An international comparison of working times

Although national statistics on working life are difficult to compare, presented here is an overview of the trends observed in the principal industrialized countries. Pointing out first that the reduction in working time which has occurred over the past few decades, while common to all countries, has come about in different ways and at different rates, and has reached fairly unequal levels, the article emphasizes that the dominant trend today is towards the growing diversification of working time by sector, by company, and even by individual worker. This phenomenon of the individualization of working hours, doubtless attributable to new production constraints, clearly results from the more general diversification of types of work, itself concurrent with the atomization of lifestyles.     

Diversification effect of standard and optimized carry trades

Standard carry trades, which consist of purchasing high- and selling low-yield currencies, provide an economic diversification effect. However, the diversification effect is not robust, and is not borne out by much statistical evidence. We introduce optimized carry trades, which incorporate risk components such as currency volatility or currency skewness in the selection process. These optimized carry trades provide a robust economic diversification effect observed by a larger Sharpe ratio, a reduced portfolio volatility, a smaller drawdown, or a reduced tail risk with respect to a benchmark portfolio. Moreover, a significant improvement of the mean-efficient frontier is observable, with the result that minimum-variance and tangency portfolio are enhanced. The empirical results reveal that optimized carry trades have a larger diversification effect than standard carry trades and their modifications.     

Private Equity and the COVID‐19 Economic Downturn: Opportunity for Expansion?

The coronavirus‐related global economic downturn poses a significant risk to PE portfolio companies, but also represents a significant opportunity to purchase quality companies at a discount. Because the industry is today much larger, as well as more diversified and experienced, than at the time of the 2008 downturn, it is better positioned not only to weather the severe economic storm, but emerge with an even larger and stronger asset base. Compared with PE at the time of the global financial crisis, today's $3.9 trillion private equity industry has considerably more dry powder, with more heavily capitalized strategies, including private credit and “secondaries,” more permanent capital, and stronger operational capabilities. In contrast with the pre‐crisis hyper‐competitive market environment in which purchase multiples were at record highs and returns faced significant downward pressure, the fear and uncertainty that characterize current market conditions have put PE in a position to grow its asset base at bargain prices. The advantages of scale, diversification, adaptability, and access to longer‐term capital are all expected to help today's larger alternative asset groups, which have in recent years achieved greater diversification in terms of strategy as well as geography and investors.     

Planning for tourism: Research needs in a growth industry

Will tourism become the world's largest single industry by the year 2000? Although business travel is determined mainly by the economic climate, the volume of pleasure travel is influenced by a range of factors: to clarify and quantify their effects, further research is necessary. Despite the current low level of tourism promotion, most people regard holidays as necessary. As working hours decrease, tourism will increase. Energy shortages will probably result in ‘organised’ rather than individual tourism. The redistribution of tourist flows from traditional destinations to the less developed countries is likely to occur. Government involvement may increase, particularly if the social role of tourism is recognised.     

Diversification Issues in Real Estate Investment

Real estate asset management has been and will continue to be a topic of great interest. Specifically, does real estate warrant inclusion in an efficient portfolio? And if so, how much should be invested in real estate? This article reviews the extant literature in the area of real estate diversification and helps identify the reasons that there exists so much divergence in the answer to the question, “How much in real estate?” Moreover, diversification as it relates to real estate is discussed in reference to both mixed-asset portfolios and for diversification within the real estate asset class. Directions for future research are also discussed.     

The economic effects of reducing and reorganizing working time

This article goes beyond the often ideological debate for and against a reduction in working time and analyses the effects of shorter working time at company and country levels. Logic and experience dictate that such reductions must be accompanied by a process of work reorganization and include financial compensation for those working shorter hours. However, while these three ingredients are indissoluble, not all firms can proceed at the same pace and in the same ways. Nevertheless, the article shows that, as long as implementation proceeds in a decentralized and selective manner and is accompanied by a judicious reorganization of these hours, it could be extremely beneficial to all parties—companies, the state and individuals, both workers and producers.     

Demography as a forecasting tool

The European population is rapidly ageing. This implies changing economic and social relations between the generations. In turn this precipitates economic change. In particular the welfare bill in the future needs to be paid for more dependants by a smaller working population. This fundamental shift also changes the conditions for productivity growth, trade and even monetary policy. Using demographic projections to forecast these changes and integrate them into futures scenarios contributes to realism in the futures envisioned. Demographic processes can be influenced by policy, but the feedback is slow. This ensures the usefulness of demographic forecasting but it also implies that policy decisions need to be taken well in advance of the problems that ageing will cause. At horizons beyond 10–20 years there are ample opportunity to adapt the society to avoid unacceptable scenarios. Before that the scope for action is much less and much more constrained. The inertia of the demographic structure is such that it is hard and probably costly to turn unwanted trends caused by unbalanced age structures. For example, a likely consequence of the developing scarcity of labour in Europe is that the demand for education goes down in spite of the desirability for society to expand higher education.     

Sustainability and the reconstruction of academic finance

It is now widely acknowledged that tackling the ongoing global economic, social and ecological crisis will require to redefine simultaneously the existing criteria for the allocation of capital, the modalities of corporate governance, and the mission of organizations. The present special issue hence attempts to discuss new practices, remove existing epistemological obstacles to a paradigmatic diversification in finance, and carve out innovative paths for financial research.     

Demographic Transitions and Economic Miracles in Emerging Asia

The demographic transition—a change from high to low ratesof mortality and fertility—has been more dramatic in EastAsia during the twentieth century than in any other region orhistorical period. By introducing demographic variables intoan empirical model of economic growth, this article shows thatthis transition has contributed substantially to East Asia'sso-called economic miracle. The miracle occurred in part becauseEast Asia's demographic transition resulted in its working-agepopulation growing at a much faster rate than its dependentpopulation during 1965–90, thereby expanding the per capitaproductive capacity of East Asian economies. This effect wasnot inevitable; rather, it occurred because East Asian countrieshad social, economic, and political institutions and policiesthat allowed them to realize the growth potential created bythe transition. The empirical analyses indicate that populationgrowth has a purely transitional effect on economic growth;this effect operates only when the dependent and working-agepopulations are growing at different rates. These results implythat future demographic change will tend to depress growth ratesin East Asia, while it will promote more rapid economic growthin Southeast and South Asia.     

Corporate diversification and shareholder value: a survey of recent literature

We survey the recent developments in the literature on corporate diversification. This literature is voluminous, diverse, and quite old. To make the task more manageable, we focus our attention on recent contributions to that subset of the diversification literature that is in our judgment most influential in setting the agenda for financial research. The study of diversification at the corporate level can be grouped into one of two bodies of literature: cross-sectional studies of the link between corporate diversification and firm value (i.e., the diversification discount) and longitudinal studies of patterns in corporate diversification through time. The prevailing wisdom among financial economists throughout much of the last decade has been that diversified firms sell at a discount and that the level of corporate diversification has been trending downward. However, recent research questions both these tenets and a number of studies now suggest that the diversification discount is either not due to diversification at all, or may be a result of improper measurement techniques. Furthermore, some researchers are now beginning to argue that previous attempts to assess changes in the levels of corporate diversification through time is also flawed as a result of biases built into the compustat database in combination with the use of noisy proxies for corporate diversification.
