Empirical Studies of Self‐Employment

This paper presents a review of empirical studies of self‐employment for the Australian, Canadian, Dutch, UK and US labour markets. Both cross‐sectional and longitudinal studies are analysed. Analyses using cross‐sectional data examine the propensity to be self‐employed at any one point in time, whereas longitudinal studies focus on the transition into self‐employment from wage/salary employment and the survival rate in this state over time. Various hypotheses advanced in the economics and sociology literatures on self‐employment are tested. These include the relationship between managerial ability and the propensity to be self‐employed and the impact of financial constraints on entry into self‐employment stressed in economic models of entrepreneurship, and the relationships between self‐employment choice and the nature of the work and group characteristics (e.g., ethnic enclaves) stressed in sociological models of entrepreneurship. The evidence shows that self‐employment outcomes are significantly affected by factors such as individual abilities, family background, occupational status, liquidity constraints and ethnic enclaves.     

Non‐Mandatory Approaches to Environmental Protection

The approach to environmental protection has been evolving from a regulation‐driven, adversarial 'government‐push' approach to a more proactive approach involving voluntary and often 'business‐led' initiatives to self‐regulate their environmental performance. This has been accompanied by increasing provision of environmental information about firms and products to enlist market forces and communities in creating a demand for corporate environmental self‐regulation by signaling their preferences for environmentally friendly firms. This paper provides an overview of the non‐mandatory approaches being used for environmental protection and surveys the existing theoretical literature analyzing the economic efficiency of such approaches relative to mandatory approaches. It also discusses empirical findings on the factors motivating self‐regulation by firms and its implications for their economic and environmental performance. It examines the existing evidence on the extent to which information disclosure is effective in generating pressures from investors and communities on firms to improve their environmental performance.     

A Meta‐Analysis of β‐Convergence: the Legendary 2%

Abstract.  The topic of convergence is at the heart of a wide‐ranging debate in the growth literature, and empirical studies of convergence differ widely in their theoretical backgrounds, empirical specifications, and in their treatment of cross‐sectional heterogeneity. Despite these differences, a rate of convergence of about 2% has been found under a variety of different conditions, resulting in the widespread belief that the rate of convergence is a natural constant. We use meta‐analysis to investigate whether there is substance to the 'myth' of the 2% convergence rate and to assess several unresolved issues of interpretation and estimation. Our data set contains approximately 600 estimates taken from a random sample of empirical growth studies published in peer‐reviewed journals. The results indicate that it is misleading to speak of a natural convergence rate since estimates of different growth regressions come from different populations, and we find that correcting for the bias resulting from unobserved heterogeneity in technology levels leads to higher estimates of the rate of convergence. We also find that correcting for endogeneity of the explanatory variables has a substantial effect on the estimates and that measures of financial and fiscal development are important determinants of long‐run differences in per capita income levels. We show that although the odds of a study being published is not uniform for studies with different p ‐values, publication bias has no significant effect on the conclusions of the analysis.     

Charity registration and reporting: a cross-jurisdictional and theoretical analysis of regulatory impact

Governments increasingly regulate charities to restrict the number of organizations claiming taxation exemptions, reduce charities’ ability to abuse state support, and detect and deter fraud. Public interest theory arguments suggest that regulation could increase philanthropy through enhancing public trust and confidence in charities. Nevertheless, public choice theory argues that regulators seek to maximize political returns, ‘manage’ charity-government relationships, and reduce potential regulatory capture.

We analyse charity regulatory regimes using these two regulatory theories and the relative costs and benefits of different regulatory regimes. Heeding these should reduce regulatory inefficiency and balance accountability and transparency demands against benefits charities receive from regulation.     

Market‐oriented institutions and policies and economic growth: A critical survey

Abstract.  This paper surveys recent evidence suggesting that market‐oriented institutions and policies are strongly related to economic growth, focusing on studies using the economic freedom (EF) indicator of the Fraser Institute. This index is critically discussed. Also various serious shortcomings of empirical studies using this index are identified. Nevertheless, there are strong indications that liberalization, i.e. an increase in the EF index, stimulates economic growth. This paper also reviews studies on the determinants of EF. Political liberalization is often found to enhance economic liberalization, whereas there is less evidence for causality running in the other direction.     

Meta‐Regression Analysis: A Quantitative Method of Literature Surveys

Abstract.  Pedagogically, literature reviews are instrumental. They summarize the large literature written on a particular topic, give coherence to the complex, often disparate, views expressed about an issue, and serve as a springboard for new ideas. However, literature surveys rarely establish anything approximating unanimous consensus. Ironically, this is just as true for the empirical economic literature. To harmonize this dissonance, we offer a quantitative methodology for reviewing the empirical economic literature. Meta‐regression analysis (MRA) is the regression analysis of regression analyses. MRA tends to objectify the review process. It studies the processes that produce empirical economic results as though they were any other social scientific phenomenon. MRA provides a framework for replication and offers a sensitivity analysis for model specification. In this brief essay, we propose a new method of reviewing economic literature, MRA, and discuss its potential.     

Cost‐ and Income‐based Measures of Human Capital

Human capital is increasingly believed to play an important role in the growth process, however, adequately measuring its stock remains controversial. In this paper three general approaches to measurement are identified; cost‐based, income‐based and educational stock‐based. This survey focuses on the first two approaches and provides a critical review of the theories and their applications to data from a range of countries. Particular emphasis is placed upon the work of Jorgenson and Fraumeni (1989, 1992) and some new results for New Zealand based upon their approach are also presented.     

Models of Quality‐Adjusted Life Years when Health Varies Over Time: Survey and Analysis

Abstract.  Quality‐adjusted life year (QALY) models are widely used for economic evaluation in the health care sector. In the first part of the paper, we establish an overview of QALY models where health varies over time and provide a theoretical analysis of model identification and parameter estimation from time trade‐off (TTO) and standard gamble (SG) scores. We investigate deterministic and probabilistic models and consider five different families of discounting functions in all. The second part of the paper discusses four issues recurrently debated in the literature. This discussion includes questioning the SG method as the gold standard for estimation of the health state index, re‐examining the role of the constant‐proportional trade‐off condition, revisiting the problem of double discounting of QALYs, and suggesting that it is not a matter of choosing between TTO and SG procedures as the combination of these two can be used to disentangle risk aversion from discounting. We find that caution must be taken when drawing conclusions from models with chronic health states to situations where health varies over time. One notable difference is that in the former case, risk aversion may be indistinguishable from discounting.     

The Desirability of In‐kind Transfers in the Presence of Distortionary Taxes

A standard argument in welfare economics maintains that private goods should not be publicly provided, because cash transfers are always superior to in‐kind transfers. However, this conclusion does not hold in second best economies. A strong case for the desirability of in‐kind transfer in the presence of distortionary taxes has been made in various recent contributions. Here, we survey the arguments provided in these papers, using a common theoretical framework which enables us to present more clearly the similarities and the differences among the various papers. The use of a common formal model helps us to show how the rationale for public provision of private goods is sensitive to the form of the tax system. It also helps us to provide an explanation why mandatory and non‐mandatory in‐kind transfer schemes have the same effects on social welfare. Finally, we offer some considerations on the relevance of the theory of in‐kind transfers for policy action. JEL Classification Number: H42

A Meta‐Analysis of the International Gender Wage Gap

Abstract.  Since the early 1970s, a number of authors have calculated gender wage differentials between women and men of equal productivity. This meta‐study provides a new quantitative review of this vast amount of empirical literature on gender wage differentials as it concerns not only differences in methodology, data, and time periods, but also different countries. We place particular emphasis on a proper consideration of the quality of the underlying study which is done by a weighting with quality indicators. The results show that data restrictions – i.e. the limitation of the analysis to new entrants, never‐marrieds, or one narrow occupation only – have the biggest impact on the resulting gender wage gap. Moreover, we are able to show what effect a misspecification of the underlying wage equation – like the frequent use of potential experience – has on the calculated gender wage gap. Over time, raw wage differentials worldwide have fallen substantially; however, most of this decrease is due to better labor market endowments of females.     

Non‐linear Dynamics in the Infinite Time Horizon Model

Using results from the theory of non‐linear dynamical systems, it has been shown that optimal growth theory can provide new explanations for business cycles and for international differences in growth and development. The present survey concentrates on this aspect of optimal growth theory, that is on the possibility of fluctuations and non‐uniqueness in models of optimal capital accumulation. It is a selective survey on non‐linear dynamics in infinite time horizon models of optimal growth.     

The Long‐Run implications of Growth Theories

This paper draws attention to some possible misunderstandings concerning the place of long‐run outcomes in growth theory. It argues that the traditional emphasis on these outcomes is often misguided. As a result of this emphasis, too much attention is paid to the role of knife‐edge assumptions, and researchers may be led to interpretations of the evidence, or models of the growth process, that are not wholly sensible.     

The Theory of Socially Embedded Games: Applications and Extensions to Open and Closed Games

An earlier article, drawing on the mathematical theory of rules and rule complexes, extends and generalizes game theory (GGT). The theory has been used to conceptualize and analyze diverse social relationships, roles, and games as particular types of rule complexes.For instance, a social role, as a major basis of a parent's action in a game, consists of at least four key components – which are mathematical objects – in the determination of action: value complex, model of reality (including beliefs and knowledge bases), a repertoire of acts, routines, programs, and strategies, and modality, a role-specific algorithm for determining or generating action in game settings. This article applies and extends GGT in analyses of a market bargaining game (a type of open game) and of the classical game of prisoners' dilemma (a type of closed game). The applications show the concrete effects of social embeddedness on game structuring, game interaction patterns and outcomes, and social equilibria.     

A study on the influence of eWOM using content analysis: how do comments on value for money,product sophistication and experiential feeling affect our choices?

The influence of electronic word of mouth (eWOM) has been heavily investigated in relation to online ratings. However, only a few studies examined the content of eWOM. From the perspective of the consideration sets model, consumers formulate an awareness set, a consideration set and a choice set before making a purchase. We argue that the formulation of these sets is influenced by eWOM based on its volume, valance and content relating to product attributes such as value for money, product sophistication and experiential feeling. In this study, the content of posts relating to Shure professional earphones in the online forum Mingo (www.mingo-hmw.com/forum) was captured and annotated. During the data collection period, Mingo was the sole online forum relating to professional earphones. Without much interference from other online forums, the circumstances of this study closely approximate a laboratory setting. In addition, we collected the actual sales, marketing costs, fault rates and number of retail stores selling the Shure professional earphones for 126 weeks. Our findings show that the weekly volume of posts, their relative number of positive (negative) comments, especially regarding value for money and sound quality, and those posts from the earlier week impinged strongly on weekly sales of Shure products. From the regression models, the explained variance in sales jumps from 0.236 to 0.732 due to the influence of eWOM.     

The Effectiveness of Anti‐Smoking Legislation: A Review

Abstract.  This survey focuses on government efforts to curb the use of undesirable goods, notably tobacco products. We synthesize the economics literature and examine the effectiveness of government curbs on tobacco consumption through non‐price controls (such as bans on cigarette advertising, health warnings, and workplace smoking bans) and price measures (or higher prices through higher taxes). This literature review is unique in that we do not merely aim to provide a summary of the literature. Rather, our main focus is to draw conclusions from the literature regarding the effectiveness of alternate policy measures across countries in checking smoking and to provide directions/suggestions for extending the scope of government intervention to other tobacco products.     

Decision-Making Patterns in Multilevel Governance: The contribution of informal and procedural interactions to significant multilevel decisions

To come to decisions in a multilevel setting, informal as well as procedural interactions are of importance. In this paper, we explored in a case study the decision-making patterns between informal interactions and procedural interactions, and the significance of the decisions resulting from different patterns.

We discovered five patterns of multilevel decision-making: top-down processes, bottom-up processes, collaborative decision-making, synchronization by procedures, and synchronization by interactions. We conclude that these patterns do have different results. Top-down and bottom-up processes often result in mutually extinguishing decisions, whereas the other patterns can result into decisions that matter, depending on the relationships between levels.     

An Exegesis on Currency and Banking Crises

Abstract.  This paper reviews the literature on currency and banking crises. Currency and banking crises are characterized according to some standards in the literature and their historical record summarized. The development of the literature from first through fourth‐generation, or so‐called 'institutional' models is reviewed. A digression on institutions is provided along with some sidebars on the development of the literature on institutions as it relates to economic growth. The empirical research on third‐generation (or twin crises) models and on institutional models of currency and banking crises, which are so far scarce, is covered too. A summary of the main policy issues for dealing with financial crises is presented. The paper closes with an emphasis on institutions and a call for more research directed at institutions and their role in the financial system.
