We show that an equilibrium always exists in the Rothschild-Stiglitz insurance market model with adverse selection when insurers can o¤er either nonparticipating or participating policies, i.e. insurance contracts which may involve policy dividends or supplementary calls for premium. The equilibrium allocation coincides with the Miyazaki-Spence-Wilson equilibrium allocation, which may involve c...

Authors present the stock price prediction algorithm by using Bayesian network. The present algorithm uses the network twice. First, the network is determined from the daily stock price and then, it is applied for predicting the daily stock price which was already observed. The prediction error is evaluated from the daily stock price and its prediction. Second, the network is determined again f...

BACKGROUND AND OBJECTIVES Adjusted for inflation, household income has been relatively flat since the mid-1990s, but the inflation rate of employer-sponsored health insurance has been greater than both household income growth and general inflation for 50 years. We estimated the effect on average family income if health insurance inflation matched the general inflation rate since 1996, and those...

Stock price prediction is an important and challenging problem for studying financial markets. Existing studies are mainly based on the time series of stock price or the operation performance of listed company. In this paper, we propose to predict stock price based on investors' trading behavior. For each stock, we characterize the daily trading relationship among its investors using a trading ...

We develop a simple model in which the presence of portfolio insurers in a market of risk-averse traders leads to multiple equilibria for the pricing of financial assets and can cause an increase in volatility, including insurance-induced price drops. We demonstrate, however, that centralized portfolio insurance firms may actually reduce, not increase, volatility, even if the existence of these...
