On hierarchical competition in oligopoly

In this paper, we consider a hierarchical oligopoly model, in which firms compete on quantities of an homogeneous product. We provide a proof and an interpretation that under the three necessary and sufficient conditions of linear aggregate demand, constant and identical marginal costs, the strategy of leaders at any stage depends neither on the number of leaders who play after nor on the number of remaining stages. So, all firms behave as Cournotian oligopolists on the residual demand. We show that these three assumptions are not only sufficient but also necessary. Any departure from any of these assumptions rules out this property.     

江苏省经济利益关系的调整与和谐社会的建设

该文首先提出了衡量利益关系是否和谐的四条标准,以此标准衡量江苏省发现,江苏的利益关系大体上是和谐的,但也存在不和谐的因素。其次,根据江苏省现状,提出了必须着力调整的四对经济利益关系,即城乡关系、公共服务的供求关系、劳资关系、干群关系。最后提出了构建江苏省和谐社会的途径:树立并引导主流价值观的形成;建立社会舆情分析机制,扩展利益诉求通道;壮大中产阶层,造就“橄榄”型社会阶层结构。

Analysis of fatal injuries in Serbian underground coal mines – 50 years review

Abstract

The study presented here analyzes mining accidents and fatal injuries in Serbian underground coal mines over a period of 50?years, in order to assess the effectiveness of legislation changes in the overall safety of work environment. Two distinct periods, prior to 2000 and after 2000 were compared. The data from the period after 2000 were further analyzed to provide better understanding of the results. In order to assess the overall state of safety in Serbian mines, the data on fatal injuries were also compared to the international data. It was found that the legislative changes are more easily accepted by the common workers than by the mine management. Consequently, the key recommendation for the safety of coal mine companies in Serbia is the investment in the new technology. Additionally, mine management should be in the focus of the mining inspection with a stronger penal policy regarding mine safety neglect.     

Mixture periodic GARCH models: theory and applications

This paper discusses mixture periodic GARCH (M-PGARCH) models that constitute very flexible class of nonlinear time series models of the conditional variance. It turns out that they are more parsimonious comparatively to MPARCH models. We first provide some probabilistic properties of this class of models. We thus propose an estimation method based on the expectation-maximization algorithm. Finally, we apply this methodology to model the spot rates of the Algerian dinar against euro and US dollar. This empirical analysis shows that M-PGARCH models yield the best performance among the competing models.

Dynamic Olley‐Pakes productivity decomposition with entry and exit

We propose an extension of the Olley and Pakes ( 1996 ) productivity decomposition that accounts for the contributions of surviving, entering, and exiting firms to aggregate productivity changes. We argue that the other decompositions that break down aggregate productivity changes into similar components introduce some biases in the measurement of the contributions of entry and exit. We apply our proposed decomposition to Slovenian manufacturing data and contrast our results with those of other decompositions. We find that, over a five‐year period, the measurement bias associated with entry and exit is substantial, accounting for up to 10 percentage points of aggregate productivity growth.     

Pay me Right: Reference Values and Executive Compensation

This paper examines the importance of reference values for executive compensation contracts. We rely on a quasi‐experimental setting (the adoption of pay guidelines), and a well‐defined measure of individual‐specific reference values to provide evidence on how a change in CEO reference compensation leads to subsequent changes of actual pay. We find that executive compensation adjusts gradually towards the new reference values, and that the speed of the adjustment depends on the corporate governance characteristics: the firm ownership structure, the role of the State and of the employees in the firm decision making. These results provide empirical support for theoretical models of bargaining that take into account reference values.
