Sad or Happy? The Effects of Emotions on Stated Preferences for Environmental Goods

A substantial literature in behavioural science and psychology shows that emotions affect human choices and values. This paper investigates whether such emotional impacts are also present in stated choice experiments for environmental goods. If this were so, it would introduce an additional element of context dependence to the welfare measures derived from such methods, and would be at odds with the rational choice model underlying welfare economics. A laboratory experiment using three different emotion treatments was combined with a stated preference choice experiment concerned with changes in coastal water quality and fish populations in New Zealand. No statistically significant effects of changes in emotional state on estimated preference parameters, willingness to pay or the randomness of choices were found. The paper concludes by questioning, why such a contrast exists with empirical findings in behavioural science.     

LONG‐RUN INEQUALITY AND SHORT‐RUN INSTABILITY OF MEN'S AND WOMEN'S EARNINGS IN CANADA

This paper examines the variability of workers’ earnings in Canada over the period 1982–2006. We decompose the total variance of workers’ earnings into a ‘permanent’ component between workers and a ‘transitory’ earnings instability component over time for given workers. We then investigate the statistical relationships between these components and indicators for the business cycle. The most marked change in earnings variances in Canada since 1982 is the general rise in total earnings variance, which is essentially driven by a quite dramatic rise in long‐run earnings inequality. The patterns across age categories of the two variance components are almost opposite. Long‐run earnings inequality generally rises with age, but earnings instability is seen to generally decline with age, so that earnings instability is markedly highest among entry age workers. Unemployment rate effects are positive on almost all variance measures, while higher unemployment is associated with widened long‐run earnings differentials and greater short‐run earnings instability.     

Opportunity Cost for Free Allocations of Emissions Permits: An Experimental Analysis

An important feature of emissions trading is how emissions permits are allocated. The choice between an auction and free allocation should not influence firms’ production choices nor consumer prices according to economic theory. However, many parties expect the method of allocation to affect product prices. This paper describes an experimental investigation into price determination under a cap-and-trade program with different allocation methods. Participants initially display diverse pricing strategies. However, given a simple economic setting in which earnings depend on behavior, we find that subjects learn to consider the opportunity cost of permits and overall behavior moves toward the economic prediction.     

Aggregation of Efficiency Indices

Measurement of technical efficiency is carried out at many levels of aggregation—at the individual branch, plant, division, or district level; at the company- or organization-wide level; at the industry or sectoral level; or at the economy-wide level. In this paper, we examine the conditions under which these indexes constructed at various levels of aggregation can be consistent with one another—that is, the extent to which efficiency indexes can be consistently aggregated. Unfortunately, our results are discouraging, indicating that very strong restrictions on the technology and/or the efficiency index itself are required to enable consistent aggregation (or disaggregation).     

In the air again: frequent flyer relationship programmes and business travellers' quality of life

This research explores whether frequent flyer programmes somehow add to the quality of life of the frequent business traveller (defined in this study as business flyers who had flown round trip 26 or more times in the past 12 months). A questionnaire was mailed to subscribers of a newsletter for members of frequent air and hotel programmes. Results indicated that frequent flyer programmes contribute positively to frequent business travellers' lifestyles and to their quality of life, perhaps by countervailing some of the negative aspects of frequent business travel.

Rookies and seasoned recruits: How experience in different levels,firms, and industries shapes strategic renewal in top management

Research summary : This study explores the effect of knowledge integration on strategic renewal. In particular, it examines how executives from different levels and sources influence renewal when added to top management teams (TMT). In contrast to prior work, the study hypothesizes and finds that new outside rookies—those new to top management and the firm—are associated with higher firm growth than other types of executives. We also find that seasoned outsiders—those with prior TMT experience outside the focal industry—contribute to growth only when the existing TMT has a long tenure. The results suggest that the ability of the TMT to integrate new members varies by executive type and has an important effect on incremental strategic renewal. Managerial summary : Conventional wisdom holds that firms are better off hiring those who can demonstrate prior experience and skill in tasks as close as possible to the job. In the realm of the top management team (TMT), however, we find that many firms benefit from hiring rookies from other firms who are new to the top management team level. These candidates bring useful knowledge of the operations of competitors and other firms, and they are easier to socialize and integrate with the existing team. While more experienced senior leaders may bring valuable strategic knowledge, this study suggests that only top management teams with long shared experience can weather the disruption that they cause to realize the potential benefits.

Decompositions of corn price effects: implications for feed grain demand and livestock supply

This article examines how corn prices affect the demand for feed grains and the supply of livestock outputs. The differential approach to the theory of the multiproduct firm is employed to examine ex ante decisions about feed grain demand and livestock supply. The estimation results suggest that livestock producers have little flexibility in adjusting the demand for corn in response to an increase in corn prices. The substitutable relationship between corn and distillers’ grains contributes to alleviating pressures on feed costs in response to high corn prices. In addition, the estimation results highlight that the composition of livestock supply can be altered by changes in livestock prices. On the basis of the estimated elasticities, the decompositions of profit‐maximizing input demand are conducted to examine the effects of changes in corn prices on feed grain demand and livestock supply. The decomposition results reveal that an increase in corn prices reduces corn demand but raises the demand for distillers’ grains mainly due to the substitution effects of corn price changes. The decomposition results also show that an increase in the price of corn reduces cattle supply but raises the supply of chicken and pork due to the output relationships in supply.     

Agricultural market policy reforms and growth in Nigerian export crops

The paper investigated the prospect of selected export crops in meeting the demand of emerging commodity and futures market in Nigeria within the context of a counterfactual model, The data covered about three decades （1973-2000）. The model was estimated to capture two economic policies in the period namely stabilization （1973-1985） before introduction of Structural Adjustment Programme （SAP） and liberalization policy （1986-2005） that followed SAP The results indicated positive divergence between factual and counterfactual trends for palm kernel, cocoa, coffee and rubber but neuative for groundnut after SAP
