profits and tax rates faced by MNCs at those locations – that is, the extreme concentration of profits without corresponding economic activity in a small number of low-tax jurisdictions. We show that the logarithmic model allows for a more accurate identification of profit shifting than linear and quadratic models. Second, we apply the logarithmic model to newly available country-by-country reporting data for large MNCs – this provides information on the activities of large MNCs, including for the first time many low- and lower-middle-income countries. We estimate that MNCs shifted US$1 trillion of profits to tax havens in 2016, which implies approximately US$200-300 billion in tax revenue losses worldwide. MNCs headquartered in the United States and Bermuda are the most aggressive at shifting profits towards tax havens, while MNCs headquartered in India, China, Mexico and South Africa the least. We establish which countries gain and lose most from profit shifting: the Cayman Islands, Luxembourg, Bermuda, Hong Kong and the Netherlands are among the most important tax havens, whereas low- and lower-middle-income countries tend to lose more tax revenue relative to their total tax revenue. Our findings thus support the arguments of low- and lower-middle-income countries that they should be represented on an equal footing during international corporate tax reform debates.

Abstract:
Recently, the Junichiro Koizumi and Shinzo Abe administration has adopted labor reforms, and monetary authorities have updated unconventional monetary policies: quantitative easing of money supply and negative interest rate control. It can be identified that quantitative easing policy and negative interest rate policy have introduced and stimulated new styles of profit-seeking through stock market transactions, which only increases corporate and bank profits under a stagnant labor productivity growth rate. Under such a context, this paper analyzes the changing phase of the profit-seeking patterns of the financial and non-financial sector in Japan. The hypothesis is that the large-scale corporate sector has created a new profit-seeking paradigm and that this has been supported by the monetary control of the so-called "Abenomics".

Full text
Abstract:
Limited-profit housing plays a significant role in Austria’s housing market. Around a quarter of all households live in homes owned or managed by a limited-profit housing association (LPHA). These associations are characterised by a distinct business model, based on the premise of cost-recovery and revolving funds. By deviating both from the logic of for-profit housing and from public housing, LPHAs occupy a distinct ‘Third Sector’ role in Austria’s housing market. This paper describes the key mechanisms and principles of limited-profit housing, including how they are financed, how rents are set, what components are included in price calculations and how they use revolving funds to finance future affordable housing construction. The paper also elaborates the impact of the limited-profit business model on rent levels and draws on a recent study to demonstrate their wider economic impacts.

Michel, Bob, and Tatiana Falcão. Taxing Profits from International Maritime Shipping in Africa: Past, Present and Future of UN Model Article 8 (Alternative B). Institute of Development Studies (IDS), November 2021. http://dx.doi.org/10.19088/ictd.2021.023.

Full text
Abstract:
International maritime shipping is an essential part of global business. Since the establishment of the current international tax regime in the 1920s, there has been a consensus that profits generated by this business are taxable only in the residence state –the state where the shipowners are located. Source states – the port states where business physically takes place – are generally expected to exempt income from international shipping. This standard is currently reflected in Article 8 of the OECD Model and Article 8 (Alternative A) of the UN Model, and is incorporated in the vast majority of bilateral tax treaties currently in force. Exclusive residence state taxation of shipping profits is problematic when the size of mercantile fleets and shipping flows between two states are of unequal size. This is often the case in relations between a developed and developing country. The latter often lack a substantial domestic mercantile fleet, but serve as an important revenue-generating port state for the fleet of the developed country. To come to a more balanced allocation of taxing rights in such a case, a source taxation alternative has been inserted in UN Model Article 8 (Alternative B). From its inception, Article 8B has been labelled impractical due to the lack of guidance on core issues, like sourcing rules and profit allocation. This gap is said to explain the low adoption rate of Article 8B in global tax treaty practice. In reality, tax treaty practice regarding Article 8B is heavily concentrated and flourishing in a handful of countries in South/South-East Asia – Bangladesh, India, Indonesia, Myanmar, Pakistan, the Philippines, Sri Lanka and Thailand. All these countries subject non-resident shipping income to tax in their domestic income tax laws. Except for India, all countries are able to exercise these domestic tax law rules in relation to shipping enterprises located in the biggest shipowner states, either because they have a treaty in place that provides for source taxation or because there is no treaty at all and thus no restriction of domestic law. None of the relevant tax treaties contain a provision that incorporates the exact wording of Article 8B of the UN Model. If other countries, like coastal countries in sub-Saharan Africa, are looking to implement source taxation of maritime shipping income in the future, they are advised to draw on the South/South-East Asian experience. Best practice can be distilled regarding sourcing rule, source tax limitation, profit attribution and method of taxation (on gross or net basis). In addition to technical guidance on tax, the South/South-East Asian experience also provides important general policy considerations countries should take into account when determining whether source taxation of maritime shipping profits is an appropriate target for their future tax treaty negotiations.

Full text
Abstract:
Renewable, decentralised mini-grids are a promising technology for electrifying remote communities in sub-Saharan Africa. However, most mini-grids struggle not only to obtain a profit, but also to recover costs. This Policy Briefing describes the case of a private, for-profit mini-grid business model which also developed the productive commercial uses of electricity to achieve financial sustainability. The model failed due to high regulatory risks, initially high tariffs, and complex management of commercial activities. We argue that public–private partnerships and collaboration with local agrobusinesses could improve affordability, reduce risks, and ensure long-term sustainability.

Abstract:
The advent of American shale oil and its prospects for continued production growth have raised concerns about whether oil refineries can handle the increasingly lighter crude oil supply. To provide a perspective on this issue, we run a global oil refining model for the years from 2017 to 2030. The model’s objective is to maximize refining industry profits in eight global regions, taking into account around 100 grades of crude oil.
