Small start‐up firms are the engine of job creation in early transition. We ask about differences in their growth across two different transition economies: Estonia, which experienced rapid destruction of pre‐existing firms, and the Czech Republic, which reduced the old sector gradually. We find that the majority of job growth corresponds to within‐industry reallocation. The within‐industry growth of small start‐up firms is similar in the two countries, in line with the convergence to Western industry firm‐size distributions. We also find similar patterns in the evolution of wage differentials between start‐ups and old firms and small differences in the extent of low‐wage employment in start‐ups across the two transition paths.

The 1992–93 recession in the western states of Germany has been attributed, in substantial measure, to the macroeconomic consequences of policies to finance unification. Studies of the costs of unification have not attempted to measure the burden of the recession. We estimate a dynamic, panel model of household incomes using data from the German Socio-Economic Panel (GSOEP) and use it to forecast what these incomes would have been in 1992–94 without a recession. Using a ratio of actual to forecast incomes, we compare the relative burden of the recession across households. Our findings suggest that western households below the median income bore the brunt of the combined impact of unification and the recession of 1992–93.

Motivated by the implied stochastic volatility literature (Britten–Jones and Neuberger, forthcoming; Derman and Kani, 1997; Ledoit and Santa–Clara, 1998) this paper proposes a new and general method for constructing smile–consistent stochastic volatility models. The method is developed by recognising that option pricing and hedging can be accomplished via the simulation of the implied risk neutral distribution. We devise an algorithm for the simulation of the implied distribution, when the first two moments change over time. The algorithm can be implemented easily, and it is based on an economic interpretation of the concept of mixture of distributions. It can also be generalised to cases where more complicated forms for the mixture are assumed.  相似文献

市场经济的主要矛盾是生产与消费的矛盾,它决定商品与货币、供给与需求、总供给与总需求的矛盾。社会主义市场经济的主要矛盾是社会主义制度与市场经济体制的矛盾。当前存在的主要问题是生产相对过剩、消费需求不足,分配不够公平、贫富差距过大,市场秩序混乱、腐败现象严重,资源消耗过度、环境状况恶化,等等。只有正确处理社会主义市场经济的矛盾和问题,处理好公有制和私有制、计划与市场、效率与公平、自力更生与对外开放等各方面的关系,才能促进国民经济又好又快地发展。  相似文献

特许经营是一种新型的销售方式,作为企业分销系统的构成要素,能够起到降低风险,沟通生产与消费的作用。然而在实际经营过程中也会出现许多诸如指定购买与搭售、联合定价、独占经营等违反竞争法的问题。为适应不断变化的竞争形势,应从竞争法的层面上对其加以规制。  相似文献

改革开放以来,江苏居民收入普遍提高,人民生活得到很大改善,但近年来居民收入开始出现差距并且日益扩大,已成为影响社会稳定和经济发展的重要问题。文章首先分析了江苏居民收入分配的现状,然后剖析了影响居民收入分配差距过大的成因,在此基础上提出了防止居民收入差距过大的治理对策。  相似文献

一般理论认为,按生产要素分配主要体现在非公有制领域和公有制领域内劳动者收入来源的多样性上.但事实上,随着我国劳动力市场的发展和完善,按生产要素分配在公有制领域内将有更大的作用空间.其具体实现形式之一,即为公有制范围内劳动收入由V+Vm构成,而且对企业利润(M)中分配后的剩余部分,仍可实行按生产要素分配,而后者是建立国有资产保值增值机制的一种新思路.  相似文献

Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example.  相似文献

1. Introduction The village election was first envisioned by the late chairman of the National People’sCongress (NPC), Mr Peng Zhen, in the mid-1980s to enhance village governance after the commune system was dissolved in China in the early 1980s. In 1987, the NPC passed a tentative version of The Organic Law of the Village Committee (OLVC), and started a 10 year experiment of village elections. In 1998, the NPC formally passed the law and elections quickly spread to the whole count…  相似文献

I model imperfect information, derive a downward sloping market demand curve, and explain vacancies in a partial equilibrium model of a rental housing market. Tenants can be completely described by an exogenous demand curve, perhaps arising from differences in income, preferred location, or tastes, and view vacant units based on a stochastic arrival of rental information. Free entry of these landlords induces excess rental housing capacity (equilibrium vacancies). I determine the equilibrium distribution of rents for vacant units, show that this rent distribution may be discontinuous, and explore the equilibrium vacancy rate to changes in exogenous parameters. The resulting characterization of equilibrium distributions of rents may be amenable to econometric modeling exploring the relationship between market rents and vacancies.  相似文献
