Transfers, contracts and regulation: a new institutional economics perspective on the changing provision of social housing in Britain

Social housing policy in the UK mirrors wider processes Associated with shifts in broad welfare regimes. Social housing has moved from dominance by state housing provision to the funding of new investment through voluntary sector housing associations to what is now a greater focus on the regulation and private financing of these not-for-profit bodies. If these trends run their course, we are likely to see a range of not-for-profit bodies providing non-market housing in a highly regulated quasi-market. This paper examines these issues through the lens of new institutional economics, which it is believed can provide important insights into the fundamental contractual and regulatory relationships that are coming to dominate social housing from the perspective of the key actors in the sector (not-for-profit housing organisations, their tenants, private lenders and the regulatory state). The paper draws on evidence recently collected from a study evaluating more than 100 stock transfer organisations that inherited ex-public housing in Scotland, including 12 detailed case studies. The paper concludes that social housing stakeholders need to be aware of the risks (and their management) faced across the sector and that the state needs to have clear objectives for social housing and coherent policy instruments to achieve those ends.

The level of compliance with the International Code of marketing of breast-milk substitutes: does it matter to stock markets?

The present paper explores, theoretically, and empirically, whether compliance with the International Code of marketing of breast-milk substitutes impacts on financial performance measured by stock markets. The empirical analysis, which considers a 20-year period, shows that stock markets are indifferent to the level of compliance by manufacturers with the International Code. Two important issues emerge from this result. Based on our finding that financial performance as measured by stock markets cannot explain the level of compliance, the first issue refers to what alternative types of mechanisms drive manufacturers who comply the least with voluntary codes such as the International Code. Conversely, from our finding that stock markets do not reward the most compliant, the second issue raised is an inherent weakness of stock markets to fully incorporate social and environmental values.

Rerum cognoscere causas: part II - opportunities generated by the agency/structure debate and suggestions for clarifying the social theoretic position of system dynamics

This is the second half of a two-part paper dealing with the social theoretic assumptions underlying system dynamics. In the first half it was concluded that analysing system dynamics using traditional, paradigm-based social theories is highly problematic. An innovative and potentially fruitful resolution is now proposed to these problems. In the first section it is argued that in order to find an appropriate social theoretic home for system dynamics it is necessary to look to a key exchange in contemporary social science: the agency/structure debate. This debate aims to move beyond both the theories based only on the actions of individual human agents, and those theories that emphasise only structural influences. Emerging from this debate are various theories that instead aim to unite the human agent view of the social realm with views that concentrate solely on system structure. It is argued that system dynamics is best viewed as being implicitly grounded in such theories. The main conclusion is therefore that system dynamics can contribute to an important part of social thinking by providing a formal approach for explicating social mechanisms. This conclusion is of general significance for system dynamics. However, the over-arching aim of the two-part paper is to increase the understanding of system dynamics in related disciplines. Four suggestions are therefore offered for how the system dynamics method might be extended further into the social sciences. It is argued that, presented in the right way, the formal yet contingent feedback causality thinking of system dynamics should diffuse widely in the social sciences and make a distinctive and important contribution to them.

Are price limits on futures markets that cool? evidence from the brazilian merchantile & futures exchange

This paper investigates the impact of price limits on the Brazil- ian future markets using high frequency data. The aim is to identify whether there is a cool-off or a magnet effect. For that purpose, we examine a tick-by-tick data set that includes all contracts on the São Paulo stock index futures traded on the Brazilian Mercantile and Futures Exchange from January 1997 to December 1999. Our main finding is that price limits drive back prices as they approach the lower limit. There is a strong cool-off effect of the lower limit on the conditional mean, whereas the upper limit seems to entail a weak magnet effect on the conditional variance. We then build a trading strategy that accounts for the cool-off effect so as to demonstrate that the latter has not only statistical, but also economic signifi- cance. The resulting Sharpe ratio indeed is way superior to the buy-and-hold benchmarks we consider.

Are price limits on futures markets that cool?: evidence from the Brazilian Mercantile and Futures Exchange

This paper investigates the impact of price limits on the Brazilian futures markets using high frequency data. The aim is to identify whether there is a cool-off or a magnet effect. For that purpose, we examine a tick-by-tick data set that includes all contracts on the S˜ao Paulo stock index futures traded on the Brazilian Mercantile and Futures Exchange from January 1997 to December 1999. The results indicate that the conditional mean features a floor cool-off effect, whereas the conditional variance significantly increases as the price approaches the upper limit. We then build a trading strategy that accounts for the cool-off effect in the conditional mean so as to demonstrate that the latter has not only statistical, but also economic significance. The in-sample Sharpe ratio indeed is way superior to the buy-and-hold benchmarks we consider, whereas out-of-sample results evince similar performances.

Cooperação, capital social e desempenho econômico: um estudo analítico

O objetivo deste artigo é definir capital social como infra-estrutura social e procurar incluir tal variável num modelo de crescimento econômico. O capital social, visto de tal forma, teria impacto sobre a produtividade dos fatores de produção. Em primeiro lugar, discutirei como as variáveis institucionais podem afetar o crescimento. Em segundo lugar, analisando várias definições de capital social, mostrarei quais são as virtudes e problemas de cada uma e definirei, para a introdução de tal variável num modelo de crescimento, capital social como infra-estrutura social. Por fim, tentarei abrir espaço para estudos empíricos posteriores, tanto no campo da mensuração de estoque de capital social, como em estudos entre economias no sentido de captar o impacto do capital social sobre o crescimento econômico.

O poder social

o presente trabalho teve por objetivo investigar o relacionamento entre locus externo de causalidade e aquiescência de detentores de poder e a so1icitações de subordinados. Pesquisas anteriores realizadas nos Estado Unidos demonstraram das condições que afetam os indivíduos em situação de poder levando-os a atender as solicitações de dependentes. Esse estudo constitui uma réplica parcial do experimento de Schopler e Mathew B (1965) para o teste da mesma hipótese - o detentor de poder que percebe a dependência de seu parceiro motivada por fatores externos dar-lhe-á mais ajuda que quando percebe a dependência do parceiro motivada por auto escolha (fatores internos) - com sujeitos brasileiros. O mesmo “design” serviu para o teste de duas hipóteses adicionais: a) o detentor de poder ajuda mais sem parceiro dependente quando o custo da ajuda é baixo (hipótese de Thibaut e Kelly, 1967); b) o detentor de poder ajuda menos o parceiro, percebido como dependente por força de circunstâncias externas, quando conhece antecipadamente qual a sua solicitação (hipótese original deste trabalho). Os resultados confirmaram as hipóteses ao nível de 0,05. A discussão dos resultados obtidos foi desenvolvida em termos das teorias da troca e da reatância. Com base nos resu1tados conclui-se que: (1) as relações de poder não parecem ser influenciadas pela cultura em que os agentes estão inseridos; (2) a oposição à liberdade perdida pode explicar o menor atendimento a solicitações pré-conhecidas.

O conceito de poder social

A dissertação procura analisar o conceito de poder numa perspectiva de questionamento da Psicologia Social notadamente com respeito à relevância de seus achados para a sociedade e à vinculação de suas formulações com a estrutura social vigente. Verifica-se a polissemia do conceito, pertencente a diferentes níveis do conhecimento e possuindo um referencial empírico ampliado, o que por sua vez gera divergências em sua conceituação. Tendo seu lugar de demarcação nas relações interpessoais, intra e intergrupais, organizacionais e de classe, seu significado mescla-se ao de termos como influência, controle, autoridade, dominação, que são muitas vezes intercambiáveis num determinado texto. Seu exercício caracteriza a relação de dominação-subordinação e é visto como decorrente da posse de recursos, implicando em resistência por parte dos subordinados e em sua percepção como beneficiador unicamente de seu detentor. Entende-se como um esforço da Psicologia Social em prol da manutenção da ordem social seus trabalhos visando elaborar novas formas de manipulação dos conflitos consequentes ao exercício do poder. Enquanto a visão desta disciplina é eminentemente psicológica, desvinculada do contexto social, em Ciências Políticas e Sociologia o conceito insere-se numa reflexão sobre a macro-estrutura sem, contudo, dispensar a utilização de variáveis psicológicas. Motivações e habilidades do detentor do poder e valores, percepções e expectativas do elemento subordinado são fatores presentes nas diferentes reflexões analisadas, tanto nas oriundas da Psicologia quanto na integracionista, na elitista, na pluralista e na da troca, ausentando-se somente da marxista que recorta o conceito de poder no campo das lutas de classe.

A democratização da jurisdição constitucional: instrumentos de participação social

Este trabalho se propõe a estudar a jurisdição constitucional sob a perspectiva pós-positivista com destaque para o controle de constitucionalidade concentrado. O pós-positivimo quebrou os paradigmas do direito constitucional clássico dando ao Poder Judiciário uma grande ascensão política realçando a dificuldade contramajoritária do controle de constitucionalidade concentrado. Ademais, as diversas manifestações da jurisdição constitucional que alijam o cidadão comum da Corte fazem do Supremo Tribunal Federal um tribunal isolado. As novas facetas do Poder Judiciário, especialmente do STF, têm gerado um déficit democrático na jurisdição constitucional. Este déficit democrático gera desequilíbrio entre as duas dimensões do Estado Democrático de Direito, onde a democracia se encontra em desvantagem em relação ao ideal constitucionalista. Na tentativa de diminuir o déficit democrático da jurisdição constitucional este trabalho se assenta sobre a importância de se reforçarem os instrumentos de participação social no controle de constitucionalidade concentrado: amicus curiae, audiências públicas e visitas in loco. Além de reequilibrar o Estado de Direito, o reforço desses instrumentos traz a racionalização das decisões em sede de controle concentrado, uma vez que promove uma troca de experiência entre o julgador e a realidade possibilitando a ele proferir decisões mais eficientes.

Social norms and money

In an economy where there is no double coincidence of wants and without recordkeeping of past transactions, money is usually seen as the only mechanism that can support exchange. In this paper, we show that, as long as the population is finite and agents are sufficiently patient, a social norm establishing gift-exchange can substitute for money. Notwithstanding, for a given discount factor, the growth of the population size eventually leads to the breakdown of the social norm, while money still works. 1 Introduction

The impact on the stationary state income of a pay-as-you-go system of social security

A model of overlapping generations in continuous time is composed. IndividuaIs pass through two distinct time periods during their life times. During the first period, they work, save and have a death probability equal to zero. During the second, from the periods T after birth, their probability of death changes to p and then they retire. Capital stock and the stationary state in come are calculated for two situations: in the first, people live from their accumulated capital after retirementj in the second, they live from a state transfer payment through income taxo To simplify matters, in this preliminary version, it is supposed that there is no population growth and that the instantaneous elasticity substitution of consumption is unitary.

Neighborhood information exchange and voter participation : an experimental study

We study the effect of social embeddedness on voter turnout by investigating the role of information about other voters’ decisions. We do so in a participation game, where some voters (‘receivers’) are told about some other voters’ (‘senders’) turnout decision at a first stage of the game. Cases are distinguished where the voters support the same or different candidates or where they are uncertain about each other’s preferences. Our experimental results show that such information matters. Participation is much higher when information is exchanged than when it is not. Senders strategically try to use their first mover position and some receivers respond to this.

Consumption-Wealth Ratio and Expected Stock Returns: Evidence from Panel Data on G7 Countries

Using the theoretical framework of Lettau and Ludvigson (2001), we perform an empirical investigation on how widespread is the predictability of cay {a modi ed consumption-wealth ratio { once we consider a set of important countries from a global perspective. We chose to work with the set of G7 countries, which represent more than 64% of net global wealth and 46% of global GDP at market exchange rates. We evaluate the forecasting performance of cay using a panel-data approach, since applying cointegration and other time-series techniques is now standard practice in the panel-data literature. Hence, we generalize Lettau and Ludvigson's tests for a panel of important countries. We employ macroeconomic and nancial quarterly data for the group of G7 countries, forming an unbalanced panel. For most countries, data is available from the early 1990s until 2014Q1, but for the U.S. economy it is available from 1981Q1 through 2014Q1. Results of an exhaustive empirical investigation are overwhelmingly in favor of the predictive power of cay in forecasting future stock returns and excess returns.

O novo federalismo social e o Rio: desenho de programas complementares de transferência de renda condicionada

Brazilian public policy entered in the so-called new social federalism through its conditional cash transfers. States and municipalities can operate together through the nationwide platform of the Bolsa Familia Program (BFP), complementing federal actions with local innovations. The state and the city of Rio de Janeiro have created programs named, respectively, Renda Melhor (RM) and Família Carioca (FC). These programs make use of the operational structure of the BFP, which facilitates locating beneficiaries, issuing cards, synchronizing payment dates and access passwords and introducing new conditionalities. The payment system of the two programs complements the estimated permanent household income up to the poverty line established, giving more to those who have less. Similar income complementation system was subsequently adopted in the BFP and the Chilean Ingreso Ético Familiar, which also follow the principle of estimation of income used in the FC and in the RM. Instead of using the declared income, the value of the Rio cash transfers are set using the extensive collection of information obtained from the Single Registry of Social Programs (Cadastro Único): physical configuration of housing, access to public services, education and work conditions for all family members, presence of vulnerable groups, disabilities, pregnant or lactating women, children and benefits from other official transfers such as the BFP. With this multitude of assets and limitations, the permanent income of each individual is estimated. The basic benefit is defined by the poverty gap and priority is given to the poorest. These subnational programs use international benchmarks as a neutral ground between different government levels and mandates. Their poverty line is the highest of the first millennium goal of the United Nations (UN): US$ 2 per person per day adjusted for the cost of living. The other poverty line of the UN, US$ 1.25, was implicitly adopted as the national extreme poverty line in 2011. The exchange of methodologies between federal entities has happened both ways. The FC began with the 575,000 individuals living in the city of Rio de Janeiro who were on the payroll of the BFP. Its system of impact evaluation benefited from bi-monthly standardized examinations. In the educational conditionalities, the two programs reward students' progress, a potential advantage for those who most need to advance. The municipal program requires greater school attendance than that of the BFP and the presence of students’ parents at the bimonthly meetings held on Saturdays. Students must achieve a grade of 8 or improve at least 20% in each exam to receive a bi-monthly premium of R$50. In early childhood, priority is given to the poor children in the program Single Administrative Register (CadÚnico) to enroll in kindergarten, preschools and complementary activities. The state program reaches more than one million people with a payment system similar to the municipal one. Moreover, it innovates in that it transfers awards given to high school students to savings accounts. The prize increases and is paid to the student, who can withdraw up to 30% annually. The total can reach R$3,800 per low-income student. The State and the city rewarded already education professionals according to student performance, now completing the chain of demand incentives on poor students and their parents. Increased performance is higher among beneficiaries and the presence of their guardians at meetings is twice compared to non beneficiaries; The Houston program, also focuses on aligning the incentives to teachers, parents and students. In general, the plan is to explore strategic complementarities, where the whole is greater than the sum of its parts. The objective is to stimulate, through targets and incentives, synergies between social actors (teachers, parents, students), between areas (education, assistance, work) and different levels of government. The cited programs sum their efforts and divide labor so as to multiply interactions and make a difference in the lives of the poor.
