Wti Crude Oil Option Implied Var And Cvar: An Empirical Application, Giovanni Barone-Adesi, Marinela Adriana Finta, Chiara Legnazzi, Carlo Sala Sep 2019

Wti Crude Oil Option Implied Var And Cvar: An Empirical Application, Giovanni Barone-Adesi, Marinela Adriana Finta, Chiara Legnazzi, Carlo Sala

Using option market data we derive naturally forward-looking, non-parametric and model-free risk estimates, three desired characteristics hardly obtainable using historical returns. The option-implied measures are only based on the first derivative of the option price with respect to the strike price, bypassing the difficult task of estimating the tail of the return distribution. We estimate and backtest the 1%, 2.5%, and 5% WTI crude oil futures option-implied value at risk and conditional value at risk for the turbulent years 2011–2016 and for both tails of the distribution. Compared with risk estimations based on the filtered historical simulation methodology, our results …


Crop Planning In Sustainable Agriculture: Dynamic Farmland Allocation In The Presence Of Crop Rotation Benefits, Onur Boyabatli, Javad Nasiry, Yangfang (Helen) Zhou May 2019

Crop Planning In Sustainable Agriculture: Dynamic Farmland Allocation In The Presence Of Crop Rotation Benefits, Onur Boyabatli, Javad Nasiry, Yangfang (Helen) Zhou

This paper examines crop planning decision in sustainable agriculture---that is, how to allocate farmland among multiple crops in each growing season when the crops have rotation benefits across growing seasons. We consider a farmer who periodically allocates the farmland between two crops in the presence of revenue uncertainty where revenue is stochastically larger and farming cost is lower when a crop is grown on rotated farmland (where the other crop was grown in the previous season). We characterize the optimal dynamic farmland allocation policy and perform sensitivity analysis to investigate how revenue uncertainty of each crop affects the farmer's optimal …

We examine the impact of rural electrification on individuals and businesses within a community in order to test a resource-based theory of entrepreneurship. We show that access to electricity increases average households’ income and entrepreneurial activities. The impact of electricity on entrepreneurial activity has wide-ranging implications for development policy in countries where access to electricity is sparse. Results show a significant difference in entrepreneurial opportunities with respect to firm formation, with the electrified site reporting more new micro-enterprises than the control site after implementation. Electrification affects both households’ income, individuals’ perceptions of their social position, and opportunities for business development. …


Corn, Soybeans Or Fallow: Dynamic Farmland Allocation Under Uncertainty, Onur Boyabatli, Javad Nasiry, Yangfang (Helen) Zhou Mar 2019

Corn, Soybeans Or Fallow: Dynamic Farmland Allocation Under Uncertainty, Onur Boyabatli, Javad Nasiry, Yangfang (Helen) Zhou

Research Collection Lee Kong Chian School Of Business

This chapter develops a theoretical basis for understanding the trade-offs facing a farmer for allocating his farmland among several crops over multiple growing seasons. Specifically, we focus on the farmland allocation among two cash crops (corn and soybeans) and letting the farmland lay fallow to rejuvenate the soil and increase the revenue for the crop grown on this farmland in the subsequent seasons. In each growing period, the farmer chooses the allocation in the presence of revenue uncertainty for each cash crop, and crop rotation benefits across periods, where revenue is stochastically larger and farming cost is lower when a …


The Impact Of An Electrical Mini-Grid On The Development Of A Rural Community In Kenya, Abubakr Bahaj, Luke Blunden, Christopher Kanani, Patrick James, Issac Kiva, Zoe Matthews, Heather Price, Hildah Essendi, Jane Ealkingham, Gerard George Feb 2019

Electrical mini-grids can provide electrification to rural communities far from the national network. However the benefits of such schemes are disputed. We observed changes in two matched trading-centres in Makueni County, Kenya, neither of which were initially electrified. During the study a solar photovoltaic mini-grid scheme (13.5 kWp) was constructed in one of the trading-centres. After electrification there were relative increases in the number of businesses and business income. Comparing the households in the areas around the trading centres, perceived wealth increased more around the electrified trading centre. Qualitative interviews indicated improvements in service provision by the local school and …


Volatility Spillovers Among Oil And Stock Markets In The Us And Saudi Arabia, Marinela Adriana Finta, Bart Frijns, Alireza Tourani-Rad Jan 2019

Volatility Spillovers Among Oil And Stock Markets In The Us And Saudi Arabia, Marinela Adriana Finta, Bart Frijns, Alireza Tourani-Rad

In this article, we use high frequency data and an identification via changes in volatility approach to assess the volatility spillovers among oil and the US and Saudi Arabian stock markets. We document the existence of asymmetry in contemporaneous spillover effects. Particularly, during the times when oil’s trading hours overlap with the US and Saudi Arabian stock markets, the volatility spillover from oil to the stock markets is higher than the other way around. We highlight the importance of taking into consideration the information present during continuous trading hours of oil, especially during simultaneous trading hours with the stock markets. …
