Transboundary Marine Resources and Trading Neighbours   总被引:1,自引:0,他引:1  
The importance of space in analyzing issues pertaining to renewable resources can hardly be overstated. Many such resources are mobile and spatially heterogeneous with respect to bio-economic variables, with important implications for both domestic management regimes and for international externalities and policy interactions. This paper uses a simple general-equilibrium framework to show that acknowledging the inter-jurisdictional mobility of a resource such as fish has the potential to alter or qualify some of the conservation and welfare results obtained in the canonical models. The previous literature on trade and renewable resources has focused on cases where national resource stocks are independent. Brander and Taylor (Can J Econ 30(3):526?C552, 1997a; Resour Energy Econ 19(4):267?C297, 1997b; J Int Econ, 1998a; Am Econ Rev, 1998b) find that trade leads to resource stock depletion for an open-access resource-exporting country, while the non-resource exporter is necessarily diversified. In contrast, we find that the country with a comparative advantage in the resource good may gain from a conservation standpoint, while its partner can specialize in the manufactured good and may incur conservation and even welfare losses from trade.  相似文献

We study the long-run properties of a class of locally interactive learning systems. A finite set of players at fixed locations play a two-by-two symmetric normal form game with strategic complementarities, with one of their “neighbors” selected at random. Because of the endogenous nature of experimentation, or “noise,” the systems we study exhibit a high degree of path dependence. Different actions of a pure coordination game may survive in the long-run at different locations of the system. A reinterpretation of our results shows that the local nature of search may be a robust reason for price dispersion in a search model,Journal of Economic LiteratureClassification Numbers: C72, D83.  相似文献

The aim of this article is to present a learning theory (constructivist theory) that supports and explains a lot of the requested changes in entrepreneurship education. It also explains how entrepreneurs learn and serves as a basis for designing entrepreneurship programs. If we look at the 'skills' and competencies of entrepreneurs from a constructivist's perspective we find most of them by observing children under the age of five or six: they are motivated to learn, they are interested in a variety of different topics, they ask excellent questions, they try many things to get insights, they are creative, they are impatient. In short, they create and govern their own learning process, which is open for any content, style, goal, experience, etc., and allows them to take every opportunity to answer the question in concern. In this sense it is similar to the entrepreneurial process where the entrepreneur tries everything and is ready to learn what is needed to be successful.  相似文献

Processing export plays a significant role in international trade. In this paper, focusing on firm-level dynamics, we show that firms learn from their processing export experience to improve their subsequent ordinary export outcomes. Using transaction-level trade data and firm-level production data, we show that firms’ ordinary export performance, at both extensive and intensive margins, is enhanced by their own processing experience. Firms also export products with improved quality after engaging in processing exports of similar products. Furthermore, we investigate potential channels through which firms learn from processing experience. We find that firms potentially learn from processing experience to enhance production efficiency, to better understand how to improve product appeal to cater to specific markets, and to gain better and easier access to inputs. Moreover, we find that exporters benefit more from processing experience for larger markets with fiercer competition. Similarly, stronger learning effects are also observed when processing experience is associated with products that embody less diffused knowledge and are more differentiated. Also, firms learn more from processing experience when they are more actively engaged in processing imports. Lastly, we verify the economic significance and quantify the importance of these potential channels.  相似文献

This paper considers a smooth and noisy version of the statistical prediction model studied in the herding/informational cascades literature and compares market and optimal learning. The latter is characterized by defining a decentralized welfare benchmark as the solution to an infinite horizonteamproblem. Market behavior involves herding, in the sense that agents put too little weight on their private information for any given precision of public information, and yields underinvestment in the production of public information. However, both market and optimal learning involveslowlearning. Examples of the model include learning by doing, reaching consensus, and consumer learning about quality.Journal of Economic LiteratureClassification Numbers: D82, D83.  相似文献

We study the perfect type-contingently public ex-post equilibrium (PTXE) of repeated games where players observe imperfect public signals of the actions played, and both the payoff functions and the map from actions to signal distributions depend on an unknown state. The PTXE payoffs when players are patient are determined by the solutions to a family of linear programming problems. Using this characterization, we develop conditions under which play can be as if the players have learned the state. We provide a sufficient condition for the folk theorem, and a characterization of the PTXE payoffs in games with a known monitoring structure.  相似文献

利用287名有失败经历的新创企业创业者和创业团队成员的调研数据,借助统计分析工具,实证研究了新创企业的两类失败学习模式(探索模式和利用模式)对企业成长的影响,以及失败学习内容在其中的中介作用。研究结果表明:失败学习模式中的探索模式和利用模式都对新创企业成长产生正向影响;探索模式对失败学习内容及其各维度均有正向影响,而利用模式只对失败学习内容中的自我学习、商业学习和企业管理学习3个维度有正向影响;失败学习内容在利用模式与企业成长间起完全中介作用,在探索模式与企业成长关系间起部分中介作用。  相似文献

从经历中学习是组织学习的重要方面。从科学、严谨的研究范式出发,结合东方传统的阴阳哲学思想,基于时间维度提出了包含学习主体、经历样本、成功失败经历集、学习主体特征、知和行等要素的组织从过去经历中学习的模型,并对相关问题进行了探究。具体包括:学习主体从经历中学习的认知特性;不同类型经历对应的不同学习方法,成功经历和失败经历对学习效果的差异性影响,经历集影响知和行的7种自动的和有意的学习方式;知与行相互转化及其触发机制;客观世界从时间和空间两个维度客观展开的观点等。该系统模型为未来研究提供了理论框架和实证检验方向。  相似文献

This paper describes the results of simulation experiments performed on a suite of learning algorithms. We focus on games in network contexts. These are contexts in which (1) agents have very limited information about the game and (2) play can be extremely asynchronous. There are many proposed learning algorithms in the literature. We choose a small sampling of such algorithms and use numerical simulation to explore the nature of asymptotic play. In particular, we explore the extent to which the asymptotic play depends on three factors: limited information, asynchronous play, and the degree of responsiveness of the learning algorithm.

Employment protection legislation (EPL) is not enforced uniformly across the board. There are a number of exemptions to the coverage of these provisions: firms below a given threshold scale and workers with temporary contracts are not subject to the most restrictive provisions. This within-country variation in enforcement allows us to make inferences on the impact of EPL which go beyond the usual cross-country approach. In this paper we develop a simple model which explains why these exemptions are in place to start with. Then we empirically assess the effects of EPL on dismissal probabilities and on the equilibrium size distribution of firms. Our results are in line with the predictions of the theoretical model. Workers under permanent contracts in firms with less restrictive EPL are more likely to be dismissed. However, there is no effect of the exemption threshold on the growth of firms.  相似文献

This paper examines public debt management during episodes of fiscal stabilization when long–term interest rates are generally higher than governments' expectations of future rates. We find that governments increase the share of fixed–rate long–term debt denominated in the domestic currency, the higher is the conditional volatility of short–term interest rates, the lower are long–term interest rates, and the stronger is the fall in long–term rates that follows the announcement of the stabilization program. This evidence suggests that governments tend to prefer long to short maturity debt because they are concerned about refinancing risk. However, when long–term rates are high relative to their expectations, they issue short maturity debt to minimize borrowing costs.
