Oil Prices and Personal Consumption Expenditures: Does the Source of the Shock Matter?

This paper studies the effect of structural oil shocks on personal consumption expenditures (PCE). First, we estimate a nonlinear simultaneous equation model, compute impulse responses by Monte Carlo integration, and conduct a test of the symmetry of the impulse response functions. We find that aggregate PCE responds asymmetrically to positive and negative oil‐specific demand shocks. Second, we find that aggregate PCE responds negatively to positive oil demand shocks, while adverse oil supply shocks are of limited effect. Third, we find important heterogeneity in the magnitude, sign and timing of the disaggregate PCE responses to structural shocks in the crude oil market. Our results clearly indicate that the response of PCE to an unexpected oil price increase depends on the source of the oil price shock. Our findings are robust to different nonlinear transformations for the real price of oil.     

Modeling producer responses with dynamic programming: a case for adaptive crop management

Past research found agricultural producers’ conditional responses during the growing season are important adaptations to weather and other stochastic events. Failing to recognize these responses overstates the risks confronting producers and understates their ability to respond to adverse circumstances. Dynamic programming (DP) provides a means for determining optimal long‐term crop management plans. However, most applications in the literature base their analysis on annual time steps with fixed strategies within the year, effectively ignoring conditional responses during the year. We suggest an alternative approach that captures the strategic responses within a cropping season to random weather variables as they unfold, reflecting farmers’ ability to adapt to weather realizations. We illustrate our approach by applying it to a typical cereal farm in Karak, Jordan. The results show that including conditional within‐year responses to weather reduces the frequency of fallowing by 23% and increases expected income by 9%.     

Electricity Tariff Changes and Consumer Sentiment on Household Consumption Expenditure in Malaysia

Purpose

This study investigates the impact of the current electricity tariff, represented by optimized tariff calculation, on Malaysian household’s consumption across different levels of income.

Design/methodology/approach

The input-output (IO) model has vastly been used in many energy economics literature that presented the matrix of production between various sectors in an economy. This study aggregated the 124 subsectors in IO Price Table 2015 into 12 groups of consumption of goods and services based on Household Expenditure Survey 2019 (HES 2019) to meet the study’ objectives.

Findings

This study found that in all simulations, high-income earners would be highly affected by the tariff changes. The lower the increment level in electricity tariff rate, the lower the magnitude would be on the changes of household expenditure level.

Research limitations/implications

Optimization in electricity tariff consumptions can pattern the Malaysian household’s consumption across different levels of income efficiently.

Practical implications

Useful to all consumer in the Malaysia economic business sector to predict their energy consumption up to optimum level.

Social implications

The study’s findings can benefit the society in optimiza their electricity consumption since everyone requires the energy for basic needs in their life.

     

Income distribution and the economy: Evidence from the vector autoregression model

Using the vector autoregression model, this research explores the impact of income concentration on GDP. The estimated results of the model and its impulse response confirm earlier studies which used different methodology or different data sets indicating that a higher concentration of income adversely affect GDP in the short run, although the effect turns positive in the long run.     

Consumer ethics: moral ideologies and ethical beliefs of a micro-culture in the US

This study explores the ethical ideologies and ethical beliefs of African American consumers using the Forsyth ethical position questionnaire (EPQ) and the Muncy–Vitell consumer ethics questionnaire (MVQ). The two dimensions of the EPQ (i.e. idealism and relativism), and gender were the independent variables and the four dimensions of the MVQ (i.e. illegal, active, passive and no harm) were the dependent variables. A sample of 283 students from a historically black university was used to explore the relationship between the independent and dependent variables. Findings suggested that consumers who scored higher on the idealism scale and lower on the relativism scale were more likely to reject questionable activities. On average, females expressed more willingness to reject questionable activities than males.     

2008 DMEF Customer Lifetime Value Modeling (Task 2)

We describe our approach for predicting individual donor's total gift amount over a two-year target period. We divide the donors into 8 segments; for each segment, we fit a logit model for predicting the probability of giving, and a log-linear model for predicting the amount of gifts conditional on a donor giving. We found that recency, frequency, and first gift amount are good predictors of the probability of giving, while time-weighted total gift amount in the past years is a good predictor for future gift amount.     

Organizational Ethics in Developing Countries: A Comparative Analysis

Relationships with one’s employees, co-workers, or superiors create ethical dilemmas. Employees’ judgments and ethical perceptions have been extensively studied in Western cultures, but not in developing countries. The purpose of this investigation is to examine employees’ self-reported work-related ethics and compare them to their perceptions of co-workers’ and top managements’ along various morally challenging situations in three developing countries’ organizations. Saudi Arabia, Kuwait, and Oman, known as the Gulf countries, were selected as the research setting – and provided the sampling frame – for this study. The results suggest that respondents perceived all ethically challenging situations as unethical and had significant differences among themselves regarding the ethical perceptions of self, as compared to perceptions of peers’, and top managements’. Discussion of the results and implications are provided.     

The internationalization of an Arab bank: The case of Ahli United Bank of Bahrain

Ahli United Bank of Bahrain (AUB) has “leapfrogged” over early stages of internationalization by means of multiple rapid acquisitions of competitors. Use of this high‐cost, high‐risk strategy is well known among companies with the resources to invest in international expansion, but its application has not yet been studied in depth among companies based in the Middle East. This theory‐driven case study examines the growth record of AUB, its place in the regional banking industry in the Gulf, and its successful internationalization as an Arab bank. The article concludes with a detailed assessment of managerial and theoretical implications arising from the case study, and proposes further research to understand better the process of internationalization by companies expanding from a base in the Middle East. © 2011 Wiley Periodicals, Inc.     

Demand for and Assessment of Audit Quality in Private Companies

Financial statement audits are mandated in most countries, thus making it difficult to distinguish between auditing driven by private incentives versus that driven by regulation. Who would ask for an audit, and how would its quality be assessed in the absence of regulation? Many private companies in Canada get their financial statements audited even though the law does not require it. In this field study, we conduct interviews to discover reasons for demanding an audit, and criteria used to assess their quality. Our study reveals that both internal stakeholders (management, boards, and employees) as well as external stakeholders (customers, banks, and private equity firms) request audits. Users evaluate audit quality based on a variety of criteria such as the auditor's accounting expertise, the absence of errors, the fees involved, risk assessments offered, allocation of effort, internal control, and general business advice. Implications for audit regulations are discussed.
