Reverse Payments and Risk of Bankruptcy Under Private Information

Abstract

In the pharmaceutical industry, a reverse payment (pay-for-delay) is a payment from an originator to a generic producer to delay her entry. In some recent cases, the US and EU antitrust authorities have banned these agreements per se, while in others they have used a rule of reason. This paper analyzes their dynamic effects and shows that a ban per se may reduce consumer surplus when the generic producer may go bankrupt and her financial situation is private information. Reverse payments are more beneficial when competition among few players is soft, the economy is in a downturn, and the period of drug usage after patent expiry is long. Results suggest that a rule of reason is more suited than a ban per se.     

Effects of state-sponsored human capital investment on the selection of training type

Since the 1990s, firms in Japan have reduced their human capital investment in the workplace to minimize costs. Moreover, in response to the increase in the number of non-regular employees and turnover rates, workers need to have greater incentive to make the self-motivated investment in themselves for their self-protection. In this study, we first estimate the effects of workers’ self-motivated investment in themselves on wage rates. Next, we explore who is likely to participate in which training type and accordingly estimate the effects of the self-motivated investment on wage rates by training type. Our estimates controlling for individual-level fixed-effects indicate that the return is significantly positive and particularly high for practical training related to workers’ current jobs, and regular workers tend to self-select these higher-returns programs, while non-regular workers are more likely to enroll in lower-returns programs, such as schooling. This trend in investment in oneself could potentially increase the wage inequality between regular and non-regular workers through the self-selection of training types. Our estimates reveal that receiving the training and education benefit raises the likelihood for workers to participate in a high-return training program regardless of whether they are non-regular or regular workers. This suggests that government benefits on self-investment change workers’ self-selection of training type and serve to promote practical trainings that lead to high returns.     

水生态系统服务供需视角下的水网乡村 适应性规划策略——以吴江张鸭荡片区为例

苏南乡村地区一直是中国乡村建设的先行区域，特殊的纵横交错的水网结构构成了一个错综复杂的系统，呈现出其他地区不具有的复杂性和生态特殊性。随着城镇的扩张，乡村的发展建设使其水网空间的平衡发展面临极大的挑战。传统单一静态的规划方法逐渐显示出无法适应经济、社会等发展要求的缺陷。苏南乡村地区以水为核心，从水生态系统服务供需关系的视角下探究水网乡村的适应性规划策略更加适应当前的乡村现状和需求。以传统水网乡村空间形态转译为基础，建立水生态系统供需服务评估体系，在评估水生态系统服务供需能力的基础上，分析供需分异模式及供需矛盾。从构建乡村水域空间生态格局、乡村水域空间功能分区规划，以及乡村水域空间多情景预判3个方面，提出苏南水网乡村的适应性规划策略，并为水网乡村的生态实践提出新思路。     

Consumer Quality Perception in Traditional Food: Parmigiano Reggiano Cheese

Abstract

The paper aims to classify the quality cues and attributes of grated Parmigiano Reggiano cheese, an Italian traditional food cheese, exploring if they affect consumers’ quality perceptions and expectations. Analysis is based on a questionnaire administered in hypermarkets where grated Parmigiano Reggiano is sold. A factor analysis, using varimax rotation, and a cluster analysis, were performed, using the Stata 12 software package. The clusters used were: geographical origin and packaging (cluster 1); price, brand and quality certification (cluster 2); all sensory attributes (cluster 3); and a combination of sensory attributes with price, brand, and quality certification (cluster 4). This is the first study to examine the quality cues and attributes affecting quality perception and expectations of cheese for grated Parmigiano Reggiano from a consumer perspective. It is also the first to classify cheese attributes following a quality approach, encompassing previously studied sensory and other attributes.     

Economic policy uncertainty and mergers and acquisitions: Evidence from China

This study examines the relationship between economic policy uncertainty and mergers and acquisitions (M&As) in China. Using all listed Chinese companies on the Shanghai and Shenzhen Stock Exchanges as well as 4188 ​M&A deals from the period of 2001–2018, we show that Chinese firms are more likely to make acquisitions during periods of high economic policy uncertainty, which contradicts the behavior of US firms. We further show that state-owned enterprises (SOEs) are less likely than non-SOEs to make acquisitions during periods of high economic policy uncertainty. SOEs are less likely to use only cash for their acquisitions during periods of high economic policy uncertainty. These results indicate the prudence of SOEs regarding acquisitions relative to non-SOEs during periods of high economic policy uncertainty. Moreover, acquisitions during periods of high economic policy uncertainty are associated with an increase in shareholder wealth for acquirers, and this wealth effect is more pronounced for SOEs.     

Working with monsters: counting the costs of workplace psychopaths and other toxic employees

We explore the role of ‘Workplace Monsters’ in the global burden of disease, including the $US1.15 trillion annual cost of depressive and anxiety disorders. We propose the productivity drain created by these individuals is a wicked problem, integrating several disciplines to position workplace monsters as significant corporate governance issues for organisations. Our discussion covers Monster prevalence, impacts on fellow workers and estimates of the costs incurred to business. We classify Monsters as ‘appreciating liabilities’ and call for future research to develop means of accounting for their inherent organisational costs in an effort to prompt action to address their destructive impacts.     

Death spiral PIPEs: a reconsideration of the evidence

We challenge the view that PIPEs lead to unfavourable outcomes for issuing firms. We show that structured PIPEs do not have significant negative CARs when a matched firm benchmark is used for computing CARs and when sample selection bias is taken into account. Indeed, structured PIPEs have significantly higher positive skewness, indicating superior optionality, consistent with the real option argument. We also show that the 2002 intervention by the Securities and Exchange Corporation (SEC) has led to unintended consequences, with the substitution of ‘mom and pop’ investors for hedge fund investors in the structured PIPE market.     

吐温80在油脂类调味品中微生物检测的研究分析

通过对牛肉酱、红油2种即食油脂类调味品进行微生物检测,将不同比例的吐温80添加到样品前处理的稀释液中,采用浓度为107 CFU·mL-1的标准菌悬液,用常规细菌培养法检测结果。结果表明:选用比例为5%的吐温80对牛肉酱、红油的微生物指标进行检测,检测结果均在107 CFU·mL-1,与空白对照的检测结果在同一数量级上。与常规的稀释液相比,吐温80可使样品均匀分散在稀释液中,且不影响微生物的检测结果,可适用于高油脂类样品的日常微生物检测。     

食品检测实验室质量监督方法探讨

食品检测实验室中最为重要的就是质量监督管理工作,做好质量监督有利于提高实验室工作人员的质检与管理能力,进而推动有关人员的学习进步,以胜任工作岗位,提高该食品检测实验室的质量检测水平,确保检测数据的有效性与无误性。但现阶段我国的实验室由于缺乏统一的行业标准,导致其质量监督工作水平参差不齐,出现了一系列不利于质量检测的因素,比如质量监督目的不明、质量监督内容不完整、质量监督措施不完善等不足,都会影响该实验室对于食品的检测。因此,本文主要就食品检测实验室的质量监督方法进行探究,从各个方面指出质量监督的技术要点。
