环境公益诉讼,尤其是行政诉讼中,原告适格问题是制度建设的重要事项。欧盟各国以《奥胡斯公约》及欧盟指令为轴心,通过各自的公益行政诉讼制度建设,如民众诉讼制度、制定特别法承认团体的原告适格,或通过扩大传统的利益概念,扩大法保护的对象等不同方式达到扩大原告适格的目的,实现公约所保障的司法参与权,使得司法保障成为环境政策中不可欠缺的制度性手段。  相似文献

This paper first summarises Japan's fiscal policies in the 1990s. Then, we investigate the macroeconomic impact of government debt and the sustainability problem. We find that the Keynesian fiscal policy in the 1990s was not effective and fiscal sustainability may therefore become a serious issue. We also estimate the optimal level of deficits and evaluate fiscal reconstruction movements. It is shown that the actual deficit exceeded the optimal level in the late 1990s. We then inspect fiscal reconstruction movements in the Hashimoto Administration in 1997 and find that the major factor of recession in 1997 was not fiscal consolidation. An important lesson from Japan's fiscal policies in the 1990s is that long‐run structural reform is more important than short‐run Keynesian policy.  相似文献

This study formulates a dynamic mixed oligopoly model, in which a state‐owned public firm competes against a private firm over multiple periods. We adopt a differential game formulated by Fershtman and Kamien [Econometrica 55 (1987), pp. 1151–1164] and investigate how the dynamic competition affects the optimal privatization policy. We characterize the open‐loop Nash equilibrium (OLNE) and Markov‐perfect Nash equilibrium (MPNE). We show that in the MPNE, an increase in the degree of privatization has a nonmonotonic effect on the price, increasing it in a wide range of parameter spaces, which is in sharp contrast to the result in the OLNE or static analyses. We also find that the optimal degree of privatization is higher in the MPNE than that in the OLNE and static equilibrium. These results suggest that intertemporal strategic behavior changes the optimal privatization policy.  相似文献

We revisit the relationship between the optimal privatization policy and market competition indexes such as the Hirschman–Herfindahl index. It is affected by the number of the firms and asymmetry among the sizes of the firms; the smaller the number of firms and the more asymmetry among firms, the higher the market concentration index. The literature on mixed oligopolies suggested that the optimal degree of privatization increases with the number of private firms, and thus, decreases with the market competition index, assuming that all private firms are homogeneous. We investigate how asymmetry among private firms affects the optimal degree of privatization. We propose the simplest and natural model formulation to discuss asymmetry among private firms. We find that the optimal degree of privatization is either nonmonotone or monotonically increasing, and thus never monotonically decreasing, in asymmetry among private firms.  相似文献

We formulate an international oligopoly model in the presence of global common ownership. We theoretically investigate how common ownership affects the volume of international trade in an oligopoly market and global welfare. We find that welfare decreases (increases) with the degree of common ownership when the international transport costs are low (high), whereas common ownership reduces international trade. This conclusion remains valid in the presence of import tariffs and asymmetric common ownership share.  相似文献

We investigate endogenous timing in a mixed duopoly in a differentiated product market. We find that private leadership is better than public leadership from a social welfare perspective if the private firm is domestic, regardless of the degree of product differentiation. Nevertheless, the public leadership equilibrium is risk-dominant, and it is thus robust if the degree of product differentiation is high. We also find that regardless of the degree of product differentiation, the public leadership equilibrium is risk-dominant if the private firm is foreign. These results may explain the recent revival of public financial institutions in Japan.  相似文献

Consumption is one channel through which the environment is damaged. To protect the environment, various product standards have been introduced across the world. This paper uses a new economic geography framework to explore the effects of environmental product standards on environment in a North–South trade model. It examines the situation in which the North unilaterally introduces an environmental product standard. Specifically, those products that do not meet the standard are not allowed to be sold in the North's market. It is found that such a standard may worsen the North's environment but improve the South's environment as a result of firm relocation.  相似文献

The paper investigates a three‐country duopoly model. Two developed countries have large markets and one developing country has a cost advantage. The author finds that strategic complementarity in location choice yields multiple equilibria. One is a cost‐oriented agglomeration of firms in the developing country and the other is a market‐oriented equilibrium where each firm locates in its developed home country. Also, private incentives for the cost‐oriented location are excessive (resp. insufficient) from the viewpoint of world welfare if firms choose their locations non‐cooperatively (resp. cooperatively).  相似文献

We investigate how unit (or specific) tax and ad valorem tax affect equilibrium location choice in a model of product differentiation, which includes Hotelling (linear-city) and Vickrey-Salop (circular-city) spatial models as special cases. We find that neither tax affects equilibrium location patterns as long as each firm has the same production cost. Two taxes can yield different location patterns under cost heterogeneity among firms.  相似文献

This paper constructs a consistent set of quarterly Japanese data for the 1960–2002 sample period and compares properties of the Japanese and U.S. business cycles. We document some important differences in the adjustment of labor input between the two countries. In Japan most of the adjustment is in hours per worker of males and females and also in employment of females. In the U.S. most of the adjustment is in employment of both males and females. We formulate, estimate, and analyze a model that makes the distinction between the intensive and extensive margin and allows for gender differerences in labor supply. A weak empirical correlation between hours per worker and employment in Japanese data is a puzzle for our theory.  相似文献
