Equilibrium interest rate and liquidity premium with transaction costs   总被引:5,自引:0,他引:5  
Summary. In this article we study the effects of transaction costs on asset prices. We assume an overlapping generations economy with two riskless assets. The first asset is liquid while the second asset carries proportional transaction costs. We show that agents buy the liquid asset for short-term investment and the illiquid asset for long-term investment. When transaction costs increase, the price of the liquid asset increases. The price of the illiquid asset decreases if the asset is in small supply, but may increase if the supply is large. These results have implications for the effects of transaction taxes and commission deregulation. Received: December 5, 1997; revised version: March 19, 1998  相似文献

For worldwide fisheries production, two major trends emerge for the next decades: a significantly larger role for aquaculture and reduced output due to climate change impacts. While the former leads to an increase in cost, the latter affects natural regeneration. To address both impacts, we investigate the relevance of resource extraction costs for a private property fishery in an intertemporal general equilibrium model with capital accumulation, commodity production and a labor market. We show how the extraction cost parameter—in addition to time preference, technology and natural regeneration—matters for the existence (and stability) of an economically feasible, nontrivial stationary state. Higher extraction costs increase the equilibrium resource stock, while a reduced regeneration rate (e.g. due to climate change) decreases the stock. Moreover, resource extraction overshoots its new equilibrium value after the cost shock while after a regeneration shock extraction levels adjust monotonically towards the new equilibrium.  相似文献

We introduce differential information in the asset market model studied by Cheng J Math Econ 20(1):137–152,1991, Dana and Le Van J Math Econ 25(3):263–280,1996 and Le Van and Truong Xuan J Math Econ 36(3): 241–254, 2001. We prove an equilibrium existence result assuming that the economy’s information structure satisfies the conditional independence property. If private information is not publicly verifiable, agents have incentives to misreport their types and therefore contracts may not be executed in the second period. We also show that under the conditional independence property equilibrium contracts are always executable.  相似文献

This paper analyzes the use of a cost-free reward mechanism in the exploitation of a common property resource. We implement an experimental study involving a two-stages game where agents first decide resource appropriation and then have the opportunity to distribute cost-free bestowals. We observe that subjects link the two activities in such a way that appropriation determines the distribution of bestowals which in turn contributes maintaining low appropriation levels, thus avoiding the destruction of the common resource. Not all the potential bestowals are distributed, however.  相似文献

This paper aims to demonstrate that the strategic approach to link formation can generate networks that share some of the main structural properties of most real social networks. For this purpose, we introduce a spatialized variation of the Connections model [Jackson, M.O., Wolinsky, A., 1996. A strategic model of social and economic networks. Journal of Economic Theory 71, 44–74] to describe the strategic formation of links by agents who balance the benefits of forming links resulting from imperfect knowledge flows against their costs, which increase with geographic distance. We show, for intermediate levels of knowledge transferability, clustering occurs in geographical space and a few agents sustain distant connections. Such networks exhibit the small world property (high clustering and short average relational distances). When the costs of link formation are normally distributed across agents, asymmetric degree distributions are also obtained.  相似文献

产权、代理成本和代理效率   总被引:53,自引:2,他引:51

本文选择政府管制较少、竞争较为充分的电子电器行业作为研究对象,考察了产权制度与代理成本和代理效率的关系,得到以下结论:(1)在代理成本上,国有产权企业普遍高于混和产权企业,混和产权企业高于个人产权企业;在代理成本差异上,混和产权企业与个人产权企业的差异小于与国有产权企业的差异。(2)长期投资率和职工人数与代理成本呈显著正相关关系,而长期投资率、财务杠杆比率、职工人数等与代理效率呈显著负相关关系。(3)企业规模越大,不同产权的代理成本差异越小;反之代理成本差异越大。(4)随着市场竞争程度的提高,各类产权企业的代理成本都呈现下降趋势,其代理效率呈现提高趋势。我们研究的启示是国有企业改革的突破口应考虑如何降低其代理成本,解决的措施之一是产权改革,尤其是产权多元化的改革,其次是完善对投资和负债及冗员的监督和控制机制,以促进代理成本的降低和代理效率的提高。  相似文献

We introduce a dynamic model of resource-grabbing by status-conscious agents, i.e., agents value not only their absolute consumption levels, but also the relative status within their reference group. We explore the effect of the concern for relative consumption on the growth rate and the welfare of an economy where agents appropriate from a common property resource. Our model shows that the greater is agents' concern about their relative status, the more aggressively they tend to behave. Consequently, social welfare is lower because the growth rate of the public asset is reduced due to higher extraction rate. We also consider the effect of increased heterogeneity, and show that social welfare decreases as the distribution of status-consciousness among agents widens.  相似文献

Access Regulation and the Timing of Infrastructure Investment   总被引:3,自引:0,他引:3  
This paper examines infrastructure investment incentives under a system of 'regulation by negotiation'. We demonstrate that an appropriately specified access pricing rule can induce private firms to choose to invest at a socially optimal time. The optimal regulatory regime allocates investment costs to the access provider and seeker based on their relative use-values of the facility. It is superior to an unregulated environment because it commits firms ex ante to an access charge that allows for sunk cost recovery. In addition, we show that when the time that access is sought is flexible both replacement- and historical-cost asset valuation methodologies can lead to optimal investment incentives. However, when seeker timing is restricted, historical cost can give rise to distorted incentives.  相似文献

We analyze the effects of strategic behavior and private information in pollution permit markets in which all firms have market power. The market is characterized by supply-function equilibria. Firms submit net supplies for permits and a market maker determines the market-clearing price. Net supplies depend on abatement cost functions, which in turn depend on private information parameters. We calculate the increase in aggregate abatement costs due to strategic behavior and private information and show that private information attenuates the effects of strategic behavior.   相似文献

We show that a seemingly paradoxical result is possible—an increase in one's wage can reduce one's welfare. Such outcome can occur in an economy populated by agents who value a private good bought using labor income and a public good produced by voluntary time contributions. A raise in the wage (in general, opportunity cost of time) makes each agent substitute away from contributing to the public good, failing to internalize the negative externality imposed on others. The result is a decrease in public good provision. Under quite general conditions, the implied cumulative negative effect on agents' welfare can more than offset the positive effect of the wage raise from increased private good consumption and lead to an equilibrium in which all agents are worse off. Our result is particularly relevant for developing economy settings as it holds for relatively low initial wage levels. We discuss the applicability of our findings to a number of important problems in development, such as market integration, cooperation in common pool resource conservation and social capital.  相似文献

This paper extends the Dornbusch model of overshooting exchange rates to discuss both exchange rate and output effects of capital controls that involve additional costs for International asset transactions.We show that, on the one hand, such capital controls have the merit of reducing the volatility of exchange rate volatility in the sort run and induces costs for the real sector in the form of lower equilibrium output levels.

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The experimental design extends the Bala–Goyal [Bala, V., Goyal, S., 2000. A non-cooperative model of network formation, Econometrica 68, 1131–1230] model of network formation with decay and two-way flow of benefits by introducing agents with lower linking costs or higher benefits to others. Furthermore, agents' types may be common knowledge or private information. In all treatments, the (efficient) equilibrium network has a “star” structure. While equilibrium predictions fail completely with homogeneous agents, star networks frequently occur with heterogeneous agents. Stars are not born but rather develop: with a high-value agent, the network's centrality, stability, and efficiency all increase over time. A structural econometric model based on best response dynamics and other-regarding preferences is used to analyze individual linking behavior. Maximum-likelihood estimates of the underlying structural parameters, obtained by pooling data from several treatments, allow us to explain the main treatment effects.  相似文献

Private agents make large contributions to networks of conserved land, but little is known about how private agents’ decisions might be altered by government actions. This paper explores the impact of public conservation and public policy on the quantity and configuration of private land conservation and the extent to which the social optimum is reached. Because land conservation benefits often have thresholds and spatial characteristics, we consider the impact of different land conservation benefit functions on the patterns of conservation created by the interaction of private and public agents. We find that public conservation crowds private conservation in or out depending on whether marginal conservation benefits increase or decrease with total acreage, and crowding out is mitigated by the presence of budget constraints. We show how land conservation agents might interact strategically in space depending on preferences over fragmentation, and we explore that spatial strategic interaction in a case with a regional land trust and a case with hot-spot parcels. We identify when government policies, such as agglomeration bonuses and mitigating coordination costs, are most likely to increase the social benefits provided by private land conservation agents.  相似文献

This paper examines the contribution of administrative and procedural transaction costs to economic growth under common legal system. We show that administrative and procedural costs vary quite a lot even within the institutional environment sharing the common legal system. States with low‐cost business registration, low‐cost access to property rights and greater judicial efficiency tend to have consistently higher growth. The established effects are robust to alternative model specifications, heterogeneity bias, and to a variety of control variables that might confound the effects of administrative and procedural costs on growth. Such differences in costs are far from being trivial as we show that these within‐system differences might be instrumental in influencing economic growth. Lower administrative and procedural costs induce growth by increasing investment rate, lowering unemployment rate, encouraging labor supply and improving total factor productivity. In the counterfactual scenario, the transition from high‐cost to low‐cost regime is associated with substantial growth and development gains over time. By exploiting the variation in the disease environment, ethnic fractionalization and historical urbanization, we show that the negative effect of rising procedural and administrative costs on growth and development appears to be causal.  相似文献

Laffont and Tirole (1987) analyzed the problem of a regulator that wants to select one ofn firms to carry out a single indivisible project when the firms have private and independent costs and have the possibility of an ex-post investment in (non-observable) effort to reduce the (observable) cost.This paper generalizes the analysis to a model of common costs, unknown at the bidding stage, while keeping the assumption of independent types. I show that the main characteristics of the private costs model are kept in a common cost framework. I provide two mechanisms that may be used to implement the optimal contract.This is a much revised version of a part of chapter one of my Ph.D. dissertation. I would like to thank Drew Fudenberg, Oliver Hart, and two anonymous referees for their comments. I am especially indebted to Jean Tirole, who suggested this problem to me. I have also benefited from presentations at MIT and the EARIE 93 Meeting. Financial support from INVOTAN (grant 3/88/PO) is gratefully acknowledged. Remaining errors are my own.  相似文献

Asset Prices and Trading Volume in a Beauty Contest   总被引:1,自引:0,他引:1  
Speculators buy an asset hoping to sell it later to investors with higher private valuations. If agents are uncertain about the distribution of private valuations and about the beliefs of others about this distribution, a beauty contest with an infinite hierarchy of beliefs arises. Under Harsanyi's assumption of a common prior the infinite beliefs hierarchy is readily solved using Bayes' law. This paper shows that common knowledge of the "beliefs formation rule," mapping the private valuation of each gent into his first-order belief, also simplifies the beliefs hierarchy while allowing for disagreement among agents. We analyse the resulting speculation in a stylized asset market. Several statistics, computed only from readily observable quote, return and volume data, are evaluated in terms of their power to discriminate between genuine disagreement and the Harsanyian case. Only statistics that relate volume and volatility, or volume and changes in best offers, have the necessary discriminatory power.  相似文献

We build a subgame perfect Nash equilibrium of a common property productive asset oligopoly and analyze separately the impact of a change in the implicit growth rate of the asset and a change in the number of firms exploiting the asset. We show that the steady state level of asset can be a decreasing function of the asset's implicit growth rate. This phenomenon arises when the initial stock of asset is below a certain threshold. In the short-run we show that firms’ exploitation rate can be a decreasing function of the implicit growth rate. We study the impact of a change in the number of firms that share access to the asset. Reducing the number of firms can result, in the long-run, in higher industry production. In the short-run, it can result in an increase of the industry's exploitation and a decrease of the level of the asset's stock.  相似文献

Inflation, Inflation Variability, and Corruption   总被引:2,自引:0,他引:2  
We present a model where agents can inflate the cost of goods needed to start an investment project and inflation variability increases monitoring costs. We show that inflation variability can lead to higher corruption and lower investment. We document a positive relationship between corruption and inflation variability in a sample of 75 countries. The effect is robust to the inclusion of country fixed effects, other controls, and 2SLS estimation. The results are economically significant: a one standard deviation increase in inflation variance from the median increases corruption by 12 percent of a standard deviation and reduces growth by 0.33 percentage points. Our paper highlights a new channel through which inflation reduces investment and growth, thus bridging the perception gap over the costs of inflation between economists and the public. We also find evidence that political competition reduces corruption and that corruption is pro-cyclical.  相似文献
