Household tax evasion

Household members share public goods and make intra-household transfers. We show how these features of the household interact with the tax evasion decision, and identify the dimensions in which household evasion differs from individual evasion. In the model we present two members of a household choose how much to contribute to a household public good and how much self-employment income to evade. We are interested in how different evasion possibilities interact with the contribution decisions to the household public good and the role of income transfers within the household. We show the household evasion decision differs from the individual decision because it affects the outcome of the household contribution game. When household members are taxed as individuals neutrality applies when choices are not constrained. If the evasion level of one household member is constrained then an income transfer can generate a Pareto improvement. When the household members are jointly taxed there is a couple constraint on strategies and corner solutions can emerge.     

Civic participation of secular groups in Canada

Using two recent nationally representative Canadian surveys, this paper investigates how secularization affects civic participation, inclusive of political engagement and philanthropy. Three mutually exclusive categories of secularized individuals are considered. The analysis suggests that Canadian secular groups are relatively less engaged with politics and volunteer fewer hours, compared with the actively religious. They are, however, found to contribute significantly more money to secular causes, controlling for a wide range of individual attributes. Various explanations are explored.     

Demand estimation for the Iranian automobile industry

The main contribution of this paper is a simple theoretical framework and empirical estimations explaining the behavior of the manufacturers. The paper focuses on the frequently used methods of demand estimation for discrete choice models to analyze the Iranian automobile market. It shows how both major companies in Iran choose to produce lower quality products and why they still collusively charge high markups. Empirical estimations are based on Berry, Levinsohn, and Pakes (1995) to predict marginal costs and markups. Estimation results also support the hypothesis that manufacturers are charging high markups. In addition, the counterfactual analysis carried out supports the view that both duopolist firms prefer to operate at lower quality rather than at higher quality production levels. They also collusively price their products. Furthermore, analyses are performed using the Multinomial Logit methodology to better understand the Iranian automobile market. Tastes of people with different genders and ages for some specific cars are explained, and the effects of population changes on auto demand are predicted.     

Factors influencing food-choice behavior of African-American college students: implications for the foodservice industry

College students, particularly ethnic minorities in the US, are at a high risk for obesity and health complications. This study determines the type of foods that African-American college students are choosing to eat, and what factors influence those choices. Findings show that fresh fruits, whole grain bread, grilled chicken, and salad top the list of food choices. Knowledge of nutrition labels, gender, weight management, and eating facilities are among the factors found to influence these choices. Managerial implication of findings for the foodservice industry, and other interest groups are discussed. Directions for future research are given.     

Religiosity and social trust: evidence from Canada

Using the latest wave of the Canadian Ethnic Diversity Survey, I investigate whether religious identity and religious intensity associate with the degree to which people trust others, controlling for a wide range of characteristics. The analysis shows that Canadian Roman Catholics are appreciably less trusting than mainline Protestants, and religious nones are situated in between these two groups. With regard to religious intensity, I find that higher commitment negatively correlates with trust in unknown others for Roman Catholics. The reverse is true for Protestants. Results also show stark cross-denominational variations within Protestantism, as two highly committed denominations of Mennonite and Pentecostal are found to be the most and the least trusting religious groups in Canada. No non-Christian religious minority is found statistically significantly less trusting than Canadian Roman Catholics. Considering particularized trust in one’s neighbours and co-workers yields comparable conclusions.     

D‐optimal designs for a continuous predictor in longitudinal trials with discrete‐time survival endpoints

In designing an experiment with one single, continuous predictor, the questions are composed of what is the optimal number of the predictor's values, what are these values, and how many subjects should be assigned to each of these values. In this study, locally D‐optimal designs for such experiments with discrete‐time event occurrence data are studied by using a sequential construction algorithm. Using the Weibull survival function for modeling the underlying time to event function, it is shown that the optimal designs for a linear effect of the predictor have two points that coincide with the design region's boundaries, but the design weights highly depend on the predictor effect size and its direction, the survival pattern, and the number of time points. For a quadratic effect of the predictor, three or four design points are needed.     

INTERACTIONS AMONG DIFFERENT DIMENSIONS OF A RESPONSIVE PUBLIC SPACE: CASE STUDY IN IRAN

A place is generally identified by its varying physical, activity, social and meaning (connotative) characteristics. In this paper, the "Model of Responsive Public Space" is defined by these four aspects and each of them has its own special indicators as shown in previous studies on this subject. To examine this model and evaluate the interactions between these dimensions, experimental studies were carried out in two stages. In the first stage, open-ended structured interviews were carried out with 70 participants to adjust the model with personal opinions about public spaces in Qazvin city, Iran. In the second stage a questionnaire was used to explore the effect of the four dimensions on each other. 598 users of a selected public space participated in this study. The results were analyzed by SPSS software applying a Pearson correlation test and Excel software. These results indicate that not only in theory but also in practice, public spaces have four distinct aspects that must be taken into consideration when creating a responsive public space. The most significance correlation is that between the meaning and the social dimension of public spaces.
