中国上市公司资本结构动态调整机制研究

本文从动态角度对中国上市公司资本结构的调整行为进行了研究.结果表明,我国上市公司存在最优资本结构,整体上表现为负债不足,由于调整成本的存在使得公司在偏离最优水平后只能进行部分调整.调整速度会受到公司规模、成长性和偏离最优水平的程度等因素影响,而且会因时间、行业和公司规模的不同而存在显著差异.     

The effects of experience and task difficulty on accuracy and confidence assessments of auditors

This study extends prior research in psychology and auditing by examining the effects of audit experience and task difficulty on control risk evaluation. It also examines whether the effect of framing is mitigated by the simultaneous presentation of information. Ninety‐eight auditors performed a control risk evaluation task and recorded their judgement and their confidence. We find that judgement confidence increases with audit experience and that judgement confidence decreases as perceived task difficulty increases. However, we find no relation between audit experience and judgement accuracy or between perceived task difficulty and judgement accuracy. In addition, we find a significant negative relation between judgement confidence and judgement accuracy, which indicates that the participants' confidence is not appropriate. As expected, there is no framing effect when information is presented simultaneously.     

Estimating the commuting cost and commuting time property price gradients

In this paper, we estimate the property price gradients in Hong Kong. We distinguish our effort from previous studies on the subject by directly measuring the economic distance, i.e., the monetary commuting cost and commuting time, instead of merely the physical distance. Our results are generally supportive of the prediction of a negative property price gradient. In one specification, the estimated capitalization of the savings of commuting cost in property prices appears to be just right. The expected negative effect of commuting time on property values, however, can only be detected among observations with larger commuting times. Nevertheless, over the range where the effect of commuting time has the expected negative sign, the values of time implied by the estimates agree well with the results reported in the transportation economics literature.     

Public Enterprise Privatization: A General Equilibrium Analysis

This paper develops a general equilibrium model to examine the short‐run and long‐run optimal privatization policies. By assuming that all firms are public firms initially, the paper focuses on how the degree of product differentiation γ and the average efficiency of the industry influence the determination of the optimal privatization policy. The paper shows that privatization decreases the more efficient firms' outputs while increases the less efficient firms' outputs in the short run, and reduces all firms' outputs in the long run. The paper also shows that the larger is γ and the smaller is the number of firms, the more privatized will be the public firm in the short run. Moreover, as γ or the entry barrier f_E is sufficiently small, full privatization is the best policy in the long run. On the contrary, as γ and f_E are large enough, partial privatization is optimal.     

Relative scarcity and convenience yield: evidence from non-ferrous metals

We study the relationship between convenience yield and relative scarcity in the non-ferrous metal market for the period January 2000–March 2015. We identify various sets of economic relationships for six major base metals, namely, aluminium, copper, lead, nickel, tin and zinc. Our bivariate and multivariate VARs and associated Granger-causality test results generally support the existence of a positive relationship between convenience yields of base metals and our relative scarcity measure. Furthermore, the time-varying characteristics observed in the results, especially during contango and backwardation periods, provide useful information to market players in developing inventory strategies.     

Does the budget process matter for infrastructure spending? Capital budgeting in local government

Investment in long-term capital projects plays an increasingly important role in improving the quality of many public services, as well as promoting economic development. Using data on capital spending and capital budget structures in county governments in Georgia, USA, this paper explains how a separate capital budget protects infrastructure spending in times of fiscal distress. The author found little evidence that county governments with a separate capital budget spent more than those without a capital budget.     

Bounds and prices of currency cross-rate options

This paper derives the pricing bounds of a currency cross-rate option using the option prices of two related dollar rates via a copula theory and presents the analytical properties of the bounds under the Gaussian framework. Our option pricing bounds are useful, because (1) they are general in the sense that they do not rely on the distribution assumptions of the state variables or on the selection of the copula function; (2) they are portfolios of the dollar-rate options and hence are potential hedging instruments for cross-rate options; and (3) they can be applied to generate bounds on deltas. The empirical tests suggest that there are persistent and stable relationships between the market prices and the estimated bounds of the cross-rate options and that our option pricing bounds (obtained from the market prices of options on two dollar rates) and the historical correlation of two dollar rates are highly informative for explaining the prices of the cross-rate options. Moreover, the empirical results are consistent with the predictions of the analytical properties under the Gaussian framework and are robust in various aspects.     

Slow-food-seeking behaviour,authentic experience,and perceived slow value of a slow-life festival

This study examines the antecedents and consequences of perceived “slow” value in a structural model – specifically, the role authenticity plays for visitors who seek slow food and participate in slow-life-related programme activities. Data were collected from participants in a slow-life festival in South Korea. Results show that slow-food-seeking behaviour has a significant effect on the authentic experience, and both concepts affect the perception of “slow” value of the event. Attitude and the intention to revisit were significant consequences of “slow” value. This study extends the knowledge about tourist behaviour in slow-life-related activities, particularly in a non-Western context, and suggests that a slow-life-related event should consider visitors’ preference for slow food and a programme that stages authentic experiences.
