We analyze the problem of real optimal asset allocation for a pension fund maximising the expected CRRA utility of its real disposable wealth. The financial horizon of the analysis coincides with the random death time of a representative subscriber. We consider a very general setting where there exists a stochastic investment opportunity set together with stochastic contributions and pensions a...

This paper shows that, in markets with transaction costs, even if a redundant security does not even save individual investors’ total costs for their security trading, the prices of the other securities may well be different were it to not be available for trade, resulting in a different equilibrium consumption allocation. In this sense, a redundant security may give rise to the divergence of i...

Close to 30% of the US population experiences at least one mental or substance abuse disorder each year. Given the prevalence of mental health issues, this paper analyzes the role of mental health and cognitive functioning in household portfolio choice decisions. Generally, we find that households affected by mental health issues decrease investments in risky instruments. Various mental health ...

This paper investigates the price adjustment and lead-lag relations between returns on five sizebased portfolios in the Taiwan stock market. It finds evidence that the price adjustment of smallstock portfolios is not slower than that of large-stock portfolios. Additionally, limited evidence supports a positive leading role of large-stock portfolio returns over small-stock portfolio returns. The...

Retirement flexibility and inability to borrow against future labor income can significantly affect optimal consumption and investment. With voluntary retirement, there exists an optimal wealth-to-wage ratio threshold for retirement and human capital correlates negatively with the stock market even when wages have zero or slightly positive market risk exposure. Consequently, investors optimally...

This paper assesses the importance of heterogeneity in household portfolios for transmission monetary policy a New Keynesian business cycle model with uninsurable income risk and assets different liquidity. In this environment, works through investment, but redistribution lowers elasticity investment via two channels: (i) marginal propensities to invest, (ii) time variation liquidity premium. M...

this paper presents a data envelopment analysis (dea) model combined with bootstrapping to assess performance of one of the data mining algorithms. we applied a two-step process for performance productivity analysis of insurance branches within a case study. first, using a dea model, the study analyzes the productivity of eighteen decision-making units (dmus). using a malmquist index, dea deter...

Prior research debates focus on whether investors are smart enough to invest in funds that subsequently outperform. This paper documents a robust smart money effect among small fund investors who invest in the top performing funds, even after controlling for the momentum factor argued by Sapp and Tiwari (2004). I further explore the reason for the smart money effect and find that such outperfor...

We study the representative consumer’s risk attitude and efficient risk-sharing rules in a singleperiod, single-good economy in which consumers have homogeneous probabilistic beliefs but heterogeneous risk attitudes. We prove that if all consumers have convex absolute risk tolerance, so must the representative consumer. We also identify a relationship between the curvature of an individual cons...

In a finite time horizon, incomplete market, continuous-time setting with dividends and investor incomes governed by arithmetic Brownian motions, we derive closed-form solutions for the equilibrium risk-free rate and stock price for an economy with finitely many heterogeneous CARA investors and unspanned income risk. In equilibrium, the Sharpe ratio is the same as in an otherwise identical comp...
