Privatization of refuse removal and labor costs

We examine the labor-cost savings associated with privatization by comparing earnings and employment trends of public and private sector refuse workers. Findings suggest that high union earnings for workers in the public sector are a source of labor-cost savings in the refuse industry. Evidence on job changers does not indicate that earnings for this group of workers are a compensating differential. Metropolitan area employment findings suggest that municipalities are less likely to use union refuse workers in the public sector when a relatively small percentage of area residents belong to a union.

Deposit Insurance,Institutions, and Bank Interest Rates

Many recent institutional reforms of the financial system have relied on the introduction of an explicit scheme of deposit insurance. This instrument aims at two main targets, contributing to systemic stability and protecting depositors. However, it may also affect the interest rate spread in the banking system, which can be viewed as an indicator of either inefficiency or market power in this financial segment. This paper provides an empirical investigation of the effect of deposit insurance and other institutional and economic variables on bank interest rates across countries. We find that deposit insurance increases the lending–deposit spread in banking. The main effect seems to arise not from the deposit side though, but from an increase in the lending rate. We interpret this result as evidence of the presence of moral hazard problems related to this instrument. We also find that higher quality of institutions is associated with lower spreads, thus contributing to eroding sources of market power in the banking sector.

我国人口城乡分布的统计问题

人口的城乡分布是观察国民经济结构和社会发展水平的重要依据。进入80年代以来,我国人口的城市化趋势明显加快,为国内外人士所注目。1990年第四次人口普查后,国家统计局根据普查材料对我国1982年以后的城乡人口数字进行了大幅度的调整。这就更加引起了大家的兴趣,希望弄清楚80年代人口城乡分布统计究竟有些什么问题,经过调整之后哪些问题解决了,哪些问题还没有解决。本文拟就这些问题提出个人的一些看法。

论"革命文学"的流行性艺术素质

“革命文学”之所以在1920年代后期广为流行,其中一个重要原因,就在于它采用了为广大读者熟悉并喜爱的艺术手法,从而使其艺术素质隐含着一定的流行态势。“革命文学”的独特叙事方式,缩短了读者与作家及作品人物之间的距离,增加了叙事的真实性与感染力。而它在题材上呈现出的“故事类型”化特点,以及局部细节描写上的“套式”形态,都便于读者的理解与接受。此外,传统的人物描写手法以及语言的简单易懂,又进一步促进了“革命文学”的广泛流行。
