Sensation seeking and the prediction of attitudes and behaviours of wine tourists

Although socio-economic variables are commonly used for market segmentation and are widely applied in describing winery visitors, increasing awareness is evident in the literature that personality might also be useful for that purpose. The present study examined whether, compared with socio-economic variables (age, gender, education level, personal income, and household income), the personality variable sensation seeking adds to the ability to predict differences in various attitudes and behaviours of wine tourists. With the effects of the former controlled, sensation seeking was observed to be significantly related to spending on wine, and wine drinking, as well as to the frequency of visits to wineries and the number of activities engaged in at wineries, the use of the internet as a source of information about wineries, venturing off the beaten track during a visit to a wine region, and the strength of opportunity for learning, stimulation, or indulgence as incentives to visit a wine region. Sensation seeking was also observed to be significantly related to all but one of those variables when the effects of another variable which is receiving increasing attention as a means by which to characterize wine tourists, “involvement”, were controlled. The practical significance of the results for winery and wine region marketing and management is discussed, and several requirements for further research are identified.     

Private Information and the Exercise of Executive Stock Options

This paper finds strong evidence that executives use private information when exercising their stock options. The most informed executives tend to exercise early, do not exercise on the vest date, do not exercise to capture dividends, exercise a high percentage of their options, and exercise when the option is the least in‐the‐money. We also find that exercises around resignation and retirement are followed by significant negative abnormal returns. Furthermore, the operating performance of firms following exercises motivated by private information is significantly worse than that of firms in which the exercises are not motivated by private information.     

Not all Codes are Created Equal: The Software Engineering Code of Ethics, a Success Story

There has been a transition in the way software developers work. Mistakes in software have been treated as "normal" occurrences. "All software has bugs." However, software engineering is an emerging profession which as a profession has now said that a caviler approach to software errors is unacceptable. They have asserted a very strong ethical position in the Software Engineering Code of Ethics and Professional Practice, a position which mandates concern for all those affected by their work. The Code has several unique elements as a professional Code.

Market index depository liabilities: Analysis,interpretation, and performance

This paper examines a new financial instrument, the market index CD. This deposit offers an interest rate equal to a specified fraction of the change in the stock market over the life of the CD with a guaranteed minimum. We present a pricing formula, an examination of the effects of underlying variables, an evaluation of the early redemption feature, empirical results on the historical performance, and a discussion of some issues suggested by the introduction of this product.     

Damping seasonal factors: Shrinkage estimators for the X-12-ARIMA program

We examine the effect of damping X-12-ARIMA's estimated seasonal variation on the accuracy of its seasonal adjustments of time series. Two methods for damping seasonals are proposed. In a simulation experiment, we generated time series data for each of 90 distinct experimental conditions that, in aggregate, characterize the variety of monthly series in the M3-competition. X-12-ARIMA consistently overestimated the actual seasonal variation by an amount consistent with statistical theory. Damping seasonals reduced X-12-ARIMA's estimation error by as much as 79% and under no conditions was estimation error increased beyond a trivial amount. Improvement depended primarily on the degree to which random variation in a series dominated seasonal variation. When the multiplicative X-12-ARIMA model did not match the data-generating model, overestimation was less for trend series than for series with no trend; otherwise the presence of trend had no discernible effect. One of the proposed methods was somewhat more accurate and robust, but more complex, than the other. In an analysis of real data—the 1428 monthly series of the M3-competition-damping X-12-ARIMA seasonals prior to forecasting (1) reduced the average forecasting MAPE by 4.9–1.4% and (2) improved forecasting accuracy for 59–65% of the series, depending on the forecasting horizon. This research suggests that damping X-12-ARIMA seasonals leads to more accurate seasonal adjustments of time series, thus providing a more reliable basis for policy-making, forecasting, and the evaluation of forecasting methods by researchers.     

The Sale of Assets to Manage Earnings in Japan

In this article we investigate Japanese managers' use of income from the sale of fixed assets and marketable securities to manage earnings. The earnings management target examined is Japanese managers' forecasts of current–year earnings. We find a negative relation between income from asset sales and management forecast error. When current reported operating income is below (above) management's forecast of operating income, firms increase (decrease) earnings through the sale of fixed assets and marketable securities. The results hold after controlling for expected future performance, debt–to–equity ratio, size, growth, and last year's income from asset sales.     

Association between environmental factors and equity market performance: evidence from a nonparametric frontier method

In this cross-sectional study, equity market performance is assessed in a multidimensional risk-adjusted return framework using a nonparametric procedure known as data envelopment analysis. Employing a censored regression procedure, the association between equity market performance and a set of variables that proxy market characteristics and the political and business environment in which the market operates is investigated. The paper contributes to the literature on the association between environmental factors and equity market performance by using a methodology not previously employed in such investigations. The results reveal that equity market performance may be positively related to the size of the market and friendliness of the business environment. Friendliness of the business environment is an objective measure of regulations conducive to business and their enforcement.
