THE ECONOMICS OF ABSENCE: THEORY AND EVIDENCE

Abstract. Worker absenteeism constitutes a significant loss of work-time and therefore has important implications for both household income and firm productivity. Despite this, the economics profession has been somewhat laggard relative to other disciplines in addressing the phenomenon. The situation is, however, changing, with recent years witnessing a mild flurry of activity. The aim of this paper is to maintain, and if possible, enhance this momentum. We do this firstly by developing some basic theoretical ideas which we consider to be central to an economic analysis of absence. In particular, we address the often cited claim that observed absence is unequivocally inefficient. Second, by reviewing some of the key contributions, we attempt to assess where the literature on the economics of absence stands at present, as well as suggesting some potentially fruitful lines of future enquiry.     

OFFSHORING, MULTINATIONALS AND LABOUR MARKET: A REVIEW OF THE EMPIRICAL LITERATURE

Abstract.  This paper reviews the empirical literature on the effects of offshoring and foreign activities of multinational enterprises on developed countries' labour markets. Results suggest that material offshoring worsens wage inequality between skilled and unskilled workers; it also seems to make employment more volatile, by raising the elasticity of labour demand and the risk of job losses. Service offshoring exerts at most small negative effects on total employment, and changes the composition of the workforce in favour of high-skilled white-collar employees. Multinationals tend to substitute domestic and foreign labour in response to changes in relative wages across countries; substitutability is weak, however, and mainly driven by horizontal, market-seeking foreign direct investments.     

MORALITY, ECONOMICS AND THE MARKET IN THE THOUGHT OF BENEDICT XVI

While not uncritical of aspects of modern capitalism, John Paul II's 1991 social encyclical, Centesimus Annus , directed official Catholic teaching towards more explicit affirmation of the moral potential of free markets, exchange and enterprise. Analysis of the pre-pontifical writings of Pope John Paul's successor, Benedict XVI, suggests that an equally nuanced approach to economics and the market from the most authoritative Catholic teaching authority is likely to continue.     

HOW TO MEASURE LABOUR MARKET EFFECTS OF IMMIGRATION: A REVIEW

Abstract.  This paper surveys available empirical evidence on labour market effects of immigration. Many different approaches have been used already to try to find out whether immigration hurts the labour market opportunities of natives. No doubt new approaches will follow in the future as globalization will keep the migration issue on the agenda. This literature review discusses the different approaches concentrating on both the methodology and the results. At the end, it tries to summarize available evidence.     

CHILD LABOUR: A REVIEW OF RECENT THEORY AND EVIDENCE WITH POLICY IMPLICATIONS

In recent years, a growing number of authors have turned their attention to the question of why children work. The purpose of this paper is to review some of the more recent theoretical and empirical research into the topic of child labour, and to illustrate the fact that no one factor on its own can account for the phenomenon of child labour. Therefore, policies aimed at eradicating child labour will need to address the broad range of underlying factors that contribute to the incidence of child labour, such as poverty, market imperfections and access to education.     

A SURVEY OF THE ECONOMICS OF PATENT SYSTEMS AND PROCEDURES

The last several decades have seen increases in patenting activity worldwide, as well as growing issues related to patent quality. In response to these quality issues a recent patent literature has emerged, that investigates the behavior and incentives of patent examiners, applicants, and third parties. In this paper, we provide an overview of patent procedures, patent systems and a survey of the new economic literature on patent systems. Both theoretical and empirical papers are considered. Policy implications coming from this literature are presented.     

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.     

LABOUR PRODUCTIVITY CHANGES AND WORKING TIME: THE CASE OF GREECE

In terms of the annual hours worked per employee, Greece ranks first among EU-15 countries and second among OECD countries. In this context, the austerity measures it adopted (as suggested by the EU and IMF) imply, among other things, a reduction in the over-hours. If such reductions were not to be accompanied by increases in labour productivity, output would be reduced considerably. This paper therefore addresses the question: “What change in sectoral labour productivity levels would have been required to deliver the actual change in final demands in Greece between 1995 and 2005, if working hours in each sector had been reduced to their EU averages?” In this framework, we develop a methodology for calculating labour productivity change by sector of economic activity in an input–output context. Next, we apply it to the Greek economy for the time period 1995–2005, the most recent period for which the required data are available. We find that the required productivity changes are the most substantial for the hotels and restaurants sector, followed by machinery manufacturing and the trade sectors.     

BRIDGING TRADE THEORY AND LABOUR ECONOMETRICS: THE EFFECTS OF INTERNATIONAL MIGRATION*

Abstract This paper surveys current theoretical and empirical research on international migration with a particular emphasis on the links between trade theory and labour empirics.     

DEMAND,CUSTOMER BASE‐LINE AND DEMAND RESPONSE IN THE ELECTRICITY MARKET: A SURVEY

The increasing use of demand‐side management, as a tool to reliably meet electricity demands at peak time, has stimulated interest among researchers, consumers and producer organiza‐tions, managers, regulators and policymakers. This research reviews the growing literature on models which are used to study demand, customer base‐line (CBL) and demand response in the electricity market. After characterizing the general demand models, the CBL, based on which the demand response models are studied, is reviewed. Given the experience gained from the review and existing conditions, the study combines an appropriate model for each case for a possible application to the electricity market; moreover, it discusses the implications of the results. In the literature, these aspects are studied independently. The main contribution of this survey is attributed to the treatment of the three issues as sequentially interdependent. The review is expected to enhance the understanding of the demand, CBL and demand response in the electricity market and their relationships. The objective is conducted through a combination of demand and supply side managements in order to reduce demand through different demand response programs during peak times. This enables electricity suppliers to save costly electricity generation and at the same time reduce energy vulnerability.     

CONTRACTS,ENTREPRENEURS, MARKET CREATION AND JUDGEMENT: THE CONTEMPORARY MAINSTREAM THEORY OF THE FIRM IN PERSPECTIVE

This survey gives an overview of the theory of the firm as it is formulated within the contemporary ‘mainstream’ of economics. Two groupings of theories are briefly discussed: principal–agent and incomplete contract models. Next, three of the most recent contributions regarding firms are considered. The reference point approach is looked at first followed by a discussion of Spulber's book The Theory of the Firm. Last, we consider the entrepreneurial judgement perspective.     

THE IMPACT OF LABOR MARKET REGULATION ON EMPLOYMENT IN LOW‐INCOME COUNTRIES: A META‐ANALYSIS

Controversy over labor market policy often centers on achieving a balance between preventing worker exploitation, and avoiding loss of productivity or employment through excessive regulation. Although the literature documenting the impact of labor market regulation on employment is extensive, there is a dearth of evidence on the impact of such policies in low‐income countries (LICs). Since it is easier for workers, especially women, to slip into the informal sector in LICs, regulations are likely to have stronger impacts on formal employment in these countries (but lower impacts on unemployment). We systematically reviewed available research from countries that are, or were until recently, LICs. Most studies document that more stringent labor regulations are associated with lower formal sector employment and higher informal sector employment. We also conducted a metaregression analysis of the impact of minimum wages on formal and informal employment. After controlling for publication bias, higher minimum wages are associated with lower formal employment and a higher share of informal workers.     

OWNERSHIP, CONTROL, FINANCIAL STRUCTURE AND THE PERFORMANCE OF FIRMS

Abstract. The notion that the separation of ownership from control may create a divergence of interests between managers and shareholders has led to a large number of studies which investigate the influence of ownership structures upon a firm's financial structure and its performance. The purpose of this paper is to review and critically evaluate the literature that empirically analyses the effects of ownership and control structures on both the financial structure and the performance of the firm. In addition, further consideration is given to the dynamic relationships between ownership, control, financing and firm performance.     

THE TERM STRUCTURE OF INTEREST RATES: EVIDENCE AND THEORY

Abstract. The term structure of interest rates is an old topic. Over the years, both the hypotheses debated and the research techniques used have changed considerably. Two fairly recent developments which distinguish current research are the widespread adoption of rational expectations and the integration of the term structure with the general theory of asset pricing. This survey reviews previous work from this perspective. The main objective is to catalogue available evidence about term premia and to interpret this evidence in light of alternative models of term premia determination.     

STOCK‐FLOW INTERACTIONS,DISEQUILIBRIUM MACROECONOMICS AND THE ROLE OF ECONOMIC POLICY

This paper presents the ‘KMGT’ (Keynes–Metzler–Goodwin–Tobin) portfolio model and studies its stability properties. The approach to macrodynamic modelling taken here extends the KMG model of Chiarella and Flaschel (2000) , focusing in particular on the incorporation of financial markets and policy issues. The original KMG model considered three asset markets (equities, bonds and money) but depicted them in a rudimentary way so that they had little influence on the real side of the model. The only financial market influencing the real side of the economy was the money market (via an LM curve theory of interest). Here Tobin's portfolio choice theory models the demand for each asset in such a way that the total amount of assets that households want to hold equals their net wealth, which is a stock constraint attached to portfolio choice. There is also a flow constraint, that the net amount of assets accumulated (liabilities issued) by one sector must equal its net savings (expenditures). The Tobinian macroeconomic portfolio approach characterizes the potential for financial market instability, focusing on the interconnectedness of all three markets. The paper goes on to study the potential for labour market and fiscal policies to stabilize unstable macroeconomies.     

POPULATION AGE STRUCTURE,SAVING, CAPITAL FLOWS AND THE REAL EXCHANGE RATE: A SURVEY OF THE LITERATURE

Abstract This paper surveys the existing literature on the effects of population age structure on saving, capital flows and the real exchange rate. We build on previous surveys of age structure and saving behaviour by including extensive discussion of international linkages, specifically the impact on capital flows and real exchange rates. We also point to unresolved issues that need to be addressed given that population aging has serious policy implications in the developed economies these days.
