Optimal Returns Policy under Demand Uncertainty

Multiple categories of retail products suffer limited shelf life, demand uncertainty, and, in some cases, long lead times. To provide retailers with an incentive to increase the stocking quantity of such products, manufacturers may offer an option to return unsold items at wholesale or less than wholesale prices. This article extends the additive price-dependent demand model in three ways. First, partial returns are optimal for the manufacturer but do not induce higher stocking quantities compared with when the manufacturer offers no returns. Second, in terms of the effect of investment in demand-enhancing activities, when retailers invest, they set higher resale prices, but an optimal partial returns policy still does not induce higher stocking quantity, whereas when manufacturers invest, the optimal returns policy induces higher stocking quantity. Third, when the manufacturer and retailer have different expectations of demand uncertainty, the retailer's estimate influences the expected profits for both, whereas the manufacturer's estimate has a major impact on its profits only.     

Effort optimisation in artisanal fisheries with multiple management objectives,collective quotas and heterogeneous fleets*

In this study, we analyse effort optimisation in common rights‐based joint‐stock artisanal fisheries when several objectives are pursued by the authorities and the fleets are heterogeneous. The purpose is to discuss policy options available to the authorities and their implications in terms of trade‐offs between goals. We apply a multi‐objective programming model to the sardine and anchovy artisanal fisheries in central southern Chile. The results suggest that the regulatory system generates inefficient solutions for profit and employment maximisation goals. Moreover, the fleet structure of the artisanal organisations is central for the outcomes obtained by different policy simulations. To improve effort assignment, the authorities should seek to increase flexibility in the system.     

Are microfinance markets monopolistic?

Do microfinance institutions (MFIs) operate in a monopoly, monopolistic competition environment or are their revenues derived under perfect competition markets? We employ the Panzar–Rosse revenue test on a global panel data to assess the competitive environment in which MFIs of five selected countries operate: Ecuador, India, Indonesia, Peru and Philippines, over the period 2005–2009. We estimate the static and the dynamic revenue tests, with analyses of the interest rate and the return on assets. We control for microfinance-specific variables such as capital-assets-ratio, loans-assets and the size of the MFI. The analyses also account for the endogeneity problem by employing the fixed-effects two-stage least squares and the fixed-effects system generalized method of moments. Our results suggest that MFIs in Peru and India operate in a monopolistic environment. We also find weak evidence that the microfinance industry in Ecuador, Indonesia and Philippines may operate under perfect competition.     

我国税收优先权制度存在的缺陷及其完善

2001年修订后的《税收征收管理法》首次规定了税收优先权制度,明确了税收债权与其他债权的清偿顺序,对于保证国家税收的实现具有重要的意义,但该规定存在诸多缺陷,有待进一步完善。     

不同类型增值税的税收中性分析

我国采用生产型增值税,增值税的税收中性特征没有充分体现出来,对于宏观经济运行和微观主体的行为都有一定的干扰。从税收中性的角度分析,消费型增值税的超额税收负担最小,最符合增值税的中性特征,是我国增值税改革的方向。     

多渠道实现高校融资规模效益研究

1999年我国高校开始扩招以来，高校为了实现规模的扩大开始大量举债。极度扩张之后，高校贷款后遗症随后出现，经费有限，贷款期限短，无法短期还贷，光靠扩张规模已经不符合新时期高等教育发展的要求。要转变高校发展理念，重人才培养而不是重规模。实现适度融资规模效应，以往依靠商业银行贷款的方式则要转向政府、高校、社会三方的共同努力得以实现。     

The informativeness of domestic and foreign investors’ stock trades: Evidence from the perfectly segmented Chinese market

This paper uses the perfect market segmentation setting in China's stock market to compare the information content of the stock trades of domestic and foreign investors. We study 76 firms that issue both A-shares (for domestic investors) and B-shares (for foreign investors) and compare the price discovery role of the two segmented markets in China. Before Feb 19, 2001, the A-share market led the B-share market in price discovery, as the signed volume and quote revision of the A-share market had strong predictive ability for B-share quote returns, but not vice versa. After Feb 19, 2001, because some domestic investors were allowed to invest in the B-share market, we find evidence for a reverse causality from the B-share to the A-share market. Nevertheless, the [Hasbrouck (1995). One security, many markets: determining the contributions to price discovery, Journal of Finance 50, 1175–1199.] information share analysis reveals that A-shares continue to dominate the price discovery process.

国内税的关税替代效应分析

关税的作用机制在于造成了产品在国外和国内的价格差异,从而产生保护国内生产商的经济效果。如果能够区分国内和国外的生产商,实施不同的国内税政策,国内税的运用同样可以造成相应的保护效果,因此,国内税在某种程度上也可以看作是贸易政策。
