Volume,Volatility, and New York Stock Exchange Trading Halts

Trading halts increase, rather than reduce, both volume and volatility. Volume (volatility) in the first full trading day after a trading halt is 230 percent (50 to 115 percent) higher than following “pseudohalts”: nonhalt control periods matched on time of day, duration, and absolute net-of-market returns. These results are robust over different halt types and news categories. Higher posthalt volume is observed into the third day while higher posthalt volatility decays within hours. The extent of media coverage is a partial determinant of volume and volatility following both halts and pseudohalts, but a separate halt effect remains after controlling for the media effect.     

Membership patterns in USDAW 1980–1990: survival as success?

This research note examines the pattern of union membership growth in USDAW during 1980 to 1990. The union's recruitment strategies, campaigns at local and national level, and the effect of changes in the labour market such as recent equal value judgements are examined with respect to changes in membership levels.     

Money,Asset Prices,and the Liquidity Premium

This paper examines the effect of monetary policy on the market value of the liquidity services that financial assets provide, known as the liquidity premium. The theory predicts that money supply and nominal interest rates have positive effects on the liquidity premium, but asset supply has a negative effect. The empirical analysis with U.S. data confirms the theoretical predictions. The theory also proposes that the liquidity properties of assets can cause negative nominal yields when the money holding cost is low and liquid assets are scarce. The suggestive empirical findings in Switzerland to support this theoretical result are presented.     

The interplay between cost accounting knowledge and presentation formats in cost-based decision-making

Most studies on cost-based decision-making examine the profit impact of cost reports that rely on different methods to allocate costs. In practice, firms’ cost reports often employ the same cost allocation method with subtle variations in the way that the cost data are presented. This paper examines experimentally the profit impact of a cost report’s presentation format in relation to a decision maker’s level of cost accounting knowledge. Using a customer profitability report prepared using activity-based costing and presented in either a tabular or a graphical format, participants analyze a complex pricing and resource allocation task that affects firm profitability. The results suggest a strong relation between presentation format and cost accounting knowledge. Specifically, decision makers with a low level of cost accounting knowledge attain higher profits when they use a graphical format in comparison to a tabular format. More surprisingly, graphs (versus tables) have an adverse effect on profits for users with a high level of cost knowledge. This result has broad implications: in order to facilitate the decisions of a variety of users of accounting data (e.g. managers, external investors, etc.), firms may need to adapt the presentation format of their accounting data to the level of accounting sophistication of the users.     

UNION EFFECT ON THE USE OF NON‐REGULAR LABOR IN THE REPUBLIC OF KOREA

Our paper aims at analyzing the union effect on the externalization of employment relations, focusing on how labor unions affect management's strategic use of non‐regular labor within the Korean context of industrial relations. Our study presents several interesting implications. Firstly, the unions' motivator role for managerial use of non‐regular labor is more evident than its constrainer role. Secondly, union power exerts a “U‐type” impact on the use of indirect non‐regular labor, while affecting directly employed non‐regular labor in a positive linear way. Thirdly, labor unions in large establishments are more active and influential in representing their members' interests than their counterparts in small establishments with limited financial resources. In particular, the interactive function of the union's power and union leaders' attitudinal inclinations is found to be significant in the negative direction among large establishments.     

Are Apparel Trade Restrictions Regressive?

Consumer welfare losses from apparel trade restrictions are estimated across different household income levels using Hicksian Equivalent Variations. The 1980–1992 Consumer Expenditure Survey, the 1980–1992 Consumer Price Index, and the 1990 ACCRA Cost of Living Index were used. For price differences under 45 percent, consumer welfare loss from higher apparel prices due to trade restrictions is greater as a percent of total expenditures for wealthy households than for poor households. Apparel trade restrictions, therefore, have a progressive effect.

高息委托贷款与企业创新

本文分析了参与以高息委托贷款为代表的影子银行业务对企业创新活动和未来业绩的影响。通过结合管理层的短视理论,本文分析了企业从事高息委托贷款后企业创新活动变化以及盈利水平和构成的变化。结果表明,当年从事高息委托贷款降低了企业未来的专利产出水平和投入水平,并伴随未来营业利润资产收益率更低和营业外利润资产收益率更高的情形。进一步的分析表明,从事高息委托贷款与否与公司整体盈利能力没有显著差异,更多表现出盈利结构上的差异,说明从事高息委托贷款的根本动机是源于管理层的短视。
