Wastes spread to the environment negatively affect the health of humans and all other creatures. It is the responsibility of each person to assess the waste generated correctly. Recycling is an applicable option for environmental protection. This study defines university students' recycling behaviours based on the Theory of Planned Behaviour using...

Road-traffic-based air pollution accounts for one-third of the air pollution problem in Turkey. In order to combat this environmental issue and illustrate the possible direction of the road transport policy, five scenarios of withdrawing older vehicles from the fleet are analyzed using cost–benefit analysis (CBA) for 2020–2030. This article focuses...

Projections of vehicle profiles play an essential role in developing government policies for emissions reductions in the automotive sector. Determining the trends of key parameters related to tailpipe emissions is critical for analyzing the adverse effects of vehicle emissions on air quality. This study presents a framework that can be used to asse...

Government policies on renewing vehicle fleet by introducing newer, cleaner vehicles and removing old, polluting vehicles have significant impacts on air pollution. In this study, the estimated emissions of air pollutants that influence human health are reported together with health endpoints and corresponding mortality and morbidity costs under fi...

Cluster analysis is often used to determine housing submarkets. However, commonly used methods cannot handle mixed-mode data when variables of different types and units are combined. We propose new similarity measures that handle both continuous and categorical variables using normalization and discretization steps and partial match criteria. These...

Feed-in Tariff (FIT) is the long-term agreement between governments and firms investing in solar energy, where governments guarantee to purchase the energy produced by firms. This research aims to reveal the optimal FIT design for Photovoltaic (PV) investments in Turkey. Choice Experiment based questionnaire was conducted on solar energy firms to i...

Objective: International and domestic benefit transfers of the Value of a Statistical Life (VSL) are conducted and the transfer errors are examined for Turkey. Methods: For the international transfers, (1) unit-value transfer with income adjustment, (2) the method developed by ECOTEC (2001) for EU candidate counties and (3) Value of a Statistical L...

The motivations and reasons for smoking initiation, continuation, and cessation for women are different from men. This paper investigates the differences in smoking rate and intensity by gender in Turkey from 2008 to 2014. The results indicate significant differences in the decision to smoke and how much to smoke by gender. Results further indicate...

The main objective of this study is to estimate the monetary value of the gains of healthy days and life expectancy due to the ambient air quality standard that came into effect in 2014 by estimating the country-specific value of a life year (VOLY) and the value of the healthier and longer life (VHLL) for Turkey. Contingent valuation method is adop...

A contingent valuation study is conducted in three locations in Turkey using a total of 1362 observations to elicit willingness to pay (WTP) to avoid the acute respiratory illness (three days of severe coughing and throat pain). This is the first research of this kind in Turkey, and also one of a few studies conducted in developing countries. Media...

The willingness to pay (WTP) for mortality risk reduction from four causes (lung cancer, other type of cancer, respiratory disease, traffic accident) are estimated using random parameter logit model with data from choice experiment for three regions in Turkey. The value of statistical life (VSL) estimated for Afsin-Elbistan, Kutahya-Tavsanli, Ankar...

This article incorporates a political decision process into an urban land use model to predict the likely location of a public good. It fills an important gap in the literature by modeling the endogenous location of open space. The article compares open space decisions made under a majority rules voting scheme with welfare-improving criterion and f...

Organic rice production in the Philippines has been growing rapidly since 1986. We conducted a conjoint analysis to determine consumers' preferences of multiple attributes of organic rice in Manila and Naga city. Attributes included were price, reduced health risk level, environmental quality, eating quality, type of organic certification and a fai...
