Do Competition and Ownership Matter? Evidence from Local Public Transport in Europe
Provedor de dados: 31
Autores: Boitani,   Andrea; Nicolini,   Marcella; Scarpa,   Carlo.
This paper investigates how the ownership and the procedure for the selection of firms operating in the local public transport sector affect their productivity. In order to compare different institutional regimes, we carry out a comparative analysis of 72 companies operating in large European cities. This allows us to consider firms selected either through competitive tendering or negotiated procedures. The analysis of the data on 77 European firms over the period 1997-2006 indicates that firms operate under constant returns to scale. Retrieving the residuals we obtain a measure of total factor productivity, which we regress on firm and city characteristics. We find that when firms are totally or partially in public hands their productivity is lower....

Privatizing Highways in Latin America: Is It Possible to Fix What Went Wrong?
Provedor de dados: 31
Autores: Engel,   Eduardo M.R.A.; Fischer,   Ronald; Galetovic,   Alexander.
This paper reviews the Latin American experience with highway privatization during the last decade. Based on evidence from Argentina, Colombia and Chile, we find that private financing of new highways freed up fewer public resources than expected because public funds were often diverted to bail out franchise holders. Furthermore, many of the standard benefits of privatization did not materialize because of pervasive contract renegotiations. We argue that the disappointing performance of highway privatization in Latin America was due to two fundamental design flaws. First, countries followed a “privatize now, regulate later” approach. Second, most concessions were awarded as a fixed-term franchise, thereby creating a demand for guarantees and contract...

Willingness to Pay for Biodiesel in Diesel Engines: A Stochastic Double Bounded Contingent Valuation Survey
Provedor de dados: 31
Autores: Jeanty,   Pierre Wilner; Haab,   Timothy C.; Hitzhusen,   Frederick J.
The double bounded dichotomous choice format has been proven to improve efficiency in contingent valuation models. However, this format has been criticized due to lack of behavioral and statistical consistencies between the first and the second responses. In this study a split sampling methodology was used to determine whether allowing respondents to express uncertainty in the follow-up question would alleviate such inconsistencies.  Results indicate that allowing respondents to express uncertainty in the follow-up question was effective at reducing both types of inconsistencies while efficiency gain is maintained.

Using stated preferences to estimate the environmental benefits of using biodiesel fuel in diesel engines
Provedor de dados: 31
Autores: Jeanty,   Pierre Wilner; Hitzhusen,   Frederick J.
Using biodiesel fuel to reduce emissions from diesel engines is an area of increasing interest. Many environmental benefits associated with biodiesel are not traded in markets and their estimation requires economic valuation methods applied to non-market goods and services. This paper presents the results of a contingent valuation survey conducted in 2006 in two Ohio regions to estimate willingness to pay for air pollution reduction arising from using biodiesel fuel in diesel engines. The double bounded parametric formulation was used to estimate mean WTP ranging from $157 to $457. These results yield estimated aggregate benefits ranging from $123 to $429 million and can be used as a starting point for cost-benefit analysis.
