Economic freedom in the long run: evidence from OECD countries (1850–2007)

This article presents historical indices for the main dimensions of economic freedom and an aggregate index for the developed countries of today, specifically pre‐1994 OECD members. Economic liberty expanded over the last century‐and‐a‐half, reaching more than two‐thirds of its possible maximum. However, its evolution has been far from linear. After a substantial improvement from the mid‐nineteenth century, the First World War brought a major setback. The postwar recovery up to 1929 was followed by a dramatic decline in the 1930s. Significant progress took place during the 1950s but fell short of the pre‐First World War peak. After a period of stagnation, steady expansion since the early 1980s has resulted in the highest levels of economic liberty of the last two centuries. Each of the main dimensions of economic freedom exhibited a distinctive trend and its contribution to the aggregate index varied over time. Overall, improved property rights provided the main contribution to the long‐run advancement of economic liberty.     

政府公共服务的企业化改革

传统政府治理中的一个误区是忽视服务提供和服务主体之间的区别，进而错误地认为如果政府放弃了服务生产者的功能，它自然就放弃了服务提供者的角色。政府的自信甚至自负导致公共物品垄断性的直接生产模式，它所伴随的高成本，低效率，质量不尽人意和回应性的缺乏，不仅损坏了公众对政府的信任，而且无端耗费了公共资源，导致普遍的低效。     

The surprising benefits of a parallel universe

Suppose that the successful completion of a project requires performing n tasks, each of which has a probability of success p. The paper establishes under what conditions it may be profitable to engage in parallel multi‐tasking, i.e. tackling each task by following two independent routes. It is found that for ?n>1 parallel multi‐tasking is profitable for a wide range of parameters when costs are linear and is always profitable for convex costs.

HEATH–JARROW–MORTON INTEREST RATE DYNAMICS AND APPROXIMATELY CONSISTENT FORWARD RATE CURVES

We study a finite-dimensional approach to the Heath–Jarrow–Morton model for interest rate and introduce a notion of approximate consistency for a family of functions in a deterministic and stochastic framework. This amounts to asking the decrease of the minimum distance in least squares sense. We start from a general linearly parameterized set of functions and extend the theory to a nonlinear Nelson–Siegel family. Necessary and sufficient condition to have approximately consistency are given as well as a criterion of stability for the approximation.     

A NEW MULTIPLICATIVE DECOMPOSITION FOR THE FOSTER–GREER–THORBECKE POVERTY INDICES

This paper shows that Foster–Greer–Thorbecke poverty indices can be written as the product of components summarizing the incidence, intensity and inequality dimensions of poverty and provides an empirical illustration of the decomposition using Spanish household budget surveys data.

如何建立企业顾客抱怨管理体系

<正>一、分析顾客抱怨的原因及对企业的影响导致顾客抱怨的因素是多种多样,因事而异,因人而异,但总的来说可以归纳为以下两个方面: 1.产品问题导致顾客抱怨。由于产品问题引起的顾客抱怨以致投诉是一种常见的顾客不满的表达形式,如您购买的冰霜不到半年就发生不制冷现象,或刚买的衣服第一次穿就掉了钮扣等。产品问题的产生,可以归因于3方面的责任:一是生产者的责     

Takeover bids, unconditional offer price and investor protection

In this paper, we develop a contingent claim analysis on shareholders' right to sell unconditionally their shares at the acquisition bid price during a takeover bid procedure. Compared with a situation without any guarantee, this regulation brings about wealth transfer towards outside shareholders. Why, in an apparently irrational way, do outside shareholders, who may benefit from a price guarantee, not systematically sell their shares? That question emphasizes the outside shareholders' behavior. Using a real option valuation model to evaluate the price guarantee opportunity, we show that an equal treatment rule between controlling and outside shareholders may lead outside shareholders to sell their shares.
