In a business cycle model that incorporates a standard matching framework, employment increases in response to news shocks, even though the wealth effect associated with the increase in expected productivity reduces labor force participation. The reason is that the matching friction induces entrepreneurs to increase investment in new projects and vacancies early. If there is underinvestment in new projects in the competitive equilibrium, then the efficiency gains associated with an increase in employment make it possible that consumption, employment, output, as well as the investment in new and existing projects jointly increase long before the actual increase in productivity materializes. If there is no underinvestment, then investment in existing projects decreases, but total investment, consumption, employment, and output still jointly increase.  相似文献

Equilibrium models have been widely used in the literature with the aim of showing theoretical properties of emissions trading schemes. This paper applies equilibrium models to empirically study permit prices and to quantify the permit price sensitivity. In particular, we demonstrate that emission trading schemes both with and without banking are inherently prone to price jumps.  相似文献

During the past thirty years, central banks often intervened in foreign exchange markets. Sometimes they carried out foreign exchange market interventions on a unilateral basis. However, central banks often coordinated their foreign exchange market interventions. We develop a quantitative reaction function model that renders it possible to study the factors that made central banks switch from unilateral to coordinated interventions. We apply our model to the intervention policies of the Japanese monetary authorities and the U.S. Federal Reserve in the yen/U.S. dollar market during the period 1991–2001. To this end, we use recently released official data on the foreign exchange market interventions of the Japanese monetary authorities. JEL no. F31, F33, G14, G15  相似文献

We study experimental two-sided markets in which the information structure is endogenous. When submitting an offer, a trader decides which other traders will be informed about the offer. This setup allows both a decentralized bargaining market (Chamberlin, J. Polit. Econ. 56 (1948) 95), and a double auction market (Smith J. Polit. Econ. 70 (1962) 111) as special cases. The results show that offers are typically directed to all traders of the other side of the market, but to none of the traders of the same side of the market. Even though traders receive much less information, the resulting market institution leads to the same outcomes in terms of prices and efficiency as a double auction market. In two additional treatments we examine the robustness of these results. First, it is found that the market institution adapts predictably, but not necessarily efficiently, to the imposition of transaction costs. Second, we find that the preference of sellers to conceal offers from competitors is strict. At the same time, sellers benefit collectively when they reveal offers to each other.  相似文献

While the literature on the economic impacts of major sports events has grown considerably over the years, the question of utilisation of venues built for these events after the party is over has received little attention. This article fills some of the gaps in the literature. By means of a Stadium Utilisation Index, it measures the post-event utilisation of venues that were constructed of significantly refurbished to host major sports events in the period from 1996 to 2010. It reveals some of the challenges facing the utilisation of the venues once ‘the circus has left town’. The regressions identify that private owned stadiums have a higher rate of utilisation than publicly built venues. The stadiums with the highest capacity tend to have higher utilisation. Last, but not least in terms of importance, stadiums in nations with a high degree of corruption had the lowest utilisation.  相似文献

The aim of this study is to investigate the effects of planning and control on the performance of new product development (NPD) projects. It is hypothesized that (1) thorough business planning at the beginning of a project creates a basis for proficient project and risk planning; (2) the proficiency of project planning, risk planning, and process management activities each improves innovation performance directly; (3) the relationship of planning and success is mediated by process management; and (4) the strength of these relationships is moderated by uncertainty, as determined by the degree of innovativeness. To test the hypotheses, data from 132 NPD projects were collected and analyzed. A measurement model was used to establish valid and reliable constructs, a path model to test the main effects, and a multiple-moderated regression analysis for the moderator hypotheses. The results suggest that the proficiency of project planning and process management is important predictors of NPD performance. Specifically, project risk planning and goal stability throughout the development process are found to enhance performance significantly. Business planning proves to be an important antecedent of the more development-related planning activities such as project planning and risk planning. Additionally, the results lend support to the hypotheses regarding the mediating role of process management in the planning–performance relationship. Project planning and risk planning support the quality of process management and thus impact NPD performance indirectly. Only to a limited extent are the strengths of these relationships moderated by the degree of innovativeness of the NPD project.  相似文献
