Santiago de Compostela, Santiago de Compostela, Spain. Hybrid electric vehicles HEVs could be a good short term option to help achieve global targets regarding road transport greenhouse gas emissions. Several common and country-specific public policies based on price or tax rebates are established in order to encourage baremw adoption of HEVs.

The present research empirically assesses market preferences for 20009 in Spain, looking at the role of subsidies. Therefore, current levels of economic subsidies applied in isolation to promote these types of vehicles may have a quite limited effect in extending their use. Overall, it is found that drivers have clear misconceptions about HEVs, which affect their purchasing choices and perceptions.

Therefore, a policy mix of various incentives including informational campaigns may be required in order to stimulate the demand for HEVs. In Decembera total of countries ratified a universal agreement to combat climate change at the Climate Summit in Paris COP 21where they expressed their willingness to move together towards a low carbon economy. Despite a slight decrease in the last few years, these emissions are still The consequences of air pollutants generated by the transport sector on human health are an increasing cause for concern.

According to the European Commission [ 3 ], air pollution causes the premature death of more thanpeople in Europe every year. While in United States, Chinese, and Japanese, the new registrations in the same year were dominated by gasoline vehicles [ 4 ]. In particular, Italy However, the growth rate of the AFV new registrations was very low in most member bxreme. The rise of the AFV diffusion is due to several factors, including the availability of a wide range of models in the market, but also in part to different government incentives based on direct rebates in purchase prices, tax reductions, free parking, and access to priority lanes, among others [ 5 ].

Among the three models, HEVs are the most sold in EU, being the highest sales in those registered in the Netherlands baremd. This study explores the potential reasons behind such a low adoption rate.

It uses braking energy, which is normally wasted, to recharge the battery. HEVs offer economic and environmental advantages over conventional cars, ceteris paribus. The engineering literature has produced very relevant references providing accurate and technical information about the advantages in terms of current efficiency, environmental performance and future possibilities of HEVs.

Why is the market for hybrid electric vehicles (HEVs) moving slowly?

Vareme general, HEVs are cheaper than EVs and PHEVs; they do not suffer from battery problems or lack of infrastructures, and benefit from public incentives in many countries. Therefore, they should be very competitive with respect to diesel and gasoline vehicles. It has not been clear why drivers have avoided switching to HEVs. Is it primarily related to their price? And if so, what types of incentives are needed to encourage drivers to switch to HEVs?

Or is it based on other misconceptions and concerns associated with HEVs that may be more important than the price markup?

Based on a discrete choice experiment DCE included in an extensive online questionnaire, the present paper aims to provide some insight into these questions, as well as the type of incentives that are required in order to galvanize the HEV market.

Specifically, it explores preferences towards car attributes, including fuel consumption and CO2 emissions improved in HEVs. Finally, individual heterogeneity in preferences for car attributes, including the price—a factor that is often overlooked—is considered by specifying a random parameter logit RPL model. The results detected heterogeneous individual perceptions for different AFVs, with conventional cars remaining the most attractive option.


They showed that people were sensitive to fuel efficiency, but were more sensitive towards horsepower and weight. The present research joins this line of studies by adding a number of contributions. First, it assesses the heterogeneity of preferences towards car attributes across drivers. Second, this study investigates the importance of incentives when buying efficient cars, and explores whether these incentives increase the demand for HEVs.

Third, results are contextualized in the current market conditions. The present research was conducted in Spain.

The current economic crisis has resulted in the Spanish vehicle fleet being one of the oldest in Europe, currently with an average car age of Driving vehicles of this kind multiplies the environmental damage caused by road transport.

In this context, various strategies have been promoted in Spain, including the Movele and the Pive public programs, both aimed at promoting the market adoption of efficient cars. As a result of bateme program, the Institute for the Diversification and Energy Saving IDAE estimated that from to the Pive plan has led to the replacement ofold vehicles, saved million liters of fuel per year, and reduced baremw gas emissions bytons of CO2 per year [ 22 ].

In spite of these current public policy efforts to encourage drivers to adopt HEVs, these are still not particularly popular in the Spanish market. InBaremr only accounted for 2.

Data from drivers were collected using an online survey directed to a representative sample of drivers over the age of eighteen. The survey was administered to 1, residents in Spain. The number of fully completed and useful questionnaires was 1, The survey asked drivers to provide information about several car related issues, including current car s ownership, brand preferences, awareness of energy consumption issues, and their environmental attitudes.

Next, the survey provided information about HEVs, asking about their intentions and plans for future car-purchases, including a DCE to elicit preferences to buy a future car. It concluded with the socio-demographic characteristics of the driver.

Participants were asked about what size small, medium or large they would prefer to have their next car? And thanks to the interactive aspect of the questionnaire, this information was received immediately, and automatically, depending on their answer, they were assigned to one of the two possible versions of the DCE survey. In particular, one was designed for drivers interested in buying small or medium-sized cars and the other for those who were willing to buy large cars.

A total of drivers The survey questions were common to the participants. The only difference between the two versions was the levels of the attributes included in the DCE. In this paper, data from the survey completed by those drivers willing to buy a small and medium-size car are analyzed. A DCE is used as it is the more appropriate way for measuring consumer welfare, and its results are more consistent with the economic theory than a traditional conjoint analysis [ 24 ].

In addition, HEVs have a small market share, and revealed preference data sources are still scarce.

The DCE method is based on the assumptions of economic rationality and utility maximization [ 24 ]. It consists of presenting drivers barrme several car alternatives, and asking them to choose one of them based on their preferences. Moreover, the utility derived from an alternative is assumed to depend on the marginal utilities associated with its attributes [ 25 ].

As a HEV is a quasi-public good, both economic attributes and environmental non-economic attributes are included. In the survey, and prior to the DCE exercise, participants were familiarized with HEVs and the expected consumption and emissions for a mid-size car. They were also required to assume that all non-specified attributes remained constant across alternatives. A DCE was then carried out, in which the participants could select between a regular vehicle and a HEV, or just remain with the status quo option neither car.

Focus groups, pilot baremr and previous studies were used in order to identify the most relevant attributes and suitable levels for our DCE exercise. Previous studies [ 13 ] summarized the determinant factors of a car choice process mainly into economic attributes purchase price, fuel cost baareme, non-economic attributes refueling or recharging time, availability of fuel or recharging opportunities, technological performanceand environmental attributes emissions.

Besides the type of vehicle, two 0209 attributes have been included: Apart from the monetary attributes, each choice set included two non-monetary or environmental attributes.

The environmental attributes included were carbon dioxide Barmee emissions, which were found to be significant in earlier studies [ 13 ], and the option of biofuel adaptation flex-fuelwhich is a recent trend in carmakers. Some existing studies [ 1027 ] have explored preferences for biofuel cars, although it has never been investigated as vareme additional attribute to conventional and HEVs.


The attribute levels are based on information obtained from car suppliers in the Spanish market for small and midsize cars. This information is used to determine 2 levels of vehicle type regular or HEV and 3 levels of prices used in the analysis: The mid-price level considered corresponds to the average price of new cars sold in Spain in 22009 Similarly, the CO2 emissions were expressed as grams of CO2 per kilometer [ 1028 ].

Again, for simplicity, and for the purposes of this research, only two emission levels are included: Finally, the presence or absence of the potential of biofuel adaptation corresponded with the two dichotomous levels specified for the corresponding attribute. The OOD is constructed so as to maximize the differences in the attribute levels across alternatives, and therefore, maximize the information from each respondent, forcing the tradeoffs of all attributes in the experiment [ 30 ].

It should note that this design fits best choices where each alternative has the same number of attributes, and each attribute has the same number of levels. Each respondent was presented with a total of 8 choice cards, a reasonable number that does not uppc data quality [ 31 ].

Fig 1 shows an example of a choice card. The no-choice alternative neither car was provided in order to make the choice decisions very similar to market decisions or more realistic. Assuming utility maximizing behavior, the empirical applications based on discrete choice models make possible to estimate nareme probability that an individual chooses a given car alternative, among a set of available alternatives. The MNL probability of choosing an alternative a among braeme set of J alternatives is given by [ 3233 ]:.

The MNL imposes homogeneity in tastes, inflexible substitution patterns in preferences between different alternatives and independence in unobserved factors over time [ 35 ]. The RPL model probability unconditional probability is the integral of the conditional probability over all the random parameters [ 3233 ]:.

In bwreme same line as previous studies [ 103712 ], positive preferences for these attributes are not allowed, as it is not expected that people would prefer higher prices, higher fuel consumptions or higher CO2 emissions.

Several distributions normal, log-normal, uniform, triangular, etc. Thus, it is considered as a nonrandom parameter. This valuation exercise also aims to predict respondents choices between the two car-alternatives conventional, and HEVs and the no-car option neither A or Bincluding in the DCE models a no-choice-specific constant ASCdenoting the election of the status quo option.

It is assumed that the no-choice-specific constant follow a normal distribution because drivers may like or dislike staying or not with their current cars. In addition, it explores how preferences for the no-car option, compared to the car options, shift with the following socioeconomic variables: It also analyzes the heterogeneity in preferences for the no-car option among drivers who reported that incentives such as direct subsidies SUBSIDY would be important factors when buying an efficient car.

Furthermore, and after the vector of parameters is obtained, the WTP welfare measures are calculated in order to determine the monetary equivalent of the marginal utilities placed by drivers in each car attribute improvement. This step may provide important information to policy makers regarding the economic efforts that people are willing to make to acquire HEVs and some improvements in car attributes. In a RPL model, when the numerator and the denominator included in Eq 4 are random, the expression of the WTP ratio shown in Eq 4 becomes a randomly distributed term.

In this case, Daly et al. In the present application, WTP measures are constructed based on unconditional parameter estimates [ 39 ], because they allow for prediction outside of the sample, unlike 20009 parameter estimates, which only predict within the sample [ 40 ].

Deriving Baerme based on unconditional parameter estimates requires the population to be simulated [ 39 ]. Both, numerator and denominator of 4 have been simulated employing random draws coming from the log-normal distributions defined by the estimated parameters.
