This article revisits the relationship between democracy, liberalization and prosperity in transition countries, using a panel of 25 countries over 20 years. Earlier investigations found political and economic liberalization to be positively correlated although the relationship between political liberalization and prosperity remained unclear. In this article, the results are ambiguous regarding the relationship between democracy indicators by Freedom House and the Polity Project on one hand and growth on the other. This contribution therefore investigates the component variables of these indicators to determine their degree of influence. The findings suggest that basic constitutional rights and constraints on the government rather than political competition as such may be conducive to both economic liberalization and prosperity in the transition countries.  相似文献

Abstract Under congestion pricing, Canadian airports would annually save between $72 and $105 million. Social costs per landing and takeoff decrease about $300 at Toronto and Vancouver and $50 at Calgary and Montreal. Slot constraints fail to eliminate this airport congestion. Congestion prices are lower on average than existing weight‐based prices. Current airport capacity accommodates at least five more years of traffic growth before congestion reaches current levels. Substantial welfare gains occur even if dominant airlines already internalize their self‐imposed delays. This article calculates equilibrium congestion pricing schedules, traffic rates, queuing delays, layover times, and connection times by time of day.  相似文献

We provide new evidence on patterns of structural change in advanced economies, reconsidering the stylised facts put forward by Kaldor (1963) , Kuznets (1971) , and Maddison (1980) . Since 1980, the services sector has overwhelmingly predominated in the economic activity of the European Union, Japan, and the US, but there is substantial heterogeneity among services. Personal, finance, and business services have low productivity growth and increasing shares in employment and GDP. By contrast, shares of distribution services are constant, and productivity growth is rapid. We find that the labour share in value‐added is declining, while the use of ICT capital and skilled labour is increasing in all sectors and regions.  相似文献

In dealing with a transnational pollutant-emitting duopoly welfare-maximising policy makers face two negative externalities: imperfect competition and unpriced emissions. Strategic environmental policy models show that these externalities involve a trade-off between reducing pollution and allowing for rent-seeking of the respective firm. This dilemma usually results in a suboptimal internalisation of the negative externality emerging from emissions. Indeed, the conventional model setup includes an R&D stage that enables the firms to mitigate regulation costs. But the typical one period configuration ignores that R&D expenditures create knowledge capital which is, due to its inherent cumulativeness, also effective in following periods. Our model analyses the established trade-off in a two period setting and therefore allows for an investigation of intertemporal knowledge accumulation. We find that the intertemporal effects provide an incentive for a policy maker to set a higher tax rate compared to a one-period setup which lessens the magnitude of the suboptimal internalisation of emissions. Under certain conditions even a tax rate above the Pigouvian level is possible in period 1.  相似文献

We present a policy game where a Rich country has a higher ability than a Poor country to commit to certain elements of health policy such as providing income related price subsidies and allowing parallel imports (PI). When allowing PI is not a choice for the Poor country, the Rich country allows PI and both countries provide a subsidy to their poorer buyers as the subgame perfect equilibrium policies. However, when the Poor is able to PI a different equilibrium may arise. We show that the ability of the Poor to allow PI might increase welfare in this country even if it is never implemented. We also prove that as the Poor country gets richer, it will not be in their best interest to sign an agreement with the Rich to commit to not allowing PI.  相似文献

Existing models of offshoring are not equipped to explain how global production sharing affects the volatility of economic activity. This paper develops a trade model that can account for why offshoring industries in low wage countries such as Mexico experience fluctuations in employment that are twice as large as in high wage countries such as the United States. We argue that a key to explaining this outcome is that the extensive margin of offshoring responds endogenously to shocks in demand and transmits those shocks across borders in an amplified manner. Empirical evidence supports the claim that the extensive margin of offshoring is an active margin of adjustment, and quantitative simulation experiments show that the degree of movement of this margin in the data is sufficient to explain relative employment volatility in Mexico and the U.S.  相似文献

This paper assesses the impact of stock exchange funding in the Shari'ya compliant Islamic economy of Sudan. Evidence suggests that while Islamic financial instruments have considerable potential in facilitating development finance through their emphasis on partnership this is better achieved by the banking system rather than the Khartoum Stock Exchange. A case study of the Sudan Telecommunications company shows that larger firms able to cross-list elsewhere are likely to choose regional markets in preference to their domestic one thus benefiting from lower costs of equity. However, governance preferences are likely to favour block shareholders following the Islamic finance partnership concept.  相似文献

China's small farmers face increasing challenges because of land and water resource constraints and the effects of climate change. With the strengthened agricultural stimulus policies, poverty reduction and social protection programs, as well as the expanding international food trade, up to now China has achieved food security through small farm agriculture. During intensive economic restructuring, smallholders still coexist with large‐sized farms and industrialized agricultural businesses, but are in a vulnerable position in market transactions. Oriented to 2050, China's agricultural development and food security policies should work to improve domestic market structure, to further release international trade control and to empower smallholders.  相似文献
