    Advantageous Innovation in the Underwriting Market for Corporate Securities

    Get PDF
    Investment banks that develop new corporate securities systematically lead the new underwriting market despite being imitated early by equally competitive rivals. We study how innovators and imitators set underwriting fees in order to identify empirically the source of this advantage. Using data of innovative securities since 1985, we do find that innovators set systematically higher fees than imitators. This premium decreases as more issues occur, and faster for later generation products. Imitation is also quicker for later generations. This evidence supports the hypothesis that the innovator has superior skills in structuring any given issue of the new security

    Future development scenarios for adaptation to climate change in the Ci Kapundung upper water catchment area, Bandung Basin, Indonesia

    Landscape change in the Ci Kapundung upper water catchment area over recent decades has increased the volume of rainfall runoff, increasing the incidence of flooding in the Bandung Basin. At the same time, climate change affects rainfall variability in Indonesia, causing higher frequencies of extreme rainfall and drought in almost all regions of the country. This study develops and assesses four scenarios for the future spatial plan in the catchment area, which is part of a research project on flood risk in the Bandung Basin. The scenarios were created based on recent land use changes within the area, current spatial policies, ecological design principles, and the geodesign framework. All scenarios were simulated using Land Change Modeler (LCM), which applies a combined cellular automata and Markov model (CA-Markov), and a multilayer perceptron (MLP) neural network, to project future landscape forms for 2030. In this simulation, the results were assessed to see the variations of land cover composition. CA-Markov models have been widely used to predict urban growth. Modeling applications for forest cover change simulation have rarely been explored. Results from LCM show that there is no significant difference in the percentages of developed areas, mixed plant communities, and conifers in 2030 in all scenarios. However, the spatial arrangement of land cover varies with each scenario. In the first scenario, for example, the disperse settlement pattern is projected to occur in the watershed in 2030, including in the areas with steep slopes and near the rivers, whereas in other scenarios, specific areas are restricted to be built. The study suggests that further analysis of hydrological impacts of each scenario is needed to ascertain which scenario can effectively reduce flood risk

    An iterative landscape planning process for sustaining flood regulation in the Ci Kapundung upper water catchment area, Bandung Basin, Indonesia

    Get PDF
    Simulations and modelling are often used in many studies to assess and visualise the effects of landscape changes on environment. However, only a few studies have been conducted to assess landscape interventions to sustain ecosystem services, including hydrological processes. This paper presents an iterative and interactive process to generate landscape planning for the Ci Kapundung upper water catchment area, Bandung Basin, Indonesia, based on two development scenarios. The land change model was coupled with a hydrological model to assess the influence of land cover changes on flood risk in Bandung Basin. The result shows that the overland flow at three observation points is affected by the land cover, topography, and soil properties. Outputs from the iterative hydrologic simulations suggested that conifers could be planted in the proposed river buffers in the case study area to reduce the volume of runoff flowing to the Ci Kapundung River
