Government spending, capital accumulation and the optimal policy rule: The role of public service capital

In this paper, we modify the Djajić [Djajić, S., 1987. “Government Spending and the Optimal Rates of Consumption and Capital Accumulation,” Canadian Journal of Economics 20, 544–554.] model in such a way that government consumption expenditure provides utility to households via the total stock of government services rather than the government consumption flow alone. By using such a framework, we show that the optimality condition for the public service capital stock is the marginal rate of substitution between public service capital and consumption that equals the intertemporal marginal rate of transformation between the two goods. In addition, we show that the relationship between private consumption and public service capital in a household's utility plays an important role in determining the transitional behavior of relevant variables. We also examine the second-best government consumption expenditure policy. By contrast, in the standard flow specification, e.g., Turnovsky and Brock [Turnovsky, S.J. and Brock, W.A., 1980. “Time Consistency and Optimal Government Policies in Perfect Foresight Equilibrium,” Journal of Public Economics 13, 183–212.], Ihori [Ihori, T., 1990. “Government Spending and Private Consumption,” Canadian Journal of Economics 23, 60–69.], and Turnovsky and Fisher [Turnovsky, S.J. and Fisher, W.H., 1995. “The Composition of Government Expenditure and its Consequences for Macroeconomic Performance,” Journal of Economic Dynamics and Control 19, 747–786.], the second-best government consumption expenditure is decided on the basis that the marginal utility of consumption is equal to the discounted sum of the marginal utility of the government's flow spending.     

Disease management programs: program intervention, behavior modification, and dosage effect

Disease management programs provide highly personalized self- management support to consumers afflicted with chronic illnesses. Program interventions include the provision of health information, ongoing motivation, and support for behavior change, adherence to pharmacotherapy, development of self-efficacy, and the distribution of self-care tools. Interactions between program and patients are structured and repetitive over time. Consumer behavior change can result in measurable improvements in quality and medical cost savings from postponement or avoidance of preventable complications. We evaluated the impact on cost and quality of a comprehensive Diabetes Disease Management Program (DDMP) across ten US urban markets. A staggered implementation allowed for ten pre–post and five pair-wise comparisons. The DDMP demonstrated significant improvements in six diabetes-related quality indicators, lower cost, and a dose-response with greater than 6 months participation. We conclude that a DDMP improves quality of care and reduce overall medical costs.

The Analysis of Welfare Effects of an Environmental Product Tax: An Application to the Taxation of Car Tyres in Hungary

A sophisticated welfare analysis developed by Morris and Kis (1996) is presented here for the study of the effect of a product charge tax on the car tyre market in Hungary. The analysis is extended and complemented in this paper by, first, using the AIDS model and an algorithm developed by Galarraga and Markandya (2000) to estimate demand elasticities from limited data and, second, including the income effects into the analysis. The latter does not have much impact on the results but the generalisation of the model might be useful for the analysis of different goods where the proportion of income spent on them is more important.     

统一股价指数的必要性及绩效分析

股票指数是投资者分析股市动态,拟定投资策略的重要参考依据,同时也是研究和分析一国政治、经济等情况的重要指标。在我国同时存在沪深两个证券交易所,人为地造成了股票市场的分割,难以形成统一的股票价格指数体系,应尽快编制出全国统一的股价指数,促进我国证券市场的健康发展。

论美国多轨制对外贸易政策的形成与经济效应

20世纪70年代初,经济实力相对衰弱迫使美国对外贸易政策更加务实,构成了美国实行多轨制对外贸易政策的主要原因。实行多轨制对外贸易政策以来,美国经济结构进一步软化和其他国家的贸易摩擦进一步增加。多轨制对外贸易政策的实质是全面的贸易保护,其目的在于保护本国弱势部门,发展本国强势部门,是一种以绝对优势作为制定对外贸易政策基础的贸易管理方式。     

Underwriter Lock-up Releases, Initial Public Offerings and After-market Performance

The lock‐up agreement between an underwriter and an issuing firm's principals prohibits sale of securities for a period of time following the offering date. Investment banks must support the stock following an offering. The lock‐up assures investors that the restricted shares will not enter the market, at least for a period of time. Negative abnormal returns prior to the lock‐up release show that unrestricted investors liquidate positions prior to the scheduled lock‐up release. Negative abnormal returns are more robust for firms that are not influenced by SEC Rule 144 than for firms that are.
