Who are the world's most successful companies?

It seems that everybody wants to know which companies are the most successful. To help throw light on the issue, and to do so more reliably than the plethora of league tables and charts produced by most business magazines, the London Business School have teamed up with The Economist to compile an assessment of the top performers of the 1980's.     

COMMERCIAL ART MUSIC

A commercial environment is clearly good for contemporary popular music but can ‘art’ music flourish in such an environment? In the past art music has prospered on a commercial basis and there are advantages in exposing art to commerce. For example, commercial patronage is likely to be more diverse and allow more room for experimentation than a single patron or subsidising body. Moreover, commerce encourages two‐way communication between artist and audience.     

HOW EFFECTIVE ARE STATE EMPLOYMENT AGENCIES? JOBCENTRE USE AND JOB MATCHING IN BRITAIN

Abstract State sponsored employment agencies are an important source of job matching in Britain. This study tracks Jobcentre use in Britain over the previous decade and the effectiveness of Jobcentre use in securing entry into employment for those who utilise its services. Amongst the unemployed, use of Jobcentres is highly counter-cyclical. This can be attributed principally to the changing composition of the stock over the economic cycle. In good times, there are relatively more short duration, voluntary quits in the stock, who tend to rely on Jobcentres least. Jobcentres are found to have a significant positive effect on the job entry rates of its clients. The greatest beneficial impact is amongst those, the low skilled and the long term unemployed with the lowest exit rates from unemployment.     

IMPACT OF THE MINIMUM WAGE ON THE INCIDENCE OF SECOND JOB HOLDING IN BRITAIN

The advent of any earnings boost, such as provided by the introduction of a minimum wage, might be expected to reduce the supply of low‐paid individuals wanting to hold a second job. This paper uses difference‐in‐differences estimation on a panel of individuals matched across successive Labour Force Surveys around the time of the introduction of the national minimum wage in the United Kingdom in order to estimate the impact of the minimum wage and its subsequent upratings on second job working. There is little evidence to suggest that the extra pay provided by the introduction of the minimum wage was sufficient to affect the incidence of second job holding significantly. However, hours worked in the main job by second job holders may have risen relative to those not covered by the minimum wage; and hours worked in second jobs may have fallen for those whose second job was initially below the minimum.     

Encouraging Professional Skepticism in the Industry Specialization Era

This paper provides theory and experimental evidence that, under common audit conditions, industry specialization inhibits some aspects of auditors’ professional skepticism. As auditors amass industry experience, they develop extensive knowledge of non-misstatement explanations for unusual financial statement fluctuations. This knowledge coupled with confidence in their ability to analyze audit evidence inhibits their inclination to be skeptical when there are no overt indicators of elevated misstatement risk. Although these conditions are, by definition, the conditions where misstatements are least likely, they are also the same conditions where the PCAOB has alleged pervasive insufficient professional skepticism and where well-concealed fraud is possible. These results pose an ethical dilemma for the PCAOB in terms of weighing its charge to protect the public interest against the fairness of its inspections to audit firms. Encouragingly, I also predict and find that audit firm efforts to promote professional skepticism are more effective for specialists as non-specialists are skeptical regardless of these efforts.     

Royal African Company Share Prices during the South Sea Bubble

Price bubbles provide a unique opportunity to test whether investors act rationally and have sufficient knowledge of the economic environment in which they trade. We focus our attention on the 1720 South Sea bubble episode as experienced by a company not involved in governmental debt financing—the Royal African Company. Following the example of the South Sea Company, the Royal African Company lent its funds to equityholders at a preferential rate. Recognizing this benefit along with the announced dividends explains a large portion of the bubble. Furthermore, the unexplained residual does not behave like an exploding bubble, casting doubt that speculative excess motivated market participants in 1720. Our findings are indeed consistent with investor rationality, and the unexplained residual suggests that we are missing information that was available to the British financial market in 1720.     

Central bank haircut policy

We present a model of central bank collateralized lending to study the optimal choice of the haircut policy. We show that a lending facility provides a bundle of two types of insurance: insurance against liquidity risk as well as insurance against downside risk of the collateral. Setting a haircut therefore involves balancing the trade-off between relaxing the liquidity constraints of agents on one hand, and increasing potential inflation risk and distorting the portfolio choices of agents on the other. We argue that the optimal haircut is higher when the central bank is unable to lend exclusively to agents who actually need liquidity. Finally, for a temporary surprise drop in the haircut, the central bank can be more aggressive than when setting a permanent level of the haircut.     

How universal health care would influence decisions about work and retirement

The current U.S. health care system distorts individual decisions about work and retirement. After a brief explanation of how the current health care system works, this article reviews those distortions and considers how individuals would respond to the implementation of a universal health care system. The author argues that the likely adverse impacts of an employer health insurance mandate on low-skilled workers could be more than offset by a well-designed system of government subsidies.     

Prediction of decomposition limits for ethylene oxide-nitrogen vapor mixtures

A decomposition limit equation applicable to liquid ethylene oxide storage conditions based on recently obtained data is presented. Comparison is made with a second correlation equation developed from literature data. Adjustment of predicted decomposition limits to produce recommended safe operating limits is discussed.
