We study the gas-water transient imbibition and drainage processes in two-dimensional nanoporous media using our recently developed Lattice Boltzmann model (LBM). To describe the microscopic molecular interactions, the model employs a pseudopotential that correlates the local density and...

This paper demonstrates the existence of adverse selection in the group insurance market with no individual choice. We provide evidence against the “conventional wisdom” that group insurance mitigates adverse selection because of the mixture of high risks and low risks. We show, however,...

In the context of insurance industry, we provide a theoretical and empirical framework to analyze the tradeoffs between three fundamental goals of business: growth, profitability, and safety. Insurers balance on premium and underwriting standards to optimize one goal constrained by the other...

Die vorliegende Dissertationsschrift besteht aus vier Kapiteln und adressiert Kernfragen in den Bereichen Versicherungstransaktionen (Teil I und IV) sowie Versicherungsbetrieb und -strategien (Teil II und III). Die aufgeworfenen Forschungsfragen sind sowohl für die akademische Forschung als...

We estimate economies of scale and scope as well as cost efficiency to explain the structure of the global reinsurance market, where large reinsurers dominate, but both diversified and specialized reinsurers play important roles. The costs and benefits of size and product diversification play...

A central matter of dispute in the internationalization literature is the existence and shape of a systematic relationship between the degree of internationalization and firm performance (I-P relationship). Considering the global insurance industry, we show that the I-P relationship depends on...

We develop a dynamic game model for efficient catastrophe risk-sharing that allows decision makers to derive optimal pricing, capital, and buying decisions in one equilibrium. Existing catastrophe insurance models focus on either the primary insurance market or the reinsurance market, thus...

We study how pension participation and expected pension benefits affect the consumption of working-age adults based on a nationally representative dataset from the China Health and Retirement Longitudinal Study during the period 2011–2015. We find that working-age adults covered by the...
