Why Have Corporate Tax Revenues Declined? Another Look   总被引:1,自引:0,他引:1  
The relative constancy of non-financial corporate tax revenuesas a share of US GDP masks offsetting trends in the ratio ofcorporate profits to GDP (declining) and the average tax rate(increasing). The average tax rate rose steadily between 1996and 2003, an increase largely attributable to the importanceof tax losses. This rise casts some doubt on the role of taxplanning activities in reducing corporate taxes. So, too, doesthe relative stability of the rate of profit (relative to netassets), which might be expected to have declined had the understatementof profits for tax purposes been increasing.

The macroeconomics of the labor market: three fundamental views   总被引:2,自引:0,他引:2  
We distinguish and assess three fundamental views of the labor market regarding the movements in unemployment: (1) the frictionless equilibrium view; (2) the chain reaction theory, or prolonged adjustment view; and (3) the hysteresis view. While the frictionless view implies a clear compartmentalization between the short- and long-run, the hysteresis view implies that all the short-run fluctuations automatically turn into long-run changes in the unemployment rate. We assert the problems faced by these conceptions in explaining the diversity of labor market experiences across the OECD labor markets. We argue that the prolonged adjustment view can overcome these problems since it implies that the short, medium, and long-runs are interrelated, merging with one another along an intertemporal continuum.

Prior empirical research suggests that consumers perceive pioneers as more prototypical (i.e., representative) of their product categories than me-too followers. This prototypicality advantage is believed to contribute to an enduring marketplace advantage for the pioneer. We extend research into pioneering prototypicality advantages by considering the ramifications of simultaneous product design (i.e., product attribute) evolutions. We hypothesize that the simultaneous evolution of product designs of both the pioneer and me-too will diminish the pioneer’s prototypicality advantage over the me-too, even though the me-too does not initiate the change. To test our hypotheses, we create an experimental environment consisting of four cells, each corresponding to a different marketplace scenario: a no-change condition; a simultaneous-evolution condition; a pioneer-updates-first condition; and a leapfrogging (i.e., me-too updates first) condition. The results suggest that simultaneous design evolutions can diminish the pioneer’s prototypicality advantage. As a result, me-too entry may be a more attractive strategy in the long-run than currently believed in product categories characterized by substantial design evolution.

The Sarbanes–Oxley Act of 2002 requires audit committees of public companies’ boards of directors to install an anonymous reporting channel to assist in deterring and detecting accounting fraud and control weaknesses. While it is generally accepted that the availability of such a reporting channel may reduce the reporting cost of the observer of a questionable act, there is concern that the addition of such a channel may decrease the overall effectiveness compared to a system employing only non-anonymous reporting options. The rationale underlying this concern involves the would-be reporter’s likelihood of reporting, the seriousness with which the organization treats an anonymous report, and the organization’s ability to thoroughly follow-up the report. Thus, we explore the extent to which the availability of an anonymous reporting channel influences intended use of non-anonymous reporting channels. Further, in response to Sarbanes–Oxley and the environment of financial scandals that led to its passage, many firms are strengthening their internal audit departments, and providing them with greater independence from upper management’s direct control. Accordingly, our examination tests whether the intended use of the internal audit department as an internal reporting channel is greater when the internal audit department is of “high” versus “low” quality. Finally, the study investigates intended reporting behavior across three different cases (e.g., settings). Results show that the existence of an anonymous channel does reduce the likelihood of reporting to non-anonymous channels, that generally the internal audit department quality does not affect reporting to non-anonymous channels, and that case-setting affects the type of channel to be used. Implications from the study are discussed.  相似文献

This paper uses personnel records of employees from an Australian bank to analyse the labour market consequences of career interruptions due to voluntary military service during the Second World War. The records contain the employees’ career position and pay histories, and pre-war outcomes are used to control for selection bias caused by non-random enlistment. It is shown that, despite losing human capital during the War, upon their return veterans did not face a wage penalty relative to non-volunteers. Finally, evidence from non-wage outcomes suggests that the absence of a wage penalty was a form of positive discrimination by the Bank.

Patients decide on where to consume hospital services in Germany. Thus, the understanding of the exact hospital selection criteria and their weights is important. This research reviews the antecedents of hospital selection utilizing the conjoint methodology with regard to six questions. (1) Which are the relevant choice criteria, and (2) what are their weights? (3) Which criteria receive an increased importance in the absence of experience? (4) Do differences between compulsory and privately insured patients, (5) between hospitals with regard to their size, and (6) between female and male patients exist? The relevance and importance of nine pre-selected criteria are determined through two conjoint analyses. Experience is found to be most important followed by referral by general practitioner, certified quality management system, positive press coverage, recommendation by relatives and acquaintances and distance to the hospital. Reception area design and the personnel's friendliness, the website quality and the published quality report are less relevant. Without experience, reception area design, personnel's friendliness and distance to the hospital receive an increased importance. In addition, for some criteria notable discrepancies between female and male patients and between patients with different insurance policies are found.  相似文献

Jason Scott Smith's ambitious, some might say overly-ambitious,goal is to "construct a new narrative" of the New Deal's significanceby using the lens of political economy to examine and explainhow the policies initiated during that historical phase "revolutionizedthe priorities of the American state, radically transformingthe physical landscape, political system, and economy of theUnited States" (p. 1). Smith most certainly does not see NewDeal policies as failures that were incapable of getting theU.S.  相似文献
