A three-stage model for smart phone use antecedents

Due to the widespread use of smart phones with enhanced functions, telecom service providers Have responded in a variety of contexts but have yet to attract enough customers as expected. Few studies have been conducted to understand antecedents for using smart phone mobile services in Taiwan. To acquire a better understanding of why people use smart phone mobile services, we used focus groups to investigate the smart phone consumption decision process. This study combined existing theories, Unified Theory of Acceptance and Use of Technology (UTAUT), perceived playfulness, with new factors discovered through focus groups, to develop a three-stage model for smart phone use antecedents. This model can be adopted by related operators and companies as a foundation for setting business strategies and marketing programs, and also as a reference for other researchers to examine the relationships in the model.     

The role of governance in mobile phones for inclusive human development in Sub-Saharan Africa

This study assesses the synergy effects of governance in mobile phone penetration for inclusive human development in Sub-Saharan Africa with data for the period 2000–2012. It employs a battery of interactive estimation techniques, namely: Fixed effects, Generalised Method of Moments and Tobit regressions. Concepts of political (voice and accountability and political stability/no violence), economic (government effectiveness and regulation quality) and institutional (corruption-control and rule of law) governance are employed. The following findings are established. The previously apparent positive correlation between mobile phones and inclusive development can be extended to a positive effect. Although political governance is overwhelmingly not significant across estimated models, the average effects from economic governance are higher relative to institutional governance. On the interactions between mobile phones and governance variables, while none are apparent in Fixed effects regressions, there are significant synergy effects in Generalised Method of Moments and Tobit estimations, notably, from: regulation quality in the former and political stability, voice and accountability and rule of law in the latter. There is consistent evidence of convergence in inclusive human development. Policy implications are discussed.     

LINGUISTIC STRUCTURES AND ECONOMIC OUTCOMES

Linguistic structures have recently started to attract attention from economists as determinants of economic phenomena. This paper provides the first comprehensive review of this nascent literature and its achievements so far. First, we explore the complex connections between language, culture, thought and behaviour. Then, we summarize the empirical evidence on the relationship between linguistic structures and economic and social outcomes. We follow up with a discussion of data, empirical design and identification. The paper concludes by discussing implications for future research and policy.     

MIGRATION THEORIES AND EVIDENCE: AN ASSESSMENT

Abstract. This paper presents a critical survey of theories of migration, their welfare and policy implications and their empirical relevance. We also develop some extensions to the theory beginning with the Harris and Todaro (HT) model. In particular, the HT model is extended to examine risk averse behaviour within families where the migration of members of families serves to diversify risk. The welfare implications of the individual migration decision and government intervention in the form of employment subsidies are examined. Recent evidence on international migration is presented. It is shown that migration does not flow automatically in response to wage differentials. Characteristics of migrants and the process of self-selection are found to be important determinants of the rate of migration.     

Are mobile and fixed broadband substitutes or complements? New empirical evidence from Italy and implications for the digital divide policies

The literature on broadband policies has been focusing on the possible role of mobile broadband as a means for addressing geographical digital divide in areas with no or inadequate fixed broadband infrastructure coverage. Broadband plans designed by most of the industrialized countries take the substitutability between fixed and mobile technologies for granted, with restrictions essentially relating only to bandwidth performance. We explore the determinants of individuals' private access (away from work) to the Internet with the smartphone through a mobile broadband connection, focusing on the role played by Internet uses and taking into account the availability of a fixed broadband connection at home. The results of our econometric exercise, carried out on microdata referred to Italian individuals, provide original and interesting evidence: a complementarity effect between mobile and fixed broadband is found for browsing, video streaming, gaming and cloud services; a substitution effect emerges for social networking and music streaming. Such increasing complexity of individuals’ broadband usage patterns should be acknowledged in the way broadband coverage is mapped and policies designed, adopting a more ecosystem-oriented approach which integrates supply- and demand-side features. A first step in this direction is the inclusion of some, so far neglected, key-attributes of the demand (data traffic allowance, latency, ease of interconnection with Internet capable devices) among the relevant dimensions of policy design.

THE ECONOMICS OF HEALTH AND SAFETY AT WORK: AN INTERDICIPLINARY REVIEW OF THE THEORY AND POLICY

Abstract This paper engages in an interdisciplinary survey of the current state of knowledge related to the theory, determinants and consequences of occupational safety and health (OSH). It first describes the fundamental theoretical construct of compensating wage differentials, which is used by economists to understand the optimal provision of OSH in a perfectly competitive labour market. The plethora of incentives faced by workers and firms in job and insurance markets that determine the ultimate level of OSH are discussed in detail. The extensive empirical evidence from the hedonic wage and stated choice approaches used to assess the value of OSH is reviewed. The causes of inefficiency and inequity in the market for OSH, such as externalities, moral hazard in compensation insurance, systematic biases in individual risk perception/well‐being and labour market segregation are subsequently examined. The implications of government intervention and regulation for tackling the aforementioned inefficiencies in OSH are then considered. Finally, the survey identifies areas of future research interests and suggests indicators and priorities for policy initiatives that can improve the health and safety of workers in modern job markets.     

HAPPINESS AND HEALTH: TWO PARADOXES

Abstract This paper aims to establish systematic relationships between the two rapidly growing research streams on the socio‐economic determinants of happiness and health. Although they have been pursued quite independently by different communities of researchers, empirical evidence points to very similar underlying causal mechanisms. In particular, in both cases per capita income seems to play a major role only up to a very low threshold, beyond which relative income and other relational factors become crucial for happiness and health. On the basis of these structural analogies, we argue that a process of cross‐fertilisation between these two research streams would contribute to their development by clarifying the relationship between happiness, health and their determinants. Finally, we observe that the two literatures have converging policy implications: measures meant to reduce poverty and inequality and invest in social and environmental capital may improve both health and happiness of the individuals.     

TAX COMPETITION AS A CAUSE OF FALLING CORPORATE INCOME TAX RATES: A SURVEY OF EMPIRICAL LITERATURE

Abstract Since the mid 1980s, tax rates on corporate income have declined in most industrialized countries. Tax competition between countries for mobile capital has frequently been mentioned as an explanation for this development. A vast empirical literature dealing with tax competition for mobile capital has emerged. This paper categorizes and summarizes the existing empirical studies on this issue. Particular focus is placed on the isolation of the substantive implications the quantitative study outcomes convey. Given the empirical evidence surveyed, it appears that tax rates indeed decline due to tax competition between countries, and in particular due to competition for profits. In addition to summarizing the substantive implications of the existing empirical literature, the paper addresses the question of whether the existing studies can convincingly isolate tax competition as a driver of falling corporate income tax rates.     

New data collection modes for surveys: a comparative analysis of the influence of survey mode on question-wording effects

New opportunities have recently emerged in survey practice, coupled with a need to make changes, and alternative survey data collection modes such as those based on new technologies (for example, the Web and mobile phones) have become a focus of interest. Studies have considered the biases due to data collection modes and to the wording of questions in questionnaires, but they have rarely dealt with the interaction between the two phenomena. This paper presents the results of a study on the interactions between some of the best-known question-wording effects and three data collection modes: face-to-face, Web-based and SMS-based (Short Text Messaging). The results have highlighted some interesting characteristics of the various modes—innovative ones in particular—and have confirmed the existence of potential interactions between data collection modes and question-wording effects. The findings may have significant implications for the study and practice of surveys and entail that, when surveys are designed, account is taken of specific factors associated with the method used to word the questions in questionnaires.

A quantitative study on mobile services aimed at children and self-regulation in Spain

This paper is part of a research project which highlights the legal and ethical problems of mobile services aimed at children in Spain. The aim of the paper is to offer practical advice on self-regulation in the mobile telephone sector in Spain and to suggest measures that companies could adopt to protect children more effectively. A multivariate statistical analysis was carried out on the results of confidential surveys sent to companies, government agencies and child protection associations in order to establish the key issues to be taken into consideration when drawing up a collective agreement. Children have access to a wide range of services via their mobile phones. We question the suitability of these services and whether the age of the children should be verified before access to these services is allowed. Company policy should include the drawing up of codes of conduct along the lines of the agreement signed by the leading European mobile phone operators.     

THE QUALITY AND EFFICIENCY OF PRIVATE AND PUBLIC EDUCATION: A CASE-STUDY OF URBAN INDIA†

Recent evidence of a substantial link between quality of schooling and individual productivity suggests that, from an economic efficiency perspective, quality aspects of education deserve attention. This paper presents empirical evidence on the relative quality and efficiency of private and government-funded schools in urban India, using data from Uttar Pradesh. The results suggest that standardizing for home background and controlling for sample selectivity greatly reduces the raw average achievement advantage of private school students over public school students, but does not wipe it out. Private schools' standardized achievement advantage (or better quality) is complemented by their lower unit costs to enable them to be more efficient. The results support much of the existing international evidence on the relative efficiency of private and public schools.
