地方行政编制总量影响因素实证研究——以安徽省县级政府为例

2009年安徽省56个县级政府数据显示,人口、财政和面积三大因素与行政编制总量之间均存在线性正相关关系,县级政府行政编制总量随着人口、财政支出和地域面积的扩大而增加,面积对行政编制总量影响最大、财政次之、人口影响最小。仅就某县级政府来说,地域面积一般情况下是不变的,户籍人口的变化幅度也很小,影响政府行政编制总量的主要因素是该地财政支出发生变化。在核定各县级地方政府编制总量的过程中要充分考虑各方面因素,特别是应充分考虑各地的人口流动情况,根据各地的常住人口而不是户籍人口来核定行政编制数量。     

MEASURING LIMITS OF ARBITRAGE IN FIXED‐INCOME MARKETS

An emerging literature relies on an index of limits of arbitrage in fixed‐income markets. We analyze the benefits of an index that is model‐free, robust, and intuitive. This new index strengthens the evidence that limits of arbitrage proxy for risks priced in the cross‐section of returns. Trading simulations show that the new index improves identification of limits of arbitrage because it bypasses a noisy estimation step. Relative value indices in the United States, United Kingdom, Japan, Germany, Italy, France, Switzerland, and Canada exhibit strong commonality and high correlations with local volatility and funding conditions. The indices are updated regularly and available publicly.

A Study of the Attitude toward Convergent Products: A Focus on the Consumer Perception of Functionalities

The convergent product is an increasingly important phenomenon in the marketplace. The convergent product allows the developer to include more and more diverse functionalities into their products, which can satisfy a broad range of consumer needs. However, failures of convergent products arouse the need to understand its functionalities, and the optimal combination of functionalities and their relationships to attitude and purchase intention. In addition, because convergent product has the potential to offer more diverse functionality, we consider if this will have impacts on instrumental and emotional needs fulfillment and attitude and purchase intention. Additionally, consumer innovativeness was examined to ascertain if there were differences among consumers on their classification of the functionalities, or if it will moderate functional diversity, needs fulfillment, and product attitude. Using the Kano model, this study examined the nature of these relationships by examining the functionalities of a smartphone. Overall, our results show that the convergent products that include functionalities from two of the three categories of the Kano model, must‐have and attractive, were rated more positively. Consumer innovativeness differences were found. Consumers with high innovativeness considered must‐have and one‐dimensional functionalities the most important, and consumers with low innovativeness considered all three important, although one‐dimensional functionalities were considered significantly less important. Although increasing functional diversity positively raises product attitude and purchase intention, it tends to raise emotional needs fulfillment only once instrumental needs have been met, especially for respondents showing low innovativeness. The findings should arouse interest about factors that should not be overlooked when developing new convergent products.

DIFFERENTIAL RISK‐TAKING IMPLICATIONS OF PERFORMANCE INCENTIVES FROM STOCK AND STOCK OPTION HOLDINGS

We study the risk‐taking implications of managerial pay‐for‐performance incentives (delta) arising from stock and stock options separately in the United States between 1992 and 2017. The current literature assumes that each unit of delta has an equal incentive effect on firm performance. Instead, we show that the risk‐reducing effect of performance incentives is more pronounced for executives whose delta comes mostly from stock holdings relative to option holdings. Accordingly, we propose a new measure that takes into account the magnitude of delta from option holdings relative to delta from stock holdings (source ratio). Our results show that risk taking increases as this ratio increases.
