In this paper, we develop an explanation for why events in one market may trigger similar events in other markets, even though at first sight the markets appear to be only weakly related. We allow for escape dynamics in each market, and show that an escape in one market is contagious because it more than doubles the probability of a similar escape in another market. We claim that contagion is strong since escapes become highly synchronised across markets. Spillovers are weak because the instantaneous spillover of events from one market to another is small. To illustrate our result, we demonstrate how a currency crisis may be contagious with only weak links between countries. Other examples where weak spillovers would create strong contagion are various models of monetary policy, imperfect competition and endogenous growth. 相似文献

This paper shows that in the Diamond (1965) overlapping generations economy with production and capital savings, there is a period-by-period balanced fiscal policy supporting a steady state allocation that Pareto-improves upon the laissez-faire competitive equilibrium steady state (whether dynamically inefficient or efficient) without resorting to intergenerational transfers. The policy consists of taxing linearly (or subsidizing, in the dynamically efficient case) the returns to capital, while balancing the budget period by period through a lump-sum transfer (or tax, respectively) in second period. This intervention grants every generation the highest steady state utility attainable through markets (i.e. remunerating factors by their marginal productivities and without transfers) which under laissez-faire is not a competitive equilibrium outcome. A transition from the competitive equilibrium steady state to this other steady state is also Pareto-improving when the former is dynamically inefficient. The result disentangles from redistributive considerations the impact of the taxation of capital returns on steady state welfare, and thus provides a rationale for the taxation of capital returns that is based on efficiency considerations and not on redistributive goals. 相似文献

We analyse why the Chinese government sets restrictions on foreign direct investment (FDI). We focus our analysis on the percentage of shares in relocated firms that the government allows to be foreign‐owned. The government's decision on this percentage depends on the entry cost, the number of firms that relocate and the weight of the consumer surplus in the objective function of the government. We show that by its choice of this percentage, the Chinese government may restrict or encourage FDI to its country. We also find that if the government may subsidise the fixed entry cost, it provides a subsidy only when the producer surplus has a greater weight than the consumer surplus in weighted welfare. In that case, the subsidy encourages relocation by both firms and permits the government to allow a lower percentage of shares to be foreign‐owned in relocated firms. 相似文献

Studies have focused heavily on money in the transmission mechanism of monetary policy. In this article we explore the empirical importance of credit. The paper provides a framework in which to analyse the balance sheets of, and financial flows between, different sectors of the UK economy, and an econometric model of the interactions between non-financial firms, households and credit offered by banks and non-bank financial intermediaries. The paper also provides a dynamic structural model of bank and building society credit, money and decisions to consume and invest and then adds credit from non-bank financial intermediaries. Our bottom line is that credit is an important part of the transmission process of UK monetary policy. 相似文献

This paper examines how real estate appreciation correspondingly changes collateral value, which affects debt structure choices and consequent operating decisions. Specifically, we explore whether collateral-based financing provides a link between real estate values and corporate cost behavior. Our baseline results show that an appreciation of a firm’s real estate assets alleviates its cost stickiness. A further analysis shows that this influence is stronger for firms with less prior bank debt, less dependence on external financing, and a lower leverage ratio. We also observe that the impact of collateral shocks on cost stickiness is more pronounced when selling, general and administrative (SG&A) costs create less future value for mature firms and for firms with weaker external governance. Collectively, our results support the argument that an increase in bank debt arising from collateral value appreciation mitigates agency problems and thus lessens cost stickiness. 相似文献

Traders pay attention to one another but are unable to perfectly deduce each others’ beliefs from transactions alone. This explains why markets are hard to beat and also why trading occurs at all. Even when traders react rationally to the actions of others, they cannot arrive easily at a common posterior assessment of value. We model a realistic market composed of traders who combine their own private information with rational learning about the information possessed by others. We compare phenomena in this market with an otherwise identical market populated by traders who receive the same private information but ignore other traders. Using simulation to engender greater realism, we find that learning usually reduces volatility, increases the accuracy of the market price as a forecast of value, reduces trading volume, and decreases the prevalence of bubbles. However, for some combinations of market conditions, learning can have the opposite effect. The marginal influences of eight different market conditions, ranging from information heterogeneity through resource diversity, are estimated. Prices, volatility, volume, and bubbles exhibit subtle and complex responses to market conditions. 相似文献

In this study, we examine the relation between chief executive officers' (CEOs') general managerial skills and firms' risk-taking behaviour. We find that generalist CEOs are associated with significantly higher firm risk, with the association decreasing significantly with CEO tenure. We propose the following managerial skills transformation explanation: the longer a CEO stays with a firm, the less general and more firm specific the CEO's skills and knowledge become; therefore, any effect of the CEO's general managerial skills only appears in the early years of tenure. 相似文献

政府的制度安排服从于收益最大化目标是个动态优化的过程,它决定了国有银行绩效目标由社会目标优先逐步向自身绩效优先的转化。由于中央政府对公有产权保护的内在倾向性,强制性变迁方式下市场机制发育的不足,以及地方政府、国有银行本身以及国有企业等利益集团的利益约束等,政府具有对次优制度安排的选择偏好。最终国有银行制度安排的优化取决于外部环境的建设和政府市场角色的理性回归。 相似文献
