BACKGROUND In cost-effectiveness analysis, discount rates are used in calculating the value of future costs and benefits. However, standard discount rates may not accurately describe the decision-making of patients with ulcerative colitis (UC). These patients often choose the long-term risks of immunosuppressive therapy over the short-term risks of colectomy, demonstrating very high discount ra...

This paper offers a market microstructure based model to explain the well-documented diversification discount. While explicitly assuming that stock price conveys valuable information to the management, our model shows that the value loss from diversification is a function of the stock price informativeness. If more investors are willing to follow and actively trade a certain stock, more informa...

In this paper, I examine how time-varying discount factors can contribute to labor market volatility in a Diamond-Mortensen-Pissarides matching model. I find that the procyclical discount factor of either entrepreneurs or workers can magnify labor market volatility. Quantitatively, the entrepreneur’s discount factor has a larger effect than the worker’s discount factor. To account for the obser...

de Kok et al. (1) recently reported the cost-effectiveness of human papillomavirus vaccination in the netherlands and argued that human papillomavirus vaccination is not a cost-effective preventive measure in the netherlands. They calculated a discounted (annual rate 3%) incremental cost-effectiveness ratio (IcER) of €53 500 per qualityadjusted life-year (Qaly), which is clearly higher than the...

We investigate an automobile supply chain where a manufacturer and a retailer serve heterogeneous consumers with electric vehicles (EVs) under a government’s price-discount incentive scheme that involves a price discount rate and a subsidy ceiling. We show that the subsidy ceiling is more effective in influencing the optimal wholesale pricing decision of the manufacturer with a higher unit prod...

We estimate discount rates of 555 subjects using a laboratory task and find that these individual discount rates predict inter-individual variation in field behaviors (e.g., exercise, BMI, smoking). The correlation between the discount rate and each field behavior is small: none exceeds 0.28 and many are near 0. However, the discount rate has at least as much predictive power as any variable in...

A mathematical formalism is developed for the existence of unique invariants associated with wide classes of observed discounting behavior. These invariants are ‘exponential discount rate spectra,’ derived from the theory of completely monotone functions. Exponential discounting, the empirically important case of hyperbolic discounting, and so-called sub-additive discounting are each special ca...

I explore methods that characterize model-based valuation of stochastically growing cash flows. Following previous research, I use stochastic discount factors as a convenient device to depict asset values. I extend that literature by focusing on the impact of compounding these discount factors over alternative investment horizons. In modeling cash flows, I also incorporate stochastic growth fac...
