A SIGNALING THEORY OF GRADE INFLATION*

When employers cannot tell whether a school truly has many good students or just gives easy grades, a school has incentives to inflate grades to help its mediocre students, despite concerns about preserving the value of good grades for its good students. We construct a signaling model where grades are inflated in equilibrium. The inability to commit to an honest grading policy reduces the efficiency of job assignment and hurts a school. Grade inflation by one school makes it easier for another school to do likewise, thus providing a channel to make grade exaggeration contagious.     

PERIODICITIES OF FOREIGN EXCHANGE MARKETS AND THE DIRECTIONAL CHANGE POWER LAW

This paper utilizes advanced methods from Fourier analysis in order to describe periodicities in financial ultrahigh frequency foreign exchange data. The Lomb–Scargle Fourier transform is used to take into account the irregularity in spacing in the time domain. It provides a natural framework for the power spectra of different inhomogeneous time‐series processes to be easily and quickly estimated. Furthermore, an event‐based approach in intrinsic time based on a power‐law relationship is employed using different event thresholds to filter the foreign exchange tick‐data. The calculated spectral density demonstrates that the price process in intrinsic time contains different periodic components for directional changes, especially in the medium–long term, implying the existence of stylized facts of ultrahigh frequency data in the frequency domain.

The ad creativity cube: conceptualization and initial validation

Advertising creativity is conceptualized as a function of three dimensions—novelty, meaningfulness, and connectedness. Novelty and meaningfulness involve infocentric aspects, while connectedness incorporates the perspective of the audience. The relationship among these dimensions and ad effectiveness, and the linkage of ad creativity level to persuasion is then posited. Two experiments were conducted among 201 undergraduates. The first tested novelty and meaningfulness; while the second tested connectedness and meaningfulness. The results affirm the proposed conceptual framework. Relative to non-novel and meaningful ads, novel and meaningful ads generated higher ad recall, more favorable ad attitudes, and more upbeat feelings. Novel and non-meaningful ads elicited higher recall, more favorable attitudes toward non-claim elements (Aad-nc), and negative feelings, and less favorable ad attutides toward claim elements (Aad-c) than non-novel and non-meaningful ads. Relative to ads that did not connect with the audience, connected ads elicited higher ad recall, more favorable Aad-c under meaningful ads, lower Aad-c under non-meaningful ads, and higher levels of Aad-nc and warm feelings under both meaningful and non-meaningful ads.

A theory of reasoned action perspective of voting behavior: Model and empirical test

A model based on the theory of reasoned action was developed to analyze voting behavior. Based on an empirical test in Singapore, the proposed model was found to be generally effective in predicting the intentions of voters. Attitudes toward the candidate and political party contributed more to explaining variation in voting intention than interpersonal and mass media subjective-norm components. Direct measures of affect served to better account for voting intention variation than componentially derived measures, although they did not completely mediate the latter's effect. Implications of the findings are discussed and suggestions for future research furnished © 1995 John Wiley & Sons, Inc.     

Seasonality and the Life-cycle Permanent Income Hypothesis: Evidence for Australia, the United Kingdom and Germany

Intra-year observed consumption displays substantial seasonality. Consumers allocate their non-durable expenditure over the four quarters of the year, maximising total utility subject to the period-to-period budget constraint. Osborn (1988) derives a seasonally-varying utility function, for which Hall's (1978) consumption function implies a periodic autoregressive model with a unit root. Using quarterly seasonally unadjusted consumption for Australia, the United Kingdom, and Germany, recently developed tests for seasonality and periodicity are used to examine the modified rational expectations life-cycle permanent income hypothesis and to reinforce previous findings in the literature. Seasonal habit persistence is introduced as an alternative model and its empirical adequacy is found to be significant. Finally, a multivariate test of the excess sensitivity puzzle excludes a predictive role for lagged income changes.     

Coping with an emerging market competition through strategy-human resource alignment: case study evidence from five leading Japanese manufacturers in the People's Republic of China

This paper documents how PRC-based Japanese affiliates can align their human resource management (HRM) policies and practices with their business strategies based on in-depth interview surveys of the five leading Japanese manufacturers in China. In particular, using a multiple-informant research design to interview both top and human resource managers in each site, the study has attempted to clarify the strategic fit between the business strategies pursued and HRM practices adopted in China. Our interviews with top management for each affiliate revealed three types of business strategies that the PRC-based affiliates adopt to gain competitiveness in the Chinese market. Separate interviews with HR managers further clarified that affiliates' HRM efforts are aligned with the strategy each affiliate is pursuing. The findings are used to suggest several hypothesized relationships between the particular strategies pursued and the HRM practices adopted in China. Furthermore, this study has provided some important insights as to how the choice of affiliate-level business strategies in China affects the ‘hybridization’ processes of the HRM policies and practices used in the cross-national business environment.     

Nexus between visitor arrivals and residential property rents in Hong Kong

The cost of living in Hong Kong is among the highest in the world. This paper investigates the effect of tourist arrivals on the residential property market in Hong Kong. It is demonstrated that the soaring number of tourists from Mainland China is pushing up property rents in Hong Kong. The substantial accommodation need generated by the increasing number of students from China is another contributing factor.
