Budgeting and resource allocation in universities, a public choice approach

The calls urging colleges and universities to improve their productivity are coming thick and fast in Brazil. Many studies are suggesting evaluation systems and external criteria to control universities production in qualitative terms. Since universities and colleges are not profit-oriented organizations (considering just the fair and serious researching and teaching organizations, of course) the traditional microeconomics and administrative variables used to measure efficiency do not have any direct function. In this sense, It could be created a as if market control system to evaluate universities and colleges production. The budget and the allocation resources mechanism inside it can be used as an incentive instrument to improve quality and productivity. It will be the main issue of this paper.

What is the role of bookbuilding in bond allocation ? : evidence from Brazil

A dissertação tem como objetivo analisar dois aspectos do processo de bookbuilding nas emissões de debêntures no mercado brasileiro. O primeiro aspecto é verificar se o underwriter utiliza, a exemplo do que ocorre no Initial Public Offering (IPO) de ações, o poder discricionário nas alocações das debêntures entre os investidores. O segundo consiste em encontrar as características, tanto do emissor quanto do investidor, que influenciam na eficiência do bidder no processo de bookbuilding. Para realizar os testes empíricos foi utilizada uma base de dados composta por 40 books1 (totalizando 727 bids) fornecidos por um banco de investimento.Verifica-se que o underwriter não beneficia nenhum investidor na alocação final das debêntures. Essa afirmação fica evidenciada quando se calcula a diferença entre alocação final (efetivamente recebida pelo investidor) e alocação teórica (estimada com base no método pro-rata) para os 27 books (totalizando 557 bids) que apresentam demanda superior a oferta. A diferença é nula para 96.6% da amostra, sendo que das 19 observações não nulas, 15 possuem diferença absoluta de uma debênture entre a alocação teórica e a final, resultado explicado em função do arredondamento das alocações.Contrariando a teoria de leilão de titulos públicos, onde autores, como Scott and Wolf (1979), defendem que os investidores devem utilizar o step bid como estratégia ótima de bid, este trabalho verificou que no caso de bookbuilding de debêntures no mercado brasileiro, os investidores usuários de step bid posssuem menos chances de ter seu bid atendido plenamente pelo underwriter. Quando o investidor é um gestor de recursos de terceiros (asset management), aumenta-se a possibilidade de ter sua demanda atendida. O maior sucesso do asset management no bookbuilding deve-se às peculiaridades do mercado brasileiro: (i) somente investidores locais participam dos bookbuilding, já que investidores estrangeiros possuem preferência e incentivos por títulos públicos; (ii) gestores de recursos de terceiros representam 75% da demanda por debêntures; (iii) o mercado de gestão de recursos é concentrado: os 5 maiores gestores concentram 60% da indústria. Com isso os gestores de recursos podem desenvolver uma expertise própria, já que são os principais demandadores e frequentemente participam dos bookbuilding. As características do emissor também influenciam no desempenho dos bidders: as debêntures de baixo e médio risco aumentam a possibilidade do bidder ter seu pedido atendido na íntegra. Além disso, como era esperado, quanto maior for a demanda do título, mais dificil é para o investor conseguir a quantidade desejável.

Cartéis em leilões: atuação e medidas de combate

Leilão é um procedimento de alocação de recursos com boas propriedades. Apresento a literatura teórica de leilões a qual demonstra, que sob diversas condições, leilões levam à alocação eficiente de recursos e maximização da receita do leiloeiro. Entretanto estes resultados valem apenas se os participantes do leilão não estejam organizados em cartéis. Um Cartel é uma organização que inibe a concorrência entre firmas. A atuação de um cartel pode ou não levar a uma alocação eficiente de recursos, mas a receita do leiloeiro será sempre prejudicada. Analiso a literatura teórica de cartel em leilões de objeto único que caracteriza formas de coordenação do cartel, estratégias de atuação e sua sustentabilidade. Apresento os desafios que o cartel deve superar. Mais ainda, proponho medidas que devem ser tomadas, caso haja suspeita de existência de cartel. O leilão de primeiro preço é o menos suscetível a ação de cartéis, pois nele há incentivo para as firmas desviarem das orientações do cartel. O combate a cartéis é avaliado por meio da taxa de desconto necessária para o cartel existir. Se a taxa de desconto necessária é menor significa um cartel mais difícil de ser sustentado. Demonstro que o preço de reserva randômico é melhor para combater cartéis do que o preço de reserva fixo em leilões de primeiro preço que se repetem.

Allocation of authority in franchise chains

This article investigates the level of delegation in franchise chains, distinguishing the two most relevant franchising models: Business Format Franchising and Learning Network Franchising. The two models basically differ on the level of real authority (effective control over decisions) exercised by the franchisors. Differences in business features, such as the required standardization, monitoring costs and consumer sensitivity to variations in product attributes (consumer measurement costs), explain the adoption of the different models of franchising. These variables affect the trade-off between the risk of brand name loss and the gains in knowledge sharing and learning within the network. The higher the need for standardization, the higher is the risk of brand name loss, and, consequently, the more likely the franchisor will adopt an organizational design that confers more control over franchisees’ decisions, such as business format franchising. This paper presents two case studies with Brazilian food franchise chains that illustrate the main argument and suggest additional propositions. Moreover, an empirical analysis of 223 franchise chains provides additional support to the hypothesis of a negative the effect of required standardization on the level of delegation.

Retail competition and shelf space allocation

We develop a model to study shelf space allocation in retail. Retailers compete for consumers not only choosing prices but also by the space allocated to each product on shelves. Our approach depart from the existing literature on shelf allocation, as we model the problem of price setting and shelf allocation in an oligopolistic retail market. We present a simple model of retail competition in which prices are dispersed in the crosssection of stores but shelf allocation is not.

Centralized allocation in multiple markets

We study the problem of centralized allocation of indivisible objects in multiple markets. We show that the set of allocation rules that are group strategy-proof and Pareto-efficient are sequential dictatorships. Therefore, the solution of the joint al-location in multiple markets is significantly narrower than in the single-market case. Our result also applies to dynamic allocation problems. Finally, we provide conditions under which the solution of the single-market allocation coincides with the multiple-market case, and we apply this result to the study of the school choice problem with sibling priorities.

Durante muitos anos uma controversa questão tem ocupado tanto os discursos acadêmicos quanto os financeiros. O problema a ser resolvido diz respeito à evolução passada dos preços das ações e se tal evolução poderia ser utilizada para prever o comportamento dos preços futuros dessas ações.

Estimation of random coefficients logit demand models: an application to the Brazilian fixed income fund market

Estimation of demand and supply in differentiated products markets is a central issue in Empirical Industrial Organization and has been used to study the effects of taxes, merges, introduction of new goods, market power, among others. Logit and Random Coefficients Logit are examples of demand models used to study these effects. For the supply side it is generally supposed a Nash equilibrium in prices. This work presents a detailed discussion of these models of demand and supply as well as the procedure for estimation. Lastly, is made an application to the Brazilian fixed income fund market.

Portifolio selection with random transaction costs

Transaction costs have a random component in the bid-ask spread. Facing a high bid-ask spread, the consumer has the option to wait for better terms oI' trade, but only by carrying an undesirable portfolio balance. We present the best policy in this case. We pose the control problem and show that the value function is the uni que viscosity solution of the relevant variational inequality. Next, a numerical procedure for the problem is presented.

Common agency with informed principals

We analyze a common agency game under asymmetric information on the preferences of the non-cooperating principals. Asymmetric information introduces incentive compatibility constraints which rationalize the requirement of truthfulness made in the earlier literature on common agency games under complete information. There exists a large class of differentiable equilibria which are ex post inefficient and exhibit free-riding. We then characterize some interim efficient equilibria. Finally, there exists also a unique equilibrium allocation which is robust to random perturbations. This focal equilibrium is characterized for any distribution of types.

Work, study, both or neither? time allocation of Brazilian teenagers

Labor force participation among youth is extremely high in Brazil when compared to countries with a similar economic background. In Argentina and Chile labor force participation, among those with 10 to 14 years old, is around 1% while in Brazil this rate is as high as 17 %. For the those between 15 and 19 years old these figures are around 10% in Chile, 15% in Argentina and 53% in Brazil. On the other hand the data on school attendance give a more optimistic picture. The percentage of children, between 10 and 14 years old, enrolled in school increased steadily from 79% to 95% from 1981 to 1998 and with age between 15 and 19, from 46% to 66% in the same period. These figures are close to the ones presented by Chile and Argentina. around 99% among the youngest group and around 70% for the 15 to 19 years old group. The objective of the paper is to understand the determinants of the time allocation decision of the Brazilian youth during the last twenty years. Using a multinomial logit regression we investigate the conditional effect of various micro and macro variables on the time allocation decision for the 1991 to 1998 period. Our main findings are: working and studying became the most likely allocation among the youngest in the poor rural areas and, in general, to study, whether working or not, became less dependent on family background for the youngest group but not for the older.

The impact of property rights and its limits

The empirical evaluation of the effect of land property rights typically suffers from selection problems. The allocation of property rights across households is usually not random but based on wealth, family characteristics, political clientelism, or other mechanisms built on differences between the groups that acquire property rights and the groups that do not. In this paper, we address this selection concern exploiting a natural experiment in the allocation of property rights. Twenty years ago, a homogenous group of squatters occupied a piece of privately owned land in a suburban area of Buenos Aires, Argentina. When the Congress passed an expropriation law transferring the land from the former owners to the squatters, some of the former owners surrendered the land (and received a compensation), while others decide to sue in the slow Argentine courts. These different decisions by the former owners generated an allocation of property rights that is exogenous to the characteristics of the squatters. We take advantage of this natural experiment to evaluate the effect of the allocation of urban land property rights. Our preliminary results show significant effects on housing investment, household size, and school attrition. Contradicting De Soto's hypotheses, we found nonsignificant effects on labor income and access to credit markets.

The power of the purse : what do the data say on US federal budget allocation to the states?

This paper provides new evidence on the determinants of the allocation of the US federal budget to the states and tests the capability of congressional, electoral and partisan theories to explain such allocation. We find that socio-economic characteristics are important explanatory variables but are not sufficient to explain the disparities in the distribution of federal monies. First, prestige committee membership is not conducive to pork-barrelling. We do not find any evidence that marginal states receive more funding; on the opposite, safe states tend to be rewarded. Also, states that are historically "swing" in presidential elections tend to receive more funds. Finally, we find strong evidence supporting partisan theories of budget allocation. States whose governor has the same political affiliation of the President receive more federal funds; while states whose representatives belong to a majority opposing the president party receive less funds.

Do police reduce crime? Estimates using the allocation of police forces after a terrorist attack

An important challenge in the crime literature is to isolate causal effects of police on crime. Following a terrorist attack on the main Jewish center in the city of Buenos Aires, Argentina, in July 1994, all Jewish institutions (including schools, synagogues, and clubs) were given 24-hour police protection. Thus, this hideous event induced a geographical allocation of police forces that can be presumed to be exogenous in a crime regression. Using data on the location of car thefts before and after the terrorist attack, we find a large deterrent effect of observable police presence on crime. The effect is local, with little or no appreciable impact outside the narrow area in which the police are deployed.
