流动性与资产定价:基于我国股市资产换手率与预期收益的实证研究

流动性与资产定价是目前金融研究的热点之一 (O’Hara,2 0 0 3 )。本文通过检验交易频率零假设和交易成本备择假设 ,深入分析我国股市流动性与资产定价的理论与经验关系 ,发现 :我国股市存在显著的流动性溢价 ,换手率低、交易成本高且流动性小的资产具有较高的预期收益 ;产生流动性溢价的原因是交易成本而不是交易频率 ;与国外股市相似 ,小企业收益率高于大企业 ,价值股收益率高于成长股。因此 ,我国股市并非令人无法捉摸 ,流动性、规模和价值效应都是资产定价的因素     

The ‘Puzzles’ methodology: En route to Indirect Inference?

We review the methods used in many papers to evaluate DSGE models by comparing their simulated moments with data moments. We compare these with the method of Indirect Inference to which they are closely related. We illustrate the comparison with contrasting assessments of a two-country model in two recent papers. We conclude that Indirect Inference is the proper end point of the puzzles methodology.

ALTERNATIVE OPTIMAL TRADE POLICIES IN THE PRESENCE OF FOREIGN INPUT MONOPOLY

Abstract.  This paper develops a generalized three-country model with downstream and upstream industries to analyze optimal import and export trade policies in the presence of monopoly distortion in a foreign intermediate input market. It shows that the import tariff and export tax are linearly dependent. Thus, the optimal choice of the tariff gives rise to the same results as the optimal choice of the export tax, which implies that the domestic government, to avoid tariff retaliation, can use export tax as a substitute for the import tariff.     

Monopsony and the production-location decision of the firm

This paper incorporates monopsony power in one of the input markets within the context of the Weber-Moses triangular framework and examines the effect of an increase in monopsony power on the production-location decision of the firm. In particular, this paper shows that the optimum location of the firm is independent of monopsony power if the production funstion is homogeneous of degree one. However, if the production function is not homogeneous of degree one, the firm possessing monopsony power will have an incentive to move its location away from the monopsonized input market towards other markets under certain reasonable assumptions. Finally, some important policy implications are generated from the analysis.     

Production location and random input price

The purpose of this paper is to develop systematically the theory of plant location for a competitive firm facing random input price. It will be shown that the impact of input price uncertainty on the firm's optimum location depend crucially upon (i) the firm's attitude toward risk, (ii) the characteristics of the production function, (iii) the structure of transport costs on inputs and output, and (iv) the type of input usages. Moreover, and more importantly, some conclusions obtained by prior studies on location theory in a certainty world can also be shown to be special cases of our more general results, but some are not justifiable in a world with random input price.     

Managerial Self-Interest, Pension Financial Slack and Corporate Pension Funding

This paper examines the impact of managerial self-interest on corporate pension funding decisions. It is postulated that managers with no ownership stake in the firm will have incentives to maintain financial slack in the form of excess pension funding. Pension funding slack may be viewed as a managerial perquisite that decreases the probability of necessary future debt financing. Such a strategy may increase the value of undiversified human capital to the detriment of maximizing shareholder wealth. As managerial ownership increases, the incentives to consume such a perquisite will decrease since the interests of managers and shareholders become more aligned. The results presented in this study strongly support this proposition.
