劳动力市场的新趋势与养老保险制度的完善

自20世纪90年代末以来,随着经济体制改革的推进和社会的发展变迁,我国劳动力市场出现劳动参与率下降、灵活就业形式越来越普遍的现象,并且人口老龄化日益显现,未来劳动力供给可能减少,劳动力市场的这些新趋势将给养老保险制度带来挑战,本文拟对此进行分析,并在此基础上对养老保险制度的完善提出对策建议。     

我国股票市场运行中的政府行为研究

金融证券理论认为投资者行为受市场机制约束,政府的作用在于防止投资者脱离投资理性。但我国股票市场是在政府主导下运行的,政府行为不仅导致市场的波动,而且还可以改变市场运行的方向。政府主导市场的结果是扭曲了投资者行为,加大了市场"泡沫",并为利益集团寻租创造了条件。

The Lack of International Consumption Risk Sharing: Can Inflation Differentials and Trading Costs Help Explain the Puzzle?

The bulk of evidence on the lack of international risk sharing is based on regressions of idiosyncratic consumption growth on idiosyncratic output growth. This paper argues that the results from such regressions obtained from international data are, however, not directly comparable to those based on regional data: the standard practice of running such regressions on international data fails to account for persistent international differentials in consumer prices, whereas—implicitly—most of the literature based on regional data has accounted for these differences. When risk sharing regressions are set up in conceptually the same way in international and regional data sets, the estimated coefficients are also very similar. To explore this result further, we adapt the variance decomposition of Asdrubali et al. (Q J Econ 111:1081–1110, 1996) to allow for deviations from purchasing power parity across countries. While quantity (income and credit) flows are the dominant channel of risk sharing among regions, relative consumption and output price (internal terms of trade) fluctuations account for the bulk of the deviation from the complete markets outcome in international data. To the extent that persistent differences in consumer prices are an indication of goods market segmentation, our findings provide empirical evidence for the proposition by Obstfeld and Rogoff (NBER Macroeconomics Annual 2000, 2000) that segmented international goods markets rather than asset market incompleteness may account for the (apparent) lack of risk sharing between countries.

我国央行公开市场操作策略与流动性效应

本文检验了不同操作策略下中国央行公开市场操作流动性效应。通过构建并计算央行公开市场操作指标值,根据取值区间将公开市场操作定义为五种操作策略。本文采用2006年10月至2012年3月的数据,估算了每月超额准备金,并计算出实际的公开市场操作指标值,利用排序自回归法证实了央行公开市场操作对利率有非线性影响,进一步建立非线性多阈值自回归模型,研究了不同操作策略的公开市场操作对3个月短期市场利率的影响。实证结果表明央行公开市场操作可分为四种策略,主要表现为防御性功能,但不存在周流动性效应。     

Brazilian Micro-enterprises＇ An Exploratory Study on Marketing Strategies

This article aims to present the main marketing concepts applied by Brazilian micro-enterprises within a brief contextualization of a marketing plan. The methodology involved qualitative research development applied at the Trianon Fair, traditional event on Sundays on the sidewalks of the AvenidaPaulista in the city of Silo Paulo. Another research was carried out involving non-probabilistic sample with micro-businesses from various segments in the city that were chosen for their accessibility. From the results, product characteristics were elaborated, pricing, and distribution, that compose the application analyses of the marketing tools for micro-businesses and theoretical evolution have stemmed from the bibliographical research as well as field research and observational studies by the authors of the article. The goal is not to exhaust the topic nor to construct a Marketing Plan, but rather to contribute to the discussion, learning, and use of a marketing mix in the segment of micro-enterprises in a more assertive manner. It was concluded that there is no doubt as to the importance of micro-enterprises for any country. His contribution lies mainly in optical innovation and creativity because these companies can test new models of work, management, products, and services. It should be noted that micro-enterprises are greatly responsible for job generation in our country, denoting their prominent social and ecological perspective. More than a transient way of earning money, the reality of micro-enterprises should be considered as a social and economic phenomenon capable of generating regional and, consequently, global growth.     

Consistency between Sakernas and the IFLS for Analyses of Indonesia’s Labour Market: A Cross-Validation Exercise

This article assesses the consistency between Indonesia’s National Labour Force Survey (Sakernas) and the Indonesia Family Life Survey (IFLS) for analyses of the country’s labour market. I show that Sakernas and the IFLS depict different levels of and changes in labour-market indicators. My estimates of the labour-force participation model, the sector-choice model, and the Mincer model are all statistically different between the two surveys, although the magnitudes are similar for labour-force participation and sector choice. The IFLS shows a much higher return to education than Sakernas, according to the Mincer model. In addition, I find that the cross-sectional sample of the IFLS and the panel sample of the IFLS corrected for attrition yield similar coefficient estimates from all equations. The findings in this article provide an important reference for researchers interested in using Sakernas and the IFLS—either individually or combined—to analyse labour-market issues in Indonesia.
