A number of problems in agricultural economics involve modeling joint distributions for which the assumption of multivariate normality may not be warranted. Yet, very little work has been conducted evaluating competing methods for modeling joint dependence. We develop a simulation framework to evaluate the bias and efficiency impacts of copula choice in the context of evaluating county‐to‐farm basis risk. The results suggest significant differences in performance across various copulas and approaches. The findings have important implications for risk analysis, insurance, and policy modeling problems in agriculture regarding the selection of method to model dependence among random variables. 相似文献

Using a survey of over 4,000 firms in 21 transition economies, this paper investigates how legal extensiveness (law on the books) and legal effectiveness (law in practice) affect availability of bank finance. Our findings suggest that both law on the books and law in practice are important, but that they impact firms of different sizes differently. Small firms appear to be the most credit constrained in countries with weak creditor rights and with weak contract enforcement, while large firms are the most credit constrained in countries with weak courts and unclear and inconsistent laws pertaining to firms’ business operations. 相似文献

We analyse the optimal location choice of a monopolistic firm that operates two arbitrarily located platforms on a two‐sided market. By extending the traditional Hotelling framework, we show that the optimal platform locations are equivalent to the one‐sided benchmark if both sides are either restricted to single‐ or multi‐homing. In the mixed case (one side single‐homes, the other one multi‐homes), the optimal platform locations are in line with the respective symmetric case. If the monopolist is restricted to choosing the same location on either side of the market, the optimal locations are determined by the relative profitability of the market sides. 相似文献

采用我国30省(市、区)2003—2012年面板数据,分析环境规制强度、能源消费结构与雾霾之间的关系。首先,以PM10浓度指标进行聚类,把30省(市、区)划分为高、中、轻三大污染地区。其次,面板单位根检验结果显示各变量是一阶单整I(1);Pedroni和Kao协整检验表明变量之间存在协整关系;FMOLS回归发现,全国总体环境规制强度与PM10浓度呈反方向变动,能源消费结构与PM10浓度呈同方向变动;高污染地区能源消费结构对PM10浓度产生正的影响,中、轻污染地区环境规制强度对PM10浓度产生负的影响。最后,提出了使用法律、经济手段加强环境规制,降低煤炭消耗比例、发展清洁能源等建议。 相似文献

Distressed Canadian public firms usually file for bankruptcy protection under either the Bankruptcy and Insolvency Act (BIA) or the more flexible Companies Creditors Arrangement Act (CCAA). The latter targets reorganization while the BIA focuses on both reorganization and liquidation. This paper examines the factors that enter into the choice of either of these two regimes by bankrupt filing public firms. We document that firms are more likely to file under the CCAA when the global stock market is bullish. Larger firms, more leveraged firms and firms with higher quality bankruptcy trustees are more likely to file under CCAA. The worst performing firms also tend to file under the CCAA. Finally firms in Ontario and Quebec have a tendency to file more frequently under the BIA compared to other provinces. 相似文献

The objective of a leniency program is to reduce sanctions against collusion if a participant voluntarily confesses his behavior or cooperates with the public authority’s investigation. Constructing a model in which the detection probability varies over time, Harrington (2008) pointed out that there are three channels through which the leniency program can affect the collusion amount; furthermore, he presented a sufficient condition under which the maximum leniency is optimal. After extending the model by endogenizing the degree of collusion as well as equilibrium selection in the self-reporting stage, we revealed that the Race to the Courthouse effect disappears and that the maximum reduction is always optimal. 相似文献

To explain the persistence of dominant New York Stock Exchange (NYSE) market share in stock trading of listed securities from 1992 to 2002, we develop a dominant‐firm price leadership model and hypothesize that NYSE specialists raised the costs of rival market makers. The model predicts that natural and induced cost advantages will determine the NYSE's market share vis‐à‐vis the regional exchanges, electronic trading systems, and NASDAQ dealers. Empirically, NYSE market share increases with economies of scale and scope, abnormal price volatility, high asymmetric information, and with trading practices that raise rivals' costs, such as failure to display limit orders that bettered the existing quotes. 相似文献

In this paper, on the basis of the framework of repeated games, we consider the strategic interaction between firms that may face financial constraints and go into bankruptcy when they earn low profit. We demonstrate that under asymmetric information concerning the financial constraints of the rival firm, firms adopt a pricing pattern wherein they switch to high (or collusive) prices after maintaining low prices for some periods. There are always such predatory pricing strategies sustained as equilibria when firms are sufficiently patient. We also show that the set of feasible and individual rational payoffs becomes narrower than that of the ordinal repeated games. 相似文献

The transition economies of Central and Eastern Europe (CEE) have become important exporters of many types of services to Western Europe. We identify the sources of CEE’s advantages over competing exporters, such as India, China and Brazil, using disaggregated data on service exports and a novel estimation technique for the gravity equation. Our results indicate that the importance of geographical distance varies substantially across types of service exports. Geography is important for exports of construction services, but it has a negligible impact on computer‐related services. However, the relative quality of legal institutions influences trade across a broad range of service categories. The results demonstrate that aggregating services that are not homogeneous could conceal important differences in the effects of geographical distance and other variables on the pattern of service trade. 相似文献
