THE ECONOMICS OF NETWORKS: A SURVEY OF THE EMPIRICAL LITERATURE

Abstract.  Network effects, the increase in value of consuming a product if many other consumers use the same product, are a feature of many markets and in particular of many high-technology products. This paper surveys the burgeoning empirical literature that has developed especially during the last years. After theoretical work dominated the earlier years of research in this area, newer research has combined theoretical models with empirical studies and applied work with direct implications for public policy, marketing and company strategies. Furthermore, insights from the study of social networks have been applied to analyse how consumers interact with each other. The paper argues that a closer analysis of the network structure of consumer interaction promises fruitful future research avenues and advances in our understanding of how network effects operate.     

THE ECONOMICS OF MOVIES: A LITERATURE SURVEY

Abstract The film industry provides a myriad of interesting problems for economic contemplation. From the initial concept of an idea through production, distribution and finally exhibition there are many aspects to the film project and the film industry that present new and interesting puzzles worthy of investigation. Add to this the high level of data availability, and it is little wonder that an increasing number of researchers are being attracted to this industry. To date, however, there are no comprehensive surveys on the contribution of economists to this literature. This paper attempts to fill this void and unify what is known about the industry. It also identifies and discusses potential areas for new 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.     

THE ECONOMICS OF FISCAL DECENTRALIZATION

Abstract There is no complete overview or discussion of the literature of the economics of federalism and fiscal decentralization, even though scholarly interest in the topic has been increasing significantly over recent years. This paper provides a general, brief but comprehensive overview of the main insights from the literature on fiscal federalism and decentralization. In doing so, literature on fiscal federalism and decentralization is grouped into two main approaches: ‘first generation approach’ and ‘an emerging second generation approach’. The discussion generally covers the two notions of fiscal decentralization: ‘fiscal autonomy’ and ‘fiscal importance’ of subnational governments as the background of the most recently developed index of fiscal decentralization in Vo. The relevance of this discussion to any further development of a fiscal decentralization index is briefly noted.     

THE ECONOMICS OF CORPORATE SOCIAL RESPONSIBILITY: A FIRM‐LEVEL PERSPECTIVE SURVEY

This paper analyzes the economics of Corporate Social Responsibility (CSR), as a private response to market imperfections in order to satisfy social preferences. Depending on whether they affect regulation, competition or contracts, market imperfections driving CSR decisions are classified in three categories: public goods and bads and altruism; imperfect competition; and incomplete contracts. We successively present these drivers of CSR decisions and highlight the nature of incentives (external or internal) at work and the testable (and tested) hypotheses in the reviewed studies. We finally review the link between CSR and financial performance, as well as between CSR and social and environmental performance. A twofold discrepancy appears in the literature, opening future research paths: a disconnection between our understanding of CSR drivers and CSR impacts; and a knowledge gap between CSR financial and social consequences, the latter having received little attention.     

VARIATIONS ON THE THEME OF CONNINGa IN MATHEMATICAL ECONOMICS

Abstract The mathematization of economics is almost exclusively in terms of the mathematics of real analysis which, in turn, is founded on set theory (and the axiom of choice) and orthodox mathematical logic. In this paper I try to point out that this kind of mathematization is replete with economic infelicities. The attempt to extract these infelicities is in terms of three main examples and one general discussion: dynamics, policy and rational expectations and learning are the examples; a game theory without ‘subjectivism’, based on the axiom of determinateness, is discussed in general terms. The focus is on the role and reliance of standard fixed‐point theorems in orthodox mathematical economics.     

DELEGATED PORTFOLIO MANAGEMENT: A SURVEY OF THE THEORETICAL LITERATURE

Abstract.  This paper provides a selective review of the theoretical literature on delegated portfolio management as a principal–agent relationship. The main focus of the paper is to review the analytical issues raised by the peculiar nature of the delegated portfolio management relationship within the broader class of principal–agent models. In particular, the paper discusses the performance of linear versus nonlinear compensation contracts in a single-period setting, the possible effects of limited liability of portfolio managers, the role of reputational concerns in a multiperiod framework, and the incentives to noise trading. In addition, the paper deals with some general equilibrium dimensions and asset pricing implications of delegated portfolio management. The paper also suggests some directions for future research.     

EXCHANGE RATE TARGET ZONES: A SURVEY OF THE LITERATURE

This work selectively reviews the literature on exchange rate target zones and their theoretical and empirical methodologies and examines whether they can be used to clarify to what extent this type of exchange rate regime could contribute to greater exchange rate stability. We discuss the main contributions of the first and second generations of exchange rate target zone models. In an attempt to reconcile the poor empirical performance of the Krugman model with the reality of exchange rate target zone regimes, this line of research integrates target zones with alternative underlying economic models, such as imperfect credibility, intra‐marginal interventions and sticky price models. It was thus possible to understand the correlations observed between the exchange rate, its fundamentals determinants and the interest rate differential, and to explain the fact that the statistical distribution of the exchange rate is hump shaped rather than U shaped. This implies that the initial emphasis of target zone models on nonlinearities, ‘honeymoon effect’, ‘smooth pasting’ and marginal interventions has vanished. Exchange rate target zones are better described as similar to managed floating regimes with intra‐marginal interventions, with some marginal interventions when the exchange rate reaches the edges of the floating band.     

ASSESSING THE REGIONAL ECONOMIC IMPACTS OF DEFENSE ACTIVITIES: A SURVEY OF METHODS

Defense activities exercised in a specific region may alter the region's economic performance. An accurate assessment of the potential economic impacts of defense activities is a valuable undertaking to enable regional planners to prepare for changes. The variety in the methods (among others, input–output models, economic base models, Keynesian regional multipliers, fixed‐effects estimators, and case‐study approaches) inspired by geography, sociology, and political science can pose a dilemma. We detail the historical and theoretical background of each method, as well as select exemplary cases where these methods were applied. By examining old and “new” methods, we aim to construct a typology that could be valuable to all stakeholders. In this sense, defense economics can also contribute to the allied social sciences by outlining evaluation methods that may be applicable to other fields.

THE DEMAND FOR BEER,WINE AND SPIRITS: A SURVEY OF THE LITERATURE

Abstract The demand for alcohol literature is vast and much conflicting information about the nature of the demand for alcoholic beverages has been published. This paper presents a survey of the literature, and then uses the technique of meta‐regression analysis to establish insights into the nature of the demand for beer, wine and spirits. Unlike previous meta‐studies of the demand for alcoholic beverages this study adjusts for the precision of each elasticity estimate. The analysis presented suggests reported elasticity estimates will be influenced by such factors as estimation technique, data frequency and time period under consideration. With respect to time, the findings suggest that the demand for alcoholic beverages has become less inelastic since the mid‐1950s and that the income elasticity has been falling since the mid‐1960s. The analysis also found support for the idea that alcohol as a commodity group is a necessity, and that consumers respond to price discounting with inventory behaviour rather than true substitution behaviour. Little support is found for the idea that the demand for alcoholic beverages varies fundamentally across most countries, although wine may be an exception.     

THE EVOLUTION OF STOCK MARKET EFFICIENCY OVER TIME: A SURVEY OF THE EMPIRICAL LITERATURE

Abstract This paper provides a systematic review of the weak‐form market efficiency literature that examines return predictability from past price changes, with an exclusive focus on the stock markets. Our survey shows that the bulk of the empirical studies examine whether the stock market under study is or is not weak‐form efficient in the absolute sense, assuming that the level of market efficiency remains unchanged throughout the estimation period. However, the possibility of time‐varying weak‐form market efficiency has received increasing attention in recent years. We categorize these emerging studies based on the research framework adopted, namely non‐overlapping sub‐period analysis, time‐varying parameter model and rolling estimation window. An encouraging development is that the documented empirical evidence of evolving stock return predictability can be rationalized within the framework of the adaptive markets hypothesis.     

INTERCHANGE FEES IN PAYMENT CARD SYSTEMS: A SURVEY OF THE LITERATURE

Abstract This paper surveys the recent literature about interchange fees in payment card systems. Interchange fees are used by payment platforms to allocate the total cost of a payment card transaction between the cardholder's bank, the issuer, and the merchant's bank, the acquirer. Each time a consumer pays by card, its bank receives an interchange fee from the merchants' bank. Banks argue that interchange fees are needed to encourage the use of electronic payment instruments, whereas merchants claim that they artificially inflate the cost of accepting cards. This paper sheds light on the ongoing debate that opposes banks to the regulatory institutions or the competition authorities in various countries, by reviewing the theoretical results of the literature and highlighting some unanswered issues.     

THE ECONOMIC CAUSES OF OBESITY: A SURVEY

Abstract.  Obesity rates have increased dramatically over the last 30 years. Rising obesity has developed into a considerable worldwide public health problem with significant economic and social consequences. Accordingly, obesity has become a subject of economic research. This paper provides a broad survey of the recent and growing economic literature on the causes of obesity. The literature, both theoretical and empirical, overall aims to explain the rising obesity trend and to identify the factors that contribute to obesity. Also surveyed are non-economic causes and consequences of obesity and the interconnection with economic influences. An understanding of the causes of obesity allows policies to be considered that might stem the global increase in obesity.     

THE CAUSES OF CHILDHOOD OBESITY: A SURVEY

Childhood obesity rates are rapidly rising in many countries. Because it is highly likely that obesity will persist into adulthood, current rates undermine the health and future of people in developed as well as developing countries. This public health epidemic carries significant economic, social as well as individual‐level consequences and has become a research topic of significant interest in various disciplines including economics. We survey the literature in economics and related disciplines associated with the causes of childhood obesity and synthesize the results to provide a better understanding of the explanations for the rising childhood obesity rates. This is an important step in crafting effective policies to combat global childhood obesity trends.     

THE CLIOMETRICS OF INTERNATIONAL MIGRATION: A SURVEY

Abstract This is a survey of some of the key studies in the literature on international migration in history that may be described as cliometric. This literature uses the concepts and approaches of applied economics to investigate a range of historical issues and there are strong parallels with the questions that have been addressed in the literature on contemporary migrations. Here I focus on the period 1850–1940 and chiefly on migration from Europe to the New World. The survey is organized around six themes that include the forces driving migration, over time and across space; the assimilation of migrants and their effects on wages and income distribution in source and destination countries; and the evolution of immigration policy. Although this literature has drawn heavily on the tool kit of applied economists it also provides a wider perspective on many of the issues that concern migration today.     

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.     

THE IMPACT OF THE AFFILIATION OF VENTURE CAPITAL FIRMS: A SURVEY

The aim of this paper is to review the theoretical and empirical literature on the impact of the affiliation of venture capital (VC) firms with a particular focus on the differences between Europe and the US. A main characteristic of VC firms is their high level of involvement in the management of funded firms. However, the VC industry is composed of heterogeneous actors. The literature has studied to a great degree the independent funds that dominate the US market. Yet, there also exist VC funds affiliated with banks or with industrial firm, which can benefit from synergies with their parent corporation. Several studies have highlighted significant differences between these types of VC firms.     

Rationality, Ethnicity And Institutions: A Survey Of Issues And Results

Abstract.  This paper focuses on the relationship between institutions and ethnocentrism as discussed in the rational choice literature. The institutional environment can influence both the formation and the expression of ethnic tastes by rational individuals. Ethnocentrism is likely to be mitigated by, on the one hand, a private sector characterized by a wide and competitive market with effective property right and antitrust law enforcement provided by non-ethnic institutions and, on the other hand, a public sector which is characterized by institutional restrictions on the differential fiscal or regulatory treatment on the basis of ethnicity, a redistributive system based on non-ethnic criteria and finally, the possibility for decentralized collective decision making. These insights may be of particular utility when designing the institutions of potentially divided multi-ethnic states.
