Does subsidised temporary employment get the unemployed back to work? Aneconometric analysis of two different schemes

Subsidised employment is an important tool of active labour market policies to improve the reemployment chances of the unemployed. Using unusually informative individual data from administrative records, we investigate the effects of two different schemes of subsidised temporary employment implemented in Switzerland: non-profit employment programmes (EP) and a subsidy for temporary jobs (TEMP) in private and public firms. Econometric matching methods show that TEMP is more successful than EP in getting the unemployed back to work. Compared to not participating in any programme, EP and TEMP are ineffective for unemployed who find jobs easily anyway or have a short unemployment spell. For potential and actual long-term unemployed, both programmes may have positive effects, but the effect of TEMP is larger.     

Another proof that assignment games have singleton cores only if multiple optimal matchings exist

Complementary slackness of a pair of dual linear programming problems implies the remark of Sotomayor (2003) that assignment games have singleton cores only when multiple optimal matchings exist.The author thanks Marilda Sotomayor, William Thomson, and an anonymous referee for their helpful comments.

"净利+利息+折旧"抑或"净利+税后利息+折旧"?——对会计资格考试辅导教材中经营现金净流量计量方法的商榷

计算项目净现值(NPV)等投资决策指标时,现金流量与折现率应具有匹配关系。从两者的匹配关系看,全国会计专业技术资格考试辅导教材《财务管理》一书中的经营现金净流量(NCF)计量公式有欠妥当。因为以项目的加权平均资本成本(WACC)作为折现率时,与之相应的NCF的计量方法不应是教材中的“净利 利息 折旧”,而应该是“净利 税后利息 折旧”,或者是“息税前利润(1-所得税率) 折旧”。     

企业需求、企业能力与企业社会责任的匹配探讨——一种新的企业履行社会责任的理论分析框架

本文首先研究了企业履行社会责任的模式并提出了企业社会责任的层次模型;其次,将企业需求与个人需求在企业生态学的范畴下进行了类比,提出了企业需求层次模型,并将企业需求归纳为企业履行社会责任的动力;再次,本文运用企业生命周期原理,将企业成长状况看作是衡量企业具有一定的履行社会责任能力的体现;最后,通过将企业需求、企业能力与企业社会责任进行匹配探讨,揭示了企业履行社会责任的动力和能力原理及其可能的行为,并得出了一些有意义的结论。     

社会地位对宏观经济变量的动态影响——基于两部门搜索均衡模型的研究

本文将失业理论的搜索模型与社会地位结合起来考察社会地位的动态影响。研究发现社会地位引入效用函数等价于代表性家庭时间偏好率的降低,利用对数效用函数,得到经济系统均衡状态存在的唯一性。在均衡状态下,更强的社会地位意识意味着更高的储蓄率和资本积累,以及提供更多的社会空闲职位、更高的工资、更高的就业率、更为宽松的劳动力市场和更低的利率。     

Existence of Equilibria in Matching Models of Money: A New Technique

This paper develops a new technique for proving the existence and indeterminacy of monetary equilibria in money search models with divisible money. Our technique is substantially simpler than standard constructive proofs in the literature. This paper is based on the second half of Kamiya and Shimizu (2002). We are very grateful to the associate editor and an anonymous referee of this journal for their very detailed suggestions and comments. This research is financially supported by Grant-in-Aid for Scientific Research from JSPS and MEXT.

The Manipulability of Matching Rules via Segmentation

Our matching problems feature agents with endowments facing certain division rules. At any matching, the endowments of agents are reallocated between the matched pairs according to some given division rule, and this opens doors to an iterated matching problem and rematching, and to manipulation of some matching rules via segmentation. In this form of manipulation a coalition breaks off from the rest, matches within itself and rejoins the complementary coalition for a rematching at the new endowment profile. Under certain division rules this may benefit the coalition who breaks off without hurting the complementary coalition. Furthermore, both may benefit by first matching internally and then rejoining for a new match.     

The substitutes condition and the lattice structure of the set of stable allocations

In the many-to-one matching model with contracts, I show that there is no restriction on preferences weaker than substitutable preferences which guarantees that the set of stable allocations is a lattice. Thus, when contracts are not substitutes, removing agents from the economy may decrease the payoffs to existing agents on both sides of the market.     

Firm-specific human capital in different market conditions: Evidence from the Japanese football league

This paper examined how and the extent to which obtaining skills to meet team specific human capital is important to improve football player’s performance by comparing the top league and the second league. Based on panel data of individual players during the 2012–2016 seasons of the Japan Professional Football League (J League), we found; (1) In the top-league, changing team reduced player’s performance and their performance improved as player’s tenure of the team and also tenure of J League increased. (2) returns from acquiring team specific skills on time of play in the game increase and then decrease as years have passed. (3) benefit from moving team depends on the timing of moving, and so rookie players can benefit from moving when team tenure reach 4 years or more. (4) In the second league, neither team tenure nor experience of the professional football player does not influence player’s performance.     

Jean Tirole,Nobel Prize Winner

The Royal Swedish Academy of Sciences awarded the Nobel Prize in Economic Sciences for 2014 to Jean Tirole, Toulouse School of Economics (TSE), Toulouse, France ‘for his analysis of market power and regulation’. What commonly characterizes Jean Tirole's work is a combination of rigorous scientific analysis of markets and provision of useful scientific insights and policy guidance for regulation and competition policy in such markets. This paper focuses on two of Tirole's papers, both co-written with Jean-Charles Rochet, which probably best exemplify his policy-oriented research. It summarizes and then explains how the theory that these papers develop led to the implementation of a new policy regulating the payment card industry in the European Union.
