Managerial Overconfidence,Self-Attribution Bias,and Downwardly Sticky Investment: Evidence from Korea

The extant literature on behavioral corporate finance has explored the effects of overconfidence on investment–cash flow sensitivity (ICS) to explain overinvestment, yet it has overlooked the asymmetric behavior of investments in relation to changes in cash flow levels. This study examines whether investments behave asymmetrically responding to changes in cash flows and, if so, how managerial overconfidence affects asymmetric ICS. Using a sample of KOSPI and KOSDAQ firms in Korea, we find the incidence of downwardly sticky ICS in unconstrained firms. We then find that overconfident managers encourage ICS to be stickier than their rational peers do in unconstrained firms. Finally, we find that managerial overconfidence intensified by self-attribution bias induces ICS to get even stickier, suggesting more explicit evidence of corporate investment distortions. The results of alternative tests using the asymmetric models of Homburg and Nasev (2008) are qualitatively consistent with prior results. Overall, our findings imply a higher incidence of excessive investment commitments driven by overconfident managers.     

A method for reducing information asymmetry in destination–airline relationships

We propose a measure of business risk in air travel demand at the route level that can reduce information asymmetry during route development negotiations between tourism destinations and airlines. Aviation-exposed risk (AER) conveys information about the level of uncertainty with regard to air travel demand from an airline’s perspective. Using AER, tourism destinations and air service development teams can evaluate their risks from the perspective of the airline and its network. From there, an assessment can be made as to the value of air services in certain circumstances, including whether a direct underwrite or risk share between airlines and destinations is viable and necessary. By applying a portfolio analysis to an airline’s network, we find evidence that AER does indeed mimic the actual capacity distribution of the network. This provides support for AER as a useful risk measure to be used in practice.     

Examining the influencing factors of intention to share accommodations in online hospitality exchange networks

ABSTRACT

CouchSurfing is a free social-network-based online hospitality exchange network, aptly representing a new sharing economy phenomenon. Based on social capital theory and previous literature, this study attempts to answer why hosts help strangers without any expected economic benefit within online hospitality exchange networks. An empirical study based on a Web survey conducted with CouchSurfing hosts reveals that the most identified antecedents (enjoy helping, shared narratives, desire to make friends, and reciprocity) are significantly related to hosts’ intention to share accommodations. Interestingly, the overshadowing effect of trust in CouchSurfing on the intention to share accommodations is also found.     

Promoting cost efficiency and uniformity in parcel delivery centre locations and service areas: a GIS-based analysis

This paper provides a systematic framework to determine local delivery centre (LDC) locations and service areas to reduce delivery costs and balance the allocation of parcel delivery loads to promote sustainable LDC development. Based on a case study of a parcel distribution company in Korea, this study proposes two strategies for LDC service area delineation within each terminal service boundary that either minimises the total delivery time or balances the allocation of delivery loads. This research contributes to improving cost efficiency and balancing delivery load allocations in planning LDC locations and service areas that can potentially promote the long-term mutual sustainable development of parcel distribution companies and their local delivery counterparts.     

Can a Celebrity Serve as an Issue‐Relevant Argument in the Elaboration Likelihood Model?

While celebrity endorsement has been traditionally perceived as a peripheral cue in the elaboration likelihood model, several conceptual studies suggest otherwise that it may play a significant role in delivering issue‐relevant information when celebrity–product congruence exists. The current study provides empirical evidence that a celebrity indeed serves as an issue‐relevant argument by investigating the interaction effects between endorser–product congruence and product involvement on consumer responses in two different match‐up conditions. Moderated regression analysis results indicated that product involvement strengthened the effect of expertise‐based endorser–product congruence on consumer responses. However, the relationship between attractiveness‐based endorser–product congruence and consumer responses generated insignificant results. Research findings entail that a celebrity persuades consumers through the central route when the expert image in particular fits well with the endorsed product. Further analyses indicated that attitude toward the brand mediated the relationship between attitude toward the advertisement and purchase intention in both match‐up environments.     

Estimation of semiparametric locally stationary diffusion models

This paper proposes a class of locally stationary diffusion processes. The model has a time varying but locally linear drift and a volatility coefficient that is allowed to vary over time and space. The model is semiparametric because we allow these functions to be unknown and the innovation process is parametrically specified, indeed completely known. We propose estimators of all the unknown quantities based on long span data. Our estimation method makes use of the property of local stationarity. We establish asymptotic theory for the proposed estimators as the time span increases, so we do not rely on infill asymptotics. We apply this method to interest rate data to illustrate the validity of our model. Finally, we present a simulation study to provide the finite-sample performance of the proposed estimators.     

Online distribution of airline tickets: Should airlines adopt a single or a multi-channel approach?

In today's digital world, airlines typically distribute tickets both via their own websites and through online travel agency (OTA) platforms such as Expedia and Travelocity. Although associated with higher distribution costs, selling tickets through the platforms offers airlines exposure to a broader consumer base, and potentially higher sales than selling tickets solely through their own websites. While most airlines have adopted a multi-channel approach by selling tickets through OTA platforms and their websites, some (e.g., Southwest Airlines, easyJet and Ryanair) sell only via the latter. Is one approach better than the other, and if so, under what circumstances? This study analyzes factors that affect an airline's distribution strategy by developing a decision support model. We find that airlines are less likely to use OTA platforms if they have a large loyal consumer base or if the OTA platform is highly competitive.     

Identifying Macroeconomic Linkages to U.S. Agricultural Trade Balance

This study explores the short-run and long-run relationships between the U.S. agricultural trade balance and domestic macroeconomic aggregates and agricultural variables. We use cointegration analysis and a vector error-correction model with quarterly data for 1981–2003. The results show that, in the long run, the exchange rate, agricultural price, and disposable income are weakly exogenous in the U.S. agricultural sector and have significant effects on the trade balance. The combined short-run dynamic effects of the exchange rate, agricultural price and production, and the disposable income jointly explain changes in the trade balance.
La présente étude porte sur les liens à court et à long terme entre la balance commerciale agricole des États-Unis, les agrégats macroéconomiques et les variables agricoles. Nous avons utilisé une analyse de cointégration et un modèle vectoriel à correction d'erreur comprenant des données trimestrielles de 1981 à 2003. Les résultats ont montré que, à long terme, le taux de change, les prix agricoles et le revenu disponible sont faiblement exogènes dans le secteur agricole des États-Unis et qu'ils ont des effets substantiels sur la balance commerciale. Les effets dynamiques à court terme combinés du taux de change, des prix et de la production agricoles ainsi que du revenu disponible expliquent les changements observés dans la balance commerciale.     

Consumption and Portfolio Selection with Labor Income: A Continuous Time Approach

This paper studies the consumption and portfolio selection problem of an agent who is liquidity constrained and has uninsurable income risk. The paper investigates how the optimal consumption and asset allocation policies deviate from the case where the financial market is perfect, i.e., the case where there are no liquidity constraints and uninsurable income risk. In particular, the paper shows that, for a given level of financial wealth and labor income, optimal consumption is smaller and the optimal level of risk taking is lower in the case where the agent is liquidity constrained and has uninsurable income risk than in the case where the financial market is perfect. The paper also discusses how the agent assesses the value of lifetime labor income and relates this evaluation to optimal consumption and asset allocation policies.
