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.     

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.     

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。     

CAN SECRET INTERVENTION BE COMPATIBLE WITH A NON‐PROFITMAKING CENTRAL BANK AND A FUNDAMENTAL‐CONSISTENT TARGET?

The coexistence of secret intervention operations and “the signaling channel” (Mussa. The Role of Official Intervention, 1981) seems confusing. Vitale ( Journal of International Economics, 49, 1999, 245–267) resolves this puzzle by employing an asymmetric information framework and an assumption of a fundamental‐inconsistent target for the exchange rate. Ferré and Manzano ( International Journal of Finance and Economics, 14, 2009, 378–393) follow Vitale's microstructure framework and argue that the central banks' profitability motivation offers a rationale for their secret intervention even under a target consistent with the fundamentals. However, that the authority uses its superior information to obtain speculative profits through secret intervention in the market is not a typical goal for central banks. To theoretically explain the opaqueness in non‐profitmaking central banks' exchange rate policies, we employ a model of a central bank's optimization by considering that no bank really knows the exact fundamental rate and they take into account the possible bad consequences of announcing the intervention. We also show that, in passing the bank's private information to market participants, a bank's announcement of the intervention size is equivalent to revealing its target rate. (JEL E58, F39)     

Perception of Women Managers in Singapore: A Media Analysis

The paper exmaines the factors that facilitate and inhibit women's entry into managerial positions, drawing on the findings from a previous study conducted in 1993 and comparing the results against those based on an analysis of selected contributions (from 1993–2003) in the media. A content analysis is conducted in three local newspapers on how they described woman and male managers. Profile, word and theme analysis are carried out on the selected contributions. Findings reveal that successful women managers are increasingly accepted and recognized by the society. Nonetheless, they still have to fulfill their traditional social roles. Only the talented women can make it. Implications of the findings are discussed..
