The interplay between risk adjustment and risk rating in voluntary health insurance

Many regulated health insurance markets include risk adjustment (aka risk equalization) to mitigate selection incentives for insurers. Empirical studies on the design and evaluation of risk-adjustment algorithms typically focus on mandatory health insurance schemes. This paper considers risk adjustment in the context of voluntary health insurance, as found in Chile, Ireland, and Australia. In addition to the challenge of mitigating selection by insurers, regulators of these voluntary schemes have to deal with selection by consumers in and out of the market. A strategy for mitigating selection by consumers is to apply some form of risk rating. Our paper shows how risk adjustment and risk rating interact: (1) risk rating reduces the need for risk adjustment and (2) risk adjustment reduces premium variation across rating factors, thereby increasing incentives for consumers to select in and out of the market.     

Understanding short-term price pressure from index reconstitutions: Evidence from the CSI 300

Motivated by the mixed results of the few prior studies, we focus on the short-term price performance of stocks added to or deleted from the CSI 300 Index. Consistent with the price pressure hypothesis, we evidence a temporary change in the prices of respective added and deleted stocks, followed by subsequent price reversions. To reconcile past studies, we also test several explanatory factors as potential sources of short-term price pressure. Results show that changes in investor trading behaviour, investor awareness, firm risk, and liquidity explain the short-term price pressure of added and deleted stocks, while changes in institutional trading, realised volatility, and liquidity explain the differences in the impact of reconstitutions between added and deleted stocks.     

Speculative trading preferences of retail investor birth cohorts

This study examines the effect of investor birth cohorts on speculative investment preferences. Using retail trading and portfolio data from Finland over two decades, we find that individuals who have experienced desirable macro-economic and social conditions during adolescence, such as high gross domestic product (GDP) growth and low divorce rates, are more likely to invest in speculative stocks. A positive relation is found between the proportion of speculative-prone cohorts in the stock market and returns of stocks of lottery nature. We provide new evidence on the adverse effect of speculative investments, finding that cohorts with higher speculative investment weights on their portfolios achieve lower absolute and risk-adjusted returns. We also provide support for earlier research that identifies a positive association between recent portfolio performance and the propensity to invest in speculative stocks.
