In this thesis we define a Hawkes process with exponential decay that later on is used in an application to insurance. We have also applied a simulation algorithm for the Hawkes process that are able to model cluster arrival of claims. In the classical risk model one uses a homogeneous Poisson process to model the arrival of claims which is not realistic. What is most crucial for an insurance c...

In this study, a fuzzy-stochastic-based violation analysis (FSVA) approach is developed for the planning of water resources management systems with uncertain information, based on a multistage fuzzy-stochastic integer programming (FSIP) model. In FSVA, a number of violation variables for the objective and constraints are allowed, such that in-depth analyses of tradeoffs among economic objective...

We derive bounds on the ratios of deadweight loss and consumer surplus to producer surplus under Cournot competition. To do so, we introduce a parameterization of the degree of curvature of market demand using the parallel concepts of ρ-concavity and ρ-convexity. The ”more concave” is demand, the larger the share of producer surplus in overall surplus, the smaller is consumer surplus relative t...

We examine the impact of multiproduct nonlinear pricing on profit, consumer surplus and welfare in a duopoly. When consumers buy all their products from one firm (the one-stop shopping model), nonlinear pricing leads to higher profit and welfare, but usually lower consumer surplus, than linear pricing. By contrast, in a unit-demand model where consumers may buy one product from one firm and ano...

abstract the purpose of this paper is to investigate the factors affecting adoption of agricultural crops insurance among apple growers in semirom and eghlid shahrestans and determining the best model. a survey was conducted using the stratified random sampling. data were collected by questionnaire from 240 adopters and 157 non – adopters. the results showed that adopters of insurance are more ...

We construct a growth model consistent with China’s economic transition: high output growth, sustained returns on capital, reallocation within the manufacturing sector, and a large trade surplus. Entrepreneurial firms use more productive technologies, but due to financial imperfections they must finance investments through internal savings. State-owned firms have low productivity but survive be...
