Firm-level interactions between exporting and productivity: Industry-specific evidence

This paper investigates interactions between exporting and productivity at the firm level, using a panel of firms in the UK chemical industry. This is both highly technology intensive and the UK’s largest exporting sector. We find exporters are more productive than non-exporters, but are also on average smaller. This superior productivity performance among exporters appears to be caused by both self-selection and learning-by-exporting effects. In contrast to other studies, we find learning effects are significantly positive among new entrants, weaker for more experienced exporters and negative for established exporters. JEL no.

Short-term safety or long-term failure? Empirical evidence of the impact of securitization on bank risk

Based on a sample of U.S. commercial banks from 2002 to 2012, this paper shows that bank loan securitization has a significant and positive impact on both Z-scores and the likelihood of bank failure, indicating a short-term risk reduction and a long-term risk increase effect. We also find disparate impacts between mortgage and non-mortgage securitization. Loan sale activities are found to have a similar impact to securitization.     

Alan Gillie,Input-Output Economics.

Turnovsky observes that “the rational expectations hypothesis has had a profound impact on macroeconomic theory and policy during the past decade.” Tracing briefly the evolution of the ideas involved, he concludes that “… a consensus view is emerging that in fact under quite plausible conditions the policy neutrality proposition does not hold; therefore, there is still scope for policy rules to play an important role in stabilizing output.”

The mathematics used in the article is expository rather than analytical, requiring of the reader only somewhat more than the usual amount of persistence, faith in the author's interpretation of the literature, and a willingness to accept the integrity of economic models as representative of the real world. This is “required” reading for those teaching macroeconomics.     

产业转移中的企业自我选择效应分析——基于区域产业结构理论的演变

对区域产业结构演变的三个层面进行理论分析,将研究视角从传统理论的模式化、新经济地理理论的抽象化转向异质性企业选择的微观化,进而探索影响区域产业转移的微观动力机制,即企业的自我选择效应、集聚效应与扩散效应同时成为影响区域产业结构演变的三种内在力量。结果表明:从企业微观层面看,集聚效应在一定时期内还得继续存在;政府应加大基础设施建设方面的投入,并在产业链整合、市场化等方面给予一定的政策支持以实现产业结构的跨区域整合。     

Symmetric Positive Equilibrium Problem: A Framework for Rationalizing Economic Behavior with Limited Information

The PMP methodology is extended to deal with many economic units, self-selection arising from heterogeneous economic behavior, and multiple limiting inputs. The novel structure for the analysis of this type of problems acquires the name "symmetric positive equilibrium problem." This methodology is articulated in three phases that parallel those one of positive mathematical programming. The recovery of a cost function that calibrates the base-year decisions of each economic unit is realized within a maximum entropy framework. The methodology is illustrated by the analysis of a sample of Italian farms that operate under the complex policy mandates of the European Union.     

Self-Selection and Optimal Nonlinear Effluent Charges

This paper proposes an optimal nonlinear effluent-charge system forenvironmental pollution control. This system achieves the first-bestoptimum through a self-selecting mechanism under asymmetric information.The proposed system can also control the level of revenues so as to reducethe excess burden of environmental taxation, and discriminate among thepolluters. The paper also compares this system with the conventional lineareffluent-charge system and discusses some economic implications ofimplementing the system.     

Introducing Empirical Exercises into Principles of Economics

McGrath and Tiemann discuss the rationale for requiring students to become familiar with the empirical side of economics and describe seven exercises that can be used in the first course.     

The Role of Collateral in Entrepreneurial Finance

Abstract:  Previous research has suggested collateral has the role of sorting entrepreneurs either by observed risk or by private information. In order to test these roles, this paper develops a model which incorporates a signalling process (sorting by observed risk) into the design of an incentive-compatible menu of loan contracts which works as a self-selection mechanism (sorting by private information). It then tests this Sorting by Signalling and Self-Selection Model, using the 1998 US Survey of Small Business Finances. It reports for the first time that: high type entrepreneurs are more likely to pledge collateral and pay a lower interest rate; and entrepreneurs who transfer good signals enjoy better contracts than those transferring bad signals. These findings suggest that the Sorting by Signalling and Self-Selection Model sheds more light on entrepreneurial debt finance than either the sorting-by-observed-risk or the sorting-by-private information paradigms on their own.     

异质性企业出口行为的实证研究——基于中国企业面板数据

在近年兴起的新—新贸易理论中,出口行为与企业生产率之间的双向因果关系的实证研究逐渐成为主要的热点领域。许多学者用不同国家企业数据验证了自我选择效应和出口学习效应两个逻辑相反的假设。我们利用中国企业的微观层面数据对该命题进行验证。结果表明,自我选择效应显著,而出口学习效应不显著。最后在分析中国企业国际化行为特征的基础上,给出政策建议。     

The effect of self-selection bias on the testing of a stock price reaction to management's earnings forecasts

This study examines the inferential bias due to the failure to control for self-selection when studying the market's reaction to management earnings forecasts. The analysis is conducted by controlling for self-selection and comparing the results to those obtained when self-selection is not controlled. This comparison suggests that the overall inference of a market reaction to the management forecast issuance does not change. However, the statistical significance declines when self-selection is considered. Since the issuance of a management forecast is an obvious self-selection, the results of this study suggest that self-selection should be considered and evaluated in quasi-experimental studies in accounting and finance.
