An upper bound used in consolidating input-output models is shown to be non-minimal, and thus non-optimal. The least upper bound is then obtained. Non-least upper bounds are shown to be useful only when complemented by corresponding lower ones. 相似文献

This study analyzes the impact of economic, financial, and political instability on the liquidity transformation of banks operating in unstable environments. Our main goal is to assess the relationship between overall risk in a country and liquidity transformation. With this goal in mind, we use a sample of five Middle Eastern countries during the period 2005–2010. Our results showed that the high-risk environment has a significant and negative impact on both liquidity transformation and the extension of credit. In addition, we conclude that high capital requirements may reduce further lending, while imposing liquidity requirements seems to be a better strategy for enhancing liquidity transformation. 相似文献

This article proposes a bivariate lattice model for evaluating equity-linked policies embedding a surrender option when the underlying equity dynamics is described by a geometric Brownian motion with stochastic interest rate. The main advantage of the model stays in that the original processes for the reference fund and the interest rate are directly discretized by means of lattice approximations, without resorting to any additional transformation. Then, the arising lattices are combined in order to establish a bivariate tree where equity-linked policy premiums are computed by discounting the policy payoff over the lattice branches, and allowing early exercise at each premium payment date to model the surrender decision. 相似文献

We analyze the effect of a large group on a public goods model with lotteries. We show that as populations get large, and with preferences in which people only care about their private consumptions and the total supply of the public good, the level of contributions converges to the one given by voluntary contributions. With altruistic preferences of the warm-glow type, the contributions converge to a level strictly higher than those given by voluntary contributions, but in general they do not yield first-best levels. Our results are important to clarify why in general governments do not rely on lotteries for a large part of the revenue creation for public good provision. They are also useful to understand why lottery proceeds are earmarked to worthy causes, where warm glow is likely to be larger. 相似文献

Abstract This article investigates how price and brand loyalty of three frequently purchased product categories can influence the purchase decision process of store brands versus national brands. A multinomial logit model was constructed to analyse the data obtained from a consumer panel. The results confirmed that brand loyalty is the main variable which influences the purchase decision process of both national and store brands. The influence of price on the purchase decision process is product specific. There is a clear distinction between the buyer's profile of store brands and national brands. But there is no evidence of any correlation between demographic variables and national brands or store brands. 相似文献

This paper investigates the performance of size- and value-based strategies in the Italian stock market in the period 2000–2018. Previous research argued the impossibility to define properly value-sorted portfolios due to the inaccuracy of book-to-market ratios available for Italian listed stocks. Using more accurate data, we implement portfolios sorting based on value and growth stocks, to assess the relevance of the value factor in the Italian stock market. We find that the capital asset pricing model fails to explain the cross-section of returns on the different strategies while the Fama and French three-factor model provides a better fit. The results show that all three factors are significant in explaining Italian stock returns during the sample period. Unlike previous studies, which either found no value effect at all or no clear-cut results when testing the book-to-market variable, we find that the value factor is statistically significant and the associated risk premium is of a considerable size. 相似文献
