我国报业集团跨媒体经营研究

报业跨媒体经营是指报业企业为了充分利用自身的资源,开发并涉足其他诸如图书、杂志、广播电视、网络等媒体市场。随着我国报业集团化进程的快速发展,报业集团跨媒体经营的步伐也在加快。跨媒体经营既可以通过单体繁殖实现,也可以通过资本运作实现,但无论哪种方式都不能理所当然地被认为,跨媒体经营是传统媒体实现可持续发展的万金油。文章利用经济学原理分析了我国报业集团跨媒体经营的动因以及目前报业集团跨媒体经营存在的问题,并提出了针对性的政策建议。

On optimality in intergenerational risk sharing

Summary. This paper defines and studies optimality in a dynamic stochastic economy with finitely lived agents, and investigates the optimality properties of an equilibrium with or without sequentially complete markets. Various Pareto optimality concepts are considered, including interim and ex ante optimality. We show that, at an equilibrium with a productive asset (land) and sequentially complete markets, the intervention of a government may be justified, but only to improve risk sharing between generations. If markets are incomplete, constrained interim optimality is investigated in two-period lived OLG economies. We extend the optimality properties of an equilibrium with land and give conditions under which introducing a pay-as-you-go system at an equilibrium would not lead to any Pareto improvement.

Government Deficit, Public Investment, and Public Capital in the Transition to an Aging Japan

This paper examines the effects of government deficits, public investment, and public capital on welfare in the transition to an aging Japan by applying a simulated general equilibrium growth model. One of the main results of this paper is that targeting only high economic growth would mislead us as to economic policies, and that a policy to reduce future government deficits is most preferable for almost all generations, even though a cut in future deficits must be followed by a decrease in public investment, thus a decrease in public capital in the future.

大众传媒的企业与产业特征

大众传媒是一种利益组织,它的硬件、运转和发展都必须有资金作后盾。大众传媒的企业化组织、规模生产、产品商品化和企业化管理等都说明大众传媒具有明显的企业特征。从运作模式、产品用途、生产规模等方面考察,大众传媒也已经具备了明显的产业特征。大众传媒产业主要是生产信息或知识产品,它是社会价值与经济价值的统一体,是精神生产与物质生产的统一体,是受众市场与广告市场的统一体,是垄断经营与竞争经营的统一体,是重复生产与变化生产的统一体。     

论信息配置和传媒运作与老工业基地振兴

Overlapping Generations or Infinitely-Lived Agents: Intergenerational Altruism and the Economics of Global Warming

Do we need an overlapping generations model for the economics of global warming? To answer this question, an infinitely-lived agent (ILA) approach and an overlapping generations (OLG) model are contrasted. ILA and OLG can be viewed as polar representations of intergenerational altruism. With ILA an immortal agent acts through his investment/savings decisions as trustee on the behalf of the future generations. With OLG, agents need not behave altruistic. They simply save during working years and dissave completely during retirement. Nevertheless, ILA and OLG must not differ in their implication for greenhouse policy. Greenhouse gas abatement is a straightforward alternative to physical capital formation and, even without altruism, each age cohort has an incentive to provide current abatement in order to reduce future damages attributable to climate change. Indeed, under reasonable assumptions and parameter values, our simulations reveal such an invariance result. Provided carbon taxes are the only policy tool and tax revenues are recycled through socially mandated rules, projections of economic growth, climate change and energy consumption are only insignificantly affected by the choice of approach.     

Perpetual youth and endogenous labor supply: A problem and a possible solution

In the “perpetual youth” overlapping-generations model of Blanchard and Yaari, if leisure is a “normal” good then some agents will have negative labor supply. We suggest a solution to this problem by using a modified version of Greenwood, Hercowitz and Huffman’s utility function. The modification incorporates real money balances, so that the model may be used to analyze monetary as well as fiscal policy. In a Walrasian version of the economy, we show that increased government debt and increased government spending raise the interest rate and lower output, while an open-market operation to increase the money supply lowers the interest rate and raises output.
