The worldwide monetary tightening, which was necessary to contain the inflationary effects of last year's cyclical upturn, is close to having run its course. The boom is giving way to a period of slower but more sustainable growth, while the distribution and structure of demand has turned out to be more favourable than could have been anticipated. The US economy has successfully slowed (but recession seems unlikely), whilst Japan and Europe are still expanding rapidly. The world economy thus continues to grow at a rate of around 2.75 per cent, allowing modest reductions in international current account imbalances. The impact of interest rates has been felt mainly by consumers and in the housing market, and has had only a limited effect on investment and trade. So demand has been reduced but not at the expense of a capacity expansion which will, through productivity gains, dampen inflationary pressures. We expect world inflation to fall slowly front a little above 4 per cent currently to around 3 per cent by 1992. This is above the declared objectives of policy makers but is as close to the hoped-for soft landing as may be achievable.     

On the efficiency of the UK rubber market

This paper seeks to establish whether the efficient markets theory can be applied to the London Rubber Market by analysing the price changes observed in that market for daily cash and future price series during the periods January 1975 to June 1983, and January 1980 to May 1983 respectively. The analysis features an examination of the return distributions and parametric, non-parametric, and economic tests based on auto-correlation coefficients, runs, and filter tests. The results support the hypothesis of weak-form efficiency.     

Shifting responsibility to workers: the future of retirement adequacy in the United States

While many 401(k) participants at large companies can expect replacement of nearly 100% of preretirement income, not all workers participate in their 401(k) plan. Moreover, the authors show that even among participants, the extent of retirement preparedness depends on defined benefit (DB) plan coverage and retiree medical benefit generosity. Given recent trends in the elimination of DB plans and retiree medical subsidies and the voluntary nature of 401(k) participation, retirement income responsibility is increasingly shifting to workers. The authors discuss how employers might help workers meet their retirement income needs in this changing environment.     

The impact of financing decisions on the security returns of real estate corporations

This research investigates the valuation impact of financing decisions on the common stock of real estate corporations. We compare the results of our study with the results of similar studies in the corporate finance literature to test whether the response to security offerings by real estate firms differs systematically from the response to offerings by industrial and utility firms. The results of this study indicate a generally favorable price response to straight bond announcements, and unfavorable responses to common stock, convertible bonds, and lines of credit announcements.     

An examination of the role of security clauses and deposits in residential lease contracts

This paper argues that security clauses in lease contracts create a contingent claim on the value of the leased property, which resembles a put option on common stock. Adapting the standard results from option pricing theory gives insight into how landlords determine security deposit amounts, which serve to guarantee performance of the contract. Empirical tests show that deposit amounts are affected by the propensity of a property to be damaged, the propensity of a tenant to cause damage, and other characteristics of the landlord-tenant relationship. Two-stage least squares and probit regression estimates, however, provide only limited evidence to suggest that advance deposits significantly reduce tenant damages in the residential rental market.     

The characteristics of technically orientated firms: Evidence from the unlisted securities market

The results of a survey of the research, design and development activity of firms listed on the UK Unlisted Securities Market are reported. The significance of different corporate objectives, types of market structure, forms of rivalry, different groups as project initiators, and techniques of project evaluation, is reported. Technically progressive firms could not be distinguished from less technically progressive firms using univariate tests. Multiple discriminant analyses indicated that technically progressive firms operate in markets where products characteristics and advertising are significant forms of rivalry, the growth rate of profits is more important as a corporate objective and the significance of interdepartmental committees as an initiating group is higher than for less technically progressive firms. The latter firms judged price competition and the objective of achieving a target level of units sold as more significant than the former group.     

Growth outside the core

Growth in an adjacent market is tougher than it looks; three-quarters of the time, the effort fails. But companies can change those odds dramatically. Results from a five-year study of corporate growth conducted by Bain & Company reveal that adjacency expansion succeeds only when built around strong core businesses that have the potential to become market leaders. And the best place to look for adjacency opportunities is inside a company's strongest customers. The study also found that the most successful companies were able to consistently, profitably outgrow their rivals by developing a formula for pushing out the boundaries of their core businesses in predictable, repeatable ways. Companies use their repeatability formulas to expand into any number of adjacencies. Some companies make repeated geographic moves, as Vodafone has done in expanding from one geographic market to another over the past 13 years, building revenues from $1 billion in 1990 to $48 billion in 2003. Others apply a superior business model to new segments. Dell, for example, has repeatedly adapted its direct-to-customer model to new customer segments and new product categories. In other cases, companies develop hybrid approaches. Nike executed a series of different types of adjacency moves: it expanded into adjacent customer segments, introduced new products, developed new distribution channels, and then moved into adjacent geographic markets. The successful repeaters in the study had two common characteristics. First, they were extraordinarily disciplined, applying rigorous screens before they made an adjacency move. This discipline paid off in the form of learning curve benefits, increased speed, and lower complexity. And second, in almost all cases, they developed their repeatable formulas by studying their customers and their customers' economics very, very carefully.
