农村居民健康支出与人均纯收入的相关性分析——以吉林省为例

农村人力资本的投资与农民收入的关系一直是学术界研究的重点,本文以农村居民健康支出为例,截取吉林省2000-2009年农村居民健康支出与农民人均收入的数据,对两者进行了一元线性归回分析,证明两者存在正向相关性,即农村居民家庭健康支出对农民人均纯收入有显著正向相关性影响,即在一定程度上,增加农村居民家庭健康支出,会较大程度的促进农民人均纯收入的增长。     

An evaluation of the management of the Finnish employment service

This paper analyses the efficiency of the Finnish Employment Service's management in selecting unemployed individuals who are offered a job. The database used considers short-term unemployed individuals who face the same labour market conditions in 1996. Duration analysis with a Weibull model has been performed in order to study the determinants of the transition probability from unemployment into employment and the impact of receiving job offers through the Employment Service (ES). In order to carry this out, it has been taken into account that the reception of such job offers may be endogenous because the ES selects the individuals who will receive the offers. The empirical results suggest that the decisions made by the ES are adequate in the sense that they increase the benefit of society, compared with a random assignment of the vacancies offered through the ES. Moreover, the effects of the other determinants depend on whether the individual receives offers. The results also point out that individuals who receive no offers through the ES are more likely, as time passes by, to be discouraged in searching for a job than those who do.     

Convergence and divergence in Latin America, 1970-1998

This paper examines the process of convergence in Latin America over the period 1970–1998. There has been relatively little work on income convergence among developing countries in general and in Latin America in particular, even though many studies have examined convergence both within and among developed countries. There is little support for the convergence hypothesis over the sample period as a whole - although the beta coefficient is positive, it is insignificant. Convergence is strong in the 1970s but by the 1990s it has disappeared. There is no evidence of a narrowing in the cross-country dispersion of income (sigma convergence) for the sample period as a whole. The results offer little support for the neo-classical growth model - poorer countries have not grown faster than richer ones. There is a strong case for strengthening regional development policy.     

Consumer welfare effects of increased food and energy prices

In this study, the authors evaluated how much price changes in food and energy – two basic living expenditures competing for consumers’ budgets – would affect consumer welfare. We first estimated a US complete demand system to quantify the interdependent demand relationships among 11 categories of consumption expenditures. Among the estimates, the own price elasticities of both food and energy are relatively inelastic, a finding that explains the dynamics of the recent soaring food and energy prices. The estimated demand elasticities were then incorporated into the measurement of Hicksian compensating variation to analyse the consumer welfare effects of price changes in food and energy. The results indicated that an increase in food and energy prices would increase compensated expenditures or incur a substantial consumer welfare loss, creating an especially heavy burden for low income households.

Gender organizing in China: a study of female workers' representation needs and their perceptions of union efficacy

This paper investigates gender organizing in China from the perspective of women employees in different industrial sectors and across ownership forms. It identifies women workers' views on their representation needs, level and effect of trade union activities, their related attitude towards unionism as well as alternative forms, if any, of organizing. The study reveals that women employees in government organizations, public sector, state-owned enterprises and private firms have significantly different needs and levels of identification with the union. It argues that the pluralism of employment relations in China across the spectrum of ownership forms and occupational groups should be given more recognition and attention than has been warranted.     

Welfare Effects of Endogenous Information Acquisition and Disclosure in Duopoly Markets

Abstract

This paper investigates the interaction between firms' information acquisition decisions and disclosure of internally acquired information in a Cournot duopoly market under demand uncertainty. The main results are as follows. When the correlation between firms' demands is positive and sufficiently high, disclosure of information on demand uncertainty can enhance social welfare, given that the quality of firms' private information is constant. However, in the setting where firms' private information is endogenously determined, mandatory disclosure is not always desirable. This is because, when disclosure is mandated, firms acquire less precise information compared with the case where the acquired information is not disclosed; hence, their internal information environments are deteriorated. This can lead to unintended consequences such that disclosure regulation decreases social welfare.

南方最优知识产权保护水平与南方企业自主创新

构建了一个扩展的南北贸易模型,讨论了南方知识产权保护的决定因素及其对南北双方福利的影响。在模型中,南方政府内生决定知识产权保护水平,北方厂商内生决定研发投资水平和市场竞争策略,南方厂商内生决定自主创新或模仿。研究发现:南方的最优知识产权保护水平与北方存在差异;当南方厂商模仿北方厂商的技术时,南方执行最严格的知识产权保护对北方福利和南方福利都造成损害;当南方厂商的创新效率较高时,严格的知识产权保护能激励南方厂商进行自主创新、改善南方福利。     

The social value of information on product quality

In the context of a seller with private information about product quality, I show that revelation of information on product quality is sometimes, but not always, socially valuable. When it is socially valuable, there is generally a tradeoff between the acquisition and revelation of finer, but more costly information and the revelation of coarser, but less costly information. As a result, it can be socially optimal for firms to reveal only coarse private information.
