A semiparametric cointegrating regression: Investigating the effects of age distributions on consumption and saving

We consider a semiparametric cointegrating regression model, for which the disequilibrium error is further explained nonparametrically by a functional of distributions changing over time. The paper develops the statistical theories of the model. We propose an efficient econometric estimator and obtain its asymptotic distribution. A specification test for the model is also investigated. The model and methodology are applied to analyze how an aging population in the US influences the consumption level and the savings rate. We find that the impact of age distribution on the consumption level and the savings rate is consistent with the life-cycle hypothesis.     

Signal Jamming in Pretrial Negotiation with Multiple Defendants

This article analyzes the pretrial settlement process among an uninformed plaintiff and multiple defendants who share information about the winning chances of their cases. We show that when the chances are negatively correlated, cross-type subsidization occurs to circumvent the possibility of signal jamming, that is, the settlement offer of a strong defendant (a weak defendant) is distorted upward (downward), as far as the no-distortion equilibrium is not viable. In this equilibrium, the plaintiff settles with defendants with probability one.     

Efficiency of the OLSE for regressions on two-dimensional grids with sinusoidal regressors and spatially correlated errors

For spatial regressions with sinusoidal surfaces, the ordinary least squares estimator (OLSE) is shown to be asymptotically as efficient as the generalized least squares estimator (GLSE) in that the covariance matrices of the two estimators have the same nontrivial limit under the same normalization.     

Nonstationary nonlinear heteroskedasticity in regression

This paper considers the regression with errors having nonstationary nonlinear heteroskedasticity. For both the usual stationary regression and the nonstationary cointegrating regression, we develop the asymptotic theories for the least squares methods in the presence of conditional heterogeneity given as a nonlinear function of an integrated process. In particular, we show that the nonstationarity of volatility in the regression errors may induce spuriousness of the underlying regression, if excessive nonstationary volatility is present in the errors. Mild nonstationary volatilities do not render the underlying regression spurious, but their presence makes the least squares estimator asymptotically biased and inefficient and the usual chi-square test invalid.

A regression model of the heteroscedastic error variance

We introduce a regression model of the heteroscedastic error variance. A repetitive use of the least squares method is shown to provide the best linear unbiased estimator of the parameter vector of the model.

Understanding the human side of openness: the fit between open innovation modes and CEO characteristics

In small- and medium-sized enterprises (SMEs), where typically the decision-making process is highly centralised, important decisions, such as open innovation (OI) adoption, will be strongly influenced by the characteristics of their Chief Executive Officers (CEOs). Pointing the attention to the strategic leadership and human elements, this paper sheds light on the micro-foundation of OI by emphasising the role that the personal traits of key individuals in innovation. OI adoption could result in the enactment of several OI modes – each representing an opportunity of potential change (of market, of technology or/and of the organisation) – and this paper attempts to examine the relationships between the CEO characteristics and each of the OI modes. Our analysis, using Korean SME data, shows that CEOs’ positive attitude, entrepreneurial orientation (EO), patience and education can play important roles in facilitating OI in SMEs. However, this paper also observed that the effects of CEO characteristics on OI adoption were differently configured according to the nature of each OI mode, for example, CEOs’ patience and EO had different impacts depending on the degree of uncertainty in the OI mode. This suggest that OI must be understood as a wide innovation spectrum, and, to increase opportunities for successful OI adoption, CEOs have to attempt to compensate for characteristics they may lack by recruiting appropriate complementary top managements. The research has practical implications for CEOs and policy makers who are interested in enhancing competitiveness of SMEs.     

Interdisciplinarity in design education: understanding the undergraduate student experience

Interdisciplinarity is becoming a critical issue of concern for design schools across East Asia in their attempts to provide industry graduates with the skills and competences to make creative contributions in a global economy. As a result, East Asian higher education institutions are aggressively endeavouring to provide interdisciplinary undergraduate curriculum that combine traditional designerly skills with engineering knowledge and methods. The current study takes an interdisciplinary undergraduate course as case-study to examine how the pedagogic strategy of team teaching influences student learning experience. Two surveys of student learning were conducted for this research purpose. The first provided an indication of the holistic student learning experience, while the second explored the conditions of team and non-team teaching as influence upon learning experiences specifically. Results showed how students taught by a single instructor provided a more positive overall opinion of course quality and experienced significantly more encouragement to participate compared to team taught respondents. However, findings also indicated how team teaching significantly increased the students’ experience of a balanced contribution from different disciplinary perspectives and how the team teaching approach was significantly more effective in providing students with greater opportunities to understand the relevance of the different disciplines to the course subject. We conclude with a discussion of results in terms of the effective use of team teaching at undergraduate level as strategy for interdisciplinary learning experiences.
