Abstract

The research was carried out because the researcher found indications of low level of employment satisfaction among the staff, an organizational culture in the service that is not fully conducive, unclear and limited career development paths and a fairly low degree of staff competence. The aim of the study is to test and analyze the impact of employment education, organization culture, careers and competences on employment satisfaction of employees on the workforce and mobility of the population. As for the research method used, it is a quantitative type associative method with a dual linear regression model. The research results show that the job training variable has a partial effect on job satisfaction, while organizational culture, career development and competence have no effect. Meanwhile, simultaneously the variables of job training, organizational culture, career development and competence influence job satisfaction. Keywords : Job Training, Organizational Culture, Career Development, Competency, and Job Satisfaction

Abstract

One way to minimize risks due to uncertainty in stock price movements is by using derivative products, one of which is an option. Binary options, a type of exotic option, provide a fixed payout if certain conditions are met at maturity, but are difficult to solve analytically. In this study, we utilize binomial and trinomial lattice methods, specifically the Cox-Ross-Rubinstein Binomial, Hull-White Trinomial, and Kamrad-Ritchken Trinomial models, to determine the price of binary options. Results indicate that all three methods converge towards the exact solution, demonstrating their applicability for pricing binary options, with the Kamrad-Ritchken Trinomial method showing superior accuracy due to the lowest mean relative error. Additionally, we analyze factors influencing binary option prices, including initial price, strike price, maturity time, volatility, and risk-free interest rate. The study’s originality lies in the comparative analysis of these methods under the same market conditions. However, limitations include model assumptions and potential data variability that may affect generalizability. Future research could extend these methods to various stock data or other financial instruments to test robustness. This research provides insights into optimal lattice method selection for practitioners in binary option pricing.
