The transport economics literature has indicated that introduction of competition for the market in urban bus services (i.e. by means of competitive bidding) could promote cost-efficiency with low fares and better quality services. Therefore, this paper analyse the main outcomes and the latest...

The public policies on mass transit and other economic policies have been unable to avoid increasing mass transit costs and urban bus fares, which places a burden on a majority of the population depending on public transit. This study analyzes the variations in urban bus fares and households...

Using techniques from evolutionary game theory, we analyze potential games with continuous player sets, a class of games which includes a general model of network congestion as a special case. We concisely characterize both the complete set of Nash equilibria and the set of equilibria which are...

Supporters of left-wing parties typically place more emphasis on redistributive policies than right-wing voters. I investigate whether this difference in tolerating inequality is amplified by suspicious success - achievements that may arise from cheating. Using a laboratory experiment, I...

The paper seeks to analyze the distribution of real estate assets among Brazilian families and Imposto Predial e Territorial Urbano (IPTU) - property tax - their main form of taxation. The text points out that real estate property usufruct is more concentrated than family income itself, despite...

Using a factor decomposition of the Gini coefficient we measure the contribution to inequality of direct monetary income flows to and from the Brazilian State. The income flows from the State include public servants' earnings, Social Security pensions, unemployment benefits and Social Assistance...

The rational expectations assumption, e.g. in life-cycle models and portfolio-choice models, prescribes agents to have model-consistent beliefs and to avoid systematic prediction errors. In reality, justi cation and identification of expectations are nontrivial. One way to solve this problem is...

We study the optimal design of student financial aid as a function of parental income. We derive optimal financial aid formulas in a general model. For a simple model version, we derive mild conditions on primitives under which poorer students receive more aid even without distributional...

What are the implications of (endogenous) directed technical change for the design of redistributive income taxes? I study this question in a Mirrleesian economy augmented to include endogenous technology development and adoption choices by firms. Under certain conditions, any progressive tax...
