Land taxes in a Latin American context

Since Henry George (1839-1897) economists have been arguing that a tax on unimproved land is an ideal tax on efficiency grounds. Output taxes, on the other hand, have distortionary effects on the economy. This paper shows that under asymmetric information output taxes might be used along with land tax in order to implement an optimal taxation scheme in a Latin American context, i.e., where land rental markets are relatively thin, land property provides non-agricultural payoffs and there is nonrevenue objectives of land taxation. Also, the model has two implications that can be tested empirically: (i) there is evasion when schemes based only on land taxes are implemented; (ii) this evasion is more severe for large landholders.

The influence of materialism on consumption indebtedness in the context of low income consumers from the city of São Paulo

This research is in the domains of materialism, consumer vulnerability and consumption indebtedness, concepts frequently approached in the literature on consumer behavior, macro-marketing and economic psychology. The influence of materialism on consumer indebtedness is investigated within a context that is characterized by poverty and by factors that cause vulnerability, such as high interest rates, limited access to credit and to quality affordable goods. The objectives of this research are: to produce a materialism scale that is well adapted to its environment, characterizing materialism adequately for the population studied; to compare results obtained with results of other studies; and to measure the relationship between materialism, socio-demographic variables, attitude to debt and consumption indebtedness. The primary data used in the analyses were collected from field research carried out in August, 2005 that relied on a probabilistic household sample of 450 low income individuals who live in poor regions of the city of Sao Paulo. The materialism scale, adapted and translated into Portuguese from Richins (2004), proved to be very successful and encourages new work in the area. It was noted that younger adults tend to be more materialistic than older ones; that illiterate adults tend to be less materialistic than those who did literacy courses when they were already adults; and that gender, income and race are not associated with the materialism construct. Among the other results, a logistic regression model was developed in order to distinguish those individuals who have an installment plan payment booklet from those who do not, based on materialism, socio-demographic variables and purchasing and consumer habits. The proposed model confirms materialism as a behavioral variable useful for forecasting the probability of an individual getting into debt in order to consume, in some cases almost doubling the chance of occurrence of this event. Findings confirm the thesis that it is not only adverse economic factors that lead people to get into debt; and that the study of demand for credit for consumption purposes must, of necessity, include variables of a psychological nature. It is suggested that the low income materialistic consumer experiences feelings of powerlessness and exclusion because of the gap that exists between their possessions and their desires. Lines of conduct to combat this marginalization from the consumer society are drawn targeting marketing professionals, public policy makers and vulnerability researchers. Finally, the possibility of new studies involving the materialism construct, which is central to literature on consumer behavior, albeit little used in empirical studies in Brazil, are discussed.

The effects of trust in Brazilian PNPs: interpersonal and interorganizational trust in the cultural sector social organizations in São Paulo, Brazil

This study seeks to evaluate how enterorganizational and interpersonal trust affects the degree of State interference in the operations of public-nonprofit partnerships (PNPs). We conducted a qualitative case study in two Brazilian PNPs, Projeto Guri and Orquestra Sinfônica do Estado de São Paulo, through documental analysis and semi-structured interviews. Content analysis of the data yielded a trust framework that begins to explain how a variety of factors, including the protective qualities of the management contract and the strength of the board, moderate the relationship between interpersonal and interorganizational trust in PNPs. The study reveals that unlike Zaheer et al (1998), interpersonal trust had a unique and prominent effect on State interference and types of collaboration in PNPs. Parting from the suggestions by previous authors to contextualize PNP literature findings, the framework takes into account the highly personalistic qualities of Brazilian culture as well as historical and institutional context while highlighting the crucial role of interpersonal trust in Brazilian PNPs.

Anticipatory effects in the FTSE 100 index revisions

This paper examines the price impact of trading due to expected changes in the FTSE 100 index composition. We focus on the latter index because it employs publicly-known objective criteria to determine membership and hence it provides a natural context to investigate anticipatory trading e ects. We propose a panel-regression event study that backs out these anticipatory e ects by looking at the price impact of the ex-ante proba-bility of changing index membership status. Our ndings reveal that anticipative trading explains about 40% and 23% of the cumulative abnormal returns of additions and deletions, respectively. We con rm these in-sample results out of sample by tracking the performance of a trading strategy that relies on the addition/deletion probability estimates. The perfor-mance is indeed very promising in that it entails an average daily excess return of 11 basis points over the FTSE 100 index.

Feasible multilateralism and the effects of regionalism

Recent research has underlined the efficiency of the GATT/WTO rules from the standpoint of politically motivated governments, emphasizing that the current multilateral rules are capable of delivering a politically efficient equilibrium. Such an equilibrium is, however, economically inef- ficient. Global free trade, in particular, is generally unattainable even in a fully cooperative world, provided that governments have distributive motivations. In such a context, we show that regional trade agreements can help move the world towards a welfare superior equilibrium. The reason is that, as members of regional trade agreements lower trade barriers against one another, they are induced to reduce their multilateral tariffs as well. Once we account for these endogenous changes–and only then–we find that regionalism can raise world welfare even in a fully cooperative (but political) world. We also find, however, that members are likely to gain "too much" from regional integration, thereby harming outsiders.

Bias and size effects of price-comparison search engines : theory and experimental evidence

We analyze the impact on consumer prices of the size and bias of price comparison search engines. In the context of a model related to Burdett and Judd (1983) and Varian (1980), we develop and test experimentally several theoretical predictions. The experimental results confirm the model’s predictions regarding the impact of the number of firms, and the type of bias of the search engine, but reject the model’s predictions regarding changes in the size of the index. The explanatory power of an econometric model for the price distributions is significantly improved when variables accounting for risk attitudes are introduced.
