the political economy of deforestation in the Tropics
Research Papers in Economics, 2012Co-Authors: Robin Burgess, M C Hansen, Benjamin A Olken, Peter Potapov, Stefanie SieberAbstract:Tropical deforestation accounts for almost one- fifth of greenhouse gas emissions worldwide and threatens the worlds most diverse ecosystems. The prevalence of illegal forest extraction in the Tropics suggests that understanding the incentives of local bureaucrats and politicians who enforce forest policy may be critical to combating tropical deforestation. We find support for this thesis using a novel satellite-based dataset that tracks annual changes in forest cover across eight years of institutional change in post-Soeharto Indonesia. Increases in the numbers of political jurisdictions are associated with increased deforestation and with lower prices in local wood markets, consistent with a model of Cournot competition between jurisdictions. We also show that illegal logging and rents from unevenly distributed oil and gas revenues are short run substitutes, but this effect disappears over time as political turnover occurs. The results illustrate how incentives faced by local government officials affect deforestation,and provide an example of how standard economic theories can explain illegal behavior.

thermal comfort in classrooms in the Tropics
Energy and Buildings, 2003Co-Authors: Nyuk Hien Wong, Shan Shan KhooAbstract:Abstract A field study was conducted in classrooms in Singapore, which were mechanically ventilated by fans, to assess their thermal conditions during the students’ lesson hours. Thermal comfort variables were measured at the same time when students and teachers answered a survey on their perception/sensation of the indoor climate. Objective data analysis showed that none of the classes had thermal conditions falling within the comfort zone of ASHRAE standard 55. Occupants found temperature range beyond the comfort zone acceptable. This suggests that the standard is not applicable in free-running buildings in the local climate. A new PMV model, which incorporates two common forms of adaptation-reducing activity pace and expectation, still showed discrepancy in predicting actual thermal sensations, especially at lower temperatures. Comparison of the various methods of assessing thermal acceptability showed that they produce widely disparate results, with the Bedford scale giving the highest level of acceptability. Classroom occupants generally accepted cool thermal sensations more readily than warm thermal sensations.

Parameterization Studies of Solar Chimneys in the Tropics
Energies, 2013Co-Authors: Alex Yong Kwang Tan, Nyuk Hien WongAbstract:Abstract: The paper examines the effect of the solar chimney’s stack height, depth, width and inlet position on the interior performance (air temperature and speed at 1.20 m height above the ground) as well as proposes an optimal tropical solar chimney design. Simulations show that the output air temperature remains constant while the solar chimney’s width is the most significant factor influencing output air speed. The solar chimney’s inlet position has limited influence on the output air speed although regions near the solar chimney’s inlet show an increase in air speed. Furthermore, a regression model is developed based on the solar chimney’s stack height, depth and width to predict the interior air speed. To optimize solar chimney in the Tropics, the recommendation is to first maximize its width as the interior’s width, while allowing its stack height to be the building’s height. Lastly, the solar chimney’s depth is determined from the regression model by allocating the required interior air speed.
