Reconciling Alternative Theories for the Safety of Owner–Operators

Motor carrier safety is an important concern of shippers, carriers, policy makers, consignees, insurance providers, and the motoring public. One aspect of carrier safety that has garnered substantial attention is whether carriers making greater use of owner–operators are more or less safe vis‐à‐vis carriers making greater use of employee drivers. Currently, conflicting theoretical predictions exist regarding the direction of this relationship. In this article, we offer a reconciliation of the alternative theoretical predictions by developing a coherent theory that merges sociological rational choice theory and theory regarding motor carrier safety. We subject our theory to empirical testing by fitting a series of seemingly unrelated regression models to a vector of safety measures tracked as part of the Federal Motor Carrier Safety Administration's Compliance, Safety, and Accountability program. Our results are consistent with our proposed theory of owner—operator safety and provide meaningful theoretical and managerial implications and directions for future research.     

Trade, product cycles, and inequality within and between countries

Abstract.  This paper incorporates Northern product innovation and product‐cycle‐driven technology transfer into the continuum‐of‐goods Heckscher‐Ohlin model. The creation of very skill‐intensive goods induces the North to transfer production of older, less skill‐intensive goods to the South. These relocated goods are the most skill intensive by Southern standards. Hence, product cycles raise the relative demand for skilled workers and thus wage inequality within both regions. This runs contrary to the Stolper‐Samuelson theorem, but accords well with the fact that wage inequality has risen in both Northern and Southern countries. Moreover, product cycles increase income inequality between countries. JEL classification: F1     

有源测试与无源测试“仅”用手提检测器进行测试，不利于安装吗？

目前,评测超5类结构化布线系统的标准,都记录在2000年1月发行的TIA/EIA(电信工业协会/电子工业联合会)568A-5当中。6类系统的标准应在一年左右得到认可。 近来,各公司都开始提出,要想真正得到一个确保网络最大效率的结构化布线系统,唯一的方法就是选择那些在有源信道中经过独立测试的产品,     

The Long-run Effects of the Italian Pension Reforms

The paper analysesthe reforms of the Italian mandatory pension scheme for employeeslegislated in the 1990s. To assess the effects of the reforms,a microsimulation model calibrated on cross-section data is developed.The model is aimed at estimating the average income of a memberof a cohort, as well as the average per capita income of allindividuals alive in a given year. The long-run effects of thereform are analysed, comparing the characteristics of alternativefinancing schemes. A substantial improvement of the equity aswell as the long-run sustainability of the Italian public pensionschemes emerges. However, the dreary demographic scenario callsfor further tightening of eligibility rules sometime in the nextdecades if long-run sustainability of public debt is to be achieved.On the basis of sensitivity analysis, some changes aimed at hedgingthe system against unexpected shocks are suggested.     

The Prophecy of Place: A Labor Market Study of Young Women and Education

This study demonstrates that place—defined in this article as labor market area (LMA)— provides a useful context for examining how youth manage gendered situations. Places vary by conditions in which gender is more, less or differently salient, and a particular mix of factors accommodates different individual outcomes. This study utilizes multi–level modeling to examine influence of LMA characteristics on over–time educational measures for young women (Center for Human Resource Research 1994). Hierarchical models determine place–level effects on both average outcomes (within and between LMAs) and attainment processes. A major finding of this study is that aggregate place effects channel personal decisions and outcomes of young women. Young women's educational aspirations are dependent on gender– specific variables such as the number of women in college or the number of young women married in a local area. Attainment depends on the percentage of women in higher education and a local labor market's average age at first marriage. Further, what are assumed to be positive environmental effects (e.g., manufacturing dominance) are based on structural advantages for men and actually depress outcomes for women. Notably, the influence of place is independent of strong individual–level determinants, including social class.     

Reporting Performance: Comprehensive Income and its Components

The underlying question raised in this article is: why is the accounting profession's conceptual framework (CF) so authoritative when it is conceptually incoherent? A supplementary question is how can ‘conceptually robust’ accounting standards be derived from an incoherent framework? This article draws on Page and Spira's (1999) contrasting framework metaphors to suggest that the appearance of conceptual robustness is more important than the reality, and illustrates the point with the International Accounting Standards Board's (IASB’s) progress report on its reporting performance project. Some inherent weaknesses in the move towards internationally enforceable financial regulations have been acknowledged, but this article suggests the IASB's project demonstrates two additional weaknesses: internal incoherence, and the potential for political ends to drive supposedly technical regulations.     

The persistence of knowledge‐based advantage: an empirical test for product performance and technological knowledge

Resource‐based theory maintains that intrinsic characteristics of resources and capabilities, such as their tacitness, complexity, and specificity, prevent imitation and thereby prolong exceptional performance. There is little direct evidence to verify these claims, yet a substantial literature encourages firms to formulate competitive strategies around resources with these attributes. Further, work outside the resource‐based tradition suggests that these attributes can slow innovation, and it is not clear when this effect outweighs the benefits of inimitability. This paper seeks to clarify whether and how the complexity, tacitness, and specificity of a firm's knowledge affect the persistence of its performance advantages. We find that the complexity and tacitness of technological knowledge are useful for defending a firm's major product improvements from imitation, but not for protecting its minor improvements. The design specificity of technological knowledge delayed imitation of minor improvements in this study. Copyright © 2002 John Wiley & Sons, Ltd.     

Auditing in the Presence of Outside Sources of Information

We examine how an auditor's ability to terminate a multi-period client relationship provides the auditor with a real option whose value depends on the nature of informational asymmetry between the incumbent and other potential auditors. In particular, we isolate conditions under which the auditor's private and public sources of information behave as complements rather than substitutes. In such circumstances, increasing the likelihood of publicly provided information induces the auditor to expend more (rather than less)resources in private information gathering activities.     

Regulatory reform of the UK gas market: The sase of the storage auction

The UK gas industry has undergone major changes since it was privatised in 1986 as a fully integrated monopoly. The most significant of these has occurred not as a result of the privatisation legislation but by the intervention of the ordinary competition authorities in support of an active industry regulator. While price capping continues to be used as the primary instrument for welfare protection against the still substantial monopolistic powers of the incumbent, new competition (which has been positively encouraged) has had the greater impact on prices and choice. Recently, however, the regulator has encouraged the use of auctions for the sale of storage capacity. This paper considers the merits of auctions and makes a tentative evaluation of their effectiveness. Further use of auctions is recommended but reserve prices are considered inappropriate where monopoly power still remains.     

The determinants of bilateral trade

Abstract.  In this paper we present a monopolistic competition model that incorporates asymmetric trade barriers and international differences in production costs. The model implies a highly non‐linear bilateral trade equation. Estimation of this equation yields parameters for the elasticity of substitution and trade costs that are more reasonable than those found in previous studies. A simulation indicates that trade liberalization will shift trade from rich countries to poor countries and from within continental trading partners with preferential trade agreements to intercontinental trading partners.
