The State, Institutional Transition and the Creation of New Urban Poverty in China

Since the 1990s, the introduction of a market economy and the process of rapid urbanization have been accompanied by a new urban poverty related to lay‐offs and unemployment as well as by large‐scale rural–urban migration, which is different from the traditional urban poverty of the ‘Three Nos’ (no relatives or dependants, no working capacity and no source of income). This article focuses on new urban poverty in China under market transition and discusses the causes of poverty creation. Instead of considering Chinese new urban poverty only as a result of market mechanisms, it argues that the state as the manipulator of institutions and policies does matter in the creation of new urban poverty, and that the cleavages between the old and new institutions further intensify it. Specifically, the following aspects of the creation of new urban poverty are examined in detail: the adjustment of industrial policy, the reform of state‐owned enterprises, evolution of the household registration system, and the transformation of the welfare state.

The relationship between paid work and parenthood--a comparison of structures,concepts and developments in the UK and Austria

This article investigates and compares the dominant concepts of public policy concerning the employment-parenthood interface in the UK and Austria. These two countries have been chosen because they represent very different public policy conceptions, particularly in approaching the work-family issue. In order to show the consequences of these policies the paper focuses on working time and time away from employment, when children are very young, and relates these aspects to currently introduced and changed regulatory structures, such as working time regulations and statutory parental leave. The active labour market and family policy in Austria, generally, supports the reconciliation of employment and parenthood. However, the Austrian work-family 'system' suffers from the underlying notion of the male breadwinner model in public support structures and low normative support of employed mothers. The cultural barriers for a more equal distribution of the burdens of combining employment and parenthood seem to be lower in the UK. The market as the political focus, in general, allows more equal opportunities for (qualified) women in the labour market and within families. But the highly flexible and polarised labour market, passive public policy and weak legal protection of employed parents creates a difficult relationship between paid work and family life for many parents, in particular for low-skilled, low-paid parents, above all mothers. These analyses provide the basis for conclusions for public policy aiming at the reconciliation of paid work and parenthood. Ce texte cherche à comparer les concepts dominants de la politique gouvernementale concernant l'interface travail-parent en Grande-Bretagne et en Autriche. Ces deux pays ont été choisis parce qu'ils présentent des concepts de politique gouvernementale très différents, en particulier en ce qui concerne la question de la famille et le travail. Ce texte montre les conséquences de la pratique de ces politiques sur le temps au travail rémunéréet le temps passé à l'extérieur de l'emploi ou sans emploi, et ce, dans un contexte o[ugrave] les enfants sont jeunes. Le texte fait la relation entre ces éléments et la pratique des structures de contrôle existantes et modifiées telles que les lois (ou: les règlements) sur le temps passéau travail et sur les congé parentaux. En général, le marché du travail et la politique de la famille en Autriche encourage la conciliation entre l'emploi et la responsabilité de parent. Par contre, ce système de travail- famille autrichien est un concept qui est fondé à la fois sur le modèle de l'homme comme fournisseur principal du revenu familial dans les structures de soutien public ainsi que sur normes de soutien peu élevées pour les mères employées. Les barrières culturelles face àune distribution plus égalitaire de la responsabilité travail-famille semblent être moins élevées en Grande-Bretagne. En général, le marché et la politique du marché du travail ont offerts plus d'opportunités aux femmes qualifiées. Mais la volatilité (et la polarisation) du marché du travail, la politique gouvernementale passive et la faible protection légale pour les parentstravailleurs créent tous une relation difficile pour les parents entre le travail rémunéré et la vie de famille--en particulier pour ceux qui sont moins qualifiés et mal rémunérés, dont surtout les mères de famille. Cette analyse nous guide vers la nécessité d'une politique gouvernementale qui vise la conciliation entre le travail rémunéré et la responsabilité parentale.

Sampling Returns for Realized Variance Calculations: Tick Time or Transaction Time?

This article introduces a new model for transaction prices in the presence of market microstructure noise in order to study the properties of the price process on two different time scales, namely, transaction time where prices are sampled with every transaction and tick time where prices are sampled with every price change. Both sampling schemes have been used in the literature on realized variance, but a formal investigation into their properties has been lacking. Our empirical and theoretical results indicate that the return dynamics in transaction time are very different from those in tick time and the choice of sampling scheme can therefore have an important impact on the properties of realized variance. For RV we find that tick time sampling is superior to transaction time sampling in terms of mean-squared-error, especially when the level of noise, number of ticks, or the arrival frequency of efficient price moves is low. Importantly, we show that while the microstructure noise may appear close to IID in transaction time, in tick time it is highly dependent. As a result, bias correction procedures that rely on the noise being independent, can fail in tick time and are better implemented in transaction time.     

经济法与市场经济——对现代经济法的一种认识

经济法是现代市场经济发展到一定阶段出现政府干预失灵的特定历史下产生的法律部门和法律学科.它不仅是政府干预经济的有效手段,也是政府干预的约束和规范,是政府干预法治化和市场秩序优化的必然需求.同时,现代经济法法益保护也具有双重性既侧重于社会公共利益的保护,又兼顾市场经济个体私利的保护,实现社会公益和个体私益的最大协调和平衡.     

Expected sample moments of concomitants of selected order statistics

In this paper, the task of determining expected values of sample moments, where the sample members have been selected based on noisy information, is considered. This task is a recurring problem in the theory of evolution strategies. Exact expressions for expected values of sums of products of concomitants of selected order statistics are derived. Then, using Edgeworth and Cornish-Fisher approximations, explicit results that depend on coefficients that can be determined numerically are obtained. While the results are exact only for normal populations, it is shown experimentally that including skewness and kurtosis in the calculations can yield greatly improved results for other distributions.

How can David orchestrate resources to enhance firm performance? A dynamic approach to coping with resource constraints

Given that the possession of abundant resources does not always guarantee superior firm performance, this study proposes a dynamic approach to enhancing firm value. Building on the resource orchestration thesis, we investigate how firms facing resource constraints enhance their capabilities over time by orchestrating resources and how this resource orchestration can play a role in improving firm performance. Using the dynamic perspective, this study identifies four resource orchestration modes, which are specified based on how a given firm dynamically allocates its resources to technology (enacted by R&D activities) and marketing (enacted by advertising activities). Accordingly, we claim that firms with resource constraints can enhance their performance by escalating or altering their resources over time. To test our hypotheses, we used a sample of 4078 small and medium-sized enterprises in manufacturing industries between 1984 and 2018. We found that focus escalation for technology positively affects firm performance, captured by Tobin's q, and that focus alternation toward either technology or market is positively related to firm performance. Finally, we discuss the theoretical and practical implications of our findings.
