US Families 2025: In search of future families

Parenting defines and cultivates gender roles for men and women, from both biological and cultural angles. From scanning the latest trends, issues, and social pulses on parenting, families and the gender roles encapsulated, it is evident that changes are taking place: dual-income families, a health insurance crisis, family-work conflicts, bioengineering, same-sex marriage, and increasing health concerns — just some of the issues — are changing in the US, while families and gender roles are being shaped and reshaped in the process. In this article, four alternative future scenarios generate implications that challenge mainstream assumptions about the future of parenting and reveal possibilities for future male and female roles. Four scenarios (Mr. & Mrs. Right Now, Marriage Marketplace, The New Waltons for the 21st Century, and Desperate Housewives) emerged from an informal workshop held at the University of Houston, Clear Lake (UHCL) February 19, 2005.     

tay's as good as cay: Reply

In a recent comment on our published work [Lettau, M., Ludvigson, S., 2001. Consumption, aggregate wealth, and expected stock returns. Journal of Finance 56, 815–850], Michael Brennan and Yihong Xia [2005. tay's as good as cay. Finance Research Letters 2, 1–14] advance the following argument: A “mechanistic” variable tay, where t is a linear time trend, forecasts stock returns. Since “t has no foresight,” the argument goes, the predictive power of this variable must be attributable to what they call “look-ahead bias.” The authors assert that cay is subject to the same look-ahead bias (generated because we use the full sample to estimate the cointegrating parameters in cay), implying that its forecasting power must be spurious. In this response, we explain why this critique is misplaced.     

Crashing into the future

The title of this paper, Crashing into the Future, references a conception of technology as containing its own future demise. It is a conception of the future as accident or discontinuous. We find this in J.G. Ballard's novel Crash (1973), in many of David Cronenberg's early films of the seventies, and more recently in his film adaptation of Crash (1996). This paper focuses on Crash (both the novel and the film) in terms of the way the future is pathologized through the car, and, in particular, how the car crash foregrounds temporality in a manner that is traumatic.     

Alternative futures: AmI scenarios and Minority Report

In the last few decades, scenarios have provided a way of analysing the implications of alternative futures, especially as they might be impacted by new technologies. This has been no less true of ambient intelligence (AmI), which may be embedded everywhere in the not so distant future. Most of the scenarios developed by AmI enthusiasts have been rather ‘sunny’, showing how the new technologies promise to make our lives more efficient, enjoyable, productive, enriching. A European project, called Safeguards in a World of Ambient Intelligence (SWAMI), deliberately developed ‘dark scenarios’ to highlight the threats to privacy, identity, trust, security and inclusiveness posed by the new technologies. The SWAMI consortium also developed a methodological structure for deconstructing and analysing the dark scenarios. This paper takes that approach a step further by applying it to a cultural artefact, partly to test the validity, utility, applicability of the SWAMI methodology to a scenario not constructed by the consortium and partly to show how some cultural artefacts can be regarded as scenarios in their own right as well as warnings about future technologies. The cultural artefact chosen here was the Steven Spielberg film Minority Report, because it features so many AmI technologies and draws attention to the issues that have been the focus of the SWAMI project.     

Bug planet: Frontier myth in Starship Troopers

This paper examines Paul Verhoeven's 1997 film Starship Troopers against Robert A. Heinlein's eponymous 1959 novel, arguing that both productions reinscribe the ideologies of America's mythic frontier history in their fictional futures. The paper shows that despite the conspicuous postmodernisation of narrative in Verhoeven's adaptation, components of the frontier mythology codified in Heinlein's novel— expansionism, Social Darwinism and a violent relationship with the indigenous Other—remain at the film's thematic centre.     

Corporate governance in South Korea: the chaebol experience

Utilizing a large sample of South Korean firms, this paper explores the impact of corporate governance in an emerging market country dominated by a few large business groups. Firms affiliated with the top five groups (chaebol) exhibit significantly lower performance and significantly higher sales growth relative to other firms. Furthermore, top executive turnover is unrelated to performance for top chaebol firms, indicating a breakdown of internal corporate governance for the largest business groups. Internal corporate governance appears much more effective for firms unrelated to the top chaebol as managers at poorly performing firms are significantly more likely to lose their job. These results imply that the lack of properly functioning internal corporate governance among the top chaebol, which dominate the Korean economy, may have increased the severity of the recent financial crisis.     

Ex ante performance from ex post models of global equity market correlations

Analysis of ex post returns reveals the time series properties of correlations, but ex ante correlations are required for efficient diversification. We find that a time-varying parameter model offers the best fit to ex post global equity market correlations, suggesting changing mean correlations and changing rates of adjustment back to the means. Nevertheless, we do not find improved forecast performance from time-varying parameter models in holdout periods. The added complexity of time-varying models does not translate into lower forecast errors.     

Alternative constructions of Tobin's q: An empirical comparison

Although Tobin's q is an attractive theoretical firm performance measure, its empirical construction is subject to considerable measurement error. In this paper we compare five estimators of q that range from a simple-to-construct estimator based on book-values to a relatively complex estimator based upon the methodology developed by Lindenberg and Ross (1981). We present comparisons of the means, medians and variances of the q estimates, and examine how robust sorting and regression results are to changes in the construction of q. We find that empirical results are sensitive to the method used to estimate Tobin's q. The simple-to-construct estimator produces empirical results that differ significantly from the alternative estimators. Among the other four estimators, one developed by Hall (1990) produces means that are higher and variances that are larger than the three alternative estimators, but does approximate those estimators in most of the empirical comparisons. Those three alternative q ratio estimators, furthermore, produce empirical results that are robust.
