The reversing influence of involvement on the framing effect: The role of emotions and negativity

The Asian disease problem (ADP), as a demonstration of the framing effect, revealed a preference reversal between options perceived as risky and those perceived as certain. This research identifies individuals' involvement level as a moderator of the framing effect. The framing effect in the ADP consisted of emotional choice outcomes regarding human lives. Two studies in this paper demonstrate that when based on emotional choices, the framing effect in high involvement conditions increases in size. Interestingly, this influence of involvement reverses when the framing effect is based on rational choices. The studies reveal that the negativity invoked by the certain loss option is instrumental in the underlying mechanism of the risky choice framing effect, such as that demonstrated by the ADP.

Timing of earnings restatements: CEO equity compensation and market reaction

This study investigates the impact of chief executive officers’ (CEO) compensation on their choices regarding the timing of earnings restatements. The results indicate a negative relationship between options exercised and lags in disclosing the restated earnings, suggesting that managers who exercise options in a given year tend to release information quickly. This effect is more pronounced if the options are exercised after the dark period. We also find that the market penalises longer lags in the restatement disclosure. It seems that the CEO would try to optimise the timing of information release so as to balance the costs and benefits.     

Political instability and inflation in Pakistan

This study investigates the effects of political instability on inflation in Pakistan. Applying the Generalized Method of Moments technique and using data from 1951 to 2007, we examine this link through two different models. The results of the ‘monetary’ model suggest that the effects of monetary determinants are rather marginal and that they depend upon the political environment of Pakistan. The ‘nonmonetary’ model's findings explicitly establish a positive association between political instability and inflation. This is further confirmed through analysis based on interactive dummies that reveal political instability significantly leading to high (above average) inflation.     

Dissertation abstract: The effect of involvement, time, and vividness on consumers’ value judgments: A test of prospect theory

The literature in psychology and behavioral economics offers abundant instances of anomalies to the rational choice paradigm. One of the most prominent works attempting to reconcile these is Kahneman and Tversky’s Prospect Theory. Its well-known S-shaped value function accounts for some of the anomalies such as reference dependence, loss aversion, and diminishing sensitivity. Although Prospect Theory describes the manner in which individuals are loss averse, it does not explain why people show loss aversion. This dissertation investigates the factors that affect the cognitive processes behind loss aversion. We find an anomaly in the S-shaped value function. Specifically, the studies demonstrate that the degree of involvement affects the slope of the value curve both for atemporal and intertemporal choices. In addition, we also test the relationship between loss aversion and involvement with varying vividness of outcomes (i.e., when outcomes are related to more versus less vivid stimuli). Testing the vividness effects further extends and confirms our proposed relationship between involvement and loss aversion. The data from several experiments show that there is a difference in the slopes of the value function for low and high involvement decisions. For low involvement conditions, the value curve has roughly the same steepness for losses as for gains close to the neutral reference point (i.e., contrary to the diminishing sensitivity characteristic). By contrast, in the high involvement conditions this is not the case: there is a distinct difference in the slopes of the loss and gain curves. This leads us to propose that different value functions exist for people in the low and high involvement conditions. This important finding suggests that in cases where people are not highly involved with a product, they display significantly less loss aversion than predicted by Prospect Theory. Three experiments investigate the relationship of loss aversion to subjects’ level of involvement in atemporal choice, intertemporal choice, and differential vividness of stimuli situations, respectively. The first study uses a 2 (involvement: low and high) by 2 (outcome: gain and loss) between subjects design. The results show that loss aversion significantly attenuates in the low involvement condition for atemporal choice. Study two replicates the results of study one in the context of intertemporal choice, where timing of outcomes (now versus three months) is introduced as another factor. Finally, the third study manipulates the vividness of outcomes and finds an interaction effect of vividness and involvement on loss aversion. Dissertation Committee: Norman Frohlich (Co- Chair), I.H.

Impact of knowledge oriented leadership on knowledge management behaviour through employee work attitudes

Abstract

Despite the acknowledged importance of knowledge management (KM), many employees avoid practicing KM at the individual level. This avoidance often leads to loss of the intellectual capital due to employee turnover. Many potential behavioural remedies are still untapped in the existing literature. This study extends the construct of knowledge oriented leadership (KOL) and examines its role in predicting KM behaviour among employees of the hospitality sector, at the individual level. It also investigates the mediating effect of employee work attitudes including affective commitment, creative self-efficacy and work engagement, by using partial least square for structure equation modelling. This study finds that KOL positively affects KM behaviour, affective commitment, creative self-efficacy and employee work engagement. Work attitudes (affective commitment, creative self-efficacy, work engagement) mediate the relationship of KOL and KM behaviour. Furthermore the direct positive effect of employee affective commitment, creative self-efficacy and work engagement on KM behaviour is also significant. This study contributes to the body of knowledge by extending the construct of KOL, and by investigating the connection between KOL, work attitudes, and KM behaviour among hospitality employees, at the individual level.     

"Export Experience" under Borrowing Constraints

The paper develops a two‐period, two‐country, multigood model with endogenous investment. Borrowing is subject to quantitative restrictions. The authors examine the effect of promoting exports in period 1 on the level of exports in period 2. They consider a number of scenarios depending on how the initial values of the policy instruments are determined, and compare the “export‐experience” effects under the different scenarios.     

The product‐market performance benefits of environmental policy: Why customer awareness and firm innovativeness matter

Researchers have widely studied the nexus between corporate environmental (“green”) policy and its green performance and firm financial performance, but with mixed findings. A potential explanation for these mixed findings is the focus of extant studies on the direct and immediate impact of environmental performance on financial performance to the exclusion of firm‐specific boundary conditions. Furthermore, all prior research study the effect of environmental performance on either stock market‐based performance measures (i.e., stock return) or accounting‐based performance measures (i.e., return on assets). A missing third dimension of firm performance, product–market‐based performance (i.e., market share), has so far remained unexplored despite representing a crucial objective when innovating. Using Newsweek's annual green ranking as a novel measure of environmental performance for a panel of U.S. firms from 2010 to 2015, this paper attempts to fill these voids in the literature. The results show a positive relationship between firms' environmental performance and market share as a measure of product–market‐based performance. The findings further demonstrate that this relationship is positively moderated by the level of customer awareness and innovativeness of the firm: The higher the level of awareness of a firm's environmental credentials and innovativeness, the stronger the effects of environmental performance on market share. Our results are robust against endogeneity concerns and alternative measures of firm financial and environmental performance.     

Government Intervention and Investment Comovement: Chinese Evidence

This study examines whether government intervention affects corporate investment comovement, and whether this impact varies across firms with different types of ownership. We use a large Chinese sample to investigate these questions, and perform a regional as well as firm‐level analysis. We show that government intervention is positively and significantly associated with investment comovement. We also find that the impact of government intervention on investment comovement is higher and more significant for state‐owned firms than for domestic private and foreign firms. Finally, we show that investment comovement hinders corporate performance for state‐owned and domestic private firms but not for foreign firms.     

Against the tide: the commencement of short selling and margin trading in mainland China

China's recent removal of short‐selling and margin trading bans on selected stocks enables testing of the relative effect of margin trading and short selling. We find the prices of the shortable stocks decrease, on average, relative to peer A‐shares and cross‐listed H‐shares, suggesting that short selling dominates margin trading effects. Contrary to the regulators' intention and recent developed market empirical evidence, liquidity declines and bid‐ask spreads increase in these shortable stocks. Consistent with Ausubel (1990), these results imply that uninformed investors avoid the shortable stocks to reduce the risk of trading with informed investors.
