TECHNOLOGICAL INNOVATION AND EMPLOYMENT IN DERIVED LABOUR DEMAND MODELS: A HIERARCHICAL META‐REGRESSION ANALYSIS

The effect of technological innovation on employment is of major concern for workers and their unions, policy makers and academic researchers. We meta‐analyse 570 estimates from 35 primary studies that estimate a derived labour demand model. We contribute to existing attempts at evidence synthesis by addressing the risks of selection bias and that of data dependence in observational studies. Our findings indicate that: (i) hierarchical meta‐regression models are sufficiently versatile for addressing both selection bias and data dependence in observational data; (ii) innovation's effect on employment is positive but small and highly heterogeneous; (iii) only a small part of residual heterogeneity is explained by moderating factors; (iv) selection bias tends to reflect preference for upholding prevalent hypotheses on the employment effects of process and product innovations; (v) country‐specific effect‐size estimates are related to labour market and product market regulation in six OECD countries in a U‐shaped fashion; and (vi) OLS estimates reflect upward bias whereas those based on time‐differenced or within estimators reflect a downward bias. Our findings point out to a range of data quality and modelling issues that should be addressed in future research.     

THE NORMALIZED CES PRODUCTION FUNCTION: THEORY AND EMPIRICS

Abstract The elasticity of substitution between capital and labor and, in turn, the direction of technical change are critical parameters in many fields of economics. Until recently, though, the application of production functions with specifically non‐unitary substitution elasticities (i.e., non‐Cobb–Douglas) was hampered by empirical and theoretical uncertainties. As recently revealed, ‘normalization’ of production‐technology systems holds out the promise of resolving many of those uncertainties. We survey and assess the intrinsic links between production (as conceptualized in a production function), factor substitution (as made most explicit in Constant Elasticity of Substitution functions) and normalization (defined by the fixing of baseline values for relevant variables). First, we recall how the normalized Constant Elasticity of Substitution function came into existence and what normalization implies for its formal properties. Then we deal with the key role of normalization in recent advances in the theory of business cycles and of economic growth. Next, we discuss the benefits normalization brings for empirical estimation and empirical growth research. Finally, we identify promising areas of future research.     

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.     

PRICE DISCRIMINATION: A SURVEY OF THE THEORY

Abstract. The purpose of this survey is twofold. First, it introduces the reader to recent developments in the theory of price discrimination. Simultaneously, the exposition aims at being self-contained and accessible to the non-specialist reader. The paper is structured around Pigou's distinction between perfect, second-degree and third-degree price discrimination.     

THE FINANCIAL DEVELOPMENT AND GROWTH NEXUS: A META‐ANALYSIS

We conduct a meta‐analysis of the literature of financial development and economic growth. We cover a large number of empirical studies and estimations that have been published in journal articles. We measure the degree of heterogeneity and identify the causes of the observed differentiation. Among the most significant factors behind this heterogeneity is the choice of financial‐variable proxies, the kind of data used as well as whether a study takes into account the issue of endogeneity. Our results suggest that the empirical literature on the finance–growth nexus is not free from publication bias. Also, a genuine positive effect exists between financial development and economic growth.     

MAPPING THE EVOLUTION OF ENERGY‐GROWTH NEXUS: SYNERGIES AND TRADE‐OFFS

The study explores the intellectual structure, development and evolution of energy crisis and economic growth research through bibliometric analysis of research articles on energy‐growth nexus from 2000 to 2017 by using Citespace where Gephi is used to analyse the authors collaboration. The analysis incorporates 27,152 references cited by 344 authors, in 1165 articles and from 330 journals. The results of study quantitatively present the most cited articles, authors, countries, institutions and intellectual structure with data visualization in the knowledge domain of energy‐growth nexus. The study categorizes the major research areas in energy‐growth nexus research as carbon dioxide emission, electricity consumption, heterogeneous Panel, real income, renewable energy and financial development. The study discusses emerging trends which provide the future research fronts and intellectual development within the framework of energy‐growth nexus.     

THE BENEFITS AND COSTS OF MONETARY UNION IN SOUTHERN AFRICA: A CRITICAL SURVEY OF THE LITERATURE

Abstract.  With the 14 members of the Southern African Development Community (SADC) having set the objective of adopting a common currency for the year 2018, an expanding empirical literature has emerged evaluating the benefits and costs of a common-currency area in Southern Africa. This paper reviews that literature, focusing on two categories of studies: (1) those that assume that a country's characteristics are invariant to the adoption of a common currency and (2) those that assume that a monetary union alters an economy's structure, resulting in trade creation and credibility gains. The literature reviewed suggests that a relatively small group of countries, typically including South Africa, satisfies the criteria necessary for monetary unification. The literature also suggests that, in a monetary union comprising all SADC countries and a regional central bank that sets monetary policy to reflect the average economic conditions (e.g. fiscal balances) in the region, the potential losses (i.e. higher inflation) from giving up an existing credible national central bank, a relevant consideration for South Africa, could outweigh any potential benefits of trade creation resulting from a common currency.     

A SURVEY OF THE EVOLUTION OF QUEUEING THEORY

The evolution of queueing theory is sketched from its origin in Teletraffic, via its growth to maturity as a mathematical discipline in Operations Research, to its present position as an indispensable tool in the performance analysis of complex computer—and communication networks. The Dutch postwar contributions to this evolution receive some special attention, on the occasion of the celebration of the Dutch Society for Statistics and 'Operations Research' fourth decennium.     

THE RISE AND DECLINE OF ECONOMIC POLICY AS AN AUTONOMOUS DISCIPLINE: A CRITICAL SURVEY

After Adam Smith's statement of market virtues, the process of gestation of economic policy as a rational set of rules for public agenda has been rather slow. Until not so long ago, economic policy as a discipline was often confined to prescribing practical rules intended to explain technical procedures of government intervention. Economic policy– as a coherent and to some extent autonomous discipline–only emerged in the late 1950s in Scandinavia, the Netherlands and Italy, when solid foundations indicating not only microeconomic but also macroeconomic market failures and a theory about the conditions for policy effectiveness and design were consistently developed. This paper intends to explain the reasons for the emergence of the discipline, the circumstances that favoured its diffusion, the reasons for its apparent setback and some factors that could facilitate its diffusion in the next years     

REAL BUSINESS CYCLE MODELS OF THE GREAT DEPRESSION: A CRITICAL SURVEY

Abstract.  Recent years have witnessed a revival of interest in the Great Depression of the 1930s. Among the differing new interpretations, the real business cycle (RBC) approach is particularly significant. It represents an outstanding methodological innovation in trying to cast the Great Depression within an 'equilibrium' framework. This paper critically reviews the RBC interpretation of the Great Depression, clarifying its theoretical and methodological foundations, and paving the way for future assessments of its validity.     

PUBLIC R&D POLICIES AND PRIVATE R&D INVESTMENT: A SURVEY OF THE EMPIRICAL EVIDENCE

The importance of R&D investment in explaining economic growth is well documented in the literature. Policies by modern governments increasingly recognise the benefits of supporting R&D investment. Government funding has, however, become an increasingly scarce resource in times of financial crisis and economic austerity. Hence, it is important that available funds are used and targeted effectively. This paper offers the first systematic review and critical discussion of what the R&D literature has to say currently about the effectiveness of major public R&D policies in increasing private R&D investment. Public policies are considered within three categories, R&D tax credits and direct subsidies, support of the university research system and the formation of high‐skilled human capital, and support of formal R&D cooperations across a variety of institutions. Crucially, the large body of more recent literature observes a shift away from the earlier findings that public subsidies often crowd‐out private R&D to finding that subsidies typically stimulate private R&D. Tax credits are also much more unanimously than previously found to have positive effects. University research, high‐skilled human capital, and R&D cooperation also typically increase private R&D. Recent work indicates that accounting for non‐linearities is one area of research that may refine existing results.     

THE ECONOMIC IMPACTS OF VOLUNTARY ENVIRONMENTAL PERFORMANCE OF FIRMS: A CRITICAL REVIEW

Abstract.  New trends in studies on the governance of natural assets include substantial consideration of the role of voluntary initiatives. A traditional economic view states that there is a trade-off between being green and being competitive. According to that view, no voluntary environmental action is expected to occur. To undertake an in-depth analysis of the scope for voluntary action, this paper reviews empirical literature that analyzes the relationship between manufacturing firms' environmental initiatives or performance and economic results. This review moves beyond the general test of the 'pay to be green' hypothesis, preferring instead to systematize empirical results in more specific research questions. Empirical findings of the reviewed literature generally support that there is no penalty for being green. In addition, the typology of firms, the methods utilized for implementing environmental initiatives, the intensity of abatement efforts and stockholders' valuation of green firms have all been shown to have a sizeable influence on the actual economic results of environmental action or management. Consequently, the findings of this paper challenge the traditional strategic theory that predicts widespread free-riding; it holds major implications for environmental policy-making and environmental business decisions.     

ECONOMIC ANALYSIS OF KNOWLEDGE: THE HISTORY OF THOUGHT AND THE CENTRAL THEMES

Following the development of knowledge economies, there has been a rapid expansion of economic analysis of knowledge, both in the context of technological knowledge in particular and decision theory in general. This paper surveys this literature by identifying the main themes and contributions, and outlines the future prospects of the discipline. The wide scope of knowledge‐related questions in terms of applicability and alternative approaches has led to the fragmentation of research. Nonetheless, one can identify an enduring quest for analyzing various aspects of the generation, dissemination and use of knowledge in the economy.     

GAME THEORY AND PORT ECONOMICS: A SURVEY OF RECENT RESEARCH

The last decade has seen a significant upsurge of studies seeking to examine the impacts of port agents’ strategic decisions. The outcome has been a wide range of results and conclusions. The aim of this work is to provide a review of this recent research in the port industry that uses strategic interaction approaches from industrial organization and game theory. The paper concentrates on five topics: ownership, relationship between ports and their hinterlands, port authorities and port operators’ relations, capacity investment decisions, and port specialization. We present the objectives, methodologies and results of the papers reviewed, with special emphasis on how models are developed. The results are not always consistent between the works analyzed. On the one hand, this could be due to the complexity of the port industry and the high number of agents that intervene. Researchers need to simplify reality to build their models by imposing restrictive assumptions. On the other hand, results could be very sensitive to the techniques used or to the differences on the port environment of the countries of study. However, some conclusions can be extracted and they present a good starting point to develop more sophisticated models. Finally, we also propose avenues for future research.     

THE DECADES‐LONG DISPUTE OVER SCALE EFFECTS IN THE THEORY OF ECONOMIC GROWTH

The so‐called “new growth theory” is characterized by the now Nobel Prize winning insight that ideas are a nonrival input to and output from endogenous investment in innovation. Nonrivalry implies increasing returns to scale, but this also unintentionally creates an empirically disputed scale effect that a growing population implies an ever‐increasing growth rate. Empirical evidence supports fully‐endogenous growth without scale effects, but theoretical issues sustain the decades‐long dispute over exactly how to negate the scale effect. This article surveys theoretical approaches to resolving the scale effect and shows how four generations of endogenous growth theory are defined by the maturing of modeling techniques for constraining increasing returns. The synthesis suggests that the dispute over scale effects is really a narrative about how the powerful application of increasing returns has followed a standard theoretical development pattern. This implies that a fourth generation is now emerging that negates the scale effect while retaining fully‐endogenous growth without relying on assumptions of linearity. Instead, the market response to excessive increasing returns to innovation constrains explosive growth by expanding the market, rather than by a linear assumption. This latest class of endogenous growth models may be the final chapter to resolving the long‐running dispute.     

REAL‐TIME DATA AND FISCAL POLICY ANALYSIS: A SURVEY OF THE LITERATURE

This paper surveys the empirical research on fiscal policy analysis based on real‐time data. This literature can be broadly divided into four groups that focus on: (1) the statistical properties of revisions in fiscal data; (2) the political and institutional determinants of projection errors by governments; (3) the reaction of fiscal policies to the business cycle and (4) the use of real‐time fiscal data in structural vector autoregression (VAR) models. It emerges that, first, fiscal revisions are large and initial releases are biased estimates of final values. Secondly, strong fiscal rules and institutions lead to more accurate releases of fiscal data and smaller deviations of fiscal outcomes from government plans. Thirdly, the cyclical stance of fiscal policies is estimated to be more ‘counter‐cyclical’ when real‐time data are used instead of ex post data. Fourthly, real‐time data can be useful for the identification of fiscal shocks. Finally, it is shown that existing real‐time fiscal data sets cover only a limited number of countries and variables. For example, real‐time data for developing countries are generally unavailable. In addition, real‐time data on European countries are often missing, especially with respect to government revenues and expenditures. Therefore, more work is needed in this field.     

THE DEBATE ABOUT THE REVIVED BRETTON‐WOODS REGIME: A SURVEY AND EXTENSION OF THE LITERATURE

This paper surveys the literature dealing with the thesis put forward by Dooley, Folkerts‐Landau and Garber (DFG) that the present constellation of global exchange‐rate arrangements constitutes a revived Bretton‐Woods regime. DFG also argue that the revived regime will be sustainable, despite its large global imbalances. While much of the literature generated by DFG's thesis points to specific differences between the earlier regime and revived regime that render the latter unstable, we argue that an underlying similarity between the two regimes renders the revived regime unstable. Specifically, to the extent that the present system constitutes a revived Bretton‐Woods system, it is vulnerable to the same set of destabilizing forces – including asset‐price bubbles and global financial crises – that marked the latter years of the earlier regime, leading to its breakdown. We extend the Markov switching model to examine the relation between global liquidity and commodity prices. We find an evidence of commodity‐price bubbles in both the latter stages of the earlier Bretton‐Woods regime and the revived regime.     

CORPORATE GOVERNANCE AND INNOVATION: A SURVEY

Abstract The traditional economics of innovation, inspired by Schumpeter and more recent advances on his work, seem unable to explain why firms with similar external conditions may show greatly different performance in innovation. Contrastingly, the literature on corporate governance provides some useful insights for understanding corporate innovation activity, to the extent that such literature examines the economic effects of different modes of coordination between firm members. The process through which individuals integrate their human and physical resources within the firm is central to the dynamics of corporate innovation. This paper provides the first survey of the literature on this issue. We start by discussing how various theoretical approaches to the analysis of the firm deal with technological innovation. We then describe three main channels – corporate ownership, corporate finance and labour – through which a system of corporate governance shapes a firm's innovation activity. Finally, we examine the relationship between country‐level institutional settings, national patterns of corporate governance and the aggregate innovation activity of corporations. We conclude by suggesting that future research should focus more deeply on the interrelation between the various dimensions of corporate governance and on their joint effect on firm innovation.
