urban transport policy. which will be expressed in the fafe level, fare structure, and method of fare
cOllection. In fact, the cu rrent practice of fare determination results in much controversy from operators and
users, for example in Indonesia. The main problem focuses on the different perceptions regarding 'the suitable farc' for all stakeholders. This 3r1icle aims to compare the user perception of willingness and ability [Q pay for paratransit. The data were collected from a survey in Bandung. Indonesia. and analyzed using sUHistical analyses. The findings illustrate a gap between the values of willingness and ability, and also reveal that peop le ditferenl valuations regarding the ir related perceptions_ This study also discusses the policy

INTRODUCTION In economics, the consum er's willingness to pay (WTP) means the maximum amo unt that a person woul d be willing to pay for n service rather than do without it (A IGhuraiz and Enshassi, 2005), or wou ld give up in order to enjoy an improvement in qual ity (W hitehead, 2005). The WTP concept is useful in visualizing the viewpoint of users of a system (Khisty and Lall , 2003) and as the key com ponent of the benefit-<:ost evaluation (Hoehn and Krieger, 2000; AI-Ghuraiz and Enshassi, 2004). Further. a positive WTP indicates not only a positive attitude to the thing valued, but also has the advantage of indicating the strength of that attitude constrained by factors such as an ability to pay (Jones-Lee, 1993; Wa lton et ai, 2004). Meanwhile, the ability to pay (ATP) princip le, bes ide the benefits princ iple, is one of the normati ve approaches underlying th e theory of taxation (see e.g. Musgrave and Musgrave, 1975; Deb et ai, 2003). The ATP principle meanS that for a pu blic project, those who are able lO affo rd to pay more should pay more. The most popular var iant of the ATP principle is ca lled the equal marginal sacrifice principle (Musgrave and Musgrave, 1975). A usual assumption is that individua ls who declare them selves wi lling to pay the price should, somehm\, be able to do so (Russell. 1996; Mataria et a i, 2006). In fact, as Senbil and Kitamura (2004) stated, individuals are Jptto report values below the real va lue that can be paid, because they might feel them se lves more comfortable by leaving a gap that mi ght be traversed in the case of increased risk, and they mi ght gradually increase the value or sudden ly swilch to the real WTP when their reported values turns out to be of no use. Thus, the rel alionship between WTP and ATP remains a matter of debate. Some economists argue that the two notions should be strongly distinguished (Mataria et a i,
2006).

the hunran dec is ion-n.raking process, emphasizing the accumulation of evidence regarding the disparities in the measures ofvalues (see Knetsch and Sinden, 198'1; Loomes et al. 2006: and Sugdcn, 2003 ior n.rore discussion regarding this topic). Sugdc-n (2005) statcs that thc prelerences that govern people's actual behavior are otien incoherent and unstable. Indeed, psl,chologists have shown that people olten treat gains and losses aslmmetricall), and tend to rcquire a substantially larger increase in rvealth to compensate lor a loss than tlre :rrroLrnt thcl rvould be willing to pay for an equivalent gain (Guria et al, 2005).

Payments might be made at considerable social cost. obliging the Person to give up essential consuulption such as education, just to bc able to acquire the service (Mataria et al, 2006). Indeed, when confronted u,ith a sevcre social and,/or economic exogenous shock, such as rapid impoverishment, individuals may begin a process of re-prioritization of what is important and what is not. leading them ro underestimate issues in which they were previously expressing relative interesr (Mataria et al. 2006). Lr these situations the role of ATP bccornes clcar, u'hich underlines the d il'lcrence bctrvce rr WTP and ATP. Indeed, it seeurs fair, even for the poor, to give a high value of W IP lor good scrvices, even though they are unaffordable: as Ajzen et al (2000) and Walton et al (2004) have stated, WTP values are based on psychologically considerations. Also, it seems tair for the poor to express a very low ATP, even for very good services, since ATP is defincd as the real allocation or sharing from his/her income in order to buy the service, rr,,h ich lirrits the capability to buy that service. It is highly possible that someone shows a high \l'lP uhile sinrultancously showing a lorl ATP. This means that the poor have a high appreciation tbr thc services that are too expensive ibr them to allord. This is a possiblc situatiorr for' 'captive riders, especialll thc poor. In the case of hiqh incontc (generally 'choice ) riders rneeting an unsatist'actorv or lorv service quality, they * ill be highll' likcll to have a verl lou WTP, although in fact thcl have a high ATP.

The monthly expenses of the users ranged {iom less than 0.5 million IDR (58.69'0), 0.5 I million IDR (30.4%), to more than 1 million IDR ( I 1%). The transportation expenses per month were less than 100,000 IDR (62%) and 100,000 IDR or more (38uui,). The distribution of the number of tnps using paratransit per day was once (13.(r%). twice (63.2ok), and three or more times per day (23.20/,,). The trip length in making use of paratransit was less than 5 km (18.3%),5-10 km (41.8%), l0-20 krn (23.2%), and morc than 20km (10.1%). The u,aiting t ime r ange d from 1 ess than5 minutes (41 .7%),5 1{\ minutes (34.5%), l0-15 minutes (11%), to more than l5 minutes (7.2%).
The users perceived accessibility as easy (60.9%) and fair (35.9%), while 21.2% and 72.8Yo perceived paratransit as comfortable and fair, respectively. While 19.4Y" of the respondents s tated that p aratransit was safe, the perceived service quality of paratransit ranged from very bad (5.5%), and bad (20%), to far ('10.7%). The suncy yielded the result that'16.8o/,' of the respondents agreed with a fare increment when therc is an inrprovement in scrvice quality, with the agreed fare increment as less than 500 IDR (45.3%,) and 500 IDR or more (54.7%). It is useful to know whether there is a difference betwecn the value of WTP and ATP, and between the value based on quality perception and financial perception. The result of the paired t-test shows that the WTPq (WTP based on quality perccption) is significantly higher than ATPq (ATP based on quality perception), where thc H6 : WTPq ATPq = 0 is rejected (p-value - .016) with H" : WTPq-ATPq > 0. This result explains that people tend to express a higher value of u,illingness than their ability when they relate the valuation with the quality perception. The value of WTPf (WTP based on financial perception) is significantly smaller than ATPf (ATP based on financial perception), which is shown by the rejection of H6 : WTPf ATPf : 0 (p-value : .000) with H" : WTPf-ATPf < 0. The result illustrates that people tend to express a lower willingness than their ability rvhen they relate the valuation with the financial perception. In addition, the paired t-test also shows that thc value of WTPq is significantly different from WTPI and the value of ATPq is sigrrificantly dlffcrent fiom ATPf. This is shown by the rejection (p-value : .000) of H6 : WTPq = WTPI, and also H6 : ATPq = ATPf. Further analysis employs a cross-tabulation of ATP and WTP. Table I explains the relationship between WATP values and several aspects of service quality, namely accessibility, comfort, safety, and overall quality. Since there are different pcrceptions regarding the service quality, from very good up to very bad, then it is intercsting to know whether there is any difference in WATP for groups of users who perceive the service quality as bad, and users who pcrceive it as good. Thus, the null hypothesis (H6) is that the value of WATP is independent of the service quality perception. The chi square test is employed to test the independence as the null hypothesis (Ott and Longnecker, 2001). As can be seen in Table l , the chi-squarc test shows that the values of A IP and W'l'P based on quality perception are independcnt of the service quality categories (p > .01). This means that there is no difference in A",WTP based on the differcnt perceptions of service quality. The possible reason for this is that the paratransit's service quality was perccivcd similarly, so the users only show a naro\\ range of W/ATP.
