In this paper, we generalize recursive utility to include lifetime uncertainty and utility from bequest. The generalization applies to discrete-time as well as continuous-time recursive utility, and it is an important step forward in the development of recursive utility. We formalize the problem of optimal consumption, investment, and life insurance choice under recursive utility, and we state a verification theorem with a generalized Hamilton-Jacobi-Bellman equation. Our generalization of recursive utility allows us to study optimal consumption, investment, and life insurance choice under separation of (market) risk aversion, elasticity of inter-temporal substitution, and elasticity of substitution between bequest and future utility. The separation gives rise to hump-shaped consumption patterns as observed in realized consumption. 相似文献

A separation between the academic subjects statistics and mathematical statistics has existed in Sweden almost as long as there have been statistics professors. The same distinction has not been maintained in other countries. Why has it been kept for so long in Sweden, and what consequences may it have had? In May 2015, it was 100 years since Mathematical Statistics was formally established as an academic discipline at a Swedish university where Statistics had existed since the turn of the century. We give an account of the debate in Lund and elsewhere about this division during the first decades after 1900 and present two of its leading personalities. The Lund University astronomer (and mathematical statistician) C. V. L. Charlier was a leading proponent for a position in mathematical statistics at the university. Charlier's adversary in the debate was Pontus Fahlbeck, professor in political science and statistics, who reserved the word statistics for ‘statistics as a social science’. Charlier not only secured the first academic position in Sweden in mathematical statistics for his former PhD student Sven Wicksell but also demonstrated that a mathematical statistician can be influential in matters of state, finance as well as in different natural sciences. Fahlbeck saw mathematical statistics as a set of tools that sometimes could be useful in his brand of statistics. After a summary of the organisational, educational and scientific growth of the statistical sciences in Sweden that has taken place during the last 50 years, we discuss what effects the Charlier–Fahlbeck divergence might have had on this development. 相似文献

A control block trade can be explained by the expectation of financial gains, shared by all shareholders, or by the expectation of private benefits, exclusive to the buyer and possibly at the expense of other shareholders’ rents. The market for corporate control contributes to social welfare when it improves the efficiency of the allocation of resources. When the objective of a block transaction is private benefits, social welfare may be negatively impacted as minority shareholders could withdraw from the market. Therefore the estimation of private benefits would allow the efficiency of the market for corporate control to be assessed. Specifically, the aim of this paper is to calculate private benefits in the Spanish market for partial control. Using a sample of partial control transactions over the period 1990–2016, we find that the median of private benefits is negative, therefore it appears that there is no inefficient use of resources in the Spanish partial control market as a whole, however private costs are detected. The variability of private benefits is explained in a significant way by variables related to the control structure of the target firm, such as the controlling position of the buyer after the transaction, the contestability of control and the cross-shareholdings between the buyer and large shareholders. Performance and the size of the firm are significant as well. 相似文献

This paper constructs three-sector general equilibrium models to investigate how public pollution abatement affects the skilled–unskilled wage inequality. In the basic model with full employment, we find that a higher degree of public pollution abatement will decrease the wage inequality if the intensity of skilled labor in the urban skilled sector is sufficiently large and expand or narrow down the wage gap if this intensity is sufficiently small. In the extended models, we consider other four cases, and obtain the results similar or dissimilar to that of the basic model. 相似文献

We examine the impact of air pollution on a firm's capital-labor ratio. We propose the hypothesis that, in dealing with air pollution, a firm responds strategically by using relatively more capital and less labor to contain labor costs and remain competitive in the market. Using a sample of Chinese firms and a satellite-based air pollution metric, we test this hypothesis, and our results confirm it. In addition, we document that the impact of air pollution on the capital-labor ratio is more salient for firms with high economic incentives and close monitoring. Further, we report that to respond to worsening air pollution, a firm uses more capital and substitutes lower-quality labor with more high-quality labor. Finally, after increasing the capital-labor ratio, a firm's value increases, in terms of Tobin's Q, suggesting that the adoption of a higher capital-labor ratio, due to air pollution, is a sound business strategy. 相似文献

This study examines the use of Management Control Systems (MCS) in travel and tourism start-ups. The study empirically examines 176 European tourism start-ups; data are collected via an online survey of start-up CEOs, and supplemented by financial statements of early-stage tourism firms. The results show that travel and tourism start-ups use formal systems for management control. We observe a relationship between the usage of these systems with specific internal and external environment characteristics. Finally, the results show that the historical financial performance of travel and tourism start-up firms affects MCS usage. 相似文献

Based on the day-night PM2.5 difference of the nearest atmospheric monitoring points to measure whether there is illegal emission, this paper explores the impact of environmental protection officials' tenure (EPLT) on illegal emissions. The results show that there is a positive correlation between EPLT and illegal emissions. Stable EPLT can reduce illegal emissions by increasing environmental information disclosure and environmental subsidies. It can increase illegal emissions by weakening public pollution reporting and media supervision, environmental law enforcement and promoting corruption. In addition, EPLT can increase illegal emissions as EPLT is less than 3.55 years, while EPLT can increase illegal emissions as EPLT exceeds 6.21 years. Further, when mayor's tenure and EPLT are both stable, the promotion effect of EPLT on illegal emission is stronger. Stable company director's tenure can also aggravate the promotion effect of EPLT on illegal emissions. 相似文献

The paper concerns the study of equilibrium points, or steady states, of economic systems arising in modeling optimal investment with vintage capital, namely, systems where all key variables (capitals, investments, prices) are indexed not only by time but also by age. Capital accumulation is hence described as a partial differential equation (briefly, PDE), and equilibrium points are in fact equilibrium distributions in the variable of ages. A general method is developed to compute and study equilibrium points of a wide range of infinite dimensional, infinite horizon, optimal control problems. We apply the method to optimal investment with vintage capital, for a variety of data, deriving existence and uniqueness of equilibrium distribution, as well as analytic formulas for optimal controls and trajectories in the long run. The examples suggest that the same method can be applied to other economic problems displaying heterogeneity. This shows how effective the theoretical machinery of optimal control in infinite dimension is in computing explicitly equilibrium distributions. To this extent, the results of this work constitute a first crucial step towards a thorough understanding of the behavior of optimal paths in the long run. 相似文献

This study seeks to contribute to the existing business strategy and the environment literature by examining the effect of governance structures on Chinese firms' environmental performance, and consequently ascertain the extent to which the financial performance–environmental performance nexus is moderated by governance mechanisms. Using a sample of Chinese companies from heavily polluting industries over a 5-year period, our baseline findings suggest that, on average, board size and governing board meetings are positively associated with Chinese firms' environmental performance, whilst board independence and gender diversity have positive, but insignificant association with firms' environmental performance. Our evidence suggests further that the examined internal governance mechanisms have a mixed moderating effect on the link between financial performance and environmental performance. Our findings have important implications for company executives, environmental activists, policy-makers, and regulators. Our results support insights drawn from agency, resource dependence, stakeholder, and legitimacy theories. 相似文献
