     A Review of Overconfidence in Behavioral Finance

Author (s)

Ramon Joffre Alan Pires

Abstract

Behavioral finance can be dichotomized into limits to arbitrage and cognitive psychology. While limits to arbitrage describes when markets are inefficient, cognitive psychology refers to how people think. In this review we focus on one well-established bias of cognitive psychology, namely overconfidence. Throughout the literature there are three distinct ways in which overconfidence has been defined: (1) overestimation, (2) overplacement and (3) overprecision. We shortly summarize the ideas of conventional theory about overconfidence, and present the most significant findings of the relevant literature. Hereby we differentiate between studies that investigate overconfidence on the micro level (i.e. individual-level data) and the macro level (i.e. aggregated-level or market-level data). We will also discuss inconsistency across different measures of overconfidence and the reverse phenomena of overconfidence, i.e. underconfidence. To stay within the scope of this work we place our main focus on experimental studies.

Key words: overconfidence, behavioral finance, investor psychology, financial markets, review.

Abstract

The advents of the internet and e-commerce have transformed the pattern of purchase of goods and services. Online customers find online shopping very convenient, flexible, time saving, offering a wide variety of selection, cheaper products and provide the possibility to make private purchases easier. Despite the numerous benefits of online purchasing platforms, the adoption rate is low in Uganda. This study aimed at modeling a framework on determinants of customers’ intentions to purchase online in the case of Kampala Uganda. The philosophical underpins were both positivism epistemology and objectivism ontology. Data was sourced using structured questions from a sample of ninety-seven (97) online customers’ in Kampala. The analysis was concluded using Structural Equation Modeling (SEM) and the findings revealed that; Facilitating Conditions (FC), Service Quality (SQ) and Customers’ Attitudes (A) have positive significant impacts on online purchase intention whereas, there was insignificant statistical evidence to suggest that System Quality (SQ) influences the intention to purchase online. This study therefore recommends managers of online businesses to consider Service Quality (SeQ), Facilitating Conditions (FC) and Customers Attitudes (A) as critical determinants to improve online sales. Indicators such as: timely deliveries, product conformability and prompt feedback are drivers to online purchase intentions. This study provides emerging views essential in managing relationships between businesses and customers with the intention to model successful e-business strategies. This research thus provides a useful insight to parties including e-business practitioners, government and customers on the role of e-commerce adoption in Uganda.

Key words: Online Purchase, Online Purchase Intention, Customer, e-commerce, Uganda.

Author (s)

WonJoung Choi

Abstract

As the globalization pressures the companies to expand multi-nationally, the human resource management (HRM) issues are becoming more challenging with cultural factors involved. A growing literature emphasizes that HRM play important part in the success of MNCs. Then what are the HR practices that attracts local staff? What is the belief of local staff that MNCs will provide to them? This research uses the concept of psychological contract to search the answers of above questions by investigating the dynamics of local staffs working for MNCs in Korea. The qualitative methods by conducting in-depth interviews from 9 local staffs and organizing focus group meetings at the Korean subsidiaries of oversea are executed to analyze the psychological aspects of the workers. The performance base rewards and its home country cultures were one of several factors that influenced psychological contract. The change of contract and causes of psychological contract violation is also examined. Recommendations generated from the findings are drawn for MNC HR managers.

Key words: psychological contract; cross-cultural management; multinational companies; international business research; performance base rewards.

Ethical Leadership and Knowledge Management Behaviors: Role of Organizational Citizenship Behavior and Procedural Justice

Author (s)

Khola Masood

Abstract

A growing body of literature is focused on analyzing the impact of leadership styles on various organizational behaviors. Although in knowledge management literature studies have shown a statistically significant impact of any leadership style on knowledge sharing but the literature on hiding is still scarce. This study is an attempt to bridge this gap in literature by focusing on ethical leadership and the impact it has on the knowledge sharing and knowledge hiding of the employees. Organizational citizenship behavior is included as mediator in the study as it is observed from past literature that employees like to emulate the behavior of their supervisor. The model of the research study also suggests for the moderation effects of procedural justice. Ethicality of the leader results in higher organizational citizenship behavior which in turn enhances the knowledge sharing and hinders the knowledge hiding behavior of the employees. It was also found that procedural justice moderates the relationship.

Key words: Ethical leadership, knowledge hiding, knowledge sharing, organizational citizenship behavior, procedural justice.

A Qualitative Research on Zambian Work Values: A Theoretical overview from an Intrinsic and Extrinsic Point of View across Generations

Author (s)

Mulele Simasiku

Abstract

This paper aims to explore and elaborate on Zambian work values, of which a mixture in traditional and western values has been the focal point of the daily life of Zambians. This paper will use qualitative research methods and empirical observations from participants to shade more light on Zambian work values. This paper also aims to highlight on the intrinsic and extrinsic values that encompass work values. Twenty Zambian employees at different companies in different sectors were interviewed to build findings on this construct. Questions on intrinsic work values and extrinsic work values were asked to them in interview style for them to shade more light to which category they thought they inclined to and their justification of such a way of being. After which they were administered a work value questionnaire, for more brief and confined answers. Both the questionnaires and the data from the interview responses were used to draw conclusions.

Key words: Work values, culture, intrinsic, extrinsic, generations.

Abstract

The seam strength and seam efficiency of 2/1 twill woven fabric has been investigated all through the research where a variety of 20/2, 27, 30, 40, 40/1, 40/2 and 40/3 thread count were applied individually for superimposed, lapped and bound seam respectively. After preparation, each of the samples, brought into the tensile strength test and the breaking strength and efficiency were measured. For each case, seam strength increased with the increase of SPI at a constant thread count. The lowest seam strength and efficiency were achieved for samples sewed with 27Tex sewing thread, and the maximum value was achieved for samples which were stitched by 40/3 count.

Key words: Stitch density, thread count, 2/1 twill fabric, strength and efficiency.

Abstract

Humans are exposed to chromium ions from leather materials owing to everyday contact with different need based activities. The concern is that Cr (VI) is extremely toxic and may cause contact allergic dermatitis on the skin and may also be a trigger for a plethora of diseases, hence it is essential to monitor the presence of chromium as Cr (VI). For the determination of levels of chromium (VI) the shaving dust samples from four different tanneries and chrome liquor, and wet blue leather trimmings from three different tanneries were collected.  The fat content was determined in collected shaving dust and wet blue trimmings with the aid of Soxhlet extraction method using petroleum ether- ethanol solvent. Then the extraction of Cr (VI) from the samples was done following the standard procedure of society for Leather Chemistry with some modification. Afterwards, UV- visible spectrophotometric determination of Cr (VI) was carried out through the complex formation with 1, 5-diphenylcarbazide (DPC).  The weight percentages of fat content were found to be in the range of 2.98-3.71. Analytical grade potassium-dichromate reagent was used as a standard source of Cr (VI) in calibration process. Among the collected four shaving dust samples in three samples were found to contain Cr (VI) in the range of 1.96-2.19 mg/kg. In three analyzed wet blue trimmings samples the Cr (VI) was found to be from 1.59 to 1.86 mg/L.   The amount of hexavalent chromium was found 1.27 mg/L in one chrome liquor sample out of three samples.

Analysis of Fiscal Policy and Fertility in Provincial Government of Indonesia

Author (s)

Oktarini Khamilah Siregar

Abstract

This research aims to analyze whether fiscal policy affects the fertility of the Provincial Government Indonesia using panel data with time series from 2007 to 2017, a cross-section of 33 Provincial governments in Indonesia. Fertility is measured using Total Fertility Rate (TFR) and Birth Rate. Local revenue, regional expenditure, and regional debt do not affect TFR but the regional deficit negatively does. Regarding the birth rate, regional income and deficits have a positive effect, regional expenditure has a negative effect, but regional debt does not affect birth rates in 33 provincial governments in Indonesia. The equivalent ricardien theory does not apply to this study because households do not assist provincial government policies caused by high fertility. As a result, national TFR is not achieved and will affect sustainable fiscal deficits.

Key words: Total Fertility Rate, Birth Rate, Local Revenue, Regional Expenditure, Regional Debt dan Regional Deficit.
