生态系统服务测度下市域生态空间管控体系构建

生态空间承载着人类、动植物和自然生态多种过程，是生态系统服务功能的策源地和枢纽区。以实施生态空间管控为导引，借助多源数据和ArcGIS、C-Plan系统工具，核心应用系统保护规划(SCP)技术，建立生态服务测度下市域生态空间管控体系的构建方法。基于此，以哈尔滨为例，以不可替代性为表征实现生态空间测度指标综合与功效评价，构建生态空间关键区识别、功能区优划以及网络格局优化模型，提出“重点保护-分区指引-格局优化”的市域生态空间管控体系，为新型城镇化及绿色发展战略的实施奠定科学基础和提供技术支撑。     

Does too much government spending depress the economic development of transition economies? Evidences from dynamic panel threshold analysis

This paper investigates the relationship between government size and economic growth and determines the optimal level of government spending to maximize economic growth. The paper applies a dynamic panel data analysis based upon a threshold model to test the threshold effect of government spending in 26 transition economies over the period spanning 1993–2016. According to the analysis results, government expenditures have a threshold effect on economic growth, and there is a non-linear relationship depicted as an Armey curve in these transition economies. The findings indicate that a government size above the threshold government spending level adversely affects economic growth, while a government size below the threshold level has a positive effect. Furthermore, there is a statistically significant relationship between the two variables above and below that optimal level, even if we divide the sample into developed and developing countries. Our findings suggest that governments in transition economies should consider optimal government size at around the estimated threshold level to support sustainable economic growth.     

Partial International Coordination in the Great Fish War

This study extends the great fish war model of Levhari and Mirman [Levhari, D. and Mirman, L. (1980) Bell Journal of Economics 11: 322–344] by incorporating a multiple country context into the model and investigates the existence of a partial coordination Nash equilibrium. First, findings of this paper suggest that a partial coordination scheme is sustainable only in limited cases. Any coalition that has more than two member countries cannot be sustained. Second, the existence and the number of coordinating countries depend critically on the magnitude of the biological and preference parameters. Finally, if the coalition is assumed to be a dominant player, there always exist one or two welfare-improving sustainable coalitions and the size of the sustainable coalitions depends on the parameters of the problem.     

信任、不信任与控制关系及其应用研究的现状与思考

信任、不信任与控制之间的关系及其应用,已成为当代众多社会科学学科研究信任问题的子焦点之一。我们依据近年国外有关文献的调研,认为：缺乏一个以当代众多社会科学领域重要的理论命题为基础的、统一的科学、严谨、结构合理的三者关系的分析框架,是当前深化和推进有关研究必须克服的一个障碍。     

论我国饭店的等级划分与价格管理

在现实市场中,为了方便对酒店进行监督和管理,也为了不同层次消费者的需要,政府往往根据不同的硬件设施标准和软件服务水平对酒店进行等级划分;同时,由于我国旅游市场的外部性因素,政府又根据相应的标准对其进行一定的价格管制, 实行限价,藉此保护消费者,但是这会对消费者和经营者产生影响。     

改善劳动力市场管制的几个问题探讨

对劳动力市场的管制是政府监管市场的一个重要方面。本文通过对目前我国劳动力市场建设及运行、管制中存在的主要问题的分析,探讨了放松对劳动力市场的管制及管制的着力点。笔者认为,政府放松对劳动力市场管制是劳动力市场运行规律及WTO规则的要求,而管制的着力点应主要放在强化制度供给、弥补市场失灵、保护劳动者的合法权益等方面。     

Public policies as specification errors

Treating public policies as computable dynamic general equilibrium model specification errors offers computational and conceptional advantages for comparing models with data. The set of policies calculated to rationalize observed behaviors raises the substantive economic question whether, in any particular market, actual public policies sufficiently coincide with the model's behavior-rationalizing policies, or whether the model offers correct hypotheses about the determinants of demand and supply. As illustrations, public policies are calculated to rationalize, with respect to the stochastic neoclassical growth model, capital market behavior since WWII and labor market behavior in 1929–1950. One conclusion is that capital taxation drives a wedge between consumption growth and the expected pre-tax capital return, in the direction and amount predicted by the theory, and that capital taxation is the major intertemporal distortion in the postwar capital market. Second, a good theory of the Great Depression labor market must explain why measured MRS and MPL diverged so dramatically in 1929–1933 and why the wedge persisted.     

The optimal portfolio for the two-pillar mandatory pension system: the case of Poland

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying.     

Consistency and optimality in a dynamic game of pollution control II: Monopoly

This paper continues a line of research begun in Batabyal (1995a). I model the interaction between a regulator and a monopolistic, polluting firm as a Stackelberg differential game in which the regulator leads. The firm creates pollution, which results in a stock externality. I analyze the intertemporal effects of alternate pollution control measures. The principal issue here concerns the dynamic inconsistency of the optimal solution. Inter alia, I compare the steady state levels of pollution under optimal and under dynamically consistent policies.
