关于绩效审计研究的新思考

自20世纪60年代以来，不少学者对绩效审计展开研究，并取得了一些积极的成果，但总体研究状况并不乐观。本文分析了其中的原因，并就解决该问题提出了若干新的建议。     

Interest rate rules and macroeconomic stability with transaction costs

This paper analyzes the relationship between interest-rate feedback rules and macroeconomic stability in the presence of transaction costs. We show that with the Sims-type (1994) transaction-cost technology, a passive, rather than an active, interest-rate rule is more likely to generate a stabilizing effect against belief-driven fluctuations if both the intertemporal elasticity of substitution with respect to consumption and the sensitivity of the transaction costs with respect to the velocity of money are low. This result is valid under either an unbounded or a bounded transaction-cost technology. Of importance, our result is relevant under empirically plausible parameters, while it sharply contrasts with Taylor's (1993) prediction.     

论跨国公司对华投资与我国低碳经济的发展

跨国公司对华投资促进了我国经济的增长,但同时所带来的环境污染等一系列问题对我国低碳经济的发展构成了挑战.1999-2009年间,随着跨国公司对华投资规模的不断加大,尤其是对第二产业的投资,使得我国环境污染严重,对发展低碳经济带来严重挑战.深入研究和妥善解决这些问题,对于促进新时期我国利用外资的进一步发展具有重要的意义.     

经济增长、税收收入与宏观税负——基于中国宏观经济数据的实证研究

本研究以经济增长、税收收入与宏观税负三者间的关系为研究对象,利用中国2006年第1季度至2011年第3季度的税收收入、GDP和所计算得出的小口径宏观税负的数据,以供给学派经济学家亚瑟.拉弗（Arthur Laffer）提出的著名的＂拉弗曲线＂（Laffer-curve）为指导,建立计量经济模型,分别测算实现经济增长最大化的宏观税负和实现政府税收收入最大化的宏观税负,并分析了中国税收收入与经济增长的关系,为近年来中国积极推进财税体制改革和近期出台的结构性减税政策提供支持。     

Comparative advantage and unemployment

Worker heterogeneity in productivity and labor supply is introduced into a matching model. Workers who earn high wages and work high-hours are identified as those with strong market comparative advantage—high rents from being employed. The model is calibrated to match separation, job finding, and employment in the SIPP data. The model predicts a big drop in employment for workers with weak comparative advantage during recessions. But the data show that workers with strong comparative advantage also display sizable employment fluctuations, implying that aggregate employment fluctuations are not explained by the responses of workers with small rents to employment.     

Short selling activity,price efficiency and fundamental value of IPO stocks

In this study, we take advantage of the unique features of the Taiwan stock market, where short selling is forbidden within the first six months following an IPO. We examine the effects of short selling on IPO price efficiency and the relation between short selling activities and the fundamental value of IPO stocks. We find that price efficiency is improved with increased short selling after the lifting of short sale constraints on IPO stocks. We also show that short sellers tend to target IPO stocks with low fundamental ratios, but simultaneously avoid stocks with high transaction costs. In addition, we provide empirical evidence that short sellers focus more on temporary price fluctuations rather than temporary fluctuations in fundamentals.     

Personalized goal-based investing via multi-stage stochastic goal programming

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services.     

Institutional Monitoring: Evidence from the F‐Score

The extant literature shows that institutional investors engage in corporate governance to enhance a firm's long‐term value. Measuring firm performance using the F‐Score, we examine the persistent monitoring role of institutional investors and identify the financial aspects of a firm that institutional monitoring improves. We find strong evidence that long‐term institutions with large shareholdings consistently improve a firm's F‐Score and that such activity occurs primarily through the enhancement of the firm's operating efficiency. Other institutions reduce a firm's F‐Score. Moreover, we find evidence that, while monitoring institutions improve a firm's financial health, transient (followed by non‐transient) institutions trade on this information.
