This article proposes a novel valuation model, growth and value hybrid model, to estimate the stock price. This proposed model combines the essence of the asset-based approach, the income-based approach, and the principle of mean reversion to develop the theoretical closed-form formula consisting of three coefficients: value coefficient, value support coefficient and growth coefficient. Regression analysis is employed to fit market data to determine these coefficients. Moreover, this study proposes the double sorting method to build the quantile regression models of the formula to estimate the stock price at a specific quantile. The results show that the predictive capability of the hybrid valuation model is superior to the model without using value support coefficient, which supports the assumption that the PBR is not associated with the ROE when the ROE is less than a threshold. In different time periods of the stock market, no significant difference exists on the value support coefficient. However, the variations of the value coefficient and the growth coefficient are significant.  相似文献

This study investigates the structural effect of tourism on alleviating the urban-rural dichotomy and the moderating effect of a dual urban-rural economic structure on Tourism-Led Growth (TLG). A theoretical framework followed by an empirical analysis based on relevant data from 31 Chinese provinces for the years 1998–2013 is presented. The main conclusions of the econometric analysis are that tourism growth can help reduce the urban-rural gap in China, but that the larger the gap between urban and rural economies, the less substantial is the influence of tourism on economic growth in China. Tourism may play an important role in Central-Western and Inland China, but their relatively greater urban-rural economic gap may threaten the positive effect of tourism.  相似文献

The focus of this paper is the flexibility in working hours as a motive for entrepreneurship. The model exhibits inflexibilities for workers and entrepreneurs, which arise due to complementarities in production. In addition, it allows for volatile value of leisure to make flexibility in hours desirable. Differences in occupation-specific flexibility, disciplined with the observed patterns in hours (level, persistence, dispersion) and income (persistence, dispersion), can explain relatively low income levels of entrepreneurs in the US and the occupation-specific distributions of working hours and income. Policy relevance of the model features is discussed using experiments of workweek restrictions and income taxation.  相似文献

在经济全球化大环境下,企业具有更加多样化的会计信息,也就更需要能全面反映企业业绩的财务分析体系。多年来传统杜邦分析法虽因能系统、全面、直观地反映企业财务状况,提高对财务报表的分析效率,提升经营管理能力而得到企业的广泛应用,但它本身存在着诸多缺陷。针对其局限性,本文引入可持续增长率来改进传统的杜邦分析体系以更加符合现代企业的要求。  相似文献

What is the most appropriate combination of fiscal and monetary policies in economies subject to banking crises and deep recessions? We study this issue using an agent-based model that is able to reproduce a wide array of macro- and micro-empirical regularities. Simulation results suggest that policy mixes associating unconstrained, counter-cyclical fiscal policy and monetary policy targeting employment is required to stabilise the economy. We also show that “discipline-guided” fiscal rules can be self-defeating, as they depress the economy without improving public finances. Finally, we find that the effects of monetary and fiscal policies become sharper as the level of income inequality increases.  相似文献

Demographic structure could affect economic growth through many channels. However, little is known about how demographic structure affects economic growth since no study has examined an extensive collection of channels through which demographic structure could affect economic growth in a single context. This paper overcomes this limitation by examining 45 potential mediating variables between demographic structure and economic growth. A causal search algorithm is used to identify channels through which demographic structure affects economic growth. Our results suggest that demographic structure affects economic growth differently between developed and developing countries. For developed countries, we find that an increase in the share of middle-aged workers has a positive effect on economic growth through institutions, investment and education channels. On the other hand, an increase in the share of the senior population has a negative effect on economic growth through institutions and investment channels. For developing countries, we find (but with weak evidence) that an increase in the share of young workers has a negative effect on economic growth through investment, financial market development and trade channels.  相似文献

Among a number of households worldwide, forest use and income diversification have been seen as substitute livelihood strategies: farmers with more diverse income sources face a higher opportunity cost in harvesting forests and so tend to rely less on forestry resources. The current study uses rural household survey data captured in the Chinese provinces of Fujian, Shaanxi, Hunan, and Jiangxi. It applies a Heckman regression model and a quantile regression model to determine the effect of income diversification on forest dependence. The three main findings of this study are as follows. (1) The mean income diversification index values in Fujian, Shaanxi, Hunan, and Jiangxi are 1.81, 1.46, 1.63, and 2.00, respectively; this indicates that livelihood activities within the study areas are limited. (2) When the income diversification index increases by 10%, the proportion of forest income to total income within the study areas decreases by 4–8%; this indicates that income diversification can significantly reduce a household's dependence on forest resources, especially among the poorest households. (3) For the top 20% of high-income households, the effect of income diversification on forest dependence is insignificant, but for the bottom 20% of low-income households, income diversification has a major impact in terms of reducing their forest reliance (6–10%). The findings of this study will help inform the design of alternative policies that could alleviate pressure relating to forest-resource protection.  相似文献

We study the relationship between income inequality and economic freedom for a panel of 100 countries for the 1971–2010 period. Using a panel Granger non-causality approach, we reject the null hypothesis of Granger non-causality running from income inequality to economic freedom, but not vice versa. From a series of dynamic panel estimations we show that the effect of income inequality on economic freedom is negative and robust to the inclusion of additional controls. In particular, inequality is negatively associated with those components of economic freedom related to international trade, domestic market regulation as well as the rule of law and property rights protection. We argue that the negative effect of inequality on economic freedom is due to the economic elite converting its economic power into de facto political power to defend its economic interests; these interests run counter to economic freedom, discouraging innovation and competition as well as protecting the elite's rents. Finally, we show that economic freedom decreases with income inequality even in democratic countries, suggesting that democratic institutions do not prevent economic freedom from eroding. We argue that the latter finding corresponds to a system of political capitalism or captured democracy, where a powerful economic elite can nevertheless exercise de facto political power by cooperating with politicians and other decision-makers for their mutual benefit.  相似文献

Calculating the welfare implications of changes to economic policy or shocks requires economists to decide on a normative criterion. One approach is to elicit the relevant moral criteria from real-world policy choices, converting a normative decision into a positive inference, as in the recent surge of “inverse-optimum” research. We find that capitalizing on the potential of this approach is not as straightforward as we might hope. We perform the inverse-optimum inference on U.S. tax policy from 1979 through 2010 and argue that the results either undermine the normative relevance of the approach or challenge conventional assumptions upon which economists routinely rely when performing welfare evaluations.  相似文献
