This survey examines the empirical literature on the relationship between public R&D subsidies and private R&D investment over the past five decades. The survey reveals a considerable heterogeneity of empirical results that cannot be explained fully by methodological issues. We aim to provide further explanations of the possible causes of that heterogeneity. In particular, we emphasise a set of issues that, in our view, are critical to understanding the potential effect of public R&D subsidies on private R&D spending. Special attention is paid to the dynamic aspects and composition of firm R&D, the constraints faced by the firm (such as financial constraints), and the amount and source of public subsidies. None of these issues have been investigated in depth. We formulate a set of research assumptions to guide future empirical research in this field.  相似文献

THE ECONOMIC CAUSES OF OBESITY: A SURVEY   总被引:1,自引:0,他引:1  
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.  相似文献

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.  相似文献

Trade liberalization and regional economic integration have recently accelerated in East Asia, where several free trade areas have been established or are under negotiation. Vietnam, after acquiring Association of Southeast Asian Nations (ASEAN) membership in 1995, has signed a bilateral trade package with the United States and participated in the China-ASEAN free trade area. This paper attempts to analyze the impact on Vietnam of ongoing regional economic integration, focusing on growth, poverty reduction and income distribution. For this purpose, we have constructed a globally linked Computable General Equilibrium (CGE) model and made use of Global Trade Analysis Project (GTAP) database version 6.0 and Vietnam's living standards surveys. The simulation analysis shows that the regional economic integration generally has a positive impact. It both enhances welfare and improves income-distribution for Vietnam. Household income and consumption increase, and poor and rural household groups benefit more than urban high income groups.  相似文献

Indonesia continually tries to open its economy through free trade areas (FTAs) on bilateral, regional, and multilateral bases. This paper discusses the impacts of FTAs on the Indonesian economy, particularly for economic growth, poverty, and income distribution. By using a Global Computable General Equilibrium (GCGE) model, we conducted the simulation analysis by setting eighteen scenarios for the ongoing and potential FTAs of different frameworks. Indonesia is found to benefit from joining in FTAs, except for the FTA with India. It is also implied that FTAs increase rural household income at higher rates than they increase urban household income. Moreover, FTAs' impacts are more favorable for unskilled workers than for skilled ones, and also for relatively poor households more than for rich households, both in urban and rural areas. In brief, FTAs provide Indonesia with income redistribution effects.  相似文献

We provide a review of theoretical and empirical contributions on the economic analysis of terrorism and counterterrorism. We argue that simple rational‐choice models of terrorist behavior – in the form of cost‐benefit models – already provide a well‐founded theoretical framework for the study of terrorism and counterterrorism. We also hint at their limitations which relate to the failure of accounting for the dynamics between terrorism and counterterrorism that may produce unintended second‐order effects as well as for the costs associated with counterterrorism and its international dimension. We reevaluate previously proposed counterterrorism strategies accordingly. Finally, in the light of our findings, we discuss interesting areas of future research.  相似文献

Abstract The focus of this survey is to discuss different attempts at incorporating the distributional dimension of human capital into the theoretical and empirical growth framework. We present a series of models which deviate from the direct link between the aggregate or average level of human capital and economic growth in that they introduce the distribution of education as a new element in explaining the relationship under investigation. After surveying the theoretical literature, we present recent empirical work on the relation between economic performance and the average level, as well as the distribution of education, respectively.  相似文献

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.  相似文献

Abstract In this paper, we review economic theories and empirical studies on the socio‐economic aspects of suicide. Through our survey, we would like to emphasize the importance of studying suicide by employing a ‘rational’ approach that complements the medical perspective on suicide. We first introduce major economic theories of suicide and then present a summary of a variety of empirical studies from the socio‐economic perspective. To shed light on the mixed empirical evidence, we employ a meta‐regression method to investigate how the existing empirical results vary. We have identified a publication bias, not highlighted previously, in the existing literature with respect to several commonly employed socio‐economic factors. Several characteristics of existing studies have been identified as influencing the qualitative outcome. We then discuss the recent developments in economic studies on suicide, on the basis of the authors’ ongoing project on suicide. In the concluding section, we point out some issues for further studies.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献
