Sample attrition and labor force dynamics: Evidence from the Spanish labor force survey

In this paper we examine a number of issues that arise in investigating labor force dynamics using the Spanish Labor Force Survey (EPA). These issues are by no means specific to the Spanish case and apply to most European-style labor force surveys. Our main conclusions may be summarized as follows. First, survey nonresponse cannot be neglected. Second, the EPA tends to underestimate employment and participation of high-educated young people, and to overestimate those of the low-educated elderly. Finally, we find little evidence that attrition causes important selection biases in estimating quarterly transition probabilities.

Problems and environment of small businesses in the Czech Republic

The impressive and spontaneous build-up of the private small and medium-sized enterprises (SMEs) in the Czech Republic in 1990–93 coincided with the similarly dramatic changes in the public administration and in the whole environment for decision-making. The resulting problems of SMEs in the Czech Republic seem to be common to all economies in transition. A lot of the problems are caused by the macroeconomic policy for which this sector is not the most important part of the national economy. The paper shows some conflicts between macroeconomic anti-inflationary (monetary and fiscal) policies, and interests of small businesses. The authors stress the importance of SMEs during the period of transition. Informal aspects of the functioning of small firms are discussed, especially their relation with banks and public administration. The paper offers some empirical evidence and available statistics on SMEs developments during 1990–94 focusing particularly on manufacturing.     

Congestion effects in a public-good economy

This paper considers a public-good economy with congestion, where participants jointly produce a public good from input of a private good. This economic model gives rise to a transferable-utility game, the profit game, that depends on consumer preferences and a congestion parameter. The simplicity of the game allows the maximum level of congestion that guarantees the nonemptiness of the core of the economy to be determined. It is known that the sustainability of the Lindahl equilibrium in the core of the economy depends on the distribution of profits. In this paper two distributions of profits are compared: the Lindahl solution and the marginal-contribution solution. The latter is more often in the core than the Lindahl solution which in turn Lorenz-dominates the marginal-contribution solution.

中国邮政储蓄制度变迁：历史与趋势

邮政储蓄自恢复以来得到了迅速发展，但其负外部性逐渐凸现，从而影响到了中国经济发展的整体结构和金融体系的正常秩序。邮政储蓄制度改革已成为中国金融体系改革所关注的焦点之一，问题的产生在于背后的制度因素，制度变迁应该是改革邮政储蓄机构的根本路径。就邮政储蓄制度的现实而言，机构银行化是一个取向，但也并非一蹴而就，而表现为一个过程。改革推动者应该遵循整体利益大于制度成本的原则设计制度安排．

Automatic balancing mechanisms for notional defined contribution accounts in the presence of uncertainty

The notional defined contribution model combines pay-as-you-go financing and a defined contribution pension formula. This paper aims to demonstrate the extent to which liquidity and solvency indicators are affected by fluctuations in economic and demographic conditions and to explore the introduction of an automatic balancing mechanism (ABM) into the pension scheme. We demonstrate that the introduction of an ABM reduces the volatility of the buffer fund and that, in most cases, the automatic mechanism that re-establishes solvency produces the highest value of the risk-adjusted notional factor.
